ObjectiveTo investigate the application value of Qingre Huashi Sanjie enema prescription in the treatment of the patients with sequelae of pelvic inflammatory disease (syndrome of combined dampness,heat,and stasis) and the effects of this prescription on inflammatory mediators and T lymphocyte subsets. MethodThe patients with sequelae of pelvic inflammatory disease (syndrome of combined dampness,heat,and stasis) treated from May 2022 to August 2023 were included in this study and randomized into two groups (79 cases). The control group was treated with conventional Western medicine,and the observation group was treated with Qingre Huashi Sanjie enema prescription on the basis of the therapy in the control group. Both groups were treated for 12 weeks. The serum levels of monocyte chemoattractant protein-1 (MCP-1),transforming growth factor-β1 (TGF-β1),and interleukin-6 (IL-6) were measured by enzyme linked immunoserbent assay (ELISA) before and after treatment in both groups. The erythrocyte sedimentation rate (ESR) and fibrinogen (FIB) were measured by an automatic blood rheology analyzer before and after treatment in both groups. The serum levels of CD4+,CD4+/CD8+ before and after treatment in both groups were measured by flow cytometry. The traditional Chinese medicine (TCM) symptom score and the 36-item short form survey (SF-36) score were assessed before and after treatment. The uterine artery resistance index (RI),uterine artery pulsatility index (PI),and uterine artery peak systolic velocity (PSV) were measured by Doppler before and after treatment. The clinical efficacy and the occurrence of adverse reactions were compared between the two groups. ResultAfter treatment,the levels of MCP-1,TGF-β1,IL-6,ESR,and FIB decreased in both groups (P<0.01),and the decreases were larger in the observation group than in the control group (P<0.05,P<0.01). After treatment,the serum levels of CD4+ and CD4+/CD8+ elevated in both groups (P<0.01) and the observation group had higher levels of CD4+ and CD4+/CD8+ than the control group (P<0.05,P<0.01). The treatment in both groups decreased the TCM symptom score and TCM sign score and increased the SF-36 score (P<0.01),and the changes were more significant in the observation group than in the control group (P<0.05,P<0.01). In addition,the treatment lowered RI and PI and elevated PSV (P<0.01),and the changes in these indicators were more significant in the observation group than in the control group (P<0.01). The total response rate in the observation group was 93.67% (74/79),which was higher than that (79.75%,63/79) in the control group (χ2=6.645,P<0.05). There was no significant difference in the occurrence of adverse reactions between the two groups. ConclusionFor the patients with sequelae of pelvic inflammatory disease (syndrome of combined dampness,heat,and stasis),Qingre Huashi Sanjie enema prescription can reduce inflammation,attenuate hypercoagulability,improve hemodynamics,and regulate the immune function,demonstrating a definite therapeutic effect.

Objective To analyze the dynamic changes and the influencing factors of T lymphocyte subsets in recipients with stable graft status within 1 year after lung transplantation. Methods Clinical data of 41 recipients with stable graft status after allogeneic lung transplantation were analyzed. The absolute value and ratio of T lymphocyte subsets in peripheral blood from recipients were measured by flow cytometry before operation, 2 weeks and each month (within 1 year) after operation, respectively. The effects of age, gender, body mass index (BMI), surgical method, incidence of primary graft dysfunction (PGD) after operation, and primary disease upon the absolute values of T lymphocytes were evaluated. Results Within 1 year after lung transplantation, the absolute values of CD3+, CD3+CD4+, CD3+CD8+T lymphocytes and CD4+/CD8+ ratio were changed over time (all P < 0.001). Compared with preoperative values, there was no statistical significance in the absolute values of CD3+ and CD3+CD4+T lymphocytes at 12 months after operation (P=0.659, 0.109), whereas the absolute value of CD3+CD8+T lymphocytes was increased (P=0.02) and the CD4+/CD8+ ratio was decreased (P < 0.001). Age, gender, BMI, surgical method and incidence of PGD after operation exerted no significant effect on the dynamic changes of absolute values of CD3+CD4+ and CD3+CD8+T lymphocytes (all P > 0.05). Primary disease before lung transplantation exerted no effect on the changes of CD3+CD4+T lymphocytes, whereas the postoperative absolute value of CD3+CD8+T lymphocytes was higher in recipients with infectious lung diseases (P < 0.05). Conclusions The absolute values of CD3+, CD3+CD4+, CD3+CD8+T lymphocytes in recipients with stable graft status after lung transplantation are relatively low in the early stage after lung transplantation, then gradually restore, and stabilize at 6 months after operation. Dynamic changes are not associated with age, gender, BMI, surgical method and incidence of PGD after operation of recipients.

OBJECTIVE: To investigate the relationship between pathogenesis of PBB and the T cell subsets disorders and to evaluate the clinical significance of immunomodulatory therapy to the prognosis of PBB and the prevention of recurrent PBB. METHODS: A total of 127 cases of PBB children treated in the Fourth Hospital of Baotou City from May2015 to May 2018 were selected. Blood samples were collected before treatment,and the levels of CD4,CD8 cells and CD4/CD8 in peripheral blood T cell subsets were detected by flow cytometry. All children with PBB(PBB group)were given oral amoxicillin and clavulanate potassium for 2 to 4 weeks. The subjects were divided into Huaiqihuang group(n=66)and non-Huaiqihuang group(n=66). The Huaiqihuang group was given Huaiqihuang granules based on the anti-infective treatment. In addition,healthy children were enrolled as control group(n=39). T cell subsets of the two groups were reexamined 3 months after treatment. By analyzing the cough symptom scores of all children after 2 weeks,4 weeks and 12 weeks of treatment,the rate of cure and improvement and the recurrence rate after 1 year were evaluated.SPSS16.0 software was used for data processing,and the difference was significant if P0.05). In 2 weeks after treatment,the cough symptom scores of the PBB group began to decrease,and the non-Huaiqihuang group decreased more significantly,with statistically significant difference(P0.05). Follow-up showed that the recurrence rate of Huaiqihuang group was lower than that of non-Huaiqihuang group in 1 year after the end of treatment,and the difference between the two groups was statistically significant(P<0.01). CONCLUSION: Children with PBB have T cell subsets disorder,and the treatment of anti-infection combined with Huaiqihuang granules for at least 4 weeks has a positive effect on PBB prognosis and recurrence prevention.

Objective To investigate the influence of coix seed triglyceride combined with transcatheter arterial chemoembolization (TACE) therapy on AFP, CD4﹢CD25﹢regulatory T (Treg) cells and cellular immune function in patients with advanced primary hepatocellular carcinoma (HCC). Methods A total of 50 patients with inoperable HCC, whose imaging examination showed no distant metastasis, were divided into the study group (n=25) and the control group (n=25). Coix seed triglyceride together with TACE was employed for the patients of the study group, while only TACE was adopted for the patients of the control group. For the patients of the study group, transcatheter hepatic artery infusion of 100 ml coix seed triglyceride was carried out during the performance of TACE, and postoperative intravenous drip of coix seed triglyceride (200 ml/d) was used for 5 days. The peripheral blood samples were collected one week before and one month after the treatment to detect the changes of AFP and T lymphocyte subsets (CD3﹢, CD4﹢, CD8﹢,CD4﹢/CD8﹢ and Treg) levels. One month after the treatment, enhanced CT, MRI or PET-CT was performed to evaluate the necrosis degree of the tumor. Results After the treatment, AFP levels was decreased in both groups, when compared the preoperative data the differences were statistically significant (P0.05). In the study group, the percentage of Treg cells decreased from preoperative (8.27±6.65)%to postoperative (4.22± 1.59)%, the difference was statistically significant (P0.05). Conclusion In treating advanced primary HCC, coix seed triglyceride combined with TACE can reduce the percentage of Treg cells, thus, influence the patient’s cellular immune status and possibly decrease the recurrence rate of HCC after TACE therapy.
