[Summary] The clinical data of 3 inpatients clinically diagnosed as Gitelman syndrome ( GS ) were collected. The genomic DNA was isolated from the peripheral blood and the primers were designed to amplify all the exons and flanking introns in the SLC12A3 and CLCNKB genes by PCR. Direct sequencing of PCR products in the two genes was performed in all patients. Three patients manifested with recurrent hypokalemia, hypomagnesemia, hypocalciuria, hypochloremic metabolic alkalosis, but normal blood pressure. Gene sequencing results showed that one novel mutation p. L891V was identified in SLC12A3 gene in case 2. Seven and 12 types of polymorphic loci in the CLCNKB gene were found in case 1 and case 3, respectively. However, mutations were not found in the SLC12A3 and CLCNKB gene.

Objective21 -hydroxylase deficiency ( 21-OHD) patients are at high risk of developing metabolic syndrome.Low dose of glucocorticoid is crucial in the treatment.This study is to investigate the effect of glucocorticoid therapy on potential metabolic disorders.Methods Thirty-two treated and 31 untreated 21-OHD patients were recruited.The components of metabolic syndrome were investigated in both groups.Results Serum testosterone [ (0.61 ±0.12 vs 4.10±0.66) ng/ml,P＜0.01 ],17-(OH) progesterone[ 17-OHP,( 14.83±3.48 vs 48.52±4.72 )ng/ml,P＜0.01 ],dehydroepiandrosterone sulfate[ DHEAS,(55.7±23.6 vs 405.2±65.7 ) μg/dl,P＜0.01 ],and ACTH[ ( 105.8±44.7 vs 617.4± 163.3 ) pg/ml,P＜0.01 ] levels were significantly reduced,whereas body mass index [ ( 23.2±0.9 vs 21.1 ±0.5 ) kg/mz,P＜0.05 ],systolic blood pressure [ ( 120.5 ± 1.3 vs 115.5 ± 1.8 ) mm Hg,P＜0.05,1 mm Hg =0.133 kPa ],serum triglyceride [ ( 1.8±0.2 vs 1.1 ±0.1 ) mmol/L,P＜0.05 ],and homeostasis model assessment for insulin resistance [ HOMA-IR,( 2.07 ± 0.27 vs 1.16 ± 0.12 ),P ＜ 0.01 ] were markedly increased in glucocorticoid treated group.Multivariates regression analysis showed that body mass index was the most important risk factor for HOMA-IR.The correlation of glucocorticoid replacement and HOMA-IR was not observed after adjustment of age and body mass index.ConclusionGlucocorticoid treatment increases body weights,which leads to insulin resistance and metabolic disorders for 21-OHD patients.More attention should be paid to control BMI and metabolic disturbances in 21-OHD patients.

Objective To explore the efficacy of pulse infusion of gonadorelin (LHRH) on the patients with idiopathic hypogonadotropic hypogonadism (IHH) via a micro infusion pump. Methods The protocol was designed as an open, self-controlled prospective study. 31 patients were enrolled and assigned to 3 groups: 23 males without gonadotropin-releasing hormone ( GnRH ) pulse ( group A), 2 males with GnRH pulse frequency insufficiency ( group B), and 6 females ( group C). All the subjects were admitted LHRH every 90 min via the micro infusion pump for 24 weeks. Sex hormones and related characteristics were compared before and after the treatment. Results After 24-weeks treatment, LH peak value reached ( 6. 92 ±5.66 ), ( 9. 55 ±0. 98 ), and ( 6. 93 ±4. 52 ) IU/L; and FSH peak value reached ( 7.44 ± 3. 80 ), ( 12. 85 ± 12. 80 ), and ( 7.38 ±4. 98 ) IU/L among 3 groups, respectively. The testosterone also reached ( 3.18± 1.81 ) and ( 5.78±4. 65 ) ng/ml in groups A and B ( all P＜0. 01 ). In groups A and B, the testis volumes were increased, seminal fluid production was found in 7 patients and spermatogenesis in 6 patients. In group C, uterus was enlarged 85.4%, as well as the ovaries of both sides. Menarche was reported in 5 patients. 19. 4% of the studied patients complained uncomfortable at the injection sites, all the symptoms were mild. Conclusion Pulse infusion of LHRH in IHH patients via a micro infusion pump is effective, while the medication system needs improving.

Objective:To evaluate the effect of Salvianolic acid B (Sal B) on the inflammatory responses of vascular smooth muscle cells (VSMCs) in septic mice and the role of circACTA2.Methods:In vivo experiment Eighty-one healthy male C57BL/6 mice, aged 6-8 weeks, were divided into 3 groups ( n=27 each) by a random number table method: sham operation group, sepsis group and Sal B group. Sepsis model was developed by cecal ligation and puncture. After sucessful preparation of the model, Sal B 7 mg/kg/d was intraperitoneally injected once a day for 2 consecutive days in Sal B group. Twenty mice in each group were randomly selected to measure systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and whole blood lactic acid (Lac) and to record the survival within 7 days after developing the model. Seven mice in each group were randomly selected at 48 h after developing the model, and the arterial vascular tissues were collected for determination of the expression of interleukin-1beta (IL-1β) (by immunofluorescence staining), expression of IL-1β, tumor necrosis factor-alpha (TNF-α) and IL-6 protein and mRNA (by Western blot and quantitative real-time polymerase chain reaction, respectively), and expression of circACTA2 (by quantitative real-time polymerase chain reaction). Cell experiment Mouse VSMCs were cultured and divided into 6 groups ( n=3 each) by a random number table method: control group (C group), lipopolysaccharide (LPS) group, Sal B group, si-circACTA2+ C group, si-circACTA2+ LPS group, and si-circACTA2+ Sal B group. The cells were incubated for 24 h with LPS (final concentration 1 μg/ml) in LPS group and with LPS (final concentration 1 μg/ml) and Sal B (final concentration 5 μmol/L) in Sal B group. VSMCs were transfected with si-circACTA2 only in si-circACTA2+ C group. At 24 h after transfection of si-circACTA2 into VSMCs, the cells were incubated with LPS (final concentration 1 μg/ml) in si-circACTA2+ LPS group and with LPS (final concentration 1 μg/ml) and Sal B (final concentration 5 μmol/L) for 24 h in si-circACTA2+ Sal B group. The expression of IL-1β, TNF-α and IL-6 protein and mRNA was detected using Western blot and quantitative real-time polymerase chain reaction, and the expression of circACTA2 was determined by the quantitative real-time polymerase chain reaction. Results:In vivo experiment Compared with sham operation group, SBP, DBP and MAP were significantly decreased, the concentrations of whole blood Lac were increased, 7-day survival rate was decreased, the expression of IL-1β, TNF-α and IL-6 protein and mRNA in arterial vascular tissues was up-regulated, circACTA2 expression was down-regulated ( P<0.05), and the fluorescence of IL-1β was enhanced in sepsis group. Compared with sepsis group, SBP, DBP and MAP were significantly increased, whole blood Lac concentrations were decreased, 7-day survival rate was increased, the expression of IL-1β, TNF-α and IL-6 protein and mRNA in arterial vascular tissues was down-regulated, the expression of circACTA2 was up-regulated ( P<0.05), and the fluorescence of IL-1β was weakened in Sal B group. Cell experiment Compared with group C, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly up-regulated, and the expression of circACTA2 was down-regulated in LPS group ( P<0.05). Compared with LPS group, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly down-regulated, and the expression of circACTA2 was up-regulated in Sal B group ( P<0.05). Compared with si-circACTA2+ C group, the expression of IL-1β, TNF-α and IL-6 protein and mRNA was significantly up-regulated in si-circACTA2+ LPS group ( P<0.05). There were no significant differences in the expression of IL-1β, TNF-α and IL-6 protein and mRNA between si-circACTA2+ LPS group and si-circACTA2+ Sal B group ( P>0.05). Conclusions:Sal B can reduce the inflammatory responses of VSMCs, and the mechanism may be related to promoting the expression of circACTA2 in septic mice.

PURPOSE: The role of IL28B gene variants and expression in hepatitis B virus (HBV) infections are not well understood. Here, we evaluated whether IL28B gene expression and rs12979860 variations are associated with HBV outcomes. MATERIALS AND METHODS: IL28B genetic variations (rs12979860) were genotyped by pyrosequencing of DNA samples from 137 individuals with chronic HBV infection [50 inactive carriers (IC), 34 chronic hepatitis B (CHB), 27 cirrhosis, 26 hepatocellular carcinoma (HCC)], and 19 healthy controls. IL28A/B mRNA expression in peripheral blood mononuclear cells was determined by qRT-PCR, and serum IL28B protein was measured by ELISA. RESULTS: Patients with IL28B C/C genotype had greater IL28A/B mRNA expression and higher IL28B protein levels than C/T patients. Within the various disease stages, compared to IC and healthy controls, IL28B expression was reduced in the CHB, cirrhosis, and HCC cohorts (CHB vs. IC, p=0.02; cirrhosis vs. IC, p=0.01; HCC vs. IC, p=0.001; CHB vs. controls, p<0.01; cirrhosis vs. controls, p<0.01; HCC vs. controls, p<0.01). When stratified with respect to serum HBV markers in the IC and CHB cohorts, IL28B mRNA and protein levels were higher in HBeAg-positive than negative individuals (p=0.01). Logistic regression analysis revealed that factors associated with high IL28B protein levels were C/C versus C/T genotype [p=0.016, odds ratio (OR)=0.25, 95% confidence interval (CI)=0.08-0.78], high alanine aminotransferase values (p<0.001, OR=8.02, 95% CI=2.64-24.4), and the IC stage of HBV infection (p<0.001). CONCLUSION: Our data suggest that IL28B genetic variations may play an important role in long-term development of disease in chronic HBV infections.

OBJECTIVE To provide reference for strengthening the quality of pharmaceutical care in retail chain pharmacies and the professional capabilities of licensed pharmacists， and to meet the public’s pharmaceutical care needs. METHODS A combination of questionnaire survey and informant interview was used to investigate the general information of licensed pharmacists in retail chain pharmacies in Guangdong province， the implementation of pharmaceutical care， the competence and knowledge status of the surveyed licensed pharmacists， and the factors affecting the development of pharmaceutical care. RESULTS & CONCLUSIONS A total of 444 questionnaires were sent out and 326 effective questionnaires were collected， with an effective recovery rate of 73.42%. Among 326 surveyed licensed pharmacists， a college degree or higher accounted for 40.18%， and the pharmacy major or related accounted for 79.75%. A total of 185 （56.75%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked had established specified areas of pharmaceutical care； 320 （98.16%）， 137 （42.02%） and 181 （55.52%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked could provide services such as rational medication guidance for patients， decocting traditional Chinese medicines and establishing health records， etc. The self-assessment scores of the surveyed licensed pharmacists were significantly higher than 3 （median） for competence and knowledge level， but the self-assessment scores for medication therapy management competence and pharmaceutical care practice were relatively low. The surveyed licensed pharmacists believed that the main factors affecting the development of pharmaceutical care in retail chain pharmacies included patients’ lack of trust or cooperation （196， 60.12%）， sales performance requirements （170， 52.15%）， and heavy daily workload （165， 50.61%）. It is recommended that relevant authorities expedite the legislative process of the Pharmacist Law， optimize the continuing education system for licensed pharmacists， and implement a star-rating evaluation system for pharmaceutical care capabilities in pharmacies， so as to encourage retail chain pharmacies and licensed pharmacists to pursue a more specialized development path. At the same time， pharmaceutical retail chain enterprises should shift their business mindset， increase investment in pharmaceutical care， enhance the professional atmosphere in the pharmacies， optimize the compensation structure for licensed pharmacists， and elevate the pharmaceutical care capabilities of both the pharmacies and licensed pharmacists to fulfill the pharmaceutical care needs of the public.
