Introduction: Psoriasis vulgaris is a chronic, immune-mediated inflammatory dermatosis characterized by erythematous, scaly plaques that substantially impair physical, psychological, and social well-being. Although modern therapies—topicals, phototherapy, systemic agents, and biologics—have improved disease control, many patients experience incomplete remission, adverse effects, or limited accessibility. Traditional Mongolian soaking therapy, particularly the “Five medicinal Springs” decoction, has historically been used to alleviate psoriasis-like conditions; however, contemporary evidence generated through rigorous clinical study remains limited. This randomized controlled trial aimed to evaluate its efficacy and safety. Methods: A total of 60 adults with psoriasis vulgaris were enrolled between October 2019 and February 2022 at the Affiliated Hospital of Inner Mongolia University for Nationalities. Participants were randomized equally into an intervention group (n=30) and a placebo group (n=30). The intervention group received daily decoction baths prepared from ledum palustre. L, Juniferus dahurica Pall, Myricaria longifolia Willd. Ehrenb, Ephedra monosperma S.G.Gmel ex C.A.Mey, and Artemisia frigida Willd, combined with composite glycyrrhizic acid and a hyaluronic biological membrane. The placebo group received warm-water baths with identical adjunct therapy. Treatment spanned 4 consecutive weeks. Clinical outcomes included PASI and its sub scores (erythema, scaling, infiltration), lesion area, pruritus score, Dermatology Life Quality Index (DLQI), and dermatoscopic grading. Statistical analysis employed Mann–Whitney U, Wilcoxon signed-rank, and χ² tests, with significance set at p<0.05.
Baseline characteristics were comparable between groups. After 4 weeks, the intervention group demonstrated significantly greater improvement in erythema (3.23→1.50), scaling (2.90→1.37), and infiltration (2.57→0.77) (all p<0.001). Overall clinical efficacy was higher in the intervention arm (76% vs 53%; p=0.031). DLQI, pruritus scores, and dermatoscopic findings also improved more prominently in the intervention group. No serious adverse events or abnormal laboratory findings were observed. Conclusion Four weeks of “Five medicinal Springs” decoction bathing produced meaningful clinical improvement in psoriasis severity, symptoms, and quality of life, with an excellent safety profile. Further multicenter, long-term randomized trials are warranted to validate these findings and elucidate underlying mechanisms.

Objective:To compare the impacts of external fixation of different durations on rehabilitation outcomes after open repair of acute Achilles tendon rupture.Methods:A prospective cohort study was conducted to analyze the clinical data of patients with unilateral acute closed Achilles tendon rupture admitted to Peking University Third Hospital from August 2020 to August 2023. Patients were divided into Group A ( n=96), Group B ( n=347), Group C ( n=346), and Group D ( n=105) based on different postoperative immobilization durations (0, 2, 4 and 6 weeks, respectively). After all the patients received identical open repair procedure, Group A was rehabilitated immediately but the other groups were rehabilitated with the same protocol after removal of the external fixation. Four groups were compared in terms of recovery time of one-leg heel-rise height (OHRH), recovery time of light exercise (LE) in brisk walking and jogging and recovery time of range of motion (ROM). Visual analogue scale (VAS) scores were also compared at 2, 4, 6 and 8 weeks postoperatively. Achilles tendon total rupture score (ATRS) and American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores were evaluated at 6, 8, 10, 12, 14 and 16 weeks postoperatively.

Superficial wound infection occurred in 12 patients [5.2%(5/96) in Group A, 0.6%(2/347) in Group B, 0.6%(2/346) in Group C and 2.9%(3/105) in Group D] ( P<0.01) while rerupture occurred in 16 [9.4%(9/96) in Group A, 1.2% (4/347) in Group B, 0.9%(3/105) in Group C, and 0 patient in Group D] ( P<0.01). Conclusion:For patients with unilateral acute Achilles tendon rupture, two weeks of postoperative external fixation after open repair can shorten the time of returning sports, alleviate pain, and promote functional recovery, without increasing the risk of complications.

Exertional heatstroke is defined as a serious clinical syndrome typically characterized by impaired thermoregulation in high-temperature and high-humidity environments, resulting in heat production exceeding heat dissipation, causing core body temperature to exceed 40 centigrade, accompanied by central nervous system dysfunction and multi-organ failure. At present, the commonly used exertional heatstroke animal model is to put mice on a treadmill to run under high temperature and humidity conditions, but additional electrical stimulation is required to maintain the continuous running state of mice. However, additional electrical stimulation may lead to a further increase in mouse body temperature, which adversely affects the stability of the model. Therefore, medical staff from the intensive care unit of Xijing Hospital, Air Force Medical University, specially designed an intelligent experimental device for the exertional heatstroke model in mice, and obtained the national invention Patent of China (ZL 2022 1 1101721.2). The device integrates climate chamber, LCD touch screen and multiple sets of forced running wheel. Experimenters can observe and control the temperature, humidity, and wheel rotation parameters in the climate chamber in real time through a LCD touch screen. Each set of forced running wheel is equipped with a driving device that can be independently controlled. The device makes the mice run continuously without additional stimulation and enables the experimental personnel to observe and control the conditions in the climate chamber. The device successfully solves the problem of instability of the exertional heatstroke animal model and is convenient for the experimental personnel to control flexibly.

ObjectiveTo investigate the differences in clinical features and mortality rate between native patients with chronic liver failure （CHF） and migrated patients with CHF after treatment with double plasma molecular adsorption system （DPMAS） in high-altitude areas. MethodsA total of 63 patients with CHF who received DPMAS treatment in the intensive care unit of General Hospital of Tibet Military Command from January 2016 to December 2021 were enrolled， and according to their history of residence in high-altitude areas， they were divided into native group with 29 patients and migrated group with 34 patients. The two groups were compared in terms of baseline data and clinical features before and after DPMAS treatment. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the paired t-test was used for comparison before and after treatment within each group； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups， and the Wilcoxon signed rank sum test was used for comparison before and after treatment within each group； the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison of the risk of death. ResultsCompared with the native group， the migrated group had a significantly higher proportion of Chinese Han patients （χ²=41.729， P<0.001）， and compared with the migrated group， the native group had a significantly longer duration of the most recent continuous residence in high-altitude areas （Z=3.364， P<0.001）. Compared with the native group， the migrated group had significantly higher MELD score and incidence rates of hepatic encephalopathy， hepatorenal syndrome， and gastrointestinal bleeding （Z=2.318， χ²=6.903， 5.154， and 6.262， all P<0.05）. Both groups had significant changes in platelet count （PLT）， hemoglobin count （HGB）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， albumin， total bilirubin （TBil）， direct bilirubin （DBil）， lactate dehydrogenase （LDH）， creatinine （Cr）， and international normalized ratio （INR） after DPMAS treatment （all P<0.05）. Before DPMAS treatment， compared with the native group， the migrated group had significantly higher levels of ALT， AST， TBil， DBil， LDH， Cr， BUN， and INR （all P<0.05） and a significantly lower level of HGB （P<0.05）； after DPMAS treatment， compared with the native group， the migrated group had significantly greater reductions in PLT and HGB （both P<0.05） and still significantly higher levels of ALT， AST， TBil， DBil， LDH， BUN， and INR （all P<0.05）. The 60-day mortality rate of patients after DPMAS treatment was 52.5% （95% confidence interval ［CI］： 41.7 — 63.8） in the native group and 81.3% （95%CI： 77.9 — 85.6） in the migrated group. Compared with the native group （hazard ratio ［HR］=0.47， 95%CI： 0.23 — 0.95）， the migrated group had a significant increase in the risk of death on day 60 （HR=2.14， 95%CI： 1.06 — 4.32， P=0.039）. ConclusionCompared with the native patients with CHF in high-altitude areas， migrated patients have a higher degree of liver impairment， a lower degree of improvement in liver function after DPMAS treatment， and a higher mortality rate. Clinical medical staff need to pay more attention to migrated patients with CHF， so as to improve their survival rates.

With the increasing average life expectancy and the growing global aging population, cognitive frailty in the elderly has emerged as a new concept and a key focus of research in geriatrics.Cognitive frailty shows potential for reversibility, and early screening and intervention can have a positive impact on either recovering or slowing down cognitive decline in older adults, making it a promising target for promoting healthy aging.However, research on cognitive frailty is still in its nascent stages, and there is no consensus on its definition and screening criteria.This review provides an overview of the current research progress on the definition, epidemiological status, assessment tools, influencing factors, and intervention strategies for cognitive frailty.The aim is to enhance healthcare professionals' understanding of cognitive frailty in the elderly and improve diagnostic, treatment, and prevention approaches.

ObjectiveTo study the inhibitory effect of polyphyllin Ⅰ （PPI） on the growth of colorectal cancer cells and its molecular mechanism. MethodRKO cells were cultured and divided into a blank group and PPI treatment groups with concentrations of 0.6， 0.8， 1.0 μmol·L^-1， respectively. HRT18 cells were cultured and divided into a blank group and PPI treatment groups with concentrations of 1.2， 1.4， 1.6 μmol·L^-1， respectively. The effects of PPI on the proliferation and morphology of colorectal cancer were detected by cell proliferation toxicity assay， trypan blue exclusion assay， plate clone formation assay， and confocal high-intension cell imaging analysis system. Flow cytometry was used to detect the apoptosis rate of colorectal cancer cells. The pQCXIP-GFP-LC3 plasmid transfection assay was used to detect the formation of autophagosomes in colorectal cancer cells after PPI treatment. Western blot was used to detect the expression of apoptosis-related proteins Caspase-3， Caspase-8， and poly ADP ribose polymerase （PARP）， the expression of autophagy related protein LC3Ⅱ， and the expression and phosphorylation of Hippo signaling pathway proteins LATS1 and YAP. In the plvx-Flag-YAP plasmid transfection assay， YAP was overexpressed and treated with PPI， and the proliferation of colorectal cancer cells was detected by cytotoxicity assay. The expression of LC3Ⅱ and PARP in colorectal cancer cells was detected by Western blot. SwissADME predicted pharmacokinetic parameters of PPI. ResultAs compared with the blank group， the survival rate and clone formation ability of colorectal cancer cells in the PPI group were significantly decreased （P<0.01）， the cell area of colorectal cancer cells in the PPI group was significantly decreased， and the roundness of colorectal cancer cells was significantly increased （P<0.01）. As compared with the blank group， the apoptosis rate of colorectal cancer cells in PPI treatment groupw was significantly increased （P<0.01）， the expression of apoptotic proteins Caspase-3 and Caspase-8 protein precursor in PPI treatment groups was decreased， and the cleavage of PARP was increased （P<0.01）. As compared with the blank group， the expression level of autophagy-related protein LC3Ⅱ in colorectal cancer cells in PPI treatment groups was significantly increased， and the formation of autophagosomes was promoted （P<0.01）. As compared with the blank group， the expression of YAP protein in colorectal cancer cells in PPI treatment groups was significantly decreased， and the expressions of phosphorylated LATS1 and YAP were significantly increased （P<0.01）. As compared with the blank group， overexpression of YAP could significantly antagonize the effect of PPI on apoptosis， autophagy activation， and proliferation inhibition of colorectal cancer cells. SwissADME simulation results showed that PPI had good drug like activity. ConclusionPPI can induce apoptosis and autophagy of colorectal cancer cells through targeted activation of Hippo signaling pathway， thereby inhibiting their proliferation.

Objective:To explore the change trend of average hospitalization expense and cost structure of inpatients after the implementation of diagnosis-intervention packet (DIP) payment reform in Zhuhai.Methods:The data of hospitalization expense and the proportion of each classification cost (i.e. the value of a classification cost per thousand yuan of medical cost) in Zhuhai before and after the reform were analyzed by interrupted time series method, and the changes of per capita hospitalization cost and cost structure were studied.Results:The average hospitalization expense showed a linear change trend before and after the reform, and the immediate level and the slope of regression line did not change significantly after the reform, which was basically consistent with the trend before the reform. After the implementation of DIP, the proportion of various categories of expenses changed. Among them, the proportion of comprehensive medical services, treatment, traditional Chinese medicine, western medicine, blood and blood products, and other categories changed significantly, P values were less than 0.05. There was no obvious change in the proportion of expenses of diagnosis, rehabilitation and traditional Chinese medicine, but there was a change in the immediate level. The change in the level of diagnosis was -13.649 ( P< 0.001), the change in the level of rehabilitation was -1.053 ( P< 0.001), and the change in the level of traditional Chinese medicine was 2.781 ( P< 0.001). The immediate level and trend change of the proportion of consumables after the reform was not obvious. Conclusions:After the implementation of DIP payment in Zhuhai, the average expense of inpatients has not changed significantly, but the expense structure has changed significantly.

【Objective】 To investigate the molecular mechanism of long non-coding RNA (lncRNA) TDRG1 in facilitating the malignant progression and poor prognosis of patients with cervical cancer. 【Methods】 Cervical cancer cell lines and normal cervical cell Ect1/E6E7 were collected. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of TDRG1. Cervical cancer cell lines were transfected with TDRG1-siRNA, and the proliferation of cancer cells was detected by CCK-8 method and cell plate cloning experiment. The invasion and migration of cancer cells were measured by Transwell experiment. The apoptosis of cancer cells was examined by flow cytometry, and the expressions of relevant proteins were tested by Western blot. 【Results】 Compared with Ect1/E6E7, cervical cancer cell lines showed relatively increased expression of TDRG1. Downregulation of TDRG1 expression inhibited the proliferation and colony formation (162±21 vs. 411±33, P<0.05), as well as the invasion and migration (invasion: 86±13 vs. 315±38, P<0.01; migration: 177±22 vs. 406±41, P<0.01) of Hela cells. Meanwhile, the apoptosis of Hela cells increased [(28±1.5)% vs. (16±1.2)%, P<0.05] and the expression of Bcl-2 protein reduced. In addition, TDRG1 knockdown also decreased the activity of autophagy in Hela cells. 【Conclusion】 TDRG1 facilitates the malignant biological progression of cervical cancer by inhibiting the apoptosis and providing a protective autophagy in cervical cells.
