POEMS syndrome is a rare condition associated with plasma cell disorders， and it often involves multiple systems and has diverse clinical manifestations. This article reports two cases of POEMS syndrome with hepatosplenomegaly as the initial manifestation. During the course of the disease， the patients presented with lower limb weakness， hepatosplenomegaly， lymph node enlargement， ascites， hypothyroidism， positive M protein， and skin hyperpigmentation， and ¹⁸F-FDG PET-CT imaging revealed bone lesions mainly characterized by osteolytic changes and plasma cell tumors. There was an increase in the serum level of vascular endothelial growth factor. The patients were finally diagnosed with POEMS syndrome， and the symptoms were relieved after immunomodulatory treatment.

ObjectiveThis study employed the scoping review method to systematically retrieve and analyze the basic information and clinical research evidence of expensive Chinese patent medicines （CPMs）， aiming to provide a basis for future related research and clinical applications. MethodsEight Chinese and English databases were systematically searched for the clinical research evidence on expensive CPMs. ResultsEleven expensive CPMs （Angong Niuhuang Wan， Jufang Zhibao Wan， Suhexiang Wan， Pien Tze Huang， Niuhuang Qingxin Wan， Qinggong Shoutao Wan， Compound Realgar Natural Indigo Tablets， Xihuang Wan， Dingkun Wan， Babao Wan， and Guilingji Capsules） were selected. A total of 365 related studies were included in this review， comprising 331 clinical studies （of which 291 were randomized controlled trials）， 30 systematic reviews and Meta-analyses， 3 expert consensus， and 1 rapid health technology assessment. Among the 11 CPMs， 2（Angong Niuhuang Wan and Jufang Zhibao Wan） had a daily price over 500 yuan. The famous and precious Chinese medicinal materials involved included Moschus （frequency of 7）， Bovisc Alculus （7）， and Borneol （5）. The dosage forms included pills， capsules， oral liquid， tablets， and lozenges. The diseases treated by these CPMs mainly included malignant tumors， cerebrovascular diseases， gynecological diseases， and hepatobiliary system diseases. The sample sizes of the clinical studies were mainly concentrated within the range of 51-100 cases， and the main control form was CPM + basic Western medicine treatment vs. basic Western medicine treatment. The 331 clinical studies reported a total of 44 adverse events occurred， of which 36 were determined to be adverse reactions. ConclusionThe scarcity of raw materials leads to the high prices of expensive CPMs. The difficulty of conducting clinical research and the critical and severe cases treated lead to a lack of clinical research evidence with large sample sizes. The uneven distribution of existing studies， incomplete information on medicine package， and non-standard clinical research designs remain to be addressed in the future.

Objective: To analyze the factors associated with high level fear of negative evaluation (FNE) among junior high school students and to construct a nomogram risk prediction model, so as to provide scientific tools for psychological health intervention for junior high school students. Methods: A convenience sampling combined with cluster random sampling method was used to select 5 485 junior high school students from 4 cities (Wuhan, Huanggang, Xianning and Xiaogan) for an online questionnaire survey in March 2025. The total sample was randomly split into a training set ( n =3 839) and a validation set ( n =1 646). Univariate analysis was performed in the training set using Chi-square test and t-test. Variables with statistical significance were subsequently included in multivariate Logistic regression to identify independent predictors and to construct a nomogram based risk prediction model. The discriminative ability and clinical utility of the model were evaluated in the validation set using the area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA). Results: There were 1 649 junior high school students with low level FNE and 2 190 with high level FNE in the training set. The self control ability of junior high school students with lowlevel and high level FNE showed a statistically significant difference (23.96±3.96, 21.48±3.37, t=25.15, P < 0.01 ). Statistically significant differences in the detection rate of high level FNE were observed among junior high school students with different genders, family types, parenting styles, academic rankings, psychological flexibility, mobile phone addiction tendencies, emotional management training, exercise frequency, left behind experiences, and places of origin ( χ 2=82.01- 1 126.68 , all P <0.01). The results of Logistic regression analysis revealed that, the following factors were identified as significant factors influencing high level FNE among junior high school students:exercise frequency ( OR=0.21, 95%CI =0.17-0.26); parenting style ( OR=0.48, 95%CI =0.40-0.58); left behind experience ( OR=3.88, 95%CI =3.27-4.61); smartphone addiction proneness ( OR=2.19, 95%CI =0.89-0.93); self-control ability ( OR=0.91, 95%CI =0.89-0.93); and psychological flexibility ( OR=0.16, 95%CI =0.10-0.28) (all P <0.05). The AUC for the training and validation set were 0.88 (95% CI =0.87-0.89) and 0.87 (95% CI =0.85-0.89), respectively. The Hosmer-Lemeshow goodness of fit test yielded χ 2=8.57, 15.20 (both P >0.05). Conclusion The risk prediction model with high level FNE demonstrates good accuracy and can assist educators and parents in timely screening of junior high school students with high level FNE, thereby providing a basis for implementing targeted interventions.

The efficiency of CVB3 rescue in Vero cells and HEK293T cells to determine the optimal conditions for rescuing CVB3.Results:The number of phagolysosomes for virus rescue by Qiagen 57704, Qiagen 52904, and Tizol kit extracted RNA was 13.33±1.53, 150±15.00, and 1.67±0.58, respectively, and there was a statistically significant difference in the efficiency of the three method of extracting CVB3 RNA to rescue the viral RNA ( F=268.920, P<0.001); The number of phage spots formed by Lipofectamine3000 and Lipofectamine2000 transfected RNA was 74.50±3.00 and 22.00±5.00, respectively, and the difference was statistically significant ( P<0.01); Qiagen 52904 reagent extracted CVB3 nucleic acid more efficiently than Qiagen 57704 and Trizol reagents; the transfection efficiency of transfection reagent Lipofectamine 3000 was 3 times more than than that of Lipofectamine 2000, and the efficiency of virus rescue of CVB3 in HEK293T cell culture was higher than that of HeLa and Vero cells, and the copy numbers of the three kinds of viruses rescuing the virus were 6.09×10 7±8.00×10 5, 5.18×10 3±6.17×10 2 and 0, the difference was statistically significant ( F=17 383.644, P<0.001), and it was also found that the efficiency of virus rescue could be improved by multiple elution when extracting RNA. Conclusions:In this study, we successfully established the method of transfecting RNA to rescue CVB3, which can effectively improve the efficiency of virus rescue by choosing Qiagen 52904 nucleic acid extraction kit, increasing the number of elution, using Lipofectamine 3000 transfection reagent, and transfection of HEK293T cells.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective To investigate the mechanism of Sanguisorbae Radix(SR)in the treatment of ulcerative colitis(UC).Methods Using the GSE92415 dataset from the Gene Expression Omnibus database,we analyzed differentially expressed genes and carried out weighted gene correlation network analysis and FerrDb analysis.Core genes were identified through protein-protein interaction(PPI)network and correlation analysis.UC mouse model induced by dextran sulfate sodium(DSS)was constructed and treated with SR via intragastric administration for 9 days.Disease activity index(DAI)and colon length were recorded.Pathological changes in colon tissue were observed using the HE staining.Levels of inflammatory cytokines such as tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were detected by enzyme linked immunosorbent assay(ELISA).Lipid peroxidantion factors such as malondialdehyde(MDA)and glutathione(GSH)were detected using biochemical test kits.Protein expression levels of zonula occludens protein-1(ZO-1)tight junction protein,peroxisome proliferator-activated receptor gamma(PPARG),solute carrier family 7 member 11(SCL7A11),and glutathione peroxidase 4(GPX4)were examined by Western blot or immunofluorescence labeling.Results Nine differentially expressed genes associated with ferroptosis were screened and PPARG was identified as a key gene.Correlation analysis showed a strong correlation between PPARG and ferroptosis.Subsequently,the potential mechanism of SR in improving UC in mice was discussed according to the bioinformatics screening results.The experimental results demonstrated that SR significantly reduced the DAI,prevented colon shortening and improved intestinal mucosal barrier function in the colon.SR decreased TNF-α and IL-6 levels,MDA content and GSH levels in colon tissues.SR also enhanced the expression of PPARG,SLC7A11 and GPX4,which reversed the effect of DSS in mice with colitis.Conclusions Ferroptosis is closely related to UC.SR can inhibit ferroptosis by regulating PPARG and SCL7A11/GPX4 expression,thereby improving colon epithelial injury and dysfunction in UC mice.This provides ideas and directions for UC treatment strategies.
