Objective To analyze the clinical characteristic,treatment and prognosis of traumatic macular holes resulted from ocular contusion.Methods The clinical data of 47 cases with traumatic macular hole was retrospectively reviewed.The general condition of the patients was summarized,optical coherence tomography and multifocal electroretinogram (mfERG) were used to evaluate anatomic and functional outcomes.The patients were divided into observation group and surgery group by the treatment they received,and the prognosis was evaluated.Results Traumatic macular hole occurs mainly in male.In the observation group,the mean diameter of macular hole was(490.0±86.9) μm.During the 12 month follow up,the holes in 7 cases (33.3％) were closed spontaneously,Vision and diameters of 14 cases (57.1％) maintained stable for a long time,the vision of 1 case (3.3 ％) declined mildly and the diameter of 1 case (3.3％) enlarged slightly.Visual acuity was improved significantly at last follow up (Z=-2.40,P＜ 0.05).The amplitudes of N1 wave of mfERG increased both in central fovea and macular area(t=13.30,5.06;P＜0.05).These data suggests that the macular function was recovered well.In the surgery group,the mean diameter of macular hole was (643.3 ± 125.0) μm and statistically larger than that of the observation group (t=-4.76,P＜0.05).At the last follow-up,visual acuity were not improved significantly (Z=-1.79,P＞0.05).The amplitudes of N1 wave in 6 cases (23.1 ％) improved merely and the difference was not statistically significant (t =1.98,P ＞ 0.05).These data suggests that the macular function was recovered slightly only in a few patients.Conclusions A part of the patients with smaller diameters of macular holes may close spontaneously,and they may get better visual acuity.Vitrectomy may help to close the macular holes in some severe cases,but the improvement of functional outcomes is not significant.

Objective: To investigate the frequency , distribution and features of lymph node metastasis in lung cancer, and to provide evidence for lymph node dissection. Methods: 348 patients with lung cancer were retrospectively studied, all patients received R_3 surgery plus systemic lymph node dissection according to the mapping system developed by Naruke. Results: Total 3 689 groups of lymph nodes were dissected . The metastatic rates of N_1 and N_2 were 23.4% and 16.5%, respectively. N_1 or N_2 metastasis was not found in Tis tumor. There was a significant difference of N_2 metastasis rates between squamous cell carcinoma and adenocarcinoma in T_1 or T_2 tumor (P

Objective:To retrospectively analyze the survival outcomes of the surgical management of primary small cell carcino-ma of the esophagus. Methods:The medical records were reviewed for patients diagnosed with esophageal carcinoma and underwent esophagectomy from January 2000 to December 2009 at the Department of Thoracic Surgery of the Henan Cancer Hospital. We fo-cused on the clinical data of patients with small cell carcinoma of the esophagus. The Kaplan-Meier approach with log-rank test was used for survival analysis. Results:A total of 5,062 patients underwent esophagectomy with curative intent at the Department of Thorac-ic Surgery of the Henan Cancer Hospital;among which, 57 (1.1%) were diagnosed with small cell carcinoma of esophagus. The most common surgical approach was trans-left thoracic incision esophagectomy. Cervical esophagogastrostomy was performed for all pa-tients. The most common chemotherapy regimen was EP. The overall 5-year survival rate was 12.5%, and the median survival time was 45 months. Among the various stages, the 5-year survival rate and survival time were 25% and 50 months for Stage I, 5.9% and 43 months for Stage II, and 4.3%and 43 months for StageⅢ. Subgroup analysis showed that cases treated with surgery alone had poorer overall median survival time compared with those cases that underwent surgery plus chemotherapy (23.2 months vs. 60.7 months, re-spectively;P<0.01). Even for Stage I patients, thesurgery plus chemotherapysubgroup was associated with a significantly longer me-dian survival time than the surgery alone subgroup (81.9 months vs. 22.3 months, P<0.01). Conclusion:For patients with primary small cell carcinoma of the esophagus, surgery alone cannot provide the optimal prognosis. Surgery combined with systemic chemother-apy can improve the survival time.

Objective To investigate the efficacy of the hospital intensive treatment by auto-CPAP on elderly patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and to analyse the possible factors related to the effectiveness.Methods Subjects were selected from elderly OSAHS patients over 60 years old.The eligible subjects were divided into intensive treatment group and non-intensive treatment group (non-ITG).Patients in intensive treatment group were intensively treated using auto-CPAP for 3 consecutive days,assisted with targeted health education and guidance,and making proper adjustments to parameters of the auto-CPAP according to treatment outcomes at the previous day.But those in non-intensive treatment group were just treated with auto-CPAP for only 1 day,supplemented by regular health education and guidance.The apnea-hypopnea index (AHI),minimum oxygen saturation (SaO2min),mean oxygen saturation (SaO2mean) and the time spent at SaO2 lower than 90％ (tSaO2＜90％),the occurrence of clinical symptoms and adverse effect,Epworth sleepiness scale(ESS) were compared between both groups.The correlation analyses were also conducted.Results ESS (3.58±3.76 vs.6.84 ± 3.22),AHI [(7.85±6.53) time/h vs.(10.42±7.27) time/h] and tSaO2＜90％[(5.65±15.43) min vs.(15.26±33.14) min] were lower(t=6.902,2.760,2.765,allP＜0.05),while SaO2mean [(96.57±1.53)％ vs.(94.63±1.38)％] and SaO2min [(88.24±4.43)％ vs.(83.28±5.06)％]were higher(t=-9.870,-7.740,both P＜0.05)in intensive treatment group than in non intensive treatment group.The occurrences of clinical symptoms and adverse effect (except for skin allergy) were decreased in intensive treatment group versus non-ITG (all P＜0.05).The AHI after intensive treatment was decreased in females versus males [(7.85±5.19) times /h vs.(11.27±7.78) times/h,t=2.133,P＜0.05].BMI,age,gender and the state of OSAHS were correlated to AHI,SaO2 mean,SaO2 min and tSao2＜90％ after intensive treatment (all P＜0.05).Conclusions The hospital intensive treatment can improve the clinical results and decrease the occurrences of clinical symptoms and adverse effect for elderly OSAHS patients,and is expected to improve therapy compliance,and its curative efficacy is correlated to BMI,age,gender and state of OSAHS before therapy.

Objective To evaluate the reliability of PainVision method for assessment of postoperative pain in patients undergoing gynaecological laparoscopy.Methods Twenty ASA physical status Ⅰ-Ⅱ patients,aged 30-45 yr,undergoing gynaecological laparoscopy under fentanyl-propofol-cisatracurium anesthesia,were studied.Pain intensity was simultaneously assessed using PainVision method and visual analog scale (VAS) at 12,24 and 48 h after surgery.PainVision was a new method for quantitative measurement of pain intensity using a painless electrical stimulation (PainVision PS-2100 device).Pain degree was calculated from two parameters,current perception threshold and pain compatible electrical current by using PainVision.The former parameter was defined by the lowest electrical current detected ; the latter parameter defined by the electrical current judged as being compatible with the intensity of ongoing pain.Results There was a significant positive correlation between pain degree calculated by PainVision method and VAS scores,and the correlation coefficient was 0.902 (P ＜ 0.01).Conclusion PainVision method can be applied for assessment of postoperative pain in patients undergoing gynaecological laparoscopy.

Objective To investigate the role of phosphatidyl-inositol 3-kinase-Akt (PI3k-Akt) signal pathway in the attenuation of ischemia-reperfusion (I/R) injury by sevoflurane preconditioning in isolated rat hearts. Methods Ninety-six adult male SD rats weighing 220-280 g were randomly divided into 6 groups ( n = 16 each): sham operation group (group S); I/R group; sevoflurane preconditioning group (group SP); wortmannin group (group W); dimethyl sulfoxide (DMSO) group (group D) and sevoflurane preconditioning + wortmannin group (group SW) . Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95%O2-5%C02 at 37 ℃ . The hearts were continuously perfused for 180 min in group S. After 15 min of equilibration, the isolated hearts were subjected to 30 min of ischemia followed by 120 min of reperfusion in SP, W, D and SW groups. Croups SP, W, D and SW received 10 min of perfusion with K-H solution containing 2. 4% sevoflurane, 100 nmol/L wortmannin, 20 μmol/L DMSO, and 2.4% sevoflurane + 100 nmol/L wortmannin, respectively, followed by 5 min washout before I/R. Eight hearts in each group were selected and HR, left ventricular end-diabetic pressure (LVEDP), left ventricular developed pressure (LVDP), and ± dp/dtmax were recorded at the end of equilibration and at 15 min of reperfusion, Myocardial tissues were obtained at 15 min of reperfusion for determination of apoptosis (by TUNEL) and phosphorylated Akt (p-Akt) expression (by Western blot) . Another 8 hearts were selected at 120 min of reperfusion for determination of myocardial infarct size by TTC staining. Result Compared with group S, LVDP and ± dp/dt,^ were significantly decreased and LVEDP was significantly increased in groups I/R, SP, W, D and SW, and myocardial p-Akt expression was up-regulated in groups I/R, SP and D ( P ＜ 0.05). Compared with group I/R, LVDP and ± dp/dtmax were significantly increased, LVEDP and apoptosis index were significantly decreased, myocardial p-Akt expression was up-regulated, and myocardial infarct size was significantly reduced in group SP (P ＜0.05) . Conclusion Activation of PI3K-Akt signal pathway is involved in the attenuation of I/R injury by sevoflurane reconditioning in isolated rat hearts.

Objective:To explore the relationship between social support and negative emotion in parents of children with congenital heart disease before the operation.
Methods:Social support rating scale (SSRS), self-rating anxiety scale (SAS), and Center for epidemiological survey-depression scale (CES-D) were used to assess the association between social support and anxiety and depression in 226 parents.
Results:The mean SSRS score was signiifcantly lower than the normal. There was signiifcant difference in social support of parents in monthly family earning and knowledge about surgery. Parents with monthly family income≤1000 yuan had lower scores than the other groups. Parents who knew nothing about the surgery approach had lower scores. Social support was significantly correlated to negative emotion (anxiety and depression). Social support could predict anxiety and depression.
Conclusion:Social support is widely and significantly correlated to negative emotion in parents of children with congenital heart disease before the surgery.
