RESUMO
Objective: To investigate the clinical characteristics and treatment outcomes of glaucoma secondary to congenital ectropion uveae (CEU) using penetrating Schlemm's canaloplasty. Methods: This was a retrospective case series study. Medical records of patients diagnosed with glaucoma secondary to CEU and undergoing penetrating Schlemm's canaloplasty at the Eye Hospital of Wenzhou Medical University between August 2020 and December 2021 were collected. Clinical characteristics including the extent and location of iris ectropion, type of glaucoma, were analyzed. Follow-up visits were conducted at 1, 3, 6 months, and 1 year postoperatively. Visual acuity, intraocular pressure (IOP), anterior segment and fundus condition, filtering bleb morphology, use of IOP-lowering medications, ultrasound biomicroscopy results, and other indicators were analyzed to summarize surgical outcomes. Results: Six cases (6 eyes) of glaucoma secondary to CEU were included, all unilateral, with 3 left eyes and 3 right eyes; median age was 10.0 (5.3, 28.8) years; including 3 males and 3 females. Preoperative IOP was (31.7±10.0) mmHg (1 mmHg=0.133 kPa), and the preoperative number of IOP-lowering medications used was 2.0 (2.0, 3.2). The extent of iris ectropion in the 6 cases ranged from 270 ° to 360 °, with peripheral anterior synechiae corresponding to the location of iris ectropion, and angle closure with the degree of synechiae extending beyond Schwalbe's line. No surgical complications occurred in any of the 6 cases postoperatively. At 1 month postoperatively, the IOP was (16.4±3.2) mmHg, with a median of 0.0 (0.0, 1.5) medications used. At 3 months postoperatively, the IOP was (14.8±6.0) mmHg, with a median of 0.0 (0.0, 2.2) medications used. At 6 months postoperatively, the IOP was (18.1±6.1) mmHg, with a median of 0.0 (0.0, 0.5) medications used. Among them, 5 patients had a follow-up period of 1 year postoperatively, all achieving controlled IOP without the use of IOP-lowering medications, with an average IOP of (15.5±3.1) mmHg. No obvious filtering bleb formation was observed at the surgical site in all patients. Conclusions: Glaucoma secondary to CEU manifests primarily as closed-angle glaucoma, with a correspondence between the closure range of anterior iris adhesions in the angle and the extent of iris ectropion. Penetrating Schlemm's canaloplasty demonstrates favorable and stable efficacy for its treatment.

Objective: To investigate the effect of embryo quality at different developmental stages on the secondary sex ratio (SSR) of single live birth neonates. Methods: Data for patients with singleton live births after embryo transferred between January 2016 and January 2022 were retrospectively analyzed. The effect of embryo quality at different development stages on the SSR of 11 713 singleton live births were investigated. The association of SSR and embryo quality at different development stages was examined in univariate analysis and in a multivariate logistic regression model, after adjustment for confounders, using two models (â and â ¡). Results: The age of both male and female, body mass index of both male and female, basal follicle stimulating hormone and estradiol, smoking of male, methods of insemination, methods of sperm extraction, types of transfer cycle and the number of embryo transferred were not related with SSR (all P>0.05). After adjustment for confounders, the probability of a male live birth was higher after transfer of good-quality blastula than after transfer of poorer-quality blastula (model â : aOR=0.73, 95%CI: 0.65-0.82, P<0.001; model â ¡: aOR=0.73, 95%CI: 0.65-0.82, P<0.001). The quality of cleavage stage embryo was not associated with SSR (model â : aOR=0.99, 95%CI: 0.87-1.13, P=0.937; model â ¡: aOR=0.99, 95%CI: 0.87-1.13, P=0.899). Conclusions: The SSR of singleton live births after embryo transfer is not correlated with the quality of cleavage stage embryo, but is correlated with the quality of blastula. Good-quality blastula transfer is more likely to result in a male live birth.

OBJECTIVE: To investigate the clinicopathological features and prognostic characteristics of papillary renal cell carcinoma (pRCC). METHODS: The clinical data of 114 patients with pRCC, including 91 males and 23 females, admitted to the Department of Urology, Peking University Third Hospital from May 2012 to May 2021 were retrospectively analyzed. All the cases were operated patients with clear pathological diagnosis and complete follow-up data. The log-rank test was used to analyze the relationship between the patients' clinicopathological characteristics and survival time, the Kaplan-Meier method to draw survival curves, and the Cox regression model for univariate and multifactorial analysis. RESULTS: The mean age of the 114 patients was (57.3±12.6) years. The tumors were located in the left kidney in 49 cases and in the right kidney in 65 cases. In the study, 48 radical nephrectomies and 66 partial nephrectomies were performed, 42 cases were type 1 and 72 cases were type 2, and the mean maximum tumor diameter was (5.5±3.6) cm. pT1a stage 52 cases, pT1b stage 22 cases, pT2 stage 4 cases, pT3 stage 33 cases, and pT4 stage 3 cases were staged. According to the World Health Organization / International Society of Urological Pathology (WHO/ISUP), there were 13 cases of gradeâ , 44 cases of grade â ¡, 51 cases of grade â ¢, and 6 cases of grade â £. And 34 of the 114 patients had vascular cancer embolism, 30 cases had lymph node metastasis, and 3 cases had adrenal metastasis. The median follow-up time after surgery was 22 months, and the 3-year progression-free survival rate was 95.6%. The patients with type 1 and type 2 pRCC showed statistically significant differences in age (P=0.046), body mass index (P=0.008), surgical approach (P=0.001), maximum tumor diameter (P < 0.001), vascular cancer embolism (P < 0.001), lymph node metastasis (P < 0.001), pT stage (P < 0.001), and nuclear grade (P < 0.001). The 3-year progression-free survival rates for type 1 and type 2 pRCC were 100% and 69.4%, respectively, with type 1 having a significantly better prognosis than with type 2 (P=0.003). Univariate analysis of the patients with type 2 pRCC showed that pT stage (P < 0.001), vascular cancer embolism (P < 0.001) and lymph node metastasis (P < 0.001) were strongly associated with their prognosis. Multifactorial analysis showed that vascular cancer embolism was an independent prognostic factor for progression-free survival in type 2 pRCC (P=0.001). Univariate analysis of the pRCC patients undergoing radical nephrectomy showed that pT stage (P=0.006), vascular cancer embolism (P=0.001), and lymph node metastasis (P=0.008) were significant factors affecting their prognosis, and further multifactorial analysis showed that only vascular cancer embolism was an indepen-dent prognostic factor for their progression-free survival (P=0.006). CONCLUSION: Type 2 pRCC has more morbidity, more lymph node metastases, more advanced pT stage, and higher pathologic grading than type 1 pRCC. The presence of vascular cancer embolism is an independent prognostic factor in patients with type 2 pRCC and pRCC undergoing radical nephrectomy.

OBJECTIVE: To investigate the treatment and prognosis of multiple primary malignant neoplasms (MPMN) complicated with renal cell carcinoma (RCC), and to make risk stratification. METHODS: A retrospective study of 27 cases of MPMN with RCC in two centers, including the different tumors of MPMN, specific treatment methods, and the interval between primary cancers. At the same time, the survival conditions, including recurrence, metastasis and survival, were followed up for statistical analysis. The interval between the two kinds of primary cancer within 6 months was simultaneous MPMNs, and more than 6 months was metachronous MPMNs. For simple risk stratification of cases, as long as one of the MPMNs had a stage â ¢ or higher malignancy, which was defined as high risk. RESULTS: Among the 27 patients, 20 were male and 7 were female, with age at the time of diagnosis was 42-82 years, with an average age of (61.3±11.7) years. The age at the diagnosis of renal cancer was 43-87 years, with an average age of (66.0±11.3) years. There were 21 cases with duplex primary malignant neoplasms, 4 cases with triple primary malignant neoplasms, and 2 cases with quadruple primary malignant neoplasms. The interval between first cancer and second cancer was 0-360 months, with a median of 18 months. There were 17 cases of metachronous multiple primary malignant neoplasms and 10 cases of simultaneous multiple primary malignant neoplasms. The most common system of MPMN with comorbid RCC involved urologic system, digestive system and respiratory system. The most common locations of MPMN with comorbid RCC were bladder cancer, lung cancer and colon cancer. Follow-up time calcu- lated from the last cancer was 2-156 months, with a median of 32 months. And 14 cases survived and 13 cases died, with 11 cases being tumor related. Tumor stage was the risk factor of prognosis. Any kind of tumor stage in stage â ¢ or above had a relatively poor prognosis. CONCLUSION: MPMN complicated with RCC is relatively rare. Standard treatment should be used for each cancer type during the treatment process. The prognosis mainly depends on the highest stage of each tumor. Simple risk stratification shows that the prognosis of the high-risk group is worse. This simple stratification method may be helpful to predict the prognosis.

Objective: To explore the related factors of poor ovarian response (POR) in patients receiving controlled ovarian stimulation (COS) and to establish the nomogram for predicting POR in patients who received in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI). Methods: In this retrospective research, clinical data of 17 164 cycles of patients who received IVF/ICSI treatment at Henan Provincial People's Hospital from September 1st, 2016 to September 1st, 2020 were analyzed. Independent correlative factors affecting the occurrence of POR were screened by logistic regression, which were the model enrollment variables in the prediction model. Totally 13 266 cycles with well-record of enrollment variables were screened, and these data were randomly divided into model group (9 896 patients) and validation group (3 370 patients) according to 3â¶1. The nomogram was established according to the regression coefficient of the relevant variables. The prediction accuracy of the nomogram was evaluated by calculating area under the receiver operating characteristic curve (AUC). Results: Multivariate logistic regression analysis showed age, infertility type, body mass index, anti-Müllerian hormone, basal follicle stimulating hormone, basal estrogen, antral follicle number, previous times of POR, history of ovarian surgery, ovulation stimulation protocol and average amount of gonadotropin were independent correlative factors affecting the occurrence of POR (all P<0.05). In the model group, according to the above factors, the prediction model and nomogram of POR risk were constructed and the validation group verified the model. The AUC of the model group was 0.893 (95%CI: 0.885-0.900), and the AUC of the validation group was 0.890 (95%CI: 0.878-0.903). Conclusion: The influencing factors of POR after COS in patients treated by IVF/ICSI are screened, and the nomogram for predicting POR established in this study is proved to be effective, simple, intuitive and clear in predicting the occurrence of POR.

Objective: To investigate the clinical features in patients with iridocorneal endothelial (ICE) syndrome. Methods: A retrospective case series study. Data of clinical manifestations of patients with ICE syndrome including clinical subtypes, presenting visual acuity, clinical features and secondary glaucoma were collected from January 2014 to May 2020 in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University. The Wald's Chi-square test of generalized estimating equations was performed to analyze the differences in three clinical subtypes. Results: A total of 127 eyes of 114 subjects (64 females and 50 males) were included. Mean±SD age at presentation was (49±13) years. There were 53 patients (46.5%) with Chandler's syndrome (CS), 36 patients (31.6%) with progressive iris atrophy (PIA), 24 patients (21.0%) with Cogan-Reese syndrome (CRS) and one patient (0.9%) with an undetermined subtype. And 101 patients (88.6%) had uniocular ICE syndrome. Approximately 81.7% (49/60), 56.1% (23/41) and 41.7% (10/24) of eyes presented visual acuity <0.3 in patients with CS, PIA and CRS, respectively. Corneal edema was most common in CS (52.5%, 32/61), followed by PIA (29.3%, 12/41) and CRS (20.8%, 5/24). Corectopia was found in 95.8% (23/24) of eyes with CRS, 95.1% (39/41) of eyes with PIA and 78.7% (48/61) of eyes with CS. Polycoria was observed in 29.3% (12/41) of eyes with PIA, 3.3% (2/61) of eyes with CS and 8.3% (2/24) of eyes with CRS. Ectropion uvea was most common in CRS (54.2%, 13/24), followed by 16.4% (10/61) in CS and 12.2% (5/41) in PIA. Glaucoma was found in 94 eyes (74.0%, 94/127). Among them, 60.7% (37/61) of CS, 80.5% (33/41) of PIA and 95.8% (23/24) of CRS had secondary glaucoma. The difference of presenting visual acuity, corneal edema, corectopia, polycoria, ectropion uveae and secondary glaucoma in three clinical subtypes all had statistical significance (Wald χ2=13.87, 10.77, 965.78, 11.45, 15.00, 222.04; all P<0.05). And 86.2% of eyes (81/94) had glaucoma surgeries and 41 eyes (43.6%, 41/94) had the intraocular pressure well controlled with various interventions. Conclusions: ICE syndrome is mostly uniocular and more common in middle-aged patients. CS is the most common clinical subtype with poor presenting visual acuity. About 3/4 of eyes have secondary glaucoma, and the majority of them require surgical interventions, but prognoses are discouraging.

A total of 170 consecutive patients (181 eyes) who were diagnosed with primary angle-closure glaucoma (PACG) and underwent phacoemulsification and intraocular lens implantation (PEI) combined with goniosynechialysis (GSL) with an instrument under a gonioscope in the Eye Hospital, Wenzhou Medical University from January 1, 2017 to December 31, 2019 were observed. Anterior chamber angle synechiae of 0 (0, 2) clock hour were released after PEI, while after combined goniosynechialysis, synechiae of 6 (3, 8) clock hours were further released. No matter in chronic PACG and acute PACG with cornea edema, the extent of anterior chamber angle synechiae was different before surgery and after PEI, and so was it in post-PEI and PEI-GSL prospectively (all P<0.01). Phacoemulsification alone can reopen the synechial anterior chamber angle in both chronic PACG and acute PACG in part, but not sufficiently. Combined goniosynechialysis under a gonioscope with an instrument is essential and effective.

Objective: To report the incidence and time distribution of early transient intraocular pressure (IOP) elevation after penetrating canaloplasty. Methods: Retrospective case series study. Data of patients treated by penetrating canaloplasty for glaucoma in the Eye Hospital of Wenzhou Medical University from June 2015 to March 2020 were collected. Early transient IOP elevation was defined as an increase of IOP to over 21 mmHg on the first week to the third month after surgery followed by a decrease to 21 mmHg or less within 3 months. Main outcome measures included IOP, quantity of medication use, the occurrence time and duration of IOP elevation. Generalized estimating equations were used for statistical analysis, and measurement data with non-normal distribution was represented as M (Q1, Q3). Results: A total of 277 patients (315 eyes) achieved 360-degree catheterization of the canal successfully, and 299 eyes (94.9%) completed the postoperative 6-month follow-up. Thirty-four eyes (10.8%) had persistently high IOP, so the surgical treatment failed in them. Consequently, 234 patients (265 eyes) were enrolled in the analyses, including 161 males (184 eyes) and 73 females (81 eyes). The median age was 42 (26, 54) years, the mean preoperative IOP was (37.7±11.1) mmHg, and the mean number of drugs used was 3 (2, 4). The incidence of early transient IOP elevation was 43.0% (114/265) in all enrolled eyes, 42.7% (35/82) in eyes with primary open angle glaucoma, 37.8% (17/45) in eyes with primary angle closure glaucoma, 27.7% (13/47) in eyes with congenital glaucoma and 53.8% (49/91) in eyes with secondary glaucoma. The IOP began to increase on the first to fourth week in 91.2% (104/114) of eyes with early transient IOP elevation and reached the peak [21.3 mmHg to 54.8 mmHg; mean, (32.4±8.2) mmHg] in 88.6% (101/114) on the first to fifth week after surgery. The IOP elevation lasted for no more than 4 weeks in 69.3% (79/114) of eyes. Conclusions: Over 40.0% of patients with penetrating canaloplasty may experience postoperative transient IOP elevation. The incidence is relatively high in secondary glaucoma but low in congenital glaucoma. Most of the elevations and peak IOP occur within 1-4 weeks after surgery.

Objective: To evaluate the expression and clinical significance of γ-glutamylcyclotransferase (GGCT) in patients with bladder urothelial cell carcinoma. Methods: Immunohistochemical staining for GGCT were performed on tissue sections of 86 patients with bladder urothelial cell carcinoma and 10 normal controls, and the correlations between GGCT and clinicopathological characteristics and the prognosis were analyzed. Results: The positive rate of the expression of GGCT in 86 cases of bladder urothelial cell carcinoma was 61.6% (53/86). GGCT protein was located mainly in cancer cell cytoplasm, and it can be seen in the nucleus of the tumor cells in some cases. The level of GGCT expression was positively related to pathological classification (P<0.001), stage (P=0.020), and tumor size (P=0.025). Immunohistochemical semiquantitative analysis showed that the expression of GGCT in patients with T1 stage of non-muscle invasion bladder urothelial cell carcinoma was significantly higher than that with Ta stage (P=0.034). Kaplan-Meier analysis showed that the expression of GGCT was correlated with the recurrence-free survival in patients with non-muscle invasive bladder cancer, the recurrence-free survival rate was lower in the GGCT positive group (P=0.029). Multivariate COX regression analysis showed that the pathological stage (OR=5.029, P=0.009) and the number of tumors (OR=3.320, P=0.024)were the independent risk factors for recurrence-free survival in patients with early urothelial cell carcinoma of the bladder. Conclusions: The expression of GGCT is significantly increased in bladder urothelial cell carcinoma and is related to the malignant biological behavior and progression of tumor. Patients with GGCT positive early bladder tumor are inclined to recur.

OBJECTIVE: To evaluate the relationship between recovery of urinary continence after laparoscopic radical prostatectomy (LRP) and preoperative prostate apex depth (PAD) on magnetic resonance imaging (MRI). METHODS: We retrospectively analyzed 184 patients with pathologic confirmed prostate carcinoma who underwent LRP in Department of Urology, Peking University Third Hospital. All the patients received MRI examination before surgery. Membranous urethral length (MUL) was defined as the distance from the apex of prostate to the level of the urethra at penile bulb on the coronal image. PAD was defined as the distance from the apex of prostate to the suprapubic ridge line on sagittal MRI. PAD ratio (PADR) was defined as PAD/pubic height. All the patients received extraperitoneal LRP. The patients' reporting freedom from using safety pad (0 pad/d) were defined as urinary continence. Univariate and multivariate regression analyses were used to identify independent predictors of early continence recovery after LRP. Kaplan-Meier analyses and log-rank test were used to compare time to continence recovery between the groups. RESULTS: For all the 184 patients, the average age was (69.0±7.7) years, the ave-rage mass index(BMI) was (25.07±3.29) kg/m2, and the pre-biopsy PSA was (16.80±21.99) g/L. For all the patients who underwent MRI preoperatively, the mean PV was (39.35±25.25) mL and the mean MUL was (14.0±3.7) mm. The mean PAD was (24.52±4.97) mm and the mean PADR was 0.70±0.14. The continence rate for all the patients after LRP was 62.0% and 96.2% in three months and one year. The patients achieving early continence recovery had significant smaller PV (P=0.049), longer MUL (P < 0.001) and higher PADR (P=0.005). Multivariate analysis revealed MUL (P < 0.001) and PADR (P=0.032) were predictors of continence recovery after LRP. Kaplan-Meier analyses and Log-rank test revealed that MUL (≥14 mm vs. < 14 mm, P < 0.001) and PADR (≥0.70 vs. < 0.70, P < 0.001), PV(< 50 mL vs. ≥50 mL, P=0.001) were all significantly associated with continence recovery. CONCLUSION: MUL and PADR are independent predictors of early continence recovery after LRP. MUL, PADR and PV are significantly associated with recovery of urinary continence.

OBJECTIVE: To explore the surgical strategy and experience of reoperation for pheochromocytoma and paraganglioma which is very challenging. METHODS: The clinical data of 7 patients with pheochromocytoma and paraganglioma who underwent reoperation in Department of Urology, Peking University Third Hospital from August 2016 to February 2021 were analyzed retrospectively. There were 4 males and 3 females, with an average age of (44.1±11.5) years (28-60 years), 6 cases on the right side and 1 case on the left side. The causes of the operations included: (1) 2 cases of tumor recurrence after resection; (2) The primary operations failed to completely remove the tumors in 3 cases, because the tumors were large and closely related to blood vessels. (3) Pheochromocytoma and paraganglioma wasn't diagnosed before primary operation, therefore, drug preparation wasn't prepared. Two cases were interrupted by severe blood pressure fluctuations during the primary operations. Imaging evaluation, catecholamine biochemical examination and adequate adrenergic α receptor blockers were administrated in all the cases. The surgical approaches included open transperitoneal surgery in 4 cases, robot-assisted laparoscopy in 1 case and retroperitoneal laparoscopy in 2 cases. The innovative techniques included mobilization of the liver, inferior vena cava transection and anastomosis, and transection of left renal vein. RESULTS: The average tumor size was (8.0±3.2) cm (3.6-13.9 cm). The median interval between the reoperation and the primary operation was 9 months (IQR: 6, 19 months). The median operation time was 407 min (IQR: 114, 430 min) and the median blood loss was 1 500 mL (IQR: 20, 3 800 mL). Operations of 5 cases were performed successfully, and 1 case failed only by exploration during the operation. One case died perioperatively. There were 5 cases of intraoperative blood transfusion, the median transfusion volume of red blood cells was 800 mL (IQR: 0, 2 000 mL). One case experienced postoperative lymphorrhagia, and recovered after conservative treatment. The renal function was normal in 2 cases after resection and anastomosis of inferior vena cava or transection of left renal vein. The average postoperative hospital stay was (7.2±3.3) d (4-13 d). The median follow-up time of 6 patients was 33.5 months (IQR: 4.8, 48.0 months). The case who failed in the reoperation still survived with tumor and there was no recurrence in the rest of the patients. CONCLUSION: The reoperation of pheochromocytoma and paraganglioma, which can not be resected in the primary operation or recurred postoperatively, is difficult with high risk of hemorrhage, and there is a risk of failure and perioperative death. Different surgical approaches and strategies need to be adopted based on the different situation.

Objective: To evaluate the quality of life of patients with primary open-angle glaucoma (POAG) and its related factors in Wenzhou. Methods: Cross-sectional analysis. A total of 339 POAG patients diagnosed in the Wenzhou glaucoma progression study conducted in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University from March 2014 to October 2019 were included. Quality of life of POAG patients was assessed by EQ-5D including the visual analogue scale (VAS). The effects of gender, age, visual field loss (VFL), family history of glaucoma, hypertension, diabetes, migraine, sleep quality, and amateur exercise on the quality of life were analyzed. The utility value (UV) and VAS score were expressed as the median (P25, P75), and Mann-Whitney U was used for the comparison between two groups. Kruskal-Wallis H was performed to compare the differences among multiple groups. Results: A total of 339 POAG patients were included in the study; 164 were males (48.4%), and 175 were females (51.6%). The mean age was (63±10) years. Thirty-four patients (10.0%) had received medication (including one with combined surgical treatment), while the remaining 305 patients (90.0%) had received no anti-glaucoma treatment. Among the patients, 10.5% (32/305) had no VFL, 68.9% (210/305) had mild VFL, 17.0% (52/305) had moderate VFL, and 3.6% (11/305) had severe VFL. In all patients, the median of UV was 1.000 (1.000, 1.000), the mean of UV was 0.964, and the median of VAS score was 80 (75, 90), the mean of VAS score was 81.58. Anxiety or depression and pain or discomfort occurred in 45.7% (43/94) and 34.1% (32/94), respectively, of POAG patients with decreased UVs, as well as mobility constraints in 13.8 % (13/94) and usual activity constraints in 6.4% (6/94). The median of UV of the eye with a better visual field in the group without VFL or with mild or moderate VFL was 1.000 (1.000, 1.000), and in the group with severe VFL was 1.000 (0.862, 1.000), but there was no significant difference in the UV and the VAS score of the eye with a better visual field among groups with different degrees of VFL (both P>0.05). There was statistically significant difference in the UV among groups with different sleep qualities (H=17.465; P<0.01). Using pairwise comparison, the median of UV of the very good sleep group was 1.000 (1.000, 1.000), significantly different to the slightly poor sleep group 1.000 (0.866, 1.000) (z=3.613; P<0.05). The median of UV in patients with migraine was 1.000 (0.875, 1.000), without migraine 1.000 (1.000, 1.000), and in patients with hypertension was 1.000 (0.875, 1.000), without hypertension 1.000 (1.000, 1.000), and in patients with diabetes was 1.000 (0.875, 1.000), without diabetes was 1.000 (1.000, 1.000), the difference was statistically significant (Z=-2.189, -3.864, -2.417; all P<0.05). The UV was not related to age, gender, family history of glaucoma, amateur exercise, alcohol and tobacco, and history of anti-glaucoma medication (all P>0.05). Conclusions: VFL is related to the UV of POAG patients in Wenzhou. Quality of life in mild POAG patients is good but decrease in advanced POAG patients. Sleep quality, systemic complications and physical or psychological discomfort impact on quality of life in POAG patients. (Chin J Ophthalmol, 2021, 57: 207-214).

Objective: To describe the distribution and characteristics of peripheral anterior synechiae (PAS) in patients with primary angle-closure glaucoma (PACG). Methods: Retrospective case study. A total of 285 PACG patients (406 eyes) diagnosed in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University from January 2017 to August 2019 were included. They were 102 males and 183 females, with a median age of 67 years old (range, 21 to 95 years old). The PAS range was detected by gonioscopy examination, and the frequency distribution of PAS at 12 clock points was counted by clockwise. The PAS distribution at the middle point of PAS with continuous distribution and ≤6 clock points was assessed. Results: In all cases, PAS of the right eye was concentrated at 11:00 to 4:00 regions [range, 62.0% (129/208) to 78.8% (164/208)]. PAS of the left eye was concentrated at 7:00 to 1:00 regions [range, 50.0% (99/198) to 75.8% (150/198)]. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 3:00 [range, 58.3% (74/127) to 67.7% (86/127)] in the right eye and at 10:00 to 12:00 [range, 54.8% (68/124) to 66.1% (82/124)] in the left eye. Among 121 cases (242 eyes) with both eyes involved, the PAS region was at 11:00 to 5:00 [range, 52.1% (63/121) to 79.3% (96/121)] in the right eye and at 8:00 to 1:00 [range, 50.4% (61/121) to 76.9% (93/121)] in the left eye. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 4:00 [range, 53.2% (41/77) to 71.4% (55/77)] in the right eye and at 10:00 to 12:00 [range, 50.6% (39/77) to 64.9% (50/77)] in the left eye. In all cases, there were 171 cases of right eyes and 175 cases of left eyes with continuous angle PAS. The central PAS clock position of the right eye was mainly at 11:00 to 3:00 [range, 15.2% (26/171) to 24.0% (41/171)], and that of the left eye was mainly at 8:00 to 12:00 [range, 15.4% (27/175) to 20.6% (36/175)]. Among cases with both eyes involved, there were 98 cases of right eyes and 104 cases of left eyes with continuous angle PAS. The clock distribution of the middle position of the right eye angle PAS was concentrated at 11:00 to 3:00 [range, 17.3% (17/98) to 26.5% (26/98)], and that of the left eye was concentrated at 8:00 to 12:00 [range, 13.5% (14/104) to 20.2% (21/104)]. Conclusions: The PAS of PACG patients is mainly located in the upper and nasal sides, and the closer to the temporal side, the smaller the PAS frequency, showing a gradual downward trend. The PAS distribution of binocular angles is of obvious mirror symmetry. (Chin J Ophthalmol, 2021, 57: 666-671).

AIM: To use connectivity mapping, a bioinformatics approach, to identify compounds that could induce odontogenic differentiation of dental pulp cells (DPCs) and to experimentally validate this effect. A subsidiary aim was to investigate the anti-inflammatory effect of any identified compound. METHODOLOGY: The Gene Expression Omnibus (GEO) database was searched for microarray data sets assessing odontogenic differentiation of human DPCs. An odontogenic gene expression signature was generated by differential expression analysis. The statistical significant connectivity map (ssCMap) method was used to identify compounds with a highly correlating gene expression pattern. DPCs were treated with the compound identified, and osteo/odontogenic differentiation was assessed by Alizarin red staining, alkaline phosphatase activity and expression of osteo/odontogenic genes ALPL, RUNX2, COL1A1, DSPP, DMP1 and SPP1 by RT-PCR. The anti-inflammatory effect of the compound was assessed using an ex vivo pulpitis model, and cytokine levels were measured with multiplex assay. Means were compared using the t-test or ANOVA followed by a Bonferroni post hoc test with the level of significance set at P ≤ 0.05. RESULTS: The GEO database search identified a specific gene expression signature for osteo/odontogenic differentiation. Analysis using ssCMap found that acetylsalicylic acid [(ASA)/aspirin] was the drug with the strongest correlation with that gene signature. The treatment of DPCs with 0.05 mmol L-1 ASA showed increased alkaline phosphatase activity (P < 0.001), mineralization (P < 0.05), and increased the expression of the osteo/odontogenic genes, DMP1 and DSPP (P < 0.05). Low concentration (0.05 mmol L-1 ) ASA reduced inflammatory cytokines IL-6 (P < 0.001), CCL21 (P < 0.05) and MMP-9 (P < 0.05) in an ex vivo pulpitis model. CONCLUSIONS: Connectivity mapping, a web-based informatics method, was successfully used to identify aspirin as a candidate drug that could modulate the differentiation of DPCs. Aspirin was shown to induce odontogenic differentiation in DPCs in vitro and this, together with its anti-inflammatory effects, makes it a potential candidate for vital pulp therapies.

OBJECTIVE: To detail a novel technique for marking renal tumors with intravenous indocyanine green (ICG) during laparoscopic partial nephrectomy, and to investigate the feasibility and safety of this technique with the use of near-infrared fluorescence imaging. METHODS: Between July 2019 and January 2020, 25 consecutive cases with renal masses underwent intraoperative ICG tumor marking laparoscopic partial nephrectomy, at the department of urology in Peking University Third Hospital by the same surgeon. The key benefits included quick intraoperative identification of the mass with improved visualization and real-time control of resection margins by the ICG Immunofluorescence imaging technique. Clinical data were prospectively collected in our institutional database. Perioperative, pathological, and clinical outcomes of the partial nephrectomy were assessed. Measurement data with normal distribution and count data were respectively described as M(range) and percentage. Among these cases, 16 cases were male and 9 cases female, The median body mass index was 25.4 (20.0-35.4) kg/m2. The average age was 54 (29-77) years. The maximum tumor diameter was 2.75(1.30-5.20) cm. The R.E.N.A.L score was 7.5 (5.0-10.0).The tumor locations were distributed with upper pole (11, 42%), middle (6, 23%), and lower pole (9, 35%).The clinical stages of the tumor were described as follows: T1aN0M0 (23, 88.5%), T1bN0M0(2, 7.7%), T2aN0M0 (1, 3.8%). RESULTS: All the 25 cases were performed 26 times with intraoperative ICG tumor marking laparoscopic partial nephrectomy. There were no allergy, infection and other complications with intravenous indocyanine green. The surgical procedure was successful in all the patients. No conversion and blood transfusion were needed. All the cases of the surgical margin were negative. Overall the operative time was 136 (50-247) min and warm ischemia time was 14 (7-30) min.The estimated blood loss was 50 (10-400) mL and the hospital stay was 5.5 (3.0-31.0) days. One case with perirenal hematoma, one case with urine leak, one with respiratory failure and deep venous thrombosis. All of these cases were cured by the corresponding treatment. The others had no severe complications. There was no tumor recurrence and metastasis during the follow up with 4 to 10 months. CONCLUSION: ICG marking and near-infrared fluorescence imaging technology has now emerged as a safe, feasible and useful tool that may facilitate laparoscopic partial nephrectomy.

Objective: To evaluate the precision of the robot-assisted sacroiliac screw placement for posterior pelvis injury and the impacting factors. Methods: The clinical data of twenty-four cases of posterior pelvic fractures treated by percutaneous sacroiliac screw placement in Yantai shan Hospital from August 2016 to May 2018 were studied retrospectively. There were 17 males and 7 females with a mean age of 44.1 years (ranged from 17 to 71 years). According to AO classification, 17 cases were type B fractures (9 cases of type B1 and 8 type B2), and 7 cases were type C factures (3 cases of type C1, 2 type C2 and 2 type C3). All cases were treated by robot-assisted percutaneous sacroiliac screw placement (AO cannulated screws with a diameter of 7.3 mm). In the posterior pelvic surgeries for the 24 cases, 26 S(1) sacroiliac screws fixations and 18 S(2) sacroiliac screw fixations were placed in total, with single S(1) segmental fixation in 8 cases, single S(2) segmental fixation in 3 cases, S(1) and S(2) combined fixation in 13 cases, S(1) unidirectional one-sided fixation in 18 cases, S(1) bidirectional two-sided fixation in 3 cases, S(2) unidirectional one-sided fixation in 14 cases, S(2) bidirectional two-sided fixation in 2 cases and S(1) unidirectional double screws fixation in 2 cases. X-ray and CT examinations were taken for all 24 cases after operation. The visual analogue scale (VAS) of pain were performed before and after the operation. Results: All the sacroiliac screws were successfully implanted at once as planned with the assistance of the robot. The postoperative X-ray films and CT showed that none of the sacroiliac screws broke through the sacral body and the contralateral sacral wing's frontal cortex nor did they stray into the sacral canal and the intervertebral space. In 3 cases, the sacroiliac screws went closely against and wore out the front edge of iliac cortical density line and sacral alar slope and finally re-entered the sacral body. In 3 cases, sacroiliac screws touched upon the sacral nerve canals but did not break through the nerve canals. The mean VAS of pain was improved from 7.1 points (4-10 points) before the operation to 1.9 points (0-3 points) after. Conclusions: The robot-assisted sacroiliac screw placement shows high precision, and hence is worthy of clinical promotion; however the primary role of the surgeon could not be replaced.

Objective: To explore the value of anti-Müllerian hormone (AMH) and age in predicting outcomes of patients undergoing in vitro fertilization and embryo transfer treatment. Methods: In this retrospective study, 6 328 Chinese patients who underwent the first in vitro fertilization or intracytoplasmic sperm injection and embryo transfer treatment in Henan Provincial People's Hospital between July 2016 and July 2018 were analyzed. All the patients were categorized into two groups according to pregnancy or not. Baseline data and outcomes of two groups were compared. The regression analysis was conducted to identify the independent factors of clinical pregnancy rates. Furthermore, correlation analysis was performed between AMH and other factors. Results: (1) The total clinical pregnancy rate was 56.86% (3 547/6 238). Age, AMH, basal FSH, antral follicle number (AFC), starting dose of gonadotropin (Gn), total doses of Gn, duration of Gn, number of oocytes, transferable cleavage embryos and transferred embryos were significantly different (all P<0.01). (2) Correlation analysis showed that AMH had significant passive correlation with age, basal FSH, starting dose of Gn and total doses of Gn (all P<0.01), while showed significant positive correlation with AFC, body mass index, duration of Gn, number of oocytes and transferable cleavage embryos (all P<0.01). Of all the factors, AMH had the strongest correlation with AFC (P<0.01). (3) Multivariate logistic regression analysis suggested that age was the independent influencing factor of clinical pregnancy rate (OR=0.938, 95%CI: 0.824-0.952, P<0.01), while AMH not (OR=1.004, 95%CI: 0.984-1.024, P=0.687). In the subgroups according to age, the advanced group (age>35 years old) had lower clinical pregnancy rate and higher cancellation rate for no available embryos. Conclusions: AMH has no predictive value of clinical pregnancy outcomes for patients with in vitro fertilization and embryo transfer treatment, while age has certain predictive value of pregnancy outcomes. AMH level may have indictive value for the evaluation of ovarian reserve.

Objective: To evaluate the preliminary efficacy and safety of penetrating canaloplasty for treating primary angle-closure glaucoma (PACG). Methods: It is a prospective interventional case series study. Twenty-two patients (24 eyes) with PACG were treated with penetrating canaloplasty (video attached) at the Eye Hospital of Wenzhou Medical University from June 2015 to August 2018. This modified canaloplasty was performed by making a window at the corneal-scleral bed. Aqueous was redirected to the opening of Schlemm's canal after the canaloplasty with intension sutures. Postoperative follow-up was made at 1 day, 7 days, 1 month, 3 months, and 6 months. Surgical success was defined as intraocular pressure (IOP) ≤ 21 mmHg (1 mmHg=0.133 kPa) with glaucoma medication (quantified success) and without any glaucoma medication (complete success). Main outcome measures included IOP, number of medication, surgical success rate, complications, and filtering bleb status. One-way repeated measure ANOVA and rank sum test were used in statistical analysis. Results: Due to the failure of circumferential catheterization of the canal, 4 eyes converted to trabeculectomy. A total of 19 PACG patients (20 eyes) achieved the successful 360-degree catheterization of the canal, including 11 males and 8 females. The mean age was (54±7) years old (range: 41-65 years old), and the mean angle-closure range was (326.3±46.6) degrees. The mean preoperative IOP was (38.0±11.9) mmHg with the median medication number of 3 (range: 2-5). The mean postoperative IOP was (14.5±11.1), (16.1±6.0), (17.7±5.5), (15.7±5.0), and (15.4±3.7) mmHg at 1 day, 7 days, 1 month, 3 months, and 6 months, respectively. There was significant difference in IOP between postoperative and preoperative (all P<0.01). The median medication number (range) was 0 (0-3), 0 (0-2), 0(0-3), 0(0-2), and 0 (0-2) at the 5 time points, respectively. There was significant difference in medication number between postoperative and preoperative (all P<0.01). The quantified success rate was 95%(19/20), and the complete success rate was 90%(18/20) at 6 months. Postoperative complications were observed in 7 eyes (35%) of 20 PACG eyes, including 3 eyes (15%) with hyphema, 2 eyes (10%) with shallow anterior chamber, 1 eye (5%) with Descemet membrane detachment, and 1 eye (5%) with filtration obstruction at the trabeculum ostium. According to the results of slit lamp and ultrasound biomicroscopy examinations, 70% of the eyes (14/20) had no filtering bleb. Eight eyes (40%) with IOP spike were observed. Conclusion: Preliminary study shows penetrating canaloplasty is safe and effective in the treatment of PACG, but needs a longer follow-up. (Chin J Ophthalmol, 2019, 55: 448-453).

OBJECTIVE: To assess the perioperative outcome, continence recovery and oncologic outcome of Chinese patients aged 80 years or older treated with radical prostatectomy for prostate cancer. METHODS: We retrospectively evaluated the octogenarian patients who recieved biopsy for prostatic carcinoma and underwent laparoscopic radical prostatectomy from 2007 to 2016. We collected the data of clinical variables, perioperative parameters and postoperative pathological results for the octogenarian patients. We recorded and analyzed the recovery of urinary continence of the patients 3 months, 6 months and 1 year after surgery. Biochemical progression was defined as postoperative prostate specific antigen (PSA) greater than 2 µg/L for 2 times. We evaluated the non-biochemical recurrence survival rate and overall survival rate by Kaplan-Meier survival curve analysis for the patients aged 80 years or older. Multivariable COX regression analyses were used for evaluating the influence factors of biochemical recurrence after laparoscopic radical prostatectomy. RESULTS: For all the 51 patients, the average age was (81.6±1.6) years,and prebiopsy PSA was (15.19±13.68) µg/L. There were 14 cases (27.5%), 19 cases (37.3%) and 18 cases (35.3%) for biopsy Gleason score 6, 7 and ≥8. There were 6 patients (11.8%) with clinical stage T1, 31 patients (60.8%) with clinical stage T2 and 14 patients (27.5%) with clinical stage T3. According to American Society of Anesthesiologists (ASA) classification, grade I was in 6 patients and grade II in 45 patients. All the octogenarian patients received extra-peritoneal laparoscopic radical prostatectomy. The average operation time was (189.6±69.1) min, the estimated blood volume was (169.9±163.5) mL, and 11 patients (21.6%) had perioperative complications. There were 29 cases (56.9%) and 22 cases (43.1%) staged for pT2 and pT3 based on postoperative pathological test. Of the pT3 patients, 18 (35.3%) and 4 (7.8%) were pT3a and pT3b. Eight cases (15.7%) presented Gleason score 6,21 cases (41.1%) 7 and 22 cases(43.1%) ≥8. Fourteen cases were positive surgical margin patients after surgery. Overall, the median follow up was 42 months. The continence rate of the octogenarian patients was 64.7%, 82.4% and 92.2% for 3 months, 6 months and 12 months after the surgery. Twelve cases (23.5%) had biochemical recurrence and 4 cases (7.8%) died in the follow up. There was 1 patient who died of prostate cancer progression and 3 died for other reasons. PSA (P=0.019), pT≥T3 (P=0.017) and positive surgical margin (P=0.020) were independent risk factors for biochemical recurrence of the octogenarian prostate cancer patients according to multivariable COX regression analysis. CONCLUSION: For well selected octogenarian prostate cancer patients, laparoscopic radical prostatectomy was a feasible treatment option. Octogenarian patients who received laparoscopic radical prostatectomy showed good oncologic outcome. PSA, pT≥T3 and positive surgical margin were independent risk factors for biochemical recurrence of octogenarian prostate cancer patients.
