Objective:To investigate the safety and effectiveness of robot-assisted total knee arthroplasty (TKA).Methods:From August 2021 to March 2022, the data of 69 patients who received robot-assisted TKA for inflammatory disease of knee in 6 hospitals were collected, including 24 males and 45 females, aged 52±6 years (range, 46-72 years), including 53 cases of knee osteoarthritis,10 cases of rheumatoid arthritis, and 6 cases of traumatic arthritis. Imaging data examination of patients was completed according to the multicenter specification. Preoperatively, the patient's CT data were extracted before surgery and a personalized prosthesis positioning plan was designed by the robotic system to determine the prosthesis size, lower limb force lines, and femoral and tibial osteotomy volumes; intraoperatively, the osteotomy template was robotically controlled to complete the osteotomy according to the prosthesis positioning plan, and the intraoperative osteotomy volumes were measured to verify the accuracy of the robot-assisted TKA osteotomy with the preoperative planning. Postoperatively, the lateral angle of the distal femur, the medial angle of the proximal tibia and the hip-knee-ankle angle were measured in the coronal plane according to radiographs; the postoperative outcome was evaluated 3 months after operation, using the American Knee Society score (KSS), including the KSS knee score and functional score.Results:The operative time was 97.3±2.3 min (range, 80-110 min) and the amount of bleeding was 320.0±6.2 ml (range, 300-350 ml) in 69 patients. Three months after operation, the mean range of motion of knee joint was increased from 82.2°±1.1° before surgery to 119.7°±0.8° after surgery ( t=27.65, P<0.001), and the line of force of lower limb was improved from 160.9°±0.5° before surgery to 178.0°±0.2° after surgery ( t=32.03, P<0.001). KSS-knee score increased from 54.8±0.7 points before operation to 85.0±0.5 points after operation, and KSS-functional score increased from 56.5±0.7 points before operation to 85.9±0.4 points after operation, the difference was statistically significant ( t=35.45, 36.58, P<0.001). The proportion of patients with intraoperative femoral and tibial osteotomies within 2 mm osteotomy error compared with preoperative planning was 97% for the lateral tibial plateau, 100% for the medial tibial plateau, 100% for the lateral distal femur, 99% for the medial distal femur, 93% for the lateral posterior femoral condyle, and 100% for the medial posterior femoral condyle; The proportion of patients with postoperative anteroposterior X-ray measurement angle error within 3° was: 100.0% for the distal lateral femoral angle, 100.0% for the proximal medial tibial angle, and 100% for the hip-knee-ankle angle. No complications occurred in all patients except for one case in which fat liquefaction occurred in the postoperative wound. Conclusion:Robot-assisted TKA is a safe and effective surgical method for the treatment of inflammatory disease of knee with accurate prosthesis installation and good postoperative recovery of lower limb alignment.

Objective:To observe the clinical outcomes of continued pregnancy in pregnant women with cesarean scar pregnancy (CSP).Methods:A retrospective analysis was performed on the pregnancy outcomes of 55 pregnant women who were diagnosed with CSP at the Second Affiliated Hospital of Army Medical University during the first trimester of pregnancy from August 1st, 2018 to October 31st, 2021 and strongly requested to continue the pregnancy.Results:Of the 55 pregnant women, 15 terminated the pregnancy in the first trimester, 1 underwent hysterotomy at 23 weeks of gestation due to cervical dilation, and 39 (71%, 39/55) continued pregnancy to the third trimester achieving live births via cesarean section. The gestational age of the 39 pregnant women delivered by cesarean section was 35 +6 weeks (range: 28 +5-39 +2 weeks), of whom 7 cases at 28 +5-33 +6 weeks, 20 cases at 34-36 +6 weeks, and 12 cases at 37-39 +2 weeks. The results of pathological examination were normal placenta in 3 cases (8%, 3/39), placenta creta in 4 cases (10%, 4/39), placenta increta in 9 cases (23%, 9/39) and placenta percreta in 23 cases (59%, 23/39). Among the 36 pregnant women who were pathologically confirmed as placenta accreta spectrum disorders (PAS) after surgery, the last prenatal ultrasonography showed placenta previa in 27 cases (75%, 27/36) and not observed placenta previa in 9 cases. The median intraoperative blood loss, autologous blood transfusion, and allogeneic suspended red blood cell infusion of 39 pregnant women during cesarean section were 1 000 ml (300-3 500 ml), 300 ml (0-2 000 ml) and 400 ml (0-2 400 ml), respectively. The uterine preservation rate was 100% (39/39), and only 1 case received cystostomy due to intracystic hemorrhage. The birth weight of the newborn was 2 580 g (1 350-3 800 g), and 1 case of mild asphyxia. Conclusions:Pregnant women with CSP who continue pregnancy under close monitoring after adequate ultrasound evaluation and doctor-patient communication could achieve better maternal and infant outcomes, but pregnant women with CSP are highly likely to continue pregnancy and develop into PAS. Effective hemostasis means and multidisciplinary team cooperation are needed in perinatal period for ensuring maternal and fetal safety.

Objective To explore the effect of medical and nursing integration notification on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemotherapy. Meth-ods From February to March 2017,34 patients for the first time needing chemotherapy were included as control group,using normal disclosure.From June to July 2017,35 cases for the first time needing chemother-apy were included as the experimental group. The experimental group was informed of the medical and nurs-ing integration notification. The truth knowing rate,anxiety,depression and quality of life were compared be-fore and after three cycles of chemotherapy. Results After three cycles of chemotherapy,the truth knowing rate of patients in the experimental group (completely 57.14%,partly 34.29% and none 8.57%) was signifi-cantly different with the control group (completely 29.42%,partly 35.29% and none 35.29%,P＜0.01). The scores of anxiety and depression in the experimental group(39.43±4.60,41.86±5.23) were significantly low-er than those before chemotherapy(42.37±4.76,45.69±5.49,P＜0.01). The scores of anxiety and depression in the control group (45.74±5.20,49.74±5.42) were significantly higher than those before chemotherapy (42.77±5.62,45.56±6.27,P＜0.01).After three cycles of chemotherapy,the scores of anxiety and depression in the experimental group were lower than the control group (P＜0.01). After three cycles of chemotherapy, the total health status,body function,role function,emotional function,cognitive function,social function,fa-tigue,nausea and vomiting,and loss of appetite were statistically significant between the experimental group and control group (P＜0.05). Conclusion The medical and nursing integration notification has a positive effect on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemo-therapy.

Objective To investigate the Demodex infection status and influencing factors in medical students in Wuhu City. Methods The mite specimens were collected by the cellophane tape method,and the influencing factors were investigated through the questionnaires. Results A total of 316 medical students were surveyed,117 students were infected with Demodex mite,and the total infection rate was 37.03%. There was no significant difference between the male and female in the infection rate( χ2 = 0.00,P > 0.05). Of the 117 infected cases,the infection rate of simple Demodex folliculorum was 51.28%,the infec-tion rate of simple Demodex brevis was 24.79%,and the rate of mixed infections was 23.93%. The rate of the mild infection (83.76%)was significantly higher than that of the moderate infection(12.82 %)and that of the severe infection(3.42%). The infection rate in the forehead was the highest(29.41%). Among the students with the oily skin,the infection rate of Demodex mite was related to sex. The infection rate of simple Demodex brevis in the male(3.70%)was lower than that in the female (16.42%)( χ2 = 6.92,P < 0.05),while the rate of the mixed infections in the male(17.28%)was higher than that in the fe-male(4.48%)( χ2 = 5.91,P < 0.05). The infection rate of facial skin with symptoms(51.80%)was higher than that of normal facial skin(33.05%)( χ2 = 9.14,P < 0.01). There was no significant difference between the infection rate of Demodex mite and the living habits and other factors. Conclusions There is some infection of Demodex in the medical students. The infection rate of facial skin with symptoms is higher than that of the normal facial skin. So we should strengthen the prevention and treat-ment of Demodex infection in medical students.

Truth disclosure of cancer patients is becoming more and more recognized in the world.Truth disclosure is usually regarded as the doctor's responsibility.However,the nurse has become an active participant in the truth disclosure of cancer patients both intentionally and inadvertently.This article systematically reviewed the role of nurses at home and abroad in informing patients with cancer the truth so as to provide guidance for the clinical practice.In April 2017,we retrieved articles in Pubmed,Chinese CNKI,Wanfang database,VIP database,and retrieval time is not restricted.A total of 92 literatures were retrieved and 8 articles were retrieved by manual searching.Finally,23 articles were included.Through systematic review of the literature,nurses are found to play an important role in informing cancer patients the truth.Compared with physicians,nurses have a more positive attitude for truth disclosure.Nurses have the most contact with patients and family members,if the nurses have plans to communicate with the families on telling the truth to cancer patients,there will be a positive impact on the truth disclosure attitude of family members.It is necessary to explore the strategy of truth disclosure for cancer patients with integrated medical staff in the future.

OBJECTIVETo study the effects of RhoA down-regulation by RNA interference on the invasion of tongue carcinoma Tca8113 and SCC-4.

METHODSDetermination of the human RhoA sequence as well as the design and constructionof a short specific small interfering RNAs (siRNA) were performed. The siRNA of RhoA gene was transfected into humantongue squamous cell carcinoma Tca8113 and SCC-4 cells line by Lipofectamine 2000. Quantitative real-time polymerasechain reaction was used to examine the mRNA expressionlevels of RhoA. Protein expressions of mRNA, galectin-3,and matrix metalloproteinase (MMP)-9 were evaluated byWestern blot. Transwell invasion assay was performed toassess the invasion ability of tongue carcinoma.

RESULTSRhoA expressions in Tca8113 and SCC-4 cells were reducedsignificantly after transfection of RhoA-siRNA. Protein levels f galectin-3 and MVP-9 were also down-regulated significantly. Invasion ability was inhibited as well.

CONCLUSIONRhoA-siRNA can effectively inhibit RhoA expression in Tca8113 and SCC-4 cells. The invasion ability of tongue carcinoma cells decreased with down-regulation of the protein expressions of galectin-3 and MMP-9, indicating that RhoA-siRNA can inhibit invasion of tongue carcinoma. Results show that RhoA may play an important role in the processes of invasion and metastasis of tongue carcinoma.
