Objective In order to provide important theoretical basis for further improving design of DC-7/7A high altitude partial pressure suit and FTF-2 air ventilation suit (named as A suit and B suit), the performance of ventilating heat dissipation of DC-7/7A and FTF-2 was studied. Methods Five healthy volunteers were enrolled to took participate in A group and B group tests. Environmental weather conditions for A and B suits were set at Tdb 40℃ and 45℃,rh 45% and 40% respectively, and the test time was 90min and 120 min respectively. Results During the test for A group and B group, Ts ranged from 31.5℃ to 34.5℃ for human comfort. Average skin temperatures of the lower part of the body were from 33.1℃ to 33.8℃. Skin temperatures of the legs did not obviously change or slightly lowered. Heart rate showed an increase of 12 beats/min and 14 beats/min. Sweat quantities were measured to be 0.288?0.056kg/1.5h and 0.445kg?0.077 kg/2h respectively. Evaporation rates were 77.4?3.6% and 84.2?2.4% respectively. Subjective uncomfortable sensation was more obvious as test time went on. Conclusion The results of the ventilating heat dissipation for both groups were quite good, but the findings suggested that the number of the ventilating holes for some important sites should shall be re-considered. Pilots wearing A group and B group with ventilation function would still suffer from mild heat stress and obvious subjective discomfort in hot enviroment.

Diabetic gastroparesis (DGP) is one of the most common complications of diabetes. Acupuncture is an ef-fective treatment for DGP in recent years. Literatures on acupuncture therapy for DGP treatment were screened for the past 10 years. Statistical analysis was made on acupoints used in the literatures in order to find the most com-monly used acupoints and combinations. This article was aimed to explore and summarize the use of the acupuncture law for the better service of clinical practice.

Objective To explore the clinical effect of anteromedial thigh perforator flap for repairing soft tissue defect in lower extremity.Methods From January 2009 to December 2012,12 patients with soft tissue defect of lower extremity were treated with free anteromedial thigh perforator flap.Among them,there were 5 cases of wound in front of tibia,4 cases of dorsal foot wound,3 cases of heel wound;the wound size was 3.0 cm ×3.5 cm-7.0 cm × 9.5 cm;3 cases were repaired with free perforator flap of descending genicular artery,2 cases with free anteromedial thigh perforator flap,and 7 cases with medial vastus muscle perforator flap.Results All the transplants survived.Among them,1 case of anteromedial thigh perforator flap and 1 case of descending genicular artery perforator flap appeared vascular crisis postoperative.After anticoagulation and antispasmodic treatment aggressively,the flaps survived.One case of descending genicular artery perforator flap necrosis in edge,and then were cured by changing dressing.Twelve cases were followed up 6-12 months after operation (average 8.6 months),and the texture of flaps were good,the appearance appropriate ;7 sensation of 5 free flaps after nerve anastomosis came back to S; the donor sites in all cases were sutured directly and healed,leaving only the linear scar,and no effect on function.Conclusion The anatomy of anteromedial thigh perforator flap is constant,and the operation is convenient.The clinical result of repairing soft tissue defect of lower extremity is satisfying.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

OBJECTIVE: To establish a proper experimental model of bone cancer pain in rat for acupuncture research, and observe the pain-relieving effect of electroacupuncture (EA) and/or Celebrex on bone cancer pain in rats. METHODS: The rat model of bone cancer pain was established by percutaneous direct puncture technique and inoculating the rat mammary gland carcinoma cells Walker 256 into tibial medullary cavity directly, and evaluated by detecting the bone tumor growth and mechanical allodynia. The effects of daily EA treatment and/or Celebrex treatment on the rat mechanical allodynia after intratibial Walker 256 inoculation was observed in this study. RESULTS: Significant mechanical allodynia in ipsilateral hind paw and tumor growth in proximal end of tibial bone of rats in the untreated group were observed after intratibial Walker 256 inoculation. The mechanical allodynia thresholds in rats that received EA or 5 mg/(kg.d) Celebrex treatment showed no significant difference as compared with that of rats in the untreated group. However, the mechanical allodynia thresholds of rats in 10 mg/(kg.d) Celebrex group showed significant increase after 22- and 26-day treatment as compared with that in the methyl cellulose (MC) group. There was significant difference between rats with EA combined with 5 mg/(kg.d) Celebrex treatment and rats in the untreated group after 10-, 18- and 23-day treatment. CONCLUSION: EA and 5 mg/(kg.d) Celebrex have synergistic effect on pain relieving and their combined use may enhance the analgesic effect on bone cancer pain.

Objective To report treatment of infectious bone and soft tissue defects caused by tibial shaft fracture of Gustilo type Ⅲ B using free flap and Ilizarov bone transport.Methods Nineteen patients who had suffered from infectious bone and soft tissue defects following tibial shaft fracture of Gustilo type Ⅲ11 B were treated from May 2010 to February 2015.They were 15 men and 4 women,aged from 21 to 58 years (average,45.3 years).Their course of disease ranged from 16 to 21 months,averaging 17.9 months.The area of their infectious defects ranged from 10 cm × 6 cm to 21 cm × 12 cm,and the length of their bone defects from 5 to 11 cm (average,7.4 cm).They were treated with debridement,simple external fixation to reconstruct bony support,coverage of wounds with free flap,and stuffing the dead space with antibiotic concrete beads,followed by Ilizarov bone transport and bone graft after control of infection to reconstruct the defective tibia and function of the affected limb.Results All the flaps survived.Necrosis occurred at the distal margin of one flap but responded to dressing.Pin tract infection occurred in 4 cases but also responded to dressing and antibiotic therapy.Autografts of iliac cancellous bone were implanted into the gliding and traction ends of the bone fragments one month after bone transport had come to rest.All the patients achieved direct bony union.The patients were followed up for an average of 25 months(range,from 19 to 36 months).No secondary fractures or angular deformity was observed.The total treatment time averaged 17.9 months,with no recurrence of infection.According to the Puno score system for functional evaluation at the last follow-up,7 cases were rated as excellent,6 as good and 6 as fair.Conclusion The infectious bone and soft tissue defects caused by tibial shaft fracture of Gustilo type Ⅲ B can be treated by free flap and Ilizarov bone transport,resulting in definitely positive outcomes.
