Objective The purpose of this paper was to evaluate the clinical value of double-contrast barium(DCB) combined with CT in the diagnosis of gastric carcinoma.Methods 112 patients with gastric carcinoma confirmed by surgery and pathology between 1990 and 1997 were included.69 patients took DCB of the upper gastric intestinal tract.43 patients were given CT scans,in whom 32 patients took DCB before CT.Results The accuracy of gastric carcinoma staging determined by DCB were 91.3%.The accordant rate of gross type of gastric carcinoma determined by DCB and the combined way were respectively 67.74% and 72.41%,superior to CT(47.22%,?

BACKGROUND: Therapeutic methods for of peripheral facial nerve injury include surgery, physical therapy and drug treatment, but the treatment effect is not ideal in some certain cases. OBJECTIVE: To study the effect of autologous platelet rich plasma on repair of facial nerve injury. METHODS: The bilateral destroyed buccal nerve branches of the 10 white rabbits were put in silica gel nerve regeneration chamber, one side injected with platelet rich plasma as experimental group, the other side injected with normal saline as control group. The general observation, neuroelectrophysiology detection, histological observation, image analysis and evaluation of facial nerve regeneration recovery were performed at 8 weeks after surgery. RESULTS AND CONCLUSION: The action potential latency of the orbicularis oris at the experimental side was significantly lower than that at the control side, and the action potential amplitude (M wave) of compound nerve muscle of the experimental side was significantly higher than that of the control side (P < 0.01). Compared with the control side, the regenerative nerves of the experimental side were more mature with more regenerative axons, and the differentiation of myelin sheath was more mature and the thickness of myelin sheath was wel -distributed. Meanwhile, the diameters of axons were closed to the normal diameter, and the nerve axons were more intensive and arranged more regularly, the outer membrane of nerve fiber was thicker and the col agen fiber and elastic fiber layer were increased when compared with the control group. The number of regenerative axons of the control side was less, and the axons were distributed irregularly and poorly developed, and a large number of fibrous connective tissues were observed. The vacuolar degeneration at the control side was more than the experimental side. The regenerated nerve in the experimental side was better than the control side in the diameter of myelinated axon, area, myelin sheath thickness and axon count, and there were significant differences between two groups (P < 0.01). It indicates that platelet rich plasma has a promoting effect in the repair and regeneration of facial nerve.

Objective To investigate the clinical curative effect of Zhuanggu-Huoxue-Buyang decoction combined with negative pressure seal flushing drainage treatment for traumatic osteomyelitis. Methods According to the random number method, 132 patients with traumatic marrow from June 2015 to June 2016 in our hospital were divided into the control group and research group with 66 cases in each group. The patients of control group were treated with negative pressure seal flushing drainage, and the patients of research group were given to Zhuanggu-Huoxue-Buyang decoction on the basis of control group.Both groups were treated for 15 days. The clinical effective rate and clinically relevant indicators were counted, which included fracture healing time, granulation, covering time, average length of hospital stay, antibiotic use time, the negative pressure drainage time and positive rate of bacteria. At the same time patients complications were observed during the treatment. In addition, the recurrence rate of two groups was in the following half a year.Results The clinical effective rate of patients in the research group [95.5% (63/66) vs. 83.3% (55/66), χ2=5.114]was significantly higher than control group(P<0.05).The fracture healing time of patients in research group(5.3 ±1.1 months vs.7.6 ±1.9 months,t=-8.705)was significantly lower than the control group(P<0.05). The granulation covering time of patients in research group (27.8 ± 5.6 d vs.35.1 ± 6.4 d,t=-6.961) was significantly lower than the control group (P<0.05). The average length of hospital stay of patients in research group (31.2 ± 4.3 d vs.39.2 ± 5.1 d,t=-9.870) was significantly lower than the control group (P<0.05). The antibiotic use time of patients in research group(8.9 ±2.0 d vs.13.3 ±3.9 d,t=-8.152)was significantly lower than the control group (P<0.05). The negative pressure drainage time of patients in research group (13.6 ± 3.3 d vs.19.2 ± 4.2 d,t=8.744)was significantly lower than the control group(P<0.05).The culture positive rate of patients in research group[6.1%(4/66)d vs.18.2%(12/66),χ 2=4.552]was significantly lower than the control group(P<0.05).The rate of complications of patients in control group[18.2%(12/66)vs.4.6%(3/66),χ 2=6.092] was significantly higher than the research group (P<0.05). The relapse rate of patients in control group [21.8% (12/55)vs.7.9%(5/63),χ 2=4.589]was significantly higher than the research group(P<0.05).Conclusions The Zhuanggu-Huoxue-Buyang decoction combined with negative pressure seal flushing drainage treatment improves clinical indicators and reduces the incidence of complications and the recurrence rate.
