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.

AIM:To observe the effects of granulocyte colony-stimulating factor (G-CSF) on calcium, sodium and potassium ion channel currents of the ischemic atrial myocytes in guinea pig by whole-cell patch clamp technique.METHODS:The guinea pig atrial myocytes were obtained by enzymolysis.Under ischemia and hypoxia condition, whole-cell patch clamp was used to observe the effects of G-CSF at various concentrations on the changes of the I-V curve, activation curve and availability of L-type calcium channel current (ICa,L) and voltage-dependent sodium channel current (INa), as well as I-V curve of delayed rectifier potassium channel current (IK).RESULTS:Under ischemic condition, the I-V curves of ICa,L were changed by acute G-CSF intervention in a dose-dependent fashion.Except for G-CSF at dose of 300 μg/kg, the other concentrations of G-CSF did not change the activation curve and availability of ICa,L, indicating that the effects of G-CSF on ICa,L were in a voltage-independent fashion.The I-V curves of ICa,L under ischemic condition were gradually approaching the normal levels by the higher dose of G-CSF, while the effect of 300 μg/kg G-CSF on ICa,L was similar to 100 μg/kg G-CSF.Acute G-CSF intervention at different doses did not change I-V curve, activation curve, and availability or steady-state availability of INa.As a part of IK, the rapid activating component (IKr) was improved by 100 μg/kg and 300 μg/kg G-CSF intervention with the similar effects, while the slowly activating component (IKs) was not changed by G-CSF.CONCLUSION:G-CSF affects ion channel electrophysiological properties of ischemic atrial myocytes in a voltage-independent but concentration-dependent manner, thus reducing the incidence of atrial arrhythmia.

Objective To explain the physiological properties of serum leucine aminopeptidase (LAP) and discuss the different levels and clinical meaning of serum LAP during the second and the third trimester of gestation.Methods Rate turbidimetry was used to assay serum LAP activity of 175 pregnant women in the second trimester of gestation, among whom 162 were normal and 13 were intrahepatic cholestasis of pregnancy (ICP), and 302 pregnant women in the third trimester of gestation, among whom 215 were normal, 76 were ICP, 6 were pregnancy-induced hypertension syndrome and 5 were premature delivery, and 100 healthy or non-pregnant women.Results Serum LAP activity of pregnant women in the group of the second trimester of gestation was (140.43?64.39) U/L, in the group of the third trimester of the gestation was (234.72?93.53) U/L, and in control group was (72.62?15.31) U/L. The serum LAP activities of the two pregnant groups were much higher than that of control group (P

Objective To examine the effects of Shenqi Bufei Tang decoction on the expression of histone deacetylase-2 ( HDAC2) and nuclear factor-κB p65 ( NF-κB p65) in the airway smooth muscle tissues of COPD rats with lung-qi deficiency syndrome. Methods A total of 40 male rats were randomly divided into normal control group,model control group,Shenqi Bufei Tang decoction group,and aminophylline group.The COPD rat model with lung-qi deficiency syndrome was established by intra-tracheal instillation of lipopolysaccharide (LPS) and passive smoking for 28 days.Pathological changes of lung tissues were ob-served under the light microscope and the thickness of the small airway wall and airway smooth muscle ( ASM) layer analyzed by the image analysis.Immunohistochemistry,real-time PCR and Western blotting were used to detect the expressions of NF-κB p65 and HDAC2 in ASM. Results The thickness of the airway wall and ASM,and the expression levels of NF-κB p65 mRNA and protein were significantly increased in the model control group when compared with those in the normal control group ( P<0.05) . They were significantly reduced and the expression levels of HDAC2 mRNA and protein were markedly increased in Shenqi Bufei Tang decoction group and aminophylline group,which were compared with those in the model group (P<0.05).There were no sig-nificant differences in these indices between Shenqi Bufei Tang decoction group and aminophylline group (P>0.05). Conclu-sion Shenqi Bufei Tang decoction can inhibit the proliferation of ASM in COPD rats with lung-qi deficiency syndrome,which may be associated with the increased expression of HDAC2 and decreased expression of NF-κB p65.
