Objective:To analyze the correlation between the expressions of human epidermal growth factor receptor 2(HER2)and carbohydrate antigen 153(CA153)and the technical parameter of acoustic palpation tissue imaging quantification(VTIQ)in patients with breast cancer.Methods:A total of 80 female patients with breast cancer admitted to The Third People's Hospital of Hefei from May 2018 to May 2020 were selected,including 14 cases at WHO stage Ⅰ,22 cases at WHO stage Ⅱ,31 cases at WHO stage Ⅲ and 13 cases at WHO stage Ⅳ.Another 53 female patients with benign breast diseases who were treated during the same period were selected as controls.At first,all patients underwent routine ultrasound examination,and then they entered the ultrasound VTIQ imaging mode to obtain the mean value of shear wave velocity(SWV).An immunohistochemistry was used to detect HER2 expressions in breast tissues,and Roche E411 electrochemiluminescence immunoassay analyzer was used to detect serum CA153 levels of them.Pearson method was used to analyze the correlation between serum CA153 levels and SWV mean values in patients with breast cancer.Results:Compared with benign patients,the SWV mean value of VTIQ technical parameter,serum CA153 level and HRR2 positive expression rate in patients with breast cancer were significantly higher,and the difference was statistically significant(F=39.107,78.353,P<0.05),respectively.Compared with patients at stages Ⅰ + Ⅱ of breast cancer,the SWV mean value of VTIQ technical parameter,serum CA153 level and HRR2 positive expression rate of patients at stages Ⅲ and Ⅳ of breast cancer significantly increased(t=2.685,3.556,8.326,10.455,P<0.05),respectively.Compared with patients at stage Ⅲ of breast cancer,the SWV mean value of VTIQ technical parameters,serum CA153 level and HRR2 positive expression rate of patients at Ⅳ stage of breast cancer were significantly higher(t=4.632,8.659,P<0.05),respectively.Compared with the SWV mean value of patients with HER2 negative expression of breast cancer,that of patients with HER2 positive expression of breast cancer was significantly higher(x2=59.751,P<0.05).There was a positive correlation between serum CA153 levels and SWV mean values in patients with breast cancer(r=0.501,P<0.05).Conclusion:The SWV mean value of VTIQ parameters is closely related to the expression levels of biomarkers HER2 and CA153 in patients with breast cancer.

Objective:To investigate the prevalence and potential classification of symptoms after total knee arthroplasty (TKA) in patients with knee osteoarthritis (KOA), and to analyze the differences in demographic characteristics and surgical data, compare the different potential subgroups, in order to provide a basis for clinical symptom management plans.Methods:This study was a multicenter cross-sectional survey. Through convenience sampling, patients with KOA undergoing TKA in the orthopaedic wards of four tertiary hospitals in Urumqi were selected as the study from November 2023 to February 2024. The study subjects were surveyed using a general information questionnaire, the Visual Analogue Scale (VAS) for pain, the Hospital Anxiety and Depression Scale (HADS), and the Pitts Burgh Sleep Quality Index (PSQI), and the degree of postoperative joint swelling and size of ecchymosis were measured. Latent class analysis was performed using Mplus 8.3 software, and Logistic regression analysis was conducted using SPSS 26.0 software to explore the influencing factors of the latent classes.Results:Totally 337 effective questionnaires were collected, and the recovery rate was 94.7% (337/356), and the age distribution ranged from 47 to 85 (65.19 ± 6.99) years old, with 90 (26.7%) males and 247 (73.3%) females. There were 92.3% (311/337) of TKA patients with postoperative symptom cluster. The symptom cluster of patients with TKA were identified as 3 classes. They were named as "high level pain-psychological disorder group"(12.5%, 39/311), "high bruises-moderate psychological disorders group"(25.4%, 79/311) and "low symptom burden group" (62.1%, 193/311). The results of the unordered multi-class logistic regression analysis showed that age 45-59 years ( OR = 2.367), body mass index 24.0-27.9 kg/m 2 ( OR = 0.207), living with children/parents ( OR = 6.473), and this being the second joint surgery ( OR = 0.040) were the factors influencing the "high level pain-psychological disorders group" (all P<0.05). The factors influencing the "high bruises-moderate psychological disorders group" were living with children/parents ( OR = 4.023), comorbid chronic diseases ( OR = 1.979, 3.842), and intraoperative blood loss ≤100 ml ( OR = 2.342) (all P<0.05). Conclusions:The postoperative symptom cluster of TKA patients have a relatively high incidence, and there is heterogeneity within the symptom cluster, so nurses need to identify at-risk patients early according to the characteristics of different categories and give interventions.

Objective:To study the clinical effect of sacrospinous ligament fixation (SSLF) and traditional vaginal hysterectomy on pelvic organ prolapse (POP) .Methods:A retrospective analysis was performed on 68 patients with POP of degree II-IV admittedl from Jan. 2017 to Dec. 2019. Among them, 33 patients were treated with SSLF (observation group) and 35 patients were treated with vaginal total hysterectomy (control group). Intraoperative blood loss, operative time, postoperative indwelling catheter and average length of hospital stay were compared between the two groups. The patients were followed up for 6 months, and the scores of pelvic floor dysfunction questionnaire-20 (PFDI-20) and sexual quality questionnaire -12 (PISQ-12) were used to evaluate the subjective satisfaction degree of postoperative recovery.Results:In the observation group, the intraoperative blood loss (173.94±52.14) ml, postoperative indurating catheter time (2.72±0.45) d and average length of hospital stay (7.09±0.63) d were observed. There were statistically significant differences in intraoperative blood loss (228.86±53.40) ml, postoperative induration time (4.54±0.61) d and mean hospital stay (9.22±0.81) d in the control group ( P<0.05). There was no significant difference in the operation time between the observation group (99.57±9.50) min and the control group (101.06±8.64) min, ( P>0.05). The improvement of PFDI-20 and PISQ-12 in both groups was significant before and after treatment. The PISQ-12 score of the observation group was higher than that of the control group 6 months after surgery, and the difference was statistically significant ( P <0. 05). There was no significant difference in PFDI-20 score between the two groups ( P>0.05). There was statistical significance in the positions of pop-Q indicators in the two surgical methods ( P < 0.05) . Conclusions:SSLF with uterus preservation and total vaginal hysterectomy are both effective in treatment of moderate and severe POP. However, SSLF with uterus preservation has less intraoperative blood loss, and the postoperative recovery is significantly better than that with total vaginal hysterectomy. In addition, it satisfies patients’ desire to preserve uterus, improves the postoperative sexual life quality, which is worthy of promotion.

ObjectiveTo explore the effect of mindfulness-based childbirth on pregnant women's anxiety and depression， and to provide references for related psychological intervention. MethodsA total of 80 pregnant women who attended the obstetrics department of the Third People's Hospital of Mianyang from October 2018 to March 2019 and met the diagnostic criteria of mild to moderate anxiety and depression in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were selected， and they were divided into two groups by random number table method， each with 40 cases. Both groups received regular mental health education. On this basis， experimental group received mindfulness-based childbirth training for 8 times， once a week. Meantime， all pregnant women were assessed using Patient Health Questionnaire-9 item （PHQ-9） and Generalized Anxiety Disorder Scale （GAD-7） at the baseline and after intervention. ResultsAt the baseline and after intervention， the scores of PHQ-9 ［（6.95±1.40） vs. （2.10±1.34）， P<0.05］ and GAD-7 ［（7.23±1.29） vs. （2.08±1.51）， P<0.05］ in the experimental group had statistical significance， and the scores of PHQ-9 ［（7.00±1.43） vs. （3.65±1.35）， P<0.05］ and GAD-7 ［（7.18±1.57） vs. （3.38±1.66）， P<0.05］ in the control group had statistical significance. Moreover， the post-intervention scores of PHQ-9 and GAD-7 were significantly lower in experimental group than in control group （t=5.161， 3.666， P<0.01）. ConclusionCompared with mental health education alone， its combination with mindfulness-based childbirth achieves better effect in alleviating the anxiety and depression status of pregnant women.

The laparoscopic vision platform developed from the prototype of candlelight reflector device to HD, 3D and 4K ultra HD, which revolutionized surgery from open surgery to minimally invasive surgery. With the continuous application in gastric cancer surgery, the importance of laparoscopy in radical gastrectomy is gradually recognized. Radical gastrectomy mainly includes lymph node dissection and digestive tract reconstruction. The reconstruction of digestive tract after radical gastrectomy for distal gastric cancer has been a hot topic of discussion and research, which is directly related to the incidence of postoperative complications, nutritional status and quality of life. This paper mainly discusses the Roux-en-Y digestive tract reconstruction of radical gastrectomy for distal gastric cancer with 4K laparoscopic.

According to the current evidence-based medicine researches, the eastern and western countries have reached a consensus that D2 operation is a standardized procedure for advanced gastric cancer.However, the postoperative five-year survival rate is still not satisfactory. Professor Gong Jianping of Tongji Hospital, Tongji Medical Gollege of Huazhong University of Science and Technology proposed a theory of membrane anatomy (the third element of surgical anatomy) and the concept of cancer leakage—an epoch-making concept in surgical anatomy. The Department of Gastrointestinal Surgery, The Affiliated Hospital of Guizhou Medical University was honored to be selected as one of the first domestic replication units of 3D laparoscopic radical gastrectomy under membrane anatomy. Professor Gong Jianping has visited our hospital several times for surgical demonstration, explanation of membrane anatomy theory and replication training. Through the understanding of membrane anatomy theory, we found that 3D laparoscopic radical gastrectomy guided by membrane anatomy can achieve good results, e.g less bleeding, complete resection, complete lymph node dissection and avoidance of side damage, meanwhile the operation is simple and safe. At the same time, it can avoid the shedding of cancer cells, so as to reduce the iatrogenic leakage of cancer and improve the efficacy of radical gastrectomy. In addition, the standardized procedure of laparoscopic radical gastrectomy makes it scientific, reproducible and easy to be popularized.

Objective To investigate the clinical efficacy of microsurgical repair of soft tissue necrosis after beak-type calcaneal fracture.Methods From January,2012 to March,2017,surgically flaps were used to repair wounds in 8 patients with soft tissue necrosis after calcaneal beak fracture.Five patients underwent sural neurovascular flap in the first stage of repair,2 patients were treated with peroneal perforator propeller flap,and 1 patient was treated with posterior tibial artery perforator propeller flap.The donor sites of 3 flaps were directly closed,and donor areas of the remaining 5 were covered with medium-thickness skin grafts without being sutured directly.The size of flap was 5.0 cm× 3.0 cm-7.0 cm × 5.0 cm.Through postoperative outpatient and WeChat follow-up.The patient's flap survival,infection,flap shape,sensation and ankle function were evaluated.Results All flaps and skin grafts survived post-operatively.All patients were followed-up for 6-12 (mean,8.4) months.All patients had good flap survival and no complications such as soft tissue and calcaneal infection.The flaps were good in texture,shape and function of ankle.At the last follow-up,according to the British Medical Research Institute (BMRI),the sensory function was divided into 6 levels.The flap sensory function recovered to S2 in 3 cases,and the remaining 5 cases was S1.According to the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-hindfoot Scale (AHS),the results were excellent in 5 cases,and good in 3 cases.All patients had good clinical results and satisfaction at the last followedup.Conclusion The treatment of soft tissue necrosis after calcaneus beak fractures can be completed in one stage by using flaps,which avoided the occurrence of calcaneal osteomyelitis.It is easy to perform early rehabilitation exercise and the ankle function is well restored.

Objective: To investigate the clinical value of endoscopic ultrasonography (EUS) and Multi-slice Spiral CT (MSCT) in the preoperativestaging of tumor(T) and lymph node (N) metastasis in patients with SiewertⅡand Ⅲ typeadenocarcinoma of esophagogastric junction(AEG). Methods: Clinical data of 145 Siewert Ⅱ and Ⅲ type AEG patientswithout preoperative chemoradiotherapy were retrospectively reviewed. Theyall received preoperative EUS and MSCT examination and underwent surgical resection, and the results of EUS and MSCT were compared with their postoperative pathologic staging. Results: The sensitivity, specificity, and accuracy of EUS for T stage in Siewert Ⅱ and Ⅲ type AEG were higher than those of MSCT. The total accuracy of EUS and MSCT were 90.3% and 63.5%, respectively, and the difference was statistically significant (χ²=29.52, P<0.01). The sensitivity of EUS for T1, T2 and T3 were 89.5%, 91.1% and 85.2%, respectively, which were significantly higher than 42.1%, 66.7% and 29.6% of MSCT (χ²=9.47, P<0.01 for T1; χ²=8.07, P<0.01 for T2; χ²=17.40, P<0.01 for T3). In addition, the total accuracy of EUS and MSCT for lymph node metastasis status of Siewert Ⅱ and Ⅲ type AEG were 75.9% and 64.8%, respectively, showing a statistically significant difference(χ²=4.23, P=0.04). The sensitivity of EUS for N1 and N2 were 82.1% and 79.2%, respectively, which were significantly higher than 53.6% and 60.4% of MSCT (χ²=5.24, P=0.02; χ²=4.48, P=0.03). There was no statistical significance for sensitivity of EUS and MSCT in N0 and N3 (P>0.05). Conclusion EUS diagnosis of T and N staging in Siewert Ⅱ/Ⅲ type AEG showed significantly greater performance than MSCT.
