The acupuncture manipulation is an important factor for achieving a good therapeutic effect in acupuncture practice.The authors review recent studies on acupuncture manipulation and its qualification from a) differences of the therapeutic effects of acupuncture manipulation,b) quantification of acupuncture manipulations,and c) instruments for delivering and sampling the analogued parameters of different acupuncture manipulations,computer analysis software,etc.Most studies revealed that different acupuncture manipulations had different clinical efficacies.Meanwhile,researches on the quantification of acupuncture manipulations and some related instruments also have made a bigger progress.Nevertheless,there still exist many problems,such as difficulties of various acupuncture techniques in unification in clinic,stronger personal subjectivity in performing manipulations,etc.We should overcome these problems and conduct more researches,so as to raise the clinical curative effect further.

ObjectiveTo investigate the effectiveness of combined oxaliplatin regimen as adjuvant chemotherapy for hepatocellular carcinoma and to evaluate the efficacy of using adenosine triphosphate tumor chemosensitivity assay (ATP-TCA) for direction of individual chemotherapy.MethodsThe twenty-six patients with primary hepatocellular carcinoma were operated.Specimens were collected and adenosine triphosphate tumor chemosensitivity assay (ATP-TCA) was applied to evaluate the sensitiveness of chemotherapy agent(Adriamycin, Mitomycin, Mitoxantrone, Oxaliplatin, Irinotecan, 5-FU, Gemzar, Carboplatin, Cisplatin, Docetaxel and Etoposide).Sensitive group (SG) was from from 11 patients who were sensitive to oxaliplatin, and control group was from the other 16 patients who were not sensitive to oxaliplatin.All the twenty-six patients received oxaliplatin combined with 5-FU or capecitabine regimen chemotherapy.The effectiveness (CR,PR,SD,PD,ORR,OS and DFS) of the regimen according to RECIST criteria and WHO criteria for anticancer drugs toxicity and efficacy of ATP-TCA were evaluated.ResultsTwenty-six patients were successfully evaluated.In SG, six patients obtained complete remission(CR), three got partial remission(PR), one got stable disease (SD) and one patient got progression disease (PD).While in control group,four patients obtained CR,two patients got PR, five patients got SD and four got PD.No significant differences were found in overall survival (OS, P = 0.1116) and disease-free survival (DFS, P = 0.2328)between sensitive group and control group.But significant differences were found in overall response rate (ORR) (81.8％ vs 40.0％, P =0.0401) between two groups.Common toxicities were as follows:I to Ⅱdegree of myelosuppression was 53.8％, I to Ⅱ degree of gastrointestinal tract response was 50％, I to Ⅱ degree of liver function damage was 57.7％ and I to Ⅱ degree of neuropathy was 23.1％, respectively.Most of these toxicities were tolerable at grade 1 ～ 2.No significant differences were found in the toxicities between two groups.ConclusionsCombined oxaliplatin regimen might be an effective choice for adjuvant chemotherapy for HCC, which has with tolerable systemic toxicity.Application of ATP-TCA system might further improve the efficacy of this regimen by selecting right candidate.

Objective To investigate the expression of multidrug resistance protein such as multidrug resistance-associated protein 1 (MRP1),lung-resistance related protein (LRP), P-glycoprotein (Pgp),glutathione s-transferase (GST-π) and topoismerase Ⅱ (TOPO Ⅱ ) in hepatocellular carcinoma (HCC), which would be supplied for the clinical chemotherapy of HCC. Methods Twenty-six cases of HCC who underwent hepatectomy were enrolled and immunohistochemical (IHC) staining was carried out on all specimens for the detection of expression of MRP1,LRP,Pgp,GST-πand TOPO Ⅱ and the data was analyzed by image analysis system. Results The expression of five multidrug resistance protein in HCC tissue were significantly higher than those in adjacent tissue beyond cancer (P ＜0.05). The significant differences were found in the expression of Pgp,TOPO Ⅱ and GST-π between HCC tissue and distant metastasis (P ＜ 0.05 ). The expression of the five multidrug resistance protein in poorly differentiated HCC tissue was higher than that in well-differentiated tissue,while the significant difference was only found in the expression of TOPO Ⅱ (P ＜ 0.05 ). The significant association was not found between the expressions of five multidrug resistance protein in HCC tissue and the size of tumor,AFP, the portal vein tumor thrombus,hepatic cirrhosis and liver function. Conclusions Five multidrug resistance protein overexpression in various degrees in HCC tissue, which relates to some biological behavior of the cancer. Combined detection is of much benefit to the choice of the drug of chemotherapy and to the prediction of prognosis.

Objective:To explore the effect of plastic surgery suture technique and its proficiency in facial scar inhibition after trauma, and to explore the key factors to improve the suture proficiency of junior residents.Methods:The data of patients with facial trauma who underwent plastic surgery suture in the Department of Plastic and Reconstructive Surgery of Ningbo First Hospital from June 2017 to July 2019 were retrospectively analyzed. They were divided into senior group and junior group according to the seniority of chief surgeon. The general condition, scar appearance and local symptoms of the two groups were evaluated by the scar cosmesis assessment and rating scale(SCAR), including scar expansion, erythema, hyperpigmentation or hypopigmentation, suture marks, hyperplasia or atrophy, scar pruritus, scar pain, and the results were statistically analyzed.The mean of continuous data were calculated and expressed as Mean ± SD, the differences between groups were tested by t-test, and the classified data were expressed by rate, and the differences between groups were tested by chi-square test. Results:A total of 83 patients (54 females and 29 males) were included in this study, the maximum age was 63, the minimum age was 3, and the average age was 31.7±13.3 years old, including senior group (52 cases) and junior group (31 cases). The differences were not statistically significant in gender, age, injury time, wound length and complications between the two groups. The total scores of SCAR scale in the senior and junior groups were 2.18±0.98 and 2.78±1.30, respectively, the difference was statistically significant ( P=0.020). The senior group was better than the junior group in inhibiting scar expansion ( P=0.035), eliminating suture marks ( P=0.018), overall scar impression ( P=0.038) and reducing pigment abnormality ( P=0.045). However, in inhibiting erythema and inhibiting scar hyperplasia or atrophy, the differences were not statistically significant between two groups. In the senior group, 4 patients had pain within 24 hours, 3 patients had pruritus; in the junior group, 2 patients had pain, 3 patients had pruritus. Conclusions:Plastic surgery suture technique will effectively improve the appearance of facial scar after trauma, especially in inhibiting scar expansion, erythema, hyperplasia or atrophy, and overall impression.Junior doctors can be competent for this work to a certain extent, but thay need long-term training to master the technology, and skilled operation can further improve the curative effect.

To investigate the clinical efficacy of one-stage repairing the wounds after excision of soft tissue malignant tumor in lower limb with deep inferior epigastric perforator (DIEP) flaps. Methods From Au-gust, 2016 to July, 2018, 11 patients(8 males and 3 females; aged 35-76 years) with the soft tissue defects in the low-er limb underwent immediate reconstructive operations with DIEP flap after their tumor resection. The defects ranged in area from 11 cm×7 cm to 25 cm×10 cm after extended resection, including 5 cases of bone exposure. The DIEP flap area ranged from 11 cm×8 cm to 26 cm×18 cm.Among them, 9 cases were treated with free transplantation and 2 cases with pedicle transplantation.The donor sites were closed directly. The patients’ limb function, tumor recurrence and the healing of surgical incision had been followed-up. Results Eleven flaps survived and the donor sites healed directly. One flap had skin pigmentation due to postoperative vascular crisis, and the other flaps had satisfied texture and appearance. All patients were followed-up from 6 to 30 months. The lower limb movement was normal. All the donor sites had a good healing with no pain and abdominal complications. No tumor recurrence was observed during the followed-up period. Conclusion DIEP flap have many advantages, such as large cutting area, which is suitable for large-area wound repair after extended excision of soft tissue malignant tumor in lower limb. At the same time, the perforator vessel is constant and the caliber are thick, also the donor area is concealed and can be sutured directly.This kind of the technique for reconstruction of lower limb soft tissue defects after malignant tumor resection is well acceptable.

The clinicopathological data of 242 gastric cancer patients who underwent laparoscopic radical gastrectomy in 19 hospitals of the Chinese Laparoscopic Gastrointestinal Surgery Study Group-04 study, including 54 patients in Fujian Medical University Union Hospital, 32 patients in the First Hospital of Putian City, 32 patients in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, 31 patients in Zhangzhou Affiliated Hospital of Fujian Medical University, 17 patients in Nanfang Hospital of Southern Medical University, 11 patients in the First Affiliated Hospital with Nanjing Medical University, 8 patients in Qinghai University Affiliated Hospital, 8 patients in Meizhou People′s Hospital, 7 patients in Fujian Provincial Hospital, 6 patients in Zhongshan Hospital of Fudan University, 6 patients in Longyan First Hospital, 5 patients in the First Affiliated Hospital of Xinjiang Medical University, 5 patients in the First Hospital Affiliated to Army Medical University, 4 patients in the Second Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, 4 patients in West China Hospital of Sichuan University, 4 patients in Beijing University Cancer Hospital, 3 patients in the First Affiliated Hospital of Xiamen University, 3 patients in Guangdong Provincial People′s Hospital, 2 patients in the First Affiliated Hospital of Xi′an Jiaotong University, from September 2016 to October 2017 were collected. There were 193 males and 49 females, aged 62(range, 23?74)years. Observation indicators: (1) age distribution, comorbidities and ACCI status of patients; (2) the grouping of ACCI and comparison of clinicopathological characteristics of patients in each group; (3) incidence of postoperative early complications and analysis of factors affecting postoperative early complications; (4) follow-up; (5) analysis of factors affecting the 3-year recurrence-free survival rate of patients. Follow-up was conducted using outpatient examination or telephone interview to detect postoperative survival of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the nonparametric rank sum test. The X-Tile software (version 3.6.1) was used to analyze the best ACCI grouping threshold. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-Rank test was used for survival analysis. The Logistic regression model was used to analyze the factors affecting postoperative early complications. The COX proportional hazard model was used for univariate and multivariate analyses of factors affecting the 3-year recurrence-free survival rate of patients. Multivariate analysis used stepwise regression to include variables with P<0.05 in univariate analysis and variables clinically closely related to prognosis. Results:(1) Age distribution, comor-bidities and ACCI status of patients. Of the 242 patients, there were 28 cases with age <50 years, 68 cases with age of 50 to 59 years, 113 cases with age of 60 to 69 years, 33 cases with age of 70 to 79 years. There was 1 patient combined with mild liver disease, 1 patient combined with diabetes of end-organ damage, 2 patients combined with peripheral vascular diseases, 2 patients combined with peptic ulcer, 6 patients combined with congestive heart failure, 8 patients combined with chronic pulmonary diseases, 9 patients with diabetes without end-organ damage. The ACCI of 242 patients was 2 (range, 0-4). (2) The grouping of ACCI and comparison of clinicopathological characteristics of patients in each group. Results of X-Tile software analysis showed that ACCI=3 was the best grouping threshold. Of the 242 patients, 194 cases with ACCI <3 were set as the low ACCI group and 48 cases with ACCI ≥3 were set as the high ACCI group, respectively. Age, body mass index, cases with preoperative comorbidities, cases of American Society of Anesthesiologists classification as stage Ⅰ, stage Ⅱ, stage Ⅲ, tumor diameter, cases with tumor histological type as signet ring cell or poorly differentiated adenocarcinoma and cases with tumor type as moderately or well differentiated adenocarcinoma, cases with tumor pathological T staging as stage T1, stage T2, stage T3, stage T4, chemotherapy cycles were (58±9)years, (22.6±2.9)kg/m 2, 31, 106, 85, 3, (4.0±1.9)cm, 104, 90, 16, 29, 72, 77, 6(4,6) in the low ACCI group, versus (70±4) years, (21.7±2.7)kg/m 2, 23, 14, 33, 1, (5.4±3.1)cm, 36, 12, 3, 4, 13, 28, 4(2,5) in the high ACCI group, showing significant differences in the above indicators between the two groups ( t=-14.37, 1.98, χ2=22.64, Z=-3.11, t=-2.91, χ2=7.22, Z=-2.21, -3.61, P<0.05). (3) Incidence of postoperative early complications and analysis of factors affecting postoperative early complications. Of the 242 patients, 33 cases had postoperative early complications, including 20 cases with local complications and 16 cases with systemic complica-tions. Some patients had multiple complications at the same time. Of the 20 patients with local complications, 12 cases had abdominal infection, 7 cases had anastomotic leakage, 2 cases had incision infection, 2 cases had abdominal hemorrhage, 2 cases had anastomotic hemorrhage and 1 case had lymphatic leakage. Of the 16 patients with systemic complications, 11 cases had pulmonary infection, 2 cases had arrhythmias, 2 cases had sepsis, 1 case had liver failure, 1 case had renal failure, 1 case had pulmonary embolism, 1 case had deep vein thrombosis, 1 case had urinary infection and 1 case had urine retention. Of the 33 cases with postoperative early complications, there were 3 cases with grade Ⅰ complications, 22 cases with grade Ⅱ complications, 5 cases with grade Ⅲa complications, 2 cases with grade Ⅲb complications and 1 case with grade Ⅳ complica-tions of Clavien-Dindo classification. Cases with postoperative early complications, cases with local complications, cases with systemic complications were 22, 13, 9 in the low ACCI group, versus 11, 7, 7 in the high ACCI group, respectively. There were significant differences in cases with postoperative early complications and cases with systemic complications between the two groups ( χ2=4.38, 4.66, P<0.05), and there was no significant difference in cases with local complications between the two groups ( χ2=2.20, P>0.05). Results of Logistic regression analysis showed that ACCI was a related factor for postoperative early complications of gastric cancer patients undergoing laparoscopic radical gastrectomy [ odds ratio=2.32, 95% confidence interval ( CI) as 1.04-5.21, P<0.05]. (4) Follow-up. All the 242 patients were followed up for 36(range,1?46)months. During the follow-up, 53 patients died and 13 patients survived with tumor. The 3-year recurrence-free survival rate of the 242 patients was 73.5%. The follow-up time, cases died and cases survived with tumor during follow-up, the 3-year recurrence-free survival rate were 36(range, 2-46)months, 29, 10, 80.0% for the low ACCI group, versus 35(range, 1-42)months, 24, 3, 47.4% for the high ACCI group. There was a significant difference in the 3-year recurrence-free survival rate between the two groups ( χ2=30.49, P<0.05). (5) Analysis of factors affecting the 3-year recurrence-free survival rate of patients. Results of univariate analysis showed that preoperative comorbidities, ACCI, tumor diameter, histological type, vascular invasion, lymphatic invasion, neural invasion, tumor pathological TNM staging, postoperative early complications were related factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy [ hazard ratio ( HR)=2.52, 3.64, 2.62, 0.47, 2.87, 1.90, 1.86, 21.77, 1.97, 95% CI as 1.52-4.17, 2.22-5.95, 1.54-4.46, 0.27-0.80, 1.76-4.70, 1.15-3.12, 1.10-3.14, 3.01-157.52, 1.11-3.50, P<0.05]. Results of multivariate analysis showed that ACCI, tumor pathological TNM staging, adjuvant chemotherapy were indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy ( HR=3.65, 11.00, 40.66, 0.39, 95% CI as 2.21-6.02, 1.40-86.73, 5.41-305.69, 0.22-0.68, P<0.05). Conclusions:ACCI is a related factor for post-operative early complications of gastric cancer patients undergoing laparos-copic radical gastrectomy. ACCI, tumor pathological TNM staging, adjuvant chemotherapy are indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy.
