In recent years, cytokinesis-block method was used to analyze cytomics indicators including micronucleus, nuclear bridge, nuclear bud, nuclear division index, cell apoptosis and cell necrosis. In public health, it has become the common method to explore the impacts of different population structure, environment and occupational exposure for genomic instability, chromosome breakage, chromosome loss and cell proliferation. This article reviews and discusses the application of using cytokinesis block method to analyze cytomics indicators in public health field.

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 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.

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 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.
