Objective To observe therapeutic effect of naoxintong on the patients with cerebral infarction.Methods 69 patients with cerebral infarction were randomly allocated to naoxintong group or control group. All patients were treated with 20ml shuxuening injection into veins and aspirin 100mg once a day, and those in naoxintong group were treated with naoxinting moreover. Neurological deficit scores (NDS) were evaluated before and after 1 month and 2 months of treatment Results Effective rate and notable effective rate of naoxintong group after 2 months of treatment were 97% and 88% ,obviously higher than those of control group 79% and 52%. Conclusion Nongxintong treatment for cerebral infarction was effective.

The orientational projections of sensory fibres of median nerve to the Substantia Gelatinosa (SG) of the spinal cord in rats were studied in accordance with the principle of transganglion degeneration by using the acid phosphatase technique. It was found longitudinally that the afferent fibres of the median nerve projected chiefly to SG from the upper part of C_5 to middle part of T_1. In a few rats, projections extended to middle and lower part of C_4 and lower part of T_1. In comparison with the records in anatomy literature and data from researches with HRP technique, a tendency of pre-positioning was noted. The regional projections of the afferent fibres of median nerve were found within the centre line of SG, and mainly in the region of the medial 1/4-1/2 of the medial half. In the segments of C_7-T_1 of a few rats, the whole area of the medial half of SG was projected. In observing the projections of the afferent fibres of median nerve, it was found that they have a tendency of lateralward increase from cranial portion to caudal portion.

The orientational projections of sensory fibres of radial nerve and ulnar nerve to the substantia gelatinosa(SG) of the spinal cord in rats were studied in accordance with the principle of transganglion degeneration by using the acid phosphatase technique.It was found that the affeernt fibers of the radial nerve projected chiefly to SG, from the upper part of C_6 to the middle part of T_1 longitudinally; the ulnar nerves projected chiefly to SG from the middle part of C_6 to the middle part of T_1.In their transverse projections,the afferent fibres of the radial nerve were mainly found in the region of the whole area of the middle 1/3 of SG; and the afferent fibres of ulnar nerve were found within the centre line of SG, and mainly in the region of the lateral 1/2～3/4 at medial half. In summary, radial nerve projected to the lateral region and ulnar nerve to the medial region of SG.

The orientational projections of the sensory fibres of axillary nerve to the substantia gelationsa (SG) of the spinal cord in rats were studied in accordance with the principle of transgangionic degeneration by using acid phosphatase technique. It was found that the afferent fibers of the axillary nerve projected chiefly to SG from the upper part of C_6 to the lower part of C_8 longitudinally. In a few rats, projections extended to the lower part of C_5 and upper part of T_1. In comparison with the available studies, a tendency of backward localization was noted. As to their transverse projections, the afferent fibres of the axillary nerve were found outside of the midline of SG, and mainly located in the lateral half of SG, at the 1/3 of median and the 1/3 of interior region. In the segments of C_7C_8 of some rats, the medial. 1/2 of the lateral half of SG was projected. It was found that the projection column from up downward had a tendency of extension toward lateral portion.

Objective:To establish a method for the determination of organic residues ( hexane, benzene, toluene, xylene and sty-rene) in macroporous adsorption resins. Methods:Headspace-GC with a DB-624 column was used to determine the residues in macro-porous resins. The inlet temperature was 200℃ and the FID detector temperature was 240℃. The column temperature programming was as follows:the initial temperature was 40℃, maintained for 3 min, and then raised to 200℃ with the rate of 14℃/min and kept for 2 min. The solvent was methyl alcohol and the carrier gas was nitrogen. HPLC was applied to determine the contents of the five resi-dues. Results:The contents of the five organic residues were all below 20‰ in five macroporous resins in common use including D101, HPD100, AB-8, DM301 and NKA-9. Conclusion:The method is simple,accurate and reproducible. It can be used in the res-idue determination of macroporous resins.

ObjectiveTo investigate the diagnosis of acute superior mesenteric venous thrombosis(MVT) by ultrasonography. MethodsSeventeen patients with MVT were confirmed by operation or CT scanning and followed-up, whose ultrasonographic features were analyzed retrospectively. ResultsUltrasonographic features of seventeen patients with MVT were enlarged superior mesenteric vein filled with hypoecho without flow signals( n =9) ,portal vein and(or) splenic vein filled with hypoecho without flow signals (n =4), intestine wall thickening and intestine distension( n =2) and ascites( n =2). The accuracy of ultrasonographic examination for SMV was 65％ (11/17). According to MVT with or without splenic or portal vein involvement,MVT were been classified as two type:large vessel type(n =10) and small vessel type(n =7). The accuracy of ultrasonographic examination for large vessel type and small vessel type were 90％ (9/10) and 29％ (2/7) ,respectively. Patient with large vessel type of MVT were easy to be diagnosed by ultrasonography than those with small vessel type( x2 =3.41, P ＜ 0. 05 ). ConclusionUltrasonography was valuable in diagnosis of MVT, and it played more important role in diagnosis of large vessel type of MVT.

Background:C-MET is expressed in a variety of tumor,and its expression may help to predict the prognosis of patients with gastric cancer. Aims:To explore the association of C-MET protein expression with survival in patients with stage Ⅲ gastric cancer. Methods:A total of 178 consecutive initially treated patients with stage Ⅲ gastric cancer from April 2010 to April 2014 at Beijing Pinggu Hospital were enrolled in this study. The expression of C-MET protein was determined by immunohistochemistry. Kaplan-Meier method was used to analyze the survival in patients with high C-MET protein expression and low C-MET protein expression,COX proportional hazards model was used to analyze the influence of various factors on prognosis. Results:C-MET protein was low expressed in 139 patients(78. 1%),and high expressed in 39 patients(21. 9%). Median survival(25. 1 months vs. 45. 0 months),1-year survival rate(69. 2% vs. 91. 4%),2-year survival rate(41. 0% vs. 84. 0%)were significantly decreased in high C-MET protein expression group than in low C-MET protein expression group(P all <0. 05). C-MET protein expression,N staging,and age were the influencing factor for prognosis of gastric cancer(P all <0. 05),however,gender and tumor differentiation were not related with prognosis(P>0. 05). Conclusions:C-MET protein expression rate is 21. 9% in patients with stageⅢgastric cancer,C-MET expression is significantly associated with survival;1-year survival rate is lower in patients with high C-MET protein expression.
