Objective To evaluate application feasibility of Array CGH in genetic diagnosis of clinical complex chromosomal abnormalities.Methods Two patients of genetic counseling and two patients of prenatal diagnosis were selected from Xiamen Maternity & Child Health Care Hospital during the period of December 2010 to December 2011.Under aseptic conditions 2-4 ml peripheral blood was collected in EDTA and 2-3 ml Cord Blood was collected through cordocentesis after genetic counseling and preoperative examination.G-banded chromosome analysis and genome DNA extraction were carried out on the four cases.The whole genome of four cases were scanned and analyzed by Array CGH.The results of Array CGH were confirmed by FISH.Results Array CGH detected different kinds of duplications and deletions in several chromosomes.Most of these duplications and deletions were not detected by karyotype analysis.The results of Array CGH showed duplication of 4p16.3-4p15.31,deletion of 4p16.3 in the first case,duplication of Xp11.22-Xq11.1 in the second case,duplication of 4p16.3-4p15.32,deletion of 2q37.3 in the third case and duplication of 2q21.2-2q32.1,deletion of 2q14.3-2q21.1 in the fourth case.These duplications and deletions were confirmed by FISH.Conclusions Compared with conventional cytogenetic analysis,Array CGH can not only accurately detect micro deletion and micro duplication with high resolution and sensitivity but also identify breakpoints precisely.Array CGH can provide the basis for clinical genetic diagnosis.

OBJECTIVETo compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.
METHODSFrom January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).
RESULTSThere was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.
CONCLUSIONLR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.

Objective:To analyze the cardiac dosimetry of lymph node irradiation in the internal breast region after left-sided breast cancer surgery and to assess its impact on patients' quality of life.Methods:The clinical data of 108 patients who underwent inverse intensity modulated radiotherapy (IMRT) after left-sided breast cancer surgery in Cancer Hospital of Nantong University from May 2019 to May 2021 were collected and retrospectively analyzed, and divided into a study group (with internal breast, 55 cases) and a control group (without internal breast, 53 cases) according to whether the postoperative radiotherapy included lymph node irradiation in the internal breast region. The dosimetric indexes of planned target area (PTV) , cardiac tolerance, serum myocardial injury markers and quality of life before and after radiotherapy were compared between the two groups.Results:In terms of PTV dosimetry, the conformality index (CI) of the study group and the control group were 0.73±0.07 and 0.75±0.08, the homogeneity index (HI) were 0.17±0.03 and 0.17±0.02, the D max were (55.69±1.02) Gy and (55.46±1.13) Gy, the D mean were (50.54±0.23) Gy and (50.48±0.21) Gy respectively, there were no statistically significant differences ( t=1.38, P=0.169; t<0.01, P>0.999; t=1.11, P=0.269; t=1.41, P=0.160) . In terms of cardiac receptivity, the D mean of the two groups were (5.93 ± 0.32) Gy, (5.64 ± 0.30) Gy, V 40 were (0.47 ± 0.10) %, (0.41 ± 0.11) %, and V 30 were (2.48 ± 0.51) %, (2.06 ± 0.49) % respectively, and there were statistically significant differences ( t=4.86, P<0.001; t=2.97, P=0.004; t=4.36, P<0.001) . The levels of serum troponin Ⅰ (cTnⅠ) before radiotherapy in the study group and the control group were (0.09±0.02) ng/ml and (0.09±0.01) ng/ml, creatine kinase isoenzyme MB (CK-MB) were (0.27±0.08) U/L and (0.25±0.08) U/L, myoglobin (MYo) were (3.84±1.02) μg/L and (3.69±0.97) μg/L, and brain natriuretic peptide (BNP) were (172.35±16.24) pg/ml and (169.81±15.93) pg/ml respectively, there were no statistically significant differences ( t<0.01, P>0.999; t=1.30, P=0.197; t=0.78, P=0.436; t=0.82, P=0.414) . One month after radiotherapy, the levels of serum cTnⅠ in the two groups were (0.09±0.03) ng/ml and (0.09±0.02) ng/ml, CK-MB were (0.29±0.09) U/L and (0.28±0.08) U/L, MYo were (4.06±1.08) μg/L and (4.01±1.03) μg/L, and BNP were (175.13±17.09) pg/ml, (172.47±16.28) pg/ml respectively, there were no statistically significant differences ( t<0.01, P>0.999; t=0.61, P=0.544; t=0.25, P=0.806; t=0.83, P=0.410) . The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) scores before radiotherapy in the study and the control groups were (60.24±5.13) points and (61.19±5.46) points, (74.12±7.20) points and (75.35±7.88) points at 1 month after radiotherapy, (77.53±7.14) points and (78.95±7.08) points at 6 months after radiotherapy, and (75.02±6.93) points and (76.68±6.74) points at 1 year after radiotherapy respectively, there were no statistically significant differences ( t=0.93, P=0.353; t=0.85, P=0.399; t=1.04, P=0.302; t=1.26, P=0.210) . The EORTC QLQ-C30 scores at 1 month, 6 months, and 1 year after radiotherapy were higher than those before radiotherapy in the two groups, and there were statistically significant differences (all P<0.001) . Conclusion:IMRT containing lymph node irradiation in the internal breast region after left breast cancer surgery brings a certain degree of increased cardiac dose, but it is feasible to control it within a certain range and does not affect the patients' cardiac function or quality of life in the short term.

Objective:To summarize the progress in research of economic evaluation of HIV vaccination strategies in the world, and provide reference for future decision-making and research on HIV vaccination.Methods:The key words used for literature retrieval were "HIV/AIDS", and "vaccine/vaccination" and "economic evaluation/cost-effectiveness analysis/cost-utility analysis/cost-benefit analysis/HTA". Literatures about the economic evaluation of HIV vaccination strategies published as of July 31, 2022, were retrieved from Wanfang Data (Wanfang), China Hospital Knowledge Database (CHKD), and PubMed databases. The quality of the articles was evaluated and analyzed comprehensively.Results:A total of 17 study articles with good quality were included. Results from the comprehensive analysis showed that HIV vaccination is a cost-saving or cost-effective strategy for key populations or the whole population. HIV vaccination could effectively reduce new infections and improve the quality of life of population. Factors, such as vaccine efficiency, coverage rate, price, and risk behavior change after vaccination, would affect the vaccination effect in different targeted populations.Conclusions:There were limited high-quality research data about the economic evaluation of HIV vaccination strategies. It is necessary to conduct in-depth research based on real-world evidence.
