Shanghai Journal of Acupuncture and Moxibustion 2017;36(5):578-580
Objective To observe the clinical efficacy of PHENIX electrical stimulation in preventing complications after missed abortion.Method A thousand patients receiving uterine cavity operation on missed abortion were randomized into two groups, 500 cases in each group. Patients in the two groups were asked to orally take Estradiol valerate, successively for 3 d prior to the operation. Right after the operation, the treatment group started to receive electrical stimulation at Guanyuanshu (BL 26) and Guanyuan (CV 4) via PHENIX USB 4/8 neuromuscular stimulation therapeutic apparatus, together with conventional preventive anti-inflammatory treatment; the control group only received the conventional preventive anti-inflammatory treatment after the operation. The colporrhagia duration and the resumption of menstruation in the two groups were observed, and the menstruation, postoperative adhesion ratio and adhesion rate were compared between the two groups.Result There were significant differences in comparing the duration of colporrhagia and the time of the resumption of menstruation after the operation between the two groups (P<0.05); there were significant differences in comparing the postoperative menstruation, intrauterine adhesion ratio and adhesion rate between the two groups (P<0.05).Conclusion PHENIX electrical stimulation can shorten the time of colporrhagia after missed abortion, promote the resumption of menstruation, and effectively prevent intrauterine adhesions.

Objective To compare the clinical efficacy of endoscopic variceal ligation versus pericardial devascularization in the treatment of portal hypertension.Methods The clinical data of 101 cirrhotic patients with gastroesophageal varices and variceal hemorrhage from January 2010 to January 2012 were analyzed.Fifty-three patients received endoscopic variceal ligation,and forty-eight patients received pericardial devascularization.Postoperative changes in liver function and hypersplenism were compared between the two groups.The rate of rehaemorrhagia and incidence of postoperative complications after surgery were compared as well.Continuous data were expressed as mean ±SD,and categori-cal data were expressed as number of cases or percentage.Comparison of continuous data between the two groups was made by independent-samples t test,and comparison of categorical data was made by chi-square test.Results After surgery,the variceal ligation group showed no significant changes in liver reserve function,while the albumin level was significantly decreased in the pericardial devascularization group (t=2.512,P<0.05).There were no significant changes in the counts of white blood cells and platelets in the endoscopic variceal ligation group after surgery (P>0.05),but significant increases in the counts of white blood cells and platelets were detected in the pericardial devascular-ization group (P<0.05).The rates of postoperative haemorrhage in the two groups were:3 months,7.5%vs 6.2%(χ2 =0.066,P>0.05), 6 months,7.5%vs 8.3%(χ2 =0.021,P>0.05),and 1 year,9.4%vs 8.3%(χ2 =0.038,P>0.05).The incidence rates of postopera-tive complications in the two groups were 24.5%and 50%,respectively (χ2 =7.040,P<0.05).Conclusion Compared with pericardial devascularization,endoscopic variceal ligation causes fewer microlesions,preserves liver function,and leads to a lower incidence of postopera-tive complications.However,if hypersplenism is observed in the cirrhotic patients with gastroesophageal varices and variceal hemorrhage,peri-cardial devascularization can be used to control the hypersplenism and prevent esophageal hemorrhage.

Chinese Journal of Rehabilitation Theory and Practice 2004;10(7):406-407
Objective To study the protective effects of the compound with low molecular weight of anti free radical on brain ischemic and hypoxic injuries in rats.Methods The model of brain ischemic and hypoxic injuries in rats was established by unilateral carotid artery ligature just for 2 h. The compound was injected 30 minutes after the rats act on hypoxic state (10% O2+90%N2) for 1 h. Then the serum of rats was separated and the value of the superoxide dismutase (SOD) activity and malondiade (MDA) were determined, and the pathological changes were observed in brain tissue.Results Compared with rats in the model group, the compound decreased the concentrations of MDA in serum (P<0.05), and raised the level of SOD (P<0.05) significantly in therapy group. Otherwise, the pyramidal cells remained organized order, with only a few cells degenerated occasionally in rats of therapy group. Conclusion The compound has SOD like activity. It can scavenge the free radical and inhibit peroxidation of lipid, so it can prevent brain cells from the damage.

[Summary] The HK-2 cells with different culture media were divided into normal glucose group (NG group,5.5 mmol/L D-glucose) ; high glucose group (HG group,30 mmol/L D-glucose) ; mannitol group (MG group,5.5mmol/L D-glucose+24.5 mmol/L mannitol) ; 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3] groups (V1-V3 group)which were exposed to medium containing 30 mmol/L D-glucose and different concentrations of 1,25-(OH)2D3 ;Nethyl-cysteim control group (NAC group,30 mmoL/L D-glucose + 1.0 mmol/L N-Nethyl-cysteim) ; and ethanol control group(SG group,30 mmol/L D-glucose+6.86 × 10-2 mol/L ethanol).The level of intracellular reactive oxygen species,mitochondrial membrane potential,activity of total-superoxide dismutase (T-SOD),level of malondialdehyde,expression of UCP2 mRNA and protein in HK-2 cells were detected.Compared with NG group,the mitochondrial membrane potential significantly decreased in HG group (P<0.01),and the mitochondrial membrane potential in V group was lower than that in HG group(P<0.01).The activity ofT-SOD in HG group was significantly lower than that in NG group(P<0.01),while its level of malondialdehyde was significantly higher than that in NG group(P<0.01).Compared with HG group,the activity of T-SOD in V groups was significantly increased (P<0.05)and the level of malondialdehyde in these groups significantly decreased (P<0.01).The mRNA expression of UCP2 in HG group was increased significantly in comparison with NG group (P < 0.05) and the expression in V groups was significantly decreased in comparison with HG group (P<0.01).The results suggest that 1,25-(OH)2D3 could reduce the mitochondrial membrane potential,the production of reactive oxygen species,and regulate the expression of UCP2 in order to suppress the oxidative stress induced by high glucose.
