OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To evaluate the dose distribution in clinical target volume (CTV) and organs-at-risk (OARs) in three dimension therapy plans in patients with squamous cell carcinoma of tongue receiving postoperative intensity-modulated radiotherapy (IMRT) or conventional radiotherapy (CRT) by dosimetric study. Methods Thirty-five patients with squamous cell carcinoma of tongue were divided into CRT group(n=17) and IMRT group(n=18). All patients underwent head-and-neck immobilization with a thermoplastic mask and planning CT scan, and target volume and OARs were contoured. Dose calculation and plan optimization were performed. All three dimension plans passed quality assurance before treatment. The dosimetry of therapy plans with IMRT or CRT in target volume and OARs dose distribution was compared by dose-volume histogram (DVH), conformity index (CI) and homogeneous index (HI). Results There were significant differences in D95 (isodose line to cover 95 percent target volume), CI, HI, minimum dose and maximum dose in CTV of therapy plans between patients with IMRT and CRT(P < 0.01), and there was no significant difference in mean dose of CTV(P > 0.05). The radiation dose on salivary glands (both parotid glands and contralateral submandibular gland) in patients with IMRT was significantly lower than that in patients with CRT(P < 0.01). Conclusion Compared with dose distribution of CRT plans, there are more advantages in improving dose distribution at the target volume and sparing salivary glands in IMRT therapy plans in patients with squamous cell carcinoma of tongue.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Objective To identify a unique protein as a novel genetic marker for rapid molecular typing of Mycobacteriutn tuberculosis Beijing genotype strains by comparing the proteome of Beijing genotype strains with non-Beijing strains.Methods Fifty-six clinical isolates of Mycobacterium tuber- culosis were analyzed by spoligotyping to determine genotypes.The two-dimensional electrophoresis (2 DE)was used to compare the global protein patterns between Beijing genotype strains and non Bei jing strains.Differential expressed proteins were measured by matrix assisted laser desorption ioniza tion lime of flight mass spectrometry(MALDI-TOF-MS).The data obtained from peptide mass fingerprinting were compared in protein database.The genes encoding differential expressed proteins and their upstream were sequenced.Results Forty nine of the 56 isolates were Beijing genotype strains and 7 isolates were non-Beijing strains.A unique protein Rv0927c was identified,which is absent in Beijing genotype strains compared with 7 non Beijing strains and H37Rv.There were two characteristic mutations in Beijing genotype strains,a deletion of AGC at nucleotide position 421 of Rv0927c and a 127 G→A muta- tion in the upstream of Rv0927c.but not in non Beijing strains and H37Rv.Conclusion Characteris tic mutations of Rv0927c in Beijing genotype strains can be used as a novel genetic marker for rapid molecular typing of Mycobacteriuln tuberculosis Beijing genotype strains and non Beijing strains.

OBJECTIVETo observe the clinical effects of myopia in children treated with abdominal acupuncture.

METHODSNinety children with myopia were randomly divided into an abdominal acupuncture group (45 cases with 90 ill eyes) and an auricular point group(45 cases with 90 ill eyes). In the abdominal acupuncture group, Zhongwan (CV 12), Shangqu(KI 17), Xiawan(CV 10), Tianshu(ST 25), Qihai(CV 6), Guanyuan(CV 4) were treated with tapping method. The needles were not retained and down to the lower in accordance with the order from Zhongwan (CV 12) to Guanyuan(CV 4) for 5 min,and the erubescence skin without blood was proper. In the auricular point group, vaccaria seeds were pasted at gan(CO12), shen(CO10),pi(CO13), wei(CO4), yan(LO5), pingjianqian(TG2i), pingjianhou(ATli) and zhen(AT3); one ear was chosen every time and the other ear the second time with pressing of patient's own for 5 min every day. The treatment was given twice a week and 10 treatments were considered as one course in the two groups. The changes of the visual levels in visual chart before treatment, 20 min after the first treatment, after 5 weeks' and 3 months' treatment were compared between the two groups,and the clinicall efficacy was compared between the two groups as well.

RESULTS(1) The visual levels in visual chart were improved in the abdominal acupuncture group and auricular point group, and the effects 20 min after the first treatment, after 5 weeks' and 3 months' treatment in the abdominal acupuncture group were superior to those in the auricular point group(4. 78±0. 16 vs 4. 69±0. 22, P<0. 01; 4. 85±0. 16 vs 4. 79±0. 21, P<0. 05; 4. 89±0. 13 vs 4. 71±0. 25, P<0. 01). (2)The effective rates 20 min after the first treatment, after 5 weeks' and 3 months' treatment in the abdominal acupuncture group were better than those in the auricular point group[31. 4% (27/86) vs 0% (0/82). 81.4%(70/86) vs 60. 0%(49/82); 88. 4%(76/86) vs 51. 2%(42/82), all P<0. 01].

The known members of inhibitor of growth (ING) gene family are considered as candidate tumor suppressor genes. ING4, a novel member of ING family, is recently reported to regulate brain tumour angiogenesis through transcriptional repression of NF-?B-responsive genes, induce G2/M arrest by the increased p21 expression in a p53-dependent manner, suppress the loss of contact inhibition and represses activation of the hypoxia inducible factor, which plays an important role in the progression of tumorigenesis. However, seldom studies about ING4 inducing tumor cells apoptosis were reported.The C6 cells (mouse glioma cells) were infected respectively with the blank adenovirus carrying GFP (Ad) and the recombinated Ad-hING4-His, then RT-PCR assay was used to detect the transcriptions of hING4, as well Western-blotting assay was ued to detect the expressions of hING4. The effects of hING4 expression upon C6 cells were observed, and the growth curve was drawed and tumor control rates were calculated. The C6 cells, which were affected by blank Ad and Ad-hING4-His, were respectively observed by LSCM (laser scan confocal microscope) and transmission electron microscope (TEM), detected by flow cytometry; and the genomic DNA of both groups were extracted and electrophoresised in agarose gel to examinate the DNA fragments. The results showed hING4 can significantly inhibit the growth of C6 cells by promoting the cell’s apoptosis, which probably is the first one to prove this property of ING4.The experimental and theoretical foundation for gene therapy for gliomas with ING4 in the future was established.

OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.
