Hypertension and osteoporosis(OP)are common diseases in middle-aged and elderly people,and the number of patients with both diseases has gradually increased in recent years.Because the onset of the disease is hidden,it is easy to cause fractures and serious complications of heart,brain and kidney in the later stage,which not only seriously damages the quality of life of patients,but also increases the difficulty of clinical treatment.Therefore,it is particularly necessary to strengthen the research on this disease.More and more studies have found that the disorder of intestinal flora will lead to the occurrence of OP,while the intestinal flora of patients with hypertension is obviously out of balance.Therefore,this paper thinks that intestinal flora may be the key influencing factor of hypertension complicated with OP,and the imbalance of intestinal flora will lead to the imbalance of short-chain fatty acid metabolism,immune inflammatory reaction and increased sympathetic nerve activity,thus causing the imbalance of bone homeostasis and promoting the occurrence of OP.Therefore,it is suggested that regulating intestinal flora may be a new way to intervene hypertension complicated with OP.

Objective:To understand the symptoms of diarrhea of residents in Tianjin and their willingness to vaccinate, to provide reference for health education, prevention and control of infectious diarrhea.Methods:Cross-sectional study design was adopted. From September to December 2023, a questionnaire survey was conducted among some residents as subjects in Nankai District, Beichen District, Baodi District and Binhai Area of Tianjin by multistage stratified cluster random sampling,to collect information such as sociodemographic characteristics, diarrhea symptoms and vaccination intention. According to the formula n=[ u2απ (1 - π)]/ δ2, the estimated sample size was 3 458 cases. The logistic regression model was used to analyze the factors related to the willingness of the respondents to receive diarrhea vaccination. The software SPSS 24.0 was used for statistical analysis. Results:A total of 3 808 subjects were investigated, with the male-to-female ratio as 1∶1.11 (1 806∶2 002), the age was (42.48±21.59) years old, and the education level of middle school or below accounted for 50.84% (1 936/3 808). The incidence rate of diarrhea was 18.28% (696/3 808), and 48.84% (1 860/3 808) were willing to be vaccinated with diarrhea vaccine. The results of multivariate logistic regression analysis showed that the age was 15-59 years old and ≥60 years old (a OR=2.31, 95% CI:1.80-2.96; a OR=1.66, 95% CI:1.38-2.00), lived in Binhai Area (a OR=2.09, 95% CI:1.62-2.71), and those who knew that community health service centers can provide the vaccination (a OR=1.61,95% CI:1.34-1.92), those who walked from the address to the community health service center were less than 15 minutes (a OR=1.54, 95% CI:1.28-1.85), those who often travel or on business (a OR=1.36, 95% CI:1.07-1.73), and those who actively obtained health care information related to diarrhea prevention when going abroad (a OR=1.69,95% CI:1.43-1.98) were more willing to be vaccinated against diarrhea. Conclusions:The incidence of diarrhea symptoms of residents was slightly higher in Tianjin, but they were less willing to be vaccinated against diarrhea. People who often go outside and go abroad were more willing to be vaccinated against diarrhea. It is suggested that the popular science propaganda and health education of diarrhea vaccine should be effectively carried out by using network platform in community.

Objective:To evaluate knee biomechanics of patients about 12 months after anterior cruciate ligament(ACL)reconstruction during cutting and determine the abnormal biomechanical characteristics.Methods:Sixteen males about 12 months after ACL reconstruction were recruited for this study.Three-dimensional kinematic and kinetic data were collected during cutting movement.Knee joint angles and moments were calculated.Paired t-tests were used to compare the differences in knee biomechanics be-tween the surgical leg and nonsurgical leg.Results:The peak posterior ground reaction force(surgical leg:0.380±0.071;nonsurgical leg:0.427±0.069,P=0.003)and vertical ground reaction force(surgical leg:1.996±0.202,nonsurgical leg:2.110±0.182,P=0.001)were significantly smaller in the surgical leg than in the nonsurgical leg.When compared with the uninjured leg,the surgical leg demonstrated a smaller knee flexion angle(surgical leg:38.3°±7.4°;nonsurgical leg:42.8°±7.9°,P＜0.001)and larger external rotation angle(surgical leg:10.3°±2.4°;nonsurgical leg:7.7°±2.1°,P=0.008).The surgical leg also demonstrated a smaller peak knee extension moment(surgical leg:0.092±0.031;nonsurgical leg:0.133±0.024,P＜0.001)and peak knee external rotation moment(surgical leg:0.005±0.004;nonsurgical leg:0.008±0.004,P=0.015)when com-pared with the nonsurgical leg.Conclusion:The individuals with ACL reconstruction mainly showed asymmetrical movements in the sagittal and horizontal planes.The surgical leg demonstrated a smaller peak knee flexion angle,knee extension moment,and knee external rotation moment,with greater knee external rotation angle.

Objective:To explore the effects of advanced management intervention on clinical efficacy,cardiac func-tion and quality of life in patients with coronary heart disease(CHD).Methods:A total of 105 CHD patients admit-ted in Department of Critical Care Medicine,Shenzhen Longhua District People's Hospital between February 2019 and February 2023 were selected and divided into control group(n=53,routine nursing measure)and intervention group(n=52,advanced management intervention based on pain management)using the random number table method.Both groups were intervened for 1 month.Clinical therapeutic effect,cardiac function indexes,scores of Visual Analogue Scale(VAS),Kolcaba's General Comfort Questionnaire(GCQ),Pittsburgh Sleep Quality Index(PSQI)and World Health Organization Quality of Life brief version(WHOQOL-BREF)before and after inter-vention were compared between two groups.Results:Compared with control group,there were significant rise in therapeutic effective rate(66.00％vs.96.00％),left ventricular ejection fraction[(57.07±1.82)％vs.(68.85±1.81)％],scores of GCQ[(73.12±1.75)points vs.(94.96±1.95)points]and WHOQOL-BREF[(80.10±1.73)points vs.(94.82±1.95)points](P＜0.001 all),and significant reductions in left ventricular end-diastolic diameter[(52.12±1.84)mm vs.(41.28±1.74)mm],left ventricular mass index[(104.81±2.94)g/m2vs.(89.46±2.99)g/m2],left atrial volume index[(37.03±1.16)ml/m2 vs.(27.65±1.09)ml/m2],scores of VAS[(4.94±0.55)points vs.(1.85±0.56)points]and PSQI[(14.11±0.57)points vs.(8.95±0.64)points]in in-tervention group after intervention(P＜0.001 all).Conclusion:Advanced management intervention based on pain management can significantly improve clinical therapeutic effect,cardiac function,relieve pain,improve quality of life,sleep condition and comfort in CHD patients,which is worthy of clinical promotion and application.

Objectives:To investigate whether circumferential pulmonary vein isolation(CPVI)combined with additional ablation reduces the recurrence rate of atrial fibrillation(AF)compared with CPVI alone. Methods:A literature search was conducted using the databases CNKI,Wanfang Data,VIP,Chinese Biomedical Literature Database,PubMed,Embase,the Cochrane Library.Randomized controlled studies that met the standards in recent ten years were screened,and the relevant literature contents were meta-analyzed by Review Manager 5.3 software.The comparison results of CPVI alone with CPVI combined with the additional ablation strategies in the recurrence of AF were summarized. Results:A total of 21 literatures were included with 3 357 patients,of whom 1 580 underwent CPVI alone and 1 777 underwent CPVI combined with additional site ablation.The follow-up time was more than 1 year.Meta-analysis showed that there was no significant difference between CPVI alone and CPVI combined ablation strategies in reducing AF recurrence(OR=0.86,95%CI:0.73-1.01,P=0.06).Subgroup analysis based on additional ablation site,AF type,left atrial diameter,and AF diagnosis time showed that only in the small left atrial diameter subgroup,CPVI combined with additional ablation further reduced the recurrence rate of AF(OR=0.68,95%CI:0.47-0.98,P=0.04). Conclusions:The ablation strategy of CPVI combined with additional sites could not reduce the recurrence rate of AF compared with CPVI alone.

Objective:To summarize the characteristics of oral contrast ultrasound in patients with esophageal hiatal hernia (EHH), to screen the diagnostic criteria for EHH diagnosis by oral contrast ultrasound and to evaluate their diagnostic values.Methods:Sixty-one patients who visited the Hernia and Abdominal Wall Surgery Department of the Sixth Affiliated Hospital of Sun Yat-sen University from June 2023 to December 2023 for symptoms of acid reflux, heartburn, belching, recurrent epigastric pain, chest pain, and cough, and who were clinically suspected of EHH and underwent oral contrast ultrasound were retrospectively collected. The internal diameter of the esophageal hiatus, the length of the intraabdominal esophagus (IAEL), the angle of His, the supradiaphragmatic hernia sac, the sign of gastric wall sliding, and the sign of esophageal-gastric ring uplift were recorded by oral contrast ultrasound. All ultrasonographic data were retrospectively analyzed, and the diagnosis of EHH by surgery or with the simultaneous diagnosis of EHH by barium meal examination and gastroscopy were used as the gold standard. The diagnostic criteria of oral contrast ultrasound for EHH were obtained and their diagnostic values were evaluated by ROC curve analysis.Results:The indicators of EHH diagnosed by oral contrast ultrasound were analyzed according to ROC curves as follows: internal diameter of esophageal hiatus >15 mm (AUC=0.913), IAEL≤33 mm (AUC=0.776), angle of His > 90° (AUC=0.735), supradiaphragmatic hernia sac (AUC=0.913), gastric wall sliding sign (AUC=0.827), upward displacement of the esophagogastric ring (AUC=0.721). The diagnostic sensitivity, specificity, accuracy, positive predictive value, negative predictive value, AUC, and 95% CI of the diagnosis of EHH using the internal diameter of the esophageal hiatus >15 mm or the presence of a supradiaphragmatic hernia sac as the diagnostic criterion for the diagnosis of EHH by oral contrast ultrasound were 86.5%, 100%, 88.5%, 100%, 56.3%, 0.933, and 0.838-0.981, respectively. Conclusions:The optimal diagnostic criterion for EHH diagnosis by oral contrast ultrasound is esophageal hiatal internal diameter >15 mm or the presence of supradiaphragmatic hernia sac, which has 100% specificity and positive predictive value. It is recommended to be widely used as a screening test for EHH in the clinic.

AIM To investigate the clinical effects of Yiqi Shengjin Prescription on patients with primary Sj?gren's syndrome due to Dual Deficiency of Qi and Yin.METHODS Ninety-two patients were randomly assigned into control group(46 cases)for 8-week intervention of conventional treatment,and observation group(46 cases)for 8-week intervention of both Yiqi Shengjin Prescription and conventional treatment.The changes in clinical effects,TCM syndrome scores,ESSDAI score,ESSPRI score,salivary flow rate,immunoinflammatory indices(ESR,hs-CRP,IgG,C3,C4),SAS score,SDS score,T lymphocytes(CD4+,CD8+,Treg,Th17)and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the observation group exhibited decreased TCM syndrome scores(P＜0.05),which was lower than those in the control group(P＜0.05);the two groups displayed decreased ESSDAI score,ESSPRI score,ESR,hs-CRP,IgG,SAS score,SDS score,CD8+,Th17(P＜0.05),and increased salivary flow rate,C3,C4,Treg(P＜0.05),especially for the observation group(except for CD4+)(P＜0.05).No obvious adverse reactions were observable in the two groups.CONCLUSION For the patients with primary Sjogren's syndrome due to Deficiency of Qi and Yin,Yiqi Shengjin Prescription can safely and effectively improve dry mouth and eye symptoms,and reduce inflammatory indices,whose mechanism may contribute to the regulation of T lymphocyte balance in vivo.

OBJECTIVES: To study the protective effect of breviscapine against brain injury induced by intrauterine inflammation in preterm rats and its mechanism. METHODS: A preterm rat model of brain injury caused by intrauterine inflammation was prepared by intraperitoneal injections of lipopolysaccharide in pregnant rats. The pregnant rats and preterm rats were respectively randomly divided into 5 groups: control, model, low-dose breviscapine (45 mg/kg), high-dose breviscapine (90 mg/kg), and high-dose breviscapine (90 mg/kg)+ML385 [a nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor, 30 mg/kg] (n=10 each). The number and body weight of the live offspring rats were measured for each group. Hematoxylin-eosin staining was used to observe the pathological morphology of the uterus and placenta of pregnant rats and the pathological morphology of the brain tissue of offspring rats. Immunofluorescent staining was used to measure the co-expression of ionized calcium binding adaptor molecule-1 (IBA-1) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex of offspring rats. ELISA was used to measure the levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-1β (IL-1β) in the brain tissue of offspring rats. Western blotting was used to measure the expression of Nrf2 pathway-related proteins in the brain tissue of offspring rats. RESULTS: Pathological injury was found in the uterus, and placenta tissue of the pregnant rats and the brain tissue of the offspring rats, and severe microglia pyroptosis occurred in the cerebral cortex of the offspring rats in the model group. Compared with the control group, the model group had significant reductions in the number and body weight of the live offspring rats and the protein expression levels of Nrf2 and heme oxygenase-1 (HO-1) in the brain tissue of the offspring rats (P<0.05), but significant increases in the relative fluorescence intensity of the co-expression of IBA-1 and NLRP3, the levels of the inflammatory factors IL-6, IL-8, and IL-1β, and the protein expression levels of NLRP3 and caspase-1 in the brain tissue of the offspring rats (P<0.05). Compared with the model group, the breviscapine administration groups showed alleviated pathological injury of the uterus and placenta tissue of the pregnant rats and the brain tissue of the offspring rats, significant increases in the number and body weight of the live offspring rats and the protein expression levels of Nrf2 and HO-1 in the brain tissue of the offspring rats (P<0.05), and significant reductions in the relative fluorescence intensity of the co-expression of IBA-1 and NLRP3, the levels of the inflammatory factors IL-6, IL-8, and IL-1β, and the protein expression levels of NLRP3 and caspase-1 in the brain tissue of the offspring rats (P<0.05). The high-dose breviscapine group had a significantly better effect than the low-dose breviscapine (P<0.05). ML385 significantly inhibited the intervention effect of high-dose breviscapine (P<0.05). CONCLUSIONS Breviscapine can inhibit inflammatory response in brain tissue of preterm rats caused by intrauterine inflammation by activating the Nrf2 pathway, and it can also inhibit microglial pyroptosis and alleviate brain injury.

The prevalence of diabetes in China is increasing year by year， and has become a health issue of close concern to the whole society. Glucagon-like peptide-1 （GLP-1） receptor agonist （GLP-1RA）， as a new class of glucose-lowering drugs， is now widely used in the treatment of type 2 diabetes mellitus （T2DM） because of its significant glucose-lowering efficacy and low risk of hypoglycemia. As the level of evidence for its effects on improving cardiovascular system and renal protection and reducing body mass continues to improve， its status in the treatment guidelines for T2DM is gradually increasing. Currently， nine GLP-1RA drugs have been approved for the clinical treatment of T2DM in China. Although all of these drugs exert hypoglycemic effects based on the activation of GLP-1 receptors in the body， the differences in their own structures and natural GLP-1 amino acid homology lead to large differences in pharmacokinetic parameters and clinical efficacy among different analogs. In order to enable clinicians and pharmacists to have a full understanding of the characteristics and clinical evidence of these analogs and to better perform their therapeutic effects， Liaoning Provincial Pharmaceutical Society organized clinical medicine and pharmacy experts to develop a medication guide for nine GLP-1RA drugs to provide a reference for clinical medication needs and promote rational and standardized use by compiling and summarizing the pharmacological characteristics， clinical applications， adverse reactions， interactions， the medications in special populations and medication management.
