OBJECTIVE：To study the improvement ef fects of sanggenone C on lipid accumulation in human liver cancer HepG2 cells induced by free fatty acid （FFA）. METHODS ：HepG2 cells were divided into control group ，model group ， fenofibrate group （10 μmol/L），sangerone C low ，medium and high concentration groups （2，4，8 μmol/L）. Except for control group，other groups were treated with 1 mmol/L FFA to induce lipid accumulation model ，and administration groups were cultured with relevant medium containing drugs. The lipid accumulation was observed by oil red O staining ，and lipid level and triglyceride （TG） content were also determined. Real-time PCR and Western blot assay were adopted to detect the mRNA and protein expression of PPARα，CPT-1，SREBP-1c，FAS，SIRT1 and PGC- 1α in HepG2 cells. RESULTS ：Compared with control group ， the nucleus was atrophied significantly and the volume became smaller ，and the number of lipid droplets was significantly increased；the level of lipid ，TG content ，mRNA and protein expression of SREBP- 1c and FAS were significantly increased （P＜ 0.05 or P＜0.01），mRNA and protein expression of PPARα，CPT-1，SIRT1 and PGC- 1α were decreased significantly（P＜0.01）. Compared with model group ，no obvious nucleus atrophy and normal volume were observed in sangerone C groups ，and the number of lipid droplets was significantly reduced ；the levels of lipid ，TG content ，mRNA and protein expression of PPARα pathway related genes （except for SREBP- 1c protein in saggenone C low concentration group ）were significantly reversed （P＜ 0.05 or P＜0.01）. CONCLUSIONS ：Sangenone C can significantly improve the lipid accumulation of HepG 2 cells，and its mechanism may associated with regulating PPAR α signaling pathway，improving cell lipid oxidation ability and inhibiting lipid synthesis.

Objective:To investigate the serotype distribution and drug resistance of Streptococcus pneumoniae ( S. pneumoniae) isolated in Urumqi Children′s Hospital and to evaluate the significances of 13-valent pneumococcal conjugate vaccine (PCV13) in preventing infection and controlling drug resistance. Methods:The S. pneumoniae isolates stored in clinical laboratory of Urumqi Children′s Hospital from January to December in 2018 were re-cultured.The serotypes were detected by capsule swelling experiment to assess the coverage rate of PCV13.The minimum inhibitory concentration (MIC) of Penicillin, Amoxicillin, Cefotaxime and Ceftriaxone were detected by E-test method, and the susceptibility of the isolates to Meropenem and other 9 antibiotics was detected by VITEC 2 Compact system. Results:A total of 225 S. pneumoniae strains were identified.The common serotypes were 19F (32.9%), 23F (12.0%), 19A (10.7%), 6B (10.2%) and 6A (8.0%). PCV13 coverage rate was 80.4%.There was no significant difference in serotype distribution and PCV13 coverage between children < 2 years old and ≥ 2 years old, as well as between Han and minority people.The 57.8% and 31.7% strains showed intermediate susceptibility and resistance against oral Penicillin, respectively.Based on the breakpoints for meningitis, 89.4% strains were resistant against pare-nteral Penicillin, and 47.5% and 64.6% strains were non-susceptible (mainly intermediately susceptible) to Ceftria-xone and Cefotaxime, respectively.The resistance rates of strains against Erythromycin, Sulfamethoxazole-trimethoprim and Tetracycline were as high as 98.1%, 67.6% and 89.6%, respectively.More than 90% tested isolates were susceptible to Amoxicillin, Meropenem, Levofloxacin or Moxifloxacin.PCV13 strains were more resistant to Penicillin than non-PCV13 strains. Conclusions:The serotypes 19F, 23F, 19A, 6B and 6A are common among the S. pneumoniae isolated in Urumqi.The coverage rate of PCV13 is about 80%.There was no significant difference in serotype distribution between Han and minority nationality children. S. pneumoniae were frequently resistant against Erythromycin.The high resistance to Penicillin and other beta-lactams should be taken into account when treatment is decided for suspected pneumococcal meningitis.Universal administration of PCV13 would be effective strategy to prevent pneumococcal infection in children and to control the drug resistance of S. pneumoniae.

Objective To study the influence of aerobic exercise and relaxation therapy on quality of life and symptoms of breast cancer patients undergoing chemotherapy.Methods A total of 116 female breast cancer patients in our hospital were divided into study group and control group by random number table.The control group took routine nursing intervention,and the study group applied aerobic exercise and relaxation therapy on the basis of the control group.And the symptoms,quality of life and emotions before and after intervention were compared.Results After intervention,the psychological symptoms,hormone related symptoms,the digestive system symptoms and self-image disorder symptoms scores in the study group were lower than that in the control group (P ＜ 0.05),the physiological status,functional status,emotion,social/family conditions and additional attention scores were higher than that in the control group (P ＜ 0.05).Conclusion Aerobic exercise and relaxation therapy for patients with breast cancer chemotherapy has a significant effect,and it can effectively improve the quality of life and symptoms,so it is suitable for clinical promotion.

OBJECTIVE To evaluate the reason and protection measures of occupational exposure.METHODS From Jan 2005-Mar 2008,all medical personnel in our hospital were investigated by face to face investigation and checking recording data.The causes,modalities,management and prophylaxis of occupational exposure were analyzed.RESULTS Seventy-six person suffered occupational exposure,including 51 nurses(67.11%),18 doctors(23.68%) and the other 7 workers.Occupational exposure mainly occurred in 20-30 years old medical workers.61 persons(80.26%) suffered stab injury and sharp instrument injury.All 76 front medical personnel could make appropriate management after occupational exposure and without further infection.CONCLUSIONS Some first front medical personnel do not recognize the hazard of the occupational exposure.It′s necessary to enhance the management and training and to establish a corresponding standard to protect medical personnel from being harmed by occupational exposure.

Objective To assess the value of prenatal sonographic diagnosis on fetal agenesis of corpus callosum(ACC). Methods A retrospective study was on prenatal sonographic findings of 10 cases with ACC malformation and their abnormalities in central nervous system (CNS) or extra-CNS.Results The special sonographic findings established the diagnosis of ACC malformation in all 10 cases,with 7cases diagnosed absence agenesis. Among all patients with ACC,6 cases were accompanied with abnormalities in extra-CNS,8 in CNS and 5 in both. Conclusions Prenatal ultrasonography plays a vital role in accurate diagnosis on fetal ACC. Attentions should be paid to the indirect encephalic features and complicated abnormalities so as to make accurate and prompt diagnosis.

Objective To assess the value of prenatal ultrasonography on fetal forearm and crus malformations by studying the ultrasonographic characteristic in relation to methods of examination. Methods All fetus were evaluated by using a systematic continuous sequence approach (SCSA) with ultrasonography. A close attention was paid on shapes, structures and movement of fetal forearm and crus, and fetus specimens after induced labor were rescanned by ultrasonography under the condition of mimic intra-uterus. Results Thirty of 33 cases (90.9%) with fetal forearm and crus malformations (totally 48 of 54 limb anormalies, 88.9%) were correctly diagnosed by prenatal ultrasonography. Six limb malformations of 3 cases were missed. Conclusion Our study demonstrates that the malformations of forearm and crus detected with prenatal ultrasonography are highly accordant with the malformations revealed in fetus in vitro. It is important to abide by the SCSA in ultrasonographic diagnosis of fetal forearm and crus malformation.

Objective To investigate prenatal ultrasound diagnosis of radial ray abnormalities and its clinical value. Methods All the fetus that entered usual prenatal ultrasound diagnosis were scanned each limb using a systematic continuous sequence approach (SCSA) with Acuson Sequoia 512 and GE Logiq 400 equipments. All the artificial aborted fetal radius malformation also had ultrasound examination in a simulating intrauterine estate and /or X-ray examination. Results Correctly diagnosis was made in 13 cases fetal radial ray abnormalities by prenatal ultrasonography following SCSA through the scaning course. All the fetal radial ray abnormalities had radius absence(only one skeleton in the forearm) or radius dysplasia and characteristic radial club hand. Ray abnormalities can be classifyied into three types on ultrasonography: type Ⅰ, radius absence; type Ⅱ,radius part absence; type Ⅲ,radius dysplasia.Conclusions Mastering characteristic radial club hand and SCSA are the keys to diagnose fetal radial ray abnormalities by prenatal ultrasonography.
