To enhance patients′ medical experience, a major Grade-A tertiary hospital has chosen its cardio-cerebrovascular disease branch with excellent specialty and prominent aging problems for innovative outpatient service systems. It created a comprehensive outpatient nursing post that integrated multiple departments of outpatient services, providing outpatient nursing services and related medical services such as outpatient office, medical insurance, and finance. By breaking the limitations of professional services, adjusting the outpatient service space, establishing standardized personnel training, assessment, and incentive mechanisms, and establishing an effective quality management system, the patients could complete all medical services without leaving the consultation area. The processing time for comprehensive patient services has been shortened from around 10 min to 1~5 min. In 2023, the complaint rate of the outpatients in the cardio-cerebrovascular disease branch was 0.89 times per 10 000 people, lower than the average of 1.37 times per 10 000 people in the entire hospital. The average satisfaction score of the outpatients from the branch was 93.9 points, higher than the 89.6 points of the entire hospital, achieving satisfactory results.

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Objective:To investigate the prevalence and the risk factors of Helicobacter pylori( H. pylori) infection in Qinghai Province with a multi-center cross-sectional study. Methods:From May to December in 2021, stratified sampling was conducted in Xining City, Haidong agricultural district, Hainan Tibetan Autonomous Prefecture, Haibei Tibetan Autonomous Prefecture and Yushu Tibetan Autonomous Prefecture by 20 centers, including the Affiliated Hospital of Qinghai University, Qinghai Red Cross Hospital and Qinghai Renji Hospital, etc. A questionnaire survey was carried out among the individuals undergoing routine health checkups. The questionnaire included general information, lifestyle and family history, etc. 13C-urea breath test was performed to diagnose H. pylori infection. Chi-square test, trend Chi-square test, segmentation method and multivariate logistic regression analysis were performed for statistical analysis. Results:The infection rate of H. pylori in Qinghai area was 53.6% (2 531/4 724). The age distribution of infection was statistically significant ( χ2=15.95, P=0.007), the infection rate in individuals aged 15 to<30 was higher than that of individuals aged 60 to< 75 (57.6%, 626/1 086 vs.49.5%, 231/467), and the difference was statistically significant ( χ2=8.83, P=0.003). With the increase of age, the infection rate decreased in female over 30 years old ( χ2trend=5.89, P=0.015). There were statistically significant differences in H. pylori infection rate among different ethnic groups ( χ2=28.13, P<0.001); the infection rate of Tibetan population was higher than that of Han population (62.9%, 313/498 vs. 51.5%, 1 804/3 503), and the difference was statistically significant ( χ2=22.56, P<0.001). The H. pylori infection rate in people living at an altitude >3 500 m was higher than that of people living at an altitude between 1 500 m and 3 500 m (61.8%, 327/529 vs. 52.5%, 2 204/4 195), and the difference was statistically significant ( χ2=16.25, P<0.001). Compared with those without corresponding habits, the infection rate of H. pylori was higher in smokers (62.1%, 1 081/1 740 vs. 48.6%, 1 450/2 984), in people who had the habit of eating hand grabbed mutton (55.4%, 967/1 744 vs. 52.5%, 1 564/2 980), raw garlic (55.5%, 968/1 744 vs. 52.4%, 1 563/2 980), spicy food (55.6%, 1 471/2 647 vs. 51.0%, 1 060/2 077), sweet food (55.2%, 1 187/2 149 vs. 52.2%, 1 344/2 575), the infection rate of tea drinkers was lower (50.5%, 1 135/2 247 vs. 56.4%, 1 396/2 477), and the differences were statistically significant ( χ2=80.94, 3.89, 9.63, 4.36, 4.13 and 16.19, all P<0.05). The results of logistic regression analysis indicated that Tibetan ( OR=1.379, 95% confidence interval (95% CI) 1.120 to 1.699), the Hui people ( OR=1.362, 95% CI 1.117 to 1.662), living at an altitude over 3 500 m ( OR=1.355, 95% CI 1.107 to 1.657), smoking ( OR=1.847, 95% CI 1.629 to 2.094), and spicy food ( OR=1.224, 95% CI 1.084 to 1.382) were independent risk factors of H. pylori infection (all P<0.05). Conclusions:The infection rate of H. pylori in Qinghai Province is higher than the average level in inland China. The infection rate of people with different ages, nationalities, altitudes of residence, occupations, living and eating habits were different. The infection rate of female over 30 years old is decreasing year by year. The infection risk is high in Hui people and Tibetan, spicy food lovers, smokers and people living at an altitude >3 500 m.

Objective To observe the inhibitory effect of pyridoxine hydrochloride (PN) combined with common chemotherapeutics on mice hepatoma cells H22 in vitro. Methods MTT assay was used to determine the effects of PN in combination with 10 different antineoplastic agents on H22 cells, and immuno-histochemistry was used to observe the distribution of PN in H22 cells and morphologic changes of the cells before and after PN treatment. Results After 24 hours incubation with 5 mmol/L PN, the treated cells expanded apparently with nucleus chipping. PN entered the tumor cell and was mainly condensed in cytoplasma and H22 cells were sensitive to PN. When administered concomitantly with chemotherapic agents, most of the combinations showed antagonistic effects while a few of the combinations were additive. For instance, doxorubicin (ADM) used in combination with PN inhibited cell proliferation with an IR value (IR=0.63) much lower than ADM alone (IR=0.71, P<0.01), and the CI value was less than 0.9, which indicated an antagonistic effect. However, PN in combination with ifosfamide (ICTX) showed additive effect (CI>0.9), and the IR value (IR=0.60) in combined group was higher than that (IR=0.40) in ICTX group (P<0.05). Conclusion PN treatment could increase the intracellular PLP level and result in growth inhibition and cell death, and combined administration of PN and ICTX might be a potential method to improve efficacy and to reduce toxic effects while a co-administration of PN and ADM should be avoided.

Objective To study the clinical efficacy of cell block yielded by ultrasound-guided fine needle aspiration in the early diagnosis of thyroid cancer and differential diagnosis of thyroid follicular tumor.Methods Cytological smears were performed in 864 thyroid nodules by ultrasound-guided fine needle aspiration.Then the residual specimens were made as cell blocks.Diagnosis was made by observation of the organization structure of the cell block.Cell block sections from 78 nodules with diagnosis of follicular tumors were applied to the detection of immunocytochemical staining for minichromosome maintenance protein (MCM2), growth arrest and DNA damage-induced nuclear protein 153 (GADD153), and Ki-67.Results Satisfaction rate of cytological smear combined with cell block specimen was 94.3 ％ (815/864) and accuracy rate of the diagnosis was 94.0％ (766/815), which were higher than in cytological smear group (P＜0.01).The false negative rate of cytological smear combined with cell block specimen was 16.6％ (41/247)in diagnosis of thyroid cancer.Positive rate of M CM2 and GADD153 in thyroid follicular neoplasia were lower than that of follicular carcinoma (P ＜ 0.01).There was no significant difference between thyroid follicular neoplasia and follicular carcinoma in regard to positive rate of Ki-67 (P ＞ 0.05).Conclusions The combination of ultrasound-guided fine needle aspiration-yielded cell block and molecular markers has great significance in early diagnosis of thyroid cancer and differentially diagnosis of thyroid follicular tumor.

Objective To identify the prevalence and etiology of kidney disease and the related risk factors in type 2 diabetic patients in rural Shanghai.Methods A cross-sectional study in type 2 diabetic patients was conducted in a community of Shanghai.Questionnaire,clinical examination and laboratory tests were completed to collect the information about sociodemographic and healthcare characteristics.Results A total of 1421 eligible patients with complete information were screened from 1487 type 2 diabetic patients between November 2008 and March 2009.Of them,40.75％ were men,59.25％ were women,aged 37-86 (61.33 ± 9.65 ) years old,with diabetic duration of 0.25-43.92 (7.85 ± 6.34) years.Among them,43.42％ had diabetic retinopathy,21.18％ had neuropathy; 69.95％ met the screening definition for hypertension,76.07％ for hyperlipidemia,15.55％ for hyperuricemia and 23.65％ for cardiovascular disease.The control rates of fasting blood glucose,glycosylated hemoglobin,blood pressure and serum cholesterol were 57.71％,33.99％,14.22％ and 2.46％,respectively.The prevalence of kidney disease,diabetic nephropathy and non-diabetic renal disease was 41.31％,18.51％ and 13.44％,respectively; and 9.36％ were diagnosed as renal insufficiency of unknown reasons.Age,diabetic duration,hyperuricemia,diabetic retinopathy and poor control of blood pressure were independently associated with kidney disease;age and poor control of blood pressure were independently associated with diabetic nephropathy; age and hyperuricemia were independent risk factors of renal insufficiency in patients with diabetic nephropathy.Conclusions Although the diabetic duration of these subjects is relatively short,the prevalence of complications including diabetic nephropathy is high.The high prevalence of non-diabetic renal disease shows the importance of further screening and diagnoses for prevention.Strict control of blood glucose,blood pressure,serum cholesterol and serum uric acid are key points of cutting down the prevalence of diabetic nephropathy and chronic kidney disease.

This study examined the anti-viral effect of ursolic acid on guinea pig cytomegalovirus (GPCMV) and explored the steps of viral replication targeted by ursolic acid. Cytopathic effect assay and MTT method were employed to determine the 50% cellular cytotoxicity (CC(50)), 50% effective concentration (EC(50)) and therapeutic index (TI) with GPCMV. To investigate the specific anti-viral effect of ursolic acid at different temperatures and time points, two other medicines, ganciclovir and Jinyebaidu (JYBD), serving as controls, were studied for comparison. Our results showed that the CC50 of ganciclovir, JYBD and ursolic acid were 333.8, 3015.6, 86.7 μg/mL, respectively; EC(50) of ganciclovir, JYBD and ursolic acid was 48.1, 325.5 and 6.8 μg/mL, respectively; TI of ganciclovir, JYBD and ursolic acid was 7, 9, 13, respectively. Similar with ganciclovir, ursolic acid could inhibit the viral synthesis, but did not affect the viral adsorption onto and penetration into cells. We are led to conclude that the anti-cytomegalovirus effect of ursolic acid is significantly stronger than ganciclovir or JYBD, and the cytotoxic effect of ursolic acid lies in its ability to inhibit viral synthesis.
