Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.

Objective To evaluate the effect of dexmedetomidine on noise-induced hearing loss in guinea pigs.Methods Twenty-four adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 3 groups (n =8 each) using a random number table:dexmedetomdine group (group D),noise-induced hearing loss group (group N) and dexmedetomidine + noise-induced hearing loss group (group DN).A loading dose of dexmedetomidine 5 μg/kg was infused over 5 min,followed by 135 min of infusion at a rate of 10 μg· kg-1 · h-1.The equal volume of normal saline was infused in group N.Groups N and DN were exposed to noise of 4 kHz center frequency and 118-122 dB SPL for 120 min starting from 20 min of administration.Mean arterial pressure (MAP) and cochlear blood flow (COBF) were recorded before administration and every 5 min during drug administration.The changing rate of COBF was calculated.Arterial blood samples were collected for determination of plasma concentration of noradrenaline (NE) by high performance liquid chromatography at 20 and 140 min of administration.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 and 72 h and 10 days after the end of administration.Results Compared with group N,MAP was significantly decreased,the changing rate of COBF was increased at 5-10 min and 30-140 min of administration,ABR threshold was decreased at 1 and 72 h and 10 days after the end of administration,and the plasma concentration of NE was decreased at 140 min of administration in D + N group (P ＜ 0.05).Conclusion Dexmedetomidine can attenuate noise-induced hearing loss in guinea pigs possibly through inhibiting activation of sympathetic nerves and increasing COBF.

Objective To evaluate the efficacy of intermittent pneumatic compression or sequential compression device in prevention of deep venous thrombosis in long-term bedridden patients.Methods We searched Pubmed (1996～),The Cochrane Library (1997～),CLNAHL (1980～),CNKI (1994～),EM-BASE,Science Direct,Oxford Journals,Wanfang Data(1998 ～),and randomized controlled trials (RCTs) in which IPC or SCD was used as an intervention to prevent DVT,and all the trials were published in English or Chinese.The methodological quality of the included studies was assessed according to the standard of Cochrane systematic review.RevMan 5.0 software was used for Meta-analysis.Results Seven RCTs were included.The results of Meta-analysis showed that the incidence of DVT in the IPC or SCD group was lower than that in the control group.Conclusions IPC or SCD shows an effective tendency in DVT prevention,but because of the low quality and the small sample of the included studies,this conclusion needs to be verified by protocols of more samples and higher quality.

Objective To observe the effect of Zhibo Dihuang Pill(ZDP) on leptin-induced idiopathic central precocious puberty(ICPP) in mice.Methods Eighteen BALB/c female mice aged 18 months were randomized into 6 groups: normal group,model group,high-and low-dose ZDP groups(at the dose of 101.4 and 50.7 g?kg-1?d-1 respectively),and megestrol acetate(3.9 mg?kg-1?d-1)group and gonadotropin releasing hormone analogues(GnRH-A) group(at the first dose of 1573.5 ?g/kg,the second and the third dose of 1180 ?g/kg,once every other day).Except the normal group,the mice in other groups received intraperitoneal injection of leptin 20mg/kg to establish ICPP model.After treatment,the vaginal opening,body weight,uterus weight and ovaries weight as well as the serum levels of luteinizing hormone(LH),estrogen(E2) were detected.Meanwhile,the uterus index and ovaries index were also examined.Results High-dose ZDP had an inhibition on the advance of vaginal opening induced by leptin after modeling for 4~6 days(P0.05).Conclusion The therapeutic effect of ZDP for ICPP is probably related with the inhibition of the advance of hypothalamic-pituitary-gonad axis activation.

AIM:To analyze curative effect of laser treatment for diabetic retinopathy (DR).METHODS:A total of 100 patients (136 eyes) with DR who were admitted to our hospital during January 2015 to December 2016 were enrolled in the study.All patients were given 532nm laser treatment.Changes of visual acuity and the incidence of complications were statistically analyzed after treatment, and the macula central fovea retinal thickness and hemodynamic changes of affected eyes were compared before and after treatment.The effects of laser treatment were compared among patients with different types of diabetes, patients in different DR stages and patients with different glycosylated hemoglobin (HbAlc) levels.RESULTS:After treatment, the macula central fovea retinal thickness, end diastolic velocity (EDV), pulsatility index (PI) and central retinal artery (CRA), mean flow velocity (Vm) significantly decreased (P<0.05).After treatment, there were 2 cases (2 eyes) of bleeding and 2 cases (2 eyes) of tractional retinal detachment.The effective improvement rate of visual acuity was 83.1%.There were significant differences in the improvement rate of visual acuity among patients with different types of diabetes [type 1 (60.0%) vs type 2 (84.9%)], patients in different DR stages [preproliferative diabetic retinopathy (NPDR) 92.3%, early proliferative stage (PDR) 85.1%, high-risk PDR 54.2%] and patients with different HbAlc levels (< 8% 91.8% vs ≥8% 73.0%) (P<0.05).CONCLUSION:The 532nm laser treatment is effective for DR.It can significantly improve the retinal hemodynamics and visual acuity and relieve macular edema.Types of diabetes mellitus, stages of DR and blood glucose control effect may affect the effects of laser treatment.

Objective:To investigate the clinicopathological characteristics and influencing factors of kidney prognosis in primary IgA nephropathy (IgAN) patients.Methods:The data of primary IgAN patients diagnosed with renal biopsy in the First Affiliated Hospital of Anhui Medical University from January 2015 to September 2019 were retrospective analyzed. According to the level of baseline estimated glomerular filtration rate (eGFR) when performing renal biopsy, the patients were divided into group A[eGFR≥90 ml·min -1·(1.73 m 2) -1], group B[eGFR 61-89 ml·min -1·(1.73 m 2) -1] and group C[eGFR≤60 ml·min -1·(1.73 m 2) -1]. The clinical and pathological data were collected and compared among the three groups. Kaplan-Meier method was conducted for renal results, whereas the Cox proportional-hazards regression model was exploited to analyze the influencing factors of kidney prognosis in IgAN patients. Results:A total of 742 patients were included in the study, including 394 cases (53.1%) in group A, 203 cases (27.4%) in group B, and 145 cases (19.5%) in group C. There were 325 males (43.8%) and 417 females (56.2%). The median duration of renal biopsy was 6 (1, 24) months, and the median age was 36 years old (18-68 years old). As the baseline level of renal function decreased, the proportion of patients with nephrotic syndrome, hypertension, anemia and hyperuricemia and the levels of 24 h urinary protein, serum triglyceride and total cholesterol increased significantly (all P<0.05), while the proportion of gross hematuria episodes and the ratio of serum albumin to globulin significantly decreased (all P<0.05). For the aspect of pathological manifestations, the proportions of cell proliferation in capillaries (E1), segmental sclerosis or adhesion (S1), renal tubular atrophy or interstitial fibrosis (T1/2), globular sclerosis, renal arteriole wall thickening and vitreous degeneration, Lee's grade Ⅳ and Ⅴ increased with the decrease of baseline renal function (all P<0.05). Kaplan-Meier analysis showed that the cumulative renal survival rate decreased with the decline of baseline renal function (Log-rank χ2=88.510, P<0.001). As a result of multivariate Cox regression analysis, nephrotic syndrome ( HR=2.399, 95% CI 1.054-5.459, P=0.037), hypertension ( HR=1.806, 95% CI 1.071-3.048, P=0.027), low baseline eGFR (taking group A as the reference, group B: HR=2.383, 95% CI 1.053-5.392, P=0.037; group C: HR=6.878, 95% CI 3.074-15.393, P<0.001), IgG deposition ( HR=2.224, 95% CI 1.384-3.574, P=0.001) and globular sclerosis ( HR=2.075, 95% CI 1.230-3.501, P=0.006) were the independent influencing factors for renal progression in primary IgAN patients. Conclusions:The level of baseline renal function in primary IgAN patients can be used to predict the extent of clinic-pathological damage. Nephrotic syndrome, hypertension, low baseline eGFR, IgG deposition and globular sclerosis are the independent influencing factors for renal progression in primary IgAN patients.
