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.

0.05). Conclusion LCP enrichment formula is suitable to premature infants. Its lipid composition is more close to that of breast milk and benefit to the brain and retina development of premature infants.

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 observe the effect of Liu's massage technique on teenagers with cervical vertebra disease.Methods 65 teenagers with cervical vertebra disease were divided into the trial group (n=35) and control group (n=30) treated with routine physical therapy and cervical vertebra disease gymnastics, but cases in the trial group were added with treatment of Liu's massage technique. All cases of two groups were evaluated with Clinical Assessment Scale for Cervical Spondylosis (CASCS) before and after treatment.Results After treatment, the CASCS scores of all cases improved significantly ( P<0.01), but the effect of the trial group was significantly superior to that of the control group ( P<0.01).Conclusion Liu's massage technique is effective on cervical vertebra disease of teenagers.

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 investigate the relationship between serum prolactin(PRL) level and neonatal seizures and to evaluate the clinical significance of PRL as a neonatal seizures marker to diagnose neonatal seizures. Methods Thirty five newborn infants with acute encephalopathy were divided into two groups: the ictal group included infants with typical clinical symptom and/or electrographic seizures and the nonictal group are those without electrographic seizures or clinical behaviors. The control group included 17 newborns. Serum PRL levels were determinded by immulite assay system at 15～30 min postictally; 2 h postictally and 2～4 days after the end of seizures. Results In the ictal group, serum PRL levels were significantly higher at 15～30 min[(302.6?93.5) ?g/L] than that of 2 h [(128.1?71.4) ?g/L], nonictal[(101.2?31.4)?g/L and (89.9?36.2) ?g/L] and control group[(73.3?20.7) ?g/L and (68.6?29.5)?g/L], P

Objective To explore the clinical efficacy of posterior component separation (PCS) with Sublay mesh repair for complex abdominal incisional hernia.Methods The retrospective cross-sectional study was conducted.The clinical data of 30 patients with complex abdominal incisional hernia who were admitted to the Beijing Chao-Yang Hospital of Capital Medical University from July 2016 to March 2017 were collected.Patients intraoperatively received PCS with Sublay mesh repair.Observation indicators:(1) intra-and post-operative situations:defect area of incisional hernia,operation time,volume of intraoperative blood loss,time of postoperative drainage-tube removal,postoperative complications and duration of postoperative hospital stay;(2) follow-up situation.Follow-up using outpatient examination and telephone interview was performed to detect recurrence of hernia and mesh-related complications up to July 2017.Outpatient examination was done once at postoperative month 1,3 and 6 and telephone interview was done at 1 year postoperatively.Measurement data with normal distribution were represented as x±s and measurement data with skewed distribution were described as M (range).Results (1) Intra-and post-operative situations:30 patients received successful PCS with Sublay mesh repair for complex abdominal incisional hernia.Defect area of incisional hernia,operation time,volume of intraoperative blood loss and time of postoperative drainage tube removal were respectively (222± 124)cm2,100 minutes (range,40-235 minutes),80 mL (range,50-200 mL) and 5 days (range,2-15 days).Of 7 patients with postoperative complications,3 were complicated with shallow surgical site infection,including 1 with wound healing by vacuum sealing drainage and 2 with delayed healing by debridement and drainage;2 with postoperative seroma were improved by aspiration and local pressurization after 1 months;1 with fat liquefaction of abdominal incision was improved by symptomatic treatment;1 with postoperative active hemorrhage was confirmed with arteriolar hemorrhage of muscular layer and then received hemostasis by ligation.Time of postoperative hospital stay of 30 patients was 15 days (range,10-57 days).(2) Follow-up situation:30 patients were followed up for (7± 3) months,without occurrences of hernia recurrence,intestinal fistula and mesh-related complications.Conclusion PCS with Sublay mesh repair for complex abdominal incisional hernia is safe and feasible,with good clinical efficacies.

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 study gastroscopic features and clinical diagnosis of prepyloric mem-brane. Methods Clinical characteristics,gastroscopic manifestation and operational findings of 18 pa-tients,whose prepyloric membrane have been confirmed by operations,were retrospectively reviewed. Results Gastroscopie findings showed that all the 1 8 patients suffered gastric retention and pyloric obstruc-tion to some degree,with 4 cases of esophageal erosion and/or esophageal ulcer,five cases of erosive hemor-rhagic gastritis,one case of ulcer at gastric antrum,gastric comer and pylorus respectively. There were 2 ca-ses of aperture like narrowing in prepyloric region. And there were 9 cases that showed obvious congestion and edema in the prepyloric mucus,with uniform circular mucusal protrusion around the stenosing stoma,and volcano-like depression in the middle,three cases of which showed mucosal membrane standing out to the gastric cavity. The membrane found in the above 11 cases located in pyloric exit or tube,and they under-went membrane excision and py|oroplasty. The other 7 cases showed thick mucosal folds at the distal antrum with radial arrangement. Round or irregular stenosing stoma were observed. These cases proved to be antral membrane,1-3 cm away from the duodenum and pylorus,and underwent simple membrane resection. Conclusion Congenital prepyloric membrane is rare and it likely mis-diagnosed. The onset and the degree of symptoms depend on the diameter of aperture of the membrane. Early endoscopy,in addition to barium contrast,should be performed on those children who have intermittent bilious vomiting,where false-positive radiological findings can be avoided,therefore,to facilitate right diagnosis and appropriate operation.
