Objectives To study the relationship between TCM syndromes and adiponectin (APN) level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis, and provide evidence for clinical diagnosis and treatment. Methods One hundred patients of hypertension complicated with carotid atherosclerosis were divided into phlegm syndrome group, stasis syndrome group, and intermingled phlegm and blood stasis syndrome group, and compared with 30 healthy people as control. Carotid atherosclerosis plaque was detected with GE LOGIQ500 color ultrasound system. ELISA was used to determine the serum APN. Results APN of the intermingled phlegm and blood stasis syndrome group was obviously lower than other groups, and there were obvious differences among them. There were more plaques in the intermingled phlegm and blood stasis syndrome group. A negative correlationship was showed between carotid artery intima media thickness (IMT) and APN of hypertension complicated with carotid atherosclerosis. Conclusion There is correlation between TCM syndrome and APN level, carotid atherosclerosis plaque of hypertension complicated with carotid atherosclerosis. The anomalous change of APN and plaque formation of the patients can be preliminarily estimated with the syndrome of TCM.

Objective To compare the immunoregulatory effects of Radix Millettia Speciosa (RM Speciosa) and Radix Millettia Championi (RM Championi)on immunosuppressed mice.Methods Kunming mice were randomly divided into normal control group,CTX model group,LMS positive group,RM Speciosa groups and RM Championi groups (20,10 and 5 g/kg).The mice were treated respectively with drug or NS once a day for consecutive 20 days.Mice in the other groups were injected intraperitoneally with CTX at days 8,10 and 12 to establish immunosuppressed mice model except the normal group.The changes of body weight,immune organ weight,white blood cell (WBC)number,carbon particle clearance capability of macrophages and delayed type hypersensitivity (DTH)of mice in all groups were determined and compared.Results Compared with that in CTX group,the WBC number was significantly increased (P<0.01 or P<0.05)and the degree of DTH (P<0.01) was enhanced at different doses in RM Speciosa groups and RM Championi groups.The activity of macrophages and the index of thymus and spleen were also improved in the treatment groups (P<0 .0 5 or P<0 .0 1 ).The index of thymus and the degree of DTH in RM Speciosa groups (20 and 10 g/kg)were slightly higher than those in the corresponding RM Championi groups (P<0.01 or P<0.05).For other indicators,RM Speciosa groups did not significantly differ from RM Championi groups (P>0.05).Conclusion Both RM Speciosa and RM Championi can improve the immune function of CTX-induced immunosuppressed mice,and RM Speciosa is slightly superior to RM Championi in improving specific cellular immunity.

OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).
METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.
RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.
CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

Chinese Journal of Immunology 2018;34(4):553-557,563
Objective:To investigate the effect of miR-34a targeting PAX6 on JAK/STAT signaling pathway on invasion and metastasis of retinoblastoma.Methods:The expression of PAX6 in retinoblastoma tissues was detected by immunohistochemistry.The expression of miR-34a in retinoblastoma cell line was detected by PCR.The effect of miR-34a on the expression of PAX6 was examined by the dual luciferase gene system.Transwell invasion assay and scratch test was used to detect the ability of invasion and migration in the retinoblastoma cell line Rb44 after overexpression miR-34a.Western blot was used to detect the protein expression of JAK/STAT signal pathway after overexpression miR-34a.Results:The expression of PAX6 was significantly higher in retinoblastoma tissues than that in normal tissues.The miR-34a was lower in retinoblastoma tissues than that in normal tissues.Western blot analysis showed the lowest level of PAX6 in Rb44 retinoblastoma.The dual luciferase reporter gene system showed that miR-34a could directly regulate the transcriptional activity of PAX6.The ability of invasion and migration was inhibited after overexpression miR-34a.The expression level of PAX6 was down-regulated and the expression of JAK1/STAT3 protein were down-regulated after overexpression the miR-34a.Conclusion:miR-34a targets the expression of PAX6 and regulates the invasion and migration of retinoblastoma cells by JAK1/STAT3 signal pathway.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.
