Objective:To approach the effectiveness and safety of traditional Chinese medicine combined with risperidone in the treatment of schizophrenia,and to provide basis for their application in clinic. Methods:The Cochrane,Pubmed,EMBase,CNKI,Wanfang and VIP databases were used to retrieve the randomized controlled trials (RCTs ) and CCTs about traditional Chinese medicine combined with risperidone in the treatment of schizophrenia by computer;and manual retrieval was performed at the same time.The literatures met the standard were collected.The qualities of all the included studies were assessed by Cochrane Handbook and Meta-analysis was performed by use of the RevMan 5.2 software. Results:Fifteen trials and 1 314 patients were included in this review. The qualities of 11 studies were grade C.The Meta-analysis results showed that the clinical effective rate in traditional Chinese medicine combined with risperidone treatment group was higher than that in control group,the difference between two groups was statistically significant (OR= 2.11,95% CI: 1.59 - 2.81,P < 0.01 ).The incidence of adverse drug reactions (insomnia,extrapyramidal symptoms,akathisia)in traditional Chinese medicine combined with risperidone treatment group was lower than that in alone risperidone group, and there were significant differences between two groups (OR=0.25,95%CI:0.17-0.36,P <0.01).Conclusion:Traditional Chinese medicine combined with risperidone is superior to simple application of risperidone in the treatment of schizophrenia,and they can reduce the occurrence of adverse effects of medicine.

Objective To explore the effects and safety of bevacizumab monotherapy on radiationinduced brain necrosis in patients with head and neck cancer.Methods Twenty-three patients with radiation-induced brain necrosis received intravenous injection of bevacizumab 5 mg/kg every 2 weeks for 4 cycles.Before and 2 weeks after the treatment LENT/SOMA scoring system,Montreal Cognitive Assessment (MoCA),and MRI were used to evaluate the scores of subjective and objective items,cognitive scores,and the extent of edema.Adverse effects were observed.Results Two patients suffered from grade 2 rhinorrhagia after the first dose and had to give up the therapy.Twenty-one patients received the full dose of bevacizumab and showed improvement in clinical signs and symptoms.The MoCA score after treatment was significantly higher than that before treatment (t =3.166,P ＜ 0.05).MRI T2-weighted image showed that the volume of brain edema was decreased by (53.9 ± 22.13)％ on average (Z =-5.645,P ＜0.05).One patient showed mild exacerbation of the extent of focus on MRI after the second cycle therapy but still showed significant improvement at the end of four cycles.Of the 21 cases that successfully finished the whole treatment,one suffered from grade 2 rash and one had mild intracranial hemorrhage,however,no grade 3 to 5 adverse reactions were observed.Conclusions Bevacizumab monotherapy may have a rapid and safe therapeutic effect on radiation necrosis.

Objective:To explore the clinical measurements for preventing and curing epistaxis in patients irradiated for nasopharyngeal carcinoma by analyzing the related factors. Methods:Thirty patients irradiated for nasopharyngeal carcinoma and consequently presented epistaxis were retrospectively reviewed by analyzing the clinical characteristics and measurements. Literature review was also performed. Results:Twenty-two cases were successfully rescued, and eight cases died (mortality rate:26.6%). Twenty-five cases underwent inflation sponge packing hemostasis, whereas three cases underwent endoscopic hemostasis with cauterization. Five patients underwent digital subtraction angiography (DSA) and selective arterial embolization. For patients who underwent one irradiation course, the epistaxis latent period ranged from 3 to 12 years, and the amount of bleeding ranged from 200 mL to 1 200 mL. For patients who underwent more than one irradiation course, the epistaxis latent period ranged from 6 months to 3 years, and the amount of bleeding ranged from 300 mL to 8 000 mL. Conclusion:Packing through choanal atresia by using inflation sponge, cautery under endoscopy, DSA, and selective arterial embolization are useful and effective measurements for hemostasis. The epistaxis latent period and volume are related to the age, tumor stage, and ir-radiation course of the patients. Patients with advanced age, tumor stage, and more than one irradiation course have short latent period and high amount of bleeding.

Objective To evaluate the effect of various methods of fecal exfoliated cell testing for screening of colorectal cancer.Methods The stool samples from 814 patients who underwent colonoscopy were collected for fecal exfoliated cell testing using diarrhea feces,twice naturally evacuated feces,magnetic separation or naturally evacuated combined with diarrhea feces.The fecal exfoliated cells were isolated and examined cytologically.The DNA quantitative analysis and gene detection were carried out.Fecal occult blood test was simultaneously performed in twice naturally evacuated feces and naturally evacuated combined with diarrhea feces.Results The sensitivity and specificity of exfoliated cells testing for colorectal Cancer was 66.27%(112 of 169 cases of colorectal cancer)and 99.56%(225 of 226 normal subjects),respectively.There was no correlation of positive rate with differentiations of colorectal cells or Duke's stages(P＞0.05).The nuclear DNA quantitative analysis showed that the sensitivity for detecting cancer was 76.09%for twice naturally evacuated feces and 68.29%for naturally evacuated combined with diarrhea feces,which was superior than diarrhea feces(26.31%)and magnetic separation (43.24%).The positive rate of genes detected in carcinoma tissues concordant with fecal exfoliated cells testing were 83.33%(25/30)for p53,9/10 for APC and 9/10 for K-ras.The sensitivity of cytology was higher than gene detection.The sensitivity of cancer detection was higher in combining exfoliated cells test with fecal occult blood test(93.10%)than exfoliated cells test(73.56%)or fecal occult blood test (80.46%)alone(P＜0.05).Conclusions Fecal exfoliated cells test is an effective method for screening of colorectal cancer.It is the best option for detecting cancer by twice tests of fecal exfoliated cells with liquid-based thin-layer cytological test,and combined with fecal occult blood test.

Objective: To understand the underreporting rate of death among residents in Zhejiang Province from 2016 to 2018, so as to provide a basis for improvement of death surveillance measures. Methods: Multi-stage random cluster sampling was used to select residents in 30 public health surveillance areas of Zhejiang Province and all the residents were investigated the general information and death conditions that occurred during the period 2016-2018 by door to door visit. The underreporting rate of death was calculated and descriptive methods were used to analyze the causes of underreporting deaths. Results: A total of 358 992 residents were investigated in 30 public health surveillance areas of Zhejiang Province. There were 63 underreporting deaths among 5 896 deaths, with an underreporting rate of 1.07%. The underreporting rate in men was 1.30%, which was higher than 0.75% in women ( P<0.05 ). The underreporting rate of residents aged 20 to <40 years was 6.74%, the highest among all the age groups ( P<0.05 ). The underreporting rate was 4.46% on the way to the hospital, the highest among all the places of death ( P<0.05 ). The underreporting rate in Wuxing District of Huzhou was 5.80%, the highest among all the surveillance areas. There were 25 cases of "late report or untimely review", accounting for 39.68%; 38 cases of "not report", accounting for 60.32%, of which 14 cases were caused by doctors forgetting to report, accounting for 22.22%. Conclusion The underreporting rate of death in Zhejiang Province from 2016 to 2018 is generally low. In response to underreporting deaths, multi-departmental collaboration should be promoted to effectively strengthen the reporting and management of routine death surveillance.

Objective To analyze the miss rates of colorectal adenomas during colonoscopy as well as risk factors influencing the adenoma miss rates and to take corresponding measures. Methods A total of 432 patients who underwent index and follow-up colonoscopy in 18 months were randomized and investigated. The results of two colonoscopies were compared and the missed adenomas were defined as the adenomas de-tected only during the second colonoscopy. Miss rates were calculated according to patient-based methods. Chi-square test was used to analyze the relative factors influencing the adenoma miss rate of per-patient. Then the meaningful factors were chosen into the logistic regression model for multiple factors analysis. Results Of 432 patients,116(26. 9%)had missed adenomas on first colonoscopy. Single factor analysis found that the size of adenoma( χ2 = 89. 686,P = 0. 000),the shape of adenoma( χ2 = 68. 488,P = 0. 000),the location of adenoma(χ2 = 77. 055,P = 0. 000)and adenoma tissue types(χ2 = 417. 000,P = 0. 000)were the risk factors for miss rates of colorectal adenomas. Number of polyps(χ2 = 8. 450,P= 0. 038),the organi-zation type of polyp(χ2 = 10. 718,P= 0. 013)and proficiency of colonoscopists(χ2 = 56. 069,P= 0. 000), the quality of bowel preparation(χ2 = 39. 195,P = 0. 000),insertion time(χ2 = 13. 133,P = 0. 001)were also the risk factors for miss rates of colorectal adenomas. Logistic regression analysis showed that the bigger the adenoma size,the less missed adenomas(OR= 0. 341,95%CI:0. 173-0. 671). Also,the longer insertion time took,the lower the adenoma miss rate(OR = 0. 987,95% CI:0. 981-0. 994). Per-patient miss rates were lower for high-risk adenomas compared with low-risk adenomas(OR = 0. 324,95%CI:0. 154-0. 680). Adenomas happening in multiple parts of bowel easily leads to missing(OR= 3. 791,95%CI:1. 505-9. 546). Conclusion The missed diagnosis of adenomas is not only significantly associated with features of missed adenomas,but also with skills of colonoscopists,insertion time,and bowel preparation. The key is high-quality index colonoscopy to avoid adenomas missing.

Objective: To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension. Methods: Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model. Results: Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years. Conclusions Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

Objective:To investigate the current situation of cytomegalovirus (CMV) infection in infants in Lishui, and summarize the related factors of CMV infection, evaluate its influence on the growth and development of infants, and provide evidence for the prevention and control of CMV infection.Methods:In this study, 2 254 cases of infants admitted in pediatric ward in Lishui Maternal and Child Health Hospital, Qingtian County People′s Hospital, Suichang County People′s Hospital, Qingyuan County People′s Hospital from January 1, 2015 to December 31, 2017 with integral clinical data were selected. All the babies were followed up from the time when they were born to 1 year old. The serum CMV antibody and the urine CMV-DNA were screened, the general situation and clinical features of CMV infection were summarized, and the relevant factors of infants CMV infection were analyzed and screened by the single factor and multiple factors analysis. They were followed up to 1 year old to clarify the influence of CMV infection on the growth and development of infants.Results:From 2015 to 2017, the total positive infection rate of CMV-IgM in infants under 1 year old in Lishui was 10.43%(235/2 254), and CMV-IgM positive infection decreased year by year. The positive rate of CMV-IgG did not change significantly with time. The positive rate of CMV-IgM was the highest at 1—3 months, and up to 15.29% (61/399). The positive rate of CMV-IgM decreased with the age of the babies. The positive rate of CMV-IgG increased with the age of the babies. The positive rate of CMV-IgM in infants showed no significant difference in gender ( P>0.05). The positive rate of CMV-IgM was higher in men than that in women [65.43% (810/1 238) vs. 55.51% (564/1 016)], and there was significant difference ( P<0.05). The gestational age of the infected group was lower than that of the non-infected group [(37.41 ± 1.63) weeks vs. (38.97 ± 0.97) weeks], and the breast-feeding rate of the infected group was higher than that of the non-infected group [57.87%(136/235) vs. 40.00%(40/100)], and there were significant differences ( P<0.05). Thrombocytopenia, the increase of transaminase, necrotizing enterocolitis of newborn, and hepatosplenomegaly of infected group is higher that of the non-infected group [18.72%(44/235) vs. 1.00% (1/100), 29.36% (69/235) vs. 13.00% (13/100), 26.81% (63/235) vs. 10.00% (10/100), 9.79% (23/235) vs. 0], and there were significant differences ( P<0.05). Gestational age and breast-feeding were possible risk factors for CMV infection in infants under 1 year old ( P<0.05). There was no significant difference in height, weight, head circumference and intelligence score between the infected group and the non-infected group at the age of 1 year ( P>0.05). The total abnormal rate of hearing development and the abnormal detection rate of B-ultrasound in the infected group were higher than those in the non-infected group [13.62%(64/470) vs. 1.00%(2/200), 6.38%(15/235) vs. 0], and there were significant differences ( P<0.05). Conclusions:The CMV active infection rate of infants under 1 year old in Lishui is relatively high and decreases year by year. It decreases with the prolongation of birth time, and there is no gender difference. Gestational age and breast-feeding are the risk factors for active CMV infection in infants. CMV infection affects the hearing development and the brain development of infants under 1 year old, which is the main cause of hepatitis. It is necessary to pay attention to the prevention of CMV infection, strengthen maternal perinatal health care, and strengthen the screening of CMV infection in high-risk groups.
