ObjectiveTo observe the effect of Xuesaitong Capsule on stroke patients in recovery phase.Methods427 patients with stroke were randomly divided into 3 groups, group Ⅰ(take in aspirin), group Ⅱ(take in Xuesaitong), group Ⅲ(take both medicine). The Europe Stroke Scale (ESS), Barthel index (BI) and blood rheology were compared among these three groups.ResultsESS and BI score of group Ⅱ were higher than that of group Ⅰ, but lower than that of group Ⅲ. The recurrence rate and blood rheology index was similar in group Ⅰand Ⅱ, but higher than that of group Ⅲ.ConclusionBoth Xuesaitong Capsule and aspirin are effectivity on stroke in recovery phase, but it is better to take in both medicines.

Objective To provide the anatomical basis for the flap based on the perforator of Plantar arch,through investigation of the morphological features of the perforator of the arch of the foot.Methods From November,2015 to March,2016,the first metatarsal base and the fifth metatarsal tuberosity were chosen as the observation point on 25 specimens of adult human feet perfused with red latex.The following contents were observed under surgical magnifier:①The origin,courses,branches and distribution of the perforator of Plantar arch.②The anastomoses among the perforator of Plantar arch and the fete arteriosum dorsale pedis.Mimic operation was performed on another fresh specimen perfused with red latex.Results There were 3 perforators in Plantar arch,which passed through the 2nd-4th metatarsal dorsal muscles to the dorsi pedis and then divided into an ascending branch and a descending branch.The ascending branch anastomosed with the rete arteriosum dorsale pedis,and the descending branch stretched to the 2nd-4th plantar arteries.The initiative outer diameters of the 1st-3rd dorsal perforators of Plantar arch were (1.5 ± 0.3)mm,(1.1 ± 0.4) mm and (0.9-± 0.3) mm respectively,and the lengths of the stem were (1.1 ± 0.2) cm,(1.5 ± 0.1) cm and (1.5 ± 0.5) cm respectively.Conclusion The flap can be used for repair of soft-tissue defects of dorsal and front foot through dorsal transposition or a V-Y advancing flap with the perforator of Plantar arch as its vascular pedicle.

Objective To investigate the stress response and postoperative recovery state of vaginal(VH) versus abdominal hysterectomy(AH). Methods A total of 220 cases schedulced for total hysterectomy for benign disease were randomly divided into the VH and AH group,each consisting of 110 cases, receiving VH and AH respectively. Circulating blood glucose(Glu), IL-6, and CRP levels were measured preoperative-ly,2h and 1 day after operation between both two groups,and the operative duration,intraoperative blood loss,time of anal gas passage and postoperative hospital stay were compared between both two groups. Results The intraoperative blood loss,time of anal gas passage and post-operative hospital stay were markedly less in the VH group than in the AH group,with significant differences between two groups,all P <0.01 (t = 8.939,18.762, and 8.727 respectively), while the operative duration was not different, P> 0.05(t = 1.922). The serum IL-6 level was con-siderably lower 2h postopeartion in the VH group than in the AH group,and the levels of IL-6 and CRP 1 day after operation remained the same, with significant differences, all P < 0.01 (t =41.459, 16.711, and 24.281 respectively). No significant differences were noted at the other point between two groups,all P> 0.05. Conclusion VH proves to have less stress response as compared to AH,with better postoperative re-covery.

Objective To explore the feasibility of the perforator-based intermediate dorsal pedal flap with vessels of cutaneous nerve nutrition for repair of soft tissue defects of the forefoot.Methods A retrospective case series study was performed for seven cases of soft tissue defects of the forefoot hospitalized between February 2013 and January 2017.There were five males and two females,with a mean age of 38 years (range,18-73 years).Injury regions were lateral plantar skin defect in the forefoot in three cases,dorsal skin defect in the third webbed toe in two cases and proximal dorsal skin defect in the fourth toe in two cases.The defect area was about 2.5 cm × 1.5 cm-4.5 cm × 2.0 cm.The perforator-based intermediate dorsal pedal flap with vessels of cutaneous nerve nutrition was designed on the lateral dorsum of the foot and then was incised and transferred to repair the forefoot wound based on its surgical anatomy.The time of surgery and the amount of intraoperative blood loss were recorded.An observation was done on feeling,appearance,texture,blood supply and survival of the flap as well as swelling,hypertrophic scar,itching,paralysis of the skin grafting area.The recovery of the activity function was assessed by American Orthopedic Foot & Ankle Society (AOFAS) score.Results The surgery time was 1.0-1.5 h (mean,1 h),and intraoperative bleeding was about 50 ml (range,30-100 ml).Seven cases of perforator-based dorsal medial skin flap with vessels of cutaneous nerve nutrition all survived,with early wound healing.After 2 to 15 months follow-up,two-point discrimination of flaps was 9-15 mm(average,12.5 mm).Skin flaps were with excellent texture and without swelling,the color of which was close to normal color with good appearance.The postoperative foot did not have bone resorption,wound infection,tendon adhesion,line-type or flaky scar left locally,lower limb walking dysfunction or other complications.Patients were satisfied with the functions of donor and recipient sites and the appearance of the flap.Conclusions Perforation-based dorsal flap with vessels of cutaneous nerve nutrition has high survival rate,satisfaction of appearance and fast recovery of recipient site,with no obvious foot pain,limitation of joint movement or other complications,and therefore is a reliable method to repair soft tissue defects in forefoot.

Objective: To investigate the feasibility and safety of the medial approach "four-step method" in the laparoscopic mobilization of splenic flexure. Methods: A retrospective cohort study was performed. Clinical data of 157 colorectal cancer patients undergoing the medial approach "four-step method" in the laparoscopic mobilization of splenic flexure at Gastrointestinal Surgical Department of Guangdong Provincial People′s Hospital from July 2015 to June 2018 were retrospectively analyzed. Of 157 cases, 17 were transverse colon cancer, 94 were descending colon cancer, 25 were sigmoid cancer and 21 were rectal cancer; 89 were male and 68 were female; mean age was (61.8±10.3) years and mean body mass index was (23.2±3.7) kg/m². The medial approach "four-step method" in the laparoscopic mobilization of splenic flexure was performed as follows: (1) The root vessels were treated with the "provocation" technique to expand the Toldt′s gap. This expansion was extended from the lateral side to the peritoneum reflex of left colonic sulcus, from the caudal side to the posterior rectal space, and from the cephalad side to the lower edge of pancreas. (2) The left colonic sulcus was mobilized, converging with the posterior Toldt′s gap. Mobilization was carried out from cephalad side to descending colon flexure, freeing and cutting phrenicocolic ligament and splenocolic ligament, and from caudal side to peritoneal reflex. (3) Gastrocolic ligament was moblized. Whether to enter the great curvature of stomach omentum arch when the gastrocolic ligament was cut, that was, whether to clean the fourth group of lymph nodes, should be according to the tumor site and whether serosal layer was invaded. (4) Transverse mesocolon was moblized and transected at the lower edge of the pancreatic surface, merging with the posterior Toldt′s gap, and from lateral side to lower edge of the pancreatic body, merging with the lateral left paracolonic sulcus. Safety and short-term clinical efficacy of this surgical procedure was summarized. Results: All the patients completed this procedure. During operation, 3 cases were complicated with organ injury, including 1 case of colon injury, 1 case of spleen injury and 1 case of pancreas injury. No operative death and conversion to open surgery was found. The average operation time was (147.5±35.1) minutes, the average intra-operative blood loss was (40.8±32.7) ml and the average number of harvested lymph node was (16.1±5.8), including (4.0±2.3) of positive lymph nodes. The first exhaust time after surgery was (41.3±20.6) hours, the fluid intake time was (1.5±1.3) days, the postoperative hospital stay was (5.2±2.3) days. Eight (5.1%) cases developed postoperative complications, and all were improved and discharged after conservative treatments. According to the TNM classification system, postoperative pathology revealed that 31 patients were stage I, 51 were stage II, 53 were stage III, 22 were stage IV. Conclusion The medial approach "four-step method" is safe and feasible, which can effectively decrease the operation difficulty of the laparoscopic mobilization of the splenic flexure.

Objective: To investigate the morphological characters of the dorsal perforators originated from the deep palmar arch, so as to provide anatomic basis for V-Y advanced perforator flap. Methods: The following contents were investigated in 30 adult hand specimens perfused with red latex under surgical magnifier: ①The origin, courses, branches and distribution of the dorsal perforators originatedd from the deep palmar arch. ②The characters of anastomosis among the dorsal perforators, the dorsal carpal and metacarpal arteries. Mimic operation was performed on another fresh specimens perfused with red latex. Results: There were three perforators originated from the deep palmar arch, which passed through the 2nd-4th dorsal interossei and then divided into an ascending branch and a descending branch at the dorsum of hand. Then the ascending branch anastomosed with the dorsal carpal artery, and the descending branch stretched to the 2nd-4th dorsal metacarpal arteries. The originating outer diameters of the 1st-3rd perforators were (1.1±0.2) mm, (0.9±0.3) mm and (0.7±0.1) mm respectively, and the length of the stems were (1.1±0.3) cm, (1.0±0.2)cm and (0.9±0.1) cm respectively. Conclusions The V-Y advanced perforator flap with the dorsal perforator of the deep palmar arch as its vascular pedicle could be used to repair the dorsal carpal or dorsal metacarpal soft tissue defects.

The clinicopathological data of 170 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to Guangdong Provincial People′s Hospital from January 2010 to December 2018 were collected. There were 125 males and 45 females, aged from 30 to 85 years, with a median age of 64 years. Of the 170 patients, 82 cases undergoing proximal gastrectomy were allocated into the proximal gastrectomy group and 88 cases undergoing total gastrectomy were allocated into the total gastrectomy group. Observation indica-tors: (1) surgical and postoperative situations; (2) follow-up and survival; (3) analysis of prognostic factors. Follow-up was conducted using telephone interview and outpatient examination to detect survival of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measure-ment data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan-Meier method was used to draw survival curves, and Log-Rank test was used for survival analysis. COX proportional hazard model was used for univariate and multivariate analyses. Variables with P<0.1 in univariate analysis were included for multivariate analysis. Results:(1) Surgical and postoperative situations. Cases with surgical approach as transthoracic or thoraco-abdominal approach, transabdominal approach, the operation time, cases with volume of intra-operative blood loss ≤100 mL or >100 mL, cases with length of proximal margin ≤1.5 cm or >1.5 cm, cases with radical surgery outcome as R 0, R 1, R 2, the number of lymph nodes harvest, cases with anastomotic leakage, cases with anastomotic stricture, cases with incision infection, cases with pleural infection or effusion, cases with abdominal infection or ascites were 61, 21, (211±18)minutes, 46, 36, 44, 38, 73, 6, 3, 15(9,22), 5, 2, 2, 4, 2 in the proximal gastrectomy group, respec-tively.

There was no significant difference in the length of proximal margin or radical surgery outcome between the two groups ( χ2=0.11, Z=-0.95, P>0.05) and there was no significant difference in the anastomotic leakage, anastomotic stricture, incision infection, pleural infection or effusion, abdominal infection or ascites between the two groups ( P>0.05). (2) Follow-up and survival. All the 170 patients were followed up for 89(64,106)months. Of the 170 patients, the 5-year overall survival rates were 43.8% and 35.5% of the Siewert type Ⅱ and Ⅲ AEG patients, respectively, showing no significant difference between them ( χ2=0.87, P>0.05). Of the patients with Siewert type Ⅱ AEG, the 5-year overall survival rates were 41.7% and 54.3% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=1.05, P>0.05). Of the patients with Siewert type Ⅲ AEG, the 5-year overall survival rates were 31.3% and 37.5% in the patients with proximal gastrectomy and the total gastrectomy, respectively, showing no significant difference between them ( χ2=0.33, P>0.05). The 5-year overall survival rates were 39.0% and 44.2% in the proximal gastrectomy group and the total gastrectomy group, respectively, showing no significant difference between the two groups ( χ2=0.63, P>0.05). Of the patients in TNM stage Ⅰ, stage Ⅱ, stage Ⅲ, the 5-year overall survival rates were 65.3%, 36.3%, 27.1% in the proximal gastrectomy group, versus 83.3%, 48.0%, 39.7% in the total gastrectomy group, showing no signifi-cant difference between the two groups ( χ2=0.02, 1.50, 1.21, P>0.05). (3) Analysis of prognostic factors. Results of univariate analysis showed that pathological N staging, degree of tumor differen-tiation and radical surgery outcome were related factors influencing prognosis of AEG patients ( hazard ratio=1.71, 1.70, 2.85, 95% confidence interval as 1.16-2.60, 1.15-2.50, 1.58-5.14, P<0.05). Results of multivariate analysis showed that pathological N staging and radical surgery outcome were independent factors influencing prognosis of AEG patients ( hazard ratio=1.55, 2.18, 95% confidence interval as 1.05-2.31, 1.18-4.02, P<0.05). Conclusions:There is no significant difference in the prognosis of Siewert type Ⅱ and Ⅲ AEG patients undergoing proximal gastrectomy or total gastrectomy. Proximal gastrectomy can be used for the treatment of advanced Siewert type Ⅱ and Ⅲ AEG.

Objective To explore the anatomical characteristics of mediate dorsal pedal cutaneous nerve and its nutritional vessels to provide anatomical basis of the perforator pedicle flap based on the medial dorsal pedal neurocutaneous vessels for repairing the forefoot soft-tissue defects.Methods From December,2016 to April,2017,the following contents were investigated in 30 adult feet specimens perfused with red latex:①The course,branches and distribution of the medial dorsal pedal cutaneous nerve.②The origin,course,branches and distribution of the nutrient vessels of the medial dorsal pedal neurocutaneous vessels.Mimic operation was performed on 1 fresh specimen.Results ①The mediate dorsal pedal cutaneous nerve mainly arose from the medial branch of the superficial peroneal nerve and processed forward for a distance of (2.5±0.4) cm under the surface of the inferior extensor retinaculum,and then divided into the mediate dorsal branch,the 1st and 2nd dorsal metatarsal branch over part of the dorsal pedal and digital skin.②The medial dorsal pedal neurocutaneous vessels were multiple segmental and polyphyletic,mainly include dorsalis pedis artery proximal perforator,the first metatarsal proximal perforator,the tibial proper plantar digital artery of the great toe and the perforater of the second toe web artery,of which the first metatarsal proximal perforator was most associated with operating methods.The first metatarsal proximal perforator perforate through the deep fascia to the subcutaneous area within the range of 1.0-2.0 cm near the proximal first plantar gap,the piercing point of which on deep fascia was constant,and the anatomical plane of the first metatarsal proximal perforator was higher than that of both the perforator of the toe web artery and the tibial proper plantar digital artery of the great toe.The first metatarsal proximal perforator divide into a large number of branches,which closely anastomose with adjacent perforators and other medial dorsal pedal neurocutaneous vessels.③Simulated surgery showed that the first metatarsal proximal perforation pedicle flap to meet the forefoot soft tissue defect repair.Conclusion The first metatarsal proximal perforator is constant in piercing point and reliable in blood supply,and it have a higher anatomical plane than that of both the perforator of the toe web artery and the tibial proper plantar digital artery of the great toe.The first metatarsal proximal perforator-based medial dorsal pedal neurocutaneous vascular flap can be transferred to repair the soft-tissue defects of forefoot.

Objective: To explore the clinical effects of dorsal perforator fascia pedicle flap of the deep palmar arch in the repair of skin and soft tissue defects of finger web area. Methods: Eleven patients (7 males and 4 females, aged from 18 to 73 years) with soft tissue defects of finger web area in distal dorsal side were admitted to Xinhua Hospital (Chongming) of Shanghai Jiao Tong University School of Medicine from October 2010 to September 2018. The sizes of skin and soft tissue defects ranged from 2.5 cm×1.5 cm to 6.0 cm×2.5 cm. According to the origin, course, branches, and distribution of the dorsal perforator of deep palmar arch, and the anatomical characteristics with vascular network of dorsal carpal and dorsal metacarpal, dorsal perforator fascia pedicle flaps of the deep palmar arch from the back of the injured hands were designed and transferred to repair the wounds of finger web area in distal dorsal side. The sizes of the flaps of patients ranged from 3.5 cm×2.0 cm to 6.5 cm×3.0 cm. The donor sites were sutured directly or covered with free forearm full-thickness skin graft. The clinical effects and swelling degree of flaps in early and late stages were evaluated during the follow-up of 3 to 36 months post surgery. Results: All the flaps survived in 11 patients, the incisions in donor and recipient sites were healed. During the follow-up of 3 to 36 months post surgery, the survival of flaps was good, and the appearance, color, and elasticity were close to normal skin, with two-point discrimination distance of 7 to 10 mm and sensory function recovery of grade S₃. The wounds in donor site had small scar without infection. The efficacy was evaluated as satisfactory in 8 patients, general in 3 patients, and dissatisfactory in no patient. Flap swelling rating in early stage was 1st degree in 7 patients, 2nd degree in 2 patients, and 3rd degree in 2 patients. Flap swelling rating in late stage was 1st degree in 8 patients, 2nd degree in 2 patients, and 3rd degree in 1 patient. The extension and flexion of the metacarpal and interphalangeal joints were basically normal and the patients were satisfied with the outcomes. Conclusions Based on the dorsal perforator of deep palmar arch, dorsal perforator fascia pedicle flap of the deep palmar arch is reliable to transfer to repair skin and soft tissue defects of finger web area in distal dorsal side, which is worthy of promotion in clinic.
