OBJECTIVE:To observe the efficacy and safety of moxifloxacin combined with Jiehe pill in the treatment of muilt drug-resistant tuberculosis(MDR-TB). METHODS:116 patients with MDR-TB were randomly divided into control group and ob-servation group. Control group was given Moxifloxacin hyohochloride tablet 0.4 g once a day,observation group was additionally given Jiehe pill 9 g,twice a day,and 2 groups were given rifapentine,albendazole isoniazid,amikacin,pasiniazide,pyrazin-amide,p-amino salicylic acid and other conventional treatment. The treatment course for both groups was 18 months. The clinical efficacy,and T cell subsets (CD3+,CD4+,CD4+/CD8+),interferon(INF)γ,interleukin(IL)4 levels before and after 6,12 and 18 months,and incidence of adverse reactions in 2 groups were recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,CD3+,CD4+,CD4/CD8 and INF-γ level in 2 groups were significantly higher than before and gradually increased by time,and observation group was high-er than control group;IL-4 level was significantly lower than before and graually decreased by time,and observation group was lower than control group,the differences were statistically significant(P<0.05). There was no significant difference in the inci-dence of adverse reactions(P>0.05). CONCLUSIONS:Based on the coventional treatment,moxifloxacin combined with Jiehe pill has better efficacy than moxifloxacin in the treatment of MDR-TB,with similar safety.

BACKGROUND:Caffeic acid phenethyl ester (CAPE) can inhibit lipid peroxidation after rat brain injury. However, the trend of 5-lipoxygenaseis (5-LOX) and cysteinyl leukotrienes (CysLTs) in model of Parkinson’s disease, and whether CAPE protects against rotenone-induced cel ular injuries by inhibiting the levels of 5-LOX and CysLTs stil need further research.
OBJECTIVE:To investigate the protective effect of CAPE on the rotenone-induced Parkinson-like injury, and to determine whether 5-LOX involved.
METHODS:(1) PC12 cel s in good-growth were col ected and divided into five groups cultured with different concentrations of rotenone (0, 0.01, 0.1, 1, 10μmol/L). 24 and 48 hours later, changes of cel ular morphology and activity were observed to single out the optimum concentration of rotenone;at 24 hours, the levels of 5-LOX and CysLTs were detected by western blotting and ELISA, respectively. (2) PC12 cel s were pretreated with different concentrations of CAPE (0, 0.01, 0.1, 1, 10 μmol/L) for 30 minutes, and 1 μmol/L rotenone was then added. The other cel s received no intervention as blank control group. Subsequently, the cel activity was detected, and the CysLTs production was detected by ELISA at 24 hours.
RESULTS AND CONCLUSION:(1) Rotenone (0.1-10μmol/L) could induce PC12 cel injury with overt morphological and cel activity changes at 24 hours, especial y the 1 μmol/L rotenone. (2) Rotenone also significantly increased the 5-LOX expression and CysLTs production in a concentration-dependant manner. (3) CAPE (1-10μmo/L) significantly attenuated rotenone-induced CysLTs production and cel viability reduction in a concentration-dependant manner. (4) These results suggest that CAPE protects against PC12 cel injuries in the model rat with Parkinson’s disease induced by rotenone involving 5-Lox.

Objective To evaluate the effects of small dose of antithymocyte globulin(ATG)and zenapax in the induction therapy for kidney transplant recipients.Methods A series of 150 cadaver-donor kidney transplant recipients were randomly divided to 3 groups,ie,small dose of ATG group(total dose,2.1 -3.0 mg/kg;n=72),zenapax group(50mg,on the first and 14th d after operation;n=15)and controls without induction therapy(n=63).Follow-up was 6 months.The rates of acute rejection,delayed graft func- tion(DGF)and pulmonary infection were statistically compared among the 3 groups.Results During a 6-month period,in ATG,zenapax and control groups,acute rejection episodes occurred in 4 cases(5.5%), 1(6.7%)and 10(15.9%),respectively;DGF occurred in 3(4.2%),0 and 8(12.7%),respectively;pul- monary infection occurred in 4(5.1%),1(6.7%)and 3(4.8%),respectively;leucocytopenia occurred in 3(4.2%),1(6.7%)and 5(7.9%),respectively;thrombocytopenia occurred in 2(2.8%),1(6.7%)and 5(7.9%),respectively.Conclusions In the early stage of kidney transplantation,small dose of ATG and zenapax can be the optimal choice for induction therapy.

20% increase in serum creatinine over the last 6 months or progression to the range of 176-308?mol/L.Patients underwent abrupt cessation of cyelosporine and sirolimus maintenance at 1-2 rag/day after administration of 4-6 mg as first loading dose.Concomitant immunosuppression remained unchanged during conversion.Results Targeted sirolimus level was 4-8 ng/mL.Serum creatinine was dropped from pre-conversion level of(242.15?73.04)?mol/L to(188.32?58.96)?mol/L and (173.36?58.08)?mol/L at 3rd and 6th month respectively(P

Dendritic cells (DCs) are uniquely well-equipped antigen (Ag)-presenting cells. This function of DCs, coupled with their remarkable plasticity, renders them attractive therapeutic targets for immune modulation. Recent data have demonstrated a promising role for pharmacologic treatment as a means of generating potent regulatory DCs. Herein, the evidence that the potential of regulatory DC the-rapy is considerable and that there are compelling reasons to evaluate it in the setting of organ transplantation in the near future are discussed in this paper.

Tumor cells leads to enhanced glucose uptake and the conversion of a larger fraction of pyruvate into lactate even under the circumstance of abundant oxygen. This phenomenon of aerobic glycolysis is known as the Warburg effect. Lactic acid, as an important tool for tumor cells to modify the tumor microenvironment, promotes the process of tumor invasion and metastasis, and contributes to tumor development by inducing and recruiting immunosuppression-related cells and molecules. Lactic acid could efflux out of the cancer cells via the monocarboxylate transporters to prevent intracellular acidification. Lactate can inhibit the cytolytic activity of T cells and natural killer (NK) cells, promoting the differentiation of tolerogenic interleukin 10 (IL-10)-producing dendritic cells. Moreover, the lactate-derived lactylation of histone lysine residues can promote macrophage polarization toward the M2-like phenotype, suppressing the immune response within the tumor microenvironment. In this review, we discuss the role of lactate as an immunosuppressor molecule that contributes to tumor evasion from the aspects of lactic acid metabolism and its effect on immune cells. And we explore the possibility of targeting potential targets in lactate metabolism for tumor treatment. At last, we proposed a tumor immunotherapy strategy by inhibiting the pathway of aerobic glycolysis and proteins associated with the production and transport of lactic acid.

AIM:To explore the inhibitive effects of cervical lymphadenectomy on kerstoplasy after alkaline burns.METHODS:The Wistar rats' corneas were transplanted into Sprague-Dawley(SD)rats' eyes which were randomly divided into 4 groups:group A(control group);group B,the cervicallymphadenectomy group;group C,corneal transplantation after the alkali burn injury;group D,cervical lymphadenectomy following group C.Out of 6 rats in each group,the cornea of one rat Was used for mawophage immunohistochemistry at day 14 after the transplantstion,and the remaining 5 rats were used for studying corneal immune rejection with a slit lamp.The time when allograft rejection occurred was recorded and mean survival times(MST)were compared among the groups.RESULTS:Compared with the MST of group A(10.40±1.14 days),the MST of group B(46.30±9.46 days)Was significantly longer(P＜0.05).MST of grafts between group C(7.00± 1.58 days)and group D(15.00±3.39 days)was also significant (P＜0.05).At 14th day after the transplantation,there was no CD68 immunoreactivity in the graft of group B,and CD68 proteins were expressed to some extent in the grafts of group A and D.However,in the graft of group C,the expression of proteins Was dramatically up-regulated.CONCLUSION:Cervical lymphadenectomy therapy has a significant effect in preventing corneal allograft rejection in normal and alkali burned oorneai beds.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Fifty-eight samples belonging to 7 species of Arisaematis Rhizoma and its adulterants were collected. The ITS2 locus was employed as a DNA barcode and amplified, sequenced and assembled for all of the collected samples. Then, ITS2 sequences have been annotated using HMM-based method. The intra- and inter-specific variations were calculated and NJ tree was constructed using MEGA 6.0 software. The results showed that inter-specific K2P distances were significantly larger than intra-specific distances for all of the three origin species of Arisaematis Rhizoma. Furthermore, three origin species, Arisaema amurense, A. erubescens and A. heterophyllum, can be respectively formed to be a single branch with high bootstrap values. It is concluded that ITS2 can be used to correctly identify Arisaematis Rhizoma from its adulterants and the application of ITS2 in the identification of traditional Chinese medicine has an important prospective.
