ObjectiveTo explore the distribution and evolution patterns of traditional Chinese medicine （TCM） syndromes and syndrome elements in psoriasis vulgaris （PV）. MethodsLiterature related to TCM syndromes of PV published in databases including China National Knowledge Infrastructure （CNKI）， Wanfang Data Knowledge Service Platform （Wanfang）， VIP Chinese Technology Periodical Database （VIP）， Chinese Biomedical Literature Database （CBM）， PubMed， Embase， and Web of Science from their inception to December 31， 2023， was retrieved. Statistical analysis was conducted on the distribution of TCM syndromes and syndrome elements in the included studies. The data were further categorized into five-year periods to analyze the dynamic changes in syndromes and syndrome elements over time. ResultsA total of 2,853 studies were included， with 5,896 syndrome occurrences. The most common TCM syndromes in PV were blood-heat syndrome （2,167 occurrences， 36.75%）， blood-stasis syndrome （1,219 occurrences， 20.68%）， blood-dryness syndrome （1,124 occurrences， 19.06%）， and damp-heat syndrome （263 occurrences， 4.46%）. The most frequent syndrome categories included blood syndromes （4,680 occurrences， 79.38%） and dampness syndromes （347 occurrences， 5.89%）. The most common syndrome elements related to disease location were blood division （4,874 occurrences， 94.38%） and spleen （99 occurrences， 1.92%）. The most common syndrome elements related to disease nature were blood-heat （2,213 occurrences， 25.96%）， blood-dryness （1,434 occurrences， 16.82%）， and blood-stasis （1,330 occurrences， 15.60%）. Except for the period 1978-1983， blood-heat， blood-stasis， and blood-dryness syndromes consistently ranked among the top three， with their combined proportion showing an overall upward trend （from 67.65% to 81.69%）. The proportion of spleen deficiency with damp obstruction syndrome also increased （from 0.24% to 1.46%）. In terms of syndrome classification， the proportion of blood syndromes showed an overall upward trend （from 67.65% to 83.46%）， ranking first in all periods. The proportion of dampness syndromes showed a general downward trend （from 17.65% to 4.54%）， ranking second after blood syndromes in most periods except for 1994-1998 and 1999-2003. The proportion of spleen-related syndromes showed an overall increase （from 0.24% to 1.85%）. Regarding disease location elements， the proportion of blood division remained stable above 90%， while the proportion of spleen involvement increased （from 0.68% to 3.23%）. As for disease nature elements， blood-heat （from 19.23% to 33.27%） and blood-stasis （from 1.92% to 20.83%） significantly increased， while dampness initially decreased and then slightly increased （from 11.54% to 5.73%）. ConclusionIn the distribution of PV-related TCM syndromes， blood-heat， blood-stasis， and blood-dryness syndromes are the most common. Blood syndromes dominate syndrome classification， with disease location primarily in the blood division and disease nature characterized by blood-heat， blood-stasis， and blood-dryness. Evolutionary trends indicate that blood-heat， blood-stasis， and blood-dryness syndromes remain predominant and are increasing in proportion， while spleen deficiency with damp obstruction syndrome is also rising. Among syndrome classifications， the proportion of blood syndromes is increasing， dampness syndromes are decreasing， and spleen-related syndromes are on the rise. In terms of syndrome elements， blood division remains dominant， while spleen involvement is increasing. The proportion of blood-heat and blood-stasis is significantly increasing， while dampness first declines and then slightly rebounds. Overall， the mainstream TCM perspective of treating PV based on blood differentiation remains unchanged， with syndrome distribution focusing on blood division. The increasing importance of spleen deficiency and dampness in disease pathogenesis represents a new trend.

Objective:To construct a machine-learning model for predicting the progression of pancreatic cystic lesions (PCLs) based on clinical and CT features, and to evaluate its predictive performance in internal/external testing cohorts.Methods:Baseline clinical and radiological data of 200 PCLs in 177 patients undergoing abdominal thin slice enhanced CT examination at Peking Union Medical College Hospital from July 2014 to December 2022 were retrospectively collected. PCLs were divided into progressive and non-progressive groups according to whether the signs indicated for surgery by the guidelines of the European study group on PCLs were present during three-year follow-up. 200 PCLs were randomly divided into training (150 PCLs) and internal testing cohorts (50 PCLs) at the ratio of 1∶3. 15 PCLs in 14 patients at Jinling Affiliated Hospital of Medical School of Nanjing University from October 2011 to May 2020 were enrolled as external testing cohort. The clinical and CT radiological features were recorded. Multiple feature selection methods and machine-learning models were implemented and combined to identify the optimal machine-learning model based on the 10-fold cross-validation method. Receiver operating characteristics (ROC) curve was drawn and area under curve (AUC) was calculated. The model with the highest AUC was determined as the optimal model. The optimal model's predictive performance was evaluated on testing cohort by calculating AUC, sensitivity, specificity and accuracy. Permutation importance was used to assess the importance of optimal model features. Calibration curves of the optimal model were established to evaluate the model's clinical applicability by Hosmer-Lemeshow test.Results:In training and internal testing cohorts, the progressive and non-progressive groups were significantly different on history of pancreatitis, lesions size, main pancreatic duct diameter and dilation, thick cyst wall, presence of septation and thick septation (all P value <0.05) In internal testing cohort, the two groups were significantly different on gender, lesion calcification and pancreatic atrophy (all P value <0.05). In external testing cohort, the two groups were significantly different on lesions size and pancreatic duct dilation (both P<0.05). The support vector machine (SVM) model based on five features selected by F test (lesion size, thick cyst wall, history of pancreatitis, main pancreatic duct diameter and dilation) achieved the highest AUC of 0.899 during cross-validation. SVM model for predicting the progression of PCLs demonstrated an AUC of 0.909, sensitivity of 82.4%, specificity of 72.7%, and accuracy of 76.0% in the internal testing cohort, and 0.944, 100%, 77.8%, and 86.7% in the external testing cohort. Calibration curved showed that the predicted probability by the model was comparable to the real progression of PCLs. Hosmer-Lemeshow goodness-of-fit test affirmed the model's consistency with actual PCLs progression in testing cohorts. Conclusions:The SVM model based on clinical and CT features can help doctors predict the PCLs progression within three-year follow-up, thus achieving efficient patient management and rational allocation of medical resource.

Objective This study summarized the clinical data of IBD patients receiving upadacitinib treatment in our hospital,and provided more Chinese data to better guide the treatment of upadacitinib in Chinese IBD population.Methods Clinical data of 11 patients with IBD who received upadacitinib treatment at Anhui Provincial Hospital from March 1,2023 to September 8,2024 were retrospectively analyzed.Platelet count,ESR,CRP,disease severity score,endoscopic score,and adverse reactions were compared before treatment,at the 4th and 8th week of treatment,and clinical response rate,clinical response rate,endoscopic response rate,and endoscopic response rate were calculated.SPSS 25.0 software was used for statistical analysis.Results The platelets,ESR and CRP of patients at the 4th and 8th week after upadacitinib treatment were decreased compared with those before treatment,with statistical significance.At the 4th week,the clinical response rate was 72.72％(8/11),the clinical remission rate was 0,the clinical response rate of UC patients was 83.33％(5/6),and the clinical response rate of CD patients was 60％(3/5).At the 8th week of treatment,the clinical response rate was 100％(10/10),the clinical remission rate was 80.00％(8/10),the clinical response rate of UC patients was 100％(6/6),the clinical remission rate of UC patients was 83.33％(5/6),the clinical response rate of CD patients was 100％(4/4),and the clinical remission rate of CD was 75％(3/4).There were no adverse reactions during treatment.Three patients were re-examined by colonoscopy,all of whom were severe UC patients and achieved mucosal healing.Conclusion Upadacitinib can rapidly,effectively and sustainably control the disease in patients with moderate and severe IBD,with high safety.

Objective To develop the assessment scale of proactive health behavior ability for the disabled elderly in nursing homes and to test its reliability and validity.Methods The first draft of the scale was formed by literature review,qualitative interviews and Delphi method.From December 2023 to March 2024,525 disabled elderly people from 9 nursing homes in Sichuan Province and Chongqing City were selected as the survey subjects,and item analysis and reliability and validity test were carried out on the scale.30 disabled elderly people were re-investigated after 2 weeks to calculate the retest reliability of the scale.Results The scale consisted of 4 dimensions and 27 items.Exploratory factor analysis extracted 4 common factors,with the cumulative vanance contribution rate of 65.992％,and confirmatory factor analysis showed that the modified model fitting index was within acceptable range.The content validity index at item level was 0.917-1.000,and that at scale level was 0.997.The Cronbach's α coefficient,test-retest reliability and split-half reliability of the total scale were 0.944,0.997 and 0.882,respectively.Conclusion The scale has good reliability and validity,and it can be used to evaluate the proactive health behavior ability of the disabled elderly in nursing homes.

Objective:To explore the locations of the lumbosacral nerve roots by use of the magnetic stimulation.Methods:Thirty healthy subjects were studied. The projections of the right L 2 to S 1 intervertebral foramina on their body surfaces were determined manually with ultrasound assistance. Magnetic stimulation was applied to different nerve root segments to induce compound muscle action potentials (CMAP) in the vastus medialis, tibialis anterior, and gastrocnemius muscles of the lower limbs. The changes in latency, amplitude, and motor threshold were observed. Results:Magnetic stimulation on the L 2-L 3 segment resulted in a significant direct excitation of the vastus medialis. That on the L 5-S 1 segment evoked a significant direct excitatory effect on the tibialis anterior and gastrocnemius, with a motor threshold below 40%, an amplitude exceeding 1mV, and many effective responses. However, during the magnetic stimulation on the L 4 segment, the amplitude of the vastus medialis was above 1mV, with no significant differences in the number of effective responses among the muscle groups. Moreover, there was a stepwise change in the latency of effective muscle responses to magnetic stimulation at different segments. The CMAP latencies of 12+ ms for the tibialis anterior and 13+ ms for the gastrocnemius indicated activation of the L 5 and L 4 nerve roots, respectively, while those of 6+ ms, 7+ ms, and 8+ ms for the vastus medialis suggested activation of the L 4, L 3, and L 2 nerve roots, respectively. Conclusions:Based on the responses (CMAP latency, amplitude and motor threshold) of the vastus medialis, tibialis anterior and gastrocnemius to magnetic stimulation at different L 2 to S 1 segments, the spinal nerve root segments responsible for innervation can be inferred.

ObjectiveTo re-evaluate the systematic reviews/Meta-analyses （SRs/MAs） of tonic traditional Chinese medicine （TCM） injections against cerebral ischemic stroke （CIS） and provide evidence support for clinical practice and decision-making. MethodTCM injections of different varieties were obtained after searching the three major drug catalogues. Seven Chinese and English databases were searched from database inception to March 13，2022，for the relevant SRs/MAs. The methodological quality，risk of bias，reporting quality，and quality of evidence were assessed by Assessment of Multiple Systematic Reviews-2 （AMSTAR-2），the Risk of Bias in Systematic Review （ROBIS），the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 （PRISMA 2020），and the Grading of Recommendations Assessment，Development，and Evaluation （GRADE）. In addition，the literature overlap matrix was established to calculate the corrected covered area （CCA） and evaluate the rate of overlaps of the original literature. ResultFive types of TCM injections and 18 SRs/MAs were included. AMSTAR 2 evaluation showed that the methodological quality of 18 SRs/MAs was extremely low，and 14 SRs/MAs had a high risk of bias assessed by ROBIS. The quality evaluation results reported by the PRISMA 2020 showed that the scores of the studies included ranged from 19.5 to 28.5，with 10 being of medium quality and eight of low quality. The evaluation with the GRADE system demonstrated that one outcome was moderate-quality evidence，15 outcomes were low-quality evidence，and 41 outcomes were very low-quality evidence. The CCA of the included SRs/MAs was 0.263，indicating a low rate of overlaps of the original literature. ConclusionTonic TCM injections are effective and safe in the treatment of CIS，but this conclusion should be treated with caution because of the low quality of methodology，reports，and evidence in published SRs/MAs. It is recommended to improve the study design，obtain clinical evidence of higher quality，and conduct systematic evaluations in strict accordance with procedures to standardize the reporting of research results.

OBJECTIVE: To explore the clinical manifestations and genetic characteristics of patients with congenital central hypothyroidism due to variants of IGSF1 gene. METHODS: Clinical data, results of genetic testing, and follow-up of four patients admitted to Children's Hospital of Soochow University during 2017 to 2021 were retrospectively analyzed. RESULTS: All of the four patients were males. Patient 1 had presented neonatal jaundice, patients 2 and 3 were admitted for growth retardation during childhood, and thyroid function test indicated slightly low free thyroxine (FT4), patient 4 was found to have reduced FT4 in the neonatal period. Genetic testing revealed that all of the four patients have harbored pathogenic variants of the IGSF1 gene, which were all inherited from their mothers. The thyroid functions in all patients were well controlled with oral levothyroxine and regular follow-up. CONCLUSION Pathogenic variants of the IGSF1 gene probably underlay the congenital central hypothyroidism with a variety of clinical manifestations, and genetic testing can facilitate the diagnosis at an early stage.

To analyze the clinical features and genetic variants of a child with type 4 familial partial lipodystrophy (FPLD4) and the initial manifestation of diabetes.The male patient with the age of 13 years and 5 months, and the diabetes course was about 3 years, the patient was admitted to Children′s Hospital of Soochow University on November 10, 2021(4 th hospitalization at the hospital), in the course of diabetes, the children repeatedly suffered from diabetes ketoacidosis, and lipid metabolism complications gradually emerged.The gene sequencing showed that the proband and his mother carried dual gene mutations of PLIN1 c. 1325delG(p.G442Afs*99) and SPINK1 c. 194+ 2T>C(p.? ). The PLIN1 gene was the causal gene of FPLD4.The mutations of c. 1325delG in the PLIN1 gene had not been previously reported.Based on the clinical phenotype, family history and genetic testing findings, the patient was diagnosed as FPLD4.In addition, the mutation of SPINK1 c. 194+ 2T>C(p.? ) might increase the risk of chronic pancreatitis.This case report enriched the clinical characteristics and genotype data of FPLD4.Gene sequencing assisted the accurate diagnosis of the type of diabetes.The effects of dual gene mutations on disease progression should be concerned, which were of great significance to develop treatment regimen and disease management.

Sepsis-related deaths account for more than 50% of the total deaths in the world and are the primary problem threatening public health. Timely and rapid diagnosis is the key to improving the survival rate of patients with sepsis. Blood culture is a commonly used method to diagnose sepsis in clinics. However, it is time-consuming and unstable, which cannot used for pathogen quickly identification. In recent years, Microbiological rapid on-site evaluation (M-ROSE) based on morphological technique is applying to the clinics, showing significant advantages in timeliness and convenience, which would overcome the shortcomings of traditional diagnostic methods and be conducive to diagnosis of sepsis.

ObjectiveTo investigate the effect of Zishen Huoxue prescription on promoting neurogenesis in hippocampal CA1 region of vascular dementia （VD） rats by regulating mitophagy. MethodThe 2-VO method was used to establish the VD rat model and 60 SD rats were randomly divided into sham operation group， model group， donepezil hydrochloride group， and Zishen Huoxue prescription low-dose（8.9 g·kg^-1）， medium-dose（17.8 g·kg^-1） and high-dose（35.6 g·kg^-1） groups. Morris water maze test was performed to detect the escape latency and the number of crossing platform in each group. The expression of phosphatase and tensin homology-induced kinase 1 （PINK1） and Parkinson protein （Parkin） mRNA in hippocampal CA1 region was detected by Real-time fluorescent quantitative polymerase chain reaction（Real-time PCR）. Western blot was used to determine the expression of mitochondrial autophagy signaling pathway-related proteins Parkin， prohibitin 2 （PHB2）， mitofusin 2 （Mfn2） and dynamin-related protein 1 （Drp1） in hippocampal CA1 region. The neurogenesis in hippocampal CA1 region was tested by Brdu method. ResultCompared with the conditions in the sham operation group， the learning and spatial memory abilities of the model group were decreased （P<0.05）， with damaged mitochondrial structure and autolysosome formation in the hippocampal CA1 region. The expressions of Parkin， Pink1 mRNA and Parkin， PHB2， and Drp1 proteins were up-regulated （P<0.05）， while the expression of Mfn2 protein and the neuronal regeneration in hippocampal CA1 region were reduced （P<0.05， P<0.05）. Compared with the conditions in the model group， Zishen Huoxue prescription enhanced the learning and spatial memory abilities of VD rats （P<0.05）， increased the number of autophagosomes in hippocampal CA1 region and improved the mitochondrial structure. The expression of Parkin， Pink1 mRNA and Parkin， PHB2， and Drp1 proteins in hippocampal CA1 region was up-regulated （P<0.05， P<0.01）while the expression of Mfn2 protein was down-regulated（P<0.05， P<0.01）. The number of new neurons in hippocampal CA1 region was also increased（P<0.05， P<0.01）. ConclusionThe promoting effect of Zishen Huoxue prescription on the neurogenesis in hippocampal CA1 region of VD rats was related to the mitophagy mediated by Pink1/Parkin signaling pathway.
