Objective To evaluate the effects of transcutaneous electrical acupoint stimulation(TEAS)combined with Chinese medicine emotional intervention on immune function and psychological stress in patients undergoing laparoscopic radical rectal cancer surgery.Methods A total of 100 patients hospitalized for laparoscopic radical surgery for rectal cancer were randomly divided into 4 groups of Group A,B,C,and D,25 patients in each group.Group A was given TEAS for 30 minutes before anesthesia,Group B was given TEAS continuously until the end of the surgery,Group C was given TEAS for 30 minutes and Chinese medicine emotional intervention before anesthesia,Group D was given TEAS continuously until the end of the surgery together with Chinese medicine emotional intervention.TEAS was performed at bilateral Zusanli(ST36)points,bilateral Sanyinjiao(SP6)points,Baihui(GV20)points,bilateral Neiguan(PC6)points.The changes of perioperative outcomes and the changes of parameters associated with the immune function,molecular mechanism of Th1/Th2 cells,and psychological stress response before the surgery and 3 days after the surgery in each group were observed.Moreover,the occurrence of adverse reactions in each group was compared.Results(1)The differences of perioperative outcomes operation time,bleeding volume and infusion amount were not statistically significant among the 4 groups(P＞0.05).The Sufentanil dosage,Remifentanil dosage,postoperative awakening time,and 24-hour postoperative pain Visual Analogue Scale(VAS)scores of group D were lower than those of Groups A,B,and C(P＜0.05),and the above indexes of group B and group C were all lower than those of Group A(P＜0.05).(2)Three days after the surgery,the levels of immune function indicators of T lymphocyte subsets CD3+,CD4+ and natural killer(NK)cells in Group D were higher than those in Groups A,B,and C(P＜0.05),while the above indexes in Groups B and C were higher than those in Group A(P＜0.05).(3)Three days after the surgery,the levels of parameters associated with the molecular mechanism of Th1/Th2 cells such as interleukin 2(IL-2)and interferon gamma(IFN-γ)in Group D were higher(P＜0.05),and the serum interleukin 10(IL-10)level was lower than those in Groups A,B,and C(P＜0.05);the serum IL-2 and IFN-γ levels in Group B and C were higher(P＜0.05)and serum IL-10 level was lower than those in Group A(P＜0.05).(4)Three days after the surgery,the scores of the psychological stress response indicators of self-rating anxiety scale(SAS)and self-rating depression scale(SDS)in Group D were lower than those in Groups A,B,and C(P＜0.05),while the above scores in Groups B and C were lower than those in Group A(P＜0.05).(5)In Group A,there was one case of nausea and vomiting;in Group B,there were two cases of nausea and vomiting and one case of dizziness;no adverse reaction occurred in Group C,and there was one case of nausea and vomiting in Group D.The incidences of adverse reactions in Groups A,B,C and D were 4.0%(1/25),12.0%(3/25),0.0%(0/25),and 4.0%(1/25),respectively.The intergroup comparison showed no statistically significant difference among the 4 groups(χ2 = 0.400,P = 0.527).Conclusion In treating patients undergoing laparoscopic radical surgery for rectal cancer,TEAS combined with Chinese medicine emotional intervention can effectively regulate the perioperative immune function,reduce the stress response,and alleviate the anxiety of the patients.Moreover,the therapy exerts certain analgesic effect,which leads to the reduction of the dosage of opioids and the increase of perioperative comfort and surgical tolerance of the patients.

The Clinical Application Value of Modified Laparoscopic Radical Surgery with-out Uterine Manipulator in Early Cervical Cancer / 实用妇产科杂志

Objective:To explore the clinical value of modified laparoscopic radical surgery without uterine ma-nipulator in the treatment of early cervical cancer.Methods:A retrospective analysis was conducted on the clinical data of 105 patients with early cervical cancer(stages ⅠB1,ⅠB2,ⅡA1)who underwent radical resection of cer-vical cancer in West China Second University Hospital,Sichuan University from January 2019 to January 2020.According to the operation methods,the patients were divided into uterine lifter-free group(35 cases),uterine lifter group(35 cases)and laparotomy group(35 cases).The operation duration,intraoperative blood loss,number of resected lymph nodes,postoperative anal exhaust time,drainage tube placement time,hospitalization time,inci-dence of surgical complications,recurrence rate and mortality rate were compared among the three groups.Re-sults:There was no statistically significant difference in the number of lymph node resection,the postoperative anal exhaust time,drainage tube placement time and hospitalization time among the three groups(P>0.05).Comparison between two groups showed that the operation time of the group without uterine lifting was longer than that of the laparotomy group,and the intraoperative bleeding volume and the Postoperative anal exhaust time of the laparotomy group were more than those of the other two groups,and the differences were statistically signif-icant(P<0.05).There were 18 cases of surgical complications in the three groups.The incidence rate of uterine lifter-free group,laparotomy group and uterine lifter group was 11.4%,20.0%and 20.0%,respectively,with no statistically significant difference(P>0.05).There were 8 patients with recurrence 2 years after operation,the re-currence rates of the uterine lifter-free group,the laparotomy group and the uterine lifter group were 0,5.7%and 17.1%,respectively,the difference was statistically significant(P<0.05).The recurrence rate of the group with-out uterine lifting was significantly lower than that of the uterine lifting group(P<0.05).There were0 death in the non-lifting group,0 in the laparotomy group,and 1 case in the uterine lifting device group within 2 years after oper-ation,the difference was no statistically significant(P>0.05).Conclusions:The modified laparoscopic radical re-section without uterine lifter can reduce the risk of tumor recurrence in laparoscopic radical resection with uterine lifter,which is equivalent to the treatment effect of open surgery,and does not increase the risk of surgical compli-cations.It has clinical application value.

Techniques of identifying parathyroid glands and their related clinical research progress / 西安交通大学学报(医学版)

Parathyroid glands play an important role in calcium and phosphorus metabolism in human beings.The complete preservation of parathyroid glands during neck surgery is crucial in avoiding postoperative hypoparathyroidism and hypocalcemia.At present,most thyroid operations still rely on traditional visual identification or intraoperative freezing to identify parathyroid glands.The former depends on the experience of the surgeon,while the latter needs longer time and costs much.Recently,researchers have conducted relevant studies on intraoperative staining techniques and fluorescent-based imaging techniques that are helpful for the identification of parathyroid glands,such as methylene blue,carbon nanoparticles suspension,near-infrared autofluorescence,indocyanine green angiography,and laser speckle contrast imaging.The above-mentioned techniques all have significantly improved the identification and protection of parathyroid glands.This article reviews the progress in clinical research on intraoperative identification of parathyroid glands.

Meta-analysis of clinical value of adjuvant radiotherapy versus surgery alone in the treatment of stage pT 2-3N 0M 0 esophageal squamous cell carcinoma / 中华放射肿瘤学杂志

Objective:To compare the efficacy and safety of adjuvant radiotherapy versus surgery alone in patients with stage pT 2-3N 0M 0 esophageal squamous cell carcinoma after radical resection. Methods:The search was conducted through Web of Science, Emabse, PubMed, Cochrane Library, CNKI, Chongqing VIP, China Biomedical Literature Database, and Wanfang database, etc. The search time was ranged from the establishment of the database to December 2022. Searched studies were screened according to the inclusion and exclusion criteria. Review Manager 5.4 software was used for analysis.Results:Clinical data of 2 424 patients from 8 controlled clinical studies were finally included. Meta-analysis showed that postoperative adjuvant radiotherapy had higher 3-year and 5-year disease-free survival rates ( OR=2.33, 95%CI=1.71-3.17, P<0.001; OR=2.38, 95% CI=1.73-3.27, P<0.001) and 3-year and 5-year overall survival rates ( OR=1.89, 95% CI=1.37-2.60, P<0.01; OR=1.94,95% CI=1.50-2.49, P<0.001) than surgery alone. Meanwhile, the local recurrence rate ( OR=0.33, 95% CI=0.21-0.50, P<0.001) and distant metastasis rate ( OR=0.62, 95% CI=0.39-0.98, P=0.040) of postoperative adjuvant radiotherapy group were lower than those in the surgery alone group. The incidence of radiation esophagitis (1.4%-9.5%), radiation pneumonitis (2.1%) and anastomotic stenosis (5.3%) was reported. Conclusions:For patients with stage pT 2-3N 0M 0 squamous cell carcinoma after radical resection of esophageal cancer, adjuvant radiotherapy may improve 3-year and 5-year disease-free survival rates and 3-year and 5-year overall survival rates compared with surgery alone. In addition, adjuvant radiotherapy may reduce the local recurrence and distant metastasis rates. Therefore, postoperative adjuvant radiotherapy is an optional treatment for stage pT 2-3N 0M 0 esophageal squamous cell carcinoma.

Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

Clinical features and optimal treatment of primary urethral carcinoma / 现代泌尿外科杂志

【Objective】 To explore the clinical features and treatment outcomes of female urethral carcinoma so as to improve the awareness and prognosis of this rare malignant disease. 【Methods】 Clinical data of 8 cases of female urethral carcinoma treated during Jan. 2012 to Dec.2022 at the Department of Urology of Peking University People’s Hospital were retrospectively analyzed. The patients underwent urodynamic tests, cystourethroscopy and pathological biopsy to confirm the diagnosis. Traditional radical surgery was performed in 5 cases, and radical surgery for lower urethral cancer with bladder preservation was performed in 3 cases. 【Results】 The patients aged 36 to 68 years, with a mean of 53.75 years. Urinary obstruction, lower urinary tract symptoms and urethral masses were common manifestations. Urodynamic tests indicated bladder outlet obstruction. After surgical treatment, radical surgery for lower urethral cancer with bladder preservation showed advantages over traditional radical surgery in terms of intraoperative bleeding, operation time and postoperative hospital stay. 【Conclusion】 Female primary urethral carcinoma is rare but invasive. Early diagnosis and radical surgery are crucial for improving the prognosis. Radical surgery for lower urethral cancer with bladder preservation has better treatment outcomes and postoperative quality of life compared to traditional radical surgery. For such patients, symptoms should be closely monitored and timely diagnosis and treatment should be performed.

Clinical application of optical surface monitoring system in radiotherapy after radical mastectomy for left breast cancer / 中国辐射卫生

@#<b>Objective</b> To study the setup error under deep inspiration breath hold (DIBH) guided by optical surface monitoring system (OSMS) and free breathing (FB) FB1 and FB2 (without OSMS guidance, directly set up the body marker line by laser lamp) in radiotherapy after radical mastectomy for left breast cancer, and to provide a basis for individualized clinical target volume-planning target volume (CTV-PTV) expansion for the doctor in charge to delineate the target volume. <b>Methods</b> A total of 36 patients with left breast cancer after radical mastectomy were selected and divided into three groups, in which cone beam computed tomography (CBCT) images were taken in three states: DIBH, FB1, and FB2, respectively. CBCT and CT images were analyzed for registration; the absolute error data of linear displacement in the ventro-dorsal, cranio-caudal, and left-right directions were recorded, and the expanding margin was calculated. <b>Results</b> The translation errors in the ventro-dorsal, cranio-caudal, and left-right directions were (0.06 ± 0.22) cm, (0.05 ± 0.23) cm, and (0.01 ± 0.24) cm in the DIBH group, (0.07 ± 0.21) cm, (0.02 ± 0.23) cm, and (0.02 ± 0.21) cm in the FB1 group, and (0.07 ± 0.24) cm, (0.07 ± 0.34) cm, and (0.25 ± 0.09) cm in the FB2 group. The statistical results of the DIBH group and FB1 group in the ventro-dorsal, RTN, and ROLL directions were significantly different (<i>P</i> < 0.05). The statistical results of the FB1 group and FB2 group in the ventro-dorsal direction were significantly different. The relation of three groups in the value of margin of planning target volume was DIBH < FB1 < FB2 in the ventro-dorsal and cranio-caudal directions and FB1 < DIBH < FB2 in the left-right direction. <b>Conclusion</b> OSMS-guided DIBH radiotherapy in patients with left breast cancer after radical mastectomy can reduce the setup error and provide an important basis for individualized CTV-PTV expansion for the doctor in charge to delineate the target volume.

Construction and evaluation of a predictive nomogram model for the prognosis of intrahepatic cholangiocarcinoma patients undergoing curative resection based on the albumin-bilirubin score and tumor burden score grade / 中华肝胆外科杂志

Objective:A predictive nomogram model for the prognosis of intrahepatic cholangiocarcinoma (ICC) patients after curative resection was constructed based on the albumin-bilirubin score and tumor burden score (ATS) grade, and the predictive performance of the nomogram model was evaluated.Methods:Retrospective analysis of clinical data was made, from ICC patients who underwent curative resection at Zhengzhou University People's Hospital and Zhengzhou University Cancer Hospital from January 2016 to January 2020. A total of 258 patients were included in the study, with 140 males and 118 females, with an average age of (56.5±9.5) years. The 258 ICC patients were randomly divided into a training set ( n=174) and a testing set ( n=84) in a 7∶3 ratio. Single-factor and multi-factor Cox regression analyses were performed to identify prognostic factors for ICC patients of the training set, and then a nomogram model was constructed. The performance of the nomogram model was evaluated by using the concordance index (C-index), calibration curve, and risky decision curve analysis. Results:In the training set, univariate Cox regression analysis indicated that albumin-bilirubin (ALBI), tumor burden score (TBS), carcinoembryonic antigen (CEA), tumor differentitation, lymphvascular invasion and ATS significantly influenced overall survival after radical resection for ICC (all P<0.05). Multifactorial Cox regression analysis revealed that ATS grade, CEA, tumor differentiation, lymphovascular invasion, and AJCC N stage are independent risk factors for the prognosis of ICC patients after curative resection (all P<0.05). Assessment of the postoperative survival prediction model based on multifactorial Cox regression yielded a C-index of 0.775(95% CI: 0.747-0.841) for the training set and 0.731(95% CI: 0.668-0.828) for the testing set. The calibration curves for both the training and testing sets indicated strong predictive capability of the model. Additionally, the risk decision curve also suggested high net benefit of the model. Conclusions:The preoperative ATS grade is an independent factor affecting the survival after ICC radical resection. The nomogram model constructed based on ATS grade demonstrates excellent predictive value for postoperative prognosis in ICC patients.

Influencing factors of anxiety and depression in patients with secondary lower extremity deep venous thrombosis after radical cervical cancer surgery / 中华健康管理学杂志

Objective:To investigate the influencing factors of anxiety and depression in patients with secondary lower extremity deep venous thrombosis (LEDVT) after radical cervical cancer surgery.Methods:Retrospective analysis method was used, a total of 92 patients with anxiety and/or depression secondary to LEDVT after radical cervical cancer surgery admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from June 2019 to June 2022 were included as the observation group, according to the presence of anxiety or depression, they were divided into anxiety group (65 cases) and depression group (58 cases) (some patients had both anxiety and depression). Another 90 patients who did not have anxiety or depression after radical cervical cancer surgery with secondary LEDVT were selected as the control group in the same period. The questionnaires of clinical data and disease cognition were designed to investigate the clinical data and disease cognition of patients, social support rating scale (SSRS) was used to assess the level of social support of patients, and univariate analysis was performed to identify the influencing factors of depression and anxiety in patients with secondary LEDVT after radical cervical cancer surgery.Results:The percentage of patients with self-pay, no children, unemployed or jobless, monthly family income <5 000 CNY, less social support, and disease awareness <80 scores in the anxiety group and depression group (36.92%, 67.69%, 69.23%, 66.15%, 46.15%, 70.77% and 34.48%, 68.97%, 72.41%, 65.52%, 44.83%, 68.97%) were higher than the control group (14.44%, 40.00%, 33.33%, 32.22%, 11.11%, 23.33%) (all P<0.01). The percentage of mixed thrombus, central thrombus, peripheral thrombus, bilateral thrombus, right thrombus, and left thrombus in the anxiety group and depression group (30.77%, 20.00%, 49.23%, 16.92%, 35.38%, 47.69% and 32.76%, 15.52%, 51.72%, 12.07%, 37.93%, 50.00%) were not significantly different from those in the control group (32.22%, 17.78%, 50.00%, 10.00%, 36.67%, 53.33%) (all P>0.05). Univariate analysis showed that self-pay, unemployed or jobless, no children, monthly family income <5 000 CNY, less social support, and disease awareness <80 scores were correlated with depression and anxiety status in patients with secondary LEDVT after radical cervical cancer surgery (all P<0.01). Conclusion:Depression and anxiety in patients with secondary LEDVT after radical cervical cancer surgery are related to self-pay, unemployed or jobless, no children, low monthly family income, less social support, and low disease awareness.

No hubo diferencias estadísticamente significativas entre ambos grupos en cuanto a la recurrencia tumoral o las tasas de supervivencia. De 25 pacientes operadas para preservación de la fertilidad 18 de 25 intentaron quedar embarazadas. Se registraron 15 de 18 embarazos, incluidos 13 nacidos vivos, 1 aborto espontáneo y 1 muerte fetal intrauterina. CONCLUSIÓN: La cirugía conservadora de la fertilidad podría ser una alternativa adecuada a la cirugía radical para mujeres jóvenes con cáncer epitelial de ovario en estadio I.

Abstract OBJECTIVE: In the current study, we aimed to compare between radical surgery and fertility saving surgery in females with stage 1A-C EOC regarding recurrence rate and patients survival rates in addition to evaluating reproductive and obstetric outcomes for stage I EOC females who were managed by fertility saving surgery. PATIENTS AND METHODS: We prospectively identified 60 patients diagnosed with stage I EOC aged ≤ 40 years. Patients in the fertility-preservation group underwent salpingo-oophorectomy on the side of the affected ovary in addition to incisional biopsy or wedge excision of the ovary on the other side. Patients in the radical surgery group underwent total hysterectomy and bilateral salpingo-oophorectomy. We followed up all patients for 5 years to assess their reproductive and oncological outcomes. RESULTS: Patients in the fertility preservation surgery group were significantly younger (30 ± 4 versus 35 ± 5) (p < 0.001), their tumor sizes were smaller 3.4 ± 1.3 versus 6.0 ± 2.6 (p < 0.001), of lower grade (p = 0.011), earlier stage (p < 0.001) and has more mucinous histology than patients in the radical surgery group. There were no statistically significant differences between both groups regarding tumor recurrence or survival rates. Of 25 patients underwent fertility preservation surgery, 18/25 (72%) tried to get pregnant. 15/18 (83%) pregnancies were recorded, including 13 live births, 1 miscarriage, and 1 intrauterine fetal death. CONCLUSION: Fertility sparing surgery could be adequate alternative to radical surgery for young females with stage I EOC.

da Vinci robot system for radical surgery of lung cancer in elderly patients / 中国胸心血管外科临床杂志

@#Objective    To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods    We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results    There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion    The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.

Multiple primary carcinoma of esophagus and lung: A case report / 中国胸心血管外科临床杂志

@#Nowadays, the popularization of endoscopic technology makes a substantial increase in the diagnosis rate of esophageal multiple primary carcinoma. However, the multiple primary carcinoma combined with esophageal cancer, lung cancer and cardiac cancer is relatively rare. This paper reported a 64-year-old male with multiple primary cancer who received one-stage complex radical surgery, including radical resection of esophageal cancer, lung cancer and cardiac cancer. After the operation, the patient presented chylothorax and conservative treatment was ineffective. Then we preformed ligation of thoracic duct through single-portal thoracoscope. The patient recovered successfully after surgery and the follow-up results showed well.

Application Value of ctDNA-based MRD Dedection in Early Stage Non-small Cell Lung Cancer after Radical Surgery / 中国肺癌杂志

Lung cancer is the most common malignant tumor in the world, among which non-small cell lung cancer (NSCLC) accounts for about 85% of the total number of lung cancers. The 5-year overall survial (OS) of radical surgery NSCLC patients ranged from 92% in stage Ia1 to 26% in stage IIIb, and the continuously decreasing survival time made it a strong clinical need for precise adjuvant therapy to eradicate molecular residual disease (MRD). At present, circulating tumor DNA (ctDNA) as a molecular indicator of MRD has gradually moved from the laboratory to the clinic. The latest consensus proposes that ctDNA with abundance ≥0.02% can be stably detected in the peripheral blood of perioperative NSCLC patients, which is based on the possibility of ctDNA as an MRD indicator. MRD detection technology supports the possibility of monitoring after radical treatment of NSCLC, and ctDNA can predict the recurrence of the disease earlier than the imaging monitoring after treatment of NSCLC, providing valuable time for timely adjustment of adjuvant therapy. In the studies on early postoperative adjuvant therapy of NSCLC, different guidelines differ on whether appropriate adjuvant therapy should be carried out, while MRD can be used as a more accurate predictor to guide postoperative adjuvant therapy, so that patients can benefit from the disease treatment.

Laparoscopic precise positioning for radical prostatectomy or bladder cancer reducing the risk of delayed recovery / 解剖学报

Objective To analyze the risk factors of delayed recovery after laparoscopic prostate or bladder cancer radical surgery, and to provide information for early clinical prevention. Methods Three hundred and twenty-two cases of patients who underwent laparoscopic radical prostatectomy or bladder cancer surgery from September 2016 to January 2019 were enrolled in this study. The clinical data and surgical data of the patients were collected, the incidence of postoperative recovery delay was counted, and the risk factors of delayed recovery were analyzed by Logistic regression analysis. Results Six-noe cases of delayed recovery of laparoscopic prostate or bladder cancer were detected, the incidence rate was 18.1% (61/327) ; Univariate analysis found that delayed laparoscopic recovery of prostate or bladder cancer after radical surgery and age, combined with coronary heart disease, diabetes, respiratory disease, anemia, smoking, alcohol consumption, American Society of Anesthesiologists (ASA) classification, anesthesia time, intraoperative infusion, location clarity of anatomical landmarks were related. There was a correlation between the total amount, combined epidural anesthesia and intraoperative blood transfusion (P<0.05). Multivariate logistic regression analysis found that the age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion were independent risk factors for delayed recovery after laparoscopic prostate cancer or radical surgery for bladder cancer (P<0.05). Conclusion There is correlation between delayed laparoscopic recovery of prostate cancer or bladder cancer after radical operation and age, diabetes, respiratory disease, anemia, smoking, alcohol consumption, location clarity of anatomical landmarks and intraoperative total infusion. Accurate anatomical location can reduce the risk of postoperative recovery delay. It is conducive to the recovery of the patients after operation, and the corresponding hospitalization time of the patients is greatly shortened.

Comparison of oxycodone with sufentanil in transition analgesia after radical surgery of cervical cancer / 西安交通大学学报(医学版)

【Objective】 To compare the efficacy and safety of oxycodone and sufentanil in transition analgesia after radical surgery of cervical cancer under general anesthesia. 【Methods】 A randomized, double-blind study was conducted. We randomly divided 68 patients on radical surgery of cervical cancer under general anesthesia into two groups: Group S (sufentanil in transition analgesia) (n=35) and Group O (oxycodone in transition analgesia) (n=33). Patients in Group S received sufentanil (0.1 μg/kg for endoscopy procedures or 0.15 μg/kg for laparotomy procedures), whereas patients in Group O received oxycodone (0.1 mg/kg for endoscopy procedures or 0.15 mg/kg for laparotomy procedures) 30 min before the end of operation as transition analgesia. We recorded the time of consciousness recovery and extubation, RSS restlessness score, the number of cough times, Ramsay score, Numerical Rating Scale (NRS) at rest in extubation immediately (T0), 30 min after extubation (T1), 1 h after extubation (T2), 2 h after extubation (T3), 4 h after extubation (T4), 12 h after surgery (T5), 24 h after surgery (T6), and the incidence of adverse complications within 24 h after operation. 【Results】 Compared with those in Group S, patients in Group O showed shorter time of consciousness recovery (4.28±3.35 vs. 5.53±2.25, P=0.027), shorter time of extubation (5.92±3.67 vs. 8.09±2.49, P=0.001), lower RSS restlessness score (0.38±0.49 vs. 0.83±0.63, P<0.001), smaller number of cough times (0.96±0.78 vs. 1.34±0.93, P=0.026), lower Ramsay score (2.3±0.58 vs. 2.63±0.85, P=0.017), and lower NRS score at rest in T3 and T4 (2.64±0.63 vs. 3.14±0.66; 2.86±0.81 vs. 3.69±0.75) (P<0.001). The incidence of nausea and vomiting was lower in Group O than in Group S (9.09% vs. 20%; 3.03% vs. 11.43%). 【Conclusion】 Both oxycodone and sufentanil provide adequate pain relief in transitional analgesia after radical surgery of cervical cancer under general anesthesia. However, oxycodone shows longer analgesia, faster recovery, and a lower incidence of side effects than sufentanil.

Concept and clinical application of surgical margin principle on head and neck cancers / 中华耳鼻咽喉头颈外科杂志

Surgical margin principle is one of the central surgical principles for head and neck cancers. Negative surgical margin is the primary purpose of surgery for head and neck cancers. This paper is based on the current clinical application of surgical margins of head and neck cancers, and it is proposed that surgical margins of head and neck cancers may be classified into three types: surface margin, deep margin, and tissue interface margin in consideration of surgical exposure of tumors. The classification of surgical margins can make the clinical application and the research of surgical margins of head and neck cancers more systematic and clear.

Evaluation of modified Overlap method in digestive tract reconstruction after totally laparoscopic total gastrectomy for gastric cancer / 中国综合临床

Objective To evaluate the clinical effect of modified Overlap method in digestive tract reconstruction of totally laparoscopic total gastrectomy(TLTG) for gastric cancer??Methods The data of 86 patients with gastric cancer who underwent TLTG from January 2014 and January 2017 were collected from the First Hospital of Lanzhou University??All the patients underwent D2 lymphadenectomy??Forty?four patients′digestive tracts were reconstructed with traditional Overlap method (control group),and 42 patients′digestive tracts were reconstructed with modified Overlap method ( modified group )??The intraoperative and postoperative conditions, postoperative tumor?free survival, tumor recurrence and metastasis were compared between the two groups??Follow up lasted as of February 2018??Results TLTG was successfully performed in both groups,and no case was converted to laparotomy??The time of esophagojejunostomy ((20??4±2??3) min vs??(46??5±4??4) min, t＝9??493), total operation time (( 253??3 ± 12??8) min vs??( 278??6 ± 14??9) min,t＝5??462) in the modified group were significantly shorter than those in the control group,and there were significant differences between the two groups ( all P＜0??05)??And there were no significant differences between the the modified group and control group in volume of intraoperative blood loss(( 71??5±12??9) ml vs??(73??2± 15??3) ml , t＝0??286), number of lymph node dissected (( 35??5 ± 4??8) vs??( 34??2 ± 5??6) , t＝0??618),first postoperative exhaust time (( 2??6 ± 0??9) d vs??( 2??7 ± 1??1) d, t＝0??348), postoperative hospitalization time((9??9± 1??6) d vs??( 9??8 ± 1??7) d,t＝0??229) and postoperative complications( 7??1%(3／42) vs??9??1%(4／44), χ2 ＝ 0??207) ( all P＞0??05)??The two groups were followed up for 12～25 months??No recurrence or metastasis occurred??Conclusion Compared with traditional Overlap method,the modified Overlap method can simplify the anastomotic procedures, shorten operation time and achieve an effective and reliable anastomosis effect after TLTG??

Effect of preoperative Nutritional Risk Screening-2002 combined with hematologic inflammatory markers on prognosis of thoracic esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective@#To evaluate preoperative nutritional status and inflammatory status by Nutritional Risk Screening-2002 (NRS-2002) and hematologic inflammatory markers in patients with thoracic esophageal squamous cell carcinoma (ESCC), and to explore their effects on long-term survival prognosis.@*Methods@#A total of 113 patients with thoracic ESCC treated by radical resection were grouped for further analysis according to preoperative NRS-2002 score, systemic inflammation score (SIS) and the combination of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio (CNP) score. The progression free survival (PFS) and overall survival (OS) between groups were compared. Multivariate Cox regression analysis was used to determine the independent prognostic factors of patients with thoracic esophageal squamous cell carcinoma, and the interaction analysis of statistically significant factors was carried out.@*Results@#The median PFS was 21 months for all the patients. The 1-year, 3-year and 5-year PFS rates were 69.0%, 25.7% and 23.1%, respectively. Correspondingly, the median OS was 36 months, and the 1-year, 3-year and 5-year OS rates were 95.6%, 46.2% and 29.2%, respectively. Cox univariate analysis showed that T stage, N stage, TNM stage, SIS, CNP score and NRS-2002 score were significantly associated with PFS and OS (all P<0.05), and sex was associated with PFS (P=0.032) in patients with thoracic ESCC. Furthermore, cox multivariate analysis showed that TNM stage (HR=1.570, P=0.039), NRS-2002 score (HR=2.706, P<0.001) and CNP score (HR=1.463, P=0.011) were independent prognosis factors of PFS in patients with thoracic ESCC. In cox model interaction analysis, there was a positive interaction between NRS-2002 score and CNP score (RR=2.789, P<0.001).@*Conclusion@#Preoperative NRS-2002 score combined with CNP score are risk factors for prognosis of patients with thoracic ESCC, which can be used as prognostic indicators.
