Abstract: Objective　To explore the effect of Yiaikang on the expression of sterile alpha motif and histidine-aspartic acid domain-containing protein 1(SAMHD1), a host restriction factor, and interferon levels in peripheral blood of HIV-infected patients with lung-spleen Qi deficiency syndrome. This aims to provide insights into the mechanism of YiaiKang in the treatment of AIDS. Methods According to the diagnostic criteria of Western medicine for AIDS and traditional Chinese medicine for lung-spleen Qi deficiency syndrome, 22 cases of HIV patients with lung and spleen Qi deficiency syndrome were enrolled in the study from the First Affiliated Hospital of Henan University of TCM between September 2020 and May 2021, and 20 healthy people in the area were taken as control. The patients with lung and spleen Qi deficiency syndrome were treated with Yiaikang for 6 months. T lymphocyte subpopulation changes and expression level of SAMHD1 protein in T cells were detected by flow cytometry. SAMHD1 mRNA expression in peripheral blood mononuclear cells (PBMCs) was detected by fluorescence quantitative PCR. The levels of IFN-α, IFN-β, IFN-γ, and IL-2 in plasma were detected by enzyme-linked immunosorbent assay (ELISA). The changes of SAMHD1 and interferon in peripheral blood of HIV patients with lung and spleen Qi deficiency syndrome were analyzed to explore the intervention effect of Yiaikang. Results Compared with healthy people, HIV patients with lung and spleen Qi deficiency syndrome exhibited a reduction in the CD4 + T lymphocyte count and CD4/CD8 ratio (Z=-3.526, P<0.001; Z=-0.881, P<0.001). There was an increase in the expression of SAMHD1 protein in T lymphocytes (SAMHD1 MFI/CD4: Z=-3.425, P=0.001; SAMHD1 MFI/CD8: Z=-2.153, P=0.031) and an increase in the expression of SAMHD1 gene in PBMCs (Z=-3.828, P<0.001). Yiaikang treatment significantly increased the CD4 + T cell count and CD4/CD8 ratio (Z=-2.711, P=0.007; Z=-2.062, P=0.039), decreased the expression of SAMHD1 mRNA (Z=-2.581, P=0.010), and decreased the levels of IFN-α and IFN-γ (Z=-1.985, P=0.047; Z=-2.744, P=0.006). Conclusions Patients with lung-spleen Qi deficiency syndrome have reduced numbers of CD4 + T cells and CD4/CD8 ration, with increased expression of SAMHD1 and interferon factors. Yiaikang treatment can increase the number of CD4 + T cells and CD4/CD8 ratio and reduce the expression of SAMHD1 and interferon factor, thereby improving the immune imbalance caused by HIV infection.

Objective To study clinical value and significance of thyroid receptor stimulating antibody (TSAb) and thyroid stimulating-blocking antibody (TSBAb) on diagnosis and treatment for children with Graves’disease (GD) and Hashimoto’s thyroiditis (HT). Methods Eighty-eight children with autoimmune thyroid disease (AITD) and treatment time less six months were divided into GD group (n=55) and HT group (n=33). Thirty-eight healthy children were used as control (Normal group). Human serum TSAb ELISA kit and human TSBAb ELISA kit were used to detect the serum TSAb and serum TSBAb in three groups. The serum levels of TSAb and TSBAb were compared between three groups. The correla? tion between TSAb and TSBAb, TSAb/TSBAb and free triiodothyronine three (FT3), free thyroxine (FT4), ultra sensitive thy?roid stimulating hormone (TSH) were analyzed. Results The serum level of TSAb was significantly higher in GD group than that of HT group and Normal group (P<0.05). The serum level of TSBAb was significantly higher in HT group than that of Normal group (P<0.05). There was no significant correlation between serum TSAb and serum TSBAb (P>0.05). There were no significant correlation between serum TSAb, TSBAb and FT3, FT4, TSH (P>0.05). Conclusion TSAb and TSBAb are related to the pathogenesis of GD and HT in children. TSAb and TSBAb have an important clinical value in the diagnosis and treatment for children with GD and HT.

Objective To analyze the effects of the mumps virus on testicular function and evaluate the value of blood testosterone in acute orchitis condition and prognosis by observing the testosterone levels of peripheral blood in the mumps orchitis patients.Methods Thirty patients with acute mumps orchitis (mumps orchitis group)and 28 patients with mumps only without any major complications (mumps group)were enrolled in the study.At the same time,we selected 20 healthy males in our hospital as healthy controls.All cases were treated by ribavirin (10mg/kg). The testosterone was tested by chemiluminescence method,in 0,7,14 days respectively.The variance analysis and LSD -t test were used to compare differences of blood testosterone in each group,and Pearson method was used to analyze the correlation of blood testosterone and testicular swelling day times,blood amylase,level of neutrophils,IL -6 and CRP.Results The testosterone of acute orchitis [(1.51 ±0.26)ng/mL]was lower than mumps group and healthy controls.The difference was significant(F =99.36,P <0.01).The level of blood testosterone was significantly increased in the treatment for 14 days (t =13.03,P <0.01),and there was no significant difference compared with healthy controls (t =1.23,P =1.23).Pearson correlation analysis found that blood testosterone levels were negatively correlated with the days of testicular swelling,the levels of IL -6 and CRP(r =0.678,P <0.01 and r =0.528,P =0.000;r =0.442,P =0.000).Conclusion This study showed that MuV infection inhibited testosterone synthesis in Leydig cells.In other words,the level of blood testosterone is related to the severity of the orchitis,which can be widely used in clinical.

BACKGROUND: The study of tissue-engineered cartilage with predetermined shaping and regeneration has provided novel ideas and techniques for repair of laryngeal cartilage erosion; however, due to the special natures of the morphology, location and function of laryngeal cartilage, tissue engineering research has not, to date, exhibited its ful advantages in the reconstruction of laryngeal cartilage. OBJECTIVE:To explore the feasibility of building tissue-engineered larynx-shaped cartilage using poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) as a scaffold filed and encapsulated with pedicled myofascial flaps. METHODS:Porous PHBHH was prepared and formed into a holow like larynx-shape, and the cel PHBHH composites were cultured for 1 weekin vitro prior to implantationin vivo. The cel-PHBHH composite was filed and encapsulated with myofascial flaps with the pedicle forin situ implantation in nine rabbits as experimental group. PHBHH scaffold with no chondrocytes was implanted alone in three rabbits as control group. Cartilage regeneration was assessed at 6, 12 and 18 weeks after surgery through morphological observation, histological and immunohistochemical detection. RESULTS AND CONCLUSION: In the experimental group, the shape and porosity (> 90%) of the material were ideal, the cels exhibited good adhesion with the material and the blood supply within the myofascial flap with pedicle was rich for effective filing and encapsulation of the cel PHBHH composite. Tissue-engineered laryngeal cartilage with the holow, semi-trumpet shape was idealy formed at 6 weeks after the surgery. Further maturation of the cartilage was observed at 12 and 18 weeks after the surgery. However, there was no cartilage tissue in the control group. This study shows that PHBHH is a suitable material for the formation of a holow, semi-trumpet shape with good celular compatibility. Myofascial flap filing and encapsulating can be used to build tissue-engineered laryngeal cartilage with a holow, semi-trumpet shape.

I. Under scanning electron microscope, the vascular network of the cutaneous, subcutaneous, and deep fascia in planta can be divided into five layers according totheir vascular morphological characteristics. They are as following: the papillary layer, the subpapillary layer, the deep dermal layer, the subcutaneous layer, and the deep fascia layer. 2. The papillary layer is the most superficial one, it is easy to recognize that there are five types of capillary network: the single loop, the multiple loop, the tower-like type, the finger-like type, and irregular type. 3. The network in the subpapillary layer is polygon-like, parallel to the surface of skin. 4. In the deep dermal layer, there are many vascular balls in the vascular trunks. 5. The subcutaneous layer: The vascular networks are limited by fat lobules. 6. The vascular-trunks run across each other and anastomose each other in deep fascia layer.

Objective To study the influence on primipara's second stage of labor with the methods of Changqiang-pressing and Vaginal-pressing. Methods 180 primipara in the second stage of labor were randomly divided into 3 groups of 60 each, in which Changqiang-pressing, Vaginal-pressing and general guidance (the control group) were used respectively. The duration of uterine contraction and second stage of labor, vaginal bleeding amount in 2 hours after delivery, mode of delivery, perineal injury and birth case would be evaluated. Results The results in both Changqiang-pressing group and Vaginal-pressing group were statistically significant when compared with the control group, but there was no significant difference between Changqiang-pressing group and Vaginal-pressing group. Conclusions Using Changqiang-pressing and Vaginal-pressing can promote the progress of the second stage of labor for primipara, reduce the rate of cesarean section and neonatal asphyxia, and improve the quality of obstetric department.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Purpose:To study the roles of cyclin D1 and cyclin E in non small cell lung cancer(NSCLC) and the relationship between cyclin D1 and cyclin E.Methods:The expression of cyclin D1 and cyclin E in 87 NSCLC were studied immunohistochemically, PCNA was detected immunohistochemically to estimate the proliferative index(PI), the relationship between cyclin D1, cyclin E, PI, clinicopathological and prognostic factors were analysed.Results:Of the 87 NSCLC, 44 8%(39/87) were positive for cyclin D1 and 48.3%(42/87) for cyclin E, the PI of the cyclin D1 positive group was significantly higher than the cyclin D1 negative group( P 〈0.05).Significant differences were shown in the diameter of tumor, lymph node metastasis rate and survival rate between the positive and negative group of cyclin D1( P 〈0.01,0.05,0.01), and there were significant differences in lymph node metastasis, stages and survival rate between the positive and negative group of cyclin E( P 〈0.05,0.05,0.01). The expression of cyclin E in the cyclin D1 positive group was significantly higher than that of the cyclin D1 negative group( P 〈0.05), and the PI, diameter of tumor, lymph node metastasis rate in the coexpression group of cyclin D1 and cyclin E were significantly higher than that of the non coexpression group( P 〈0.05), while the coexpression group had significantly lower survival rate than that of the non coexpression group( P 〈0.05).Conclusions:Cyclin D1 and cyclin E are involved in NSCLC, but their effects are different: cyclin D1 is an important factor in the regulation of proliferation, cyclin E is related to the progression of NSCLC, cyclin D1 can promote the expression of cyclin E, while cyclin E can perhaps intensify the effect of cyclin D1, thus there could exist synergism between cyclin D1 and cyclin E.
