Objective:To explore the effect of ezetimibe combined with atorvastatin on the efficacy,blood lipids,ca-rotid ultrasound indicators in patients with coronary heart disease(CHD)and its safety.Methods:This randomized controlled study enrolled 98 CHD patients admitted to 945th Hospital of the PLA Joint Logistic Support Force be-tween June 2021 and June 2023.Patients were divided into intervention group and control group with 49 cases in each group.Patients in the control group was treated with atorvastatin-bascd routine medication comparing to those in intervention group receiving additional ezetimibe,both groups were treated for 90 d.Clinical efficacy,blood lipids,carotid ultrasound indicators,endothelial function indicators,and incidence of adverse reactions were compared between two groups.Results:Compared with patients in the control group,those in the intervention group had significant higher total effective rate(91.83％vs.73.47％,P=0.016).Compared with patients in the control group after treatment,those in intervention group had significant lower levels of low density lipoprotein cho-lesterol(LDL-C)[(2.74±0.61)mmol/L vs.(3.42±0.66)mmol/L],total cholesterol(TC)[(3.80±0.89)mmol/L vs.(4.69±1.02)mmol/L],triglyceride(TG)[(1.79±0.53)mmol/L vs.(2.35±0.62)mmol/L],re-sistance index(RI)[(52.02±6.32)％vs.(57.95±6.02)％],carotid intima-media thickness(IMT)[(0.91±0.17)mm vs.(1.08±0.24)mm],von Willebrand factor(vWF)[(19.03±3.76)mg/L vs.(23.41±4.42)mg/L],angiotensin Ⅱ(Ang Ⅱ)[(45.83±5.87)ng/L vs.(52.87±6.01)ng/L](P＜0.001 all);and significant high-er high density lipoprotein cholesterol(HDL-C)[(1.63±0.32)mmol/L vs.(1.35±0.27)mmol/L],peak systol-ic velocity(PSV)[(47.93±5.26)cm/s vs.(41.32±4.98)cm/s],end-diastolic velocity(EDV)[(36.14±5.10)cm/s vs.(30.73±4.48)cm/s],pulse index(PI)[(85.98±9.03)％vs.(78.42±8.82)％],vascular endothelial growth factor receptor 1(VEGFR1)[(289.14±32.98)ng/L vs.(258.34±29.32)ng/L](P＜0.001 all).There was no significant difference in the incidence of adverse reactions between the two groups(P=0.538).Conclusion:Ezetimibe combined with atorvastatin possesses significant therapeutic effect on CHD patients,which could signifi-cantly reduce blood lipids,improve the carotid blood flow velocity and vascular endothelial function with good safety.

Aim To analyze the effects of berberine on the apoptosis of colon epithelial cells and polymorpho-nuclear neutrophils ( PMNs) in mice with ulcerative colitis ( UC ) by regulating JAK/STAT signaling pathway. Methods The UC mouse models were established by dextran sulfate sodium ( DSS) method and were randomly divided into control group, UC group, low-dose, middle-dose and high-dose berberine groups and positive drug group ( mesalazine enteric-coated tablet group) . In addition, the mice were randomly di¬vided into UC group, high-dose berberine group, AG490 group, and high-dose berberine + AG490 group. Levels of serum tumor necrosis factor a (TNF-α) and interleukin 6 (IL-6) and colon epithelial cell apoptosis and PMN apoptosis were compared among the groups. Western blot was used to detect the expres¬sions of colon tissue apoptosis-related and JAK/STAT signaling pathway-related proteins. Results The lev¬els of serum TNF-α and IL-6, apoptosis rate of colon epithelial cell and protein expressions of Fas, FasL, Bax, caspase-3, p-JAK2/JAK2 and p-STAT3/STAT3 in each dose berberine group and positive drug group were significantly lower than those in UC group (P < 0.05), and the above indicators in berberine groups were reduced gradually (P <0.05) . The PMN apoptosis rate and Bcl-2 protein expression were significantly higher in each dose berberine group and positive drug group than those in UC group (P <0. 05) , and the two indicators increased gradually in berberine groups ( P < 0.05). AG490 could reverse the above effects of berberine ( P < 0. 05 ). Conclusions Berberine can inhibit the apoptosis of colon epithelial cell and promote the apoptosis of PMN in UC mice by regulating the JAK/STAT signaling pathway, and then play a role in the treatment of UC.

Objective To improve the knowledge of Kaposi sarcoma and the relationship between Kaposi sarcoma and human immunodeficiency virus (HIV) infection,and to improve the ability to diagnose and treat Kaposi sarcoma and acquired immune deficiency syndrome (AIDS).Methods Symptoms,signs and results of 121 patients encountered in the department of otorhinolaryngology head and neck surgery in Tanzania,who was diagnosed as Kaposi sarcoma actually with HIV infection and AIDS,were retrospectively analyzed in this study.Results There were 46 males and 75 females with age ranged from 5 to 65 years,medium 30 year.The mucous membranes and skin lesions was the most commonly seen clinical manifestation in 121 cases,these lesions appeared as raised blotches or lumps that might be purple,brown,or red,early stages typical lesions began as flat or slightly raised colored spots.Among the cases reported here,25 patients(20.66％)showed progressive nose blockage and nose bleeding and the purple-red new-grows were found in the nose of these patients.Fifteen patients (12.40％) had fiat or slightly raised colored spots in their mucous membrane of mouth (palate or tongue),and in other 7 patients,purple small lumps were found in the gums of the patients.There were same lesions in their pharynx in 9 cases.In 10 patients (8.26％),Kaposi sarcoma was found in tonsil looked like tonsillitis with enlarged tonsils by two to three degree.Twelve patients(9.92％) had masses in the neck with no pain.Thirty-five patients(28.92％)had lesions of purple black nodules,including 10 patients who had the same lesions with ulcer formation in the nodules.All patients had been followed-up for at least two-years.Eighty-five patients passed away in one year,survival rate of one year was 21.48％ (26/121),only 12 patients survived from the disease over two years,two years' survival rate was 9.92％ (12/121).Conclusions Kaposi sarcoma is the characteristic disease for AIDS,mainly found on the membranes and skin.These lesions appears as raised blotches or lumps that may be purple,brown,or red,early stages typical lesions begin as fiat or slightly raised colored spots.Patients who had kaposi sarcoma often died in a short-time without treatment.
