Objective:The study retrospectively analyzed the etiology, clinical manifestations, emergency treatment and etiological treatment of a large sample of cases with hypercalcemic crisis.Methods:The clincial data of patients with hypercalcaemia cirisis who were administered in First Medical Center of Chinese PLA General Hospital from January 2009 to July 2022 were analyzed, inculding the general data, clinical manifestations, etiology, photographic examination, emergency treatment, etiological treatment, serological examination before and after treatment, pathological immunohistochemical findings and prognosis.Results:A total of 143 hypercalcaemia crisis patients(84 males and 59 females) with a mean age of 53.51±16.60 were enrolled. The most common disease was hyperparathyroidism(62/143), followed by solid malignancy(57/143) and multiple myeloma(12/143). Patients presented with digestive system symptoms at 76.91%, followed by neurological symptoms at 63.60%, urinary system symptoms at 58.76%, musculoskeletal symptoms at 55.23%, and cardiovascular system symptoms at 32.91%. After emergency calcium-lowering treatment, the remission rate of hypercalcemic crisis in 143 patients was 100%(143/143), and after etiological treatment, the remission rate of hypercalcemia was 85.31%(122/143).Conclusion:Early identification, emergency treatment and etiology treatment of hypercalcaemia crisis are essential. Effective treament with comprehensive calcium reduction can quickly relieve clinical symptoms and create opportunities for treatment for the cause. Targeted etiological interventions can lead to the correction or long-term remission of hypercalcemia.

AIM: To explore the clinical features, diagnosis and treatment experience and the distribution characteristics of pathogenic microorganisms of primary canaliculitis, and provide reference for its diagnosis and treatment. METHODS: Retrospective clinical study. A total of 119 cases(120 eyes)diagnosed as primary canaliculitis in the department of ophthalmology of Wuxi No.2 People's Hospital from June 2019 to February 2023 were included. The treatment methods were mainly divided into conservative treatment(removing canaliculus stones through lacrimal punctum combined with injecting antibiotic eye ointment into the tube)and surgical treatment. The inspection methods of pathogenic microorganisms included secretion smear microscopy and microbial culture.RESULTS: Primary canaliculitis was more common in middle-aged and older female, mainly manifested by long-term red eye and increased secretion; however, the majority was not accompanied by tearing. Totally, 118 cases(99.2%)had monocular disease, while 63 cases(63 eyes; 52.5%)had inferior lacrimal canaliculus disease. Laboratory examination: Among 119 cases(120 eyes), 4 cases(4 eyes)did not undergo laboratory examination, and the other 115 cases(116 eyes)were as follows: Gram staining microscopy of secretion smear showed that Actinomyces were detected in 102 cases(103 eyes; 88.8%), while no fungus was detected; Microbial culture: 85 cases(86 eyes; 74.1%)were positive for bacterial culture. A total of 111 bacterial strains were cultured, which contained 26 types of bacteria. Among them, 32 strains were aerobic(28.8%); 26 strains were anaerobic(23.4%); and 53 strains were facultative anaerobic(47.7%). The most common bacteria were streptococcus(20 strains), staphylococcus(13 strains), Propionibacterium(10 strains), and capnocytophaga(10 strains). Only 4 cases(4 eyes; 3.4%)of microbial cultures were positive for Actinomyces. Fungus was negative in all microbial cultures. Treatment: Of the 119 cases(120 eyes), 114 cases(115 eyes; 95.8%)were cured by conservative treatment of removing lacrimal canaliculus stones through lacrimal punctum and intracanalicular ointment infiltration(IOI), while 5 cases(5 eyes)were not effective in conservative treatment; however, all of them were cured after surgical treatment, and the cure rate for primary canaliculitis was 100.0%.CONCLUSION: The incidence of primary canaliculitis is low, and it is prevalent in middle-aged and older female. Single lacrimal canaliculus is more common, which could be missed and misdiagnosed in clinic. Actinomyces is the major pathogen observed mostly in mixed infections, with heterogeneous strains, mainly anaerobic or facultative anaerobic bacteria. Streptococcus and Staphylococcus are the most common whereas fungal canaliculitis is rare. The cure rate of primary canaliculitis is high after diagnosis, and IOI method is recommended as the initial treatment of canaliculitis.

Objective:To establish ulcerative colitis(UC)rat model of spleen deficiency and dampness,and to explore effect of Jianpi-Huazhu pill and its different deconditions on TLR-4/MyD88/NF-κB pathway.Methods:A total of 64 Wistar rats were ran-domly divided into normal control group(n=8)and model group(n=56).UC rat model was established by traditional Chinese medi-cine syndrome combined with ethanol-2,4,6-trinitrobenzene sulfonic acid enema method.After successfully modeling,rats were ran-domly divided into model group(M),Mesalazine group(A),Jianpi-Huazhi pill group(B),Jianpi-Qinghua decoction group(C),Jianpi-Qinghua-Huoxue decoction group(D),Jianpi-Qinghua-Daozhi decoction group(E)and Qinghua-Daozhi-Huoxue decoction group(F),with 8 rats in each group,given corresponding drugs by gavage for 4 weeks.At end of course of treatment,all rats were sacrificed and samples were taken.Changes of body weight,disease activity and pathological changes of colon were observed.TNF-α expression in colon tissue was detected by ELISA and immunohistochemistry.RT-PCR and Western blot were used to detect mRNA and protein expressions of TLR-4,MyD88 and NF-κB in rat colon tissue.Results:Rats weight in Jianpi-Huazhi pill group,Jianpi-Qinghua decoction group,Jianpi-Qinghua-Huoxue decoction group and Jianpi-Qinghua-Daozhi decoction group were obviously higher than that of model group(P<0.01),all treatment groups could obviously improve UC model rat pathological damage and disease activity index in colon tissue,and Jianpi-Huazhi pill group and Jianpi-Qinghua-Huoxue group showed better efficacy.All treatment groups could inhibit mRNA and protein expressions of TLR-4,MyD88 and NF-κB in colon tissue(P<0.001).Mesalazine group,Jianpi-Huazhi pill group,Jianpi-Qinghua-Daozhi group and Qinghua-Daozhi-Huoxue group were significantly better than Jianpi-Qinghua group and Jianpi-Qinghua-Huoxue group in reducing NF-κB mRNA and protein expressions(P<0.05).All groups could reduce expres-sion of TNF-α in colon tissue(P<0.001),and there was no significant difference between groups(P>0.05).Conclusion:Jianpi-Huazhi pill and its various deconditions may play roles through TLR-4/MyD88/NF-κB pathway.Among them,Coptid-Rhizoma coptifo-lia,stews woody incense,Fengwei herb and gung ginger may be core drugs of this recipe,which has certain guiding significance for clinical practice.

Objective To explore the biliary tract microbiota changes before and after drainage treatment in patients with malignant biliary obstruction(MBO),and to study the effects of biliary obstruction and drainage intervention on the bile microbiota from a microecological point of view.Methods From January 2020 to December 2022,DSA-guided percutaneous transhepatic catheter drainage(PTCD)was carried out in 32 patients with MBO.A 22G drainage needle was inserted into the bile duct,and about 15-20mL of bile was extracted after it was confirmed that the needle was located within the intrahepatic bile duct,then,an external drainage tube,or an internal drainage tube together with an external drainage tube,was implanted into the bile duct along the guide wire.Seven days after PTCD,bile was extracted through a drainage tube.Bile sampling for germiculture and gene sequencing was conducted twice.The general data of patients,including whether acute cholangitis occurred and its severity,whether antibiotics was used for treatment,etc.,were collected.Results Of the 32 patients,cholangiocarcinoma was seen in 15,pancreatic cancer in 10,hepatocellular carcinoma in 3,and hilar lymph node metastasis from gastrointestinal malignant tumor in 4.Before PTCD,in the bile microbiota the burkholderia,acinetobacter,pseudomonas and staphylococcus were the bacteria with a high relative abundance,and the diversity and evenness of other microbial species seen in the normal biliary tract were reduced.Conclusion There is a stable microbiota within the normal biliary system,and in malignant obstructive biliary tract the microbiota has similar composition.After biliary drainage,the abundance of intestinal flora in bile is increased,and the species richness and diversity of the original biliary tract microbial community are decreased,which may explain the clinical phenomenon that patients are more prone to biliary tract infection after biliary drainage.(J Intervent Radiol,2024,33:516-522)

Objective To investigate the tendency of viral hepatitis in Changning District, Shanghai, and to provide scientific evidence for decision-making of prevention and control. Methods Cases of viral hepatitis in Changning District from 2009-2019 were collected , and the epidemiological characteristics of viral hepatitis were analyzed by descriptive epidemiological method. Joinpoint regression analysis were used to estimate the annual percent change and average annual percent change, and to perform the trend test. Results Among the 2009-2019 in Changning District, a total of 3 397 cases of viral hepatitis were reported , the annual average incidence rate was 49.32/100 000. Results from Joinpoint trend analysis indicated that the incidence of viral hepatitis in Changning District was mainly due to hepatitis A and hepatitis B. Conclusions Although the annual incidence rate of viral hepatitis in Changning District is far below the incidence rate of viral hepatitis in China, but it still shows an increasing trend. This shows that the situation of prevention and control of viral hepatitis in Changning is still serious, and hepatitis B remains the key point of prevention of viral hepatitis in Shanghai.

Objective:To explore the characteristics of the association between the triglyceride glucose (TyG) index and nonfatal cardio-cerebrovascular disease risk in a community population.Method:This was a prospective cohort study. From December 2011 to April 2012, the first investigation was conducted among subjects with more than 40-year old who were from Shijingshan district and Pingguoyuan community in Beijing. The second investigation was conducted from April to October 2015. All the subjects were divided into three groups according to the tertile of the TyG index at baseline. The multivariate Cox proportional risk regression model was established to explore the correlation between the TyG index and nonfatal cardio-cerebrovascular disease risk and the Kaplan-Meier survival curve of the TyG index group was drawn. Subgroup analyses were performed according to age, gender, body mass index, type 2 diabetes mellitus (T2DM), hypertension, and hyperlipidemia to determine the correlation characteristics between the TyG index and nonfatal cardio-cerebrovascular disease among subgroups.Results:A total of 9 577 subjects were finally included to analyze. The mean follow-up time of this study was (34.14±3.84) months. During the follow-up, 363 subjects (3.8%) occurred nonfatal cardio-cerebrovascular disease. The multivariate Cox regression analysis results showed that the hazard ratio ( HR) of nonfatal cardio-cerebrovascular disease in the high TyG index group was 1.54 (95% CI 1.19-1.98), 1.60 (95% CI 1.23-2.10), and 1.57 (95% CI 1.20-2.05) in the three models, compared with the low TyG index group. The Kaplan-Meier analysis showed that the risk of nonfatal cardio-cerebrovascular disease increased from the low-TyG index group to the high-TyG index group ( P=0.015). In the six subgroups analysis, only gender was shown to have a significant interaction effect with the TyG index and nonfatal cardio-cerebrovascular disease risk. In the female population, the risk of nonfatal cardio-cerebrovascular disease is significantly increased with the increase in the TyG index level ( P<0.001). Conclusions:A high TyG index is independently related to the increased risk of nonfatal cardio-cerebrovascular disease in the Beijing community population. Gender has a significant interaction with the TyG index and nonfatal cardio-cerebrovascular disease risk. Therefore, the TyG index may be a useful marker to predict the nonfatal cardio-cerebrovascular disease risk of a community population.

China’s chronic disease management suffers from problems such as unclear institutional function， insufficient information technology application， and weak regulation support. On the basis of current chronic disease management condition in China， this paper proposes to apply the concept of “people-centered” integrated health management to community chronic disease management and discusses the content and procedure of establishing an integrated community-based chronic disease management model driven by massive databases. The model innovatively combines technology integration， data integration and service integration， and can accurately and efficiently realize the "people-centered" full-course health management of various chronic diseases. Shanghai has provided integrated community-based chronic disease management service for 1.98 million citizens through applying this model. The model warrants further effectiveness and economic evaluation. This study provides precious experience for the development of chronic disease prevention and treatment in China.

Objective:To analyzed clinical characteristics of pituitary growth hormone(GH) adenomas patients with different responses to oral glucose inhibitory GH test.Methods:The clinical data of 50 patients with pituitary GH adenomas newly diagnosed with complete test data and case data in the Department of Endocrinology of Chinese PLA General Hospital was retrospectively analyzed from 2016 to 2021. The cases were divided into two groups according to the cutoff point of GH elevating to 50% of basaline during oral glucose test: abnormal elevation group(A group, n=16) and non-elevation group(B group, n=34). The clinical features, biochemistry, iconography, and immunohistochemistry of the two groups were analyzed. Results:The serum total cholesterol(TC)[(3.9±0.8) vs (4.6±0.9)mmol/L], 120 minutes insulin after glucose loading [11.2(4.4, 25.0) vs 92.0(10.8, 311.8)mU/L], long [1.0(0.4, 2.1) vs 1.5(0.5, 7.3) cm] and short[0.6(0.3, 1.3) vs 1.0(0.5, 5.8)cm] diameters of adenomas in A group were less than those in B group(all P<0.05) while insulin-like growth factor Ⅰ(IGF-Ⅰ) level was higher [(908.2±233.7) vs (743.1±273.1) ng/mL, P<0.05]. There were no significant differences in sex, age, disease course, clinical features, random GH, homeostasis model assessment of insulin resistance index(HOMA-IR), pituitary adenoma site, and invasive properties between the two groups. The immunohistochemical positive rates of ACTH(33% vs 0%) and prolactin(100% vs 28.6%)in A group were higher than those in B group( P<0.05). Conclusion:Pituitary GH adenomas patients with a paradoxical GH response pattern display lower serum TC and 120 minutes insulin levels as well as higher IGF-Ⅰ concentration and proportion of pituitary microadenomas. " Pure" growth hormone tumors may represent entities of a particular class of diseases in acromegaly.
