OBJECTIVETo observe the effect of general anaesthesia with combination of acupuncture [conducted with Han's acupoint nerve stimulator (HANS) applied] and enflurane in radical operation of laryngocarcinoma (LC).

METHODSSixty patients with LC of grade I - II , classified according to the standard of American Society of Anesthesiologists (ASA), were assigned by randomizing number table to the control group and the tested group, 30 patients in each group. The control group received anaesthesia with enflurane alone for inducing and maintaining; the tested group was anaesthetized with enflurane like that given to the control group but also received additionally needling stimulation conducted by HANS. The dosage of enflurane used, the minimum effective concentration of enflurane in alveolar air (MACEnf) and the changes of heart rate (HR) as well as blood pressure (BP) in patients at different time points in the operational process were observed.

RESULTSAs compared with those in the control group, in the tested group, both the MACEnf and the dosage of enflurane were reduced, with the difference between the two groups significant (P<0. 01). The changes of HR and BP among different time points in the tested group were slight, and as compared with those in the control group at the corresponding time points, the difference was significant ( P <0. 05 or P<0.01).

CONCLUSIONGeneral anaesthesia with combination of enflurane and needling conducted by HANS applied in radical operation of LC has definite effect with less complication. Needling could be cooperated with narcotics, and so it could be taken as an auxiliary measure of anaesthesia for radical operation of LC.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

OBJECTIVETo establish a quantitative model for evaluating the degree of the TCM basic syndromes often encountered in patients with primary liver cancer (PLC).

METHODSMedical literatures concerning the clinical investigation and TCM syndrome of PLC were collected and analyzed adopting expert-composed symposium method, and the 100 millimeter scaling was applied in combining with scoring on degree of symptoms to establish a quantitative criterion for symptoms and signs degree classification in patients with PLC. Two models, i.e. the additive model and the additive-multiplicative model, were established by using comprehensive analytic hierarchy process (AHP) as the mathematical tool to estimate the weight of the criterion for evaluating basic syndromes in various layers by specialists. Then the two models were verified in clinical practice and the outcomes were compared with that fuzzy evaluated by specialists.

RESULTSVerification on 459 times/case of PLC showed that the coincidence rate between the outcomes derived from specialists with that from the additive model was 84.53 %, and with that from the additive-multificative model was 62.75 %, the difference between the two showed statistical significance (P<0.01).

CONCLUSIONSIt could be decided that the additive model is the principle model suitable for quantitative evaluation on the degree of TCM basic syndromes in patients with PLC.

OBJECTIVETo study the therapeutic effect of Luohuo Capsule (LHC) clinically.

METHODSClinical trial on 90 patients were carried out adopting randomized, stratified, single-blinded and positive drug controlled method, by divided patients into the treated group (n = 60) and the control group (n = 30). The treated group was treated with LHC, which was mainly consisted of Leech, Radish seed, Water-plantain Tuber, Chuanxiong, etc. The control group was treated with Beijing Hypotensive. No. 0. The therapeutic course was 4 weeks. The diagnosis and efficacy evaluation were in accord with corresponding national standards, using the indexes including safety, clinical symptoms, blood pressure, hemorrheologic parameters, blood lipid, adrenal medullin (AdM) and plasma tissue factor pathway inhibitor (TFPI).

RESULTSThe total effective rate of LHC in lowering blood pressure in the treated group and the control group was 85.00% and 86.67% respectively, comparison of them showed no significant difference (P = 0.915). Most of the improvement of clinical symptoms in the treated group were better than those in the control group (P < 0.05 or P < 0.01). LHC could also improve the hemorrheologic status (P < 0.01), alleviate the blood lipids disorder (P < 0.05), and adjust AdM and TFPI (P < 0.05).

CONCLUSIONLHC is safe in treating hypertension grade I and II with no adverse reaction.

Objective To investigate the clinical value of detecting the serum level of ryanodine receptor antibodies (RyR-Ab) in the diagnosis and evaluation of myasthenia gravis (MG). Methods Enzyme-linked immunosorbent assay (ELISA) and Western blotting were used to detect the serum level of RyR-Ab in 81 patients with MG, 45 non-MG patients with other neurological disorders and 50 healthy control subjects. Results The results of ELISA showed a serum RyR-Ab positivity rate of 23.4% in the in MG patients, significantly higher than the rates in non-MG patients and the healthy subjects (P<0.05). The serum RyR-Ab positivity rate was 77.2% in MG patients with thymoma (MGT), 14.2% in those with thymie atrophy (MGA), and 6.6% in those with thymie hyperplasia (MGH). A positive correlation was found between the titer of serum RyR-Ab and the severity of muscle weakness (r=0.547, P<0.05). Compared with CT scanning, serum RyR-Ab level had low sensitivity (77.2%) but high specificity (91%, P<0.05) for diagnosis of MGT. According to the results of Western blotting, the serum RyR-Ab positivity rate was 81.8% in MGT patients, significantly higher than that in thymomβ-free MG patients and NMG patients (P<0.05). Conclusion RyR-Ab positivity is mainly found in MGT patients, and detection of serum RyR-Ab may help evaluate the severity of MG and assist in CT-based diagnosis of MGT.

OBJECTIVETo study the correlation of polymorphisms of CYP1A1 MSPI and glutathiones S-transferase (GST-M1) independently and in combination with the risk of lung cancer.

METHODSA case control study which included 91 cases of lung cancer and 138 controls collected from the First Affiliated Hospital of Sun Yat-sen University of Medical Sciences, Guangzhou Tumor Hospital and The Red Cross Hospital of Guangzhou or conmunity area. All subjects were investigated with a uniform questionnaire. Blood samples were collected from all cases and controls for detecting CYP1A1 MSPI and GST-M1 polymorphisms which were analyzed by PCR and RFLP.

RESULTSIt showed that there was no significant difference in frequencies of this genotypes of CYP1A1 MSPI between the two groups. The frequency of GST-M1 null (0/0) genotype was higher in the case group than in the control group, with an OR of 1.38 (95% CI 0.81 - 2.38), but there was no statistical significance. However, combination of several genotypes was strongly associated with lung cancer. There was a synergistic interaction between the m2m2 genotype of CYP1A1 MSPI and GST-M1 (0/0) genotype, with an OR of 2.47 (95% CI 1.03 - 5.90).

CONCLUSIONThe combination of two genetic polymorphisms significantly increases the risk of lung cancer.
