Objective:This study aims to evaluate the clinical efficacy and safety of Dibai Yijing Formula(DYF)in the treat-ment of male infertility with essence deficiency in the kidney and damp-heat in the essence chamber(Abbreviation:kidney deficiency and damp-heat type).Methods:This study employed a randomized,controlled clinical trial design,recruiting 72 male patients with infertility due to kidney deficiency and damp-heat type.Patients were randomly assigned to an treatment group(36 patients)and a control group(36 patients)using a random number table.The control group received oral Clomiphene Citrate Capsules(50 mg,twice daily),while the treatment group received oral DYF(one dose daily,200 ml each time,30 minutes after breakfast and dinner).Both groups underwent a 12-week treatment period.After treatment,sperm concentration(SC),percentage of progressively motile sperms(PR),total sperm motility[PR+percentage of non-progressively motile sperms(NP)],and semen volume(SV)were compared between the two groups before and after treatment.Additionally,the total score of Traditional Chinese Medicine(TCM)syndrome score and sperm DNA fragmentation index(DFI)and pregnancy outcomes of the patients'spouses were compared between the two groups.Results:Three patients dropped out from the treatment group and four from the control group.There were no statistically sig-nificant differences in semen parameters between the two groups(P＞0.05).After treatment,the patients in the treatment group showed significant difference in the percentage of SC([19.42±5.30]x 106/ml vs[10.75±2.41]x 106/ml),PR([27.72±6.62]％vs[20.04±4.10]％),PR+NP([49.86±10.68]％vs(33.74±5.58)％],DFI([12.33±3.43]％vs[15.06±3.98]％)and TCM symtom score([7.45±1.82]vs[13.85±1.91]),and the difference was statistically significant(P＜0.05).The patients in the control group showed significant difference in the percentage of SC([19.56±5.24]× 106/ml vs[11.31±2.08]× 106/ml)and TCM symptom score([12.81±1.86]vs[14.06±1.64]).But no significant changes were observed in the PR([21.75±5.93]％vs[20.05±4.67]％),PR+NP([34.23±7.15]％vs[32.35±4.09]％),SV([3.19±1.08]ml vs[3.12±1.13]ml),and DFI([15.11±4.76]％vs[15.51±4.35]％)were not statistically significant(P＞0.05).Improve-ments in PR,PR+NP,TCM symptom score and DFI in the treatment group were better than those in the control group after treatment(P＜0.05);the differences in SC and SV and spousal pregnancy in the treatment group were not statistically significant compared with those in the control group(P＞0.05).No serious adverse events occurred in both groups during the treatment period.Conclusion:The treatment of male infertility with DYF is effective and safe.

Objective:To explore the current status of the quality of life of children with disabilities and its influencing factors. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 285 family caregivers of children with disabilities were enrolled in Shanghai. The EuroQol-5 Dimension Questionnaire Youth Version (EQ-5D-Y) was used to measure the quality of life of 285 children with disabilities. The impact of individual factors, caregiver factors, and environmental factors (family factors and social factors) on children's quality of life were analyzed using multiple linear stepwise regression analysis. Results:The score of Visual Analog Scale (VAS) was (71.66±22.33). The quality of life were poorer for children with physical disabilities (B = -13.623, 95%CI -25.282 to -1.965, P = 0.022) or multiple disabilities (B = -14.911, 95%CI -27.445 to -2.377, P = 0.020), combined diseases (B = -8.995, 95%CI -14.780 to -3.210, P = 0.002), emotional instability (B = -4.414, 95%CI -7.433 to -1.395, P = 0.004), poor partnerships (B = 4.965, 95%CI 1.748 to 8.181, P = 0.003), no pre-school education (B = -7.757, 95%CI -12.954 to -2.561, P = 0.004) and grandparents as the main caregiver (B = -7.999, 95%CI -14.288 to -1.710, P = 0.013). Conclusion:The quality of life for children with disabilities is relatively poor and influenced by multiple factors such as children's individual, caregivers, and environment. The main influencing factors are individual factors and caregiver factors.

Objective:To explore the nutritional status and influencing factors among children with disabilities in developed areas. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 480 caregivers of children with disabilities aged two to 18 years in Shanghai were investigated their heights and weights, and the body mass index (BMI) was calculated. The influencing factors were analyzed from the dimensions of children's personal, family and social characteristics based on the Ecological System Theory. Chi-square test and binary Logistic regression model were used to analyze the influencing factors associated with the nutritional status of children with disabilities. Results:The prevalence of thinness, overweight and obesity in 480 children was 23.75%, 13.54% and 13.33%, respectively. Multivariate Logistic regression analysis showed that potato intake (OR = 0.420, 95%CI 0.197 to 0.893, P < 0.05) and caregivers' perception of child's weight (OR _underweight = 4.188, 95%CI 1.488 to 11.787, P < 0.01) were associated with children's thinness. Types of disability (OR _autism= 0.142, 95%CI 0.034 to 0.591, P < 0.01), the role of caregiver (OR _father= 5.519, 95%CI 1.110 to 27.440, P < 0.05), and caregivers' perception of the child's weight (OR _overweight = 5.669, 95%CI 1.112 to 28.903, P < 0.05) were associated with children's overweight/obesity. Conclusion:The prevalence of malnutrition among children with disabilities in Shanghai is higher than those typically-developing, especially thinness and obesity. The nutritional status is greatly affected by the type of disability, dietary intake and family characteristics.

Objective:To explore the quality of life of caregivers of children with disabilities and its influencing factors. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 496 family caregivers of children with disabilities were surveyed in Shanghai. The 12-item Short-form Health Survey (SF-12) was used to measure the quality of life of 496 caregivers, and multiple linear regression was performed to analyze the related factors. Results:The score of physical component summary (PCS) of caregivers was (51.67±8.11), and the score of mental component summary (MCS) was (42.10±12.66). The scores of PCS were lower in caregivers with children aged 6 to 18 years (B = -1.783, 95%CI -3.279 to -0.287, P = 0.020), children with emotional instability (B = 2.719, 95%CI 1.254 to 4.184, P < 0.001), female caregivers (B = -3.765, 95%CI -6.578 to -0.953, P = 0.009), and caregivers who were relatively dissatisfied with the policy (B = 1.973, 95%CI 0.367 to 3.578, P = 0.016); and were higher in caregivers with children with speech disabilities (B = 3.463, 95%CI 0.053 to 6.873, P = 0.047). The types of disabilities of children (B_hearing = 9.465, 95%CI 5.107 to 13.823, P < 0.001; B_undetermined = 5.999, 95%CI 1.558 to 10.441, P = 0.008), playmates of children (B = 2.626, 95%CI 0.352 to 4.901, P = 0.024), education level of caregivers (B_{high middle school} = -4.701, 95%CI -8.028 to -1.374, P = 0.006; B_{high school} = -3.610, 95%CI -6.604 to -0.615, P = 0.018), family size (B = 2.616, 95%CI 0.479 to 4.753, P = 0.017) and per capita monthly income (B _{< 5000 Yuan}= -6.572, 95%CI -9.136 to -4.008, P < 0.001; B_{5000 to < 10000 Yuan} = -4.932, 95%CI -7.544 to -2.319, P < 0.001) were associated with the scores of MCS. Conclusion:The quality of life, especially the mental health, of caregivers of children with disabilities is poor. The influencing factors cover multiple dimensions such as caregivers, children, family and social environment.

Objective:To investigate the depression status of caregivers of children with disabilities and analyze the influencing factors. Methods:From August to September, 2020, a one-to-one interview was conducted using a convenience sampling method to determine the depression status of 334 caregivers of children with disabilities in Shanghai. Patient Health Questionnaire 9 Item (PHQ-9) was used to evaluate the depression status. The data were analyzed with univariate analysis from three aspects: caregiver, care recipient and environment. Then, the statistically significant variables were included in a dichotomous logistic regression. Results:The depression rate of 334 caregivers of children with disabilities was 35.9%. Among the caregiver factors, female caregivers had a higher risk of depression than male (OR = 2.193, 95%CI 1.131 to 4.254, P = 0.002). Among the care recipient factors, poor sleep quality (OR = 1.942, 5%CI 1.113 to 3.386, P < 0.05), emotional instability (OR = 17.456, 95%CI 2.534 to 120.240, P < 0.05) and types of disability (OR_intelligence = 5.401, 95%CI 1.995 to 14.624; OR_mental = 3.712, 95%CI 1.615 to 8.530; OR_physical = 2.913, 95%CI 1.330 to 6.379; P < 0.05) were associated with the depression of caregivers. Among the environmental factors, caregivers in rented housing had a higher risk of depression than those in owner-occupied housing (OR = 1.727, 95%CI 1.135 to 2.627, P < 0.05). Conclusion:The depression status of caregivers of children with disabilities is not optimistic, with higher rates of reported depression among female caregivers, caregivers in rented housing; caregivers of children with intellectual, mental and physical disabilities, and poor sleep quality and emotional instability.

To analyze the clinical features and prognosis of ulcerative colitis(UC)complicated with acute massive lower gastrointestinal bleeding(LGIB). Methods Eleven patients hospitalized in Peking Union Medical College Hospital from January 2006 to December 2017 for treatment of UC,suffering from acute massive LGIB,were enrolled and descriptively analyzed. Results The proportion of UC patients with acute massive LGIB was 0.7% among all 1486 UC patients hospitalized during the study period.The disease was moderately or severely active in these 11 patients,among whom 9 patients(81.8%)had chronic relapsing pancolitis.Cytomegalovirus infection was present in 5 patients,among whom 4 patients received antiviral treatments.All the 11 patients received treatments including food and water fasting,rehydration,blood transfusion,and use of somatostatin.Four patients received emergency surgical treatment after the first episode of massive bleeding,and 3 of them suffered from re-bleeding after the surgery.Among the remaining seven patients,two underwent emergency total colectomy+subtotal rectectomy+ileostomy and three received elective total resection of colon and rectum or total colectomy+subtotal rectectomy+ileostomy.Thus,9 patients underwent emergency surgery,1 patient did not receive surgey during follow-up,and 1 patient was lost to follow-up. Conclusions Acute massive LGIB is a manifestation of active UC and can be associated with poor prognosis.Optimized perioperative management is important for improving the outcomes of such patients.

OBJECTIVES: To study the urinary metabolic profile in rats with deep venous thrombosis （DVT） based on metabolomics and to screen out small molecular biomarkers for the diagnosis and forensic identification of DVT. METHODS: Inferior vena cava of rats was ligated to construct DVT models. The rats were randomly divided into three groups： DVT, sham, and control groups, 10 in each group. The urine of DVT and sham rats was collected during 24 hours in the metabolic cage at 48 hours after operating, meanwhile, 24 hours urine was collected in control group. The metabolic profile was analyzed by nuclear magnetic resonance. SIMCA-P 14.1 software was used for pattern recognition. The variable importance in projection （VIP） value from orthogonal PLS-DA （OPLS-DA） model combined with Mann-Whitney U test were used to search the different metabolites in the urine. RESULTS: The metabolic profiles of urine from DVT, sham, and control groups had significant differences. The DVT, sham, and control groups could be distinguished by the partial least squares method-discriminant analysis （PLS-DA） model. Compared with the urine of the rats in control groups, the levels of leucine, glutamine, creatine, creatinine and sucrose in the urine of DVT rats were up-regulated, and the levels of 3-hydroxybutyrate, lactate, acetone, α-oxoglutarate, citrate and hippurate were down-regulated. CONCLUSIONS The different metabolites in the urine of DVT rats are expected to become its candidate biomarkers. The results can provide a research basis for the diagnosis, treatment and forensic identification of DVT.

This report presents the endemic status of schistosomiasis in the People's Republic of China at national level in 2016,and analyzes the data collected from the national schistosomiasis prevention and control system and 454 national schisto-somiasis surveillance sites. Among the 12 provinces(municipality and autonomous region)of endemic of schistosomiasis japoni-ca in P. R. China,5 provinces (municipality and autonomous region),i. e.,Shanghai,Zhejiang,Fujian,Guangdong and Guangxi,had achieved elimination,and 7 provinces of Sichuan,Yunnan,Jiangsu,Hubei,Anhui,Jiangxi and Hunan had achieved transmission control by the end of 2016. There are 451 endemic counties(cities,districts)covering 257 million peo-ple,specifically including 29692 endemic villages of 69.39 million people at risk. Among the 451 endemic counties(cities,dis-tricts),35.25％(159/451),42.35％(191/451)and 22.39％(101/451)reached the criteria of elimination,transmission inter-ruption and transmission control,respectively in 2016. By the end of 2016,it was estimated of 54454 infections of schistosome, decreased by 29.46％compared with 77194 in 2015. No acute schistosomiasis case was reported in 2016. There were 30573 ad-vanced schistosomiasis cases documented in 2016. A total of 8500710 individuals received schistosomiasis examinations and 600 individuals were parasitologically diagnosed,decreased by 83.36％compared with 3606 in 2015. The Oncomelania hupen-sis snail survey was performed in 22140 endemic villages and O. hupensis snails were found in 7106 villages,accounting for 32.109％of the total villages,with 20 newly detected villages with snails. The snail survey covered area of 813963.91 hm2 and snails were found in an area of 235096.04 hm2,including a newly detected area of 1346.48 hm2. No schistosome-infected snails were found in 2016. A total of 881050 bovines were raised in the schistosomiasis endemic area. Of them,510468 bovines re-ceived examinations,resulting in 8 schistosome-infected bovines. There were 147642 schistosomiasis cases receiving drug treat-ment in 2016,with 2303555 individuals undergoing expanded chemotherapy;there were 9 bovines with schistosomiasis receiv-ing drug treatment,with 439857 bovines undergoing expanded chemotherapy;a total of 139483.84 hm2 area with snail control by using molluscicides,with actual molluscicide-treated area of 73941.75 hm2;and 3101.52 hm2 snail habitants were treated by environmental modification. Based on the data from the 454 national schistosomiasis surveillance sites,the mean Schistosoma japonicum infection rate was 0.02％ and 0.0078％ in humans and bovines,respectively. No schistosome-infected snails were found in all the surveillance sites. The results demonstrate a decline in the endemicity of schistosomiasis in P. R. China com-pared with the level of 2015. However,the distribution area of snails in China is still large and the infection source of schistoso-miasis still exists to some extent in some endemic areas;in some regions,the task to reach the standard of transmission interrup-tion is still arduous. There are still objective factors of epidemic and transmission and risk factors of endemic reversal and re-bound for schistosomiasis. So,further control and effective surveillance as well as accurate prevention and control should be im-plemented to promote the elimination process on schistosomiasis in P. R. China.

To enhance the quality and efficiency of ozagrel by investigating the differences between the ozagrel polymorphs in bioavailability. Solid ozagrel in different polymorph forms were orally administered to SD rats. An HPLC method was established to determinate plasma level of ozagrel. The bioavailabilities of two polymorph forms were calculated and compared. The pharmacokinetic parameters of ozagrel, were as follows: Cmax was 32.72 ± 17.04 and 34.01 ± 19.13 mg · L(-1), respectively; AUC0-t was 61.14 ± 14.76 and 85.56 ± 18.08 mg · L(-1) · h, respectively; t½ was 1.53 ± 0.51 and 4.73 ± 3.00 h, respectively. There was no significant difference in pharmacokinetic parameters between form I and II polymorphs of ozagrel while the t½ of form II is longer, which indicates that the use of form II polymorph as pharmaceutical product may prolong the effective action time in clinics. This would help the polymorph quality control in drug production.

OBJECTIVETo evaluate the clinical results of using end plate rings in preventing subsidence of titanium cage in anterior cervical corpectomy and fusion (ACCF) surgery.

METHODSThe clinical data of 71 patients with cervical spondylotic myelopathy underwent ACCF in single segment from February 2008 to February 2011 were retrospectively analyzed. There were 38 males and 33 females, aged from 39 to 74 years old with a mean of 53.8 years. Thirty-three were used end plate rings and thirty-eight were not used (end plate rings group and no end plate ring group, respectively). The Japanese Orthopaedic Association (JOA) score, Odom's scale, imaging data were used to evaluate the clinical effects. Imaging data including Cobb angle of fusion segment, intervertebral height of anterior border (Da) and posterior border (Dp), the mean intervertebral height (Dm).

RESULTSAll patients were followed up from 13 to 34 months with an average of 19.5 months. Between two groups, there was no significant difference in Cobb angle of fusion segment and the mean intervertebral height (Dm) before surgery and one week after surgery. Whereas, one year after surgery, the Cobb angle of end plate ring group was (9.4 ± 3.8) degrees, and contral group was (7.5 ± 3.9) degrees, which was significantly lower than that of end plate ring group. Meanwhile, the Dm of end plate ring group was (57.3 ± 2.2) mm, and no end ring group was (55.2 ± 2.6) mm which was significantly lower than that of end plate ring group. The subsidence in end plate ring group was 57.6%, and was 78.9% in no end plate ring group. There was no significant difference in JOA score before and after surgery between two groups. At 1 year after operation, 90.9% (30/33) got excellent or good results in end plate ring group, 89.5% (33/38) got excellent or good results in contral group.

CONCLUSIONThe use of end plate rings could not completely prevent the subsidence of titanium cage, however, which can decrease the occurrence rate of the subsidence and lessen its degree.
