ABSTRACT

Objective:To compare the clinical efficacy of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) in the treatment of incarcerated upper ureteral calculi.Methods:The clinical data of 202 patients with incarcerated upper ureteral calculi treated in our hospital from January 2018 to April 2020 were analyzed retrospectively, including RIRS group treated with RIRS and PCNL group treated with PCNL.There was no significant difference in age [(54.40±11.17) years vs. (52.82±12.58) years], sex [male / female: 86/54 vs. 45/17], body mass index [24.0(21.0, 27.0)kg/m 2 vs. 23.5(20.8, 26.3)kg/m 2], creatinine [75.45 (61.6, 93.3) μmol/L vs. 73.70 (62.4, 93.0) μmol/L], stone stay time [1.0 (0.5, 3.8) months vs. 1.0 (0.5, 6.0) months], stone hardness [(783.60 ±243.55) HU vs. (960.66 ±225.01) HU], stone diameter [(8.65 ±2.95) mm vs. (960.66 ±225.01) mm], stone location (65/75 vs. 34/28), proportion of infection before operation (40/140 vs. 25/62) and history of ESWL treatment (35/140 vs. 13/62) between the two groups. The operation time, hospital stay, perioperative complication rate, hospitalization cost and stone clearance rate were compared between the two groups. The high risk factors of preoperative stone characteristics (stone diameter, stone hardness, previous lithotripsy history, stone incarceration time, degree of hydronephrosis, infection) were scored (yes = 1, no = 0). Cases of complex stones were defined as ≥ 3 points. Simple stone cases were defined as < 3 points. Group analysis was carried out according to the score of stones in order to determine the influence of the choice of surgical methods on the results of operation. Results:All 202 operations were successfully done, and there was no transfer to open surgery or other surgical methods. Compared with the RIRS group, the operation time of the PCNL group was significantly shorter [48.5 (32.0, 62.5) min vs. 63.0 (48.0, 86.0) min, P<0.05], and the stone removal rate was significantly increased [98.4% (61/62) vs. 72.10% (101/ 140), P<0.05], the treatment cost was lower [1.16 (0.80, 1.40) ten thousand yuan vs. 2.73 (2.14, 3.32) ten thousand yuan, P<0.05]. The length of hospital stay in the RIRS group was shorter than that in the PCNL group [3.0 (2.0, 4.0) days vs. 8.0 (6.0, 9.0) days, P<0.05)]. There was no statistical difference in postoperative complications between the two groups [10.7% (15/140)) vs. 12.9% (8/62), P>0.05]. A comparative analysis of high-risk factors affecting stone removal revealed that for simple stone cases, the operation time was lower in the PCNL group than that in RIRS group [50.0(30.0, 64.0)min vs. 62.0(44.5, 86.0)min, P<0.05], the cost was lower [1.18 (0.80, 1.35) ten thousand yuan vs. 2.69 (2.22, 3.32) ten thousand yuan, P<0.05], and the stone removal rate was higher [100% (35/35)vs.78.3% (94/120), P <0.05], but the hospital stay was longer [ 7.0(6.0, 9.0) days vs.3.0(2.0, 4.0) days, P<0.05]. For complex stone cases, the operation time [46.0 (39.0, 61.0) min vs. 65.5 (51.0, 89.8) min, P<0.05] and hospitalization expenses [1.21 (0.98, 1.43) ten thousand yuan vs. 2.73 (2.13, 2.73) ten thousand yuan, P<0.05] in PCNL group were still lower than that in RIRS group, and the stone removal rate [96.3% (26/27)vs. 35% (7/20) , P<0.05] was also significantly higher than the latter. Conclusions:For simple stone cases, PCNL has a higher stone clearance rate, shorter operation time, lower treatment cost, and longer hospital stay than RIRS. For complex stone cases, the PCNL group has a higher stone clearance rate, shorter operation time, lower cost than RIRS group, but the length of hospital stay is no longer statistically different. Therefore, PCNL is more advantageous for the treatment of complex incarcerated upper ureteral calculi.

ABSTRACT

Objective:To understand the current situation of smartphone addiction and mental health of medical freshmen, and conduct research on the relationship between smartphone addiction and mental health, so as to provide evidence for the prevention and intervention of smartphone addiction among medical freshmen.Methods:A stratified random sampling method was used to select 279 freshmen in the medical profession of Binzhou Medical University as the research objects, and the revised smartphone addiction scale (SAS-C) and mental health symptom self-rating checklist scale (SCL-90) were selected for testing. SPSS 19.0 was used for t test. Results:A percentage of 29.71 medical freshmen had smartphone addiction problems, which was generally above average. The SCL-90 total scores and the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility, psychosis and other factors in the smartphone addiction group were significantly higher than those in non-smartphone addiction group. The total score of smartphone addiction in medical professional freshmen was significantly correlated with the total score of SCL-90. In addition to the interference factors of daily life, other factors had positive correlation with various factors of SCL-90. Interpersonal sensitivity and obsessive-compulsive symptoms had a significant predictive effect on smartphone addiction (β=0.24, 0.26, P < 0.01), which were important variables affecting mobile phone addiction of medical freshmen. Conclusion:Many medical freshmen have the problem of smartphone addiction, which may cause a series of psychological problems, especially obsessive-compulsive symptoms, interpersonal sensitivity, anxiety and psychosis.

ABSTRACT

Objective:To investigate the application value of dynamic scintigraphy single-photonemission computed tomography (SPECT) 99m-technetium-galactosyl human serum albumin diethy-lenetriamine pentaacetic ( 99Tc m-GSA) scintigraphy in assessing liver function of perihilar cholangio-carcinoma after portal vein embolization (PVE). Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 16 patients with perihilar cholangiocarcinoma who underwent 99Tc m-GSA scintigraphy after PVE in Beijing Tsinghua Changgung Hospital Affiliated to Tsinghua University from October 2019 to January 2021 were collected. There were 8 males and 8 females, aged from 46 to 78 years, with a median age of 64 years. Observation indicators: (1) liver volume after PVE; (2) liver function after PVE; (3) typical case analysis. Measurement data with normal distribution were represented as Mean± SD. Count data were represented as absolute numbers or percentages. Comparison of data of the same patient was analyzed using the paired t test. Results:(1) Liver volume after PVE:the morphological liver volume and functional liver volume for the 16 patients were (1 420±211)mL and (389±112)mL. The morphological liver volume and functional liver volume were (636±143)mL and (234±106)mL of planning reserved lobe, (784±210)mL and (151±106)mL of planning resection lobe, respectively. The functional liver density (FLD) of planning reserved lobe and planning resection lobe were 0.36±0.12 and 0.19±0.11, showing a significant difference between them ( t=3.794, P<0.05). The planning resection rate of morpholo-gical liver volume and functional liver volume were 37.8%±0.6% and 54.8%±0.2%, showing a significant difference between them ( t=?3.720, P<0.05). (2) Liver function after PVE: 13 of 16 patients completed the indocyanine green (ICG) test, and 3 patients didn't complete the ICG test due to intolerance. For the 13 patients undergoing ICG test, the total ICG-K value was (0.15±0.03)/minutes, and the ICG-K value of planning reserved lobe was (0.07±0.02)/minutes. The total GSA-K value of 16 patients was (0.14±0.10)/minutes, and the GSA-K value of planning reserved lobe was (0.08±0.06)/minutes. (3) Typical case analysis: a 46-year-old male patient with type Bismuth Ⅲa perihilar cholangiocarcinoma was planned to perform perihilar hepatectomy combined with right hepatectomy. The imaging evaluation showed that the volume of reserved liver lobe accounted for 27% of the total liver volume. The serum total bilirubin was 256 μmol/L when admitted and decreased to 118 μmol/L on the day 5 after percutaneous transhepatic biliary drainage. The right anterior and right posterior branches of PVE was performed. SPECT 99Tc m-GSA examination was performed on the day 37 after PVE. The morphological liver volume was 559 mL of planned reserved lobe and 1 461 mL of the whole liver. The planned morphological liver volume resection rate was 61.7%. ICG-K was 0.12/minutes of the whole liver, and 0.04/minutes of planned reserved lobe. The functional liver volume was 134 mL of planned reserved lobe and 309 mL of the whole liver. The planned resection rate of functional liver volume was 56.6%. The GSA-K was 0.20/minutes of the whole liver and 0.09/minutes of planned reserved lobe. R 0 resection was achieved in perihilar hepatectomy combined with right hepatectomy and no liver failure occurred. The survival time of patients was 11 months. Conclusion:Dynamic SPECT 99Tc m-GSA scintigraphy can effectively evaluate the regional function of the reserved liver lobe in patients with perihilar cholangiocarcinoma after PVE.

ABSTRACT

Objective:To investigate the neuroprotective effects of Danggui Shaoyaosan (DSS) on APP<sub>swe</sub>/PS1<sub>ΔE9 </sub>transgenic (APP/PS1) mice and its mechanism related to circular RNA (circRNA). Method:Totally twenty 6-month-old APP/PS1 mice were divided into model group and DSS group, and 10 C57BL/6 wild-type mice were set as the normal control group. The normal group and model group received the same volume of normal saline, and DSS group received drug by gavage administration, all for 8 weeks. The differentially expressed circRNA of APP/PS1 mice before and after DSS intervention was analyzed by circRNA sequencing to construct circRNA-miRNA mRNA interaction network. The results of cricRNA sequencing were then verified by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of phosphoinositide 3-kinase (PI3K), p-PI3K, protein kinase B1 (Akt1), p-Akt1, B lymphocytoma-2 (Bcl-2), and Bcl-2-Associated X protein (Bax) in the hippocampus were detected by immunoblotting (Western blot). The protein expression of Caspase-3 in the hippocampus was detected by immunohistochemistry and the level of apoptosis in the hippocampus was detected by the TUNEL method. Result:Compared with the model group, there were 90 differentially expressed circRNA after intervention with DSS, of which 46 were up-regulated and 44 down-regulated. Compared with the normal group, the expression levels of circRNA1398 and circRNA1399 in the model group decreased, and the expression levels of miR-103-3p, miR-153-3p, miR-143-3p, and miR-143-5p increased. Compared with the model group, the expression levels of circRNA1398 and circRNA1399 in the DSS group were up-regulated, while the expression levels of miR-103-3p, miR-153-3p, miR-143-3p, and miR-143-5p were down-regulated. Compared with the normal group, the expression of p-PI3K, Akt1, p-Akt1, and Bcl-2 in the model group decreased (<italic>P</italic><0.05,<italic> P</italic><0.01), and the expression of Bax and Caspase in the model group increased (<italic>P</italic><0.01). Compared with the model group, the expression of p-PI3K, Akt1, p-Akt1, and Bcl-2 in the hippocampus of the DSS group increased (<italic>P</italic><0.01), and the protein expression of Bax and Caspase decreased (<italic>P</italic><0.01). Compared with the normal group, the apoptosis level in the hippocampus of the model group increased, with an apoptosis rate of (43.76±2.92)%. Compared with the model group, the apoptosis rate of DSS group was (24.64±3.39)%. Conclusion:DSS can activate PI3K/Akt pathway and inhibit apoptosis in hippocampal neurons of APP / PS1 mice, and play a neuroprotective role. The specific mechanism may be related to the regulation of circRNA1398 and circRNA1399 expression and the corresponding miRNA expression.

ABSTRACT

Objective:To investigate the neuroprotective effect of Danggui Shaoyaosan (DSS) in a rat model of amyloid-<italic>β</italic>-peptide<sub>1-42</sub> (A<italic>β</italic><sub>1-42</sub>)-induced Alzheimer's disease (AD) as well as its regulatory effect on NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific protease-1 (Caspase-1) signaling pathway. Method:The AD animal model was established via intracerebral injection of A<italic>β</italic><sub>1-42</sub> and treated with different concentrations of DSS after the division of rats into the sham operation group, model group, as well as the high-, medium-, and low-dose DSS groups. Morris water maze test was conducted to determine the learning and memory abilities of rats. The morphology and function of neurons were detected by hematoxylin-eosin (HE) staining and Golgi staining, followed by immunofluorescence co-localization of NLRP3 inflammasome activation. The mRNA expression levels of interleukin (IL)-1<italic>β</italic> and IL-18 were measured by Real-time polymerase chain reaction (Real-time PCR), and the protein expression levels of NLRP3, Caspase-1, and IL-1<italic>β </italic>were assayed by Western blot. Result:Compared with the sham operation group, the model group exhibited significantly decreased learning and memory abilities (<italic>P</italic><0.01), impaired neuronal morphology and function, up-regulated IL-1<italic>β</italic> and IL-18 mRNA expression, enhanced NLRP3 inflammasome activation, and elevated NLRP3, Caspase-1, and IL-1<italic>β</italic> protein expression (<italic>P</italic><0.01). Compared with the model group, DSS at both medium and high doses remarkably improved the learning and memory abilities of AD rats (<italic>P</italic><0.05, <italic>P</italic><0.01), restored neuronal morphology and function, down-regulated the mRNA expression levels of inflammatory factors IL-1<italic>β</italic> and IL-18, reduced the activation of NLRP3 inflammasomes, and lowered the protein expression levels of NLRP3, Caspase-1, and IL-1<italic>β</italic> (<italic>P</italic><0.01). Conclusion:DSS inhibits inflammasome activation and neuroinflammatory response possibly by regulating the NLRP3/Caspase-1 signaling pathway, thus exerting the neuroprotective effect.

ABSTRACT

OBJECTIVES@#To study the effect of different maintenance doses of caffeine citrate on the success rate of ventilator weaning in very preterm infants (gestational age of ≤32 weeks) with respiratory distress syndrome (RDS).@*METHODS@#A total of 162 preterm infants with RDS who were admitted to the hospital from January 2016 to December 2018 were enrolled in this prospective trial. These infants had a gestational age of ≤32 weeks and required invasive mechanical ventilation. They were randomly divided into a high-dose caffeine group and a low-dose caffeine group, with 81 infants in each group. Within 6 hours after birth, both groups were given caffeine at a dose of 20 mg/kg. After 24 hours, the high- and low-dose caffeine groups were given caffeine at a maintenance dose of 10 mg/kg and 5 mg/kg, respectively. The two groups were compared in terms of re-intubation rate within 48 hours after ventilator weaning, durations of ventilation and oxygen therapy, enteral feeding, weight gain, and the incidence rates of complications and adverse reactions during hospitalization.@*RESULTS@#The high-dose caffeine group had a significantly lower re-intubation rate within 48 hours after ventilator weaning than the low-dose caffeine group (@*CONCLUSIONS@#A high maintenance dose of caffeine can safely and effectively reduce the incidence rate of apnea after ventilator weaning and the failure rate of ventilator weaning in RDS preterm infants with a gestational age of ≤32 weeks, and therefore, it holds promise for clinical application.

ABSTRACT

OBJECTIVE@#To investigate the comparability of the Freelite, Binding Site, Beckman and N Latex FLC, Siemens in the detection of serum free light chain (sFLC) .@*METHODS@#Fifty newly diagnosed multiple myeloma (MM) patients in Tianjin Institute of Blood Research from November 2019 to February 2020 were enrolled. The two systems (Freelite, Binding Site, Beckman and N Latex FLC, Siemens) were used to detect the sFLC of the samples. Outlier detection was performed by ESD method, methodological comparison and deviation assessment were performed by Passing-Bablok regression and Bland-Altman regression.@*RESULTS@#Both the systems could quantitatively analyze free kappa light chain serum samples and free lambda light chain samples. Freelite, Binding Site, Beckman and N Latex FLC, Siemens free light chain test showed FLC-κ:36.5 (6.5, 194), 40.5 (6.94, 288), FLC-λ: 30.1 (4.3, 170.5), 35.1 (2.28, 526), rFLC (FLC-κ/ FLC-λ) : 0.82 (0.05, 43.25), 1.03 (0.03, 32.04), dFLC (|FLC-κ- FLC-λ|) : -5.8 (-161.97, 183.7), 1.1 (-505.1, 279.01), which existed no outliers. There were systematic differences, and the deviation level was not within the clinically acceptable range.@*CONCLUSION@#Both the systems can meet the needs of clinical diagnosis and treatment, but there is a significant deviation between the two systems, the results are not comparable, and should be analyzed separately. In particular, the same system should be selected for monitoring the prognosis of MM.

ABSTRACT

Objective:To study the efficacy of different systemic chemotherapy regimens as first-line and second-line therapy and to determine the prognostic factors for patients with advanced biliary tract cancer.Methods:The clinical data of patients with advanced biliary tract cancer who underwent systemic chemotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2018 were studied. The efficacy of chemotherapy on objective response rate (ORR) and disease control rate (DCR) were evaluated. Potential prognostic factors for survival were studied using the Cox proportional hazards models.Results:Of 151 patients enrolled into this study, there were 75 males and 76 females, with ages ranging from 31 to 77 years (median 58 years). Two treatment protocols were used: (1) 104 patients received a gemcitabine-based regimen (combined with platinums or fluorouracils) or a combination of platinums and fluorouracils, while (2) 47 patients received a combination of albumin-bound paclitaxel and S-1. The corresponding ORR for each group were 15.4%(16/104) and 27.6%(13/47), respectively, and the DCR were 65.4%(68/104) and 72.3%(34/47), respectively. Of 58 evaluable patients who received chemotherapy as a second-line therapy, 31 patients received the regimen containing gemcitabine, platinums or fluorouracils with an ORR of 3.2% (1/31) and a DCR of 35.5%(11/31); a total of 18 patients received the taxanes-based regimen with an ORR of 11.1%(2/18) and a DCR of 38.9%(7/18); 9 patients received the irinotecan-based regimen with an ORR of 22.2%(2/9) and a DCR of 44.4%(4/9). Univariate analysis showed positive liver metastasis and elevated carbohydrate antigen (CA)19-9 level to be significantly correlated with worse survival outcomes ( HR=1.540, 95% CI: 1.019-2.328, P=0.040 and HR=1.892, 95% CI: 1.123-3.188, P=0.017). Conclusion:For patients with advanced biliary tract cancer, in addition to the conventional regimens containing gemcitabine, platinums and fluorouracils, the combination of albumin-bound paclitaxel and S-1 was shown to be an effective chemotherapeutic regimen for these patients. Second-line chemotherapy was insufficient and ineffective, and an irinotecan-based regimen deserves to be further investigated. Liver metastasis and elevated CA19-9 level were worse prognosis after chemotherapy for patients with advanced biliary tract cancer.

ABSTRACT

Objective:To introduce the experience and clinical efficacy of a new type of negative pressure suction ureteroscope in the treatment of upper ureteral calculi, and compare it with traditional rigid ureteroscope and flexible ureteroscope lithotripsy.Methods:From January 2018 to January 2020, 160 patients with upper ureteral incarcerated calculi who were treated in Shengjing Hospital Affiliated to China Medical University were included in this study, and their clinical data were retrospectively analyzed.There were 50 cases in the rigid ureteroscope group, 54 cases in the flexible ureteroscope group and 56 cases in the new negative pressure combined ureteroscope group.The differences of operation time, hospital stay, stone free rate and postoperative complications were observed and compared among the three groups.According to whether the maximum diameter of the stone is more than 1.5 cm, the subgroups were analyzed to further compare the curative effect of the three groups.Results:All the 160 operations were completed successfully and none of them were converted to open surgery.The stone free rate of the new negative pressure suction ureteroscope Group (90.0% (18/20))was higher than that of the flexible ureteroscope Group (61.9% (13/21)) and the rigid ureteroscope Group (55.6% (10/18)), χ 2=8.49, P<0.001). The stone free rate in the first month after operation was also superior (96.4% (54/56), 77.7% (42/54), 74.0% (37/50), χ 2=5.48, P=0.01). The stone subgroup analysis showed that when the stone diameter increased (>1.5 cm), the net stone rate of the new negative pressure suction ureteroscope Group [91.6% (22 / 24)] was better than that of the flexible ureteroscope Group (62.5% (15/24)) and the rigid ureteroscope Group (50.0 (8/16))(χ 2=6.480, P=0.001). Conclusion:Compared with the traditional ureteroscopic lithotripsy, the new negative pressure suction ureteroscopic lithotripsy has higher initial and overall stone free rate, and higher safety factor.For the patients with stone diameter>1.5 cm, the new negative pressure suction ureteroscope lithotripsy has more advantages.

ABSTRACT

@#This study was designed to investigate the therapeutic effect of anti-inflammatory tripeptide KdPT on ophthalmoxerosis. Male BALB/c mice, 8-week old, were treated with 0.2% benzalkonium chloride solution to establish the ophthalmoxerosis model. Four weeks after modeling, the mice were randomly divided into control group, positive group and the low, medium, high dose groups of KdPT. Each group was given normal saline, artificial tears and 1, 10, 100 μg/mL KdPT, respectively. After 3, 5, 7, 10 and 14 days of treatment, the morphology of the eye surface was observed, and the fluorescein sodium staining score was performed. The amount of tear secretion was measured by phenol red cotton thread and the right corneas were taken out for histopathological analysis after 14 days of treatment. Data showed that there was no significant abnormality in general state and the weight of mice in each group at each time point of treatment. After 14 days of treatment, KdPT can promote the secretion of tear, repair the damaged corneal epithelium, and showed a significant therapeutic effect on ophthalmoxerosis in mice. Based on the data, it is possible for KdPT to be developed as a novel drug for ophthalmoxerosis.

ABSTRACT

OBJECTIVE@#To observe the changes of symptoms, Chinese medicine (CM) syndrome, and lung inflammation absorption during convalescence in patients with coronavirus disease 2019 (COVID-19) who had not totally recovered after hospital discharge and whether CM could promote the improvement process.@*METHODS@#This study was designed as a prospective cohort and nested case-control study. A total of 96 eligible patients with COVID-19 in convalescence were enrolled from Beijing Youan Hospital and Beijing Huimin Hospital and followed up from the hospital discharged day. Patients were divided into the CM (64 cases) and the control groups (32 cases) based on the treatment with or without CM and followed up at 14, 28, 56, and 84 days after discharge. In the CM group, patients received the 28-day CM treatment according to two types of CM syndrome. Improvements in clinical symptoms, CM syndrome, and absorption of lung inflammation were observed.@*RESULTS@#All the 96 patients completed the 84-day follow-up from January 21 to March 28, 2020. By the 84th day of follow-up, respiratory symptoms were less than 5%. There was no significant difference in the improvement rates of symptoms, including fatigue, sputum, cough, dry throat, thirst, and upset, between the two groups (P>0.05). Totally 82 patients (85.42%) showed complete lung inflammation absorption at the 84-day follow-up. On day 14, the CM group had a significantly higher absorption rate than the control group (P<0.05) and the relative risk of absorption for CM vs. control group was 3.029 (95% confidence interval: 1.026-8.940). The proportions of CM syndrome types changed with time prolonging: the proportion of the pathogen residue syndrome gradually decreased, and the proportion of both qi and yin deficiency syndrome gradually increased.@*CONCLUSIONS@#Patients with COVID-19 in convalescence had symptoms and lung inflammation after hospital discharge and recovered with time prolonging. CM could improve lung inflammation for early recovery. The types of CM syndrome can be transformed with time prolonging. (Registration No. ChiCTR2000029430).

ABSTRACT

OBJECTIVE@#To evaluate the effect of electro-acupuncture (EA) in infertile patients with phlegm-dampness polycystic ovary syndrome-insulin resistance (PCOS-IR).@*METHODS@#Seventy-six PCOS-IR patients who underwnet in vitro fertilization and embryo transfer (IVF-ET) were equally assigned to two groups according to a random digital table: the EA group and the control group, with 38 cases in each group. Before undergoing IVF, the two groups were treated with EA or pseudo-acupuncture, respectively, for 3 menstrual cycles. The intervention was 25 min twice a week until the day of oocyte collection. The selected acupoints were Zhongwan (RN 12), Tianshu (ST 25), Daheng (SP 15), Daimai (GB 26), Qihai (CV 6), Guanyuan (CV 4), and bilateral points including Xuehai (SP 10), Fenglong (ST 40), Zusanli (ST 36), and Yinlingquan (SP 9). Evaluation of phlegm-dampness syndrome score and IR score were carried out before and after treatment. Additionally, the number of oocytes retrieved, transplantable embryo rate, high-quality embryo rate, clinical pregnancy rate and live birth rate were compared between the two groups. Real-time polymerase chain reaction analysis was used to monitor the mRNA expression of the insulin receptor substrate (IRS-1), phosphatidylinositiol 3-kinase (PI3K) and glucose transport factor 4 (GLUT4) in ovarian granulosa cells.@*RESULTS@#EA treatment reduced the phlegm-dampness syndrome score as well as the IR scores compared with the control group (P0.05). Moreover, the transplantable embryo rate [49.0% (284/580) vs. 41.9% (273/652)], high-quality embryo rate [36.6% (104/284) vs. 27.8% (76/273)], and live birth rate [50% (19/38) vs. 26.3% (10/38)] in the EA group were significantly higher than in the control group (P<0.05). Gene expression analyses revealed significantly elevated IRS-1, PI3K and GLUT4 mRNA in ovarian granulosa cells of the EA group compared with the control group (P<0.05).@*CONCLUSIONS@#EA may ameliorate the effects of phlegm-dampness syndrome and ovarian IR in PCOS-IR patients. Mechanistically, this effect might be through an upregulation of the IRS-1/PI3K/GLUT4 signaling pathway, which may result in improved oocyte quality and embryonic development potential.

ABSTRACT

To tailor the subsequent treatment and follow-up strategy,this study dynamically assessed the response to initial therapy in non-distant metastatic differentiated thyroid cancer (DTC) patients with intermediate and high risk. A total of 184 non-distant metastatic DTC patients (intermediate-risk 111 cases and high-risk 73 cases) were retrospectively enrolled in this study. Based on the results of initial response assessment (6-12 months after initial therapy),patients were divided into two groups:excellent response (ER) group (=113) and non-excellent response (non-ER) group (=71). We compared the differences in clinicopathological features between these 2 groups and evaluated the changes of dynamic response to therapy at the initial and final assessments after initial therapy in all patients. Compared with the ER group,the non-ER group showed a larger tumor size (=2771.500,=0.000),higher proportion of extrathyroidal invasion (=4.070,=0.044),and higher preablative-stimulated thyroglobulin levels (=1367.500,=0.000). ER was achieved in 31% of patients in the initial non-ER group [including indeterminate response (IDR) and biochemical incomplete response (BIR)] at the final follow-up only by thyroid stimulating hormone (TSH) suppression therapy,among which 63.6% were with intermediate risk (especially the patients with IDR) and 36.4% at high risk. In addition,5.2%(6/113) of patients in the initial ER group were reassessed as IDR,BIR,or even structural incomplete response at the end of the follow-up (among which one patient developed into cervical lymph node recurrence,as confirmed by pathology);the TSH level in these patients fluctuated at 0.56-10.35 μIU/ml and was not corrected in time during the follow-up after initial therapy. Some of non-distant metastatic DTC patients with intermediate and high risks who presented initial non-ER may achieve ER only by TSH suppression therapy over time;in contrast,the patients presented initial ER may develop into non-ER without normalized TSH suppression therapy. The dynamic risk assessment system may provide a real-time assessment of recurrence risk and tailor the subsequent treatment and follow-up strategies.

ABSTRACT

From December 2019, the new coronavirus pneumonia (COVID-19) broke out in Wuhan, Hubei, and spread rapidly to the nationwide. On January 20, 2020, the National Health Committee classified COVID-19 pneumonia as one of B class infectious diseases and treated it as class A infectious disease. During the epidemic period, the routine diagnosis and treatment of tumor patients was affected with varying degrees. In this special period, we performed the superiority of the multi-disciplinary team of diagnosis and treatment, achieved accurate diagnosis and treatment of patients with hepatobiliary malignant tumors, provided support for these patients with limited medical resources, and helped them to survive during the epidemic period.On the basis of fully understanding the new coronavirus pneumonia, the treatment strategy should be changed timely during the epidemic, and more appropriate treatment methods should be adopted to minimize the adverse effect of the epidemic on tumor treatment.

ABSTRACT

To investigate the relationship between exposure to famine in fetus and infant period and the risks for hypertension in adulthood. A total of 5 960 participants born between 1956 and 1965 were included in the study and were divided into unexposed group (1963-1965), fetal exposed group (1959-1961), early- childhood exposed group (1956-1958) and transitional group (1962). Logistic regression model was used to explore the association between famine exposure in early life and the risk for hypertension in adulthood. Both the fetal exposure and the early-childhood exposure were the risk factors for hypertension in adulthood (=1.249, 95: 1.049-1.486 and =1.360, 95: 1.102-1.679). Meanwhile, in rural area, compared with unexposed group, the fetal exposure (=1.401, 95: 1.091-1.798) and the early-childhood exposure (=1.460, 95: 1.145-1.862) were also associated with a greater risk of hypertension in adulthood. In addition, fetal exposure and early-childhood exposure to famine in women were associated with 36.0 and 31.9 increased risks for hypertension (95: 7.8-71.7 and 95: 4.8-66.0) according to the stratified analysis. Fetal exposure to famine might increase the risk for hypertension in adulthood.

ABSTRACT

Objective:To observe the preventive effects of infliximab in autoimmune hepatitis (AIH) and to explore its mechanism.Methods:The mice AIH model was established by injecting concanavalin A (Con-A) into the caudal vein. Forty mice were divided into prevention group and control group, with 20 mice in each group. The mice of prevention group were injected intravenously with infliximab (20 mg/kg) one hour before Con-A injection and the mice of control group were administrated with 200 μL phosphate buffered saline (PBS). Serum was collected 3, 8, 12 and 24 h after Con-A/PBS injection. The serum level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) was detected by colorimetry. The level of cytokine interleukin (IL)-6, IL-1β, interferon gamma (IFN-γ), IL-4, IL-17A, IL-10 and chemokine C-X-C motif ligand 10 (CXCL10) was measured by enzyme-linked immunosorbent assay (ELISA). Liver samples were taken 12 h after Con-A/PBS injection for hematoxylin-eosin staining. Liver infiltrated lymphocytes were assessed by flow cytometry. The expression of T-box transcription factor 21 ( TBX21), GATA binding protein 3 ( GATA3), RAR related orphan receptor C ( RORC) and CXCL10 at mRNA level was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of CXCL10 in liver was detected by Western blotting. Paired t test and one-way analysis of variance were used for statistic analysis. Results:At 8, 12, and 24 h after Con-A injection, the serum ALT level, AST level, IL-1β and IFN-γ of prevention group were all lower than those of control group ((545.8±190.3) U/L vs. (865.8±237.7) U/L, (947.6±267.9) U/L vs. (1 448.0±403.5) U/L, (508.6±131.1) U/L vs. (976.6±207.6) U/L; (620.7±132.0) U/L vs. (952.9±106.8) U/L, (801.6±212.0) U/L vs. (1 424.8±236.0) U/L, (632.1±117.8) U/L vs. (1 008.3±187.5) U/L; (31.38±10.12) ng/L vs. (48.12±11.53) ng/L, (39.34±11.40) ng/L vs. (60.00±14.17) ng/L, (29.49±8.22) ng/L vs. (46.89±5.50) ng/L; and (432.93±66.82) ng/L vs. (674.66±97.88) ng/L, (655.09±169.17) ng/L vs. (937.90±166.36) ng/L, (263.40±54.97) ng/L vs. (410.74±86.64) ng/L), and the differences were statistically significant ( t = 2.350, 2.308, 4.263, 4.374, 4.860, 3.806, 2.440, 2.541, 3.939, 4.560, 2.660 and 3.210; all P<0.05). The serum IL-6 levels 3, 8, 12 and 24 h after Con-A injection of prevention group were all lower than those of control group ((1 075.79±303.77) ng/L vs. (1 914.48±317.80) ng/L, (1 945.97±271.85) ng/L vs. (2 100.80±378.42) ng/L, (1 578.60±504.54) ng/L vs. (2 525.40±406.55) ng/L, (1 020.64±280.03) ng/L vs. (1 582.00±311.96) ng/L), and the differences were statistically significant ( t=4.266, 2.903, 3.267 and 2.994; all P < 0.05). At 3 h after Con-A injection, serum CXCL10 level and CXCL10 mRNA expression in liver tissues of prevention group were both lower than those of control group ((1 755.8±148.1) ng/L vs. (2 102.0±334.0) ng/L and 7.20±3.00 vs. 27.60±1.90), and the differences were statistically significant ( t=2.356 and 2.623, both P<0.05). At 3 and 8 h after Con-A injection, T- bet expression at mRNA level in liver tissues of prevention group was lower than that of control group (6.94±2.29 vs. 15.20±3.48 and 9.38±3.48 vs. 18.17±4.48), and the differences were both statistically significant ( t = 4.427 and 3.673, both P<0.05). However, 3, 8, 12 and 24 h after Con-A injection, there were no statistically significant differences in serum IL-4, IL-17A, IL-10, or GATA3 or RORC expression at mRNA level between prevention group and control group (all P > 0.05). Conclusions:Infliximab has certain preventive effects in mice AIH model, which may be achieved by antagonizing TNF-α and decreasing the expression of CXCL10 in liver, reducing the infiltration of T-helper 1 cells and CD8 + T cells into liver, and by reducing T lymphocyte activation induced by inflammatory cytokines thus alleviating the damage of T lymphocytes to hepatocytes.
