OBJECTIVE:To observe the efficacy and safety of levofloxacin and capreomycin combined with chemotherapy regi-men in the treatment of multi-drug resistant tuberculosis(MDR-TB). METHODS:84 MDR-TB patients were randomly divided in-to observation group (42 cases) and control group (42 cases). Observation group received 0.75 g Capreomycin sulfate for injec-tion,addint into 100 ml 0.9% Sodium chloride injection,intravenous infusion,once a day+0.4 g Levofloxacin hydrochloride tab-let,orally,once a day+0.2 g Protionamide tablet,orally,3 times a day+0.3 g Pasiniazid tablet,orally,3 times a day+0.5 g Pyra-zinamide tablet,orally,4 times a day. Control group received 0.4 g Amikacin sulfate injection,adding into 100 ml 0.9% Sodium chloride injection,once a day,intravenous infusion+0.3 g Ofloxacin tablet,orally,twice a day+Protionamide tablet (the same dose with observation group)+Pasiniazid tablet (the same dose with observation group)+Pyrazinamide tablet (the same dose with observation group). All patient were given 0.1 g Glucuronolactone tablet,orally,3 times a day. The treatment course for both group was 12 months. Sputum negative conversion rate,negative conversion time,symptom improvement time,lesion absorption and lung cavity closing,and cell immune indexes (CD4+CD25+/CD4+,CD4+CD25+CD127low/CD4+),IL-17 level before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The sputum negative conversion rate,ab-sorption rate,lung cavity closing and narrowing cases in research group after 3,6,9,12,18 months treatment were significantly higher than control group,sputum negative conversion time,symptom improvement time in observation group were significantly lower than control group,the differences were statistically significant(P<0.05). Before treatment,there were no significant differ-ences in CD4+CD25+/CD4+,CD4+CD25+CD127low/CD4+,IL-17 level in 2 groups(P>0.05). After treatment,CD4+CD25+/CD4+,CD4+CD25+CD127low/CD4+ in 2 groups were significantly lower than before,and observation group was lower than control group,IL-17 level was significantly higher than before,and observation group was higher than control group,the differences were statistically significant (P<0.05). And there was no significant difference in the incidence of adverse reactions in 2 groups (P>0.05). CON-CLUSIONS:Levofloxacin and capreomycin combined with chemotherapy in the treatment of MDR-TB,it can reduce T regulatory cells,increase IL-17 level,do not increase the incidence of adverse reactions.

Objective To investigate the protective effect of Ambroxol against experimental lung ischemia reperfusion (I/R) injury in a situ hilar clamp model.Method Left lung of rat was rendered and ischemic for 90 minutes,and reperfused for up to 2 hours,as the model.Twenty-four SD rats were randomly divided into 3 groups with 8 rats each group:control group,I/R group,I/R and Ambroxol treatment group (AMB group).Rats of AMB group received Ambroxol (25 mg/kg) Intraabdominally 30 minutes before ischemia and intravenously 5 minutes before reperfusion.After 2 hours of reperfusion,blood-gas analysis,the serum level of IL-1?,IL-8 and TNF-?from carotid artery were delected.The wet/dry ratio of lung,the activity of erythrocuprein (SOD),the content of malonaldehyde (MDA) and the activity of myeloperoxidase (MPO) were determined and pathematology changes were observed in the left lung tissue.Differences within the groups were analysed using two-sample t-test. Results After 2 hours of repeffusion,there were no significant changes of artery partial pressure of oxygen (PO_2) and partial pressure of carbon dioxide (PCO_2) among three groups.The wet/dry ratio of lung,the activity of MPO (U/g) and the content of MDA (nmol/mgprot) of I/R group were (5.3?0.5),(1.30?0.26) and (0.66?0.16),significantly higher than those of the control group (P

Objective To investigate the minimal and optimal concentration of ropivacain for epidural anesthesia in patients with breast cancer.Methods 103 patients with breast cancer ASA Ⅰ-Ⅱ undergoing elective radical mastectomy were conducted with epidural anesthesia.T2-3 were selected as a puncture site.A catheter was inserted into the epidural space in a cephalic direction for 3.5-4.0 cm.The concentration of ropivacain was produced by the test of up-down sequential allocation technique.20-25 ml of 0.20 ％ ropivacaine was given after a test of 0.20 ％ 5 ml ropivacaine.If the anesthesia was effective (VAS≤3),the next concentration was down 0.01％,while the VAS was more than 5,the next concentration was up 0.01％.The anesthesia effect and segments of block were measured with acupuncture.Blood pressure (NIBP),heart rates(HR),blood oxygen saturation (SPO2),blood gas and VAS were monitored during operation.Nasal catheter oxygen inhalation was used in routine method.Results The median effective concentration (EC50) of ropivacaine was 0.10 ％ determined by the formula of dixon and massey.The 95 ％ confidence intervals was 0.1022 ％-0.1065 ％.The least and the best analgesic concentration of ropivacaine for the upper thoracic epidural block was 0.14 ％ and 0.17 ％-0.18 ％ respectively.Conclusion The minimal and the optimal analgesic concentration of ropivacaine for the upper thoracic epidural block are 0.14 ％ and 0.17 ％-0.18 ％respectively,and which provides a safe and rational use of ropivacaine for the clinic.

Objective To obtain the classification and characteristics of acupuncture manipulations by analyzing teacher's lifting-thrusting manipulation parameters derived from Germany-made Simi Motion 3D image analysis system using self-organizing feature map neural network (SOM). Method Thirty acupuncture teachers were selected for the study. Unilateral Quchi (LI11) was used as a point for acupuncture. A motion video of lifting-thrusting even reinforcing-reducing, reinforcing and reducing manipulations was made. The video was analyzed using Simi Motion 3D image analysis system to obtain original motion parameters at thumb tip tracking mark point. Teacher's manipulation classification parameters were analyzed using SOM. Result Acupuncture manipulation parameters showed nonnormal distribution with larger dispersion. Even reinforcing-reducing and reinforcing manipulations could be classified into four types and reducing manipulation, into five types. The characteristics of every type showed general concentration degree. Conclusion Acupuncture manipulation parameters overall showed the diversity characteristics of nonnormal distribution and are typical artificial control curve. They have the characteristic of lower concentration degree of neural network classification. Their classification is mainly based on curve shape and cycle length and related to the degree of difficulty of manipulation. This technique can be applied to the quantitative analysis of various manipulationsand the study of technical inheritance and provide reference for the standardization of acupuncture manipulation.
