Objective To investigate the association between polymorphism of protein C inhibitor(PCI)gene G10877T and male infertility,and provide theoretical basis for treatment of male infertility.Methods PCR and sequencing technique were applied to detect PCI gene G10877 T polymorphism in 53 normal control and 102 male infertility.Results There were three genotypes of wild type(G/C),hybridization mutation(G/T)and pure mutation(T/T).The analysis of sequencing indicated that in sperums of a proportion of the male infertile patients,TGG in PCI gene G10877T mutated into TGT.The contrast of BLASTB indicated that this mutation made Trp in 271 position change into Cys.Compared with control group,TT genotypic frequency and T allelic frequency in male infertility group had significant differences(P

Objective To observe the effect of Shujinkeli on stroke patients with spastic hemiplegia. Methods The double blind test was applied in this study. 77 stroke patients with spastic hemiplegia were randomly divided into the group A (n=38) and the group B (n=39). Under the guidance of the criterion and routine treatment, patients of the group A were treated with Shujinkeli A and patients of the group B were treated with Shujinkeli B. After treatment, curative effect of patients was evaluated. Results The group A was the treatment group, and the group B was the control group. After treatment, the treatment group was superior to the control group in the improvement of muscular tension, Fugel-Meyer score and Barthel index. Conclusion The Shujinkeli can make the high muscular tension lower, which will accelerate the disabled limbs' recovery and improve patients' motor function and self-care ability of daily life.

Objective:To study the relationship between hepatitis B surface antigen(HBsAg)and the primary liver cancer (PLC).Methods:A 20-year prospective follow-up study was performed continuously in Qidong on a cohort of 515 HBsAg positive male patients aged 20-60 years old.The markers of hepatitis B virus,HBsAg,HBsAb,HBeAg,HBeAb and HBcAb (HBVM 1,2,3,4,5)were detected at the first time of the follow-up.Results:The PLC incidence of the whole cohort was 1340.90/100 000 person years(PY).The middle age of the PLC diagnosis was 43 with an average survival of 15 months.The PLC incidence was significantly higher in 41-50 age group than that of other age groups(P＜0.05).The three major HBVM patterns were 15,135 and 145 in the cohort with percentages of 38.83%(200/515),15.92%(82/515)and 44.08%(227/515)respective1y.The PLC incidences of these three patterns were 1 433.69/100 000 PY,2 284.71/100 000 PY,984.10/100 000 PY respectively,showing a significant difference between 135 and 145(P＜0.01).The percentages of 15,135 and 145 were 39.64%(44/111),23.42%(26/111)and 35.14%(39/111)in PLC patients respectively,showing a significant difference between 15 and 135(P＜0.01).The liver cirrhosis mortality of those three patterns were 195.50/100 000 PY,966.61/100 000 PY and 277.57/100 000 PY respectively,showing the significant differences between 135 and other two patterns(P＜0.01).Conclusion:HBsAg carriers were high risk population of PLC.The regular following-up is helpful on early diagnosis and treatment of PLC in those people,and can prolong the survival time.It was found that 135 had higher PLC risk than other HBVM patterns,suggesting a relationship between HBV duplication and PLC.The anti-virus treatment may delay or remove the occurring of PLC.

OBJECTIVE: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. METHODS: A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). RESULTS: Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. CONCLUSION: The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.

OBJECTIVETo evaluate whether first-degree family history of liver cancer plays a role in liver cancer incidence by prospective evaluation of a patient cohort in Qidong, China over a 20-year period.

METHODSIn May 1992, 708 hepatitis B surface antigen (HBsAg) carriers and 730 HBsAg-negadve controls from Qidong city were enrolled for participation in a prospective cohort study ending in November 2012.Follow-up was carried out every 6 to 12 months, and evaluations included serum assays to measure concentrations of alpha fetoprotein (AFP), HBsAg and alanine aminotransferase (ALT), as well as abdominal ultrasound to assess liver disease.The relationship between baseline (study entry) information of patients with first-degree family history of liver cancer and liver cancer incidence during the two decades of study was statistically assessed.

RESULTSThere were 172 newly diagnosed liver cancer cases in the cohort during 25 753 person-years (py) of follow-up, representing an incidence of 667.88/100 000 py.The incidence rates of liver cancer among participants with or without liver cancer family history were 1 244.36/100 000 py and 509.70/100 000 py respectively, and the between-group difference reached the threshold for statistical significance (P less than 0.01, Relative Risk (RR):2.44, 95% Confidence Interval (CI):1.80-3.31).The incidence rates of liver cancer among participants who had a sibling with liver cancer and participants who had a parent with liver cancer were not significantly different (P > 0.05), but the liver cancer incidence among participants who had a mother with liver cancer was significantly higher than that of participants who had a father with liver cancer (P < 0.05, RR:1.86, 95% CI:1.03-3.36). Among the participants with liver cancer family history, 56.52% (39/69) were diagnosed before 50 years old, and this rate was significantly higher than that of participants without a family history of liver cancer (40.78%, 42/103, P less than 0.05).The incidence rate of liver cancer among the participants who were family history-positive and HBsAg-positive was significantly higher than that of participants who were family history-negative but HBsAg-positive (P < 0.01, RR:1.75, 95% CI:1.29-2.38), and was 59.59 times higher than for participants who were family history-negative and HBsAgnegative.Subgroup analysis of liver cancer incidence among participants who were family history-positive but HBsAg-negative and participants who were family history-negative and HBsAg-negative produced anRR of 2.60, but there was no statistically significant difference between the two subgroups (P > 0.05).At the study's end, the incidence rates of liver cancer for the different subgroups were 32.21% for the family history-positive and HBsAgpositive participants, 19.80% for the family history-negative and HBsAg-positive participants, 1.71% for the family history-positive and HBsAg-negative participants, and 0.65% for the family history-negative and HBsAg-negative participants.

CONCLUSIONFirst-degree family history of liver cancer is a risk factor of liver cancer in Chinese patients from Qidong, and exhibits synergism with HBsAg-positivity for incidence of liver cancer.

Objective:To investigate the gene transcription level changes in the amygdala of social isolation rearing models of schizophrenia to determine the pathogenic genes and their related pathways of schizophrenia.Methods:A total of 29 3-week-old SPF C57BL/6J male mice were randomly divided into control group ( n=16) and model group ( n=13); 4 mice were raised in each transparent mouse cage in the control group, and 1 mouse was raised in each transparent mouse cage in the model group; mice in each cage could see their surrounding mice but could not touch each other. Mice in both groups were fed for 4 weeks and then subjected to open field experiment, pre-pulse inhibition experiment and new object recognition experiment within one week. After the experiment, mice were sacrificed by spinal dislocation, and the amygdala was taken for transcriptome sequencing. The topGO software was used for gene ontology (GO) functional enrichment analysis of differentially expressed genes (DEGs), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed using KEGG database. Results:(1) Animal experiment: compared with the control group, the model group had significantly increased movement distance in the open field experiment ([1 239.20±106.35] m vs. [1 845.53±143.65] m, t=3.464, P=0.002), significantly decreased activity time in the central region 5 min before experiment ([13.15±1.41] s vs. [8.47±1.19]) s, t=2.464, P=0.020). Compared with the control group, the model group had significantly lower percentage of deficient prepulse inhibition (PPI) of 78 dB ([22.28±1.53] % vs. [14.59±2.75] %, t=2.629, P=0.013), and deficient PPI of 88 dB ([32.83±3.39] % vs. [18.44±3.07] %, t=3.081, P=0.005). Compared with the control group, the model group had significantly decreased ratio of time exploring new objects/time exploring former objects ([80.5±2.2]% vs. [71.0±3.6]%, t=2.356, P=0.026). (2) Bioinformatics analysis: a total of 96 DEGs were found, of which 42 were with up-regulated expressions ( Th, Crlf1, etc.), and 54 were with down-regulated expressions ( Prkcd, etc.). Th and Crlf1 were positively correlated ( r=0.940, P=0.018). GO enrichment results suggested that DEGs were enriched in projection function of plasma membrane boundary cells, neuronal differentiation, and cell apoptosis. KEGG enrichment results suggested that DEGs were enriched in WNT signaling pathway, apoptosis pathway and tyrosine metabolism pathway. Protein network interaction analysis suggested that Wnt6, Tcf712, Pitx2, Tcf7 and Cd4 were key proteins. Conclusion:DEGs such as Th, Prkcd, Lrrc74b, Fadd, Wnt6, Ror2, Notum, and Tcf7l2, and their related signaling pathways may be related to schizophrenia in the amygdala of social isolation rearing mice.
