BACKGROUND: Autophagy is a homeostatic process for intracellular recycling of bulk proteins and aging organelles. Increased autophagy has now been reported in experimental models of traumatic brain injury, stroke and excitotoxicity, and in patients with Alzheimer's disease and critical illness. The role of autophagy in developmental epilepsy, however, is unknown. The present study was to investigate the effects of recurrent neonatal seizure, in the presence and absence of autophagy inhibitor 3-methyladenine (3-MA), on the acute phase gene expression of ZnTs, LC3 and Beclin-1 in rat cerebral cortex and the interaction among them. METHODS: Thirty-six Sprague-Dawley neonatal rats at postnatal day 6(P6) were randomly divided into three groups: a recurrent-seizures group (RS, n=12), a 3-MA treated-seizure group (3-MA group, each rat pretreated with 3-methyladenine before seizures, 100nmol/ l/day, i.p., n=12) and a control group (n=12). At 1.5 and 6 hours after the last seizures, the mRNA levels of ZnT1-ZnT3, microtubule-associated protein 1A/1B light chain 3 (LC3) and beclin-1 were detected using the real-time RT-PCR method. The LC3 protein level was examined by Western blotting. RESULTS: The levels of LC3, beclin-1 and ZnT-2 transcripts in the RS group elevated significantly at 1.5 and 6 hours after the last seizures compared with those in the control and 3-MA groups. At the interval of 1.5 hours, the mRNA level of ZnT-1 increased significantly after the last seizure compared with that in the control group. There was no significant difference in the transcript levels of ZnT-3 among the three groups. Linear correlation analysis showed that the expression of the five genes in the control group exhibited a significant inter-relationship. In the 3-MA group, however, the inter-relationship was only found between beclin-1 and ZnT-1. In the RS group, the inter-relationship was not observed. CONCLUSIONS: The autophagy/lysosomal pathway is immediately activated along with the elevated expression of ZnT1 and ZnT2 in the cerebral cortex after recurrent seizures. 3-MA is involved in the regulation of the autophagy/lysosomal pathway and ZnTs by down-regulating the expression of LC3 and beclin-1.

Macrophages are involved in many important biological processes and membrane proteins are the key effector molecules for their functions. However, membrane proteins are difficult to analyze by 2-DE based method because of their intrinsic tendency to self-aggregate during the first dimension separation (IEF). To circumvent the obstacle hampering membrane protein analysis, we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique, we identified 458 GO annotated membrane proteins with extremely high confidence, including most known markers of peritoneal macrophages (e.g., CD11b, F4/80, CD14, CD18, CD86, CD44, CD16 and Toll-like receptor). Thirteen other CD antigens and 18 Ras-related small GTPase were also identified. In addition to those known macrophage membrane proteins, a significant number of novel proteins have also been identified. This research provides a valuable data set of macrophage membrane proteins, thus allowing for more comprehensive study of membrane proteins and a better understanding of the function mechanisms of macrophages in many biological processes.

Objective: To investigate the association of Internet gaming disorder (IGD) and sleep quality in adolescents of Xi an, thereby providing theoretical evidence for prevention of IGD and improvement of sleep quality of adolescents. Methods: A total of 1 181 adolescents from 3 middle schools of Xi an were randomly selected between August, 2019 and February, 2020. These adolescents were assessed by a series of questionnaires, including basic information questionnaire, IGD and Insomnia Severity Index (ISI). Univariate analysis and multivariate Logistic regression model were used to evaluate the association between IGD and insomnia. Results: Among 929 junior middle school students who participated in online games and the IGD Diagnostic Questionnaire was filled out in the past 12 months, the prevalence of IGD was 20.0%(186). Univariate analyses indicated that gender,whether single family, whether they living with their parents, whether they were addicted to online games, whether they could control the time of online games, and the severity of insomnia influenced IGD ( χ 2=17.11, 8.33, 202.92, 91.23, 29.06, P <0.05). The multivariate Logistic regression of the total population showed that participating in online games was not associated with the severity of insomnia ( OR = 1.62 , 95% CI =0.92-0.85, P >0.05). The people who participated in online games in the past 12 monthsthe severity of insomnia was positively correlated with the risk of IGD ( OR =3.56，95% CI =1.92-6.61, P <0.01). Conclusion Internet gaming disorder become a severe situation in the middle school students. The severity of insomnia might become the risk factor of IGD, so social should pay more attention to the prevention of internet addiction.

Objective To explore the expression and clinical significance of CCAAT-enhancer-binding proteins (C/EBPα) in colon cancer tissues.Methods The expression level of C/EBPoα in colon cancer tissues and corresponding non-tumor normal tissues of 41 colon cancer patients was detected by Western blot.The correlation between the expression of C/EBPoα and clinicopathological parameters of colon cancer and survival rate of prognosis were statistically analyzed.Results In 41 cases of normal tissue adjacent to carcinoma,low expression of C/EBPeα appeared only 2 cases,high expression 39 cases,low expression rate was only 4.88％;and in 41 cases of colon cancer,C/EBP low expression appeared 32 cases,high expression only 9 cases,low expression rate was 78.05％.Compared with normal adjacent tissues,the expression of C/EBP in colon cancer was down regulated (P＜0.05).In 41 cases of colon cancer,independent of C/EBPα expression and colon cancer,cancer size,sex,age and histological classification of colon cancer clinical pathological parameters (P ＞ 0.05),but tumor node metastasis (TNM) and colon cancer staging was closely related (P ＜ 0.05).The median survival times in low expression and high expression groups were 31.5 and 54.2 months,with significant difference(P ＜0.05).Conclusion The low expression of C/EBPα in colon cancer has a close relationship with TMN staging and survival rate of prognosis,which has a great significance on early diagnosis and targeted therapy of colon cancer in the future.

Objective To investigate the clinical therapeutic effect of biological information infrared liver therapeutic appa-ratus(BILT)combined with praziquantel in the treatment of patients with chronic schistosomiasis. Methods A case-control study was conducted. A total of 142 chronic schistosomiasis patients were divided into an experimental group(BILT combined with praziquantel)with 64 cases and a control group(routine treatment with praziquantel alone)with 78 cases on the basis of the age,gender,disease duration and liver function as paired condition. Fatigue,diarrhea,abdominal distension,liver func-tion,hyaluronic acid(HA)and laminin(LN)were as observation indexes and the observation results were compared between two groups. Results Before the treatment,there were no significant differences between the two groups in the indexes above-mentioned(P>0.05). After the treatment,the incidence rates of fatigue,diarrhea,abdominal distension,abnormal liver func-tion,and the levels of HA and LN in the experimental group were significantly lower than those in the control group(P<0.01). Conclusion BILT combined with praziquantel can significantly alleviate the short-term clinical symptoms,restore liver func-tion and also alleviate hepatic fibrosis of the patients with chronic schistosomiasis.

Objective To investigate the efficacy of telbivudine blocking the spread of hepatitis B virus in intrauterine. Methods Collecting 64 cases of pregnant women who receive treatment in Hangzhou Sixth People's hospital between November 2007-June 2009,which are divided into control group (36 cases)and treatment group (28 eases). Two groups of pregnant women intramuscular HBIG 200IU each one times during pregnancy 28, 32 and 36 weeks. Pregnant women of treatment simultaneously oral telbivudine tabels,600 mg/d. To observe the HBV DNA load and HBsAg levels in newborns of two groups. Results HBsAgpositive rate is 30.56% (11/36) in newborns of the treatment group, which is 7. 14% (2/28) in control group. The difference is statistically significant between two groups ( χ2 = 3. 985, P = 0. 046 ). HBV DNA positive rate is 1 16.67% (6/36) in newborns of control group, which is 0 in treatment group. The difference is statistically significant between two groups ( P ＜ 0.05 ). All pregnant women and newborns do not appear adverse reactions during the treatment. Conclusion HBV blocking rate of treatment group is significantly higher than control group. The results suggest that telbivudine can reduce the risk of HBV vertical transmission to a certain extent.

OBJECTIVETo evaluate the feasibility and reliability of cobas 4800 HPV test for cervical cancer screening and cytology referral.

METHODScobas 4800 HPV test and hybrid capture 2 (HC-2) were used to detect high risk HPV DNA in 670 specimens of liquid-based cytology collected from three hospitals. The agreement between cobas and HC-2 tests was assessed. HPV PCR detection (HybriBio) and gene sequencing were used for genotyping, and the agreement of HPV16 and 18 genotyped by cobas and HybriBio was evaluated. Histological diagnosis was considered as a gold standard to estimate the sensitivity and specificity of cobas vs. HC-2 in detecting CIN2(+) in cervical lesions.

RESULTSThe crude agreement between cobas and HC-2 tests was 89.40%, the Kappa value was 0.778, the positive concordance rate was 86.42%, and the negative concordance rate was 91.36%. The crude agreement rates between cobas and HybriBio on HPV16 and 18 were 88.89% and 94.94%, the Kappa values were 0.777 and 0.753, the positive concordance rates were 98.91% and 100.00%, and the negative concordance rates were 78.41% and 94.44%, respectively. HPV PCR detection (HybriBio) and gene sequencing were considered as adjusted standard: the high risk HPV positive concordance rate was 100%, negative coincidence rate was 94.42%, HPV16 and 18 positive concordance rates were both 100%, and negative concordance rates were 82.35% and 94.44%, respectively. Regarding the detection of CIN2(+), the sensitivity and specificity were 91.07% and 70.97% for cobas, and 93.75% and 71.33% for HC-2, with a non-significant difference between the results of the two tests (P > 0.05).

CONCLUSIONScobas4800 HPV test has good screening sensitivity and specificity in correct detection of HPV16 and 18 and other high-risk HPV virus types.

Objective To determine the acceptance and willingness to pay for breast cancer screening among populations at high risk of breast cancer in urban China. Methods From 2012 to 2014, a cancer screening program in urban China (CanSPUC) was carried out in 13 provinces. The current survey was conducted among participants who were evaluated as having"high?risk for breast cancer"using a Harvard model (community?based) and then underwent breast mammography or ultrasonography screening procedure (hospital-based). The study mainly focused on their acceptance and willingness to pay under certain self?payment assumption for breast cancer screening. Results A total of 3 049 participants, with a mean age of 52.4±7.0 years, were included. The group aged 45 to 55 years accounted for 50% of the patients, and the median annual income per capita in the recent 5 years was 22 000 (15 000-34 000) Chinese yuan (CNY). Educational level, occupation, and marital status may affect their full acceptance and voluntary payment (P<0.05). Of all the participants, 99% (3 016 participants) could totally or substantially accept the breast cancer screening. When the breast cancer screening was assumed to be conducted every 3 years in the low?cost self?paid context, 85% (2 581 participants) of the participants had the willingness to pay, while only 17% were willing to pay >100 CNY. The remaining 15% of the residents showed no willingness to pay, and the unaffordable expenditure (70%, 438 participants) and unnecessary screening (24%, 112 participants) were the primary considerations. Significant differences in acceptance, willingness to pay, and payment were found among the provinces. Conclusion Almost all high?risk populations for breast cancer could accept breast cancer screening. The willingness to pay was relatively high, but the amount of payment was limited and low.

OBJECTIVETo ascertain the causation of a pregnant woman with undefined pneumonia reported from the People's Hospital of Tongling city in Anhui province on November 2005.

METHODSEpidemiological and clinical information of the case was collected from the keypersons close to the case and referring to the medical record. A medical observation was carried out on the close contacts of the case and sick or dead poultry. Tracheal aspirates being collected were tested by both RT-PCR and real-time PCR to detect viral nucleic acids of A/H5N1, and were inoculated into special pathogen free (SPF) embryonated hens' eggs.

RESULTSThe pregnant woman was found to have been contacted with the sick/dead poultry directly on the 4th day before onset of illness. All the 122 close contacts were healthy after a 10-day medical observation. The major clinical features of the case were viral pneumonia with rapidly developed leukopenia and lymphopenia. The progress to acute respiratory distress syndrome and multiple organ dysfunction syndromes was found at clinical presentation. HA and NA gene of A/H5N1 virus were positive. The 8 gene fragments of A/Anhui/1/2005 (H5N1) isolated from the tracheal aspirates had not carried genes from a human virus through reassortment, and the receptor-binding site of the hemagglutinin was polybasic cleavage site.

CONCLUSIONThis was the first documented case of H5N1 infection in pregnant woman. The immunotolerant state of pregnancy might have predisposed to the fatal outcome of the patient.

Objective To estimate the mean annual expenditure of patients with prevalent liver cancer in China on the perspective of the natural progression of the disease and to provide baseline information for liver cancer?related disease burden estimation and evaluation of prevention strategies. Methods A multicenter survey on liver cancer was conducted between 2012 and 2014 in 13 sites where the cancer screening program was conducted in Urban China, by face?to?face interviews with hospitalized patients. Data on basic information, clinical diagnosis and treatment, direct medical expenditure, and direct non?medical expenditure were collected. By?year expenditure and number of visits from the first visit to the end of the survey were analyzed. The trend for the two indicators in each year was analyzed. The subgroup analysis of factors such as sex and age was conducted. All the expenditure data were discounted to the year 2014 and presented in Chinese yuan. The statistical analysis was performed using the SAS 9.4 software. Results A total of 2 222 patients with liver cancer, with a mean age of 55.7±11.2 years, were included. Men accounted for 79.2% (1 759 cases) of the patients, women accounted for 20.8% (463 cases) of the patients, and 75.6% (1 679 cases) of the cases were from cancer hospitals. Stage Ⅰ cases only accounted for 14.1% (299 cases) of all the cases, and most cases were stageⅢorⅣ(62.6%, 1 325 cases). Of the cases, 64.4% (1 430 cases) had pathological information, and 83.6%(1 195 cases) were pathologically hepatocellular carcinoma. The sample sizes for the first 3 years from the first visit were 2 222, 149, and 57, respectively (by?year sample sizes thereafter were<50). The annual total medical expenditures for the first 3 years were 49 091 yuan (95% confidence interval [CI]: 47 376-50 806), 30 506 yuan (95% CI: 26 462-34 549), and 32 100 yuan (95% CI: 25 917-38 283) (P<0.001). The corresponding number of visits were 1.9, 1.6, and 1.5 (P<0.001). The trend for each province was consistent with the overall trend, while the down trend from years 1 to 2 varied among provinces, ranging from 1.4 (Zhejiang province) to 5.6 times (Henan province). For the trend in the first 3 years, differences were found in subgroups such as region (P<0.001) and treatment (P<0.05), instead of sex, age, stage, and other subgroups. Conclusions For liver cancer patients in China, the annual expenditure for the first year in the whole disease course was 1.6 times higher than that for the second year, which varied among provinces. However, information on annual expenditure for the later course of liver cancer is still limited.
