AIM:To explore the differences between unilateral recess-resection (R & R) and bilateral lateral rectus recession (BLR-rec) in the treatment of basic intermittent exotropia.METHODS: A retrospective analysis of treatment of basic intermittent exotropia in 89 patients,in which 49 cases underwent unilateral recess-resection,40 cases underwent bilateral lateral rectus recession of external rectus retroperitoneal surgery January 2013 to January 2015 in our hospital.The stereopsis and strabismus were observed in 1d,1,6mo,1 and 2a after operation.RESULTS: There was no significant difference in the success rate and oblique degree between the two groups after 1d,1,6mo,1 and 2a (all P>0.05),but the success rate of the operation was reducing as time passed.After 2d of the operation,the drift of the R & R group was 12.10±5.74PD and the drift of the BLR-rec group was 7.78±4.21PD,the difference was statistically significant (P=0.021).The R & R group was more likely to cause lateral slanting than BLR-rec group.Two groups of patients with nearly stereopsis were both significantly improved,there was no significant difference between the two groups in the two groups (x2=4.530,P=0.210).CONCLUSION: The long-term stability of BLR-rec is superior to R & R.

Objective To study the clinical significance of pulmonary membrane diffusing capacity(Dm) and pulmonary capillary blood volume(Vc) in patients with stable chronic obstructive pulmonary disease(COPD). Methods Spirometry was performed in 38 patients with stable COPD and 35 healthy individuals in resting condition.The changes of pulmonary parameters were obtained and compared between groups. Results Spirometry test revealed that the percent predicted forced expired volume in one second(FEV1),FEV1/forced volume capacity(FVC)and the percent predicted maximal ventilatory volume(MVV) were declined from stage Ⅰin patients with COPD in comparison with healthy individuals,while diffusing capacity for carbon monoxide of lung(DLCO),carbon monoxide diffusing capacity per liter of alveolar(DLCO/VA),Dm and Vc were declined from stage Ⅱ.Dm in patients with COPD of stageⅠwas sig-nificantly decreased compared with the controls,while Vc was increased compared with the controls(both P

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

Objective To evaluate MRI in the diagnosis of the bone contusion of the knee joint and its clinical significance.Methods Using special coil for knee joint,coronal,sagittal,axial and oblique sagittal plane scanning with fast spin-echo sequence(T_1WI,T_2WI,PDWI+FS)was performed on knee joint in 205 patients in three days after injury.According the distributing bone marrow edema and injury mechanism,bone contusion were classified five types as pivot shift injury,clip injury,dashboard injury, hyperextension injury and lateral patellar dislocation.Results One hundred and forty-five cases of the 205 patients were found bone marrow edema without fracture on X-ray films.Among them,pivot shift injury was found in 43 cases accompanied with anterior cruciate ligament rupture in 30 cases,tear of the posterior horn of the lateral or medial meniscus in 12 and tears of the medial collateral ligament in 8 cases;clip injury in 53 cases accompanied with anterior cruciate ligament rupture in 10 cases,tear of the posterior horn of the lateral or medial meniscus in 15 and tears of the medial collateral ligament in 38 cases;dashboard injury 40 cases accompanied with posterior cruciate ligament rupture in 16 cases,hyperextension injury 9 cases accompanied with anterior cruciate ligament rupture in 2 cases,posterior cruciate ligament rupture in 5 cases.No lateral patellar dislocation was found.Forty-eight of 145 patients had undergone arthroscopy, 43 cases(89.6%)of them were in accordance with MRI diagnosis.Bone contusion were defined as geographic regions of abnormal signal intensity,that is,low signal intensity in T_1-weighted images and high signal intensity in PD-weighted or T_2-weigeted images with fat saturation.Conclusion MRI can accurately display the location and area of bone contusion of the knee joint as well as its adjunctive structure injury and deduce their injury mechanism.MRI should be used routinely for knee trauma.

The basic medicine teaching must meet the clinical application,while the clinical practice should be timely feedback to basic medical teaching,which is the embodiment of the idea in the translational medicine.The experimental teaching is an important part of modern pathology teaching.We actively improve the experiment course and deepen the basic concept of translational medicine in the medical education development by adopting such approaches as using the problem-based learning method(PBL) to promote the link between basic courses and clinical pathology,integrating and optimizing the teaching content to promote the knowledge mastery and conducting molecular pathology research to promote the implementation of translational medicine.

Objective:To observe the therapeutic effect of the treatment with intravenous(Ⅳ)ibandronate com- bined with chemotherapy on patients with skeletal metastases.Method:138 patients with skeletal metastases were randomly divided into ibandronate group combined with chemotherapy(68 cases)and simple chemotherapy group(70 cases).The controlled group took a standard chemotherapy project but combined the treatment group took a chemotherapy project plus ibandronate.In a week after the chemotherapy,68 cases of the treatment group were treated with ibandronate 4mg in NS 500ml by intravenous infusion once 4 weeks for 3 months.The effect was evaluated when the three cycles finished.Result: There was a statistical difference(P

To investigate the bioactivity of Nocardia rubra Cell (NC), the mice were used to assay the toxicity, the effects on immune organs, phagocytes of peritoneal macrophage and the antitumor activity by perfusion of NC to the stomach of mice. Results indicated that NC could obviously stimulate in vitro the phagocytosis of peritoneal macrophage from mice, and remarkably inhibit the growth of S180 in mice, and its LD50 was more than 10 g/kg. In conclusion, NC had low toxicity, it could significantly enhance the organism immunologic function and had obvious antitumor effect and the anti-infection effect against a pathogenic microorganism.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efficacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted.

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.
