Objective:To evaluate a transhiatal tunnel flap designed to reconstruct the cardiac functional structure in proximal gastric cancer patients in our center.Methods:A descriptive case study method was used to select the data of 11 patients undergoing surgery for upper gastric cancer from Jan to Jul 2024. After laparoscopic dissection is completed, the esophagus is transected 2 cm from the upper edge of the tumor and the specimen is removed. The distance from the lower edge of the tumor is 5 cm. The cutting width is 4 cm, and the length of sleeve distal stump stomach is 20 cm. A seromuscular flap tunnel was made with a length of 2 cm and a width of 2 cm, 2 cm away from the top of the remnant stomach. The digestive tract was reconstructed using the Overlap hybridization method.Results:The median operation time was 175 (139-285) minutes. The median muscle flap production time and reconstruction time was 10.5 (5.5-21.0) minutes and 15.0 (11.8-33.6) minutes, respectively. The median blood loss is 50 (20-100) ml. The median postoperative hospitalization was 8 (6-25) days. The median tumor size was 2.5 (1.0-4.0) cm, and 31 (15-52) lymph nodes were dissected. The median follow-up after surgery was 3.5 (0.7-6.0) months, and no tumor recurrence or metastasis was found. Postoperative anastomotic leakage (Clavien-Dindo grade Ⅱ) occurred in one case, and there was no perioperative death. The Visick score of the whole group was 1 point in 8 cases and 2 points in 3 cases, and there was no anastomotic stenosis. Reflux esophagitis (Los Angeles classification grade B) was found in 1 case after gastroscopy, and the symptoms were relieved by conservative treatment.Conclusion:The transhiatal tunnel flap arthroplasty method has high surgical safety, low reconstruction difficulty, and an reliable anti-reflux effect.

Objective:To evaluate the effects of different volumes of ropivacaine for iliopsoas muscle plane block on quadriceps strength in patients undergoing hip arthroplasty.Methods:In this prospective study, 75 patients of either sex, aged 40-80 yr, with a body mass index of 18.5-30.0 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, undergoing elective hip arthroplasty from June to December 2023 at Baoding First Central Hospital, were randomized into 3 groups ( n=25 each) by using a computer-generated randomization sequence: ropivacaine 5 ml group (group Ⅰ), ropivacaine 10 ml group (group Ⅱ), and ropivacaine 15 ml group (group Ⅲ). Before induction of anesthesia, iliopsoas muscle plane block was performed with 0.5% ropivacaine 5, 10 and 15 ml in Ⅰ, Ⅱ and Ⅲ groups, respectively. The lateral femoral cutaneous nerve block was carried out using 0.5% ropivacaine 5 ml in all the three groups. The quadriceps muscle strength and status of quadriceps motor block in the affected limb were assessed on admission to postanesthesia care unit (PACU) and at 2, 4, 6, 24 and 48 h after surgery. The consumption of dezocine, score for patient′s satisfaction with analgesia, and occurrence of complications were recorded. Results:Compared with group Ⅰ, the quadriceps muscle strength scores were significantly decreased on admission to PACU and at 2, 4 and 6 h postoperatively in group Ⅲ, the rate of quadriceps motor block was significantly increased on admission to PACU in group Ⅱ, and the rate of quadriceps motor block was significantly increased on admission to PACU and at 2 and 4 h postoperatively in group Ⅲ ( P<0.05), and the consumption of dezocine was significantly decreased in group Ⅱ and group Ⅲ ( P<0.05). Conclusions:The recommended volume of ropivacaine for iliopsoas plane block is 10 ml in patients undergoing hip arthroplasty.

Objective To observe the effect of ultrasound-guided iliopsoas plane block(IPB)on the quality of postoperative recovery in patients undergoing hip arthroplasty.Methods Sixty patients who underwent hip arthroplasty were selected,37 males and 23 females,aged 40-79 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ.The patients were divided into two groups by random number table method:the iliopsoas plane block group(group IPB)and the femoral nerve block(FNB)group(group FNB),30 pa-tients in each group.Before anesthesia induction,IPB was performed with 0.5%ropivacaine 10 ml and lat-eral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group IPB.And FNB was performed with 0.5%ropivacaine 10 ml and lateral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group FNB.The dosages of propofol,remifentanil,and cis-atracurium during operation were recorded.The quality of recovery-15(QoR-15)scale was evaluated preoperatively and postoperatively 1 day,2 and 3 days.The max VAS(VASmax)pain score and manual muscle test(MMT)score of quadri-ceps muscle were recorded 12,24,and 48 hours after surgery.The time of getting out of bed for the first time,opioid dosage,and patient satisfaction were recorded.The incidence of nerve injury,vascular injury,puncture site infection,and local anesthetic poisoning were recorded.The postoperative complications of diz-ziness,nausea and vomiting,deep vein thromboses,and elirium were also recorded.Results There was no significant difference in the dosage of propofol,remifentanil,and cis-atracurium between the two groups.Compared with group FNB,the QoR-15 scale score in group IPB was significantly higher 1 day,2 and 3 days after operation(P＜0.05).Compared with group FNB,the MMT scores of quadriceps muscle was sig-nificantly higher in group IPB 12 and 24 hours after surgery(P＜0.05),and the first time of getting out of bed was shortened in group IPB(P＜0.05).However,there were no significant differences in the VASmax pain score,MMT score of quadriceps muscle 48 hours after surgery,opioid dosage,and patient satisfaction between the two groups.No nerve block related complications were found in both groups.There were no sig-nificant differences in postoperative complications between the two groups.Conclusion The iliopsoas plane block can improve the quality of postoperative recovery and accelerate the recovery of patients with hip re-placement,and the effect is better than that of femoral nerve block.

BACKGROUND:The effect of electroacupuncture on the proliferation and differentiation of hippocampal oligodendrocytes in model mice with Alzheimer's disease remains poorly understood while demyelinating reaction related to oligodendrocytes is a common pathological reaction of Alzheimer's disease. OBJECTIVE:To investigate the effects and mechanism of electroacupuncture stimulation of"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)in Alzheimer's disease model mice on the proliferation and differentiation of endogenous neural stem cells to neurons and oligodendrocytes. METHODS:Forty 6-week-old SPF APP/PS1 transgenic male Alzheimer's disease model mice were randomly divided into electroacupuncture group(n=20)and Alzheimer's disease model group(n=20).Healthy male C57BL/6J mice of the same age were used as normal controls(n=20).The mice in the electroacupuncture group received electroacupuncture at"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)for 16 weeks(20 minutes/day and one day off a week).After electroacupuncture,Morris water maze was used to detect the changes of learning and memory function.Immunohistochemistry was utilized to detect hippocampal dentate gyrus β-amyloid senile plaques.The expression of BrdU/NeuN and BrdU/GALC in the hippocampal dentate gyrus was detected by immunofluorescence double labeling.Western blot assay was used to detect the expression levels of neuron specific protein Nestin and oligodendrocyte specific protein GALC in the hippocampus.mRNA and protein levels of Notch1 and Hes1 in the hippocampus were detected by real-time fluorescence quantitative PCR and western blot assay. RESULTS AND CONCLUSION:(1)Compared with the normal control group,the ability of learning and memory in the Alzheimer's disease model group decreased significantly;hippocampal dentate gyrus β-amyloid senile plaques increased significantly(P<0.01);the expression of GALC and Nestin in the hippocampus decreased significantly(P<0.01,P<0.05).(2)Compared with the Alzheimer's disease model group,the learning and memory ability of the electroacupuncture group was significantly increased;β-amyloid senile plaque in the hippocampal dentate gyrus decreased significantly(P<0.01).BrdU/NeuN double labeled positive cells in the hippocampal dentate gyrus and Nestin protein expression in the hippocampus increased significantly(P<0.01,P<0.05);GALC expression in hippocampus increased significantly(P<0.01).The mRNA and protein levels of Notch1 in the hippocampus were significantly increased(P<0.05,P<0.01).The mRNA and protein levels of Hes1 in the hippocampus decreased significantly(P<0.05).(3)These findings indicate that electroacupuncture at"Baihui"(GV 20),"Fengfu"(GV 16)and bilateral"Shenshu"(BL 23)of the Alzheimer's disease model infant mice can promote the proliferation and differentiation of endogenous neural stem cells to neurons and oligodendrocytes,which may be regulated through the Notch1/Hes1 pathway.

Objective:To evaluate the safety and feasibility of the laparoscopic indocyanine green (ICG) fluorescence imaging during the sentinel node navigational surgery for the early gastric cancer.Methods:Patients with <4 cm early gastric cancer were chosen. 0.5 ml ICG (2.5 mg/ml) was preoperatively injected into submucosa around the lesion in four points by the endoscopy. The sentinel lymph node basin including the stained tissue and lymph node (LN) were completely resected guided by the fluorescence mapping under ICG laparoscopy. The specimen was inspected by frozen pathology section. The radical gastrectomy was dependent on the pathology result.Result:Between 2019 and 2021, a total of 18 patients were included in the final analysis. Most tumors (16/18) located in the middle or distal stomach. Median tumor size was 2.0 cm. Lymph vessel invasion was revealed in five cases and perineural invasion in three cases. According to AJCC tumor grading system, tumor depth was classified as Tis in 2 cases, T1a in 5 cases and T1b in 11 cases. Lymph node metastasis (LNM) was revealed in four patients (4/18, 22%). Median sentinel lymph node basins per patient were 2 (range, 1-5). An average 6 (range, 2-13) LNs were harvested in each case, including 6 (1-13) ICG stained LNs and 1 (0-5) non stained LNs. All of four LNM patients were detected by sentinel node navigational surgery. The rate of the sensitivity and accuracy were 100% and 100%, respectively. The median follow-up for the entire group was 58.3 months (0.3-59.9 months), with no recurrence or metastasis observed in any patient.Conclusion:The sensitivity and accuracy of the laparoscopic indocyanine green fluorescence imaging during the sentinel node navigational surgery were satisfactory.

Objective:To explore long-term outcome and risk factors of recurrence in stage Ⅲ gastric cancer patients who underwent radical gastrectomy and adjuvant chemotherapy.Methods:The clinical and pathological data of patients with stage Ⅲ (AJCC V8) gastric adenocarcinoma were analyzed retrospectively. All patients received radical gastrectomy and adjuvant chemotherapy consisting of oxaliplatin, fluoropyrimidines with or without docetaxel in our center during 2006 and 2011.Results:A total of 324 patients were enrolled into the study. With a median follow-up time of 108 months, 175 (54%) patients developed tumor recurrence. One hundred and eighty-three (56.5%) patients died, including 169 (52.2%) dying of gastric cancer recurrence. The median disease-free survival (DFS) was 35 months, and the median overall survival (OS) was 64 months. The 5-year OS rates were 58.2%, 51.5% and 25.6% in patients with stage ⅢA, ⅢB and ⅢC diseases, respectively ( P<0.01). Multivariate analysis revealed that T4b cancers ( P=0.02), higher lymph meta node ratio (LNR) ( P<0.01) and perineural invasion ( P=0.01) were independent negative prognostic factors, while more than 12 weeks of adjuvant chemotherapy may improve survival. Higher LNR was correlated with locoregional ( P<0.01), distant lymph node metastases ( P<0.01), and peritoneal metastases ( P=0.038). Perineural invasion ( P=0.047) was prone to peritoneal metastases. More than 12 weeks of adjuvant chemotherapy could reduce the risk of haematogenous metastases ( P=0.023). Conclusions:Outcomes were significantly different in subgroups of patients with stage Ⅲ gastric cancers after radical gastrectomy. Higher LNR and perineural invasion could predict poor prognosis and different recurrence patterns.
