Objective　To investigate the diagnosis and treatment of obstructive jaundice (OJ) caused by hepatocellular cacinoma (HCC) invasion to bile duct. Methods　The diagnosis and treatment of 16 cases of OJ caused by HCC in our hospital from January 1989 to December 1998 were retrospectively analysed. Results　Correct diagnosis was made in 2 cases and misdiagnosis in 14 cases preoperatively. 14 cases were operated on, including hepatectomy, enucleation of the tumor in the common bile duct (CBD) and T tube drainage in 2 cases; enucleation of the tumor in CBD and internal stent of T tube drainage in 11 cases; tumor biopsy and T tube drainage in 2 cases; one case died without operation. 15 cases were followed-up for 1 to 14 months postoperatively. The results demonstrated that 14 patients died within 6 months, and only 1 case remained alive for 14 months after operation. Conclusions　The correct diagnosis of this disease could be made for the patients with jaundice accompanied with positive of HbsAg and AFP, local lesions in the liver and the dilated bile duct. B-US, CT, PTC and ERCP are the main examination methods for the diagnosis. The best treatment of this kind of HCC is to remove the hepatic tumor and to recanalize the affected bile ducts.

Objective To compare the results of three methods for measuring C reaction protein.Methods 100 patients were collected from our hospital,and three different methods for measuring C reaction protein were used to analyze the level of C reaction protein.Results Correlation analysis showed that the correlation between immunoturbidimetric assay and immunochromatography was higher.The differences of three methods assayed the C reaction protein were significant (P <0.05 )among normal people by the variance analysis,but had not statistical significance among abnormal people (P >0.05).The differences among all of test peo-ple were significant(P <0.05).Conclusion Detection of C reaction protein was important for diagnose inflammatory diseases.

This paper reported that a new type of floating osmotic pump of ambroxol hydrochloride was designed. Third method apparatus (Chinese Pharmacopeia 2010, appendix XD) was employed to simultaneously evaluate the release and floating behavior in vitro. The system was optimized using central composite design-response surface methodology. Similar factor (f2) between the release profile of self-made formulation and the target release profile was chosen as dependent factor. The amount of glucose (A, mg), pore former (B, %) and weight of coating (C, %) were employed as independent factors. Optimized formulation was: A (100.99 mg), B (1.70%), C (4.21%). The value of f2 (89.14) was higher than that of market capsules (69.02) and self-made tablets (72.15). It was showed that self-made capsules possessed character of zero-order release (r = 0.994 4) and drug release completely (>90%). It was showed in result of in vivo study that tmax and Cmax of self-made capsules were significantly lower than that of market capsules and self-made tablets. The correlation coefficient between the fraction of absorption in vivo and the release rate in vitro was 0.985 1, and relative bioequivalence of self-made capsules was 110.77%. Accordingly, self-made capsules displayed obviously characteristics of controlled release both in vivo and in vitro.

Objective To analyze the long-term results of fractionated stereotactie radiotherapy(FSRT)for the local residual lesion after the first course of radiotherapy for nasopharyngeal carcinoma.Methods From July 1997 to July 2002,46 patients were treated with FSRT.According to the 1992 Fuzhou staging system,the number of patients was 1,6,30 and 9 with stage Ⅰ,Ⅱ,Ⅲ and Ⅳ disease,respectirely;3,11,27 and 5 with T1,T2,T3 and T4 tumor,respectively;14,16,12 and 4 with N0,N1,N2and N3 disease.Radiotherapy was delivered to tumors with the total of dose 68-70 Gy in 7-8w.Chemotherapy(2 cycles of PVF or POF)was given to the patients with stage Ⅲ and Ⅳ a disease.FSRT was given to the residual disease with the total dose of 18-24 Gy in 3 fractions with an interval of 3-7 days.The reference dose line was 70%-90%.Resuits CR and PR rates in this group were 61%and 39%,respectively.The overall survival rates of each year from 1- to 5-year were 100%,87%,83%,78%and 76%.The 1-,3- and 5-year disease-free survival rates were 100%,93%and 89%;The distant metastasis-free survival rates were 100%,85%and 79%;The local-regional control survival rates were 100%,94%and 91%.Seventeen patients who died during the follow-up period were 1 for local cervical lymph node recurrence,2 for fatal nasopharyngeal hemorrhage,4 for local nasopharynx recurrence,and 10 for distance metastases. Conclusions Fraetionated stereotactic radiotherapy is safe and effective for the patients with residual lesion of nasopharyngeal carcinoma at the primary site after radiotherapy.The optimized fractionation and total dose requires the further investigation.

Objective To investgate the application of overall hemostasis potential (OHP) experiment in the high-risk population of prethrombotic state (PTS). Methods The change of absorbance in fibrin formation and degradation was measured with a spectrophotometer at 340 nm when the plasma clotting was triggered by the low concentration of TF in the presence of urokinase. The OHP,overall coagulation potential (OCP) and the overall fibrinolysis potential (OFP) were obtained from the coagulation-fibrinolysis curve based on the computer analysis. To evaluate this OHP method,52 cancer patients,31 coronary artery disease patients,27 mid/late-stage pregnancy women and 100 healthy controls were detected. In addition,the plasma fibrinogen was detected and its correlation with OHP was studied. Results The level of OCP and OHP in PTS high-risk population was significantly higher in cancer,coronary heart disease patients and the mid/late-stage pregnancy women than in the healthy controls (P0.05). Conclusion The OHP assay may indicate the hemostatic balance; therefore,it can be used for evaluation of PTS.

Rats receiving unilateral nigral injection of 6 OHDA resulted in distinct reduction of DA (-88% ) , DOPAC(-80%) and HVA(-60%) in striatum of lesioned side, and the contents of 5HT and 5HIAA remained almost constant in comparison with that of contralateral striatum, suggesting selective lesion of nigrostriatal dopaminer-gic pathway induced by 6OHDA. Following 6OHDA lesion the rats exhibited circling behaviour after APO challenge. 1-Stephaniae ( 1-STP ) significantly antagonizied the action of APO in circling model in dose-dependent manner. Our results indicate that 1-STP possesses the ability to block DA receptor of central nervous system.

Objective To investigate the effect of ketamine on the synaptic long-term potentiation(LTP) in the CA1 area of rat hippocampal slices,and to elucidate the mechanisms underlying the effect of ketamine on memory.Methods Hippocampal slices(400 ?m thick) were obtained from the brains of male Sprague-Dawley rats(2 months old) weighing 200-250 g that were decapitated.The slices were incubated in artificial cerebrospinal fluid(ACSF) at room temperature for at least 120 min before use.Forty-nine slices were randomly divided into 7 groups(n=7):control group,ketamine 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.The slices in each group were performed to record evoked population spikes(PS) using extracellular microelectrode recording technique.Another forty-nine slices were randomly divided into 7 groups(n=7):LTP group,ketamine-LTP 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.PSs were recorded for at least 30 min before LTP in each group.For LTP induction,high-frequency stimulation(HFS) conditioning pulses(100 Hz?s-1) were applied to the Schaffer collateral-commissural pathway of hippocampus using a bipolar stimulating electrode.The changes in PS amplitude after HFS were analyzed in each group.Results The PS amplitude of the rat hippocampal slices in ketamine 1,5,and 10 ?mol?L-1 groups had no significant difference compared with control group.The PS amplitude in ketamine 30,50 and 100 ?mol?L-1 groups decreased compared with control group(P
