Abstract: Objective To investigate the frequency of peripheral blood T cells among patients positive for both hepatitis B virus surface antigen (HBsAg) and surface antibody (HBsAb). Methods Thirty six patients with co-existence of HBsAg and HBsAb diagnosed were enrolled as the experimental group, who were admitted by Shanghai tenth people's hospital and Wuxi 9th people's hospital from 2014 to 2020. while 40 patients tested positive for HBsAg and negative for HBsAb served as controls, who were admitted by Wuxi 9th people's hospital. Flow cytometry was used to detect and compare the proportions of peripheral blood CD3+, CD4+ and CD8+ T cells between the experimental and control groups. In addition, the associations of serum HBsAb level with peripheral blood T cell proportions, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were examined among chronic hepatitis B patients with co-existence of HBsAg and HBsAb using Pearson correlation analysis. Results The median age, gender distribution, mean ALT and AST concentrations, proportion of HBV DNA viral load>103 copies/mL, seroprevalence of HBV E antigen (HBeAg), seroprevalence of HBV E antibody (HBeAb), seroprevalence of HBV core antibody (HBcAb) were comparable between the experimental and control groups, and there were no significant difference in them (P>0.05). There were no significant difference between the experimental and control groups in terms of CD3+ T cell proportion [(71.83±1.50)% vs (72.75±1.47)%; t=0.66, P>0.05], CD4+ T cell proportion [(36.81±1.53)% vs (39.88±1.57)%; t=1.43, P>0.05] and CD8+ T cell proportion [(33.17±2.04)% vs (32.40±1.75)%; t=0.77, P>0.05]. Pearson correlation analysis revealed that the serum HBsAb level did not significantly correlate with peripheral blood CD3+ (r=0.026, P=0.65), CD4+ (r=‒0.08, P=0.16) and CD8+ T cell proportions (r=0.09, P=0.24), CD4+/CD8+ T proportion (r=‒0.005, P=0.35), serum ALT (r=0.04, P=0.56) and AST levels (r=0.002, P=0.69) among chronic hepatitis B patients with co-existence of HBsAg and HBsAb. Conclusions There are no significant differences between HBsAg+/HBsAb+ and HBsAg+/HBsAb- CHB patients in terms of peripheral blood CD3+, CD4+ and CD8+ T cell proportions.

Objective To evaluate the impact of PET/CT on the clinical therapeutical strategy of patients with non-small cell lung cancer (NSCLC). Methods Sixty patients with histologically confirmed NSCLC supposed to accept radical radiotherapy or surgical operation were firsthy divided into group A (stage Ⅰ-Ⅱ) and group B (stage Ⅲ) according to CT findings, and the individualized treatment strategy was designed, then restage and compare with different stage and management with initial treatment strategy by PET/CT scanning. Results ①PET/CT scanning restaged the TNM stage in 53.33% (32/60) patients, including 3 of T stage, 23 of N stage and 9 of M stage. Changes of stage occurred in 65.85% (27/41) patients with adenocarcinoma and in 26.32% (5/19) with squamous carcinoma (P<0.05), while in 34.29 (12/35) with central and 57.14% (20/35) with peripheral NSCLCs (P<0.05). ②PET/CT scanning resulted in alteration of the managements of NSCLC patients. The management changed from radical into palliative strategy with PET/CT information in 9 (15.00%) patients. In 25 patients who were supposed to accept surgical operation, the treatment changed to radical radiotherapy in 8 (8/25, 32.00%) and to palliative radiotherapy in 5 (20.00%) patients. In 35 patients who were supposed to accept radiotherapy, surgical operation or palliative radiotherapy was finally chosen in 5.71% (2/35) and 11.43% (4/35) patients, respectively. Conclusion PET/CT images can make significant alteration to clinical stage and treatment plan in patients with NSCLC.

OBJECTIVETo explore the in vitro anti-tumor effect and mechanism of dendritic cell (DC) tumor vaccine induced by astragalus polysacharin (APS).
METHODSPeripheral blood mononuclear cells (PBMCs) isolated from human peripheral blood. DCs obtained from human peripheral blood were cultivated and added with culture solution for in vitro inducing them to immature DCs. On the 5th day of culture, 100 microg/mL (as the final concentration) APS was added to cells in the APS group. DCs were induced to mature in the cytokine groups by adding 20 ng/mL rhTNF-alpha (as the final concentration). Changes of morphology and phenotype of DCs were observed. Mature DCs were sensitized with tumor antigen SGC-7901 and co-cultured with allogeneic T cells. The proliferative function of T lymphocytes was detected by MTT assay. Levels of IL-12 and IFN-gamma in co-cultured supernatant were detected by ELISA. Cytotoxic lymphocytes (CTL) activated by DC were co-cultured with tumor cell SGC-7901. The specific killing capacity of CTL to target cells was detected by LDH release assay.
RESULTSThe morphological observation and phenotypic identification of APS induced DCs were in accordance with the characteristics of mature DCs. APS induced mature DCs could stimulate the proliferation of allogeneic T lymphocytes. The proliferation index of T cells increased with increased ratio of stimulator cells to effector cells (P < 0.05). Levels of IL-12 and IFN-gamma in co-culture supernatant significantly increased in a time-dependent manner (P < 0.05). CTL cells activated by sensitization of DCs could significantly kill tumor cells, and the killing effect increased along with increased effector-to-target ratio.
CONCLUSIONAPS could in vitro induce DCs to mature, promote its antigen-presenting capacity, effectively activate CTLs, and enhance anti-tumor function of the organism.

OBJECTIVETo study whether acupressure could relieve urinary retention after radical hysterectomy in cervical cancer patients.
METHODSA randomized controlled prospective double-blinded trial was carried out in 107 urinary retention patients undergoing grade III radical hysterectomy. They were assigned to Group A (positive acupoints, 40 cases), Group B (negative acupoints, 32 cases) , and Group C (with no acupoints, 35 cases). All patients received protective 115 000 potassium permanganate sitz bath, 15 - 20 min each time, 3 times per day. Patients in Group A received acupressure at positive points [liniao point and Qihai (RN6)] combined points by syndrome typing [Guanyuan (RN4) , Zhongji (RN3) , Shenshu (BL23) , Zusanli (ST36), Sanyinjiao (SP6), and Taixi (K13)]. Patients in Group B received negative acupressure at sham-acupoints (for adjusting gastrointestinal functions). Patients in Group C only received conventional sitz bath. All medication was performed 3 times per day, 7 days as one therapeutic course, 21 days in total. The residual urine volume was detected. The recovery time for bladder function was recorded. The average residual urine volume was also recorded at day 7, 14, and 21.
RESULTSCompared with Group B and C, the time for ureter retention was shortened for mild and severe CKD patients in Group A (P <0. 01). The residual urine volume was also lessened for mild and severe CKD patients in Group A at day 7, 14, and 21 (P <0.01).
CONCLUSIONCervical cancer patients could relieve urinary retention by self-acupressure after radical hysterectomy.

The study aims to develop a unified method to determine seven phenolic acids (neochlorogenic acid, chlorogenic acid, 4-caffeoylquinic acid, caffeic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C) contained in honeysuckle flower that is the monarch drug of all the eight Yinqiao Jiedu serial preparations using quantitative analysis of multi-components by single-marker (QAMS). Firstly, chlorogenic acid was used as a reference to get the average relative correction factors (RCFs) of the other phenolic acids in ratios to the reference; columns and instruments from different companies were used to validate the durability of the achieved RCFs in different levels of standard solutions; and honeysuckle flower extract was used as the reference substance to fix the positions of chromatographic peaks. Secondly, the contents of seven phenolic acids in eight different Yinqiao Jiedu serial preparations samples were calculated based on the RCFs durability. Finally, the quantitative results were compared between QAMS and the external standard (ES) method. The results have showed that the durability of the achieved RCFs is good (RSD during 0.80% - 2.56%), and there are no differences between the quantitative results of QAMS and ES (the relative average deviation < 0.93%). So it can be successfully used to the quantitative control of honeysuckle flower principally prescribed in Yinqiao Jiedu serial preparations.
