BACKGROUND:The Wnt/β-catenin signaling pathway is one of the most important signaling pathways in stem cel regulation, which is involved in regulation of cel proliferation and differentiation. OBJECTIVE:To investigate the expression of Wnt/β-catenin main signaling molecule in inflammatory bowel tissues treated with bone marrow mesenchymal stem cel transplantation. METHODS:2,4,6-Trinitrobenzene sulfonic acid was used for establishing inflammatory bowel diseases rat models. Bone marrow mesenchymal stem cels labeled with green fluorescent protein were transplanted into rat modelsviatail vein. Normal saline was injected as control. The expression of Wnt/β-catenin signaling molecule was detected in the large intestine tissue of inflammatory bowel disease rat models by quantitative RT-PCR at 14 and 28 days after transplantation. RESULTS AND CONCLUSION:Real-time quantitative PCR results showed that the expression of Wnt3a andβ-catenin in the inflammatory bowel tissue increased significantly (P < 0.05), while no difference in the expression of c-myc (P > 0.05). The expressions of Wnt3a, β-catenin and c-myc in the transplantation group were significantly lower than those in the control group after transplantation (P <0.05). These findings indicate that the Wnt/β-catenin signaling pathway plays important roles in inflammatory bowel disease and repair after bone marrow mesenchymal stem cel transplantation, while this pathway may promote stem cels differentiating into intestinal epithelium, promote recovery from inflammatory bowel disease, repair inflammatory area, and restore intestinal tissue homeostasis.

Serum homocysteine may play an important role in renal injury and further affect the occurrence and development of hypertension by impairing the function of platelet , coagulation and fibrinolysis system .

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

ObjectiveTo determine the characteristics and influencing factors of hepatitis C virus （HCV） co-infection among HIV concordant couples in Dehong Prefecture. MethodsUsing the data of newly reported HIV concordant couples in Dehong Prefecture from 2016 to 2019， we collected the demographic characteristics， exposure history， and HCV infection to determine the characteristics of HCV co-infection among HIV concordant couples. ResultsAmong the 160 HIV concordant couples included in the study， 46 （28.8%） males and 14 （8.8%） females were co-infected with HCV. The prevalence of HIV-HCV co-infection was higher among the male spouses who were diagnosed less than 40， Jingpo ethnic， Burmese， illiteracy， farmers， and intravenous drug users. In contrast， the prevalence of HIV-HCV co-infection was higher among the female spouses who were diagnosed less than 40， Jingpo ethnic， and Burmese. Logistic regression analysis among male spouses showed that the Jingpo ethnic and intravenous drug users had higher risk of HCV co-infection. ConclusionHIV concordant couples in Dehong Prefecture have high prevalence of HIV-HCV co-infection. Effective intervention strategies should be developed based on ethnic-specific factors and exposure characteristics among male and female spouses of HIV concordant couples.
