Objective To analyze the efficacy of rosuvastatin on the patients with hyperlipidemia and hypertension.Methods From March 2011 to June 2012,112 cases with hyperlipidemia and hypertension in our hospital were enrolled in this study.Patients were randomly divided into treatment group and control group (56 patients,each).Patients in control group were treated with oral amlodipine 5 mg/d.Patients in treatment group were treated with oral rosuvastain 10 mg/d and oral amlodipine 5 mg/d.One month after the treatment,the levels of blood pressure,total cholesterol (TC),tryglyceride (TG),low density liporotein (LDL-C),high density lipoprotein cholesterol (HDL-C),high sensitivity C-reactive protein (hsCRP) were determined.The occurrence of adverse effects were observed.Results One month after treatment,systolic blood pressure and diastolic blood pressure were significantly decreased in both two groups compared with pre-treatment [Control group:(135.2±9.51)mm Hgvs.(59.2±7.3)mm Hg,(88.8±5.2)mm Hg vs.(99.5±8.3)mm Hg,t=4.95,2.87; Treatment group:(130.2±5.5)mm Hg vs.(160.3±9.3)mm Hg,(86.7± 10.2)mm Hg vs.(99.7±8.3)mm Hg,t=5.03,2.94,all P＜0.01],but more declines were found in treatment group than in control group(t=3.96,3.42,both P＜0.001).The levels of LDL-C,TG and TC were significantly decreased in both two groups compared with pre-treatment [Control group:(2.64±0.72)mmol/L vs.(3.97±0.84)mmol/L,(1.89±0.25)mmol/L vs.(2.56±0.45)mmol/L,(4.23±0.56)mmol/L vs.(7.36±0.48)mmol/L,t=2.58,3.03,2.36,P=0.013,0.004,0.022;Treatment group:(1.75 ± 0.68) mmol/L vs.(3.85 ± 0.79) mmol/L,(1.71 ± 0.18) mmol/L vs.(2.63±0.42)mmol/L,(3.18±0.47)mmol/L vs.(7.20±0.56)mmol/L,t=2.77,3.16,2.59,P=0.008,0.003,0.012,respectively],but more declines were observed in treatment group than in control group(t=6.73,4.37,10.70 respectively,all P＜0.05).The HDL-C concentrations were increased in both two groups compared with pre-treatment [Control group:(0.97±0.26)mmol/L vs.(0.75±0.31)mmol/L,t=2.89,P=0.006; Treatment group:(1.09±0.23)mmol/L vs.(0.72±0.24)mmol/L,t=3.01,P=0.004],but more increment were observed in treatment group than in control group(t=2.59,P＜0.05).The hsCRP concentration was significantly reduced in treatment group compared with pre-treatment [(1.32±0.17) mg/L vs.(4.97±0.13) mg/L,t=4.40,P＜0.001].There were no significant differences in liver and kidney function between the two groups.Serious adverse effects were not found.Conclusions Rosuvastatin combined with routine antihypertensive therapy can effectively decrease the levels of serum LDL-C,TG,hsCRP; increase serum HDL-C concentration and blood pressure can be effectively controlled.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.

Objective:To investigate the surgical method and therapeutic effect on repairing soft tissue defects around ankle with lateral tarsal artery island flap.Methods:From July 2013 to December 2020, the lateral tarsal artery island flap were used to repair the soft tissue defects around ankle in 12 patients in Hand Surgery Department, Jiangnan Hospital Affiliated to Binjiang College. Of which, 6 patients had soft tissue defects complicated with bone or tendon exposure after injury and 6 had skin necrosis with internal fixation after fracture. The area of soft tissue defects was 6.0 cm×4.0 cm-9.0 cm×5.0 cm, and the size of the flaps was 7.0 cm×5.0 cm-10.0 cm×6.0 cm. After the flap was freed, the vascular pedicle was separated up to the origin of dorsalis pedis artery. As the pedicel was not long enough in 1 patient, the dorsal pedis artery was ligated and transected at the origin of the lateral tarsal artery. Full thickness skin graft was used to repair the donor sites. The patients were treated with anti-infection and anticoagulant therapies. The postoperative follow-ups were conducted by outpatient clinic visit, telephone or WeChat interviews or home visit to observe the recoveries in texture, appearance, sensation, donor site and function of ankle.Results:All the flaps and skin grafts survived. The wound healed well without occurrence of ulcer. The follow-up ranged 6-108 months (mean 17 months). Appearance of the flaps was good. It was not bloated and the sensation was restored to S 2-S 3. Conclusion:It is a good method to apply the lateral tarsal artery island flap in repair of the soft tissue defects around ankle. It features a hidden donor site, simple operation and the high level of safety. The texture and appearance of the flap are close to those of the recipient site.

Objective:To explore the effects of the intervention program for intestinal dysfunction after spinal cord injury during the acute spinal cord injury period.Methods:Totally 76 patients with intestinal dysfunction during acute spinal cord injury who were admitted into Shanghai Sixth People's Hospital and Shanghai Changzheng Hospital between March and December 2019 were selected by convenient sampling. According to the non-concomitant controlled study design, 42 patients admitted from March to May 2019 were included into the control group, while 34 patients admitted from October to December 2019 were included into the intervention group. Patients in the control group received routine care, while the intervention program for intestinal dysfunction after spinal cord injury was adopted for patients in the intervention group. After 2 weeks of intervention, the intestinal function indicators were compared between the two groups.Results:After 2 weeks of intervention, the improvement of abdominal distension and constipation of the intervention group was better than that of the control group, and the difference was statistically significant ( P< 0.05) . Conclusions:The intervention program for intestinal dysfunction during acute spinal cord injury can effectively improve the intestinal function of patients and reduce the incidence of abdominal distension and constipation.

OBJECTIVETo develop a high-performance liquid chromatography (HPLC) method for the simultaneous determination of rutin, hyperoside, isoquercetin, astragulin, quercetin, and kaempferol in Apocynum venetum and its extracts.

METHODThe separation was carried out on a Shim pack ODS (4.6 mm x 250 mm, 5 microm) colum eluted with in mobile phases of water containing 0.2% phosphoric acid and acetonitrile containing 0.2% phosphoric acid in acetonitrile gradient mode. The column temperature was 40 degrees C, and the flow rate was 1.0 mL x min(-1). The detection wavelength was set at 360 nm.

RESULTThe good seperation of six flavonoids was achieved within 40 min, with the relative standard deviations (RSD) of intra- and inter-day precision < or = 2.0%. Calibration curves of rutin, hyperoside, isoquercetin, astragulin, quercetin, and kaempferol showed good linear relationship (R2 > 0.999 7, n = 6). The average recoveries of the six flavonoids were within 97.30% - 105.8% (RSD 2.6%). Three batches of A. venetum and 2 batches of its extracts were determined.

CONCLUSIONThe developed method is simple, accurate, and repeatable, and can be readily used as a powerful tool for the quality control of A. venetum and its extracts.

Objectives:To compare the effects of manual and mechanical chest compression on patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Patients who underwent extracorporeal cardiopulmonary resuscitation admitted to Jinhua Municipal Central Hospital, Hangzhou First People's Hospital and the First Hospital of Jiaxing from September 2014 to July 2022 were enrolled in the study. The patients were divided into the manual group and mechanical group according to the compression method, and the clinical data of the two groups were compared. To explore the effects of the two compression method on the ECPR implementation, proportion of return of spontaneous circulation (ROSC) and hospital survival.Results:A total of 108 patients who underwent ECPR were included in the study, 50 patients in the manual group and 58 patients in the mechanical group. There were no significant differences in sex, age, laboratory tests before ECPR, ROSC proportion (90.0% vs. 86.2%) and survival (34.0% vs. 39.7%) between the two groups (all P>0.05). The puncture time in the mechanical group was shorter than that in the manual group [12 (9,15) min vs. 13 (11,16) min, P<0.05]. Conclusions:Compared with manual compression, mechanical compression during ECPR neither increase the probability of ROSC nor reduce in-hospital mortality in patients with cardiac arrest. However, mechanical compression may help to shorten the puncture time.

Objective:To explore the expression level and clinical significance of serum Hsa_circ_0089761 in patients with cervical cancer.Methods:A total of 107 cervical cancer patients, 80 cervical intraepithelial neoplasia (CIN) patients, and 60 normal control group were selected and analyzed from January 2021 to March 2023 at the Ninth Affiliated People's Hospital of Shanghai Jiao Tong University School of Medicine. We compared the levels of serum Hsa_circ_0089761, squamous cell carcinoma antigen (SCCA), and carcinoembryonic antigen (CEA) among different groups, and analyzed the relationship between the expression level of serum Hsa_circ_0089761 and the clinical and pathological characteristics of cervical cancer. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of serum Hsa_circ_0089761, SCCA, and CEA levels for cervical cancer. Pearson correlation analysis was used to evaluate the correlation between serum Hsa_circ_0089761 expression levels and SCCA and CEA in cervical cancer patients.Results:The expression levels of serum Hsa_circ_0089761[(2.96±0.95) vs (1.83±0.74), (0.92±0.41)], SCCA[(9.63±1.84)ng/ml vs (2.28±0.65)ng/ml, (1.30±0.27)ng/ml], and CEA[(6.47±2.20)ng/ml vs (1.61±0.57)ng/ml, (1.15±0.12)ng/ml] in the cervical cancer group were significantly higher than those in the CIN group and the control group (all P<0.001), and the serum Hsa_circ_0089761 expression levels in the CIN group were significantly higher than those in the control group ( P<0.001). Cervical cancer patients in stages Ⅲ-Ⅳ, with low differentiation, lymph node metastasis, infiltration depth ≥1/2 of the muscle layer, positive SCCA, and positive CEA had significantly higher levels of serum Hsa_circ_0089761 expression (all P<0.05). The ROC curve analysis showed that the specificity of diagnosing cervical cancer was highest (85.00%) for Hsa_circ_0089761 ≥2.25, and the area under the ROC curve (AUC) for diagnosing cervical cancer in combination with SCCA was highest (0.932, 95% CI: 0.874-0.993), with the highest accuracy (89.30%). The sensitivity of the combination of Hsa_circ_0089761+ SCCA+ CEA in diagnosing cervical cancer was highest (96.26%). The correlation analysis results showed that the serum Hsa_circ_0089761 expression levels in cervical cancer patients were positively correlated with SCCA ( r=0.775, P<0.001) and CEA ( r=0.613, P<0.001). Conclusions:The expression level of serum Hsa_circ_0089761 in cervical cancer patients is significantly increased, which is related to clinical and pathological characteristics. The combination of Hsa_circ_0089761 and SCCA detection has high value in the diagnosis of cervical cancer.

Objective:To explore the efficacy and safety of high-titer plasma in the treatment of pediatric patients with severe adenovirus pneumonia.Methods:The clinical data of 92 pediatric patients with severe adenovirus pneumonia admitted to pediatric intensive care unit (PICU) in Guangzhou Women and Children′s Medical Center from January 2016 to October 2019 were retrospectively collected. According to the treatment with or without high-titer plasma, the patients were divided into plasma treatment group ( n=41) and non-plasma treatment group ( n=51). The 51 patients with chest radiograph showing more than half the lungs involved were divided into plasma treatment group ( n=29) and non-plasma treatment group ( n=22). According to fever duration before plasma treatment, patients were divided into early group (≤5 days, n=5), middle group (>5-10 days, n=14), and late group (>10 days, n=22). Baseline data, therapeutic effects, and prognosis of patients in each group were analyzed with t test, non-parametric rank sum test, one-way ANOVA and chi-square test. Results:Ninety-two patients were included. There were no significant differences in age, gender, body weight, fever duration, sequential organ failure assessment, and Murray lung injury score between plasma treatment group and non-plasma treatment group before admission (all P>0.05). The proportion of patients whose temperature drop to normal within 5 days was higher in plasma treatment group than that in non-plasma treatment group (88% (36/41) vs. 69% (35/51), χ 2=4.745, P=0.029). However, there were no significant differences between the two groups in the proportions of invasive ventilator weaning within 14 days (63% (26/41) vs. 76% (39/51), χ 2=1.868, P=0.172), transfer out from PICU within 14 days (49% (20/41) vs. 69% (35/51), χ 2=3.724, P=0.054), discharge within 28 days (51% (21/41) vs. 61%(31/51), χ 2=0.846, P=0.358) and survived patients (85% (35/41) vs. 76%(39/51), χ 2=1.143, P=0.285). Among patients with severe chest radiograph, the proportions of patients whose temperature drop to normal within 5 days and survived patients were higher in plasma treatment group than those in non-plasma treatment group (86% (25/29) vs. 59% (13/22), χ 2=4.843, P=0.028; 83% (24/29) vs. 55%(12/22), χ 2=4.796, P=0.029, respectively). However, there were no significant differences between the two groups in the proportions of invasive ventilator weaning within 14 days (52% (15/29) vs. 59% (13/22), χ 2=0.274, P=0.601), transfer out from PICU within 14 days (34% (10/29) vs. 45% (10/22), χ 2=0.632, P=0.427), and discharge within 28 days (45% (13/29) vs. 45% (10/22), χ 2=0.002, P=0.964). Among early, middle and late group, the proportions of invasive ventilator weaning within 14 days were 2/5, 13/14 and 50% (11/22), respectively, with statistically significant difference (χ 2=8.119, P=0.017). There were no significant differences in the proportions of patients whose temperature drop to normal within 5 days (4/5, 14/14, 82% (18/22), χ 2=2.965, P=0.227), transfer out from PICU within 14 days (2/5, 10/14, 36%(8/22), χ 2=4.386, P=0.112), discharge within 28 days (2/5, 8/14, 50% (11/22), χ 2=0.462, P=0.794) and survived patients (4/5, 13/14, 82% (18/22), χ 2=0.966, P=0.617) in the three groups. Only one case with high-titer plasma therapy had rash in the course of infusing plasma and no other adverse reactions were observed. Conclusions:High-titer plasma can shorten the fever time and improve the proportion of survival patients in pediatric severe adenovirus pneumonia. The clinical effect of high-titer plasma is better in 5-10 days of fever course. High-titer plasma is an effective and safe treatment.
