BACKGROUND:Clinicaly, patients with constipation often have depression and depression is often associated with symptoms of constipation, but the mechanisms remain unclear. OBJECTIVE:To observe the relation between constipation and depression by establishing animal models. METHODS:A total of 60 specific-pathogen-free rats were divided randomly into three groups: normal group, chronic stress-induced depression model group and slow transit constipation model group. Slow transit constipation model was created by giving the solution of compound diphenoxlate 8 mg/kg daily, for 120 consecutive days. On day 100, chronic stress model rats were subjected to successive unforeseen stimulus for 21 days. Rats in the normal group were regularly housed. Fecal number, dry weight of feces and body weight were recorded once a week. After successful model establishment, fecal number, dry weight of feces, time of first dark stools defecation, sucrose preference, open-field behavior score and forced swim time were detected in each group, and statisticaly analyzed. RESULTS AND CONCLUSION:Fecal number was less in the chronic stress-induced depression model group than in the normal group (P = 0.00), and time of first dark stools defecation was longer (P = 0.00). Fecal number was more in the chronic stress-induced depression model group than in the slow transit constipation model group (P = 0.00), but time of first dark stools defecation was shorter (P = 0.00). No significant difference in fluid consumption, sucrose preference, horizontal and vertical scores of open-field test, and forced swim time was detected between slow transit constipation model group and normal group (P > 0.05). However, above indexes were higher in the slow transit constipation model group than in the chronic stress-induced depression model group (P < 0.01). Results verified that constipation was observed in chronic stress-induced rat model, but depression was not observed in slow transit constipation rat model, suggesting that depression can induce constipation, but constipation does not necessarily lead to depression.

Objective To evaluate the effects of prophylactic cranial irradiation (PCI) on the survival and brain metastatic rates in patients with limited stage small cell lung cancer (SCLC) in complete remission. Methods Fifty one patients with limited stage SCLC in complete remission after chemoradiotherapy were randomly divided into prophylactic cranial irradiation (PCI) group (n=26) and control group (n=25). Patients in PCI group received irradiation to a dose of 25.2~30.6?Gy by 1.8~2.0?Gy per fraction. With the survival rates of the two groups analyzed by life table and compared by Log Rank test, the difference in cranial metastatic rates between the two groups were tested by ? 2 test. The patients' clinical features such as age, sex, effect of treatment before PCI were comparable between the two groups. Results The incidence of cranial metastasis was 3.8% in the PCI group as compared with 32.0% in the control group, with the difference significant (? 2=5.15, P= 0.02 ). The 1 , 3 , 5 year survival rates were 84.6%, 42.3%, 34.6% in the PCI group and 72.0%, 32.0%, 24.0% in the control group, with no significant difference between the two groups (? 2=2.25, P=0.13). No serious complications were observed in patients who received PCI. Conclusion For patients with limited stage SCLC complete response after chemoradiotherapy, PCI can decrease the incidence of cranial metastasis and tends to improve the survival rate.

OBJECTIVETo investigate the effects of nano-lead exposure on learning and memory and iron homeostasis in the brain of the offspring rats on postnatal day 21 (PND21) and postnatal day 42 (PND42).
METHODSTwenty adult pregnant female Sprague-Dawley rats were randomly divided into control group and nano-lead group. Rats in the nano-lead group were orally administrated 10 mg/kg nano-lead, while rats in the control group were administrated an equal volume of normal saline until PND21. On PND21, the offspring rats were weaned and given the same treatment as the pregnant rats until 42 days after birth. The learning and memory ability of offspring rats on PND21 and PND42 was evaluated by Morris water maze test. The hippocampus and cortex s amples of offspring rats on PND21 and PND42 were collected to determine iron and lead levels in the hippocampus and cortex by inductively coupled plasma-mass spectrometry. The distributions of iron in the hippocampus and cortex were observed by Perl's iron staining. The expression levels of ferritin, ferroportin 1 (FPN1), hephaestin (HP), and ceruloplasmin (CP) were measured by enzyme-linked immunosorbent assay.
RESULTSAfter nano-lead exposure, the iron content in the cortex of offspring rats on PND21 and PND42 in the nano-lead group was significantly higher than those in the control group (32.63 ± 6.03 µg/g vs 27.04 ± 5.82 µg/g, P<0.05; 46.20 ±10.60 µg/g vs 36.61 ± 10.2µg/g, P<0.05). The iron content in the hippocampus of offspring rats on PND42 in the nano-lead group was significantly higher than that in the control group (56.9 ± 4.37µg/g vs 37.71 ± 6.92µg/g, P<0.05). The Perl's staining showed massive iron deposition in the cortex and hippocampus in the nano-lead group. FPNl level in the cotfex of offspring rats on PND21 in the nano-lead group was significantly lower than that in the control group (3.64 ± 0.23 ng/g vs 4.99 ± 0.95 ng/g, P<0.05). FPN1 level in the hippocampus of offspring rats on PND42 in the nano-lead group was significantly lower than that in the control group (2.28 ± 0.51 ng/g vs 3.69 ± 0.69 ng/g, P<0.05). The escape latencies of offspring rats on PND21 and PND42 in the nano-lead group were longer than those in the control group (15.54 ± 2.89 s vs 9.01 ± 4.66 s; 6.16 ± 1.42 s vs 4.26 ± 1.51 s). The numbers of platform crossings of offspring rats on PND21 and PND42 in the nano- lead group were significantly lower than those in the control group (7.77 ± 2.16 times vs 11.2 ± 1.61 times, P<0.05; 8.12 ± 1.51 times vs 13.0 ± 2.21 times, P<0.05).
ONCLUSIONn Nano-lead exposure can result in iron homeostasis disorders in the hippocampus and cortex of offspring rats and affect their learning and memory ability.

South Africa is an ethnically and culturally diverse presidential republic country. The medical and health system consists of public and private medical care. AIDS, lower respiratory infections, neonatal diseases, and interpersonal violence and road injuries are the leading causes of adult death. South Africa has rich herbal resources, and a long history of traditional medicine, which is mainly black African traditional medicine. Until the establishment of diplomatic relations between China and South Africa in 1998, the development of TCM was significantly improved, and legislation of TCM was adopted by the government in 2000. Chinese herbal medicine has not yet formed industrial standardization, the TCM application and TCM education are insufficient. Therefore, it is suggested to accelerate the standardization of TCM, to strengthen the TCM education for professional TCM practitioners, and to form a large-scale, industrial and standardized development model. Only in these ways can TCM provide good medical services for residents in South African.
