Objective:To compare the short-term efficacy and the safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTNs).Methods:This prospective randomized controlled trial, performed from December 2019 to September 2021, included 36 patients with solid or predominantly solid BTNs who met the eligibility criteria and provided written informed consent at the Nanjing sub-center (Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine). Patients were assigned to either the MWA group or the RFA group (18 patients in each group) at a ratio of 1∶1 using a block randomization design and allocation concealment using sealed envelope randomization. The independent-sample t-test and χ2 test were used to compare the volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates at 1, 3, and 6 months after treatment between the two groups. Results:The clinical characteristics of the two groups of patients were comparable. After ablation, the nodule volume was significantly reduced in both groups. At 1, 3, and 6 months, there was no significant difference in the volume between the two groups (all P>0.05). At 3 months, the RFA group had a larger VRRs than that in the MWA group (62.08%±12.46% vs. 46.90%±23.16%, t=-2.45, P=0.021). However, at 1 and 6 months, no statistical significance was observed (both P>0.05). No significant difference was observed in the effective rates at the last follow-up (14/18 vs. 18/18, P=0.104). However, the RFA group had a lower cosmetic score than that in the MWA group (1.78±0.43 vs. 2.17±0.51, t=-2.47, P=0.019). There was no statistically significant difference in the complication rates between the two groups (all P>0.05). Conclusions:Both MWA and RFA were effective and safe treatments for BTNs, with no significant differences in short-term efficacy and safety. In addition, the RFA group showed slightly more favorable outcomes than the MWA group in terms of cosmetic improvement.

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

ObjectiveTo explore the mechanism of Didangtang （DDT） against the inflammatory cascade triggered by foam cell pyroptosis in high-glucose environment. MethodOxidized low density lipoprotein （ox-LDL， 100 mg·L^-1） was used to induce pyroptosis of foam cells. The control group （5.5 mmol·L^-1 glucose）， foam cell group （100 mg·L^-1 ox-LDL）， high-glucose group （33.3 mmol·L^-1 glucose）， DDT group （10% DDT-containing serum）， and NOD-like receptor family pyrin domain-containing 3 （NLRP3） inhibitor group （MCC950， 10 nmmol·L^-1） were designed. The cell membrane damage was observed by lactate dehydrogenase （LDH） release assay. The expression of cysteinyl aspartate-specific proteinase-1 （Caspase-1） was detected by immunofluorescence method， and expression of key proteins NLRP3， Caspase-1， gastermin D （GSDMD）， interleukin-1β （IL-1β）， and interleukin-18 （IL-18） in the pyroptosis pathway was determined by Western blot. The release of IL-18 and IL-1β， monocyte chemoattractant protein-1 （MCP-1）， and tumor necrosis factor α （TNF-α） in cell supernatant was measured by enzyme-linked immunosorbent assay （ELISA）. ResultThe expression of NLRP3， Caspase-1， and GSDMD was up-regulated （P<0.01） and the release of IL-1β， IL-18， MCP-1， IL-1α， and TNF-α was increased （P<0.01） in foam cell group compared with those in the control group. The expression of NLRP3， Caspase-1， and GSDMD was higher （P<0.01） and the release of inflammatory factors was more （P<0.01） in the high-glucose group than in the foam cell group. DDT and MCC950 can inhibit expression of NLRP3， Caspase-1， GSDMD and reduce the release of IL-1β， IL-18， MCP-1， IL-1α， and TNF-α. ConclusionDDT can suppress the pyroptosis of foam cells induced by NLRP3/Caspase-1 pathway in high-glucose environment and thereby alleviate the inflammatory cascade.

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. The systemic antitumor therapy of advanced NSCLC has undergone renovations of chemotherapy, targeted therapy and immunotherapy, which results in greatly improved survival for patients with advanced NSCLC. Immune checkpoint inhibitors (ICIs), especially targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1), has changed the treatment paradigm of NSCLC. ICIs have become the standard treatment for advanced NSCLC without epidermal growth factor receptor(EGFR) mutation or anaplastic lymphomakinase(ALK) translocation in the first- or second-line setting, and for locally advanced NSCLC following concurrent radiotherapy and chemotherapy. ICIs are also promising in adjuvant/neoadjuvant therapy. More and more ICIs have been approved domestically for the treatment of NSCLC. Led by the NSCLC expert committee of Chinese Society of Clinical Oncology (CSCO), this consensus was developed and updated based on thoroughly reviewing domestic and foreign literatures, clinical trial data, systematic reviews, experts' discussion and the consensus(2019 version). This consensus will aid domestic clinicians in the treatment of NSCLC with ICIs.

OBJECTIVE: To compare the clinical effects of ultrasonic subgingival debridement and ultrasonic subgingival debridement combined with manual root planing on severe periodontitis and then to investigate the necessity and significance of manual root planing. METHODS: Twenty-three patients with severe periodontitis participated in this split-mouth randomized-controlled clinical trial. Baseline examination and randomization were performed after supragingival scaling: each of the upper and lower jaws had a quadrant as the test group treated with ultrasonic subgingival debridement combined with manual root planing, whereas the other two quadrants were the control group treated with ultrasonic subgingival debridement. Treatment of each patient was at intervals of one week and completed in two visits. Clinical indicators concerning probing depth (PD), clinical attachment loss (CAL) and bleeding index (BI) were recorded at baseline and 1 month, 3 months, 6 months after treatment. RESULTS: There was no significant difference of periodontal indicators between the test group and the control group at baseline. Both the test group and control group resulted in significant improvement of PD, CAL and BI. One and three months after treatment, reduction of PD in the test group was higher than that in the control group [1 month: (2.13±1.31) mm vs. (1.79±1.33) mm, P<0.01; 3 months: (2.46±1.33) mm vs. (2.17±1.38) mm, P<0.01] and reduction of CAL in the test group was higher than that in the control group [1 month: (1.89±2.03) mm vs. (1.65±1.93) mm, P<0.01; 3 months: (2.03±2.05) mm vs. (1.83±1.97) mm, P<0.05]. Six months after treatment, PD in the test group and the control group decreased by (2.52±1.40) mm and (2.35±1.37) mm respectively, and the improvement in the test group was significantly better than that in the control group (P<0.01). CAL in the test group and the control group decreased by (1.89±2.14) mm and (1.77±2.00) mm respectively, and there was no statistical difference between the groups. There was no significant difference in the changes of BI between the two groups 1, 3 and 6 months after treatment. CONCLUSION Ultrasonic subgingival debridement combined with manual root planing has more reduction in PD and CAL compared with ultrasonic subgingival debridement. Therefore, it is still necessary to use manual instruments for root planing following ultrasonic subgingival debridement.

OBJECTIVE: To explore the clinical effect of acupoint puncture combined with Ilizarov technique in the treatment of knee osteoarthritis in the elderly. METHODS: From March 2015 to February 2016, 76 patients with primary knee osteoarthritis were treated with tibial osteotomy acupoint puncture grouop and Ilizarov technique anatomical puncture group, including 24 males and 52 females, aged 56 to 75 years old with an average of 61.4 years old, and a course of 3 to 17 years with an average of 5.2 years. Among them, 38 cases were treated with external fixation of acupoint puncture needle and 38 cases were treated with external fixation of anatomical puncture needle. Preoperative full-length X-ray of both lower limbs showed tibial varus deformity, narrowing of medial knee joint space and enlargement of lateral knee joint space. The force line of the affected knee and lower limb was moved inward by body surface measurement, and the KSS knee function score was decreased. Symptoms included medial knee pain, flexion and extension, and conservative treatment for more than 2 years. RESULTS: The lower limb force lines of both groups were corrected and the osteotomy ends healed well. No nonunion of osteotomy, inadequate correction of lower limbs or recurrence of deformity were found. Seventy-five patients were followed up for 3, 6, 12 and 24 months after operation. There was no significant difference in knee joint mobility between the two groups before operation and on 6, 12, 24 months after operation(=1.346, >0.05). There were significant difference in KSS pain and total score between the two groups at 3 months after operation, acupoint puncture group was better than anatomical puncture group(<0.05); there was no significant difference in KSS score at 12 months after operation(>0.05). CONCLUSIONS The acupoint puncture group formed a potential acupuncture effect in the acupoint area by continuously tightening the steel needle on Ilizarov ring external fixator during the post-operative adjustment. Within three months after wearing external fixator, the knee pain symptoms of knee osteoarthritis were relieved rapidly, continuously and effectively, which was significantly better than that of the anatomical puncture group.
