BACKGROUND:Chinese medicine therapy is effective for patients with mild-to-moderate lumbar spinal stenosis and also has a better long-term effect than surgical patients, which can enhance perioperative efficacy and prevent spinal restenosis. OBJECTIVE:To evaluate the clinical efficacy of “Tongmai songjin yigu” massage therapy on lumbar spinal stenosis. METHODS:Eighty-four patients with degenerative lumbar spinal stenosis were randomly and equaly divided into treatment group and control group. Treatment group were treated with “Tongmai songjin yigu” massage therapy; patients in the control group were treated according to the guidelines for diagnosis and treatment of common disease in orthopedics and traumatology promulgated by China Association of Chinese Medicine, once a day, continuous for 2 weeks. RESULTS AND CONCLUSION:After treatment, the visual analog scale score in the treatment group was improved significantly (P < 0.05), and there was a significant difference in the Japanese Orthopaedic Association Scores on subjective symptom and daily life between the treatment and control groups (P < 0.05). The effective rate of the treatment group was higher than that of the control group (P< 0.05). These findings indicate that “Tongmai songjin yigu” massage therapy is better than traditional massage, but clinical large-sample studies are required.

Objective To observe the status of oxidative stress and activity of alkaline phosphatase(ALP) in rats exposed to high fluoride for the different periods and to analyze the effect of fluoride on the activity of ALP and oxidative stress in fluorosis rats. Methods Twenty-four Wistar rats were divided into control and high-fluoride groups according to their body mass, 12 rats in each group. The control group drank tap water(sodium fluoride concentrations < 1 mg/L), and high-fluoride group drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L). On a standard diet and water available ad hbitum, each rat was measured body weight once a week in 1,4,8,12 week. The biochemical techniques were used to test the indicators of oxidative stress including malonaldehyde(MDA), superoxidedismutase(SOD), glutathione peroxidase(GPx), uric acid and activity of ALP in serum of fluorosis rats. Results There was a interaction between fluoride and time in the activity of ALP (F = 4.690,P < 0.05). The activity of ALP was obviously higher in rats exposed to fluoride for 1,12 week [ (19.29± 3.69), (15.72 ± 0.79)kU/L] compared to the control[ (14.08 ± 1.99),(12.91 ± 3.97)kU/L, all P< 0.05] ; the level of MDA was obviously higher in rats exposed to fluoride for 1,4 week [ ( 13.37 ± 4.38 ), ( 11.82 ± 2.08) μmol/L ] compared to the respective control[ (8.75 ± 3.24), (7.42 ± 2.62)μmol/L, all P < 0.05]; difference of SOD and GPx between control and high-fluoride groups was not statistically significant(all P > 0.05); the level of uric acid in serum was significantly higher in high-fluoride group for 1,4 week[ (89.53 ± 13.21 ), (88.47 ± 19.78 )μmol/L] compared to the control [ (77.79 ± 11.43 ), (65.42 ± i 3.42) μ mol/L, all P < 0.05 ], but the level of uric acid showed lower in high-fluoride group for 8,12 week [(67.21 ± 9.44), (73.95 ± 9.52)μmol/L] compared to the control [(77.79 ± 11.43), (65.42 ± 13.42)μmol/L]. Conclusions Effect of overdose fluoride on ALP is time-dependant. On the other hand,overdose fluoride stimulates the status of oxidative stress in a way unrelated to the exposure period.

OBJECTIVETo isolate and identify the pathogen of Dengue fever from Shenzhen city in 2005 - 2006, and to analyze the molecular characteristics of the isolated Dengue virus strain as well as to explore its possible origin.

METHODSIgM and IgG of serum samples taken from 60 suspected Dengue fever patients were detected by ELISA and immunochromatography, and 9 specimens were positive. Nine samples from patients with early stage Dengue fever were used to isolate virus with C6/36 cell line and the positive cell cultures were identified by MGB fluorescent PCR. The type of isolated virus strain was determined by RT-semi-nested-PCR and fluorescent PCR. E gene of isolated virus strain was amplified by RT-PCR and sequenced. Homology and phylogenetic tree of E gene of Shenzhen Dengue virus with the strains isolated from other areas were constructed.

RESULTSOf nine antibody-positive serum samples, one strain of Dengue virus was successfully isolated. The isolated virus strain was confirmed as Dengue virus type 2 and designated as DEN2-SZ0521. The homology of nucleotide sequence and the deduced amino acid sequence of E gene of SZ0521 with standard type 2 Dengue virus NGC strain was 94.2% and 98.2%, but the homology with standard Dengue virus 1, 3, 4 in the same fragment were 59.1%, 57.2%, 58.5% and 68.1%, 66.7%, 63.2%, respectively. The phylogenetic tree indicated that SZ0521 had the greatest similarity with the Malay0412a/Tw strain and they lied in the same branch of the phylogenetic tree. The corresponding homology of nucleotide sequence and amino acid sequence was 99.8% and 100%, respectively. The isolated Dengue virus type 2 belonged to genotype IV with Indonesia-76, Somalia-84 and Sri Lanka-90.

CONCLUSIONDengue virus was isolated from Shenzhen for the first time, and it was classified as type 2. It was confirmed that the type 2 Dengue virus may come from the epidemic area in Malaysia.

OBJECTIVETo explore the therapeutic methods of fracture and dislocation of coccyx and evaluate its curative effects.

METHODSFrom May 2002 to March 2010,56 patients with fracture and dislocation of coccyx were divided into surgical treatment group and non-surgical treatment group. There were 7 males and 20 females in surgical treatment group with an average age of (48.1 +/- 0.6) years (ranged, 29 to 62 years), treated with open reduction and mini-plate internal fixation. There were 8 males and 21 females in non-surgical treatment group with an average age of (47.5 +/- 0.9) years (ranged, 19 to 54 years),treated with manipulative reduction. All patients were underwent X-ray examination and were finally diagnosed before treatment. Clinical symptoms and Visual Analogue Scales (VAS) of all patients were statistically analyzed before and after treatment.

RESULTSThere was no significant difference between two groups in gender, age, BMI index and VAS evaluation. All patients were followed up from 12 to 25 months with an average of 17.2 months. In surgical treatment group,there were 26 cases with I/a incision and 1 case with II/a incision; the excellent rate of clinical symptom was respectively 92.6% and 100% at leaving hospital and final follow-up; the improvement rate of VAS was 97.6% and was excellent result;internal fixtures were removed at the 1 to 2 years after treatment and no unwell symptoms occurred; VAS of all patients in the group was 0 point. In non-surgical treatment group,the excellent rate of clinical symptom was respectively 72.4% and 82.8% at leaving hospital and final follow-up; the improvement rate of VAS was 72.1% and was good result. There was significant difference in clinical results between two groups (P<0.05).

CONCLUSIONThe results indicated that fracture and dislocation of coccyx should be treated in time. For the treatment of patients with manipulative reduction failures, instability reduction by X-ray examination and serious rectal irritation, open reduction and mini-plate internal fixation can obtain satisfactory results.

BACKGROUNDTelbivudine, one of the five nucleos(t)ide antiviral drugs, was reported to be superior to lamivudine in a better biochemical, virological, and histological response for treatment-naive patients in the GLOBE trial. The aim of this study was to determine the antiviral potency, viral resistance, and the signifcance of early response for long-term telbivudine treatment.

METHODSWe recruited 161 patients of chronic hepatitis B (CHB) on telbivudine between January 2009 and September 2011 in Macau, China. The serum hepatitis B virus DNA levels, hepatitis B e antigen (HBeAg) seroconversion, alanine aminotransferase (ALT) normalization, and viral resistance were analyzed.

RESULTSThe median age and follow-up duration were 48 years and 16.9 months. All patients were followed up for at least 6 months, while data were collected for 132, 120, 95, and 53 patients at 12, 24, 48, and 96 weeks respectively. The cumulative HBeAg seroconversion rate was 20.8% and only three patients (1.9%) presented with telbivudine low level resistance. The ALT normalization rates were 76.9% at 48 weeks and 77.6% at 96 weeks. Undetectable HBV DNA was achieved by 1.8%, 31.6%, 60%, and 74.1% in HBeAg positive patients and 29.3%, 60.3%, 84%, and 84.6% in HBeAg negative patients at each time point. Week 12 HBV DNA level < 1000 copies/ml (< 200 IU/ml) was a better predictor of viral suppression at 2-year follow-up (P = 0.001, OR = 27.00) than undetectable HBV DNA level at week 24 (P = 0.120, OR = 4.81).

CONCLUSIONSTwo-year telbivudine treatment yielded high rates of viral suppression and ALT normalization. Serum HBV DNA level at week 12 is a superior predictor for long-term viral suppression.

OBJECTIVEThe purposes of this thesis were to study the behavior about workers exposed to dust and provide scientific basis for health promotion.

METHODSWe designed a questionnaire and carry it on the 746 dust workers in the 3 representative corporations of Machinery, Ceramic, and Metallurgy Industry. All data were input into computer. And a database was established with Excel. SPSS11.5 statistical analysis software was used to analyze the influence on protecting behavioral between the application of qualifications, different jobs, training or protection, and other aspects etc.

RESULTSThe rates were 94.4% and 75.3% about the regular physical examination and requirements for protective equipment. The rate of choosing an effective way of protection was generally low (15.4%). There was significant difference for among different educational background workers (P < 0.01). The rates of choosing an effective way of protection (20.3%), the regular physical examination (98.3%) and requirements for protective equipment (86.4%) in the dust workers who participated in the training of dust protection were superior than those who did not participated in the training. There was the significant difference (P < 0.05, P < 0.01). There was the significant difference for the rate of effective way of protection, regular physical examination, and requirements for protective equipment among the different corporations (P < 0.05).

CONCLUSIONSDust workers' using rate about the choosing an effective way of protection was generally low in Machinery, Ceramic, and Metallurgy Industry. Those who were not educated had a lower using rate about the protection behavior, regular physical examination, and requirements for protective equipment than those educated.
