ABSTRACT
ObjectiveTo observe the clinical efficacy of qi-blood-supplementing needling in treating the incipient leukopenia after chemotherapy for breast cancer.MethodSeventy-eight patients with incipient leukopenia after chemotherapy for breast cancer were recruited and randomized into a control group (38 cases) and a treatment group (40 cases). The control group was intervened by medications for increasing white blood cell (WBC) count, while the treatment group was by qi-blood-supplementing needling plus the medication. The therapeutic efficacies were evaluated at the end of the intervention.ResultThe WBC counts increased significantly in both groups after treatment (P<0.01), and the count in the treatment group was significantly higher than that in the control group (P<0.05). The total effective rate was 95.0% in the treatment group versus 89.5% in the control group, and the therapeutic efficacy of the treatment group was superior to that of the control group (P<0.05). The treatment group was also better than the control group in improving symptoms including poor appetite, fatigue, pale complexion, and lassitude (P<0.05,P<0.01).ConclusionFor patients with incipient leukopenia after chemotherapy for breast cancer, qi-blood-supplementing needling plus medication for increasing WBC count can up-regulate the WBC count and improve the symptoms due to qi-blood deficiency.
ABSTRACT
Objective To evaluate the significance of combined detection of leptin (LEP),tumor necrosis factor-α (TNF-α),carcino-embryonic antigen (CEA),C-reactive protein (CRP) and interleukin-6 (IL-6) in both serum and pleural effusion in differential diagnosis of tuberculosis and malignant tumor.Methods LEP,TNF-α,CEA,CRP and IL-6 levels in both pleural fluid and serum samples from 95 cases of pleural effusion (including 54 cases of malignant pleural effusion and 41 cases of tuberculous pleural effusion) were detected by immunoturbidimetry and enzyme linked immunosorbent assay (ELISA),respectively.The data with normal distribution and skewed distribution were analyzed by t test and rank sum test,respectively.Results In patients with tuberculosis and malignant tumor,significant difference was observed in serum LEP [(0.42±0.47) ng/ mL vs (1.80±0.91) ng/mL,t=9.666,P=0.0001],TNF-α [(30.88±24.72) pg/mL vs (59.83±30.93) pg/mL,t=4.917,P=0.0001],CEA [(0.22±0.30) ng/mL vs (5.67±3.60) ng/mL,t=ll.074,P=0.0001] and IL-6 [(146.48±54.90) pg/mL vs (20.51±11.62) pg mL,t=-14.449,P 0.0001] levels.Serum CRP levels of patients with tuberculosis and malignant tumor were comparable [(32.78±22.43) mg/mL vs (37.80±16.74) mg/mL,t =1.249,P=0.215].In pleural effusion of the two groups (tuberculous pleural effusion vs malignant pleural effusion),LEP [(0.69±0.65) ng mL vs (4.33±2.16) ng mL,t 11.711,P 0.0001],TNFα [(20.60±17.80) pg/ mL vs (40.40±20.60) pg/mL,t=4.926,P=0.0001],CEA [(0.10±0.17) ng/mL vs (4.02±2.49) ng/ mL,t=11.537,P=0.0001] and IL-6 [(87.80±48.40) pg/mL vs (9.30±5.50) pg/mL,t =-10.333,P=0.0001] levels were significantly different,while CRP levels [(27.34±17.93) mg mL vs (29.60± 13.40) mg mL,t =0.709,P =0.102] were comparable.Conclusion LEP,TNF-α,and CEA levels in both pleural effusion and serum samples from patients with malignant tumor are higher than those with tuberculosis,while IL 6 levels are quite opposite.Combined detection of these parameters can help the differential diagnosis of tuberculous and malignant pleural effusion.
ABSTRACT
Objective To characterize rpoB gene mutations in rifampin-resistant Mycobacterium tuberculosis (M.tuberculosis) in Zhejiang Province.Methods A total of 188 clinical isolates of M.tuberculosis from 188 patients with pulmonary tuberculosis in Tongde Hospital of Zhejiang Province and Integrated Chinese and Western Medicine Hospital of Zhejiang Province were collected.Conventional drug resistance analysis was performed and the mutation of rpoB gene was detected by PCR-based DNA sequencing.The association between gene mutations in rifampin-resistance determining region of M.tuberculosis and clinical resistance was analyzed.Results Fifty-seven out of 188 isolates (30.3％) were drug-resistant strains,including 18 isolates (9.6％) with single-resistance to rifampin,28 isolates (14.9％) with single-resistance to other anti-tuberculosis drugs (10 to isoniazid,12 to streptomycin and 6 to ethambutol),and 11 isolates (5.9％) with multi-drug-resistance (rifampin plus one or more drugs of isoniazid,streptomycin and ethambutol).Among 29 rifampin-resistant strains,rpoB gene mutation existed in 27 strains (93.1％),and the most frequently mutated sites were codons 526 (55.6％,16/27),513 (22.2％,5/27),531 (14.8 ％,4/27)) and 529 (7.4％,2/27).Among 28 strains which were resistant to other anti-tuberculosis drugs,rpoB mutations existed in 4 strains (14.3％),and the mutated sites were codons 526 (2 strains) and 513 (2 strains).All 13 sensitive isolates had no mutation in rpoB gene.Conclusion Rifampin resistance in M.tuberculosis is closely correlated with rpoB gene mutations in Zhejiang province,and the most frequent sites of mutation are at codons 526 and 513.
ABSTRACT
Objective To evaluate the application of different assays for detection of human papillomavirus(HPV)in diagnosis of high grade cervical lesions.Methods Two hundred subjects with abnormal thinprep liquid-based cytology test(TCT)Resultswere selected for HPV DNA detection by hybrid capture 2(HC-Ⅱ) and Methodsbased on PCR including flow-through hybridization and gene chip (HybriMax),real-time fluorescent quantitative PCR(FQ-PCR)and flow fluorescent hybridization assay.Cytopathological Resultswere used as gold standards to evaluate the test performance of the above assays for diagnosing cervical intraepithelial neoplasia(CIN)≥Ⅱ. SPSS 13.0 software was used for statistical analysis.Results HPV DNA positive rates of 200 samples by HybriMax,FQ-PCR,flow fluorescent hybridization assay and HC-Ⅱ were 72.5%(145/200),71.5%(143/200),70.0%(140/200)and 69.0%(138/200),respectively,and the differences were not statistically si(g)nificant(x2 =0.252,0134,0.012 and 0.027,P ＞ 0.05).The sensitivity,Youden index and negative predictive value of the above assays were statistically different(x2 =7.923,7.819 and 8.108,P ＜0.05).Conclusion HC-Ⅱ is superior to PCR Methodsin diagnosis of CIN Ⅱ and above.
