Objective To investigate the differences in efficacy and safety in the treatment of patients with cerebral palsy at different grades of the Gross Motor Function Classification System (GMFCS) by selective posterior rhizotomy (SPR). Methods Relevant literatures on SPR treatment for cerebral palsy were retrieved from Pubmed, Embase, Web of Science, China Biology Medicine disc, China National Knowledge Infrastructure (CNKI), Wanfang Database, and VIP Database. Clinical trials on SPR treatment for cerebral palsy were included for Meta-analysis. At least two researchers independently screened the literatures, extracted data, and assessed the quality of the literatures. Data analysis was performed by Review Manager 5.4 software. Results A total of 2, 726 literatures were retrieved, and 8 literatures were finally included after screening. The results of the Meta-analysis showed that the gross motor function and self-care ability of patients with cerebral palsy at all GMFCS grades improved significantly after surgery, and muscle tone decreased significantly after surgery (P < 0.05). In comparison of the improvement in gross motor function before and after SPR, patients with grades Ⅱ and Ⅲ of GMFCS benefited the most, followed by those with grade Ⅰ, and those with grades Ⅳ and V benefited less. In terms of improving self-care ability, patients with grade Ⅰ benefited the most, followed by those with grade Ⅲ, and those with grades Ⅱ and IV benefited less. No significant adverse reactions were reported in previous literatures. Conclusion SPR is a relatively safe and effective treatment option for patients with cerebral palsy. Patients at grades Ⅱ and Ⅲ of GMFCS benefit the most from SPR, and patients at grades Ⅳ and V with poor preoperative physical status can also benefit from SPR.

Objective To explore the risk factors for lower limb venous thrombosis in patients after craniocerebral surgery,and establish a prognostic nomogram for the occurrence of lower limb venous thrombosis.Methods A total of 427 patients who underwent craniotomy for craniocerebral trauma and met the inclusion criteria in the First People's Hospital of Taicang from January 2018 to December 2020 were collected as training group,and the nomogram was drawn and verified internally.And 106 patients who underwent surgery from January 2021 to June 2021 were used as test group,and the model was externally verified set.The nomogram was established and internally validated with the data of the training group,and externally validated with the data of the test group.For the training group,multivariate Logistic regression analysis was performed by including all variables with P＜0.05 in univariate analysis,and established the prognostic nomogram by R software.In the training group and the test group,the performance of the nomogram was verified by C-index,calibration chart and decision curve analysis respectively.Results In the training group of 427 people,107 had lower limb venous thrombosis,with an incidence rate of 25.1％.Among the 106 people in the test group,33 developed lower limb venous thrombosis,with an incidence rate of 31.1％.Multivariate logistic regression analysis showed that age,lower preoperative GCS score,postoperative lower limb muscle strength＜3,hypertension,and diabetes were independent risk factors for the occurrence of lower limb vein thrombosis after craniocerebral surgery.The C-index of this nomogram in the training group and the test group was 0.837(95％CI:0.796-0.878)and 0.933(95％CI:0.886-0.979),respectively.Conclusion The nomogram including the age,preoperative GCS score,postoperative lower limb muscle strength＜3,hypertension,and diabetes can predict the probability of lower limb vein thrombosis after craniocerebral surgery with convenient discrimination and clinical utility.

During the progression of heart failure(HF),abnormal transduction of the transforming growth factor-β(TGF-β)/Smads signaling pathway is important mechanism of myocardial fibrosis(MF)in HF.TGF-β,a key factor in MF,is in an overexpression state in the process of MF in HF,and Smads is a major effector downstream of TGF-β.The TGF-β/Smads pathway induces abnormal proliferation of myofibroblasts,aggravates myocardial extracellular matrix deposition,and reduces the ability of the cardiac tissues to resist fibrosis,which plays a complex role in the pathogenesis of MF in HF.Traditional Chinese medicine(TCM)has the efficacy of unequivocal inhibiting myocardial collagen deposition,anti-MF,protecting the myocardium and improving cardiac function in the prevention and treatment of MF in HF and so on,and the TGF-β/Smads pathway is one of the key pathways through which TCM monomers,TCM combinations,and proprietary medicines can exert their cardioprotective effects on the HF.This paper reviews the existing experimental research results of TCM intervening in the TGF-β/Smads pathway for the treatment of MF in HF over the past 10 years,with a view to providing theoretical basis for the prevention and treatment of HF MF well as the development and of new drugs.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

OBJECTIVE: In order to distinguish the traditional Chinese medicine Bupleurum falcatum and its adulterants effectively and develop a better understanding of the factors affecting synonymous codon usage, codon usage patterns of chloroplast genome, we determine the complete chloroplast (cp) genome of B. falcatum and clarify the main factors that influence codon usage patterns of 78 genes in B. falcatum chloroplast genome. METHODS: The total genomic DNA of fresh leaves from a single individual of B. falcatum was extracted with EASYspin plus Total DNA Isolation Kit and 2 μg genome DNA was sequenced using Illumina Hiseq 2500 Sequencing Platform. The cp genome of B. falcatum was reconstructed with MITObim v1.8 and annotated in the program CPGAVAS2 with default parameters. Python script and Codon W were used to calculate the codon usage bias parameters. RESULTS: The full length of B. falcatum cp genome was 155 851 bp, 132 different genes were annotated in this cp genome containing 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. The codon usage models tended to use A/T-ending codons. The neutrality plot, ENC plot, PR2-Bias plot and correspondence analysis showed that both compositional constraint under selection and mutation could affect the codon usage models in B. falcatum cp genome. Furthermore, three optimal codons were identified and most of these three optimal codons ended with G/U. CONCLUSION The cp genome of B. falcatum has been characterized and the codon usage bias in B. falcatum cp genome is influenced by natural selection, mutation pressure and nucleotide composition. The results will provide much more barcode information for species discrimination and lay a foundation for future research on codon optimization of exogenous genes, genetic engineering and molecular evolution in B. falcatum.

【Objective】 To evaluate the efficacy and weight of sellar floor repair techniques such as different dura suture, bone reconstruction, and pedicled nasoseptal flap (PNSF) on the skull base reconstruction of medium and high flow cerebrospinal fluid leakage during endonasal endoscopic pituitary adenoma surgery. 【Methods】 We collected the data of Grade 2-3 cerebrospinal fluid leakage (Kelly grade) during endonasal endoscopic pituitary adenoma resection in our hospital from January 2015 to April 2021. Multiple reconstruction techniques such as dura suture, bone reconstruction and PNSF, and related factors such as age, sex, body mass index (BMI), diabetes, tumor size and diameter of diaphragmatic defect were recorded and introduced to multivariate regression to analyze the effects of the above factors on the duration of postoperative cerebrospinal fluid rhinorrhea and bed rest time, with a special focus on the weight priority of dura suture, bone reconstruction, and PNSF. 【Results】 A total of 281 patients were included, with the average age of (47±12.6) years, males accounting for 52.6%. There were 93 cases of PNSF, 268 cases of bone reconstruction, 109 cases of dura anchor suture, 50 cases of patch suture, and 122 cases without suture. The results of multivariate analysis indicated that the application of PNSF, bone reconstruction, and dura suture significantly reduced postoperative rhinorrhea time [reduced by 18.524, 35.876, and 16.983/19.791 (anchor suture/patch suture) hours, respectively; all P<0.001] and bed time [reduced by 16.797, 58.233, and 18.063/21.604 (anchor suture/patch suture) hours, respectively; all P<0.001], and there was no significant difference between anchor suture and patch suture. The weight of the standardized coefficient in reducing postoperative rhinorrhea time was dura suture>PNSF>bone reconstruction [Standard β=0.211/0.207 (anchor suture/patch suture)>0.200>0.165]. The weight of reducing bed time was bone reconstruction >dura suture > PNSF [Standard β=0.239>0.206/0.210 (anchor suture/patch suture) >0.164]. After stabilizing the learning curve in 25-30 cases, the average time for bone reconstruction was (3.9±0.4) minutes. After stabilizing learning curve in 30-40 cases, the dura suture technique took an average of (3.7±0.3) minutes per stitch, (3.7±1.0) stitches per case, and (13.6±2.7) minutes of total time consumption per case. 【Conclusion】 Dural anchoring and patching suture can both effectively shorten the duration of cerebrospinal fluid rhinorrhea and bed rest time. Bone reconstruction significantly improves the stability of reconstruction, especially in prompting patients’ early disengagement of bed rest. Moreover, the learning curves of the above two methods are economical and reasonable, and their weight is close to or even exceeds that of PNSF. Therefore, they can be an effective supplement or even substitute for PNSF.

Objective: To evaluate the transmissibility of 2019-nCoV Omicron variant under the current prevention and control strategy in Beijing, and provide evidence for the prevention and control of COVID-19. Methods: The information of 78 Omicron variant infection cases involved in clear transmission chains in Beijing during 7-25 March, 2022 were collected, the incubation period and serial interval of the disease were fitted by using Gamma and Weibull distribution. Markov Chain Monte Carlo approach was used to estimate the time-varying reproduction number (R_t). Results: The median of the incubation period (Q₁, Q₃) of Omicron variant infection was 4.0 (3.0, 6.0) days, and the serial interval was 3.0 (2.0, 5.0) days. The median of the serial interval (Q₁, Q₃) was 2.0 (1.0, 4.0) days in unvaccinated cases and 4.0 (2.0, 6.0) days in vaccinated cases (Z=-2.12, P=0.034), and 2.0 (1.5, 3.0) days in children and 4.0 (2.0, 6.0) days in adults, respectively (Z=-2.02,P=0.044), the differences were significant. The mean of R_t was estimated to be 4.98 (95%CI: 2.22-9.04) for Omicron variant in this epidemic. Conclusion: Omicron variant has stronger transmissibility compared with Delta variant. It is necessary to strengthen the routine prevention and control COVID-19, promote the vaccination and pay close attention to susceptible population, such as children.

Objective:To investigate the kinetic metrics of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 in pancreatic cancers and normal organs by using total-body PET dynamic imaging. Methods:From December 2020 to December 2021, 68Ga-FAPI-04 total-body PET/CT dynamic imaging were performed on 6 pancreatic cancer patients (3 males, 3 females, median age 55.5 years) in Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University. Images were respectively analyzed. Manual delineations of volume of interests (VOIs) on multiple normal organs and pathological lesions were performed and time-to-activity curves (TACs) were generated. A reversible two-tissue compartment model (2TCM) was fitted for each tissue TAC. Rate constants including K1, k2, k3 and k4, and the total volume of distribution ( Vt) were obtained and compared by tissue types. Wilcoxon rank sum test and Spearman correlation analysis were used for data analysis. Results:Kinetic metrics varied significantly among normal organs and pancreatic cancer lesions ( z values: 2.00-1 240.00, all P<0.05). The highest K1 among lesions was observed in primary tumor (0.30 min -1), which was observed in the spleen (1.42 min -1) among normal organs. The highest k2 among lesions was observed in peritoneal metastases (0.24 min -1), which was observed in the spleen (2.59 min -1) among normal organs. Primary tumor showed the highest k3 of 0.17 min -1 among lesions, and the pancreas had the highest k3 of 0.16 min -1 among normal organs. Primary tumor had the highest k4 of 0.03 min -1 among lesions, and the heart, lungs, parotid glands had high k4(0.06 min -1) among normal organs. Vt were higher in pathological lesions compared to normal organs, with the highest in primary tumor (13.78 ml/cm 3). There were correlations between Vt in lesions and SUV mean( rs=0.86, P<0.001) or SUV max ( rs=0.77, P<0.001). Conclusion:The rate constants including K1, k2, k3 and k4, and Vt of 68Ga-FAPI-04 vary among normal organs and lesions.
