Objective: To investigate the efficacy of specific point acupuncture and manipulative adjustment on muscle strength of the knee osteoarthritis. Method: One hundred and five patients were randomly allocated to two groups. Sixty-eight cases in the treatment group were treated by specific point acupuncture and manipulative adjustment on muscle strength of the knee joint. While 37 cases in the control group were treated with specific point acupuncture alone. Result: The total effective rate was significantly higher in the treatment group than in the control group (P＜0.05). Conclusion: Specific point acupuncture and manipulative adjustment on muscle strength of the knee joint has a satisfactory curative effect on knee osteoarthritis.

Objective To analyze the characteristics of bone scintigraphy in 117 cases with primary hyperparathyroidism (PHPT).Methods Of these 117 cases (50 males and 67 females),there were 116 parathyroid adenomas and 1 parathyroid cancer.Mean age was 61.1(12-86) years old.All had ~(99)Tc~m-methylene diphosphonate (MDP) bone scintigraphy.The bone images could be classified into 4 categories.Category Ⅰ:normal;category Ⅱ:localized abnormal,which could be subcategorized as Ⅱ A with skull and mandible involvement,and Ⅱ B with Ⅱ A characteristics plus metabolic derangement;category Ⅲ:systemic,whole-body incmased tracer uptake;category Ⅳ:systemic plus localized metabolic derangement.Data were analyzed statistically with X~2 and t-test (isolated samples).Results According to the scintigraphic findings,there were 47 cases(40.17%)of category Ⅰ,35 cases(29.91%) category Ⅱ (21/35cases Ⅱ A and 14/35 cases Ⅱ B),30 cases (25.64%) category Ⅲ,and 5 cases (4.27%) category Ⅳ.Combining categories Ⅱ、Ⅲ and Ⅳ together,there were 70 abnormal cases.These patients had history of abnormal bone images such as bone fracture (39 cases,55.71%),calculus (8 cases,11.43%),bone fracture plus calculus(7 cases,10.00%),osteoporosis (51 cases,72.86%) or ostalgia(26 cases,37.14%);however,in the 47 cases of category Ⅰ,only 1 (2.13%),0,0,10(21.28%)and 10 cases (21.28%),respectively,were found.Therefore.these case history characteristics were statistically significant (X~2=11.152,P=0.01).The tumor size,parathyroid hormone (PTH),blood calcium,blood phosphorus in the patients of abnormal PHPT categories Ⅱ to Ⅲ were(14.52±13.72)cm~3,(731.67±618.40)ng/L,(3.05±0.29) mmol/L and (0.71±0.14) mmol/L,respectively.with statistically significant difference compared to category Ⅰ:(0.78±1.33) cm~3,(112.04±62.98)ng/L,(2.56±0.42) mmol/L and (1.03±0.36)mmol/L(t=-5.724,-5.741,-7.274 and -6.451;all P＜0.01).Conclusions (1)Bone scintigraphy was normal in 40% of PHPT patients.(2)The bone images of PHPT could be classified into 4 categories and each could reflect the duration and severity of the disease status on bone.(3)The bone imaging characteristic could be useful for differential diagnostic purposes.

Objective To establish written and electronic archives of Schistosoma japonicum antibody indirect hemagglutina-tion(IHA)tests. Methods In the process of schistosomiasis screening by IHA,the written records,electronic records,and se-rum sample bank were combined to make comprehensive archives. Results The S. japonicum antibody IHA test archives can pre-serve the schistosomiasis screening data in the long term and even can trace the source of experiments,and the operation was sim-ple. Conclusion The archives of S. japonicum antibody IHA tests are simple and useful,and worth of popularization.

OBJECTIVETo investigate the proliferation inhibition and the differentiation effects of realgar (As4S4) nano-particles on human acute myeloid leukemia cell line HL-60.

METHODCell viability was determined by MTT and PI-stained cell cycle assays. The realgar induced morphological changes on cells were examined after Wright-Giemsa staining. The cell differentiation was evaluated with NBT and specific cell surface antigen (CD11b and CD14) expression assays.

RESULTHL-60 cells exhibited obvious morphological features of differentiation after the realgar treatment. A 24 h incubation of the cells with 0.25-1.0 micromol x L(-1) realgar caused a great increase in NBT reduction ability. The expressions of CD11b and CD14 were augmented in cells treated with 0.50 micromol x L(-1) realgar for 48 h, and cell cycles were arrested in G1 phase.

CONCLUSIONLow dose realgar induces differentiation in human acute myeloid leukemia cell line HL-60.

Objective To establish the linear regression equation between body height and com bined length of manubrium and mesosternum of sternum m easured by CTvolum e rendering technique (CT-VRT) in southw est H an population. Methods One hundred and sixty subjects, including 80 m ales and 80 fem ales w ere selected from southw est H an population for routine CT-VRT(reconstruction thickness 1 m m ) ex-am ination. The lengths of both manubrium and mesosternum w ere recorded, and the com bined length of manubrium and mesosternum was equal to the algebraic sum of them . The sex-specific linear regression equations between the com bined length of manubrium and mesosternum and the real body height of each subject w ere deduced. Results The sex-specific sim ple linear regression equations between the com bined length of manubrium and mesosternum (x3) and body height (y) w ere established (m ale:y=135.000+2.118x3 and fem ale:y=120.790+2.808x3).Both equations show ed statisticalsignificance (P<0.05) w ith a 100% predictive accuracy. Conclusion CT-VRTis an effective m ethod for m easurem ent of the index of sternum . The com bined length of manubrium and mesosternum from CT-VRTcan be used for body height estim ation in southw est H an population.
