This article systematically analyzed the historical evolution of the origin， scientific name， producing area， quality evaluation， harvesting and processing， and other aspects of Quisqualis Fructus by consulting the ancient materia medica， medical books， prescription books， local literature and combining with the modern literature and standards， summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes， in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty， and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty， which has been consistently used throughout subsequent dynasties， and there were also aliases such as Junziren， Sijunzi， and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica， a plant belonging to the family Combretaceae. In modern times， its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007， the Flora of China（English edition） designated Q. indica var. villosa as a synonym of Q. indica. Today， the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records， the producing areas of Quisqualis Fructus were Guangdong， Hong Kong， Macao， Guangxi， Hainan， Sichuan and Fujian， and then gradually expanded to Yunnan， Taiwan， Jiangxi and Guizhou. Since the Song dynasty， two major production regions have gradually emerged in Sichuan， Chongqing and Fujian. Currently， it is primarily cultivated in Chongqing， Guangxi and other areas， with Chongqing yielding the highest output. Since modern times， superior quality has been defined by large size， a purple-black surface， plump grains， and a yellowish-white kernel. According to ancient herbal records， the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar， mostly used raw after shelling or with the shell intact， it underwent processing methods such as cleaning， slicing， mixing， steaming， roasting， stewing， and frying. Currently， the harvesting period is autumn， followed by sun-drying or low-heat drying， with processing methods including cleaning， stir-frying， and stewing. In ancient and modern literature， the records of the properties， functions and indications of Quisqualis Fructus are basically the same， that is， sweet in taste， warm in nature， predominantly non-toxic， belonging to the spleen and stomach meridians. It possesses effects of insecticide， decontamination and invigorating spleen for ascariasis， enterobiasis， abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations， limiting use for those with spleen-stomach deficiency-cold， refraining from drinking hot tea during medication， and avoiding excessive intake. Based on the textual research， it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements， and the raw products is recommended for medicinal use if not specified.

As the understanding of the pathogenic mechanisms of gastric cancer deepens and the identification of gastric cancer driver genes advances,drugs targeting gastric cancer driver genes have been applied in clinical practice.Among them,trastuzumab,as the first targeted drug for gastric cancer,effectively inhibits the proliferation and metastasis of tumor cells by targeting overexpressed human epidermal growth factor receptor 2(HER2).Trastuzumab has become the standard treatment for HER2-positive gastric cancer patients.Ramucirumab,on the other hand,inhibits tumor angiogenesis by targeting vascular endothelial growth factor receptor 2(VEGFR2)and has been used as second-line therapy for advanced gastric cancer patients.In addition,bemarituzumab targets overexpressed fibroblast growth factor receptor 2(FGFR2),while zolbetuximab targets overexpressed claudin 18.2(CLDN18.2),significantly extending progression-free survival and overall survival in patients with gastric cancer in clinical trials.This article reviews the roles of tumor driver genes in the progression of gastric cancer,and the treatment strategies for gastric cancer primarily based on targeting HER2,VEGF,FGFR2,CLDN18.2 and MET.This provides a reference for clinical application of targeted therapy for gastric cancer.

The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Objective:To investigate the effects of the interaction between ubiquitin-specific peptidase 22 (USP22) and hepatitis B virus X protein (HBx) on the protein level and the biological function of HBx.Methods:The interactions between HBx and USP22 were analyzed by GST pull-down, co-immunoprecipitation assay and confocal laser scanning assay. USP22 recombinant plasmids or specific siRNA were transiently co-transfected with HBx plasmids. Western blot were used to detect the protein level of HBx. The half-life and degradation pathway of HBx in the transfected cells treated with cycloheximide (CHX) or proteasome inhibitor MG132 were detected. In vivo ubiquitination assay was used to detect the ubiquitination of HBx with USP22 overexpression. Moreover, dual-luciferase reporter assay and colony formation assay were used to analyze the effects of USP22 on the biological function of HBx. Results:USP22 could interact with HBx in vivo and in vitro. USP22 significantly increased the stability of HBx and inhibited the proteasome-mediated degradation of HBx protein by reducing the ubiquitination of HBx, thereby enhancing the biological function of HBx. Conclusions:USP22 inhibited HBx protein degradation through ubiquitin-dependent proteasome pathway, thus enhancing the stability and biological function of HBx.

Objective: The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated. Methods: Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check. Results: (1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01). Conclusions There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.

ObjectiveTo investigate the clinical features of cholestatic liver disease (CLD), and to provide a reference for strengthening the diagnosis and treatment of this disease. MethodsA retrospective analysis was performed for the clinical data of 107 patients who were admitted to Chenggong Hospital Affiliated to Xiamen University from January 2015 to December 2017 and were diagnosed with CLD. The t-test was used for comparison of continuous data between groups. ResultsMost patients had the clinical symptoms of weakness, loss of appetite, nausea, abdominal distension, pruritus, and jaundice. According to the site of cholestasis, there were 64 patients (59.8%) with intrahepatic cholestasis and 43 (40.2%) with extrahepatic cholestasis. The cause of the disease was common bile duct stones in 21 patients (19.6%), bile duct parasites in 1 patient (0.9%), primary sclerosing cholangitis in 2 patients (1.9%), primary biliary cirrhosis in 3 patients (2.8%), liver cancer in 8 patients (7.5%), bile duct carcinoma in 5 patients (4.7%), pancreatic cancer in 4 patients (3.7%), pancreatitis in 12 patients (11.2%), viral hepatitis in 28 patients (26.2%), drug-induced liver injury in 11 patients (10.3%), alcoholic hepatitis in 6 patients (5.6%), nonalcoholic fatty liver disease in 4 patients (3.7%), and autoimmune hepatitis in 2 patients (19%). The CLD patients with underlying diseases had a significantly poorer liver function (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, bile acid, and total bilirubin) than those with CLD alone (t=-3.44, -2.99, -2.42, -4.39, -3.34, and -2.49, all P＜0.05). Most of the patients achieved good recovery after liver-protecting, transaminase-lowering, and jaundice clearance treatment. The patients with tumors had poor prognosis. ConclusionCLD has various causes, and its clinical features lack specificity. Clinicians should pay enough attention to this disease.

Objective To investigate the distribution and drug resistance to pathogenic bacterial pathogen in children with community acquired pneumonia (CAP),so as to provide recommendations for clinical rational use of anti-biotics. Methods A retrospective analysis was made on the distribution and drug resistance to bacteria in CAP chil-dren admitted to Department of Respiration,Shanghai Children′s Medical Center from January 2014 to December 2015. Results There were 463 patients with positive sputum culture,and a total of 496 strains of pathogens were found. There were 273 Galanz negative bacteria,195 Galanz positive bacteria and 28 other rare bacteria,accounted for 55. 04％,39. 31％ and 5. 65％ of the total bacteria,respectively. The main pathogens were Streptococcus pneumoniae, Staphylococcus aureus,Haemophilus influenzae,Klebsiella pneumoniae and Escherichia coli. The highest detection rate of bacteria in 1-12 months children with CAP was Staphylococcus aureus,Klebsiella pneumoniae and Escherichia coli;in > 12 months children with CAP,the highest detection rate of bacteria was Streptococcus pneumoniae,Haemophilus influenzae and Staphylococcus aureus. Both of Streptococcus pneumoniae and Staphylococcus aureus had a high resis-tance to Erythromycin,Clindamycin and Oxacillin. There were 11. 00％ Streptococcus pneumoniae and 94. 74％ taphy-lococcus aureus resistant to Penicillin,while they were not resistant to Vancomycin. Escherichia coli and Klebsiella pneumoniae both showed a high resistance to ampicillin,the second and third generation cephalosporins. Haemophilus influenzae were highly resistant to Compound sulfamethoxazole and Ampicillin. Galanz negative bacteria had the lowest resistance to Piperacillin/ Tazobactam and Amikacin. Conclusions The main pathogens of CAP in children were G -bacteria. There were some differences among the isolates at different ages of CAP. Their resistance to very common anti-biotics was very high in children.
