Objective To investigate the effect of pretreatment with parecoxib for postoperative analgesia in patients undergoing laparoscopic hernia repair. Methods Sixty patients undergoing laparoscopic hernia repair were assigned in two groups by random digits table with 30 cases each. The patients in pretreating group received parecoxib 40 mg intravenously before anesthesia, and in control group with the same capacity of normal saline. All patients were anesthetized with combined spinal epidural blockage and tranquilized with pethidine, droperidol and diazepam. Postoperative pain of the abdomen incision was assessed by visual analogue scale (VAS) and the pain of shoulder or back was judged by a 4 grade scale. Side-effects, supplement analgesic, passage of gas by anus 24 h after surgery were observed as well. Results The abdomen incision VAS at 4,8,12,24 h after surgery in pretreating group were lower than those in control group (P ＜ 0.05). And the incidence of pain of shoulder or back was lower in pretreating group (13.3% ,4/30) than that in control group (33.3% ,10/30)(P ＜0.05). While the cases needing supplement analgesic also decreased in pretreating group (13.3% ,4/30) compared with control group (40.0%, 12/30)(P ＜ 0.05). And the side effects and passage of gas by anus 24 h after surgery had no significant difference in two groups. Conclusion Pretreatment with parecoxib in patients undergoing laparoscopic hernia repair may relieve the postoperative incision pain and the pain of shoulder or back while reducing the analgesic supplement without side effects.

Objective To analyze the distribution of tophus in ankle and tarsal joints by multislice spiral computed tomography (MSCT)and to explore the pathogenesis of gout.Methods 34 patients with a documented diagnosis of gout underwent CT examina-tion of bilateral ankle and tarsal joints,and 55 ankle and tarsal joints were observed tophus.The sites of tophus deposition were cate-gorized into groups of ligament,tendon and joint in order to record and analyze.Results The tophus were showed at the anterior talofibular ligament (n=38),the medial ligament (the site of talus and calcaneus)(n=30)and the interosseous talocalcaneal liga-ment (n=29)(P <0.05)in the group of ligament;at achilles tendon (n= 18),followed by tibialis posterior tendon (n= 7)(P <0.05)in the group of tendon;at articulations intercuneiformes (n=1 5)and inferior tibiofibular articulation (n= 10)(P <0.05 )in the group of joint.Conclusion In ankle and tarsal joints,tophus is commonly deposited at the anterior talofibular ligament,at the achilles tendon and the articulationes intercuneiformes.

Objective To evaluate the dual blood supply of lung adenocarcinoma and squamous cell carcinoma using dualinput perfusion CT.Methods A total of 40 patients confirmed with lung cancer pathologically underwent CT perfusion (CTP) scanning.The pulmonary flow (PF),bronchial flow (BF),perfusion index (PI,PI=PF/[PF+BF])and tumor volume,location were measured and recorded by 2 experienced radiologists.The differences in CTP parameters between lung adenocarcinomas and squamous cell carcinomas,the central lung cancers and peripheral lung cancers were analyzed.The correlation between the tumor volume and CTP parameters was analyzed.Interobserver agreements were assessed with intraclass correlation coefficient (ICC).Results The average of PF,BF and PI of all 40 cases was (54.26± 21.07)ml/ (min · 100 ml),(64.41±22.06)ml/(min · 100 ml) and (43.38±16.07)％,respectively.Tumor histology was consistent with adenocarcinomas in 23 cases and squamous cell carcinomas in 17 cases,lung adenocarcinomas showed lower PI than that of squamous cell carcinomas (t=-2.196,P=0.034).There were 17 peripheral lung cancers and 23 central lung cancers,and the PI of the peripheral lung cancers was higher than that of the central lung cancer (t=2.305,P=0.027).No statistically significant differences were found for BF and PF between two types of lung cancers and central lung cancers and the peripheral cancers (all P＞0.05).Tumor volume was negatively associated with PI (r =-0.39,P=0.01).Good agreement was found between the two observers,the ICC for BF,PF and PI was 0.97,0.93 and 0.91,respectively.Conclusion Dual-input CTP technique can be used to evaluate the differences of blood supply between different pathological types and locations of lung cancer,with PI depending both on tumor size and location.

Background Recently,small incision lenticule extraction (SMILE) procedure is used to correct myopia.The clinical safety and efficiency of SMILE have been approved,but its predictability to corneal ablation depth is brought into focus.Objective This study was to compare the predictability of ablation depth in central cornea between SMILE and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia.Methods A nonrandomized controlled clinical study was performed.Two hundred and seventy eyes of 135 myopic patients who were going to receive corneal refractive surgery were included in Beijing Tongren Hospital from October 2015 to May 2016.SMILE and FS-LASIK were performed on 138 eyes of 69 patients and 132 eyes of 66 patients matched in demography respectively under the informed consent.Central corneal thickness was measured by RTVue FD-OCT before and 1 week after surgery.The refractive power,actual ablation depth (difference of central corneal thickness before and after surgery) and central corneal cutting error (difference between theoretically expected ablation depth and real ablation depth) were intergrouply compared,and the correlation of real ablation depth with theoretically expected ablation depth was assessed.Results No significant difference was found in spherical power,astigmatic power and spherical equivalent after surgery between SMILE group and FS-LASIK group (t =-1.826,-1.405,-1.420,all at P＞0.05).The actual ablation depth was (76.96± 15.27)μm in the SMILE group,which was significant lower than (96.76± 16.52) μm of theoretically expected ablation depth (t =-23.016,P ＜ 0.01);however,there was no significant difference in the FS-LASIK group between actual and expected ablation depth ([77.92 ± 18.69] μm versus [77.42± 15.60] μm) (t =-0.604,P =0.547).The central corneal cutting error was (20.55 ± 8.51) μm in the SMILE group and (7.17±5.97) μm in the FS-LASIK group,showing a significant difference between them (t=14.950,P＜0.01).The positive linear correlations were seen between actual and expected ablation depth in both SMILE group and FS-LASIK group (r=0.799,0.867,both at P＜0.01).The actual ablation depth was increased over expected ablation depth,with the regression equations of Y=3.892+0.749X in the SMILE group and Y=3.443 + 0.957X in the FS-LASIK group.Conclusions The actual corneal ablation depth is less than expected corneal ablation depth in SMILE procedure,while in FS-LASIK procedure,the actual corneal ablation depth appears to be consistent with the expected one,inferring a good predictability in corneal ablation depth in FS-LASIK surgery.

Objective To explore the effect of Erbin deficiency in MDA-453 cells on trastuzumab(Herceptin) resist-ance .Methods The specific short hairpin RNA ( shRNA) targeting Erbin was designed and cloned into plasmid pSuppres-sor, which was subsequently transfected into MDA-453 human breast cancer cells .After being selected by G418, MDA-453 cells stably expressing Erbin shRNA were obtained and nominated as MDA-453-Erbin sh.The MDA-453 cells express-ing control shRNA ( MDA-453-NC) were used as control cells .The expression of Erbin at the protein level in MDA-453-NC and MDA-453-Erbin sh cells was analyzed by Western blotting .Cell proliferation and colony formation assays were em-ployed to investigate the effect of Erbin knockdown on the sensitivity of MDA -453 cells to trastuzumab in vitro.The levels of Erbin expression in human breast cancer tissue and normal breast tissue samples were evaluated by immunohistochemistry . Results MDA-453 cells, in which Erbin expression was stably knocked-down, were established.Deficiency of Erbin in MDA-453 cells could antagonize the anti-proliferation effects of trastuzumab in vitro.The level of Erbin expression was de-creased in some breast cancer tissue samples compared with normal breast tissue samples .Conclusion Erbin deficiency may induce the resistance of breast cancer cells to trastuzumab therapy .

87%. CONCLUSIONS The surveillance of overexpressing AmpC ?-lactamases in cefoxitin-resistant Gram-negative bacillus must be enhanced.The therapy of infections caused by related bacillus should make imipenem and meropenem a chief choice.DHA-1,CMY-2 and CMY-22 AmpC enzymes are found in Fuzhou.

Skeletal muscle possesses a remarkable ability for its regeneration and injured tissue repair. This ability depends on the activity and contributions of muscle satellite cells. Proliferating satellite cells, termed myogenic precursor cells or myoblasts, are activated and driven out of their quiescent state upon muscle injury. In this summary, we present a review to summarize the molecular regulation in skeletal satellite cells to light on the satellite cells' self-renewal mechanism.

Objective To make a comparison between the plain radiograph, CT, and MR findings of gouty arthritis and to analyse the relationship between clinical data and imaging findings. Methods Fifty-four joints of 33 patients with a confirmed diagnosis of gouty arthritis were included in this study. In the morning, the blood uric acid level of patients was tested before meal. In the afternoon, their clinical data were recorded and joints were examinated by plain radiography, CT, and MRI. The imaging findings were evaluated by tophi, bone erosion, soft tissue swelling, hydrarthrosis, synovial thickness, and bone oedema. The data was analyzed by Chi-square test, indepentdent-samples t test, and logistic regression. Results The Chi-square test was utilized to evaluate number of joints with tophi(CT>plain radiography, MR>plain radiography, P<0. 01), soft tissue swelling (MR>CT>plain radiography, P<0. 01), hydrarthrosis(MR>CT, P<0. 01). In addition, 35 joints had bone oedema and 50 joints had synovial thickness. The course of disease(tophi positive group vs tophi negative group, P<0. 01) was analyzed by indepentdent-samples t test. The tophi's causative agents including bone erosion and course of disease were analysed by logistic regression(P<0. 01). Conclusions MRI is superior to CT and plain radiography on the early diagnosis of gout. Tophi and bone erosion may not affect the blood uric acid level. With the progression of disease, the probability of tophi formation increases. The relationship between the formation of tophi and bone erosion may be interpromotied.

Objective To investigate the knowledge about risk factors for stroke in stroke patients. Methods 1043 stroke patients in 10 hospitals were investigated with self-designed questionnaire. Results The rate of awareness of risk factors for stroke was: hypertension 61.55%, hyperlipidemia 40.27%, drinking 32.21%, smoking 30.11%, diabetes mellitus 28.67%, heart disease 23.11%. 6.42% knew all the 6 risk factors, and 20.13% did not know any risk factor. The rate of awareness of diabetes mellitus was different among various aged groups (P<0.01), and the rate of awareness of hypertension, hyperlipidemia, and diabetes mellitus increased with the years of education. Conclusion The stroke patients know less about the common risk factors for stroke, who need more health education.
