Objective To determine the half-effective target effect-site concentration (Ce) (EC50) of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol in patients undergoing transureteroscopic holmium laser lithotripsy. Methods Fifty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr, BMI ＜ 30 kg/m2 , undergoing transureteroscopic holmium laser lithotripsy were randomly divided into 5 groups according to the different C es of sufentanil ( n = 10 each): group S1 (Ce 0.21 ng/ml), group S2(Ce 0.14 ng/ml), group S3(Ce 0.09 ng/ml), group S4(Ce 0.06 ng/ml), group S5(Ce 0.04 ng/ml). TCI of propofol with target plasma concentration set at 2.5-3.0 μg/ml was given. Sufentanil with the corresponding Ce was infused in each group. The ureteroscopes were inserted as soon as the patients lost consciousness and the effect-site concentration of sunfentanil was achieved. The response was defined as positive when body movement occurred within 1 min after insertion of ureteroscopes. The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol and 95% confidence interval (CI) were calculated. Results The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol was 0.084 ng/ml and 95% CI was 0.066-0.107 ng/ml. Conclusion The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes was 0.084 ng/ml when combined with propofol.

OBJECTIVE To illuminate the adenoid bacteria distribution in children with adenoid hypertrophy. METHODS PubMed, Embash, Medline, CNKI, VIP Information and Wanfang data were searched for studies on the adenoid bacteria distribution and adenoid hypertrophy. Random effects meta-analysis was used to pool data. RESULTS Nine studies were included in this meta analysis. The pooled detection rates of haemophilus influenza, staphylococcus aureus and streptococcus pneumonia were 0.21 (95%CI, 0.09-0.32), 0.14 (95%CI, 0.09-0.20) and 0.15 (95%CI , 0.08-0.22) respectively. CONCLUSION Haemophilus influenzae, staphylococcus aureus, and streptococcus pneumoniae are three main kinds of pathogenic bacteria of adenoid hypertrophy in children.

Objective:To evaluate the optimized effect of infiltration between the popliteal artery and the capsule of the knee (IPACK)-adductor canal block (ACB) combined with general anesthesia when used for the total knee arthroplasty.Methods:Sixty patients of both sexes, aged 18-64 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective unilateral total knee arthroplasty, were divided into 2 groups ( n=30 each) using a random number table method: IPACK-ACB combined with general anesthesia group (group IA) and conventional anesthesia femoral nerve block-popliteal superior sciatic nerve block combined with general anesthesia group (group C). Before induction of general anaesthesia, 0.375% ropivacaine 15 ml was injected for IPACK and 0.375% ropivacaine 25 ml for ACB under the ultrasound guidance in group IA, femoral nerve block and popliteal superior sciatic nerve block was performed under the guidance of ultrasound combined with a nerve stimulator and 0.375% ropivacaine 20 ml was injected in group C. After confirming the efficacy of nerve block, total intravenous anesthesia was carried out to maintain bispectral index values at 40-60.Patient-controlled intravenous analgesia was performed with sufentanil after operation, and the visual analog scale score was maintained ≤ 3.The quadriceps muscle strength score was recorded when discharge from postanesthesia care unit and at 24, 48 and 72 h after surgery.The first postoperative off-bed time and development of foot drop in awake patients after surgery, requirement for rescue analgesia and adverse reactions were recorded.The postoperative length of hospital stay and score for patients′ satisfaction with postoperative recovery were also recorded. Results:Compared with group C, the postoperative quadriceps muscle strength scores and score for patients′ satisfaction with postoperative recovery were significantly increased, the incidence of postoperative foot drop was decreased, and the length of hospital stay and first postoperative off-bed time were shortened in group IA ( P<0.05). Conclusion:IPACK-ACB combined with general anesthesia may be an optimized strategy which is helpful for outcomes after total knee arthroplasty.

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.

The ectopic salivary gland refers to the presence of salivary gland tissue in an area other than the site where salivary glands normally exist. They often occur near the line connecting the external ear canal and the medial border of the clavicle. It is extremely rare to occur in the urogenital system. This paper retrospectively analyzed the clinicopathological data of a patient with ectopic salivary glands accidentally discovered due to testicular torsion. Patients are generally asymptomatic. If there is no fistula leading to the skin or mucosal surface, it is difficult to find clinically. The diagnosis depends on postoperative pathological examination. For ectopic salivary glands, surgery is required regardless of the location.

OBJECTIVES: To investigate the genetic causes of hearing loss with enlarged vestibular aqueduct (EVA) in two children from unrelated two Chinese families. METHODS: Sanger sequencing of all coding exons in SLC26A4 (encoding Pendrin protein) was performed on the two patients, their sibling and parents respectively. To predict and visualize the potential functional outcome of the novel variant, model building, structure analysis, and in silico analysis were further conducted. RESULTS: The results showed that the proband from family I harbored a compound heterozygote of SLC26A4 c.1174A>T (p.N392Y) mutation and c.1181delTCT (p.F394del) variant in exon 10, potentially altering Pendrin protein structure. In family II, the proband was identified in compound heterozygosity with a known mutation of c.919-2A>G in the splice site of intron 7 and a novel mutation of c.1023insC in exon 9, which results in a frameshift and translational termination, consequently leading to truncated Pendrin protein. Sequence homology analysis indicated that all the mutations localized at high conservation sites, which emphasized the significance of these mutations on Pendrin spatial organization and function. CONCLUSION: In summary, this study revealed two compound heterozygous mutations (c.1174A>T/c.1181delTCT; c.919- 2A>G/c.1023insC) in Pendrin protein, which might account for the deafness of the two probands clinically diagnosed with EVA. Thus this study contributes to improve understanding of the causes of hearing loss associated with EVA and develop a more scientific screening strategy for deafness.

【Objective】 To investigate the significance of granulocyte macrophage colony-stimulating factor (GM-CSF), nerve growth factor (NGF) and interleukin-17 (IL-17) in the prostate tissue of rats with experimental autoimmune prostatitis(EAP). 【Methods】 EAP rat models were established and divided into control group, EAP group, anti-GM-CSF group (blocking control group) and anti-GM-CSFEAP group (blocking EAP group). Pain behaviors were tested. The pathological changes were observed with HE staining. The mRNA and protein expressions of GM-CSF, NGF and IL-17 were detected with RT-PCR and Western blot. 【Results】 Pain test showed the anti-GM-CSF group had less chronic pelvic pain than the EAP group. HE staining showed the anti-GM-CSF group had less tissue inflammatory response. The EAP inflammation score was higher in the control group than in the anti-GM-CSF group. Immunohistochemistry showed GM-CSF was positive in the EAP group (mainly in the nucleus). RT-PCR and Western blot results showed the mRNA and protein expressions of IL-17 and NGF significantly decreased 50 days after EAP in the anti-GM-CSF group. 【Conclusion】 Increased expressions of GM-CSF, NGF and IL-17 in prostate tissue of EAP rats may be important inflammatory mediators of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS);decreased expressions of NGF and IL-17 after resistance against GM-CSF indicate that GM-CSF may be a potential therapeutic target for CP/CPPS.
