Objective To discuss the clinical value of transposition of the pedicled anterolateral femoral periosteal flap. Methods The blood supply of anterolateral femoral periosteum were dissected on 38 adult cadaveric lower limber specimens injected with red dye. The origins, distributions and anastomosis of periosteal breanches were observed and measured. Based on these anatomic investigations, the transposition of pedicled anterolateral femoral periosteal flap was designed to repair the bone nonunion and lesion of femur. Results Twenty-two cases were treated in the satisfactory results, and followed-up from 1 to 5 years. The size of the periosteal flap ranged from 8cm?4cm to 10cm?5cm. Conclusions The periosteal flap could be operated so conveniently and safely as to be spread easily, treatment of lesion and incision of periosteal flap can be finished in the same operative approach. The periosteal flap have been proved to be powerfully clinical value.

Vascular endothelial growth factor (VEGF) is widely used in the research of various diseases. And application of VEGF also has drawn many attentions in spinal cord injury (SCI). This paper reviewed the mechanism of VEGF and different factors that influenced the express of VEGF in SCI.

Patch-clamp is used to study all sorts of ionic channels and their regulations with measuring pA current of cell ionic channel, but the fast capacitance (C-fast) compensation and slow capacitance (C-slow) compensation transient currents are caused by measuring objects and measuring instruments themselves which will change the properties of action potentials. The present paper firstly discusses the C-Fast transient currents affecting membrane capacitance and membrane potential, and then draws a conclusion that the changes of membrane potential affect the properties of action potential through analyzing the changes of membrane potential in H-H model. Based on this conclusion, we discuss the influence mechanisms mainly through the analysis of traditional C-fast compensation errors, and focus discussion on the shape of electrode capacitance affecting C-fast. This method can not only improve the compensation speed greatly, but also improve the compensation precision from the electrode shape as much as possible.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective To investigate the effect of liver cirrhosis on the potency of propofol for sedation in rats. Methods Fifty-eight male SD rats, aged 10-12 weeks, weighing 180-220 g, were randomly divided into 3 groups: control group (group C, n = 18), mild liver cirrhosis group (group M1, n =20) and severe liver cirrhosis group (group M2, n = 20). The model of liver cirrhosis was established using four factors described by Chen et al. After successful establishment of the model, propofol was injected intravenously. The dose of propofol was determined by up-and-down sequential method for loss of righting reflex. The dose of propofol was 5.912 mg/kg in the first rat and the ratio of the doses between the two consecutive rats was 0.85. ED50 of propofol was calculated using up-and-down sequential method. Results ED50 of propofol was significantly lower in group M1 and M2 than in group C and in group M2 than in group M1 ( P ＜ 0.05 or 0.01 ). Conclusion The liver cirrhosis can enhance the potency of propofol for sedation in rats.

Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

OBJECTIVETo investigate the possibility and short-term effect of high dose chemotherapy with peripheral blood stem cell support in the preoperative therapy of breast cancer, and-its influence on the following operation and would healing.

METHODSThree patients with T(3)N(1)M(0) (III(a)), T(4)N(1)M(0) (III(b)), T(4)N(1)M(1) (IV) of breast cancer were diagnosed histopathologically. After receiving HDC/APBSCT, the 3 patients were operated on. HDC/APBSCT process included 2 cycles of FEC induction chemotherapy; PBSC mobilization, APBSC collection and cryopreservation and PBSC infusion; and high-dose chemotherapy, APBSC infusion and supportive therapy. The therapy consisted of CTX2.5 g/m(2), VP-16 600 mg/m(2), and cerboplatin 600 mg/m(2) delivered on day 1, APBSC infusion 48 h later, rhG-CSF (150 microg, BID) was administered 4 h after infusion of APBSC until WBC was higher than 10 x 10(9)/L. During HDC/APBSCT, the patients were protected in the air laminar flow room with supportive therapy of antibiotics, anti-virus and anti-fungus drugs. They left the air laminar flow room after their WBC was greater than 2 x 10(9)/L. Case 1 was treated by radical mastectomy, Case 2 by improved radical mastectomy, Case 3 by improved radical mastectomy and transplantation of skin for the large area.

RESULTSRapid recovery of bone marrow function was observed in all 3 patients. Operation was performed 4 weeks after HDC/PBSCT in Cases 1, 2 and 33 days in Case 3. No influence was seen on operative procedure and would healing, especially in Case 3 with a large area of skin transplantation. Two patients with stage III(a) and III(b) have been alive since the treatment for 30 months and the other with stage IV died of brain metastasis 16 months later.

CONCLUSIONSHDC/APBSCT as a preoperative therapy for breast cancer has no influence on the coming surgery and would healing, even on skin transplantation for a large area. It has a practical response in stage III(a) and III(b), but it is still controversial in stage IV. This method as a salvage therapy for patients with breast cancer of intemuediate or stage.
