RESUMO
ObjectiveTo investigate the high-risk detection rate and aggregation of cardiovascular diseases（CVD） in 8 districts of Shanghai and influencing factors， and to provide scientific references for prevention and control of CVD. MethodsBased on the Cardiovascular Disease Screening and Management Program in Shanghai from 2016 to 2021， 104 685 participants aged 35 to 75 in 8 districts of Shanghai were selected for analysis. χ2 test and multivariate logistic regression were used for statistical analysis of the influencing factors of CVD and aggregation of CVD. ResultsThe proportion of high-risk CVD individuals in the population was 19.17%， including the high-risk individuals with hypertension （8.65%）， dyslipidemia （6.33%）， CVD history （5.58%）， and WHO assessed risk ≥20% types （2.69%）， respectively. Old age， overweight and obesity， central obesity， smoking， drinking， farmers， unmarried， and low family income were the risk factors of CVD， while high education level was the protective factor. In the participants， 16 323 people （81.34%） were classified as CVD high-risk groups； The number of aggregation of 1， 2 and ≥3 high risk types of CVD were 16 323（81.34%）， 3 236（16.13%）， 509（2.54%）， respectively. Old age， low education level， low annual family income， farmers， unmarried， smoking， drinking， overweight， obesity and central obesity were associated with the risk of aggregation of high risk types of CVD， and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension， elderly， overweight， obesity， central obesity， smoking， drinking， low educated， low family income， farmers and unmarried people， and targeted intervention measures should be taken to reduce the risk of CVD among residents.
RESUMO

In the following practice, we must continue to work on issues such as the improvement of teacher talent quality, the building of an efficient talent team, and the construction of practical application value evaluation systems for teaching.
RESUMO
Metformin is the preferred first-line drug by current global recommendation for the treatment of type 2 diabetes mel?litus. Drug safety of patients with chronic kidney disease(CKD)has always been the focus of concern,so treatment of CKD by metfor?min has always been controversial. Recent studies at home and abroad have found that metformin′s treatment of CKD is safe ,and the additional benefits far exceed the potential risks. The latest domestic and international guidelines also agree that CKD is not an abso?lute contraindication to metformin,and suggest relaxing the restriction of metformin for the treatment of mild and moderate renal insuf?ficiency,but the use of metformin for medium and severe renal insufficiency remains controversial. The latest research data and guide?lines about the safety of metformin′s treatment of CKD are reviewed in this article to provide a reference for clinical rational use of met?formin.

RESUMO
The enantiomers separation of thirteen drugs collected in Ch.P2010 was performed on chiral stationary phase of cellulose ramification (chiralpak OD and chiralpak OJ) by high performance liquid chromatographic (HPLC) methods,which included ibuprofen (Cl),ketoprofen (C2),nitrendipine (C3),nimodipine (C4),felodipine (C5),omeprazole (C6),praziquantel (C7),propranolol hydrochloride (C8),atenolol (C9),sulpiride (C10),clenbuterol hydrochloride (C11),verapamil hydrochloride (C12),and chlorphenamine maleate (C13).The mobile phase consisted of isopropanol and n-hexane.The detection wavelength was set at 254 nm and the flow rate was 0.7 mL/min.The enantiomers separation of these thirteen racemates on chiralpak OD column and chiralpak OJ column was studied,while the effects of proportion of organic additives,alcohol displacer and temperature on the separation were studied.And the mechanism of some of racemates was discussed.The results indicated that thirteen chiral drugs could be separated on chiral stationary phase of cellulose ramification in normal phase chromatographic system.The chromatographic retention and resolution of enantiomers could be adjusted by factors including column temperature and the concentration of alcohol displacer and organic alkaline modifier in mobile phase.It was shown that the resolution was improved with reducing concentration of alcohol displacer.When concentration of organic alkaline modifier was 0.2％ (v/v),the resolution and the peak shape were fairly good.Most racemates mentioned above had better resolution at column temperature of 25 ℃.When racemates were separated,the temperature should be kept so as to obtain stable separation results.
RESUMO
OBJECTIVE: To study the mechanisms of Tongxia Huayu Decoction (a Chinese herbal decoction for purgation and removing blood stasis) in prognostic improvement for severe acute pancreatitis by early intervention on pancreatic microcirculatory disturbance. METHODS: Fifty-three patients with severe acute pancreatitis were divided randomly into treatment group (n=28) and control group (n=25). Tongxia Huayu Decoction was given to the patients in treatment group in addition to the normal treatment in control group for one week. The clinical symptoms and signs, hemodiastase, urinary amylase, C-reactive protein (CRP) and endothelin (ET) of the patients in the two groups before and after treatment were observed and detected. RESULTS: The total response rate of the treatment group was 98.4%, while that of the control group was 80%, with significant difference between them (P<0.05). There was no significant difference of the contents of hemodiastase, urinary amylase, CRP and ET between the two groups before treatment, while they were significantly decreased after treatment (P<0.01) with more obvious change in treatment group (P<0.01). CONCLUSION: Tongxia Huayu Decoction brings satisfied therapeutic effect on severe acute pancreatitis. The mechanisms may associate with its reducing function on ET releasing so as to inhibit the pancreatic microcirculatory disturbance and acinar cell injury induced by ET.

RESUMO
Objective To study the clinical features of senile salivary gland neoplasms. Methods A total of 104 cases of senile (beyond 60 years old) salivary gland tumors treated in the past 15 years were analysed. Results Among the 104 cases of senile salivary gland tumors, benigns(85.6%) was more than malignants; males(76.0%) was more than females, the ratio of M∶F was about 1.5∶1. Seventy-two cases(69.2%) were from the parotid gland, 19 (18.3%) from the submandibular gland, 6 (5.8%) from the sublingual gland, 7 cases(6.7%) from the minor salivary gland. Warthin tumor (34 cases) accounted for 32.7%(34/104) of all senile salivary gland tumors, and 47.2%(34/72) of senile parotid gland tumors, 54.8%(34/62) of benign parotid gland tumors. Conclusions The senile salivary gland tumor were mainly benign tumor; Warthim tumor is the most commonly seen and the parotid gland is the most frequently targeted organ. The incidence in males is higher than in females, patients at 60-70 years old (76.0%) are the main victims. Regional excision of parotid gland (resection of tumor together with its surrounding glands) was efficient for surgical treatment in the elderly.
RESUMO
Objective To investigate the potential mechanism of inhibition of ursolic acid(UA) on growth of human gastric cancer cell lines SGC7901 in vitro.Methods SGC7901 cells were cultured in vitro,MTT assay was used to observe the effect of UA on growth of SGC7901 cells in various concentrations for different times.After SGC7901 cells were treated by 0—40 ?mol/L UA for 24 h,morphological changes were observed by inverted microscope.Apoptotic changes were detected by fluorescence microscopy and flow cytometry (FCM).Protein expressions of Bcl-2 and Bax were determined by Western blotting.Results UA(20—40 ?mol/L) could significantly inhibit the growth of SGC7901 cells in a(dose-and) time-dependent manner,the IC_(50) value of UA for SGC7901 cells for 12,24,36,and 48 h were((57.50?)1.18),(34.28?2.05),(27.54?1.11),and(24.83?1.02) ?mol/L,respectively.After UA((20—)40 ?mol/L) treatment for 24 h,SGC7901 cells turned round and floated at different levels;SGC7901 cells were arrested at G_0/G_1 phase and apoptosis was induced,and the apoptotic rate was increased along with the increase of UA concentration.Meanwhile Bcl-2 protein expression decreased,whereas Bax protein expression unchanged.Conclusion UA has a stronger antitumor effect on SGC7901 cells.Cytotoxic effect,proliferation inhibition,and apoptosis may be involoved in the mechanism of UA,and the apoptosis caused by UA may be enhanced by decrease of Bcl-2 protein expression.
