Objective To evaluate the feasibility and outcomes of different surgical approaches on the basis of sentinel lymph node biopsy (SLNB) in treating early-stage vulvar cancer, and discuss the proper strategy for individualized treatment. Methods The medical charts of patients with early-stage vulvar cancer treated in Sun Yat-sen University between January 2004 and December 2013 were retrospectively collected. A total of 74 patients who received sentinel lymph node(SLN)detection in primary surgery were enrolled (average age 55). The surgical approaches contained SLNB, inguinal lymphadenectomy (IL), and extensive vulvectomy. The SLN were examed on intraoperative frozen sections. The treatment protocols, lymphatic metastasis, postoperative recovery condition, recurrence and survival data were collected and analyzed. Results At least one SLN was successfully detected in 68 (92%,68/74) patients. SLN were positive in 21 patients, of whom 12 (group A) underwent bilateral IL, and 9 (group B) received radiotherapy without performed IL. SLN were negative in 47 patients, of whom 26 (group C) underwent bilateral IL and one of them had a non-SLN metastasis, and 21 (group D) were advised to follow-up. The coincidence of pathological results between frozen and paraffin sections was 100%. The sensitivity and specificity of SLNB for diagnosis of lymph node metastasis were 95% and 100%, respectively. A total of 44 complications happened in patients underwent SLNB and IL (group A and C), including 16 poor wound healing, 14 lymphedema, 8 lymphatic fistulas, 3 phlebothrombosis and 3 infections. There were no complications happened in patients underwent SLNB alone (group B and D), among whom the operation time, bleeding amount, and hospital stay were also significantly less than those in patients underwent SLNB and IL. The median follow-up time was 41 months and the 3-year overall survival rate was 85% in the whole series. Recurrences were observed in 11 patients and 9 of them died of the tumor with the median survival time of 15 months. In patients with positive SLN (group A and B), the 3-year overall survival rate was 58% with 8 patients died of the disease, including 4 in group A and 4 in group B. In patients with negative SLN (group C and D), the 3-years overall survival rate was 97% with one patient in group D died of the tumor, and significantly higher than that of patients with positive SLN (P=0.003). The 3-year overall survival rate was significantly difference. In univariate analysis by log-rank test showed that, neither in patients with nor without SLN metastasis the prognosis differed with respect to surgical approaches (group A vs B, P=0.709;group C vs D, P=0.253). Univariate analysis by log-rank test showed that, lymph node metastasis, pathological grade, depth of invasion, and tumor location could significantly affected survival (P<0.05), whereas age, tumor diameter, and surgical approach didn′t (P>0.05). Multivariate analysis showed that lymph node metastasis (RR=21.57, 95%CI:2.68-173.10, P=0.002) and tumor location (RR=7.85, 95%CI:1.79-34.50, P=0.024) were the independent factors for overall survival. Conclusions Lymph node metastasis is an independent prognosis factor for patients with early-stage vulvar cancer. SLNB could accurately diagnose the status of lymph nodes and help to decide subsequent treatment. The omissions of IL in patients with negative SLN avoid surgical morbidity and shorten postoperative recovery period without an increased risk of recurrence.

Objective To observe the change of capillary pericapillary cells in rats with myocardial infarction and the influence of supplementing qi and activating blood circulation herbs, and explore its mechanism of improving myocardial perfusion. Methods The rat model was established by ligaturing the left anterior descending coronary artery. On the base of ECG evaluation, successfully modeled rats were randomly divided into the model group, group treated with supplementing qi and activating blood circulation Chinese medicine (activating blood and supplementing qi group), group treated with Perindopril (Perindopril group), group treated with Tongxinluo Capsules (Tongxinluo group). The sham-operation group was taken as the control. There were totally 5 groups. The model group and the sham-operation group were treated with normal saline. The changes of myocardial capillary density (MCD) and number of pericapillary cells on the 7th, 28th day after medicinal administration were observed. Results On the 7th and 28th day, the MCD decreased significantly and the number of capillary pericapillary cells increased significantly in the model group compared with the sham-operation group (P<0.01). The MCD increased significantly in the activating blood and supplementing qi group, Perindopril group and Tongxinluo group compared with the model group (P<0.01). The number of pericapillary cells decreased significantly in the activating blood and supplementing qi group, Perindopril group and Tongxinluo group compared with the model group (P<0.01). Conclusion The supplementing qi and activating blood circulation herbs can improve regional myocardial blood supply by decreasing the number of pericytes and promoting regeneration of capillary.

Objective To determine the electrocardiographic (ECG) characteristics of myocardial infarction (MI) evolution in rats and the intervention effect of Chinese herbs, and to provide basis for the establishment of the criteria for ECG diagnosis and assessment of drug therapeutic effects of rats MI. Methods Totally 140 male SD rats were randomly divided into sham operation group, model group, replenishing qi group, activating blood group, replenishing qi and activating blood (1∶2) and (2∶1) group as well as Tongxinluo group, each group with 20 rats. The rat MI model was established by ligating the left anterior descending coronary artery. The treatment groups were administrered with corresponding drugs by gavage from the first day after operation. The sham operation group and model group were given the same volume of distilled water. The 12-lead ECGs were recorded before, immediately after, 1st and 2nd week after operation respectively. The voltage value of ST segment deviation, the time limit of QRS complex and the number of animals with pathologic Q wave were evaluated for statistical analysis. Results Model group showed the elevation of ST segment, significantly prolonged time limit of QRS complex (P<0.01), and no pathologic Q wave showed immediately after operation compared with sham operation group. And all above observational indexes reached the peak at 1st week and declined at 2nd week after operation. Compared with model group at 2nd week after operation, replenishing qi and activating blood (1∶2) group and (2∶1) group all presented remarkable dropping of ST segment, shortening in time limit of QRS complex and reduction in number of rats with pathologic Q wave, of which 2∶1 group showed the most (P<0.01). Activating blood group only displayed decreases in time limit of QRS and number of rats with pathologic Q wave (P<0.05), and no significant decline in ST segment. Replenishing qi group demonstrated no significant changes in above three observational indexes (P>0.05). Thus, we proposed the criterion for the ECG diagnosis of rats MI as well as the criterion for the ECG assessment of drug therapeutic effects of rats MI. Conclusion ECG can overall and sensitively evaluate the evolution and drug therapeutic effects of MI in rats, thus providing a relatively objective and available assessment method for the experimental studies of myocardial ischemic diseases.

OBJECTIVE: To investigate the clinical characteristics of and prognostic factors for primary malignant melanoma of the vagina. METHODS: Clinical data from 31 patients treated for primary malignant melanoma of the vagina at the Sun Yat-sen University Cancer Center between March 1970 and June 2005 were retrospectively analyzed. RESULTS: The median age was 58 years (range, 18 to 73 years), and the main symptoms reported were vaginal bleeding and vaginal discharge. Most tumors were of the nodular type and classified as stage I according to International Federation of Gynecology and Obstetrics staging criteria. Surgery was performed on 22 patients, chemotherapy was administered to 7 patients, and immunotherapy was administered to 19 patients. Recurrent tumors developed in 11 patients (35.5%) during a median follow-up period of 20.2 months (range, 1 month to 18 years). The 5-year overall survival rate was 32.3%. Univariate analysis revealed that macroscopic tumor growth and the treatment method significantly affected survival outcome (p=0.039 and p<0.001, respectively), whereas the radicality of surgery did not (p=0.296). Multivariate analysis revealed that macroscopic tumor growth (hazard ratio [HR], 4.1; 95% confidence interval [CI], 1.4 to 12.1; p=0.010) and treatment method (HR, 0.3; 95% CI, 0.1 to 0.9; p=0.025) were independent prognostic factors for overall survival. CONCLUSION: Patients with primary vaginal melanoma have a poor prognosis. Macroscopic tumor growth and treatment method are prognostic factors for primary malignant melanoma of the vagina.

Objective:
To estimate the impact of lymph node dissection on survival in patients with apparent early-stage epithelial ovarian cancer (EOC).
Methods:
We conducted a retrospective review of patients with clinical stage I–II EOC. All patients underwent primary surgery at Sun Yat-sen University Cancer Center between January 2003 and December 2015. Demographic features and clinicopathological information as well as perioperative adverse events were investigated, and survival analyses were performed.
Results:
A total of 400 ovarian cancer patients were enrolled, and patients were divided into 2 groups: 81 patients did not undergo lymph node resection (group A), and 319 patients underwent lymph node dissection (group B). In group B, the median number of removed nodes per patient was 25 (21 pelvic and 4 para-aortic nodes). In groups A and B, respectively, the 5-year progression-free survival (PFS) rates were 83.3% and 82.1% (p=0.305), and the 5-year overall survival (OS) rates were 93.1% and 90.9% (p=0.645). The recurrence rate in the retroperitoneal lymph nodes was not associated with lymph node dissection (p=0.121).The median operating time was markedly longer in group B than in group A (220 minutes vs. 155 minutes, p<0.001), and group B had a significantly higher incidence of lymph cysts at discharge (32.9% vs. 0.0%, p<0.001).
Conclusion
In patients with early-stage ovarian cancer, lymph node dissection was not associated with a gain in OS or PFS and was associated with an increased incidence of perioperative adverse events.

OBJECTIVE: Visual search is an important attention process that precedes the information processing. Visual search also mediates the relationship between cognition function (attention) and social cognition (such as facial expression identification). However, the association between visual attention and social cognition in patients with schizophrenia remains unknown. The purposes of this study were to examine the differences in visual search performance and facial expression identification between patients with schizophrenia and normal controls, and to explore the relationship between visual search performance and facial expression identification in patients with schizophrenia. METHODS: Fourteen patients with schizophrenia (mean age=46.36+/-6.74) and 15 normal controls (mean age=40.87+/-9.33) participated this study. The visual search task, including feature search and conjunction search, and Japanese and Caucasian Facial Expression of Emotion were administered. RESULTS: Patients with schizophrenia had worse visual search performance both in feature search and conjunction search than normal controls, as well as had worse facial expression identification, especially in surprised and sadness. In addition, there were negative associations between visual search performance and facial expression identification in patients with schizophrenia, especially in surprised and sadness. However, this phenomenon was not showed in normal controls. CONCLUSION: Patients with schizophrenia who had visual search deficits had the impairment on facial expression identification. Increasing ability of visual search and facial expression identification may improve their social function and interpersonal relationship.

OBJECTIVETo evaluate the clinical outcome of extended retroperitoneal lymphadenectomy as surgical therapy for adenocarcinoma of the head of the pancreas.
METHODSTwenty patients with adenocarcinoma of the head of the pancreas were treated by standard pancreatoduodenectomy (standard group) between 1994 and 1997, and 46 patients with the same disease underwent extended retroperitoneal lymphadenectomy associated with standard pancreatoduodenectomy (radical group) between 1998 and 2002. Clinical and pathological parameters in both groups were reviewed. The postoperative morbidity, mortality, and survival data were compared.
RESULTSThe mean total number of lymph nodes resected was significantly higher in the radical group than in the standard group (P < 0.05). Of the 46 patients in the radical group, 26.09% (12/46) had metastatic adenocarcinoma in the resected retroperitoneal lymph nodes. There was one perioperative death in the standard group and two in the radical group. Postoperative diarrhea and lymphatic leakage were only observed in the radical group. Transfusion requirements and postoperative morbidity did not differ between the two groups. The 1-, 2-, and 3-year survival rates were 63.16%, 31.58%, and 21.05% in the standard group, and 65.91%, 37.71%, and 21.21% in the radical group (P > 0.05). When the subgroups of patients with positive lymph nodes were analyzed, the 1-, 2-, and 3-year survival rates were 41.67%, 16.67%, and 8.33% in the standard group, and 64.52%, 32.26%, and 12.9% in the radical group (P < 0.05). A trend toward a better survival was observed in the first 2 years after operation in the radical group, but with no significant differences 2 years later.
CONCLUSIONThe addition of an extended lymphadenectomy may improve the early survival without increasing the morbidity, but has no significant effect on long-term survival.

BACKGROUNDNowadays, there is a remarkable rise in resectability rate of periampullary adenocarcinoma and the mortality and morbidity of the pancreaticoduodenectomy procedure have been reduced remarkably, while the 5 year survival rates of patients with carcinoma of the head of the pancreas are still below 25%. We conducted this retrospective study to evaluate the clinical outcome of radical pancreaticoduodenectomy with extended retroperitoneal lymphadenectomy as a surgical therapy for adenocarcinoma of the head of the pancreas.
METHODSTwenty cases with adenocarcinoma of the head of the pancreas were treated by standard pancreaticoduodenectomy (removing only the peripancreatic lymph nodes en bloc with the tumour) from 1994 to 1997, and 46 cases with the same disease underwent extended retroperitoneal lymphadenectomy associated with standard pancreaticoduodenectomy from 1998 to 2002. The patients for whom there were insufficient follow-up data, or who had received postoperative adjuvant therapy, were excluded from the analysis. Clinical and pathological parameters of both groups were reviewed. The postoperative morbidity, mortality and survival data were compared statistically.
RESULTSDemographic and histopathological characteristics were similar in the two groups of patients. Performance of the extended lymphadenectomy lengthened the procedure. The mean total number of lymph nodes resected was significantly higher in the radical group (P < 0.05). Of the 46 cases in the radical group, 26% (12/46) had metastatic adenocarcinoma in the resected retroperitoneal lymph nodes. There was one perioperative death in the standard group, and two in the radical group. Postoperative diarrhoea and lymphatic leakage were only observed in the radical group. Transfusion requirements and postoperative morbidity rates did not differ between the two groups. The 1-, 2- and 3-year survival rates were 63%, 32% and 21% respectively in the standard group, and 66%, 38% and 21% in the radical group. No statistically significant difference was found between the groups. When subgroups of node positive patients were analysed, the 1-, 2- and 3-year survival rates were 42%, 17% and 8% respectively in the standard group, and 65%, 32% and 16% in the radical group. Better survival was observed in the first 2 years after operation in the radical group, but no survival differences were seen after 2 years post operation.
CONCLUSIONSThe addition of an extended lymphadenectomy to a pancreaticoduodenectomy did not significantly increase morbidity rates, but was associated with an early survival advantage.

OBJECTIVETo observe effects of syndrome-differentiation acupuncture on life quality in patients with functional dyspepsia (FD) in order to evaluate its clinical efficacy.
METHODSOne hundred and five cases of FD were randomly divided into a syndrome-differentiation acupuncture group, a regular acupuncture group and a non-acupoint group, 35 cases in each one. Zhongwan (CV 12), Tianshu (ST 25), Zusanli (ST 36) were selected as main acupoints in the syndrome-differentiation acupuncture group. After syndrome differentiation, Danzhong (CV 17) and Zhangmen (LR 13) were added for those with stagnation of liver qi; Pishu (BL 20) and Weishu (BL 21) were added for those with deficiency of spleen-stomach qi; Qimen (LR 14) and Taichong (LR 3) were added for liver-qi invading stomach and Yinlingquan (SP 9) and Neiting (ST 44) were added for dampness-heat blocking stomach. The selection of acupoints in the regular acupuncture group was the same as main acupoints in the syndrome-differentiation acupuncture group. The points 10 mm lateral to the main acupoints were selected in the non-acupoint group. The treatment was given once a day, six days as a treatment course and totally two courses were required. The symptom total score, health-related quality of life survey (SF-36) and Nepean dyspepsia index (NDI) were evaluated before and after the treatment as well as one month after the treatment (follow-up visit), respectively. The efficacy was also assessed.
RESULTSAfter the treatment, the total effective rate was 87.5% (28/32) in the syndrome-differentiation acupuncture group, which was superior to 74.2% (23/31) in the regular acupuncture group and 20.7% (6/29) in the non-acupoint group (P < 0.05, P < 0.01). Compared before the treatment, the SF-36, NDI and symptom total score after the treatment and in the follow-up visit were all obviously improved in the syndrome-differentiation acupuncture group and regular acupuncture group (all P < 0.05), which was the most obvious in the syndrome-differentiation acupuncture group [after the treatment, SF-36: 84.54 +/- 5.93 vs 81.44 +/- 6.22, 63.46 +/- 6.59; NDSI: 18.94 +/- 9.30 vs 21.23 +/- 8.39, 43.93 +/- 11.26; NDLQI: 71.42 +/- 7.23 vs 63.11 +/- 7.06, 54.87 +/- 6.00; symptom total score: 22.06 +/- 15.80 vs 32.52 +/- 16.88, 47.97 +/- 10.92]; the improvement in the regular acupuncture group was more obvious than that in the non-acupoint group (P < 0.01, P < 0.05). Compared before the treatment, only NDSI score was improved in the non-acupoint group after the treatment (P < 0.05).
CONCLUSIONThe syndrome-differentiation acupuncture could obviously improve patient's life quality in the treatment of FD, which is an effective therapy for FD.
