Flexible ureteral lithotripsy (FURL) under general anesthesia (GA) is the dominant method in the treatment of renal and upper ureteral calculi，but some patients cannot tolerate GA.In recent years，there has been a growing interest in the use of local anesthesia (LA) as a safe and effective alternative.And it is also an option for patients who have calculi ≤20 mm with high fragility，lower CT value and better compatibility.Before surgery，it is important to conduct relevant examinations，evaluate the status of patients，prevent infections，and indwell ureteral stents.During surgery，lithotomy position，scissors position，prone leg position and other positions should be selected according to the specific conditions of patients.LA drugs should be used to control physiological pain and relieve psychological anxiety.Patients' breathing state should be carefully monitored，and appropriate ureteroscope and lens sheath should be selected for the success and safety of the operation.In this paper，the perioperative management of FURL under LA is briefly summarized，so as to provide reference for clinical practice.

Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency， it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat， spleen and stomach damp-heat， and spleen deficiency is divided into deficiency of spleen yin， deficiency of spleen qi ， and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories，i.e. stomach-heat and spleen yin-deficiency， stomach-heat and spleen qi-deficiency， and stomach-heat and spleen yang-deficiency， and the main treatment methods are clearing and draining heat， nourishing yin and moistening intestine， clearing dampness and heat， strengthening spleen and qi， clearing dampness and heat， strengthening spleen and warming yang， respectively， with prescriptions as Maziren Pills （麻子仁丸）， Qinlian Pingwei Powder （芩连平胃散）， and Jiawei Lianli Decoction （加味连理汤） accordingly.

Objective To investigate the prevalence and molecular features of Cryptosporidium in captive-bred Mustela putorius furo in Jiangsu Province.. Methods A total of 290 fresh stool samples were collected from a ferret farm in Jiangsu Province on May 2017, and the small subunit rRNA (SSU rRNA) gene of Cryptosporidium was amplified in stool samples using nested PCR assay. The actin, cowp and gp60 genes were amplified in positive samples and sequenced to characterize Cryptosporidium species/genotypes. Results A total of 18 stool samples were tested positive for Cryptosporidium SSU rRNA gene, with a detection rate of 6.2%. Sequence and phylogenetic analyses of SSU rRNA, actin and cowp genes characterized Cryptosporidium isolated from captive-bred ferrets as Cryptosporidium sp. ferret genotype. In addition, gp60 gene was amplified in 10 out of 18 stool samples tested positive for Cryptosporidium. Conclusions Cryptosporidium is widely prevalent in captive-bred ferrets in Jiangsu Province, and Cryptosporidium sp. ferret genotype is the only Cryptosporidium genotype in ferrets.

Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.

【Objective】 To understand the memory phenotype and function of SARS-CoV-2 reactive CD4+ T cells in healthy individuals. 【Methods】 In this study, SARS-CoV-2-derived peptides were used to stimulate PBMC from participants.SARS-CoV-2 reactive memory T cells were detected by intracellular staining and flow cytometry, and memory phenotype analysis was performed.CBA was used to detect cytokine secretion after SARS-CoV-2-derived peptides stimulation to evaluate the function of SARS-CoV-2 reactive memory T cells. 【Results】 We found that SARS-CoV-2 reactive CD4+ memory T cells could be detected in 40% (6/15) healthy donors.Phenotypic analysis of memory showed that these T cells were mainly composed of central memory T cells(82.2%), and other memory cells accounted for 17.8%.Compared with negative control, IL-10 was significantly decreased after stimulation of SARS-CoV-2-derived peptides (P<0.05), while the secretion of IFNγ, TNFα, IL-2 and IL-4 showed no significant difference. 【Conclusions】 SARS-CoV-2 reactive CD4+ memory T cells are present in healthy individuals from China.

Objective:To explore the feasibility and safety of long-distance urological nephrotomy with the support of 5G communication technology by using the domestic robot.Methods:Clinical data of the patients with remote robot-assisted laparoscopic nephrectomy, which were completed from March to April 2021 by the Affiliated Hospital of Qingdao University (as the host hospital where the main operating system located) were retrospectively analyzed. There were 3 patients, including 2 males and 1 female.The average age was 61 (49-73) years, and the average body mass index was 23.73 (20.00-27.76) kg/m 2. One patient had a ASA classification of grade 2, and the other 2 patients had grade 3. All patients met the surgical criteria for non-functional nephrectomy. The chief surgeon who performing the telesurgery was located at the Affiliated Hospital of Qingdao University. The surgeon remotely controlled the bedside operating system (slave system) in 3 local hospitals located in other cities in Shandong Province (network communication distances of 82.5, 141 and 229 km, respectively) by manipulating the master system located in Qingdao. Images and operating instructions during surgery were transmitted using 5G wireless communication technology. Intraoperative network conditions, robot operation, and patient perioperative data were summarized. Results:All 3 tele-nephrectomies were successfully completed. The average network signal latency time was 27.3 (23-30) ms, with no packet loss, and the average total latency time was 177.3(173-180) ms. The mean resection time was 79.3 (52-111) min, and the average intraoperative blood loss was 31.1 (15.6-41.9) ml. There were no network related adverse events occurred during the operation, and the robot-related adverse events occured 3 times, all three of which were characterized by inconsistent master and slave movements of the manipulator arm and the bedside robotic arm. None of these adverse events affected the successful performance of the telesurgery. The mean postoperative exhaust time was 60.5 (38.5-78.0) h. The mean postoperative VAS score at 24 hours was 3.7 (3-4). The Clavien-Dindo classification were all grade I. No significant abnormality was found on the 30th day after surgery, and the patients recovered well at the follow-up until 6 months postoperatively.Conclusions:It is safe and feasible to perform remote robot-assisted laparoscopic nephrectomy based on 5G communication technology with no serious adverse events or surgical complications.However, the conclusion needs to be further verified by large sample and multi-center prospective study.

Objective:To investigate the status of monotherapy for newly diagnosed tic disorders and its comorbidity in children, so as to provide a reference for clinical medication.Methods:A questionnaire survey was conducted to collect the application experience of monotherapy for newly diagnosed tic disorders and comorbidities in 110 pediatric neurologists and psychiatrists from Chinese Tic Disorders Study Consortium from February to August in 2019. Doctors were asked to rate treatment options based on a rank 5-point scale with "1" least appropriate and "5" most appropriate. The drug evaluation index was based on the comparison of the median score of a single drug with the overall scores of all drugs in this disease ( M( Q1, Q3)), single drug M≥ overall Q3 was recommended as preferred drugs; overall Q1≤ single drug M< overall Q3 was considered as secondary drugs; single drug M< overall Q1 was considered as unsuitable drugs. Results:Among 110 electronic questionnaires, 94 (86%) were availably responded, responding doctors included 37 (39%) males and 57 (61%) females, the age of responding doctors was (48±10) years, and their working year was (17±10) years. In the investigation of the first and second monotherapy for newly diagnosed tic disorders in children without comorbidities, there were no preferred drugs for mild transient tic disorders. The scores of clonidine, aripiprazole and tiapride were 4 (3, 4), 4 (3, 4), 4 (4, 5) scores respectively, and were greater than overall scores (3 (2, 4) scores), so they could be recommended as the preferred drugs for moderate chronic tic disorders, the recommendation for initial mild Tourette syndrome (TS) treatment was the same as preferred drugs for moderate chronic tic disorders. Similarly, clonidine, aripiprazole, tiapride and haloperidol could be recommended as the preferred drugs for other kinds of tic disorders. As for the second monotherapy, the preferred drugs for moderate transient tic disorders, mild chronic tic disorders and severe TS were all aripiprazole, tiapride, haloperidol, sulpiride, clonidine and topiramate. While clonidine, aripiprazole, tiapride could be considered as preferred drugs for severe transient tic disorders, moderate to severe chronic tic disorders and mild to moderate tic disorders. In the investigation of monotherapy for newly diagnosed tic disorders in children with comorbidities, for moderate chronic tic disorders and TS comorbid with obsessive-compulsive disorder, aripiprazole (4 (3, 5) scores) and sertraline (4 (3, 4) scores) were preferred drugs,the median scores of which were all greater than overall scores (3 (3, 4) scores), they were also the preferred treatment for severe transient tic disorders and mild chronic tic disorders. For mild and moderate transient tic disorders, severe chronic tic disorders and TS comorbid with obsessive-compulsive disorder, aripiprazole, fluvoxamine, fluoxetine, haloperidol and sertraline were preferred drugs. When comorbid with attention deficit hyperactivity disorder (ADHD), severe transient tic disorders, moderate chronic tic disorders and TS, tomoxetine and clonidine were recommended as preferred drugs (both 4 (4, 5) scores), and tomoxetine and clonidine were also the preferred treatment for severe TS. For severe chronic tic disorders comorbid with ADHD, clonidine (5(4, 5) scores) was preferred drug, greater than overall scores (4 (3, 5) scores), while for mild and moderate transient tic disorders clonidine, tomoxetine, guanidine and methylphenidate were recommended as preferred drugs. For mild chronic tic disorders and TS comorbid with ADHD tomoxetine was preferred drug. When comorbid with sleep disorders, there were no preferred drugs for mild transient tic disorders; estazolam (3 (2, 3) scores) was the preferred drug for mild chronic tic disorders and TS comorbid with sleep disorders. For othe kind of tic disorders comorbid with sleep disorders, estazolam, melatonin and clonazepam were preferred drugs. When comorbid with anxiety and depressive disorders, for all kinds of tic disorders sertraline was recommended as preferred drugs, the median scores of sertraline were all (4 (3, 5) scores) in severe transient tic disorders, moderate to severe chronic tic disorders and moderate TS, and greater than overall scores (3 (3, 4) scores). While severe chronic tic disorders comorbid with anxiety and depressive disorders, fluvoxamine could also be chosen as preferred drugs.Conclusions:Drug therapy is not recommended for mild transient tic disorders, while tiapride, aripiprazole, clonidine, and haloperidol are mainly preferred drugs for the other kinds of tic disorders. Corresponding drugs should be selected when tic disorders are combined with obsessive-compulsive disorder, ADHD, sleep disorders, anxiety, depression, etc.

Objective To investigate the long-term efficacy of pure transanal total mesorectal excision (PtaTME) for middle-low rectal cancer.Methods The retrospective descriptive study was conducted.The clinicopathological data of 18 patients with middle-low rectal cancer who were admitted to the Sixth Affiliated Hospital of Sun Yat-sen University from July 2014 to August 2016 were collected.There were 7 males and 11 females,aged (58±13) years,with a range from 40 to 84 years.The body mass index was (22±3) kg/m2.All the 18 patients underwent PtaTME.Observation indicators:(1) surgical and postoperative conditions;(2) postoperative pathological examination;(3) follow-up and survival.Follow-up using inpatient reexamination,outpatient examination,and telephone interview were performed to detect anastomotic complications,anal function,urinary retention,sexual dysfunction,survival and tumor recurrence and metastasis once every 3 months within postoperative 6 months,once every 6 months from 6 months to 3 years,and once a year after 3 years up to June 2019.The measurement data with normal distribution were represented as Mean±SD,and the measurement data with skewed distribution were represented as M (range).Count data were expressed as percentages.Survival rates were calculated by the Kaplan-Meier method.Results (1) Surgical and postoperative conditions:18 patients successfully underwent PtaTME,without conversion to open surgery.The operation time,volume of intraoperative blood loss,distance between anastomosis and anal verge,time to first flatus,time to urinary catheter removal,and duration of postoperative hospital stay were (202±68) minutes,50 mL (range,20-400 mL),(4.5± 2.0)cm,2 days (range,2-7 days),3 days (range,2-5 days),and 7 days (range,5-10 days) in the 18 patients,respectively.There was no perioperative complication.Among 18 patients,4 underwent preventive ileostomy.(2) Postoperative pathological examinations:the length of surgical specimens,the number of lymph node dissection,distance from tumor to the distal margin were (11.0±3.0)cm,12±6,and 1.0 cm (range,0.8-3.7 cm),respectively.The 18 patients had complete mesorectal membrane excision,with negative proximal margin,distal margin,and circumferential margin.Tumor pathological staging:there were 2 cases in Tis stage,4 in T1 stage,7 in T2 stage,and 5 in T3 stage;16 in N0 stage,1 in N1 stage,and 1 in N2 stage.Tumor histological classification:2 patients had carcinoma in situ,9 had moderately differentiated adenocarcinoma,and 7 had high-differentiated adenocarcinoma.(3) Follow-up and survival:18 patients were followed up for 34.0-59.0 months,with a median follow-up time of 57.5 months.During the follow-up,4 patients developed grade B anastomotic leakage and were cured after conservative treatment.One patient developed anastomotic recurrence at 2 years after surgery,and no recurrence was found after surgical resection of the recurrent lesion.Four patients with prophylactic ileostomy had the stoma closured,and the anus function was satisfactory after surgery.There was no urinary retention or sexual dysfunction in the 18 patients.Of the 18 patients,17 had tumor free survival after surgery.The 3-year disease-free survival rate was 94.4％,and the 3-year overall survival rate was 100.0％ in 18 patients.Conclusion PtaTME can achieve high quality of specimen,which is safe and feasible for the treatment of rectal cancer.
