Objective To evaluate Zeus robot-assisted laparoscopic cholecystectomy. Methods Forty patients were divided into two groups receiving respectively Zeus robot-assisted laparoscopic cholecystectomy (group A, 20 cases), and laparoscopic cholecystectomy (group B, 20 cases). A variety of clinical parameters were evaluated. Compared between these two groups. Results Camera clearing (1.1?1.0) times and time used for operation field adjustment in group A (2.2?0.7) min were significantly less than those in group B (4.5?1.5,7.5?1.2) min. Dissection actions(337?86)times and operative errors(10%) in group A were less than those in group B(389?94) times,25%. The operation time(104.9?20.5) min and setup time (29.5?9.8) min in group A were longer than those in group B (78.6?17.1) min,(12.6?2.5) min. The blood loss,and postoperative hospital stay were similar. There were no postoperative complications in either groups, and conversion to open surgery was done in one each patients. Conclusions Compared with laparoscopic technique, Zeus robotic surgical system offers greater ability of controlling operation field, precise and stable operative manipulations though it requires longer operation time.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

OBJECTIVETo evaluate mid-term clinical results of microendoscopic discectomy (MED) for the treatment of lumbar disc hermiation.

METHODSIn the study, 117 patients were reviewed,including 63 male and 54 female, ranging in age from 24 to 72 years,with an average of 50.6 years. Among the patients, 60 patients had simple lumbar disc herniation, 10 patients had simple lateral crypt stenosis, 32 patients had lumbar disc herniation combined with lateral crypt stenosis, and 15 patients were combined with calcified nucleus pulposus. Two patients had herniation in L3-L4, 56 patients in L4-L5, 48 patients in L5-S1, 11 patients in L4-L5 and L5-S1. The central type of lumbar disc herniation occurred in 22 patients and the lateral type of herniation occurred in other 95 patients. The Protrusion type of herniation occurred in 32 discs, ruptured type in 73 discs, and free type in 12 discs. Ninety-eight patients had lumbar and leg pain in one side, and 19 patients in double sides. MED was used to remove the nucleus and decompress the nerve root canal.

RESULTSAll the patients were followed up and the duration ranged from 48 to 84 months,with an average of 5.5 years. According to lumbar and leg pain evaluation criteria from spinal group of Chinese Orthopaedic Association, there were 93 patients got an excellent result, 16 good and 8 poor.

CONCLUSIONAppropriate control indications and skillful surgical techniques are the key points to decrease the complication and to improve the curative effect.

OBJECTIVETo investigate the expression of CD123 and its significance in lymphocytic leukemia.

METHODSCD123 expression in 139 lymphocytic leukemia patients and in lymphocytes from 10 normal bone marrows (BM) was analyzed by multi-parameter flow cytometry. Cytogenetic and minimal residual disease (MRD) analysis were performed in acute B-lymphocytic leukemia (B-ALL) patients.

RESULTSCD123 expression was absent in B lymphoid lineage stem-progenitor cells, mature B and T lymphocytes from 10 normal BM. Among 139 lymphocytic leukemia patients, CD123 was negative in 5 T-ALL and 23 B-CLL patients. However, among 111 B-ALL patients, CD123 was expressed in 106 (12 pro B-ALL, 57 common B-ALL and 37 Pre B-ALL) (95.49%) but not in 5 mature B-ALL patients. There was a positive correlation between CD123 and p-Akt expression, and CD123 expression was much higher in hyperdiploid than in non-hyperdiploid B-ALL patients. A statistically significant difference in relapse rate within 12 months (MRD positive group: 63.04% vs MRD negative group 21.56%)and in disease free survival (DFS) time was found beween patients with MRD\[(36.06 +/- 2.62)%\] or not \[(48.23 +/- 1.82)%\] (P < 0.01). Moreover, stable CD123 expression could be observed in B-ALL patients in relapse.

CONCLUSIONSCD123 was predominantly expressed in B-ALL patients and remained in patients in relapsec, indicating that it may be an useful MRD marker in B-ALL patients.

Objective To discuss the personality characteristics and blood lipid levels in patients with infertility and depression,and further analyze the relationship between the degree of depression and the two aspects.Methods We selected 190 infertility patients and they were tested with Self-Rating Depression Scale(SDS) in Tangshan Maternal and Child Health Care Hospital Affiliated to North China University of Science and Technology from December,2015 to December,2016.All the patients were allocated into depression group (with depression symptom) and non-depression group (without depression symptom).Blood lipid levels,including triglycerides (TG),total cholesterol(TC),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were determined and the Eysenck Personality Questionnaire(EPQ) was applied to evaluate the personality traits in both groups.Results The patients in the depression group were mainly mild-to-moderate depression accouting for 64.4％,and patients with moderate to severe depression accouted for approximately 30.0％.The levels of TG and TC of patients in the depression group were significantly higher than those in the non-depression group(P＜0.01).The scores of neuroticism(N),validity scale(L) and psychoticism(P) of patients in the depression group were significantly higher than those in the non-depression group,while there was no significant difference in exextraversion (E) between the two groups.TG,E dimension,P dimension and L dimension were effective predictors of depression in infertile patients,and the Beta coefficient were 0.199,-0.240,0.424 and 0.220.Pearson partial correlation analysis showed that TG was positively correlated with P,N and L dimensions.Conclusion Infertility patients with depression may have dyslipidemia and personality changes.The degree of depression is positively correlated to the level of TG and the score of P and N.

PURPOSETo investigate efficacy of open reduction and internal fixation with the miniplate and hollow screw in the treatment of Lisfranc injury.

METHODSTen cases of Lisfranc injury treated by open reduction, miniplate and hollow screw in our hospital were retrospectively analyzed. There were 6 males and 4 females with age ranging from 25 to 45 years (mean 32 years). Among them, one case was classified as Type A, six Type B and three Type C. Injury mechanism included road traffic accidents (3 cases), fall from height (5 cases) and hit by heavy object (2 cases). All injuries were closed without cerebral trauma or other complicated injuries. The time interval between injury and operation was 6-10 days (average 6.6 days). Postoperatively, the foot function was assessed using Visual Analogue Scales (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) Scales. Healing time and complications were observed.

RESULTSAll patients were followed up for 18-24 months (average 20 months). Anatomic reduction was achieved in all patients on images. There was statistical significance between preoperative score (7.89 ± 0.34) and score at postoperative 8 weeks (0.67 ± 0.13). According to the AOFAS score, 5 cases were defined as excellent, 3 cases as good and 2 cases as fair. During follow-up, there was no wound infection or complications except for osteoarthritis in 2 cases. Healing time ranged from 3 to 6 months with an average of 3.6 months.

CONCLUSIONAnatomical reduction of Lisfranc injury can be achieved by open reduction and internal fixation with the miniplate and hollow screw. Normal structure of Lisfranc joint is regained to a great extent; injured ligaments were also repaired. Therefore, this method offers excellent curative effect and can avoid postoperative complications and improve the patients' quality of life.
