Network Meta-analysis was conducted to evaluate the efficacy and safety of different traditional Chinese medicine injections combined with conventional western medicine in treatment of cerebral small vessel disease(CSVD). Computerized searches were conducted in PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, VIP, and SinoMed for randomized controlled trial(RCT) published in Chinese or English using traditional Chinese medicine injections to treat CSVD. The search time is from the inception to July 15, 2024. Literature screening and statistical analysis were conducted with NoteExpress 3.0.3, RevMan 5.3.5, and Stata 15.1.6. A total of 45 articles were included, involving 3 717 patients, with 1 944 patients in the treatment group and 1 773 patients in the control group. A total of 15 kinds of traditional Chinese medicine injections were involved. Network Meta-analysis indicated that,(1) in terms of improving clinical total effective rate, the best intervention in SUCRA was Ciwujia Injection + conventional western medicine.(2) In terms of reducing NIHSS scores, the best intervention in SUCRA was Xueshuantong Injection + conventional western medicine.(3) In terms of improving ADL scores, the best intervention in SUCRA was Danshen Injection + conventional western medicine.(4) In terms of improving MMSE scores, the best intervention in SUCRA was Xueshauntong Injection + conventional western medicine.(5) In terms of improving MoCA scores, the best intervention in SUCRA was Salvianolate Injection + conventional western medicine.(6) In terms of reducing plasma viscosity(PV), the best intervention in SUCRA was Danhong Injection + conventional western medicine.(7) In terms of reducing the hematocrit, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(8) In terms of reducing fibrinogen, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(9) In terms of reducing erythrocyte sedimentation rate(ESR), the best intervention in SUCRA was Danshen Injection + conventional western medicine.(10) In terms of reducing total cholesterol(TC), triglycerides(TG), and low-density lipoprotein(LDL), the best intervention in SUCRA was Danshen Injection + conventional western medicine. The radar chart results indicated that the advantage of Salvianolate Injection lies in improving cognitive function, while the advantage of Xueshuantong Injection lies in improving neurological function. The advantage of Xuesaitong Injection lies in improving hemodynamic parameters, and the advantage of Danshen Injection lies in improving behavioral ability, hemodynamics, and blood lipid levels. In terms of safety, there was no significant difference in the incidence of adverse reactions between the traditional Chinese medicine injection treatment group and the conventional western medicine group, and no serious adverse reactions occurred. The results showed that the combination of traditional Chinese medicine injections and conventional western medicine can effectively improve the clinical total effective rate, the neurological and cognitive functions, hemodynamic parameters, and blood lipid levels of patients suffering from CSVD. In addition, more double-blind, multi-center, large-sample RCT is needed to verify these findings and to provide more high-quality evidence on the efficacy and safety of traditional Chinese medicine injections for CSVD.

OBJECTIVE: To investigate the load distribution on the more painful and less painful limbs in patients with mild-to-moderate and severe bilateral knee osteoarthritis (KOA) and explore the compensatory mechanisms in both limbs among bilateral KOA patients with different severity levels. METHODS: A total of 113 participants were enrolled between July 2022 and September 2023. This cohort comprised 43 patients with mild-to-moderate bilateral KOA (Kellgren-Lawrence grade 2-3), 43 patients with severe bilateral KOA (Kellgren-Lawrence grade 4), and 27 healthy volunteers (healthy control group). The visual analogue scale (VAS) score for pain, the Hospital for Special Surgery (HSS) score, passive knee range of motion (ROM), and hip-knee-ankle angle (HKA) were used to assess walking pain intensity, joint function, and lower limb alignment in KOA patients, respectively. Motion trajectories of reflective markers and ground reaction force data during walking were captured using a gait analysis system. Musculoskeletal modeling was then employed to calculate biomechanical parameters, including the peak knee adduction moment (KAM), KAM impulse, peak joint contact force (JCF), and peak medial/lateral contact forces (MCF/LCF). Statistical analyses were performed to compare differences in clinical and gait parameters between bilateral limbs. Additionally, one-dimensional statistical parametric mapping was utilized to analyze temporal gait data. RESULTS: Mild-to-moderate KOA patients showed the significantly higher HSS score (67.7±7.9) than severe KOA patients (51.9±8.9; t=8.747, P<0.001). The more painful limb in all KOA patients exhibited significantly greater HKA and higher VAS scores compared to the less painful limb ( P<0.05). While bilateral knee ROM did not differ significantly in mild-to-moderate KOA patients ( P>0.05), the severe KOA patients had significantly reduced ROM in the more painful limb versus the less painful limb ( P<0.05). Healthy controls showed no significant bilateral difference in any biomechanical parameters ( P>0.05). All KOA patients demonstrated longer stance time on the less painful limb ( P<0.05). Critically, severe KOA patients exhibited significantly higher peak KAM, KAM impulse, and peak MCF in the more painful limb ( P<0.05), while mild-to-moderate KOA patients showed the opposite pattern with lower peak KAM and KAM impulse in the more painful limb ( P<0.05) and a similar trend for peak MCF. CONCLUSION Patients with mild-to-moderate KOA effectively reduce load on the more painful limb through compensatory mechanisms in the less painful limb. Conversely, severe bilateral varus deformities in advanced KOA patients nullify compensatory capacity in the less painful limb, paradoxically increasing load on the more painful limb. This dichotomy necessitates personalized management strategies tailored to disease severity.

OBJECTIVE: To compare the short-term clinical efficacy and safety of closed reduction with Kirschner wire fixation versus open reduction with plate fixation for treating osteoporotic Colles' fractures in middle-aged and elderly patients. METHODS: Between January 2018 and January 2023, 119 patients with Colles fractures were retrospectively analyzed, including 39 males and 80 females, aged from 48 to 74 years old with an average of(60.58±6.71) years old. The time from injury to operation ranged 1 to 13 days with an average of (5.29±2.52) days. According to the surgical method, they were divided into Kirschner wire fixation group (Kirschner wire group) and plate internal fixation group (plate group). In Kirschner wire group, there were a total of 68 patients, comprising 21 males and 47 females. The average age was (61.15±6.24) years old, ranged from 49 to 74 years old. Among them, 41 cases involved the left side while 27 cases involved the right side. In the plate group, there were a total of 51 patients, including 18 males and 33 females. The average age was (59.78±5.71) years old ranged from 48 to 72 years old. Among them, there were 31 cases on the left side and 20 cases on the right side. The following parameters were recorded before and after the operation:operation time, intraoperative blood loss, hospitalization days, hospitalization expenses, postoperative complications, and radiographic parameters of distal radius (distal radius height, ulnar deviation angle, palmar tilt angle). The clinical efficacy was evaluated at 3 and 12 months after the operation using Gartland-Werley and disabilites of the arm shoulder and hand (DASH) scores. RESULTS: The patients in both groups were followed up for a duration from 12 to 19 months with an average of(13.32±2.02) months. The Kirschner wire group exhibited significantly shorter operation time compared to the plate group 27.91(13.00, 42.00) min vs 67.52(29.72, 105.32) min, Z=-8.74, P=0.00. Intraoperative blood loss was also significantly lower in the Kirschner wire group than in the plate group 3.24(1.08, 5.40) ml vs 21.91(17.38, 26.44) ml, Z=-9.31, P=0.00. Furthermore, patients in the Kirschner wire group had a shorter length of hospital stay compared to those in the plate group (8.38±2.63) days vs (11.40±2.78) days, t=-3.12, P=0.00. Additionally, hospitalization cost was significantly lower in the Kirschner wire group than in the plate group 10 111.29(6 738.98, 13 483.60) yuan vs 15 871.11(11 690.40, 20 051.82) yuan, Z=-5.62, P=0.00. The incidence of complications was 2 cases in the Kirschner wire group and 1 case in the plate group, with no statistically significant difference(P>0.05). At 3 months postoprative, the radial height of the Kirschner wire group was found to be significantly smaller than that of the plate group, with measurements of (11.45±1.69) mm and (12.11±1.78) mm respectively (t=-2.06, P=0.04). However, there were no statistically significant differences observed in ulnar deviation angle and palmar tilt angle between the two groups (P>0.05). The DASH score and Gartland-Werley score in the Kirschner group were significantly higher than those in the plate group at 3 months post-operation (19.10±9.89) vs (13.47±3.51), t=4.34, P=0.00;(11.15±3.61) vs (6.41±2.75), t=8.13, P=0.00). However, there was no significant difference between the two groups at 12 months post-operation (P>0.05). CONCLUSION Compared to plate internal fixation, closed reduction with Kirschner wire support fixation yields a slightly inferior recovery of radial height;however, there is no significant disparity in the functional score of the affected limb at 12 months post-operation. Nonetheless, this technique offers advantages such as shorter operation time, reduced intraoperative blood loss, decreased hospitalization duration, and lower cost.

Improving the prognosis of patients with colorectal cancer (CRC) holds important clinical and social significance. Immunotherapy is an emerging therapy approach for cancers, which mainly include immune checkpoint inhibitors (ICI), immune vaccine and adoptive cell therapy. ICI have achieved good clinical translation in treatment of metastatic CRC with deficient DNA mismatch repair/high microsatellite instability (dMMR/MSI-H) status. The application of some ICI, such as PD-1 inhibitors pembrolizumab and nivolumab, in this type patients have been approved by the FDA. In addition,numerous positive results are acquired in clinical trials of neoadjuvant therapy for resectable dMMR/MSI-H CRC. These results greatly bolstered the exploration enthusiasm of CRC immunotherapy. However, the proficient DNA mismatch repair/microsatellite stability (pMMR/MSS) CRC, which accounting for the vast majority in related patients, hardly benefit from ICI therapy. Various combination strategies, mainly including ICI combined with traditional chemotherapy, radiotherapy, or targeted therapy, have been attempted to alter the “cold tumors” microenvironment characteristics of pMMR/MSS CRC in clinical trials, whereas no breakthrough results were reached. Theoretically, tumor vaccines are ideal choice to break down the barrier of insufficient immune infiltration in solid tumors. However, the outcomes of related clinical trials in CRC patents are not satisfactory, and partially due to the weak specificity of the applied tumor-associated antigens. Clinical studies of adoptive cell therapy in CRC are also actively underway. The favorable efficacy of tumor-infiltrating lymphocyte, cytokine-induced killer (CIK) and dendritic cell-CIK in CRC have been confirmed, while the CAR-T and TCR-T therapies need more exploration based on screening more suitable antigens and optimizing engineering design. In this review, we made a summary based on the mainline of clinical studies related to diverse immunotherapies, so as to clarify the progress of CRC immunotherapy and provide bases for exploration of better treatment options.

Acute lung injury (ALI), in which various factors inside and outside the lung lead to hypoxemic respiratory insufficiency and even the development of acute respiratory distress syndrome, has a high morbidity and mortality rate, and its pathogenesis is characterized by complex signaling pathways and limited therapeutic options. A large number of studies have reported that nuclear factor kappa B (NF-κB), phosphatidylinositol 3-kinase (PI3K)/Akt, mitogen-activated protein kinase (MAPK), AMP-activated protein kinase (AMPK), vascular endothelial growth factors (VEGF) and JAK/signal transducer and activator of transcription (STAT) signaling pathways are all related to the inflammatory response of ALI, and they are involved in regulating the inflammatory response process of ALI individually or cooperatively. Therefore, this article reviews the research progress on the pathogenesis-related signaling pathways and the drug interventions, aiming to provide a reference for early intervention in lung injury, optimizing the donor pool to increase the proportion of donation after cardiac death and providing quality donor protection conditions.

[Objective] To compare the clinical efficacy of pulsed radiofrequency (PRF) in patients with acute herpes zoster neuralgia (AHN) and postherpetic neuralgia (PHN). [Methods] A retrospective analysis was made on 287 patients with thoracic herpes zoster related pain. The patients were divided into acute herpes zoster neuralgia group (group AHN, within 3 months) and PHN group (group PHN, over 3 months) according to the onset time of herpes zoster. Pain degree (VAS), sleep quality (AIS), anxiety and depression (GAD-7 and PHQ-9) at 1 week, 1 month, 3 months, 6 months and 12 months after the procedure were analyzed and compared between the two groups. [Results] The scores of VAS, AIS, GAD-7 and PHQ-9 significantly decreased in both groups after surgery (P<0.001). The four scores decreased more in AHN group than in PHN group from 1 to 12 months after surgery (P<0.001). After 12 months of follow-up, there were fewer cases of taking oral pregabalin and opioids in the former group than in the latter group (P=0.001). [Conclusion] PRF has a good therapeutic effect on herpes zoster related pain and is better than PHN in relieving pain, improving sleep and anxiety and depression in AHN, or can prevent PHN.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective To study the efficacy and safety of ultrasound-guided pulse radiofrequency(PRF)treatment of the saphenous nerve for knee osteoarthritis(KOA).Methods A total of 289 KOA patients were followed up from March 2021 to October 2023 and divided into PRF group(group A,n=142)and conservative treatment group(group B,n=147)according to different treatment methods.Pain degree(VAS),knee function(OKS),and sleep quality(AIS)of the two groups were recorded before treatment and at 1 week,1 month,3 months and 6 months after treatment;the occurrence of complications was recorded for comparison between the two groups.Results After treatment,VAS,OKS and AIS scores in both groups decreased compared with those before treatment(P＜0.001).In addition,the scores of group A showed a gradual downward trend 6 months after surgery,while the scores of group B showed an overall upward trend 6 months after surgery.The scores of VAS and OKS were significantly lower in group A than in group B from 1 week to 6 months after surgery(P＜0.001).The AIS score of group A was much lower than that of group B from 1 month to 6 months after surgery(P＜0.001).There was no significant difference in the incidence of complications between the two groups(P=0.236).Conclusion Ultrasound-guided PRF treatment of the saphenous nerve is better than conservative treatment because it can better reduce pain and improve knee joint mobility and sleep in patients with KOA.

Objective:To systematically search and evaluate risk prediction models for ventilator-associated pneumonia (VAP) of ICU in order to provide references for developing higher-quality VAP risk prediction models.Methods:Relevant literature was retrieved from databases including China Biology Medicine disc, WanFang data, China National Knowledge Infrastructure, Embase, PubMed, CINAHL, Web of Science, and Cochrane Library. The search timeframe was from the establishment of the databases to September 30, 2023, limited to English and Chinese languages. Two researchers independently screened the literature and extracted data, and the PROBAST tool was used to evaluate the risk of bias and applicability of the included studies.Results:A total of 15 studies on VAP risk prediction models were included. The area under the receiver operating characteristic curve for the 15 models ranged from 0.722 to 0.982. The most frequently involved predictors were age, duration of mechanical ventilation, ICU length of stay, and comorbid chronic obstructive pulmonary disease. The overall adaptability was good, but the risk of bias was high. The main sources of bias included insufficient sample size, inappropriate data sources, lack of model performance evaluation, and inadequate attention to missing data.Conclusions:The risk of bias in studies on VAP risk prediction models is high, indicating that the field is still developing. Future research should focus on the effectiveness of different risk assessment methods to construct models with low bias, excellent predictive performance, and suitability for clinical practice in China.
