OBJECTIVETo observe the effect of tensile stress on human heel skin fibroblast proliferation in vitro, providing a theoretical basis for preventing the wound edge skin necrosis and nonunion after calcaneal fracture surgery.

METHODSFibroblast cells were taken from lateral heel skin of a 40 year-old-man, then cultured and subcultured in vitro. After that, they were divided into three groups: 0 hours group, 6 hours group and 24 hours group and were tested by tensile stress testing. The levels of TGF-β1 and IL-6 in nutrient fluid were measured. Transmission electron microscope and light microscope was applied for observe mitochondria and nucleus.

RESULTSUnder 10% of the tensile stress, mitochondria decreased, the levels of TGF-β1 and IL-6 in nutrient fluid were decreased and cell proliferation was inhibited gradually with time increasing.

CONCLUSIONThe human lateral heel skin in a long-time tensile stress state is an important cause of wound edge skin necrosis and nonunion after calcaneus fracture surgery.

OBJECTIVETo investigate the therapeutic efficacy of Jinshuibao capsules in the treatment of silicosis.

METHODSA total of 270 patients with silicosis were randomly divided into treatment group (n = 141) and control group (n = 129). Both groups received conventional therapy. Additionally, the patients in the treatment group took 3 Jinshuibao capsules three times day for 2-3 courses of treatment (each course = 6 weeks). The therapeutic efficacy and the changes in tumor necrosis factor-α (TNF-α) and transforming growth factor-β(1) (TGF-β(1)) levels were observed after treatment.

RESULTSAfter treatment, cough, expectoration, chest pain, shortness of breath, and other respiratory symptoms were relieved significantly (P < 0.05). The treatment group showed significantly lower TNF-α and TGF-β(1) levels than before treatment and the control group (P < 0.05) and significantly higher forced vital capacity, forced expiratory volume in one second, and maximum mid-expiratory flow than before treatment and the control group (P < 0.05).

CONCLUSIONJinshuibao capsules can decrease inflammatory response, increase vital capacity and maximum voluntary ventilation, reduce airflow limitation, and improve quality of life and thus have good therapeutic efficacy in the treatment of silicosis.

OBJECTIVETo observe the therapeutic efficacy of tetrandrine tablets combined with matrine injection in the treatment of silicosis.

METHODSSixty-three patients with silicosis were randomly divided into treatment group (n = 33) and control group (n = 30). Both groups received anti-inflammatory, cough-relieving, and anti-asthmatic treatment. Meanwhile, the treatment group was given tetrandrine tablets (100 mg bid) and matrine injection (150 mg qd). There were 4 courses of tetrandrine treatment (each course = 3 months), with one-month intervals among them. Matrine injection was used for 15 consecutive days in each month. There were 2 courses of matrine treatment (each course = 3 months), with a one-month interval in between. The clinical symptoms, pulmonary function, serum superoxide dismutase (SOD) activity, and chest X-ray images were observed before and after treatment.

RESULTSAfter treatment, chest distress, chest pain, shortness of breath, and other respiratory symptoms were relieved significantly (P < 0.05). The treatment group showed significantly higher SOD activity than before treatment and the control group (P < 0.05) and significantly higher forced vital capacity and forced expiratory volume in one second than before treatment and the control group (P < 0.05). After treatment, 5 patients (4 stage II cases and 1 stage III case, all in rapidly progressive forms) in the treatment group showed smaller, lighter, and clearer shadows with decreased overall intensity on chest X-ray; 12 patients showed significantly fewer and clearer lung markings on chest X-ray.

CONCLUSIONTetrandrine tablets combined with matrine injection have some therapeutic effect on silicosis.

OBJECTIVETo observe changes of gonad functions of Gan-qi stagnation (GS), Pi deficiency (PD), Gan-qi stagnation Pi deficiency (GSPD) model rats, and the effect of Chaishu Sijun Decoction (CSD) on them.

METHODSRats were randomly divided into 7 groups according to romdom digit table, i.e., the normal control group, the GS model group, the GS medication group, the PD model group, the PD medication group, the GSPD model group,and the GSPD medication group, 10 in each group. Rats in the GS model group, the PD model group, and the GSPD model group were treated with chronic restraint, improper diet +excessive fatigue, chronic restraint +improper diet +excessive fatigue. The model was established for 4 successive weeks. Starting from the 15th day of modeling, CSD at the daily dose of 3.57 g/kg was given by gastrogavage to them for 14 successive days. Equal volume of distilled water was given by gastrogavage to rats in each model group and the normal control group for 14 successive days. The blood contents of gonadotrophin releasing hormone (GnRH), follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and testosterone (T) were detected in rats of each group.

RESULTSCompared with the normal control group, there was statistical difference in GnRH, T, E,, and FSH in the GS, PD, and GSPD model groups (P < 0.05, P < 0.01). The content of LH was elevated in the GS model group (P < 0.05) and declined in the GSPD model group (P < 0.01). Compared with the GS model group, the contents of FSH, LH, and T decreased and E2 increased in the PD model group (all P < 0.05); the contents of FSH and LH also declined in the GSPD model group (P < 0.05). Compared with the PD model group, the T content increased and FSH decreased in the GSPD model group (all P < 0.05). Compared with each corresponding model group, the FSH content decreased (P < 0.01) and LH increased in the GS medication group; the T content increased, E2 and LH decreased (P < 0.05, P < 0.01) in the PD medication group; the T content decreased (P < 0.01), GnRH, E2, FSH, and LH increased (P < 0. 05, P < 0.01) in the GSPD medication group.

CONCLUSIONSThere exist different degrees of abnormal function of the gonad axis in the GS, PD, and GSPD models. CSD had certain regulatory effect on the 3 syndromes. Of them, it showed a more comprehensive role in improving the gonad function axis. Results of this experiment had provided the experimental evidence for higher correlation between CSD and GSPD syndrome.
