Objective　To establish the normal growth velocity of fetal liver length and compare them with those of intrauterine growth retardation, pregnant diabetes and maternal-fetal blood types imcopatible. Method　Three hundred and five normal pregnant women and 24, 10, 16 pathological pregnant women of intrauterine growth retardation (IUGR), gestational diabetes and maternal-fetal blood types incompatible respectively had ultrasonographic measurement of fetal liver length at 18 to 42 weeks′ gestation. Results　Normal fetal liver length has a linear relation to gestational age, and showed a significantly rapid increase after 28th week with a growth rate of 1.76 mm per week, and 1.00 mm per week before 28th week (P<0.05). The growth rate of IUGR group before and after therapy were 1.19 mm and 1.23 mm per week, significantly lower than those of normal group (P<0.05). The growth rate of pregnant diabetes group before and after therapy were 1.63 mm and 1.63 mm per week, no statistical significance with normal group (P>0.05). The growth rate of maternal-fetal blood types incompatible group before therapy was 1.98 mm, showed no difference with normal group (P>0.05), but after therapy, the growth rate of fetal liver was 1.38 mm per week, significantly lower than normal group (P<0.05). Conclusion　Dynamic measurement of fetal liver length can help us to understand whether the fetus grow well in uterus and whether the treatments are effective.

OBJECTIVE: To investigate the changes of neuropeptides content in a rat model of spleen-deficiency syndrome. METHODS: Rats were randomly divided into three groups: normal group, untreated group and treatment group. There were ten rats in each group. Spleen-deficiency syndrome was induced by intragastrically administration of rhubarb concentrate in rats of the untreated and treatment group. The rats in the treatment group were intragastrically administered with Sijunzi decoction, a traditional Chinese compound herbal medicine for strengthening spleen and supporting qi. Normal saline was intragastrically administered to the rats in the normal and untreated groups. The somatostatin (SS) and cholecystokinin-8 (CCK-8) content in hypothalamus and colons was detected by the method of radioimmunoassay and the D-xylose content in urine was also detected. RESULTS: The CCK-8 content in hypothalamus of the untreated group was higher than that of the normal group (P<0.05). SS and CCK-8 content in colons of the untreated group was higher than that of the normal group (P<0.05). The CCK-8 content in colons of the untreated group was lower than that of the treatment group (P<0.05). The excretion rate of D-xylose in the untreated group was lower than that of the normal group (P<0.05). CONCLUSION: The disorder of neuroendocrine regulation in rats with spleen-deficiency syndrome may be chiefly responsible for "spleen-deficency and dysfunction of spleen" in traditional Chinese medicine.

Objective To determine the clinical indicators of early death (within 72 hours) in patients with acute paraquat poisoning.Methods The data of 93 acute paraquat poisoning patients admitted to emergency intensive care unit (EICU) of the First Hospital of China Medical University were retrospectively analyzed.The patients were divided into two groups according to whether they died within 72 hours or not.The gender,age,poison dose,paraquat concentration in urine,reduction of paraquat amount in urine after each hemoperfusion,and the worst value of white blood cell (WBC) count,lymphocytes count,arterial blood gas analysis,blood K +,Na+,Cl-,and serum amylase,serum lipase,serum total bilirubin,troponin Ⅰ,creatine kinase (CK),blood urea nitrogen,serum creatinine within 24 hours after poisoning were compared.Spearman correlation analysis was used to analyze the correlation between paraquat concentration in urine and the dose of paraquat.The predictive value of each indicator at death in early stage of poisoning was analyzed with receiver operating characteristic curve (ROC curve).Results Nineteen patients in the group of those died in early stage of poisoning (within 72 hours) resulted in a mortality rate of 20.4％.Compared with non-early death group,in early death group,the value of poison dose (mL:133.4 ± 108.8 vs.58.6 ± 40.0,t=3.145,P=0.002),paraquat concentration in urine [mg/L:16.34 (11.87,96.76) vs.4.46 (1.21,12.78),Z=-3.422,P=0.001],WBC (× 109/L:22.63 ±9.72 vs.14.95 ±8.39,t=3.446,P=0.001),blood lactate [Lac (mmol/L):6.7 (2.2,12.1) vs.1.9 (1.1,3.4),Z=-3.294,P=0.001] were significantly higher,and the reduction rate of paraquat concentration in urine after first perfusion [(38.4 ± 15.63)％ vs.(67.59 ± 27.87)％,t=2.945,P=0.004] and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg=0.133 kPa):28.7 ± 9.3 vs.34.8 ± 6.7,t=-3.245,P=0.002] were significantly lowered.There was no significant difference between two groups in other indexes.Poison dose and paraquat concentration in urine showed significantly positive correlation (r=0.450,P＜0.001).ROC curve showed that the predictive value of paraquat concentration in urine,WBC,and Lac in early death were significant [area under the ROC curve (AUC) of paraquat concentrations in urine was 0.806,95％ confidence interval (95％CI) 0.699-0.913,the cut-off value was 11.64 mg/L,with sensitivity 84.6％,specificity 71.4％; AUC of WBC was 0.734,95％CI 0.569-0.899,the cut-off value was 15.94 × 109/L with sensitivity 69.2％,specificity 76.8％ ; AUC of Lac was 0.729,95％CI 0.568-0.891,the cut-off value was 1.95 mmol/L with sensitivity 84.6％,specificity 42.9％].Conclusions Paraquat concentrations in urine,WBC,Lac,poison dose and PaCO2 were the risk factors of the early death of the acute paraquat poisoning.The research suggests that paraquat concentration in urine,WBC and Lac are valuable in predicting early death of the patients.

Objective The incidence of pancreatic cancer is increasing worldwide, and also in china. The characteristics of the cancer are: short course, rapid progress and high mortality, with median survival time of about 6 months. Unfortunately, the early symptoms of patients are not peculiarity. There are not simple, direct and effective methods of early diagnosis. When the patients have jaundice and abdominal pain, probably they are the advanced disease (stage Ⅲ-Ⅳ) ,with unresectable tumours,and have to perform biliary bypass operation for alleviative treatment. Furthermore, the most of all patients exhibit advanced disease, which is often associated with a reduced performance status, malnourished condition, immune function deficiency, all of which severely limit patients tolerance for toxic chemotherapy regimens. These may result in physiological problems that can alter the metabolism and distribution of cytotoxic drugs and therefor lead to an increase in treatment-related toxicity. Purpose To explore the effect of TPN in the post-palliative operations, Roux-en-Ycholedceho-jejunostomy, of advaneed pancreatic carcinoma patients receiving chemotherapy. Methods From Jan. 1996 to Jan. 1999, 40 cases had receiving combination chemotherapy after palliative operations for relief of jaundice by biliary hypass, and surgical biopsy for histologically cemented. The patients were randomly divided inter 2 groups: (1) treatment group (chemotherapy + TPN), 12 men and 8 women had a median age of 57.8 years old. (2) Control group (chemotherapy + routine treatment), 13 men and 7 women had a median age of 58.2 years old. All the patients received combined chemotherapy, the regimen was 5-Fu+ CF + MMC + DDP/EPI (5-fluorouracil + Calcium folniate + Mitomycin C + Cisplatin or Epirubicin ) or IFN-γ (interferon-γ). Dosages of drugs were modified for bone marrow toxicity, stomatits and declining performance status. After 28 days, the regimen performed once again. The regimen of TPN was: total caloric value (NPC) 20 Kcal/kg·d, nitrogen 0.2kg/kg·d, N/Q = 1g: 125Kcal, Glucose/Fat=6:4. The nutritional & immunological parameters, quality of life, effects of treatment wrer monitored. Results Treatemnt group is superior to control group. After TPN, serum pre. albumin, transferrin concentration, retinol-binding protein, total lymphocyte count, natural killer cells activity, IL-2R+ cells (CD25) percentage of peripheral blood, grades of quality of life and survival time increased significantly (P<0.05, P<0.01 respectively). However, no significant difference was observed in IFN-γ application group (P>0.05). Conelusions The nutritional support can improve nutritional and immune situation and quality of life, and prolong the survival time of the patients, but no relapse-free survival.

The characteristics of distribution, origin and properties of galanin (GAL) were investigated, by using immunocytochemistry (the whole mount stretched pr- eparations and cryostat sections), immunoelectronmicroscopy and microspectroph- ometer measuring techniques. The results showed that (1) All layers of small intestine were rich in GAL- immunoreactive(GAL-I) nerves with a high density in myenteric and submucosal plexuses. (2) A rather high density around the small blood vessels of the small intestine and intestinal crypts were observed. Some GAL-I neurons were seen in the myenteric and submucosal plexuses. Enteric GAL-I nerve fibers seemed to be endogenic and probably related to the regulation of motor function in the gastro- intestinal tract, since there was no obvious reducation of nerve fibers after sec- tion of mesenterium or injection of capsaicin. (3) The distribution and charac- teristics of GAL-I nerve fibers in small intestine indicated that the GAL-I ne- rves might be playing a regulational role in the motion, absorption, secretion and regional blood flow of the gastrointestinal tract.

Objective:To establish a 3 dimensional finite element model of calcaneus and talus for analysing their stress distribution during different gait phases. Methods: CT scanning and computer image processing system were used to establish the model to simulate the situation of calcaneus and talus for 3 phases (heel strike, midstance, push off) during the gait. A finite element solver was used to calculate stress. Results: A three dimensional finite element model of calcaneus and talus was established. And the stress distribution within the bone was obtained and regions with elevated stress at 3 phases were located. The stress distributions of 3 phases were significantly different. The stress increased gradually from heel strike to push off. Conclusion:The model can be used to study biomechanics of calcaneus and talus. The regions of elevated stress of calcaneus and talus are important, which provide an insight into the factors contributing to the fractures and arthritis.

Objective To discuss the pharmaceutical care protocol and methods for clinical pharmacists taking part in cancer pain management. Methods A patient developed delirium and drowsiness after using oxycodone hydrochloride prolonged-release tablet ( OXYCONTIN) and morphine hydrochloride tablet for pain titration treatment. The clinical pharmacist analyzed the reasons of delirium and drowsiness,and suggested a dose reduction of OXYCONTIN or converting OXYCONTIN to another opioid analgesic. Results The suggestion of the clinical pharmacist was partly accepted. After adjusting the treatment, the delirium and drowsiness disappeared gradually, and the pain was well controlled. Conclusion In clinical practice, especially when faced with a rare adverse drug reaction, clinical pharmacists are helpful for ensuring the safety and effectiveness in pain management, as well as improving the level of the treatment, by the implementation of individualized drug therapy.
