Epilepsy is a complications of brain injury or stroke,and is a common diseases in reha-bilitation or neurology department.Transcranial magnetic stimulation as a classical treatment means for stroke or brain injury,but also can promote the recovery of epilepsy.However,there is no clear clinical re-port for safety of epilepsy patients use both donepezil and transcranial magnetic stimulation .The article re-views the literature.Clinicians maybe provided some help.

OBJECTIVETo investigate the association of heptitis B virus (HBV) genotypes and precore(PreC)/basal core promoter(BCP) mutation with interruption failure of HBV vaccination in mother-to-infant transmission.

METHODSA total number of 208 serum samples were collected from infants and mothers,including 16 infants who had become HBsAg-positive despite a complete and timely course of immunization and another 88 infants successfully protected from mother-to infant HBV transmission. HBV genotypes were determined by type-specific primers PCR method. PreC/BCP mutations were detected by direct sequencing of PCR products, and Clustal W 1.8 software was applied to analyzing the sequences.

RESULTSOf 16 mothers who were having vaccine failure infants, 15 (93.8%) were HBeAg positive and infected with genotype C (15/15, 100%). Among 88 mothers of having children being protected by vaccine, 51 (58.0%) were HBeAg positive, with 45.1% (23/51) of genotype C. The proportion of genotype C in HBeAg mothers of infants with vaccine failure, was significantly higher than that of mothers with vaccine protected infants (chi2 = 14.3, P = 0.003). However, the frequencies of T1762/A1764 mutations had no significant differences between genotype C HBeAg positive mothers with vaccine failure or protected infants (33.3% and 13.3%, respectively, P = 0.4). No A1896 mutation was found in these two groups.

CONCLUSIONHBV genotype C might contribute to the immune failure of HBV vaccination in mother-to-infant transmission, while PreC/BCP mutation might not have correlation with it.

OBJECTIVETo study the changes of platelet in May-Hegglin anomaly (MHA) and the molecular pathogenesis mechanism.

METHODSPeripheral blood was drawn from the MHA proband, her father and her uncle. Platelet count and morphology were examined by automatic blood cell counter and microscopy, respectively. The platelet membrane protein was examined by flow cytometry. Membrane antibodies were determined by ELISA. PCR was used to amplify the exons 25, 31 approximately 32, 38 and 40 of the MYH 9 gene in the MHA patient and her diseased father. Furthermore, PCR products were sequenced, a specific point mutation was identified and inclusions (Dohle's body) in the neutrophil was detected by indirect immunofluorescence technique.

RESULTSIt was proved that in MHA patients, platelet count was higher by cell counter than by microscope (P < 0.01). Giant platelet was 94% but platelet membrane proteins (CD41, CD61, CD42A, CD42b) were in normal range. Membrane antibodies was undetectable. An A5521G mutation (GAG-->AAG) in the exon 38 was found in the proband and her diseased father, resulting in a characteristic change of NMMHC-A1841 (Glutamic acid-->Arginine), which was not found in other members of the family and in normal controls. Spindle-like inclusions with fluorescence were clearly displayed in neutrophil cytoplasm.

CONCLUSIONThe molecular pathogenesis mechanism of May-Hegglin anomaly is the mutation in MYH 9 gene.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.

Objective To explore the in vitro and in vivo antimicrobial activity of antipsychotic agent pimozide against Staphylococcus aureus(S.aureu).Methods The minimal inhibitory concentration(MIC)and minimum bactericidal concentration(MBC)of pimozide were determined by micro-dilution assay.Biofilm was cultured in 96-well cell culture plate,and the anti-biofilm activity of pimozide was detected by turbidimetry.The effect of pimozide on biofilm was further observed through laser confocal microscopy and SYTO9/PI staining.Combined antimicrobial effect of pimozide and other antimicrobial agents was detected by chessboard dilution method,and cytotoxicity of pimozide was detected by CCK-8 assay kit.A model of skin abscess was constructed,in vivo antimicrobial activity and toxicity of pimozide was tested.Results Pimozide showed significant dose-dependent antimicrobial activity against S.aureu,with a MIC of 8-16 μg/mL.It could significantly inhibit the formation of S.aureu biofilm and disperse the formed biofilm.The combination of pimozide and doxycycline has a synergistic antimicrobial effect in vitro,with a synergistic antimicrobial index of 0.5.It can significantly reduce the bacterial load in mouse abscess tissue in vivo,and reduce the live bacterial count from(8.25±0.13)lgarithmic value of CFU/abscess to(3.31± 0.81)logarithmic value of CFU/abscess(q=3.74,P＜0.05).The cytotoxicity of pimozide was extremely low,with a half inhibitory concentration of 64 μg/mL on cells.Conclusion Pimozide exhibits significant antimicrobial activity in vitro and in vivo with extremely low toxicity,thus is promising for the treatment of S.aureu-related local infection in psychiatric patients.

OBJECTIVETo assess the effect of long-term high-fat diet on the expressions of insulin receptor substrates in the hippocampus and spatial learning and memory ability of obese rats.

METHODSA total of 100 4-week-old male SD rats were randomly divided into two groups and fed with common diet (CD group, n=40) or high-fat diet (HFD group, n=60) for 16 weeks. At 4, 8, 12, 16 and 20 weeks, 8 rats were randomly selected from each group for testing their spatial learning and memory function using Morris water maze. After the tests, the rats were sacrificed for measurement of the metabolic parameters and detection of the expressions of insulin receptor substrate-1 (IRS-1) and IRS-2 mRNAs in the CA1 region of the hippocampus.

RESULTSCompared with those in CD group, the rats in HFD group showed a prolonged escape latency, longer swimming distance, faster average swimming speed, and shorter stay in the platformat 12 weeks. In HFD group, the serum levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and fasting insulin were all significantly increased (P<0.05) and the level of high-density lipoprotein cholesterol decreased (P<0.01) in comparison with those in CD group at each of the time points. No significant difference was found in fast glucose levels between the two groups (P>0.05), but the expressions of IRS-1 and IRS-2 mRNAs were significantly decreased in HFD group at 12 weeks (P<0.05).

CONCLUSIONIn obese rats, long-term feeding with high-fat diet leads to insulin resistance, which interferes with hippocampal expression of insulin receptor substrates and insulin metabolism to cause impairment of the cognitive function and accelerate cognitive deterioration.

OBJECTIVE: To investigate the role of tacrolimus-binding protein 38 (FKBP38) in follicle development and the mechanism by which Fkbp38 gene deletion causes premature ovarian insufficiency (POI). METHODS: The Cre-loxp system was used to construct oocyte-specific Fkbp38 knockout transgenic mice. The genotype of the transgenic mice was identified using PCR, and the expression of FKBP38 in the oocytes was verified. The numbers of primordial follicles, primary follicles, secondary follicles and antral follicles in Fkbp38 knockout mice and non-transgenic littermate control mice were counted with HE staining under a microscope for analyzing the effect of Fkbp38 deletion on follicular development. The fertility and serum sex hormone levels of the mice were determined by reproduction experiments and ELISA to assess ovarian function. Ovarian granulosa cell apoptosis of the mice was assessed using TUNEL assay. The activity of the downstream target protein of phosphorylated ribosomal S6 (PS6) of mTOR signaling pathway was detected, and the expressions of BCL-2 and BAX proteins were determined using immunofluorescence assay for assessing oocyte development in the mice. RESULTS: The oocyte-specific Fkbp38 knockout transgenic mouse model was successfully constructed, which showed decreased fertility, disordered sex hormone levels, and significantly reduced primordial follicles, primary follicles and secondary follicles in the ovary (P < 0.05), demonstrating POI-like changes. Compared with the control mice, oocyte-specific Fkbp38 knockout caused activation of the mTOR signaling pathway, significantly increased apoptosis of the granulosa cells, and obviously increased the BAX/BCL- 2 ratio by increasing BAX expression and reducing BCL-2 expression in the oocytes (P < 0.05). CONCLUSION FKBP38 plays an important role in follicle development, and Fkbp38 gene deletion in mice causes POI possibly by activating the mTOR signaling pathway and inducing granulosa cell apoptosis.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
