ABSTRACT
Objective To investigate the effects of Qingzao Jiufei Tang(QJD)and its decomposing agent on the levels of TNF-α,INF-γ levels of TNF-α of Qingo, P1 and AQP5 in lung tissue of mice infected with Mycoplasma pneu-moniae(MP),and to clarify its molecular anti-infective mechanism. Methods One hundred-forty-four SPF grade BABL/c mice were randomly divided into the normal group(group A),model group(group B),QJD group(group C),QJD de-composition agent I group(group D)、QJD decomposition group II Group(group E)and azithromycin group(group F), with 24 rats in each group. Besides the group A,the other 5 groups of mice were treated with MP infection. After the mod-eling,the mice were given corresponding drugs by gastric gavage,and samples were obtained on the days 3,7,10,14 af-ter the model was established. The lung tissue sections were examined by histopathology, and the degrees of inflammation in lung tissues in the mice were evaluated,and the lung index and the ratio of dry and wet lung weight ratio in the mice were calculated. The levels of MPN372 and P1 genes were determined by qPCR assay. The serum TNF-α and INF-γ levels in the mice were assessed by enzyme linked immunosorbent assay(ELISA). The expression of AQP5 protein was detected by Westernblot. Results After MP infection, the pathological examination revealed thickening of alveolar septum and bronchioles,and extensive inflammatory cell infiltration in the lung tissues. The lung index was increased and the ratio of dry and wet lung weight(P<0.05). TNF- α and INF-γ cedd and was increased, and reached the peak on the seventh day. The expression of AQP5 protein showed a downward tendency,and began to gradually increase on the 14th day. Com-pared with the group B,the expression levels of MPN372,P1 and TNF-α in the group D were down-regulated,and the ex-pression levels of INF-γ levein the group E were up-regulated from the 7th day. Conclusions QJD can control pulmonary inflammation in mice after MP infection. The decrease of production of MP toxin MPN372 and the expression of adhesion protein P1,the up-regulation of expression of INF-γ and AQP5 proteins,and down-regulation of TNF-α expression are one of the mechanisms of its action.
ABSTRACT
Objective To observe the effect of Qingzao-Jiufei decoction and its composition on the levels of IL-10,TNF-α, CD4+cells, CD8+T cells and the change of CD4+/CD8+ratio in the serum to explore the mechanism of anti-MP infection. Methods The 144 SPF grade BALB/c mice were randomly divided into the normal group, the model, the whole decoction group, the composition Ⅰ group, the composition Ⅱgroup with the method of random digital table, and the azithromycin group and every group had 24 mice. The following five groups were treated with infection of MP model. After successful modeling, the rats in the whole decoction group were treated by gavage with 1 g/ml Qingzao-Jiufei decoction. The rats in the composition Ⅰ group were treated by gavage with 0.61 g/ml composition Ⅰ decoction. The rats in the composition Ⅱ group were treated by gavage with 0.39 g/ml composition Ⅱ decoction. And the three groups were administered for 14 days. The rats in the azithromycin group were treated by gavage with azithromycin suspension once a day. After three days, the drug was stopped. Each group was infected on 3,7,10,14 day. Then mice were sacrificed, with the method of taking the eye of the mice to take blood. The level of IL-10, TNF-α in the mice blood with the method of ELISA were detected. The level of CD4+, CD8+T in the rinsing solution of mice spleen with the method of FCM and the CD4+/CD8+ ratio were detected. Results Compared with the model group, the expressions of CD4+T cells (24.50 ± 1.41 vs. 22.08 ± 1.99) and IL-10 (18.15 ± 0.36 vs. 8.75 ± 0.16) in the whole decoction group significantly increased. The expressions of CD8+T cells (7.29 ± 1.23 vs. 9.13 ± 1.14) and TNF-α (28.32 ± 1.90 vs. 37.97 ± 1.71) significantly decreased (P<0.05), and the level of CD4+/CD8+ratio increased. In the composition Ⅰ group, the expressions of CD8+T cells (7.50 ± 1.45 vs. 9.13 ± 1.14) and TNF-α(33.48 ± 1.08 vs. 37.97 ± 1.71) significantly decreased (P<0.05). In the composition Ⅱ group, the expressions of CD4+T cells (23.63 ± 1.10 vs. 22.08 ± 1.99) and IL-10 (17.82 ± 0.63 vs. 8.75 ± 0.16) significantly increased (P<0.05). Conclusions The mechanism of Qingzao-Jiufei decoction on anti-MP infection may be related to the regulation of the cellular immune.
ABSTRACT
This study was aimed to evaluate the clinical effect and safety of Qing-Fei Tong-Luo (QFTL) ointment for treating children with pneumonia.Randomized controlled trial (RCT) was conducted among 460 cases of children with pneumonia.The observation group was given QFTL ointment combined with basic treatment.And the control group was only treated by basic treatment.Evaluation was given on the total clinical efficacy,disappeared time of fever,cough,expectoration,shortness of breath,and medication safety.The incidence of respiratory diseases was followed up on the 30th days after drug withdrawal.The results showed that in the aspect of clinical efficacy between two groups,the cure rate of the observation group was 98.26％,and that of the control group was 93.89％,with statistic significance (P ＜ 0.05).The cure rate of the observation group was better than that of the control group.There was statistical difference on expectoration disappeared time (P ＜ 0.05).There was no statistical difference on disappeared time of fever,cough and shortness of breath (P ＞ 0.05).There was statistical difference on the incidence of respiratory diseases on the 30th days followed-up after drug withdrawal (P ＜ 0.05).There was no statistical difference on the incidence of upper respiratory tract infection,pneumonia and asthma (P ＞ 0.05).No adverse reactions occurred in the observation group.It was concluded that QFTL ointment combined with basic therapy on the treatment of pneumonia in children was significantly better than the control group in the aspect of clinical efficacy,expectoration disappeared time and the incidence of bronchitis.It is safe and effective.The prognosis is good and worthy of promotion in the clinical practice.

ABSTRACT
Objective To investigate the feasibility and clinical effect of immediate ureterovesical reimplantation after ureteral rupture during laparoscopic hysterectomy. Methods From August 2010 to December 2015, 5 cases of ureteral rupture during the operation of laparoscopic hysterectomy were treated with immediate ureterovesical reimplantation under laparoscopy. Results All operations were successfully performed without transversion to open surgery. No patients with urinary leakage occurred. The mean follow-up were 21 months (range 3-60 months) . No cases with ureteral stricture were observed. Slight urine reflux was found in two patients, of whom obvious hydronephrosis and renal damage were not found. Conclusion Immediate ureterovesical reimplantation under laparoscopy is a feasible, safe and minimal invasive method for treatment of ureteral ruputure during laparoscopic hysterectomy.
ABSTRACT
Objecitve To study the inhibitory effect of pioglitazone on inflammation factors in patients with bladder cancer. Methods A total of 100 consecutives diagnosed as bladder cancer from Februray 2013 to Februray 2014 were individed ran-domly into experiment and control groups and each of 50 cases.All patients received the appropriate operation or chemother-apeutic regimens,and the patients in experiment group received pioglitazone (15 mg/d×12 weeks)at the same time.Then to compare expression differences of high-sensitive C reactive protein (hs-CRP),tumor necrosis factor alpha (TNF-alpha),in-terleukin (IL-6)and HOMA-IR,MCP-1,MIP-1 levels.Results The levels of hs-CRP,TNF-αand IL-6 in the two groups af-ter treatment were all lower (P 0.05).Conclusion Pioglitazone could improve clinical effect and prognosis by lowing inflam-mation factors including hs-CRP,TNF-α,IL-6,HOMA-IR,MCP-1 and MIP-1 in patients with bladder cancer.
ABSTRACT
Objective To investigate radiographic features of pneumocystis carinii pneumonia(PCP)or Kaposi sarcoma(KS),which were the most common complications of AIDS after renal transplantation.Methods Radiographic diagnosis and differential diagnosis of 2 cases with PCP and KS comfirmed by pathology were discussed by analysing the chest X-ray findings combined with revieuw of reference literature.Results The two cases with anti-HIV antibody all had mediasinal lymphopathy.In the case of KS,the omental tuber or tubercle shadows and pleural effusion were found on both pulmonary fields.Conclusion No characteristic chest radiographic meanifestations in AIDS,the definitive diagnosis depends on clinical laboratory examination and pathological examination.
