Objective To observe the therapeutic effect of thymopeptide enteric-coated capsules combined with human interferon α2b vaginal effervescent tablets in the treatment of patients with high-risk human papillomavirus(HPV)infection-related cervical lesions and the impact on T lymphocyte subsets.Methods The patients with high-risk HPV infection-related cervical lesions were divided into the treatment group and the control group according to the cohort method.The control group was given human interferon α2b vaginal effervescent tablets 5 × 105 U,once daily,for 2 months.On this basis,the treatment group was treated with thymopeptide enteric-coated capsules at a dose of 30 mg·time-1,three times a day,for 2 months.Therapeutic effects,cervical vaginal microecology indicators[pH values of vaginal secretions,Nugent scores and white blood cell count],T lymphocyte subsets,cytokines[interleukin-4(IL-4),IL-6,IL-10,tumor necrosis factor-α(TNF-α)and interferon-γ(IFN-γ)]were compared between the two groups,and the safety were evaluated.Results Seventy cases in the treatment group and 72 cases in the control group.After treatment,the total effective rate of the treatment group was 94.29％(66 cases/70 cases),which was higher than the control group's 80.56％(58 cases/72 cases),the differences were statistically significant(P＜0.05).After treatment,pH values of vaginal secretions in treatment group and control group were 4.26±0.19 and 4.38±0.17;Nugent scores were(2.53±0.36)and(2.79±0.40)scores;Blood cell count were 5.12±1.14 and 6.03±1.21;CD3+were(69.32±8.10)％and(66.54±7.03)％;CD4+were(37.25±5.03)％and(34.67±4.82)％;CD4+/CD8+were 1.50±0.35 and 1.42±0.33;serum IL-4 levels were(7.49±1.64)and(9.20±2.18)pg·mL-1;serum IL-6 levels were(20.95±5.03)and(26.64±6.22)pg·mL-1;serum IL-10 levels were(11.72±2.46)and(13.43±2.97)pg·mL-1;serum TNF-α levels were(16.48±3.75)and(13.25±2.03)pg·mL-1;serum IFN-γ levels were(13.35±2.11)and(10.93±2.86)pg·mL-1;the differences were statistically significant(all P＜0.05).Adverse drug reactions in the treatment group included nausea,fever,vaginal itching and pain;which in the control group included vaginal itching and pain.The total incidence rates of adverse reactions in the treatment group and the control group were 8.57％(6 cases/70 cases)and 5.56％(4 cases/72 cases),without statistically significant difference(P＞0.05).Conclusion Thymopeptide enteric-coated capsules combined with human interferon α2b vaginal effervescent tablets can improve immune function,reduce inflammatory reactions,and improve cervical and vaginal micro-ecological environment in patients with high-risk HPV infection-related cervical lesions.

Human brain banks use a standardized protocol to collect,process and store post-mortem human brains and related tissues,along with relevant clinical information,and to provide the tissue samples and data as a resource to foster neuroscience research according to a standardized operating protocols(SOP).Human brain bank serves as the foundation for neuroscience research and the diagnosis of neurological disorders,highlighting the crucial rule of ensuring the consistency of standardized quality for brain tissue samples.The first version of SOP in 2017 was published by the China Human Brain Bank Consortium.As members increases from different regions in China,a revised SOP was drafted by experts from the China Human Brain Bank Consortium to meet the growing demands for neuroscience research.The revised SOP places a strong emphasis on ethical standards,incorporates neuropathological evaluation of brain regions,and provides clarity on spinal cord sampling and pathological assessment.Notable enhancements in this updated version of the SOP include reinforced ethical guidelines,inclusion of matching controls in recruitment,and expansion of brain regions to be sampled for neuropathological evaluation.

Polysaccharide from traditional Chinese herb, Saposhnikovia divaricata (Turcz.) Schischk. (SD) was extracted, fractionated and characterized in this work. Four fractions were prepared. Their molecular weight, monosaccharide compositions, linkage modes and structural properties were characterized with SEC-MALS-RI, HPAEC-PAD, GC-MS and NMR. SDP1 was assigned as a 1, 4-α-glucan with small amount of O-6 linked branches. SDP2 contained a big amount of the 1, 4-α-glucan and a small amount of arabinogalactan, while SDP3 possessed relatively lower amount of the 1, 4-α-glucan and a big amount of the arabinogalactan. SDP4 was defined as a pectic arabinogalactan. Four fractions showed antioxidant activities in both molecular and cellular levels and their activity was ranked as SDP4 ≈ SDP3>SDP2>SDP1. The 1, 4-α-glucan in SDP1 had the weakest, while SDP3 and SDP4 showed similar and the highest antioxidant activity. The arabinogalactan was the major component of both SDP3 and SDP4, which significantly contributed to the antioxidant activity of SDP.

OBJECTIVETo assess the clinical feasibility of diagnosing and staging liver fibrosis by apparent diffusion coefficient (ADC).

METHODSTotally, 43 patients (mean age 29.3 years) with chronic hepatitis by liver biopsy and 7 healthy controls (mean age 39.9 years) underwent liver diffusion weighted imaging (DWI) with four b values: 0, 200, 500, and 1000 s/mm2 respectively. The liver fibrosis was staged according to Ishak fibrosis stage. The ADC value of liver fibrosis patients and healthy controls was compared. The correlation of ADC value and liver fibrosis staging was analyzed.

RESULTThe histological staging showed 8 stage 1 patients, 10 stage 2 patients, 6 stage 3 patients, 9 stage 4 patients, 8 stage 5 patients and 2 stage 6 patients. The mean ADC value of liver fibrosis patients was significantly lower than that of healthy controls except for stage 1 group (P < 0.05). There was a negative correlation between liver fibrosis staging and ADC value (r = -0.697 with b=500 s/mm2, P < 0.01). Receiver operating characteristic (ROC) curve of ADC value of advanced liver fibrosis (Ishak stage F3 and higher) showed that area under curve = 0.913, 0.825, and 0.794 with b = 500, 1000, and 200 s/mm2, respectively (95% confidence interval: 83.6%-99.0%, 70.7%-94.3%, 66.5%-92.4%; P < 0.05). When b value was 500 s/mm2, the sensitivity (84%) and specificity (80%) of DWI for diagnosis of advanced liver fibrosis were the highest.

CONCLUSIONDWI is proved to be a useful clinical tool in the quantitative evaluation of liver fibrosis and in the prediction of the process of liver fibrosis with the recommendable b value (500 s/mm2).

OBJECTIVETo understand the prevalence of Epstein-Barr virus (EBV) infection in urban and rural areas of Beijing using the serological method.

METHODSTotally 589 serum samples were collected from children in Beijing urban and rural areas who were 0--14 years old and tested with Viron-Seron ELISA classic EBV virus capsid antigen IgG antibody (EBV VCA IgG) kit. Optical density of serum samples was obtained at the wavelength of 405 nanometers. Sero-positive or negative samples were determined according to standard curve and cut-off attached in ELISA classic EBV VCA IgG kits. The activity of EBV VCA IgG was calculated by using special formula. The percentage and activity of EBV VCA IgG from Beijing children were compared with SPSS 13.0 between the urban and rural areas.

RESULTSThe percentage of EBV VCA IgG seropositive samples was 83.6%, and 80.8% in those from urban and 86.2% in those from rural areas. The peak value of EBV infection was 71% seen among children under the age of 3 years, and in urban area the rate was 67.7%, which was lower than that in the rural area (75.3%), and was 82.5% by the age of 6, which was lower than the data (up to 90%) reported 30 years ago. There was a significant difference in EBV infection rate and VCA IgG activities in children at different ages between urban and rural areas (P < 0.05).

CONCLUSIONThe rate of EBV infection in children living in urban area was lower by the age of 6 years. The primary infection of EBV occurred late in part of children lived in urban area.
