BACKGROUND: Long-term radioactive ray accumulation leads to surrounding tissues fibrosis accompanied by limitation of mouth-opening, which seriously affects life quality of tumor patients. OBJECTIVE: To observe pathological change of soft tissues in rats with radiation masseter injury and the level of transforming growth factor β1 (TGF-β1) mRNA expression in vivo.METHODS: A total of 30 Wistar rats were randomly divided into control group (n=10) and radiated group (n=20). Radiated group were radiated with linear accelerator at a dose of 40 Gy. The pathological changes of vessels were observed under light microscope and electron microscope and expression of TGF-β1 was detected by RT-PCR. RESULTS AND CONCLUSION: The microvessel density of radiated group was obviously decreased than that of the control group (P < 0.01), but the mRNA expression of was higher than that in the control group (P < 0.01). It suggests that radiated injury can induce fibrosis to repair the radiated injury.

Objective: To observe the therapeutic efficacy of Fu's subcutaneous needling (FSN) in treating scapulohumeral periarthritis (SP). Methods: Eighty patients with SP were randomly divided into an observation group and a control group, 40 cases in each group. Patients in the observation group received FSN treatment while those in the control group received conventional acupuncture treatment. Visual analogue scale (VAS) and range of motion (ROM) were observed before and after the treatment, and the therapeutic efficacy was also evaluated. Results: After the treatment, the VAS scores decreased significantly in the two groups, and the VAS score in the observation group was significantly lower than that in the control group (P<0.01). After the treatment, the ROM increased significantly in both groups (both P<0.01), and the ROM in the observation group was significantly higher than that in the control group (P<0.01). The recovery rate and the total effective rate in the observation group were respectively 40.0% and 95.0%, significantly higher than 12.5% and 77.5% in the control group (P<0.01, P<0.05). Conclusion: FSN can effectively relieve pain and improve the joint motion in treating SP, thus offering a novel option to the treatment of this kind of musculoskeletal disorder.

Objective To study the effect of Tibet medicine of Herba Lamiophlomis rotata on promoting hemostasis and blood coagulation and to explore its mechanism. Methods High dose(2 g/kg),middle dose(1 g/kg) and low dose (0.5 g/kg) of the aqueous extract from Herba Lamiophlomis rotata(HLRE)were given to mice by gastric gavage for 3 days,and then bleeding time (BT),clotting time(CT) and platelet count(PLC)were determined. Different doses of HLRE(3,1.5,0.75 g/kg)were administered by gastric gavage to rats for 14 days,and then blood samples were collected from common carotid artery for the determination of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time(TT),fibrinogen(FIB),hepatic function and blood lipid indexes. Results Compared to the blank control group,the bleeding time and clotting time were obviously shortened in 2g/kg HLRE and 1g/kg HLRE groups and positive control group,but the difference of PLC was insignificant. PT and APTT values in all of the treatment groups did not differ from those in the blank control group. However, TT values were obviously shortened in 3 g/kg HLRE group,FIB and Albumen(Alb)values increased,the aminotransferase and blood lipid values tended to decrease. Conclusion The aqueous extract from Herba Lamiophlomis rotata has an effect on promoting hemostasis and blood coagulation ,and its mechanisms may be related to the increase of FIB and Alb contents and the shortening of TT value.
