Objective:To compare the efficacy of the detection kit based on MicroDrop microdroplet digital PCR platform that can identify mycoplasma pneumonia and common drug-resistance mutation,and throughout targeted next-generation sequencing(tNGS)in detecting common drug-resistance mutations of mycoplasma pneumonia.Methods:A total of 300 samples of clinical respiratory tract of pneumonia inpatients at Guangdong Provincial People's Hospital between 2023 and 2024 were collected.Both the detection kit for drug-resistance mutation of mycoplasma pneumoniae and the tNGS method were employed to detect drug-resistance mutation genes.For samples with inconsistent results,Sanger sequencing was used for verification.Results:For the 300 samples,the detection rates of positive mycoplasma pneumonia of the detection kit for drug-resistance mutation of mycoplasma pneumoniae and the tNGS method were respectively 87.00%and 78.67%,with a Kappa value of 0.711,indicating a relatively high level of agreement between the two methods.Among 25 samples with inconsistent results,Sanger sequencing was employed for validation.The results revealed that for samples with low-frequency gene mutations,the reagent kit maintained reliable detection capability,whereas tNGS exhibited missed detections.Thus,the reagent kit demonstrates superior performance in detecting low-frequency mutation samples.Conclusion:The detection rate of low-frequency mutation samples by the digital PCR-based mycoplasma pneumoniae drug-resistance mutation detection kit is higher than that of the tNGS method.This approach helps enhance the accuracy of detection results,providing a rapid and precise means of detecting drug-resistance genes for clinical diagnosis and treatment.

Due to the constraints of the surgical environment and operational space,laparoscopic surgical instruments employ wire-driven mechanisms.However,factors such as wire rigidity,hysteresis,and motor drive limitations result in the end-effector accuracy of surgical instruments failing to meet ideal requirements.To address the shortcomings of existing multi-degree-of-freedom laparoscopic surgical instruments in achieving end-effector precision,a motion compensation algorithm based on the Autogluon algorithm for a 4-degree-freedom laparoscopic surgical instrument is proposed.A single-degree-of-freedom surgical instrument driven by wire ropes was constructed,and machine learning was utilized to estimate the end-effector position.This estimated position served as a feedback compensation condition to control the end-effector of the surgical instrument.To validate the correctness of this method,it was compared with approaches such as neural networks,linear regression,decision trees,Gaussian processes,and support vector machines.The results demonstrated that the proposed method achieved the smallest mean squared error,maximum error,and mean absolute error,thereby verifying its effectiveness.

Objective:To compare the clinical effect of deproteinized calf blood extract (DCBE) eye drops and 0.3% sodium hyaluronate eye drops in the treatment of diabetic cataract patients with dry eye after phacoemulsification.Methods:A randomized controlled study was performed.A total of 112 patients (116 eyes) with type Ⅱ diabetes combined with cataract and dry eye who underwent phacoemulsification in the Eye Hospital of Shandong First Medical University from January 2022 to September 2022 were selected.Patients were divided into DCBE group (49 cases, 51 eyes) and sodium hyaluronate group (63 cases, 65 eyes) by the random number table method.Patients received DCBE eye drops and 0.3% sodium hyaluronate eye drops after surgery according to grouping.Preoperative and postoperative 1 week, 1 month subjective symptoms of dry eye, corneal edema grade, tear film breakup time (TBUT), corneal fluorescein staining (CFS) and Schirmer Ⅰ test (SⅠt) results were recorded and compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye Hospital of Shandong First Medical University (No.SDSYKYY202112-1).Written informed consent was obtained from each subject.Results:There were significant differences in dry eye symptom score, TBUT and SⅠt at different time points between before and after surgery ( Ftime=323.202, 102.771, 151.876; all P<0.001).Dry eye symptom score decreased and SⅠt increased in the two groups at 1 week and 1 month after surgery compared with before surgery, and the differences were statistically significant (all P<0.017).TBUT was longer at 1 week and 1 month after surgery compared with before surgery in the DCBE group, and TBUT at 1 month after surgery was longer than that before surgery in the sodium hyaluronate group, and the differences were statistically significant (all P<0.017).There were statistically significant differences in CFS scores between the two groups at different time points before and after surgery ( Fgroup=5.391, P=0.022; Ftime=142.402, P<0.001).The CFS scores of both groups at 1 week and 1 month after surgery were lower than those before surgery, and CFS scores in the DCBE group were lower than those in the sodium hyaluronate group, with statistically significant differences (all P<0.017).One week after surgery, the proportion of patients with corneal edema in the DCBE group was 5.9%(3/51), which was significantly lower than 20.0%(13/65) in the sodium hyaluronate group ( χ2=4.790, P=0.029). Conclusions:DCBE eye drops can promote corneal repair, stabilize tear film and improve dry eye discomfort in early postoperative period in diabetic cataract, and its overall effect is better than 0.3% sodium hyaluronate eye drops.

A 11-year old female patient with severe thalassemia, receipt a lentivirus-based cell and gene therapy (CGT) therapy in Shenzhen Children′s Hosptial on July 27th, 2021. At the two follow-up visits after discharge, patient were continuously tested positive for HIV screening through HIV Ag/Ab Combo assay (chemiluminescence Immunoassay), and the viral load results of HIV-1 nucleic acid testing (NAT) were both>5 000 copies/ml. The patient can be diagnosed with HIV infection according to the National Guideline for Detection of HIV/AIDS(2020 Revised Edition). The thorough investigation findings and supplementary experiment results indicated that the false-positive HIV-1 NAT results was caused by cross-reactivity between the target sites detected by conventional HIV-1 NAT reagents and the lentiviral vectors fragments integrated into the genome of patient′s hematopoietic stem/progenitor cells. In conclusion, it is important for laboratories to select appropriate HIV-1 NAT testing platforms which won′t cause cross-reactivity for the testing of samples from patients who have been treated with HIV-derived vectors. It is also recommended to design and develop NAT testing platforms with multiple target regions labeled by different fluorescents for HIV NAT supplementation experiment to reduce the risk of false-positive diagnoses of HIV infection.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.
