Bisphenol A (BPA) is a kind of exogenous chemicals presenting in the human living environment widely which affects the action of endocrine hormones in the human body. Numerous studies have shown that BPA has reproductive toxicity in the spermatogenic function damage of the testes through a variety of mechanisms such as interfering with endocrine function, inducing oxidative stress, promoting spermatogonial cell apoptosis, destroying the integrity of the blood-testis barrier, and regulating epigenetic inheritance, thereby destroying male fertility. Relevant studies have shown that TCM can improve male fertility by reversing BPA-induced reproductive damage through multi-component, multi-target and multi-mechanisms. However, there is no systematic review on the mechanism of TCM to reduce the reproductive toxicity of BPA. Based on the existing studies, this article will systematically introduce the mechanisms of BPA-induced reproductive impairment in men and the progress of TCM interventions, with a view to providing reference targets and research directions for the development of new Chinese medicines.

Objective: To study the impact of regional positive lymph node ratio (LNR) on prognosis of patients with gallbladder carcinoma. Methods: The clinicopathological and survival data of 53 patients with gallbladder carcinoma who underwent radical resection with regional lymph node metastasis in Ningbo University Affiliated Lihuili Hospital from May 2012 to December 2020 were collected, and receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of LNR for predicting postoperative survival status in patients with gallbladder carcinoma. According to the critical value, the patients were divided into low LNR group and high LNR group. The clinicopathological features and prognosis of the two groups were compared. Log rank test was used for univariate analysis of prognostic factors in patients with gallbladder carcinoma, and Cox proportional hazards model was used for multivariate analysis. Results: A total of 417 regional lymph nodes were dissected in 53 patients, of which 144 lymph nodes were positive, with a positive rate of 34.5%. The optimal cut-off value of LNR for predicting postoperative survival status of patients with gallbladder carcinoma was 0.33. According to this cut-off value, patients were divided into low LNR group (LNR≤0.33, 28 cases) and high LNR group (LNR>0.33, 25 cases). The recurrence rates were 64.3% (18/28) and 88.0 % (22/25) in low LNR group and high LNR group, respectively. The median recurrence-free survival (RFS) was 8 and 7 months, respectively (P=0.032). In the low LNR group, the 1-, 3-, and 5-year survival rates were 56.2%, 38.4%, and 32.0%, respectively, and the median overall survival (OS) was 16 months. In the high LNR group, the 1-, 3-, and 5-year survival rates were 37.9%, 5.4%, and 0, respectively, and the median OS was 9 months. The postoperative survival rate of patients in the low LNR group was better than that in the high LNR group (P=0.008). Univariate analysis showed that LNR was even associated with RFS and OS in patients with gallbladder carcinoma (P<0.05). Multivariate analysis showed that LNR>0.33 was an independent risk factor for postoperative RFS (HR=1.977, 95% CI: 1.045-3.740), but not for OS (HR=1.561, 95% CI: 0.685-3.553). Conclusion: On the basis of clearing a sufficient number of regional lymph nodes, patients with gallbladder carcinoma with regional LNR>0.33 are more likely to relapse after operation, but the predictive value of LNR>0.33 OS is insufficient.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Objective To identify the disease-causing gene in a Chinese pedigree with familial dilated cardiomyopathy (DCM) by whole-exome sequencing.Methods After collecting the clinical data and extracting the whole blood genomic DNA of the 5 family members form a Chinese DCM pedigree,whole-exome sequencing was performed to search the causative genes.Familial co-segregation analysis among the pedigree was subsequently confirmed by traditional Sanger sequencing.Results We performed whole exome sequencing (WES) on representative affected individuals and unaffected familial members from this pedigree.After comparison with variants identified in affected individuals and unaffected individuals,along with previously reported genetic mutations associated with DCM,we found that a heterozygous variant c.961 C＞T (p.Arg321Ter) in exon 6 of the LMNA gene in affected individuals matched the criteria to be the potential disease-causing gene,which was confirmed by Sanger sequencing.This stop-gain mutation leads to only a small part of LMNA-coding protein expressed,therefore we concluded that LMNA c.961 C＞T should be the causative mutation for this familial DCM case.Conclusions The nonsense mutation c.961 C＞ T in gene LMNA identified by whole-exome sequencing might be the pathogenic mutation in this DCM pedigree.

Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of -0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.

Objectivc To observe the short-term changes of anterior corneal biometry after discontinuation of orthokeratology in patients with 2-year wearing.Methods Retrospective study.Sixty myopic patients aged from 8-14 years old during October 2012 and October 2014 were wearing orthokeratology for 2 years in Tianjin Medical University Eye Hospital.According to the degree of myopia,they are divided into three groups(SE≤-2.00 D for group A,-2.00 D ＜ SE ≤-4.00 D for group B and -4.00 D ＜ SE ≤-6.00 D for group C).The recovery of anterior corneal curvature,including flat K(FK),steep K(SK),average K (AVEK),changes of axial length and central corneal thickness (CCT) at 1 week,2 weeks,1 month after discontinuation of orthokeratology were observed.Results There was no statistical differences in FK,SK,AVEK before and 2 weeks after wearing orthokeratology in group A (all P ＞ 0.05).While in group B,there was no significant difference in FK,SK,AVEK before and 1 month after wearing orthokeratology;There were statistically differences in FK,SK,AVEK at 1 month after discontinuation in group C compared with the baseline (all P ＜0.05).As for CCT,there was no statistical differences among group A,B,C after discontinuation of orthokeratology for 2 weeks (all P ＞ 0.05).There were statistical differences in the axial length between 1 week and 2 weeks after discontinuation of orthokeratology in group B and C (all P ＜ 0.05);There were statistical differences in the axial length between 1 month and 2 weeks after discontinuation of orthokeratology in three groups (all P ＜ 0.05);Compared with the state before wearing orthokeratology,the increase of axial length in group A,B,C were (0.43 ± 0.36) mm,(0.35 ± 0.21)mm and (0.36 ± 0.29) ram,respectively.Conclusion The time course of returning to the original corneal parameter varies among different degree of myopia,and the axial length has no significant growth after short-term discontinuation.

Background:Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course,and available treatments for delaying the progression to end-stage renal disease are limited.This study aimed to assess the efficacy and safety of the traditional Chinese medicine,Niaoduqing particles,for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods:The present study was a prospective,randomized,double-blind,placebo-controlled,multicenter clinical trial.From May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml,min-1· 1.73 m-2,aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces.Patients were randomized in a 1∶1 ratio to either a test group,which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks,or a control group,which was administered a placebo using the same methods.The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment.The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test.The present study reported results based on an intention-to-treat (ITT) analysis.Results:A total of 292 participants underwent the ITT analysis.At 24 weeks,the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the test and control groups,respectively (Z =2.642,P =0.008),and the median change in eGFR was-0.2 (-4.3-2.7) and-2.2 (-5.7-0.8) ml·min-1.1.73 m-2,respectively (Z =-2.408,P =0.016).There were no significant differences in adverse events between the groups.Conclusions:Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD.This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.

This study was aimed to examine the effect of ovariectomy on visceral fat, serum adiponectin levels and lipid profile. Forty-five female Sprague Dawley rats were divided into three groups (n=15 each): ovariectomized group (OVX), ovariectomized plus estrogen-treated group (OVX+E2), and sham-operated group (SHAM). Body weight, abdominal adipose tissues, serum adiponectin and lipid profile were measured and compared among the groups after three-month feeding post-surgery. Significant increases in body weight and visceral fat were found in ovariectomized rats when compared with sham-operated ones and significant increases were also observed in serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in ovariectomized rats. Body weight, visceral fat and serum adiponectin levels were profoundly reduced in OVX+E2 group as compared with OVX group. It was concluded that ovarian hormone deficiency induced by ovariectomy leads to significant increases in body weight and visceral fat, along with increased serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in rats. Attenuation in these changes can be achieved by estrogen supplementation.
