Objective: To investigate the cinlical features and therapeutic methods of unex-pected gallbladder carcinoma. Methods: A retrospective analysis was performed in 19 cases of unexpected gallbladder carcinoma treated in our hospital from April 2002 to April 2008. Results: Ten cases in early stage were perfomed gallbaldder resection and local lymph node removal, and the average survival time was 18.7 months; 4 cases were perfomed extend radical resection, and the average survival time was 12.3 months; 5 cases were performed palliative resection, and the survival time was less than 6 months. Conclusions: Frozen section examination during opera-tion is key to diagnose unexpected gallbladder carcinoma. Radical resection is the first option once the diagnosis is confirmed, and the method can be decided according to Nevin classification and B ultrosound scaning during opreation.

OBJECTIVE: To study the protective efffects of Chailing Guiqi Decoction (CLGQD) combined with lumbrukinase on renal function in rats with adriamycin nephropathy. METHODS: Thirty-six SD rats were randomly divided into four groups: normal control group, untreated group, simvastatin-treated group and CLGQD -treated group. Adriamycin nephropathy was induced by intravenous injection with 5 mg/kg adriamycin. After seven-day treatment, quantitative measurement of 24-h urine protein was determined with trichloroacetic acid, and serum total protein (TP), albumin (Alb), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine (Cr) and blood urea nitrogen (BUN) were assessed using automatic biochemistry analyzer. The pathomorphological changes of renal tissues were observed with light and electron microscopes. RESULTS: In the untreated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly higher than those in the normal control group (P<0.05 or P<0.01), while the serum TP, Alb, HDL were significantly lower than those in the normal control group (P<0.01). In the CLGQD-treated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly lower as compared with those in the untreated group (P<0.05 or P<0.01), while the serum TP, Alb and HDL were significantly higher as compared with those in the untreated group (P<0.05 or P<0.01). The pathomorphological findings of the renal tissues under the light microscope in the untreated group showed focal segmental glomerulosclerosis in a few of glomerulus, degenerated and swelled proximal tubular epithelial cells, proteins in cast formation in some renal tubules and scattered fibrosis in interstitial tissues of the kidney, while the electron microscope images showed the fusion of foot processes in glomerular epithelial cells. The pathomorphological changes in the CLGQD-treated group were slighter than those in the untreated group. CONCLUSION: CLGQD combined with lumbrukinase can reduce proteinuria, regulate lipid metabolism, protect renal function, and delay progressive renal damage in rats.

Objective To investigate the relationship between acute biliary pancreatitis and pancreaticobiliary maljunction and the role of magnetic resonance cholangiopancreatography(MRCP) in evaluation of pancreatico biliary maljunction.Methods To compare the liver function indicators of different groups of acute biliary pancreatitis patients(153 cases) associated with pancreatico biliary maljunction and without pancreatico biliary maljunction before and after the conservative treatment.Results The 32 acute biliary pancreatitis patients with pancreatico biliary maljunction detected by MRCP were compared with the 121 cases without pancreatico biliary maljunction.The ALT,AST,GGT after conservative treatment in both group of pancreatico biliary maljunction and Npancreatico biliary maljunction were significantly decreased (P ＜ 0.05).ALT,AST and GGT of pancreatico biliary maljunction group were higher than that of Npancreatico biliary maljunction group with statistical significance (P ＜ 0.05).Conclusions MRCP as a noninvasive cholangiopancreatography study of pancreatico biliary maljunction is a safe and reliable examination method,pancreatico biliary maljunction is one of the important causes of acute biliary pancreatitis.

OBJECTIVE:To provide reference for the formulation of individualized treatment plan for patients with cardiogenic ischemic stroke. METHODS:For a patient with cardiogenic ischemic stroke,clinical pharmacists adjusted lipid-lowering scheme according to disease progress combined with treatment principle of ischemic stroke and cardiogenic ischemic stroke;recommended second-level prevention and assisted physicians to adjust anti-infective plan according to individual situation of patient. When patients suffered from liver dysfunction,it was recommended to stop using drugs that may cause liver dysfunction,detect renal function damage early,analyze renal function impairment caused by insufficient fluid circulation,timely supplement fluid and provide whole-process pharmaceutical care in respects of anticoagulation, lipid-lowering and anti infection treatment, etc. RESULTS:Physician adopted the recommend of pharmacists and they formulated individualized treatment plan for cardiogenic ischemic stroke patients together;liver and kidney function recovered,and the condition of patient was improved. INR control (1.8)was better at discharge,and discharged education was provided for the patients at the same time. CONCLUSIONS:Clinical pharmacists participate in the treatment for the patient with cardiogenic ischemic stroke and assist physicians to optimize treatment plan according to disease condition. When ADR occurs,timely adjustment of treatment plan ensures the safety and effectiveness of patient medication.

OBJECTIVE:To study the preventive effect of Qingnao tablet on cerebral ischemia-reperfusion injury in rats. METHODS:Rats were randomly divided into sham operation group,model group,Naoluotong capsule group (positive control, 0.05 g/kg),Qingnao tablet high-dose,medium-dose,low-dose groups(1.52,0.76,0.38 g/kg),10 in each group. Rats in all ad-ministration groups were intragastrically given relevant medicines,rats in sham operation group and model group were intragastrical-ly given equal volume of sodium carboxymethylcellulose solution,once a day,for 5 d. After 1 h of last administration,all rats were induced for cerebral ischemia-reperfusion injury model by suture-occluded method except for sham operation group. After 22 h of ischemia-reperfusion,neurological function deficit scoring was conducted;the pathological changes of the hippocampus were ob-served;superoxide dismutase (SOD),adenosine triphosphate (ATP),lactate dehydrogenase (LDH),tumor necrosis factor α(TNF-α)levels in brain tissue were measured. RESULTS:Compared with sham operation group,rats in model group appeared dif-ferent degrees of neurological deficits(score declined),sparse neurons,irregularly arranged in hippocampus as well as other patho-logical changes;ATP,SOD levels in brain tissue were decreased(P<0.01),LDH,TNF-α levels were increased(P<0.01). Com-pared with model group,neurological function deficit scores in Qingnao tablet doses groups were increased(P<0.05),neurologi-cal deficits were improved. Except for sham operation group,brain tissue indexes in other administration groups were significantly improved(P<0.05 or P<0.01). CONCLUSIONS:Qingnao tablet can increase ATP and SOD levels in brain tissue homogenate of model rats with cerebral ischemia-reperfusion,decrease LDH and TNF-α levels,and obviously improve rats'cerebral ischemia-re-perfusion injury.

Objective: To explore the parameters used for the clinical evaluation of post-trau- matic hepatic function crashing down to the ground. Methods: By establishing the animal model of liver impact injury in simulation of parachuter,blood were sampled before injuries and 15 min, 30 min,45 min,1 h, 3 h, 6 h ,9 h after injuries. Cytokines including TNF?、IL-2 and liver function parameters including ALT,AST,LD-L,GGT,ALP were measured and analyzed statistically.

The different concentration of specific ion species and the electrodiffusion of the ions down their electrochemical gradient generate transmembrane potential. The regulation of membrane potential for the function of numerous membrane proteins such as ion channels, transporters, pumps and enzymes plays primary role in the conversion of extracellular electric stimulation into a sequence of intracellular biochemical signals. Some ion channels regulated by membrane potential are well known, and the membrane non-ion channels protein is also modulated physiologically by membrane potential.

OBJECTIVE: To observe the effects of salvianolate on rats with postoperative intestinal adhesion and to explore the prevention mechanism. METHODS: Forty SD male rats with intestinal adhesion were randomly divided into four groups: untreated group, low-dose salvianolate-treated group (12 mg/kg), medium-dose salvianolate-treated group (24 mg/kg) and high-dose salvianolate-treated group (48 mg/kg), with another ten SD male rats as normal control. Intraperitoneal injection of glucose was administered to the rats in the normal control group and the untreated group, and intraperitoneal injection of salvianolate was administered to the rats in the low-, medium- and high-dose salvianolate-treated groups. They were all treated for 8 days and once a day. On the eighth day after surgery the blood samples of each group were collected. Grades of intestinal adhesion were ranked by macroscopic observation. The adhesive tissues between viscera and belly wall were taken for pathological observation. The levels of interleukin-1beta (IL-1beta), interleukin-4 (IL-4) and tumor necrosis factor-alpha (TNF-alpha) were determined by enzyme linked immunosorbent assay. RESULTS: Salvianolate can significantly reduce the extent of postoperative intestinal adhesion, obviously decrease the levels of IL-1beta, TNF-alpha and inhibit the hyperplasy of fibrous connective tissue. However, there was no significant impact on the level of IL-4. CONCLUSION: Salvianolate can reduce the extent of postoperative intestinal adhesion, decrease the expression of IL-1beta and TNF-alpha and inhibit the hyperplasy of fibrous connective tissue. This may be the mechanism of salvianolate in preventing intestinal adhesion.
