OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).

METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.

RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.

CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

AIM:To investigate the effects of high plasma triglyceride (TG) caused by apolipoprotein C Ⅲ( ApoC Ⅲ) transgene on the occurrence and development of abdominal aortic aneurysm ( AAA) .METHODS:The animal models of hypercholesterolemia and hypercholesterolemia combined with hypertriglyceridemia were established by feeding high-fat diet to LDLR-/-and ApoC Ⅲ+LDLR-/-mice, respectively.AAA was induced in these mice by pancreatic elastase. By evaluating the incidence of AAA, relative maximal abdominal aortic diameter, disruption of the elastic lamellar structure and expression of matrix metalloproteinases ( MMPs) in the aorta walls of the AAA, the occurrence and development of AAA were compared in LDLR-/-and ApoC Ⅲ+LDLR-/-mice fed with either chow diet or high-fat diet.In addition, an in vitro TNF-α-induced aneurysmal microenvironment model on vascular smooth muscle cells ( VSMC) was used to study the impact of triglyceride-rich lipoproteins ( TRLs) from mice with normal or high contents of ApoCⅢon elastin protein expres-sion.RESULTS:Feeding the high-fat diet aggravated the severity of AAA in the LDLR-/-mice.ApoC Ⅲ+LDLR-/-mice fed with high-fat diet had less severe AAA than LDLR-/-mice fed with high-fat diet.TRLs inhibited degradation of VSMC elas-tin protein induced by TNF-α, and in vitro TRLs from the mice with high content of ApoC Ⅲ, compared to those with nor-mal content of ApoC Ⅲ, had better inhibitory effect on the degradation of elastin.CONCLUSION:High plasma TG caused by ApoC Ⅲtransgene alleviates AAA of the LDLR-/-mice induced by elastase and high-fat diet.The effect is probably attrib-uted to the hypertriglyceridemia caused by ApoC Ⅲtransgene.

OBJECTIVETo observe changes of gonad functions of Gan-qi stagnation (GS), Pi deficiency (PD), Gan-qi stagnation Pi deficiency (GSPD) model rats, and the effect of Chaishu Sijun Decoction (CSD) on them.

METHODSRats were randomly divided into 7 groups according to romdom digit table, i.e., the normal control group, the GS model group, the GS medication group, the PD model group, the PD medication group, the GSPD model group,and the GSPD medication group, 10 in each group. Rats in the GS model group, the PD model group, and the GSPD model group were treated with chronic restraint, improper diet +excessive fatigue, chronic restraint +improper diet +excessive fatigue. The model was established for 4 successive weeks. Starting from the 15th day of modeling, CSD at the daily dose of 3.57 g/kg was given by gastrogavage to them for 14 successive days. Equal volume of distilled water was given by gastrogavage to rats in each model group and the normal control group for 14 successive days. The blood contents of gonadotrophin releasing hormone (GnRH), follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and testosterone (T) were detected in rats of each group.

RESULTSCompared with the normal control group, there was statistical difference in GnRH, T, E,, and FSH in the GS, PD, and GSPD model groups (P < 0.05, P < 0.01). The content of LH was elevated in the GS model group (P < 0.05) and declined in the GSPD model group (P < 0.01). Compared with the GS model group, the contents of FSH, LH, and T decreased and E2 increased in the PD model group (all P < 0.05); the contents of FSH and LH also declined in the GSPD model group (P < 0.05). Compared with the PD model group, the T content increased and FSH decreased in the GSPD model group (all P < 0.05). Compared with each corresponding model group, the FSH content decreased (P < 0.01) and LH increased in the GS medication group; the T content increased, E2 and LH decreased (P < 0.05, P < 0.01) in the PD medication group; the T content decreased (P < 0.01), GnRH, E2, FSH, and LH increased (P < 0. 05, P < 0.01) in the GSPD medication group.

CONCLUSIONSThere exist different degrees of abnormal function of the gonad axis in the GS, PD, and GSPD models. CSD had certain regulatory effect on the 3 syndromes. Of them, it showed a more comprehensive role in improving the gonad function axis. Results of this experiment had provided the experimental evidence for higher correlation between CSD and GSPD syndrome.

Objective:To evaluate the clinical efficacy and safety of compound glycyrrhizin combined with tripterygium wilfordii polyglycosides for psoriasis.Methods:Literature search was conducted in CNKI, Wanfang, VIP databases, Sinomed, PubMed, the Cochrane Library and Embase with the deadline of September 28th, 2020. The randomly controlled trials of compound glycyrrhizin combined with tripterygium wilfordii polyglycosides in treating psoriasis was included. The publication bias and methodology quality of RCTs were evaluated according to the Cochrane 5.0.1 bias risk assessment method. The RevMan 5.3 software was used for meta analysis.Results:Ten studies with 961 patients were included, with the experimental group ( n=486) and the control group ( n=475). The results of meta-analysis showed that the total effective rate [ OR=3.16, 95% CI (2.00-4.99), P<0.001], the cure rate [ OR=2.56, 95% CI (1.94-3.61), P<0.001], the recurrence rate [ OR=0.15, 95% CI (0.04-0.60), P=0.007], the total incidence of adverse reactions [ OR=0.53, 95% CI (0.34-0.82), P=0.004], the incidence of abnormal liver function [ OR=0.17, 95% CI (0.06-0.47), P=0.001] in the experimental group were better than those in the control group. There was no significant difference on the incidence of adverse reactions of digestive tract ( P>0.05) or lower extremity or facial edema ( P>0.05) between both groups. Conclusions:Compound glycyrrhizin combined with tripterygium wilfordii polyglycosides is effective in the treatment of psoriasis than tripterygium wilfordii polyglycosides alone, and can reduce the recurrence rate and the incidence of adverse reactions. However, a large number of large samples and high-quality studies are still needed.

Objective:To analyze the mean levels of skeletal muscle mass and strength in elderly patients with type 2 diabetes mellitus(T2DM), and to investigate the effects of chronic inflammatory factors and oxidative stress on them.Methods:A cross-sectional study was conducted on 120 patients with T2DM aged over 60 years and 126 elderly patients without diabetes(the control group). Skeletal muscle mass, strength and serum levels of chronic inflammatory factors interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and 8-hydroxy-2′-deoxyguanosine(8-OHdG)were determined, and their effects on skeletal muscle mass and strength in elderly patients with T2DM were analyzed.Results:Compared with the control group, grip strength decreased in elderly patients with T2DM(25.03±7.85)kg vs.(29.52±7.73)kg( P<0.01), and skeletal muscle mass decreased(21.36±5.46)kg vs.(22.01±5.22)kg with no significant difference( P>0.05). Serum levels of 8-OHdG were higher in elderly patients with T2DM than in the control group(3.08±0.26)ng/L vs.(2.59±0.16)ng/L( P<0.01). Correlation and regression analysis results showed that 8-OHdG was an influencing factor for muscle strength in elderly patients with T2DM( R2=0.457)and that height and weight could be influencing factors for skeletal muscle mass in elderly patients with T2DM( R2=0.822). Conclusions:Skeletal muscle mass and strength decline in elderly T2DM patients, probably as a result of increased levels of oxidative stress.These findings may serve as evidence for sarcopenia intervention in elderly T2DM patients.
