RESUMO
Objective: To investigate the variation of reference ranges of hemodynamic parameters in normal pregnancy and their relation to maternal basic characteristics. Methods: A total of 598 healthy pregnant women who underwent regular prenatal examination at the Third Affiliated Hospital of Guangzhou Medical University from January to December 2023 were prospectively enrolled, and noninvasive hemodynamic monitors were used to detect changes in hemodynamic parameters of the pregnant women with the week of gestation, including cardiac output (CO), stroke volume (SV), thoracic fluid content (TFC), systemic vascular resistance (SVR), mean arterial pressure (MAP), and heart rate (HR). Relationships between hemodynamic parameters and maternal basic characteristics, including age, height, and weight, were analyzed using restricted cubic spline. Results: (1) CO (r=0.155, P<0.001), TFC (r=0.338, P<0.001), MAP (r=0.204, P<0.001), and HR (r=0.352, P<0.001) were positively correlated with the week of gestation, and SV was negatively correlated with the week of gestation (r=-0.158, P<0.001). There was no significant correlation between SVR and gestational age (r=-0.051, P=0.258). (2) CO exhibited a positive correlation with maternal height and weight (all P<0.001). The taller and heavier of pregnant women, the higher their CO. A linear relationship was observed between maternal weight and SV, MAP and HR (all P<0.01). As maternal weight increased, SV, MAP and HR showed an upward trend. Furthermore, there was an inverse association between maternal age and SVR (P<0.001). (3) There was a significant nonlinear association observed between TFC and body mass index during pregnancy (P<0.05). Additionally, a nonlinear relationship was found between SVR and MAP in relation to maternal age (all P<0.05). Notably, when the age exceeded 31 years old, there was an evident upward trend observed in both SVR and MAP. Conclusions: The hemodynamic parameters of normal pregnant women are influenced by their height, body weight, and age. It is advisable to maintain a reasonable weight during pregnancy and give birth at an appropriate age.

Objective: To investigate the efficacy and safety of endoscopic resection of infratemporal fossa mass and to determine the indications for surgery. Methods: A retrospective case series study was conducted, including a total of 29 patients who underwent endoscopic surgery to treat infratemporal fossa mass in the Department of Rhinology of Beijing Tongren Hospital, Capital Medical University, from April 2008 to December 2021. Ten males and 19 females were included in the study, with age of (46.5±13.7) years. Pre-and post-operative sinus CT, sinus or nasopharyngeal enhanced MRI were evaluated, respectively. The main outcome measurements were the total resection of mass and the incidence of surgery-related complications. Results: Among the 29 cases of infratemporal fossa mass, 22 were schwannomas, 3 were cysts, 2 were neurofibromas, 1 was pleomorphic adenoma and 1 was basal cell adenoma. Preoperative imaging showed well-defined lesion boundaries, and postoperative pathology confirmed the benign nature of all cases. The endoscopic transnasal approach was used in 28 patients, while the combination of the transnasal approach and the transoral approach was used in 1 patient. Complete tumor removal was achieved in all cases with a 100% resection rate. The average follow-up time was 38 months (7-168 months), and no tumor recurrence was observed. Conclusions: The Endoscopic transnasal approach is a safe and effective surgical approach for the treatment of benign tumors or masses in the infratemporal fossa.

Objective: To investigate the prognoses of advanced (T3-T4) sinonasal malignancies (SNM). Methods: The clinical data of 229 patients with advanced (T3-4) SNM who underwent surgical treatments in the First Affiliated Hospital of Sun Yat-sen University from 2000 to 2018 were retrospectively analyzed, including 162 males and 67 females, aged (46.8±18.5) years old. Among them, 167 cases received endoscopic surgery alone, 30 cases received assisted incision endoscopic surgery, and 32 cases received open surgery. The Kaplan-Meier method was used to estimate the 3-year and 5-year overall survival (OS) and event-free survival (EFS). Univariate and multivariate Cox regression analyses were performed to explore significant prognostic factors. Results: The 3-year and 5-year OS were respectively 69.7% and 64.0%. The median OS time was 43 months. The 3-year and 5-year EFS were respectively 57.8% and 47.4%. The median EFS time was 34 months. The 5-year OS of the patients with epithelial-derived tumors was better than that of the patients with mesenchymal-derived tumors and malignant melanoma (5-year OS was respectively 72.3%, 47.8% and 30.0%, χ2=36.01, P<0.001). Patients with microscopically margin-negative resection (R0 resection) had the best prognosis, followed by macroscopically margin-negative resection (R1 resection), and debulking surgery was the worst (5-year OS was respectively 78.4%, 55.1% and 37.4%, χ2=24.63, P<0.001). There was no significant difference in 5-year OS between the endoscopic surgery group and the open surgery group (65.8% vs. 53.4%, χ2=2.66, P=0.102). Older patients had worse OS (HR=1.02, P=0.011) and EFS (HR=1.01, P=0.027). Patients receiving adjuvant therapy had a lower risk of death (HR=0.62, P=0.038). Patients with a history of nasal radiotherapy had a higher risk of recurrence (HR=2.48, P=0.002) and a higher risk of death (HR=2.03, P=0.020). Conclusion: For patients with advanced SNM, the efficacy of endoscopic surgery can be comparable to that of open surgery when presence of safe surgical margins, and a treatment plan based on transnasal endoscopic surgery as the main comprehensive treatment is recommended.

Objective: To evaluate the effect of reducing-opioids on postoperative delirium (POD) incidence in elderly patients with gastric cancer surgery. Methods: From July 2016 to September 2021, 130 elderly patients undergoing scheduled gastric cancer surgery in Zhejiang Cancer Hospital were selected and divided into conventional opioid general anesthesia group (group A) and reducing-opioids general anesthesia group (group B) according to random number table. Postoperative analgesic pump formula: group A: 0.2% ropivacaine and 1 µg/ml sufentanil solution; Group B: 0.2% ropivacaine solution. POD assessment was performed once daily between 8 am and 8 pm for 3 days after surgery. The primary outcome measures were POD incidence 3 days after surgery, and the secondary outcome measures included anaesthesia related adverse events 3 days after surgery, such as nausea and vomiting, postoperative fever and fatigue. Results: Among the 130 patients, 7 patients were excluded because they did not comply with the POD test after operation. Finally, 123 elderly patients completed the study. There were 59 cases in group A, aged (73±5) years, including 45 males, and 64 cases in group B, aged (71±6) years, including 56 males. The incidence of total POD 3 days after surgery in group A and B was 30.5% (18/59) and 18.8% (12/64), respectively, with no statistical significance (P>0.05). However, POD incidence at 48 and 72 h after operation in group A [27.1% (16/59) and 16.9% (10/59)] was higher than that in group B [10.9% (8/64) and 4.7% (3/64), both P<0.05]. The incidence of nausea and vomiting in group A was higher than that in group B [15.3% (9/59) vs 1.6% (1/64), P<0.05]. Conclusion: Reducing-opioids consumption have no effect on the incidence of total POD 3 d after gastric cancer surgery in elderly patients, but can reduce the risk of POD 48-72 h after surgery.

Patients with severe alcoholic hepatitis is sensitive to concurrent infection and impact glucocorticoid response and disease prognosis. Glucocorticoids can increase the incidence and of serious infections and fungal infections. Among them, Gram-negative bacterial infections are the major one, and invasive fungal infections are not uncommon. Early diagnosis and empiric anti-infective therapy are important means for severe alcoholic hepatitis with concurrent infection. Anti-infective strategies covering multiple drug-resistant bacteria should be timely formulated after determining the high risk of multiple drug-resistant bacterial infections.

OBJECTIVE: To investigate factors influencing renal functional compensation(RFC) of the preserved kidney after radical nephrectomy (RN). METHODS: A total of 286 patients treated with RN in Peking University People's Hospital were retrospectively analyzed. Preoperative body mass index (BMI), systolic blood pressure (SBP), history of smoking, history of chronic diseases and other basic information, as well as preoperative blood biochemistry, urine routine, imaging examination results were recorded. All the patients underwent 99mtechnetium-diethylenetriamine pentaacetic acid (99mTc-DTPA) renal scans before operation. The surgical method, pathology and blood creatinine values from 1 month to 60 months after RN were recorded. Preoperative and postoperative estimated glomerular filtration rate (eGFR) was calculated by the chronic kidney disease epidemiology collaboration (CKD-EPI) formula. Renal functional compensation was defined as percent change in eGFR of the preserved kidney after RN compared with the preoperative eGFR. Univariate and multivariate regression analyses were used to identify predictive factors of RFC. RESULTS: Median age was 61 years and 65.4% of the patients were male. Early stage (T1 or T2) tumors were found in 83.6% of the cases. 18.5% of the patients had preoperative diabetes mellitus, 39.5% had hypertension, 19.2% had a history of smoking, and 27.6% were found to have renal cyst on the contralateral side. In the study, 226 cases underwent laparoscopic radical nephrectomy and 60 cases underwent open radical nephrectomy. Renal clear cell carcinoma was the most common pathological type, accounting for 88.5%. The median tumor maximum diameter was 4.5 cm (0.7-13.5 cm). Median renal function compensation was 27% one month after radical nephrectomy. Functional stability was then observed to 5 years. The results of univariate analysis showed that age, gender, preoperative blood uric acid, preoperative urine protein, contralateral renal cyst, and percentage of split renal function of contralateral kidney were correlated with RFC (P < 0.05). Among them, UA level and split renal function of contralateral kidney were strongly negatively correlated with RFC. The results of multivariate linear regression analysis showed age (P < 0.001), blood uric acid (P < 0.001), urine protein (P=0.002), preoperative eGFR (P < 0.001) and the split renal function of contralateral kidney (P < 0.001) were independent predictors of RFC. CONCLUSION: The basic examinations, such as blood biochemistry, urine routine and renal scan before RN are of great significance in predicting the compen-satory ability of the preserved kidney after RN, which is supposed to be taken into consideration when making clinical decision.

Objective: To study the efficacy and patient comfort of absorbable hemostatic powder after endoscopic sinus surgery (ESS). Methods: A total of 21 (17 males, 4 females) patients with an average age of 42(ranging from 18 to 65) underwent bilateral ESS for chronic rhinosinusitis(CRS) in Beijing Tongren Hospital, Capital Medical University between October 2015 and July 2019 were enrolled to compare the effect of absorbable hemostasis powder with Nasopore using an intrapatient control design. A randomized controlled trial was conducted in the left and right nasal cavities of the same patient. If hemostatic powder was applied in the experiment nasal cavity, the Nasopore was applied in the control nasal cavity. The mean preoperative sinus computed tomography (CT) score was 6.25. All patients competed for symptom diaries using a visual analog scale (VAS, score out of 10) at baseline, through 1, 7, 14 and 30 days. Outcomes including bleeding, facial pain, nasal obstruction, nasal discharges using VAS were recorded separately for both sides. Postoperative endoscopic scores were also investigated. SPSS 22 and Graphpad prism 8.0 statistical softwares were used for the analysis. Paired t-test or nonparametric test was used between the test side and the control side. The difference was statistically significant (P<0.05). Results: The bleeding score and total nasal symptom VAS scores at postoperative days (POD) 1, 7, 14 and 30 were not significantly different(t=1.341, 0.552, 0.631, 0.158, all P>0.05;t=0.944, 1.471, 1.612, 2.251, all P>0.05). There was no significant difference between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of each nasal symptom VAS scores(all P>0.05). On POD 1, 7 and 14, the packing material degeneration scores of the absorbable hemostasis powder side were significantly lower than those of the Nasopore side [(1.33±0.21)vs(2.00±0.00),(0.38±0.18) vs (1.95±0.22), 0 vs (1.80±0.13), all P<0.01]. There were significant differences between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of endoscopic scores (edema, crusting, discharges, scar, polyps and material degeneration, t=3.07, 7.00, 6.41, 2.69, all P<0.05). Conclusions: The absorbable hemostasis powder and Nasopore has similar postoperative hemostasis effect. The absorbable hemostasis powder is rapidly cleared and without negative effects on mucosal wound healing 14 days postoperatively.
RESUMO
Objective: During laparoscopic pelvic operational procedure for obese patients with rectal cancer, the large amount of fat in the abdominal cavity often impairs the exposure of the surgical field, resulting in technical difficulty. In contrast, robotic surgery has the advantages of being more minimally invasive, precise, and flexible. This study compared the clinical efficacy of robotic and laparoscopic radical resection of rectal cancer for overweight and obese patients. Methods: A retrospective cohort study was conducted. Clinical data of 173 patients with rectal cancer and a body mass index (BMI) ≥ 25 kg/m(2) who received robotic or laparoscopic radical rectal resection at the First Affiliated Hospital of Nanchang University from January 2015 to February 2019 were retrospectively collected. Of 173 patients, 90 underwent robotic surgery and 83 underwent laparoscopic surgery. The intraoperative parameters, postoperative short-term and follow-up status were analyzed and compared between the two groups. The follow-up ended in December 2019. Results: Of 173 patients, 103 were male and 70 were female with a median age of 62 (range 29 to 86) years. The average BMI was (27.2±1.6) kg/m(2) in the robotic group and (27.3±1.5) kg/m(2) in the laparoscopic group. No significant differences in baseline data were observed between two groups (all P>0.05). As compared to the laparoscopic group, the robotic group had less intraoperative blood loss [(73.0±46.8) ml vs. (120.9±59.9) ml, t=-5.881, P<0.001] and higher postoperative hospitalization expense [(61±15) thousand yuan vs (52±13) thousand yuan, t=3.468, P=0.026]. The conversion rate in the robotic group was 1.1% (1/90), which was lower than 6.0% (5/83) in the laparoscopic group, but the difference was not statistically significant (P=0.106). There were no statistically significant differences between the two groups in operative time, number of intraoperative blood transfusion, number of harvested lymph nodes, time to the first flatus, postoperative hospital stay and morbidity of total postoperative complications (all P>0.05). Five (6.0%) patients in the laparoscopic group developed urinary dysfunction, while no case in the robotic group developed postoperative urinary dysfunction (P=0.024). The 173 patients were followed up for 8-59 months, with a median follow-up of 36 months. The 3-year overall survival rate of robotic group and laparoscopic group was 89.8% and 86.6%, respectively without significant difference between the two groups (P=0.638). The 3-year disease-free survival rate of the robotic group and the laparoscopic group was 85.6% and 81.5%, respectively without significant difference as well (P=0.638). Conclusions: Robotic radical surgery is safe and feasible for overweight and obese patients with rectal cancer. Compared with laparoscopic radical surgery, it has advantages of clear vision of surgical exposure, less intraoperative blood loss, less pelvic autonomic nerve damage, and operation in a narrow space.

The purpose of this study was to assess the outcomes of patients with advanced recurrent nasopharyngeal carcinoma (rNPC) and radiation-induced sarcoma of the head and neck (RISHN) who underwent en bloc resection and reconstruction. Fifty-two patients with advanced rNPC (n=36) and RISHN (n=16) underwent en bloc resection and reconstruction with an extended lower vertical trapezius island myocutaneous flap (TIMF). En bloc resection of the tumour (including craniomaxillofacial resections and neck resections) and major defect restoration was successful in all patients. TIMF survival was 92.3%. Postoperative mild hemiplegia occurred in one patient with rNPC. In total, 20 patients (55.5%) in the rNPC group and seven (43.8%) in the RISHN group recovered with no signs of disease at follow-up. No statistically significant difference in recovery status was observed between the rNPC and RISHN groups. En bloc resection of the tumour, including dissection of the carotid artery, ensured microscopic clearance of the disease; this is a viable treatment option for patients with advanced rNPC or RISHN without distant metastasis. The extended vertical lower TIMF is a large, straightforward, and reliable flap for repairing the resultant major defects in the craniomaxillofacial or neck region.

OBJECTIVE: We aimed to observe the changes of cardiac function, cell morphology, cellular repressor of E1A-stimulated genes (CREG) and LC3-II after myocardial infarction (MI) in non-diabetic and diabetic rats, and to explore the relationship between myocardial damage and CREG and autophagy in diabetic rats. MATERIALS AND METHODS: Diabetic rat models were prepared by intraperitoneal injection of low concentration (50 mg/kg) streptozotocin (STZ). MI models were established in normal rats and diabetic rats. The cardiac function of each group was detected by echocardiography. The pathological results of myocardial tissue in the infarcted area were observed under light microscope. The expression of CREG was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Myocardial protein CREG LC3-II expression was measured by Western blot. Autophagy levels were also detected at the cellular level. Construction of CREG overexpressing adenovirus transfected H9c2 cells, and injection of rats with AAV-CREG to achieve the purpose of overexpressing CREG. In vitro and in vivo experiments were conducted to explore the effects of CREG on autophagy and cardiac function in a diabetic MI model. RESULTS: Compared with the non-diabetic sham (NS) group, there were no marked differences in cardiac function and CREG levels in the diabetic sham (DS) group. Compared with the NS group, the cardiac function of the non-diabetic myocardial infarction (NI) group and the diabetic infarction myocardial (DI) group were reduced, and the levels of autophagy were increased. However, the cardiac function of the DI group was worse than that of the NI group, and the autophagy level of the DI group was lower than the NI group. The results at the cellular level were similar to the experiments in vivo. The overexpression of CREG in vivo or in vitro can increase autophagy levels and improve cardiac function. CONCLUSIONS: The exacerbation of myocardial injury after MI in diabetic rats may be related to the inhibition of CREG in myocardial cells of infarcted area by diabetes.

The objective of this study was to explore the clinical significance of perioperative CTCs (circulating tumor cells) counts and EMT-CTCs (epithelial-mesenchymal transition-CTCs) in rectal cancer patients. A total of 30 patients with rectal cancer who underwent radical resection of rectal cancer at the Guangxi Zhuang Autonomous Region People's hospital were enrolled. Five ml peripheral blood was withdrawn from 30 patients with rectal cancer before the operation and seven days after the operation and at the corresponding time also from 20 healthy volunteers. CanPatrol™ CTC detection technique was used to enrich and identify CTCs and IER3 expression simultaneously. We found out that the preoperative total CTCs were correlated with lymph node metastasis (p=0.008) and tumor size, and mixed CTCs were closely correlated with lymph node metastasis (p=0.009). The number of IER3-positive total CTCs and mesenchymal CTCs were statistically associated with tumor size, p=0.034 and 0.043, respectively. The number of CTCs varied significantly before and after the operation in all patients (p=0.049). There were significant differences in CTCs variations between the open operation group and the laparoscopic operation group. In the laparoscopic operation group, the average number of single-cell CTCs was 6.9 before operation and 3.5 after the operation (p=0.013). In the open operation group, the average number of single-cell CTCs was 5.9 before operation and 4.2 after the operation. To conclude, surgery is associated with a decrease of CTCs in rectal cancer patients, especially in patients receiving laparoscopic surgery. The number of CTCs before the operation in rectal cancer patients is related to the size of tumors and regional lymph node metastasis. CTCs detection and characterization may be useful for clinical staging and lymph node dissection during operation.

A 49-year-old woman was admitted to hospital with intermittent dizziness and fatigue for 7 years. The symptoms were aggravated and accompanied by bone pain for more than 4 months. She was referred to our hospital. Laboratory tests and imaging findings suggested that acquired Fanconi Syndrome (FS) was associated with smoldering multiple myeloma (MM). Renal biopsy and electron microscopy confirmed the diagnosis of proximal light chain tubular disease (LCPT). LCPT causes proximal tubular dysfunction, which is characterized by the cytoplasmic crystal deposition usually kappa monoclonal light chain in the proximal tubule. MM with FS and LCPT is less common in clinical practice because it is difficult to diagnose. This is a typical case focusing on the differential diagnosis of monoclonal gammopathy of renal significance(MGRS) such as LCPT and plasma cells diseases.

Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for intestinal disorders. Methods: A retrospectively descriptive cohort study was carried out. Clinical data of 2010 patients who underwent FMT and received follow-up for more than 3 months from May 2014 to November 2018 were collected, including 1,206 cases from Tongji University Shanghai Tenth People's Hospital and 804 cases from Nanjing Eastern Military General Hospital. Of the 2,010 patients, 797 were male and 1,213 were female, with a mean age of (49.4±16.5) years old. Inclusion criteria were those with indications for FMT and voluntary treatment of FMT. Pregnant or lactating women, patients with end-stage disease, cases who were participating or participated in other clinical trials within 3 months, and patients with previous bowel history of pathogen infection, oral antibiotics or proton pump inhibitors (PPI) for the recent2 weeks, and those at immunosuppressive state were excluded. Informed consent was obtained from the enrolled patients and their families. There were 1,356 cases of constipation, 175 cases of inflammatory bowel disease, 148 cases of chronic diarrhea, 127 cases of radiation enteritis, 119 cases of irritable bowel syndrome, and 85 cases of autism (complicating with intestinal disorders). FMT donor requirements: (1) 18 to 30 years old non-relatives, non-pregnant healthy adults with healthy lifestyle and good eating habits as volunteers to participate in fecal donation; (2) no administration of antibiotics within 3 months; (3) no chronic diseases such as constipation, irritable bowel syndrome, inflammatory bowel disease, etc., no autoimmune disease, not in immunosuppressive state, no history of malignant disease; (4) negative pathogen examination of infectious diseases (hepatitis B virus, hepatitis C virus, syphilis, HIV, etc.); (5) negative fecal examination (C.difficile, dysentery bacillus, Shigella, Campylobacter, parasites, etc.). The donor requirements after enrollment: (1) physical examination was reviewed once every two months, and the result still met the above requirements; (2) 16S rRNA sequencing was performed for every fecal donation in order to ensure that the composition and diversity of the fecal flora was stable and reliable. The preparation of the stool suspension referred to the Amsterdam criteria and the preparation process was less than 1 hour. The preparation of the FMT capsule was processed by pre-freezing the stool suspension after the preparation of the above suspension, and the frozen sample was transferred into a freeze dryer for freezing. The dried and lyophilized powder was encapsulated in capsules, and the capsule shell was made of acid-resistant hypromellose capsule (No.0) and pediatric-specific capsule (No.3), sealed and packaged in a-20â refrigerator. Three ways of accepting FMT treatment pathways included 6-day transplantation after the placement of the nasointestinal tube, 6-day oral FMT capsule transplantation and one-time transplantation through colonoscopy. Intestinal preparation (nasointestinal tube feeding of polyethylene glycol until watery stool) was carried out before transplantation.

Meanwhile the clinical cure rates and the clinical improvement rates at 3, 12, and 36 months were 47.7% (714/1 497), 42.8% (425/994), 39.1% (128/327), and 29.1% (436/1 497), 27.0% (268/994), 28.1% (92/327), respectively in the nasointestinal tube group; 38.7% (175/452), 30.2% (91/301), 33.3% (16/48), and 24.3% (110/452), 26.2% (79/301), 25.0% (12/48), respectively in the oral capsule group; 34.4% (21/61), 32.7% (17/52), 18.2% (4/22), and 21.3% (13/61), 13.5% (7/52), 45.5% (10/22), respectively in colonoscopy group. No serious adverse events occurred during treatment and follow-up period. The adverse event of nasointestinal tube group presented higher ratio of discomfort in respiratorytract accounting for 13.1% (196/1497); the oral capsule group had a higher proportion of nausea and vomiting when swallowing capsules accounting for 7.1% (32/452); the colonoscopy group was mainly diarrhea, accounting for 37.7% (23/61). The above symptoms disappeared after the nasointestinal tube was removed, or after treatment ended, or within 1 to 3 days after hospitalization. Conclusion: FMT is a safe and effective method for the treatment of intestinal dysfunction.

OBJECTIVE: To analyze the clinical and pathological features of small renal cell carcinoma (RCC), especially of those with diameter less than 4 cm and to understand the characteristics and factors related to recurrence and progression. METHODS: A total of 200 patients with RCC were stratifiedly selected for retrospective analysis. Their baseline demographic features, tumor-specific clinical features, pathological features of renal lesions, especially microscopic features were collected. The patients were divided according to the largest diameter of renal tumor lesions. Univariate analysis was used to compare the differences between tumor staging and microscopic pathological features between the groups. Binary multivariate Logistic regression was used to investigate factors related to tumor progression and prognosis in the patients with small RCC. RESULTS: The tumor diameters of 127 RCC patients were less than 4 cm and most of them had clear cell renal cell carcinoma (ccRCC). The increase in tumor diameter resulted in significantly higher T stage (P<0.01), higher WHO/International Society of Urological Pathology (ISUP) grade (P<0.05) and increasing chance of lymph node metastasis (P<0.01). Even when the tumor diameter was less than 4 cm, the patients might still have perirenal fat invasion, renal sinus invasion and greater elevated tumor grade (greater than grade 3) and synchronous lung metastasis. The incidences of intravascular thrombus (9.3% vs. 0) and tumor necrosis (27.8% vs. 5.5%) in the patients with RCC between 4-7 cm were significantly higher than those with RCC less than 4 cm (P<0.01). Sub-group analysis of small RCC (less than 4 cm) indicated that the patients with RCC between 2-4 cm were more likely to have intratumoral hemorrhage (44.7% vs. 23%, P<0.05) and necrosis than those with RCC less than 2 cm (8.2% vs. 0, P=0.095). Logistic regression analysis of small RCC showed that the incidence of tumor invasion to renal capsule was higher in ccRCC (OR=5.15, 95%CI: 1.36-19.52). Necrosis was closely related to the formation of peritumor pseudocapsule in small RCC (OR=14.90, 95%CI: 1.41-157.50). Increase in the tumor diameter was related to higher tumor grade (greater than grade 3) (OR=3.49, 95%CI: 1.11- 10.93). CONCLUSION: The tumor stage and grade of small RCC (less than 4 cm) are low, but extra-renal invasion and synchronous distant metastasis may occur. Internal hemorrhage and necrosis in tumor, ccRCC subtype, along with microscopic features, such as the renal capsule invasion and perirenal pseudocapsule formation are relevant factors of malignant behavior of small RCC and could be considered in prognosis evaluation.

BACKGROUND: The correlation between the increased mean platelet volume and varicocele is controversial. OBJECTIVES: We designed this research to demonstrate the correlation relationship between varicocele and mean platelet volume by studying the changes of mean platelet volume in patients with varicocele before and after operation. MATERIALS AND METHODS: A total of 317 patients with left unilateral varicocele underwent operation, and 293 healthy adult males were enrolled in the study. We collected diagnostic data for preoperative patients through physical examination, color Doppler ultrasonography, and blood routine, and recorded the follow-up data at 6 months after operation for varicocele. Platelet indices and the degree of varicocele or the diameter of spermatic vein correlation analysis were performed. Mean platelet volume values of preoperative and 6-month postoperative were statistically evaluated. RESULTS: We found that the degree of varicocele and the diameter of spermatic vein were positively correlated with mean platelet volume (p = 0.001 or p < 0.001). When the left unilateral varicocele patients and healthy subjects were compared, there was a significant increase in mean platelet volume (p = 0.003). Mean platelet volume values of 96 varicocele patients who were cured by operation for varicocele after 6 months were decreased significantly more than preoperative (p = 0.039), but 32 varicocele patients of 6-month postoperative recurrence could not prove this change (p = 0.930). DISCUSSION AND CONCLUSION: Our research proves that mean platelet volume was positively correlated with the degree of varicocele and the diameter of spermatic vein and varicocele patients showed significantly higher mean platelet volume than healthy subjects. The mean platelet volume of varicocele patients cured by operation for varicocele after 6 months was lower than before, but there was no difference in mean platelet volume between 6-month postoperative recurrent patients with preoperative.
