Objective To identify the genetic variants of WNK4(with no K=lysine kinase)gene in Kazak population in Xinjiang province,to determine whether the WNK4 gene intron 10 polymorphism iS associated with essential hypertension(EH)and to investigate the distribution of genotype and allele frequencies of WNK4 gene. Methods One hundred and ninety-one patients with EH and 173 normal blood pressure controls were included in the study to assess the contribution of polymorphism of WNK4.Direct DNA sequencing was performed to identify the single nucleotide polymorphism(SNP)in 16 SUbjects with EH and 16 subjects of normotension(NT).Then the polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method was used for the detection of WNK4 genotype. Results One SNP located in the 10 intron of WNK4 (1156666 base of chromosome 17)was found in the Kazak population.The genotypes of the variants were found to be in Hardy-Weinberg equilibrium.GG,AG,AA genotypes were 88.0%,11.0 oA,1.0%in the EH group and 91.9%,8.1%,0%in the NT group,respectively.The frequencies of genotype and allele in EH group were not significantly different from NT group in Kazak population.Conclusions It suggests that the intron 10 polymorphism of WNK4 gene might be not associated with hypertension in Kazak population.

Objective To study the sonographic features of fetal lung in normal and preeclampic pregnancies,with follow-up on the occurrence of neonatal respiratory distress syndrome (NRDS),as well as,examine the effects of preeclampsia (PE) on fetal lung maturity (FLM).Methods We collected data from 140 cases during the early pregnancy period (29 to ＜34 weeks),100 cases during the late pregnancy period (34 to 39 weeks),as well as 240 cases of normal pregnancies with the same gestational ages for the contwl group.Data included the parameters of fetal lung maturity measured by ultrasound and the incidence of NRDS postpartum.We analyzed the effects of PE on fetal lung maturity.Results The right fetal lung from the early onset PE group was significantly smaller than that of the normal group.There was no difference in the right lung area between the PE group and the normal group of the same gestational age.Compared with the normal group of the same gestational age,the LHR group had no difference in the early and late PE groups.The acceleration time/ejection time of the main pulmonary artery in the early and late PE group was significantly higher than that of the normal group.There was no difference in the incidence of NRDS among all the groups of the same gestational age.Conclusion PE has no significant effect on fetal lung function or maturation of the pulmonary tissues.Lung maturation may precede the same gestational age without PE.

BACKGROUND:Calcium channel abnormalities can damage myocardium. Heroin can directly affect calcium ion channel, and alter myocardial structure.
OBJECTIVE:To study the changes of heroin-induced myocardial ultrastructure, L-type calcium channel current and action potential of myocardial cel s after rat cardiac arrhythmia.
METHODS:Sprague-Dawley rats were randomly divided into control group and model group. In the model group, rats were administered heroin at initial dose of 5 mg/kg?d. The daily dose escalation method was used (increasing dose:2.5 mg/kg?d) to replicate rat models of heroin addiction. At 20 days, models of heroin addiction were successful y established. At 30 days after increasing the dose, rat models of heroin addiction-induced arrhythmias were further established.
RESULTS AND CONCLUSION:Compared with the control group, the electron microscopy demonstrated that myocardial structure changes mainly presented nuclear membrane shrinkage, nuclear condensation, nuclei became smal , chromatin assembled into blocks, mitochondria disordered and disappeared, sarcomeres disordered, focal fracture, and unclear myofilament in rat models of heroin addiction. Electric current-voltage curve of myocardial cel L-type calcium channel current showed the increasing trends. The 90%repolarization action potential was significantly shortened. These data indicated that heroin can directly lead to the pathological change of myocardial structure. Calcium channel current change is one of the main reasons for myocardial injury.

Abstract BACKGROUND:Caspase-8 plays an important role in starting the process of cel apoptosis, and diacetylmorphine can induce neuronal apoptosis. The relationship between the apoptosis of cerebelar granule neurons cels induced by diacetylmorphine and caspase-8 has not been reported. OBJECTIVE:To investigate the effect of caspase-8 on diacetylmorphine-induced neuronal apoptosis. METHODS:Cerebelar granule neurons from Sprague-Dawley rats aged 7 days were culturedin vitro. At 7 days, the cels were cultured with different dosage of diacetylmorphine (10, 40, 80, 100, 120 mg/L) and SP600125 for 24 hours, and were divided into control group, 80 mg/L diacetylmorphine group, diacetylmorphine+SP600125 group. Cel morphology was observed by Hoechst 33258 fluorescent staining, and cel apoptosis rate was measured by flow cytometry. Immunofluorescence staining, RT-PCR and western blot assay were used to detect caspase-8 mRNA and protein expression. RESULTS AND CONCLUSION:(1) After different dosage of diacetylmorphine was used to induce neuronal apoptosis, dark blue translucent apoptotic bodies were found in apoptotic cels, appearing with nucleus condensation, cohesion and fracture, and the apoptosis rate presented an increasing trend with increasing of drug dosage (P < 0.05). (2) Compared with the control group, caspase-8 mRNA and protein expression was remarkable under the intervention of 80 mg/L diacetylmorphine(P < 0.05); caspase-8 mRNA expression exhibited an increasing trend with increasing dosage of diacetylmorphine (P < 0.05), while caspase-8 mRNA and protein expression in the diacetylmorphine+SP600125 group was significantly lower than that in the 80 mg/L diacetylmorphine group (P < 0.05). These findings indicate that caspase-8 is involved in the process of diacetylmorphine-induced neuronal apoptosis, and meanwhile, it is also an important candidate of pro-apoptotic factors in the c-jun N-terminal kinase signaling pathway.

Objective:To analyze the clinical manifestations and laboratory features of brucellosis patients in order to provide help for clinical diagnosis.Methods:The medical records of confirmed brucellosis patients ( n=81) in Kunming Third People's Hospital from 2015 to 2019 were collected. The occupation, contact history, clinical manifestations, laboratory examination characteristics and treatment of the patients were retrospectively analyzed. Results:The 81 cases of brucellosis were mainly farmers (64 cases), most of who had a history of raising sheep or contacting sheep manure or secretions (71 cases). The clinical manifestations were fever (68 cases), low back pain (42 cases), joint pain (22 cases), including 72 cases in acute stage and 9 cases in chronic stage. Laboratory examination showed that liver function index total bilirubin (TB) and direct bilirubin (DB) were generally normal, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyltransferase (GGT) were increased in about half of the patients; high sensitivity C-reactive protein (HsCRP), procalcitonin (PCT), interleukin-6 (IL-6) and serum amyloid A (SAA) were increased in more than 80% of the patients, and erythrocyte sedimentation rate (ESR) was increased in 64.6% (42/65) of the patients. Doxycycline plus rifampicin was the first-line treatment program.Conclusion:The clinical manifestations of patients with brucellosis are diverse and atypical, and patients with nonspecific clinical manifestations such as fever should be combined with their occupation, contact history, indicators of infection detection, timely blood culture examination to make a clear diagnosis, and patients with abnormal liver function should pay attention to asking about occupation and contact history, so as to reduce misdiagnosis and mistreatment of brucellosis.

Objective:To compare the efficacy of different volume of ropivacaine for subomohyiod anterior suprascapular nerve block (aSSNB) in the patients undergoing arthroscopic shoulder surgery with general anesthesia.Methods:One hundred and thirty-five patients of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective arthroscopic shoulder surgery, were divided into 3 groups ( n=45 each) using a random number table method: 0.5% ropivacaine 5 ml group (L group), 10 ml group (M group), and 15 ml group (H group). Before induction, aSSNB was performed with 0.5% ropivacaine 5, 10 and 15 ml in L, M and H groups, respectively.Diaphragmatic excursion, occurrence and degree of diaphragmatic paralysis, decrease in SpO 2, dyspnea and Horner syndrome were recorded at 30 min after injection.The intraoperative consumption of remifentanil and cardiovascular events were recorded.The extubation time, length of post-anesthesia care unit stay, and duration of sensory block were recorded.Quality of Recovery-15 scale score and score for patient′s satisfaction with analgesia were recorded.The first pressing time of analgesic pump, effective pressing frequency of analgesic pump, requirement for rescue analgesia, nausea, vomiting and nerve block-related complications within 24 h after surgery were recorded. Results:Compared with group L, the incidence of diaphragmatic paralysis was significantly increased, the degree of diaphragmatic paralysis was aggravated, the first pressing time of analgesic pump and duration of sensory block were prolonged, the effective pressing times of analgesic pump was reduced, and the requirement for rescue analgesia was decreased in M and H groups, and the decrease in SpO 2 was significantly increased, and the introperative consumption of remifentanil was decreased in group H ( P<0.05). Compared with group M, the decrease in SpO 2 and incidence of diaphragmatic paralysis were significantly increased, the degree of diaphragmatic paralysis was aggravated, the first pressing time of analgesic pump and duration of sensory block were prolonged ( P<0.05), and no significant change was found in the introperative consumption of remifentanil, the effective pressing times of analgesic pump or requirement for rescue analgesia in group H ( P>0.05). There was no significant difference in the incidence of cardiovascular events, score for patient′s satisfaction with analgesia, incidence of dyspnea and extubation time, length of post-anesthesia care unit stay, Quality of Recovery-15 sacle score, and the incidence of nausea and vomiting among three groups ( P>0.05). There were no Horner syndrome and nerve block-related complications in the three groups. Conclusions:Subomohyoid aSSNB with 0.5% ropivacaine hydrochloride 10 ml provides optimal efficacy when used for subomohyiod anterior suprascapular nerve block in patients undergoing arthroscopic shoulder surgery with general anesthesia.

This paper aims to provide exploratory ideas for the formulation of relevant systems and strategies of interdisciplinary integration for hospitals.Methods:This paper analyzes the internal influencing factors of interdisciplinary integration and development of hospitals from the perspective of discipline construction participants, and combines the overall requirements of high-quality development of public hospitals with the GREP model to build a strategic analysis framework for interdisciplinary integration of university affiliated hospitals.Results:Hospitals can use this strategic analysis framework to find problems through discipline self-evaluation, interviews, interdisciplinary integration mode and horizontal comparison of typical experiences, and grasp the main problems according to the basic steps of GREP problem solving, propose solutions, and finally draw conclusions.Conclusions:Based on four dimensions, GREP model provides a strategic analysis framework for the implementation path of promoting interdisciplinary integration in hospital design, and has certain practical significance for the formulation of hospital related strategies.

Objective To explore the correlation between hospitalization for severe asthma and climate change among adult residents in Dalian. Methods Clinical data of asthma inpatients in Dalian First Affiliated Hospital from January to December 2022 were collected, and assigned into severe asthma group and non-severe asthma group according to the diagnostic criteria of severe asthma. Spirometer was used for the measurement of (forced expiratory volume in the first second , FEV1) and (forced vital capacity , FVC), and the serum white blood cell count and C-reactive protein level were measured by biochemical analyzer. Meantime, meteorological parameters including monthly average temperature, relative humidity, wind speed and duration of sunshine hours were also collected. Then Spearman correlation analysis was conducted to discuss the correlation between the number of hospitalizations for severe asthma and meteorological parameters. Of the 260 asthma patients, 153 had severe asthma and 107 had non-severe asthma. There were 85 male and 68 female patients with severe asthma. The onset age distribution of severe asthma was concentrated at 60-79 years old, with 94 cases, followed by 50-59 years old (n=26). The peak time of onset in each year was from March to May, with 14, 19 and 16 cases, respectively. The secondary peak was from November to January, with 15, 18 and 13 cases, and there were fewer hospital admissions from June to October. FEV1 and FEV1/FVC values were smaller in severe asthma group than in non-severe asthma group, while the white blood cell count and C-reactive protein levels were higher than those in non severe asthma group (P<0.05). The average monthly temperature in Dalian began to rise in January, reached a peak in August, and then gradually dropped, with the lowest temperature in December. The monthly average humidity reached the peak from July to September. The monthly mean wind speed reached its peak from November to December. The monthly average sunshine reached its peak from June to September. Spearman correlation analysis denoted that the number of hospitalization for severe asthma was not correlated with average sunshine hours and wind speed (P>0.05), but was negatively correlated with average temperature and humidity (P<0.05). Conclusion The number of hospital admissions for severe asthma in Dalian varies with the seasons, therefore, early and active interventions are of great value in preventing severe asthma in months with high variations in temperature and humidity.
