AIM: To analyze the correlation between ocular surface status and serum lipids in patients with meibomian gland dysfunction(MGD)during pregnancy, and to provide new ideas for the management and treatment of MGD during pregnancy.METHODS: Totally 120 pregnant women(240 eyes)treated in our hospital from May 2021 to May 2022 were selected and they were divided into MGD group(60 cases, 120 eyes)and control group(60 cases, 120 eyes)according to the presence or absence of MGD. All subjects received the ocular surface disease index scores(OSDI)and underwent examinations of meibomian gland morphology and function, tear film and blood lipid.RESULTS: The scores of OSDI, the related indexes of meibomian gland, corneal fluorescein staining(FL)scores, total cholesterol(TC), triglyceride(TG)and low density lipoprotein-cholesterol(LDL-C)in the MGD group were significantly higher than those in the control group(P<0.05). The scores of fluorescein breakup time(FBUT), Schirmer Ⅰ test(SIt)and high-density lipoprotein cholesterol(HDL-C)in the MGD group were significantly lower than those in the control group(P<0.05). Correlation analysis showed that the scores of TG, TC, LDL-C were negatively correlated with the values of FBUT(rs =-0.702, -0.647, -0.710, all P<0.001).CONCLUSION: The level of blood lipids in pregnant patients with MGD is significantly increased, and the levels of TC, TG and LDL-C may be related to the stability of tear film.

Malignant pleural mesothelioma(MPM)is a rare cancer with high malignancy and aggressiveness on the pleural,caused by the following risk factors including asbestos inhalation,genetic factors,and genetic mutation.The pres-ent chemotherapy,antiangiogenic therapy,and immunotherapy methods are ineffective and the survival time of patients is very short.There is an urgent need to find potential therapeutic targets for MPM.At present,it has been found the following types of targets:gene mutation targets such as BRCA associated protein 1(BAP1)and cyclin-dependent kinase 2A(CDKN2A);epigenetic targets such as lysine(K)-specific demethylase 4A(KDM4A)and lysine-specific demethylase 1(LSD1),and signal protein targets such as glucose-regulated protein 78(GRP78)and signal transducer and activator of transcription 3(STAT3).So far,available clinical trials include phase Ⅱ clinical trials of histone methyltransferase inhibitor Tazemetostat,poly(ADP-ribose)polymerase(PARP)inhibitor Rucaparib and cyclin-dependent kinases 4 and 6(CDK4/6)inhibitor Abemaciclib,as well as phase Ⅰ clinical trials of mesothelin-targeting chimeric antigen receptor T-cell immunotherapy(CAR-T)cell injection in the thoracic cavity and TEA domain family member(TEAD)inhibitor VT3989 and IK-930,and the results of these trials have showed certain clinical efficacy.

Objective To explore the potential categories of self-efficacy in patients with rheumatoid arthritis(RA),analyze their influencing factors,and provide references for the development of personalized care measures.Methods Patients with RA who visited the rheumatology and immunology outpatient department of a tertiary hospital in Changzhou from March 2022 to March 2023 were selected.A general information questionnaire,the Chinese version of the Rheumatoid Arthritis Self-Efficacy Scale(C-RASE),and Compliance Questionnaire Rheumatology(CQR)were used to investigate RA patients.Latent class analysis was used to classify self-efficacy,and logistic regression analysis was conducted to explore the influencing factors of self-efficacy.Results A total of 219 subjects were included in the survey.The score of C-RASE was(100.68±12.64).The self-efficacy of RA patients was divided into a high efficacy-low support group(105.18±10.18),a moderate efficacy-diverse needs group(93.21±4.16),and a low efficacy-high fatigue group(84.07±13.96).Logistic regression analysis showed that disease duration(OR=1.062,P=0.024),education(OR=5.405,P=0.036;OR=12.347,P=0.021),and erythrocyte sedimentation rate(OR=1.019,P=0.020;OR=1.019,P=0.027)were factors affecting patients'self-efficacy.The treatment compliance scores of the 3 latent class categories(F=10.902,P＜0.001)and the rate of good treatment compliance(x2=16.053,P＜0.001)were statistically significant.Conclusion RA patients exhibit significant heterogeneity in their self-efficacy levels,and there are variations in treatment adherence among patients in different self-efficacy categories.Nurses should prioritize the attention towards the population groups with moderate efficacy-diverse needs,as well as the groups with low efficacy-high fatigue,implementing cognitive behavioral interventions to assist them in setting clear goals and providing specific plans and guidance to improve their health outcomes.

Objective To investigate the effect of subanesthetic dose of esketamine for postoperative analgesia on early recovery in elderly patients undergoing laparoscopic radical resection of rectal cancer.Methods Elderly patients undergoing laparoscopic radical resection of rectal cancer were included,and they were divided into the AS group(61 cases received esketamine for intravenous self-controlled analgesia)and the SF group(60 cases received sufentanil for intravenous self-controlled analgesia)by random number table method.The operation time,intraoperative infusion volume,urine output,intraoperative blood loss,postoperative rescue analgesia,tramadol dosage and the number of patient controlled intravenous analgesia(PCIA)compressions within 48 hours after surgery,postoperative visual analogue scale(VAS)score,Ramsay sedation score,first ambulation time after surgery,first gas passage time after surgery,and first feeding time after surgery were compared between the two groups.The occurrence of adverse reactions in the two groups was recorded.The levels of interleukin-6(IL-6)and C-reactive protein(CRP)immediately after surgery,24 hours and 72 hours after surgery in the two groups were detected by ELISA.The scores of anxiety and depression 3 days,1 week and 1 month after surgery were compared between the two groups.Results There was no significant difference in the operation time,intraoperative infusion volume,urine output,intraoperative blood loss,postoperative rescue analgesia,tramadol dosage or PCIA compressions within 48 hours after surgery between the two groups(P＞0.05).The levels of IL-6 and CRP gradually increased immediately after surgery and 24 hours and 72 hours after surgery in the two groups(P＜0.05),and the levels of IL-6 and CRP 24 hours and 72 hours after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).The first ambulation time after surgery,first gas passage time after surgery,and first feeding time after surgery in the AS group were earlier than those in the SF group(P＜0.05).The incidences of nausea,vomiting and dizziness in the AS group were significantly lower than those in the SF group(P＜0.05).The levels of IL-6 and CRP 24 hours and 72 hours after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).The scores of anxiety and depression 3 days and 1 week after surgery in the AS group were significantly lower than those in the SF group(P＜0.05).Conclusion Subanesthetic dose of esketamine for postoperative analgesia can alleviate short-term postoperative anxiety and depression in elderly patients undergoing laparoscopic radical resection of rectal cancer,relieve postoperative pain and inflammatory responses and have a low incidence of adverse reactions,which contribute to early recovery of patients.

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.

Objective:To analyze the clinical characteristics of different types of anomalous origin of the coronary artery.Methods:A case-series study was conducted.Based on the clinical data of children diagnosed with anomalous origin of the coronary artery at Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine from January 2013 to January 2023, the diseases of different types of anomalous origin of the coronary artery were summarized.Results:A total of 177 children with anomalous origin of the coronary artery were treated.Among them, 122 children developed the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), including 54 males and 68 females, with a median age of 1.2 years; 6 children developed the anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA), including 3 males and 3 females, with a median age of 4.3 years; 9 children developed the anomalous left coronary artery from the right coronary sinus (ALCA), including 6 males and 3 females, with a median age of 9.5 years; 40 children developed the anomalous right coronary artery from the left coronary sinus (ARCA), including 24 males and 16 females, with a median age of 7.7 years.Most children diagnosed with ALCAPA had onset within 1 year of age, with chronic heart failure as the main manifestation, and young children were often accompanied by severe mitral regurgitation.A total of 111 children underwent surgery, and 11 children died.Six children with ARCAPA had no obvious clinical symptoms and were treated by operation according to the principle of double coronary circulation after diagnosis.Nine children with ALCA started with syncope, chest pain or abdominal pain after exercise.Eight of the children underwent surgical treatment, including 1 who received a heart transplant.Of the 40 children with ARCA, 23 children had clinical manifestations, with chest tightness, syncope, and chest pain after exercise as chief complaints; 16 children were tested positive for treadmill exercise before surgery; and a total of 13 children received surgical treatment.Conclusions:Different types of anomalous origin of the coronary artery vary in severity.The clinical manifestations of the anomalous origin of the left coronary artery are generally serious, and most of such patients have the risk of cardiac insufficiency or sudden death.Once diagnosed, surgical treatment should be performed timely.The clinical manifestations of the anomalous origin of the right coronary artery are relatively mild, and only a few may have serious consequences, which are usually treated according to the principle of individualization or double coronary circulation.

OBJECTIVE: To retrospectively analyze the clinical efficacy of anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex repair and ACL reconstruction combined with ALL reconstruction in the treatment of anterior cruciate ligament injuries with high-grade pivot shift. METHODS: From January 2018 to June 2022, 49 patients combined ACL and ALL injuries with high-grade pivot shift were retrospectively studied from three hospitals, 29 of them underwent ACL reconstruction with anterolateral complex repair (repair group), including 23 males and 6 females with an average age of (27.5±4.8) years old, ranged from 20 to 37 years old;the injured sides were 13 on the left and 16 on the right, and 11 patients were suffered with meniscus injury. The other 20 patients underwent ACL and ALL reconstruction (reconstruction group) including 17 males and 3 females with the mean age of (27.1±4.5) years old, ranged from 20 to 38 years old;the injured sides were 8 on the left and 12 on the right, and 6 patients were suffered with meniscus injury. Knee stability (pivot shift test, KT-2000), range of motion, knee function (Lysholm scoring scale, Cincinnati sports activity scale (CSAS) scoring scale, and Tegner activity level score between two groups were compared. RESULTS: A total of 49 patients were followed up, the repair group receiving 13 to 20(15.3±1.8) months and the reconstruction group receiving 12 to 21(16.0±2.2) months. There was no statistically significant difference in the preoperative pivot shift test grading distribution between two groups (P>0.05). At the last postoperative follow-up, there were 24 patients with grade 0 and 5 patients with grade 1 in the repair group, and there were 18 patients with grade 0 and 2 patients with grade 1 in the reconstruction group, there is no significant difference in the distribution of axial shift test grading between two groups(P>0.05). The preoperative KT-2000 tibial displacement of two groups were (9.39±0.77) mm (repair group) and (9.14±0.78) mm (reconstruction group) respectively, with no statistically significant difference (P>0.05). At the final postoperative follow-up, there were 24 patients with KT-2000 tibial displacement <3 mm and 5 patients with 3 to 5 mm in the repair group, while 18 patients with <3 mm and 2 patients with 3 to 5 mm in the reconstruction group, KT-2000 tibial displacement distribution of two groups was no significant difference (P>0.05), but the KT-2000 tibial displacement in the reconstruction group (1.30±0.86) mm was significantly smaller than that in the repair group (1.99±1.11) mm (P<0.05). The final postoperative follow-up range of motion of the contralateral side knee between two groups was no significant difference (P>0.05). The range of motion of the suffering knee in the repair group was less than that in the reconstruction group (P<0.05). There was no significant difference in preoperative Lysholm and CSAS scores between two groups (P>0.05). At the final postoperative follow-up, both groups showed significant improvement in Lysholm and CSAS scores, while the Lysholm and CSAS scores of the reconstruction group were better than those of the repair group, and the difference was statistically significant (P<0.05). Significant differences was found in Tegner scores between two groups, which 16 patients in the repair group returned to their pre-injury activity level, and 17 patients in the reconstruction group returned to their pre-injury level (P<0.05). CONCLUSION Compared to anterolateral complex repair, combined ACL and ALL reconstruction in the treatment of ACL injuries with high-grade pivot shift results in better knee joint function and stability. This is advantageous in reducing the risk of ACL reconstruction failure.

Sleep-wake disorder is one of the most common nonmotor symptoms of Parkinson's disease (PD). Melatonin has the potential to improve sleep-wake disorder, but its mechanism of action is still unclear. Our data showed that melatonin only improved the motor and sleep-wake behavior of a zebrafish PD model when melatonin receptor 1 was present. Thus, we explored the underlying mechanisms by applying a rotenone model. After the PD zebrafish model was induced by 10 nmol/L rotenone, the motor and sleep-wake behavior were assessed. In situ hybridization and real-time quantitative PCR were used to detect the expression of melatonin receptors and lipid-metabolism-related genes. In the PD model, we found abnormal lipid metabolism, which was reversed by melatonin. This may be one of the main pathways for improving PD sleep-wake disorder.
