AIM: To obtain GST fusion protein of hSP17 gene and construct the recombinant plasmid for expression in E. coli. METHODS: Total fragment of hSP17 cDNA gene were amplified by RT-PCR, then subcoloned into pGEX-3b to generate recombinant hSP17/pGEX. Right orientation of insert are identified by restricted enzyme digestion. Transform the correct recombinant plasmid into the E. coli DH5a. The expression of fusion proteins hSP17-GST were induced by adding isopropylthiogalactoside (IPTG). RESULTS and CONCLUSION: The recombinant plasmid hSP17/pGEX-3b could express effectively in E.coli and a high level of fusion protein hsp17-GST with the predicted molecular weight was detected.

Objective To obtain a more accurate assessment of prognostic significance of NLR in ovarian cancer. Methods A systematic literature search was conducted using the electronic databases PubMed ,Web of Science,and Embase up to May 2016. Hazard ratio(HR)and odds ratio(OR)with 95% confidence interval (95%CI)were calculated. Statistical analysis was performed using Stata 12.0. Results 12 studies,consisting of 3 ,854 patients ,were selected in this meta-analysis. High NLR level was significantly associated with poorer overall survival(OS)(HR:1.69)and shorter progression free survival(PFS)(HR 1.63). Additionally,increased NLR was significantly correlated with advanced FIGO stage(OR 2.32),higher level of CA-125(OR 3.33),more extensive ascites(OR 3.54)as well as less chemotheraputic response(OR 0.53). Conclusions Elevated pretreat-ment NLR can serve as a predicative factor of poor prognosis for ovarian cancer.

Objective: To investigate the characteristics of neuropsychological factors in patients with persistent postural-perceptual dizziness(PPPD) and provide the basis for the psychosomatic comprehensive treatment. Methods: Cartel Personality Test (16PF), Symptom Checklist 90 (SCL-90), HAMA, HDMD, SAS and SDS were used to evaluate personality and mental state in patients with PPPD(PPPD group, n=65) and control group(n=63). Dizziness handicap inventory(DHI) was used to evaluate the degree of vertigo.The correlation analysis was carried out between the DHI scores and 16-PF, SCL-90 factor scores. Results: (1)16PF factor scores: the factor scores of assertiveness(8.50±1.84), excitability (6.59±1.73), boldness (7.46±1.78), sensitivity (7.25±1.79), doubtfulness (6.55±1.74), fantasy(6.20±1.60), anxiety(7.67±1.61) and tension(6.81±1.67)in PPPD group were higher than those in the control group, and the differences were statistically significant (all P<0.05). The gregariousness (4.38±1.65), intelligence (4.51±1.67), stability (3.51±1.75), independence (4.39±1.56) and self-discipline (4.70±1.82) factor scores in PPPD group were lower than those in the control group, and the differences were statistically significant (all P<0.05). (2)SCL-90 factor scores: the factor scores of somatization(1.62±0.40), anxiety (1.64±0.56), interpersonal sensitivity (1.79±0.42), terrifying(1.71±0.53), total points(150.77±21.60), total average score (1.62±0.51) in PPPD group were higher than those in control group (all P<0.05). There were no differences in obsessive-compulsive (1.50±0.55), depression (1.45±0.44), hostility (1.69±0.60), paranoia (1.76±0.53), somatization (1.42±0.49) and psychotic (1.29±0.35) between PPPD group and the control group (all P>0.05). (3)The factor scores of HAMA(9.08±1.77) and SAS(37.88±2.96)in patients with PPPD were higher than that in the control group, and the differences were statistically significant (all P<0.05). There was no significant difference in HAMD (6.19±2.82) and SDS (36.36±4.71) scores between PPPD group and control group (all P>0.05). (4)The DHI scores were positively correlated with assertiveness, sensitivity, tension and doubtfulness factors of 16PF.The DHI scores were positively correlated with somatization, interpersonal sensitivity, anxiety and terrifying factors of SCL-90. Conclusion Patients with persistent postural-perceptual dizziness suffer from personality changes, mental disorders and anxiety disorder.

Objective To summarize and analyze the clinical features and diagnosis and treatment methods of patients with restless leg syndrome (RLS) mainly characterized by abdominal symptoms, and provide the basis for improving the correct diagnosis and treatment rate of RLS. MethodsThree patients, admitted to and completed routine laboratory examination (blood analysis, blood biochemistry, serum iron, serum ferritin, etc.), imaging, electroencephalogram, and electromyography in our hospital from August 2018 to April 2019, were chosen in our study. Polysomnography monitor was used to record the patient's sleep process for 12 h. Sleep and psychological status were evaluated by Pittsburgh Sleep Quality Index (PSQI), RLS Self-rating Depression Scale (IRLS), Epworth Sleeping Scale (ESS), RLS-quality of life (RLS-QoL), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD).Results General examination, physical examination of nervous system, imaging, electroencephalogram, electromyography and routine biochemical examination showed no obvious abnormalities in the three patients. Serum iron decreased in two patients. Polysomnography results indicated that the sleep efficiency of the three patients was obviously decreased, the sleep latency was prolonged, the time of awakening during sleep and the times of awakenings were increased; and the sleep structure was disordered; rapid eye movement sleep was significantly reduced. Meanwhile, all three patients had moderate and severe PLM events. Excessive sleepiness in the daytime was noted; the quality of life was affected about one month, and the severity was severe; all three patients had severe anxiety without evident depression. The condition of three patients with pramipexole hydrochloric acid after treatment were significantly improved.Conclusion s RLS subtype with abdominal symptoms as chief complaint is relatively rare in clinical practice. If patients have abdominal pain and discomfort during sleep at night and can exclude organic diseases of the digestive system, the possibility of RLS should be considered. A good therapeutic effect can be obtained by using dopa receptor agonist such as pramipexole.

OBJECTIVE To mine the adverse drug events （ADE） signals for gilteritinib， and provide a reference for safe drug use in clinic. METHODS ADE reports with gilteritinib as the primary suspected drug were extracted from the FDA Adverse Event Reporting System （FAERS） database from February 1st， 2018 to December 31st， 2023. Reporting odds ratio （ROR） and proportional reporting ratio （PRR） were applied to detect the risk signals from the data in the FAERS database. The classification and statistics of collected signal data were conducted by using the preferred term （PT） and systemic organ class （SOC） in ADE terminology set of the Medical Dictionary for Regulatory Activities （24.1 edition）. RESULTS Totally， 2 755 gilteritinib-related ADE reports were collected from the database， involving 676 ADE signals （95 positive signals）， 313 PTs and 25 SOCs. Among them， nine signals were not recorded in the package insert. The top 5 PTs consisted of abnormal liver function， decreased platelet count， febrile neutropenia， pneumonia and myelosuppression. The top 6 SOCs for positive signal counts were examinations， general disorders and administration site conditions， respiratory， thoracic and mediastinal disorders， infections and infestations， heart organ disorders， and nervous system disorders. ADEs not recorded in the drug package insert included pneumonia， myelosuppression， decreased blood cell count， sepsis， hemorrhage， infection （not specifically referred to）， septic shock， respiratory failure， and aspergillosis. CONCLUSIONS In addition to paying attention to common ADEs such as liver dysfunction and thrombocytopenia， it is necessary to monitor ADEs with strong signals that are not mentioned in the drug instructions when using gefitinib， such as pneumonia， bone marrow suppression， cytopenia， sepsis， bleeding， infection （not specifically referred to）， septic shock， respiratory failure， Aspergillus infection， elevated serum creatinine and interstitial lung disease.

Background Perfluorinated alkyl substances (PFAS) are a class of synthetic organic fluorides, which have adverse health effects on brain function, and limited research has been conducted on their effects on depression. Objective To assess potential correlation between serum PFAS and depression. Methods Using the 2015—2016 and 2017—2018 National Health and Nutrition Examination Survey (NHANES) datasets, 2626 subjects with complete relevant information in people ≥20 years old were selected. Logistic regression and restricted cubic splines were used to analyze the association and dose-response relationship between serum PFAS concentration and depression. Subgroup analysis was performed on sex, age, race, education level, marital status, family income to poverty ratio, moderate exercise, body mass index, and drinking status. Results Among the 2626 subjects, there were 666 patients (25.4%) with mild or above depression. After adjusting for race, education level, marital status, body mass index, moderate exercise, drinking history, cotinine, and other types of PFAS, serum perfluorooctane sulfonate (PFOS) was positively associated with the risk of depression (OR=1.85, 95%CI: 1.14, 3.02), and showed a nonlinear dose-response relationship (χ²=6.37, P_nonlinear=0.012). Perfluorononanoic acid (PFNA) was inversely associated with the risk of depression (OR=0.23, 95%CI: 0.14, 0.39), and showed a linear dose-response relationship (P_trend<0.001, χ²=35.13, P_overall<0.001). After subgroup analysis, it was found that males, 20-39 year-olds and 40-64 year-olds were more sensitive to PFNA exposure (OR=0.15, 95%CI: 0.06, 0.37; OR=0.16, 95%CI: 0.06, 0.40; OR=0.18, 95%CI: 0.08, 0.39). PFOS only showed a statistically significant health effect in people aged 20-39 years (OR=3.00, 95%CI: 1.14, 7.94). In addition, among subgroups of non-Hispanic blacks, cohabitants, current drinkers, high school graduates, and obese patients, exposure to PFAS was significantly associated with the risk of depression. Conclusion PFOS exposure may be associated with increased levels of depression, whereas PFNA exposure may be protective.

OBJECTIVE To investigate the present equipment and management situation of narcotic drugs in primary healthcare institutions from Qiandongnan prefecture of Guizhou province. METHODS The questionnaire survey was conducted among pharmacy department heads and medical staff from primary healthcare institutions in Qiandongnan prefecture of Guizhou province. Descriptive statistical analysis was conducted on the survey results. RESULTS Of 251 healthcare institutions in this survey， 29 healthcare institutions were equipped with narcotic drugs， accounting for 11.55%. The reasons for the narcotic drugs unequipped were mainly as follows: insufficient attention， no storage conditions for narcotic drugs， complex program of narcotic drug management， small amount usage and so on. Among the 29 primary healthcare institutions equipped with narcotic drugs， all of them did not monitor patient usage， accounting for 100%； 29 healthcare institutions did not implement a return visit or follow-up every 3 months， accounting for 100%. CONCLUSIONS The health administration departments should strengthen the administration of narcotic drugs in primary healthcare institutions. At the same time， training on standardized management and clinical rational application of narcotic drugs for medical staff in primary healthcare institutions should be enhanced by the health administrative department.
