Objective To observe the clinical effect of oral use and acupoint application of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting in treating pregnant pernicious vomiting. Methods One hundred and twenty-two spleen-stomach deficiency pregnant pernicious vomiting cases were randomly divided into observation group ( N=63) and control group (N=59). At the end of the trial, 2 cases of the control group dropped out, and the total case number was 57 in the control group. Both groups were treated with intravenous infusion, dietary care, daily life and emotional nursing, and oral use of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. Additionally, the observation group was given acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. The treatment was performed once a day, 4 days constituted one treatment course, and the treatment lasted two continuous courses. The improvement of vomiting, therapeutic effect and the safety were compared between the two groups after treatment. Results ( 1) The total effective rate was 96.8%in the observation group and was 71.9%in the control group, the difference being significant (P<0.01). (2) The time for stopping vomiting in the observation group was significantly less than that in control group (P<0.01). (3) During the treatment, no obvious adverse reaction was found in the two groups. Conclusion Acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting has obvious synergistic effect on the clinical efficiency of spleen-stomach deficiency pregnant pernicious vomiting treated by oral use of herbal medicine, intravenous infusion, dietary care, and daily life and emotional nursing.

OBJECTIVE:To investigate the feasibility,safety and efficacy of domestic small waist big edge-type occluder for patients with multiple outlets sac-type membranous ventricular septal defection (VSD),and summarize its technical problems and the choice of treatment strategies.METHODS:A total of 20 patients with sac-type membranous VSD,underwent left ventricular angiography at left anterior oblique 45°-60° plus CAOD 20°-25°;the left ventricular entrance diameters were 7-21 (10.9±5.2) mm,more than 2 outlets in the right ventricular surfaces,and the largest outlet diameters were 3-10 (4.8±2.9) mm.According to the result from transthoracic echocardiography (TTE) and angiography,the sac-bag size,shape,location,extent of tissue adhesion,and stability were determined.Different types of small waist big edge-type occluder were implanted,and the occluder diameter was 5-14 (4.6±2.8) mm.Following 15 minutes of blocking,the immediate effects of occlusion were observed through repeating left ventricuiar angiography and TTE.All patients rechecked ultrasonic cardiography and electrocardiogram at 5-7 days of hospital stay,and 1,3,6 and 12 months following surgery.All patients took aspirin tablets for 6 months.RESULTS:Of 20 patients,17 cases underwent domestic small waist big edge occluder,blocked successfully through left ventricular entrance,2 cases were successful using symmetry block,and 1 case was failed.Intraoperative occlusion did not affect the aortic valve and tricuspid valve function.There were 1 case with left bundle branch block and 1 case with right bundle branch block during the operation,and all recovered within a week by using hormone therapy.After 6 months,the cardiac sizes were reduced to different degrees.CONCLUSION:It is safe and effective to treat multiple outlets sac-shaped membranous VSD with domestic small waist big edge-type occluder.The key technology,according to the sac size,shape,firmness,outlet orientation,import size,and the size of aortic stump,is to determine the block site and to select a suitable occluder.

Objective To investigate the mechanisms involved in cucurmosin-induced apoptosis of pancreatic cancer cell SW1990.Methods The expression of EGFR,PI3K,Akt,Bad,Caspase -9,mTOR,P70S6K-α,and 4E BP1 at the protein level were detected by western blot analysis,and RTPCR was used to determine EGFR mRNA expression.Results An increased concentration of cucurmosin showed a subsequent decrease in the expression of EGFR,PI3K,Akt,mTOR,P70S6Kα,and 4E -BP1,whereasthe expression of Bad and Caspase-9 were elevated.However,the mRNA expression of EGFR was unchanged.Conclusion Cucurmosin is shown to induce the apoptosis of pancreatic cancer cell SW1990 by down regulating the expression of EGFR and thus inactivating the PI3K/Akt/mTOR signaling pathway.

Objective:To explore the characteristics of nail fold microcirculation in hemodialysis patients and its correlation with cardiovascular events.Methods:The clinical data of 185 patients undergoing regular hemodialysis in Dongguan Donghua Hospital from January 2017 to December 2021 were retrospectively analyzed. Among them, there were 76 cases of cardiovascular events (cardiovascular events group) and 109 cases of no cardiovascular events (non-cardiovascular events group). The nail fold microcirculation detector was used to detect the nail fold microcirculation of the first row of capillaries in the nail fold dermal papilla of the left ring finger. The nail fold microcirculation indexes and morphology integral, flow integral, loop integral, total integral were recorded. The general information and laboratory indexes (peripheral venous blood) were recorded. The value of total integral of nail fold microcirculation in predicting the cardiovascular events in hemodialysis patients was evaluated using the receiver operating characteristics (ROC) curve.Results:The age, proportion of hypertension, proportion of diabetes, C-reactive protein (CRP), alkaline phosphatase and N-terminal pro-brain natriuretic peptide (NT-ProBNP) in cardiovascular events group were significantly higher than those in non-cardiovascular events group: 58 (44, 69) years vs. 49 (40, 63) years, 97.4% (74/76) vs. 83.5% (91/109), 43.4% (33/76) vs. 24.8% (27/109), 9.02 (2.73, 11.70) mg/L vs. 3.76 (1.28, 11.70) mg/L, 82 (75, 97) U/L vs. 72 (59, 82) U/L and 2 652 (1 020, 5 359) ng/L vs. 1 894 (780, 4 601) ng/L, the creatinine and triglyceride (TG) were significantly lower than those in non-cardiovascular events group: (961.95 ± 277.11) μmol/L vs. (1 058.93 ± 284.66) μmol/L and (1.73 ± 1.02) mmol/L vs. (2.27 ± 2.02) mmol/L, and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in gender composition, dialysis age, dialysis time, dialysis pathway, blood routine, serum iron, serum ferritin, total iron binding capacity, serum potassium, serum calcium, serum phosphorus, parathyroid hormone, urea nitrogen, albumin, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol between two groups ( P>0.05). There was statistical difference in erythrocyte aggregation between two groups ( P<0.05); there were no statistical differences in the number of vascular loops, diameter of input branch, diameter of output branch, length of loop, diameter of loop top, blood flow rate, clarity, condition of cross loop, condition of malformed loop, shape of nipple and subpapillary venous plexus between two groups ( P>0.05). The morphology integral and total integral in cardiovascular events group were significantly higher than those in non-cardiovascular events group: 1.8 (1.1, 3.1) scores vs. 1.4 (0.8, 2.5) scores and 4.2 (2.4, 6.1) scores vs. 3.1 (1.8, 5.2) scores, and there were statistical differences ( P<0.05); there were no statistical differences in flow integral and loop integral between two groups ( P>0.05). ROC curve analysis result showed that the area under the curve of the total integral of nail fold microcirculation for predicting cardiovascular events in hemodialysis patients was 0.590 (95% CI 0.506 to 0.673), the best cut-off value was 2.85 scores, the sensitivity was 69.7% and the specificity was 45.9%. Conclusions:The nail fold microcirculation disorder is more serious in hemodialysis patients with cardiovascular events. The nail fold microcirculation detection may help to predict cardiovascular disease.

Objective To evaluate the clinical efficacy of pre-procedure simethicone on detection of pharynx by upper gastrointestinal endoscopy. Methods A total of 100 patients with esophageal squamous cell carcinomas ( ESCCs) were enrolled in this prospective controlled trial and randomly assigned into two groups. The study group was given gargle with 5 mL simethicone plus 5 mL water combined with conventional procedure before gastroscopy. The control group was prepared according to the conventional procedure. The age, gender, tumor stage, lesion size, doctor＇s satisfaction and examination time between two groups were analyzed. Results The basic conditions between the two groups, including age, gender, and tumor stage were not significantly different (all P＞0. 05). The detection rate of superficial lesion in pharynx was higher in the study group than that in the control group, with no significant difference [8. 16%(4/49) VS 2. 04%( 1/49), P＝0. 362]. The median time of pharyngeal observation in the study group was less than that in the control group (21. 7 s VS 33. 9 s, P＝0. 000). The doctor was more satisfied in the study group than the control group (P＝0. 001). Conclusion Pre-procedure with simethicone improves the endoscopic visibility and detection rate of superficial squamous cell carcinoma with less observation time.
