OBJECTIVE To systematically investigate the current status and effectiveness of the standardized on-the-job training program for community clinical pharmacists in Shanghai， and to provide a scientific basis for optimizing the training scheme. METHODS A questionnaire survey was conducted to collect the data from trainees and mentor pharmacists who participated in the program between 2016 and 2024. The survey examined their basic information， evaluations of the training scheme， satisfaction with training outcomes， and suggestions for improvement. Statistical analyses were also conducted. RESULTS A total of 420 valid responses were collected， including 340 from trainees and 80 from mentor pharmacists. Before training， only 30.29% of trainees were engaged in clinical pharmacy-related work， whereas this proportion increased to 73.24% after training. Most mentor pharmacists had extensive experience in clinical pharmacy （76.25% with ≥5 years of experience） and mentoring （78.75% with ≥3 teaching sessions）. Totally 65.59% of trainees and 55.00% of mentor pharmacists believed that blended training yielded the best learning outcomes. Over 80.00% of both trainees and mentor pharmacists considered the overall training duration， theoretical study time， and practical training time to be reasonable. More than 95.00% of trainees and mentor pharmacists agreed that the homework and assessment schemes were appropriate. Trainees rated the relevance of training content to their actual work highly （with an average relevance score ＞4.5）， though they perceived the chronic disease medication therapy management module as significantly more challenging than the prescription review and evaluation module and the home-based pharmaceutical care module. The average satisfaction score of trainees and mentor pharmacists with the training effectiveness of each project was above 4 points， indicating a high overall satisfaction. Inadequate provision of teaching resources was unanimously recognized by trainees and mentor pharmacists as the key area requiring improvement. CONCLUSIONS The standardized on-the-job training program for community clinical pharmacists in Shanghai has contributed to improving pharmaceutical services in community healthcare settings. However， ongoing improvements must concentrate on content design， resource development， and faculty cultivation.

Objective To investigate the clinical manifestations,molecular genetics and gonadal pathol-ogy characteristics of patients with disorders of sex development(DSD),and to summarize the clinical experi-ence of identifying rare diseases from common symptoms.Methods The clinical data of 416 patients with DSD diagnosed and treated in the multidisciplinary center of DSD of Guangzhou Women and Children's Medical Cen-ter from May 2018 to August 2023 were retrospectively analyzed,summarized and discussed.Results Accord-ing to chromosome karyotype,416 cases of DSD were classified into three types:92 cases(22.1％)of abnormal sex chromosome karyotype,285 cases(68.5％)of 46,XY karyotype and 39 cases(9.4％)of 46,XX karyotype.Among the 92 patients with abnormal sex chromosome karyotype,59 cases were raised as males,18 cases(30.5％)complained of short penis with hypospadias and cryptorchidism.The most common karyotype was 45,X/46,XY(58 cases,63.0％).Among the 285 patients with 46,XY karyotype,238 cases were raised as males,and 63 cases(26.5％)complained of short penis and hypospadias;47 cases were raised as females,and 13 ca-ses(27.7％)complained of inguinal mass.A total of 216 patients with 46,XY karyotype were subjected to whole exome gene detection,and 155 cases(71.8％)were found to have molecular pathogenesis with the clinical phe-notype.Among the 39 patients with 46,XX karyotype,19 cases were raised as males,and 8 cases(42.1％)com-plained of short penis and hypospadias.In the 18 cases of gonad biopsy,17 cases showed testicular tissue in go-nads.Whole exome sequencing was performed in 14 cases.NR5A1 gene heterozygous mutation,SRY gene muta-tion and SOX3 gene mutation were found in 2 cases,respectively(14.3％).Twenty cases were raised as females,and 14 cases(70.0％)complained of clitoral hypertrophy.Gonad biopsy was performed in 8 cases,with 7 cases of ovotestis(87.5％)and 1 case of NR5A1 gene heterozygous mutation(14.3％).Conclusions The etiologies of DSD are complex and diverse,and the clinical manifestations are various,which can be manifested as hypospa-dias,micropenis,cryptorchidism and other common symptoms of the urinary system.Different etiologies have dif-ferent treatment options.Therefore,chromosome karyotype,molecular genetic testing and gonadal pathology can be used to clarify the cause of disease,especially for rare diseases,improve the detection rate,reduce the rate of missed diagnosis,and ensure reasonable treatment,especially sex selection.

OBJECTIVE：To investigate the effects and mechanism of puerarin （Pue） on hypoxia-induced pyroptosis of pulmonary artery smooth muscle cells （PASMCs）. METHODS ：PASMCs of rats as research objects were randomly divided into normoxia group ，hypoxia group and hypoxia+Pue group （0.2 mmol/L）. Except for normoxia group ，other groups were cultured with 5％ CO2 and 3％ O2 at 37 ℃ for 24 hours to establish hypoxia model. Western blot assay was used to detect the expression of pyroptosis related proteins [NOD-like receptor protein- 3 （NLPR3），caspase-1，interleukin-1 β （IL-1 β），apoptosis-associated speck-like protein （ASC）]. Lactate dehydrogenase （LDH）release assay was used to detect the release of LDH in cells ；Hoechst 33342/PI double staining test was adopted to detect the proportion of pyroptosis positive cells. PASMCs was randomly divided into normoxia group+control plasmid group ，hypoxia+control plasmid group ，hypoxia+over-expression plasmid group and hypoxia+ over-expression plasmid+Pue group. Except for the normoxia+control plasmid group ，the other groups were established hypoxia model by the same method. After transfection of control plasmid or NLRP 3 over-expression plasmid ，Western blot ，LDH release test and Hoechst 33342/PI double staining test were used to investigate whether Pue could inhibit hypoxia-induced PASMCs pyroptosis by interfering with the activity of NLRP 3 inflammasomes. RESULTS ：Compared with normoxia group ，the expression of pyroptosis related proteins ，the release of LDH and the proportion of pyroptosis positive cells were increased significantly in hypoxia group （P＜0.05 or P＜0.01）. Pue had the effect of reversing the above indexes （P＜0.05 or P＜0.01）. When the NLRP 3 inflammasome was over-expressed ，the expression of pyroptosis related proteins ，the release of LDH and the proportion of Δ 基金项目：黑龙江省自然科学基金资助项目（No.ZD201416） pyroptosis positive cells were increased significantly （P＜0.05 ＊教授，博士生导师 ，博士。研究方向 ：心血管药理学 。电话： or P＜0.01）.

We studied the construction of fusion protein TAT-RIG-I-GFP prokaryotic expression vector and verified the function of TAT in transmembrane delivery. First, four pairs of specific primers were designed, and the RIG-I gene of Mallard Duck (Anas platyrhynchos) was cloned. Then, the pET-TAT-RIG-I-GFP and pET-RIG-I-GFP prokaryotic expression vectors were constructed. Meanwhile, they were converted to E. coli BL21 (DE3), which were induced to be expressed after culture. After the purification of His-60 nickel affinity chromatography column and the identification of SDS-PAGE, the purified TAT-RIG-I-GFP and RIG-I-GFP proteins were incubated to DF-1 cells. Finally, fluorescence microscopy was used to observe whether the corresponding fluorescence was produced in DF-1 cells. The results showed that pET-TAT-RIG-I-GFP fusion with TAT showed obvious green fluorescence in DF-1 cells. However, the pET-RIG-I-GFP without TAT cannot display green fluorescence. This shows that TAT-fused protein have successfully delivered DF-1 cells and play a key role in transmembrane delivery. In conclusion, these results provide a solid material basis for further study of antiviral drugs in poultry.

Objective To explore the characterization of thyroid stimulating hormone receptor(TSHR) gene mutational spectrum in children with hyperthyroidism from Guangzhou. Methods Ninety children were diagnosed with hyperthyroidism from July 2009 to July 2014 in our institute. Their median age at diagnosis was(7.5± 3.4) years, and there were 28 males and 62 females. Mutational analysis were performed by performing polymerase chain reaction (PCR) and DNA direct sequencing of exon 10 of TSHR gene. TSHR gene mutations from 50 unrelated healthy children were served as controls. The correlation between TSHR gene and hyperthyroidism in children was explored. Results A total of 3 mutations were identified in ninety children who were diagnosed with hyperthyroidism, one synonymous mutations(p.V614V), and two missense mutations( p. R707W and p. D727E). Mutation of p. V614V do not change amino acid and do not influence the structure and function of TSHR, no pathogenicity. p.R707W is a SNP associated with human cancers. The frequency of C allele of the D727E in children with hyperthyroidism was 86.7%, while 55.0% in the controls, significant different between the children with hyperthyroidism and the controls( P＜0. 01). In this study, a very high association between the D727E SNP and hyperthyroidism ( OR=18. 86, P＜0. 01) was found. Conclusion Three different mutations of TSHR gene exon 10 were identified in 90 children with hyperthyroidism, (c.1842A＞G,p.V614V、c.2119C＞T,p.R707W、c.2181G＞C,p.D727E), there were association between p.D727E and hyperthyroidism, nor p. V614V and p. R707W. Finally, p. D727E may be correlated with hyperthyroidism in children.

Objective:To investigate the effects of an atypical antipsychotic drug olanzapine on the body mass index(BMI), leptin and hypothalamic neurohormone related to appetite regulation in the first-attack psychotic patients after 4-week treatment. Methods:Totally 38 first-attack psychotic patients meeting DSM-Ⅳ diagnostic criteria were treated with olanzapine for 4 weeks. The BMI,blood lipids,blood glucose and neurohormone were measured before and after the treatment. The normal control group was also considered the above indices. Results:After the 4-week treatment, the body weight and the body mass index increased significantly when compared with those before the treatment (P < 0.01),and the plasma levels of TC,TG and LDL were higher than those before the treatment(P < 0.05). Both leptin and NPY levels significantly increased in the patients after the treatment (P <0.05),while the NPY levels were significantly lower before the treatment when compared with those in the control group(P< 0.05). The α-MSH levels before and after the treatment were significantly lower than those in the control group(P < 0.01). The CART levels had no significant difference among the pre-treatment group, post-treatment group and control group (P >0.05). Conclusion:The levels of leptin and neurohormone may be changed in the early treatment of olanzapine in the patients with schizophrenia,which may cause weight gain.

Cloning of large genomic sequences is an enabling technology in synthetic biology. To obtain large gene fragments, traditional cloning methods are faced with various defects, for instance, random library cloning relies always on high-throughput screening. It is difficult to get gene fragments more than 10 kb by PCR amplification. Assembly of small fragments is labor intensive with high mutation rates. It is difficult to find suitable cleavage sites on the fragment ends by restriction endonuclease. Recently genome-wide editing creates a new high-performance large fragments cloning methods. For example, CRISPR/cas9 system can identify and cut 20 bp nucleic acid sequences recognition sites used to obtain any desired gene fragments; if combined with Gibson or transformation associated recombination (TAR) assembly technology, these methods can efficiently clone large fragments. This article introduces large fragments cloning technology by classification, then proposes the choice criteria of methods for cloning gene fragments of different sizes.

Objective To explore a new index for reflecting the topological information of brain functional networks in patients at high risk of Alzheimer disease using characteristics of resting-state functional connectivity strengths(FCS) in patients with amnestic mild cognitive impairment(aMCI). Methods Thirty-one aMCI patients and 42 age, gender and years of education matched normal controls were enrolled between September 2009 and April 2011 in this study. The resting-state functional MRI (rs-fMRI) data of all participants were acquired and preprocessed. Then the whole-brain functional connectivities were constructed for exploring the distribution characteristics of hub regions which had higher FCS values. Using two-sample t test to compare group differences in age, years of education and each neuropsychological assessment. In addition, using Chi-squared test to compare group differences in gender. Group differences in FCS values were analyzed by general linear model. Finally, correlation analyses were used to evaluate the relationships between the FCS values of the brain regions with group differences and behavioral scores in aMCI patients. Results The hub regions of the functional networks in the aMCI patients were mainly located in the association cortices such as the precuneuses, posterior cingulate cortices, medial prefrontal cortices, angular gyri, superior occipital gyri, fusiform gyri and lingual gyri. The distribution models in the aMCI patients were consistent with those in the normal controls. However, the FCS values of these brain regions were significantly lower in the aMCI patients than those in the normal controls. In comparison to the normal controls, the aMCI patients had significantly decreased FCS values in the bilateral fusiform gyri, lingual gyri, superior occipital gyri, left middle occipital gyrus and postcentral gyrus (the cluster was 389, 230, 187 and 107 voxels, respectively;P<0.05, respectively), and they had decreased trends of FCS values in the bilateral posterior cingulate cortices and right insulas. The correlation analysis with uncorrected conditions showed that the FCS values of the left postcentral gyri were correlatid with the clock drawing test (CDT) scores (r=0.436, P=0.026). Conclusions aMCI mainly attacks the hub regions of brain functional networks. The changes of functional connectivities in aMCI may reflect the early pathophysiologic alterations of AD.
