Chinese Journal of Perinatal Medicine 1998;0(03):-
Objective To test whether IL 6 has any harmful effects on developing brain in neonatal rats, and try to illustrate its probable pathogenesis. Methods The neonatal rats were injected with different doses of rhIL 6 intravenously or intraventricularly. Animals were killed at 24 or 48 hours after injection to observe the pathological changes of brain tissues. Results Among animals killed at 24 hours after the intravenous injection with 1 000 U or 5 000 U rhIL 6, perivascular edema and ischaemic changes of neurons appear in their brain. There is no difference in the pathological changes in the brain of the rats treated with different doses. 72 hours after the intravenous injection, edema is still obvious, and ischaemic cell change in neurons aggravates into homogenizing cell change. When the brains are examined at 24 hours after intraventricular injection with 1 000 U rhIL 6, the pathological changes are the same as those treated by intravenous injection. Subarachnoid hemorrhage occurs more frequently in animals examined at 24 hours after 5 000 U rhIL 6 intraventricular injection than in those with intravenous injection. Besides, there appears local demyelination in the brain examined at 72 hours after the intraventricular injection of 5 000 u rhIL 6. Conclusion IL 6 by intravenous injection and intraventricular injection has harmful effects on the brain of neonatal rats.

Objective To evaluate prognostic value of electroencephalogram (EEG) in neonatal with hypoxic ischemic encephalopathy (HIE). Methods Sixty two infants with HIE was studied by doing physical examination, intelligence test, CT and EEG. Their clinical outcome was compared to their EEG in the first month after birth. Results Incidence of sequelae in normal or mild abnormal EEG and severe abnormal EEG were 3%, 29%, respectively. Among three infants of EEG cases, two dead and one developed cerebral palsy infant. Among four of burst suppression found in the EEGs, two cases dead, one developed cerebral palsy, one was normal. In five of hypoactive EEG, one dead, one developed cerebral palsy, and the other was with low IQ. Conlusion The prognosis is related to the background activity of EEG. The presence of a burst suppression EEG pattern and a hypoactive/flat EEG are negative prognostic criteria.

Objective To evaluate the efficacy and safety of low?level laser therapy(LLLT)for androgenetic alopecia, and to compare the therapeutic effect of LLLT alone versus in combination with finasteride tablets. Methods Thirty?nine male patients were randomly divided into the LLLT group(n=21)and combination group(n=18)to be treated with LLLT alone or in combination with oral finasteride tablets(1 mg/d)for 6 months. LLLT was given twice a week, and each session lasted 30 minutes. All the patients were photographed and asked to fill a questionnaire about subjective symptoms, and hair density (the number of hairs per unit area on the scalp) was determined by using a dermatoscope to evaluate the grade of alopecia, before the treatment, and 3 and 6 months after the treatment. Results The hair density in the LLLT group was significantly higher after 6 months than after 3 months of treatment and before the treatment(184.59 ± 21.17 vs. 169.24 ± 29.21 and 166.67 ± 32.94 hairs/cm2, both P<0.05), but was insignificantly different between before and after 3 months of treatment (P > 0.05). The hair density in the combination group significantly increased after 6 and 3 months of treatment compared with that before the treatment(201.80 ± 16.55 and 186.39 ± 17.97 vs. 157.85 ± 27.97 hairs/cm2, both P < 0.05), and was significantly higher after 6 months than after 3 months of treatment(P<0.05). No significant difference was observed in hair density between the two groups before the treatment(P>0.05), but the combination group showed increased hair density compared with the LLLT group after 3 and 6 months of treatment(both P<0.05). After 6 months of treatment, LLLT alone was effective in 17 patients, but ineffective in 4 patients, and the combination therapy was effective in 16 patients, but ineffective in 2 patients, with no significant difference in the response rate between the LLLT group and combination group (χ2 = 0.057, P > 0.05). During the treatment, 24(62%)patients felt less greasy, and 22(56%)reported less hair loss, with no discomforts reported by the patients except local warm feeling. Conclusion LLLT is indeed effective for the treatment of androgenetic alopecia with no adverse reactions.

Objective To explore the relationship between H.pylori (HP) infection and the functional dyspepsia (FD) by 4-lead electrogastrography (EGG). Methods The data of the gastric electrical activity of 163 children with FD, includ-ing 103 children with HP infection (group A), 60 without HP infection (group B) and 22 healthy controls (group C) were mea-sured by 4-lead EGG, which included normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria per-centage (T%) and motilin uneven rhythm percentage (A%). EGG frequency and power examination included the main fre-quency (DF), the main power (DP) and postprandial/pre-prandial gastric electrical main power ratio (P/R). EGG data was compared between three groups. Results There was significant difference in pre-prandial and postprandial percentage of different slow wave frequency between group A and group B. There were no significant differences in pre-prandial and post-prandial changes of DF and DP between group A and group B. There was no significant difference in the pre-prandial and postprandial percentage change of different slow wave frequencies in 84 HP negative patients. But the significant change was found in pre-prandial and postprandial change of DF, DP and P/R. Conclusion The eradication of HP improved the gas-tric electrical activity and relieved the postprandial symptom in children with functional dyspepsia under HP infection.

Objective To compare the biological characteristics of Culex pipiens pallens between permethrin-resistant strain and the susceptible strain. Methods In laboratory, the biological characteristics about bloodsucking, reproduction and development of permethrin-resistant and susceptible strains were observed and recorded. Life table of the experimental populations was constituted. Results The bloodsucking rate of resistant strain was lower than susceptible strain and the difference was significant. The life-span of adults of resistant strain and the developmental duration of eggs, larvae and pupae were longer than susceptible strain and the difference was significant. The death rate of eggs of resistant strain was higher than that of susceptible strain and the difference was significant. The permethrin-resistant strain showed a fitness value of 0 ^58 relative to the susceptible strain. Conclusion The permethrin resistance of Culex pipiens pallens may result in a disadvantage to its reproduction and development.

Objective:To explore the impact of clinical pharmacists involved in the treatment team on the reasonable drug use rate in medical orders. Methods:Totally 782 medical records including hypertension and 1-3 kinds of hypertension associated diseases in our hospital from January 2011 to December 2011 were used as the pre-intervention group, and 1 061 ones with the same conditions from September 2012 to August 2013 were used as the post-intervention group. The patients of the two groups were divided into 8 dis-ease subgroups, clinical pharmacists performed timely intervention on the medical orders in the post-intervention group, and the rational drug use rate between the two groups was compared. Results:In hypertension, hypertension associated coronary heart disease, hyper-tension with heart failure and hypertension with diabetes subgroups,the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 01), in hypertension with coronary heart disease and heart failure, hypertension associ-ated coronary heart disease and diabetes, hypertension with heart failure and diabetes subgroup, the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 05), while in hypertension with coronary heart disease, heart failure and diabetes subgroups, the difference was not statistically significant(P>0. 05). After the medical records in the 8 sub-groups were aggregated, the difference in the rational drug use proportion before and after the intervention was statistically significant( P<0. 01). Conclusion:Clinical pharmacists should involve in the clinical treatment to intervene irrational drug use,which can signifi-cantly improve the medical record rationality, avoid the health risks as much as possible and ensure the medication safety and treatment effectiveness for patients.

Objective To assess the relationships between bile reflux gastritis (BRG) and Helicobacter pylori infec-tion in children. Methods A total of 258 BRG cases were included in BRG group and 1 749 gastric mucosal inflammation cases without bile reflux were used as control group. Children with BRG were divided into three groups according to the dis-ease classification and they were also sub-divided into three groups according to the bile reflux indexing. The infection rates of Helicobacter pylori were analyzed in different groups. Results Compared to control group (34.02%), the infection rate of Helicobacter pylori was significantly higher in BRG group (46.12%). The infection rates of Helicobacter pylori infection were 40.86%(38/93), 45.53%(56/123) and 59.52%(25/42) in patients with mild, moderate and severe infections. There was no significant difference between them (χ2=4.089, P>0.05). The positive rates of Helicobacter pylori infection were 37.32%(53/142), 53.68%(51/95) and 71.43%(15/21) in children withⅠ,ⅡandⅢreflux indexing, and there was significant differ-ence between them (χ2=12.022,P<0.01). Conclusion Helicobacter pylori infection is one of the causative factors leading to BRG in children. The bile regurgitation increased with the increasing of Helicobacter pylori infection.
