Objective:To explore the efficacy of percutaneous vertebroplasty (PVP) using the partition injection technique in the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ.Methods:A retrospective study was conducted of the 30 patients with stage Ⅰ or Ⅱ Kümmell’s disease (the partition group) who had been treated by PVP using the partition injection technique at Department of Spinal Surgery, Zhengzhou Orthopedic Hospital from January 2020 to January 2022. The data of another 30 patients who had been treated at the same department and the same period using conventional PVP for stage Ⅰ or Ⅱ Kümmell's disease were selected as the conventional group. In the partition group, there were 13 males and 17 females, with an age of (72.3±10.1) years and disease duration of (3.1±1.5) months. Seventeen thoracic and 13 lumbar vertebrae were affected. In the conventional group, there were 11 males and 19 females, with an age of (75.5±12.7) years and disease duration of (3.5±1.8) months. Eighteen thoracic and 12 lumbar vertebrae were affected. Surgical time, volume of bone cement injected, bone cement leakage, and bone cement distribution were compared between the 2 groups. The heights of the anterior and middle vertebral bodies, kyphotic Cobb angle, visual analog scale (VAS) pain score, and Oswestry disability index (ODI) were assessed postoperatively at 1 day, 6 months, and the last follow-up and compared between the 2 groups.Results:No significant differences were found in the baseline data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (17.3±3.1) months. There were no significant differences in the surgical time or bone cement leakage between the 2 groups ( P>0.05). The volume of bone cement injected in the partition group was significantly higher [(6.3±1.5) mL] than that in the conventional group [(4.9±1.0) mL] ( P<0.05). Bone cement distribution was significantly better in the partition group than that in the conventional group ( P<0.05). At postoperative 1 day, 6 months, and the last follow-up, the partition group was significantly better than the conventional group in anterior vertebral body height, middle vertebral body height, and kyphotic Cobb angle ( P<0.05). At the 6-month and the last follow-ups, the partition group was also significantly better than the conventional group in VAS pain score and ODI ( P<0.05). Conclusion:In the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ, compared with conventional PVP, PVP using the partition injection technique may lead to better long-term outcomes due to its better bone cement distribution, more adequate cement injection, and better restoration of vertebral body heights and correction of local deformity.

AIM:To quantitatively assess the early alterations of retinal and choroidal microcirculation and microstructure in systemic lupus erythematosus(SLE)patients without coexisting retinopathy via ultra-widefield swept-source optical coherence tomography angiography(UWF SS-OCTA).METHODS:Cross-sectional study. Totally 64 cases(64 eyes)that diagnosed as SLE without associated retinopathy at the Affiliated Hospital of Xuzhou Medical University from May to October 2024 were enrolled as the study group(Randomly assign one eye to the study group). Simultaneously, age-and gender-matched healthy individuals were recruited as the control group. All participants underwent UWF SS-OCTA. The deep capillary plexus(DCP), superficial capillary plexus(SCP), total retina, choriocapillaris(CC), as well as the choroidal medium and large vessel density(VD)in both the central and peripheral retinal areas of both groups of patients were compared. Additionally, parameters such as choroidal vascularity volume(CVV), choroidal vascularity index(CVI), thickness of the inner retina, outer retina, entire retina, and choroid in both central and peripheral area. SLE patients were categorized into three subgroups based on the SLE disease activity index(SLEDAI-2K), including 20 cases(20 eyes)in mild-and no-activity group(SLEDAI-2K≤6), 20 cases(20 eyes)in moderate-activity group(7

Trigeminal neuralgia is characterized by intense pain in the sensory distribution area of the trigeminal nerve. It can be triggered by non-noxious stimuli such as brushing teeth and washing face. At present, the treatment of trigeminal neuralgia mainly includes oral drugs and surgical treatments. A 92-year-old patient with trigeminal neuralgia was reported. The pain could not be alleviated because the patient was unable to tolerate the side effects of drugs and surgical treatment. Taking into account the onset time and the duration of the curative effect, botulinum toxin type A was combined with cobrotoxin for the treatment of the patient. As a result, the pain symptoms were rapidly alleviated and remained in a relieved state for 8 months. The clinical characteristics of this patient were summarized in this article, and the possible synergistic mechanisms of action of the 2 drugs were discussed. The ultimate objective is to furnish a broader spectrum of alternatives and references for clinical practice.

Objective:To evaluate and compare the clinical efficacy and safety of three different medicated eye patches in the treatment of Demodex blepharitis. Methods:A multicenter, randomized, double-blind, parallel-controlled clinical trial was conducted.A total of 140 patients (280 eyes) with Demodex blepharitis were recruited in Shanghai Jing'an District Shibei Hospital, Xi'an Fourth Hospital and Kunming First People's Hospital from July 2021 to December 2022.The affected eyes were randomly divided into tea tree oil group, okra oil group, basal fluid control group and metronidazole group by the random number table method.Eye patches containing 20% tea tree oil, 1% okra oil, prepared base solution and 2% metronidazole were applied to the eyes for 28 days by the double-blind method.The count of Demodex was evaluated before treatment and on days 14 and 28 of treatment.Ocular surface symptoms were scored according to Ocular Surface Disease Index (OSDI). The degree of congestion at the eyelid margin and cylindrical dandruff at the root of eyelashes were scored under a slit lamp microscope.The effective rate was calculated according to the comprehensive scores above, and the adverse reactions of the subjects were observed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shanghai Jing'an District Shibei Hospital (No.YL-20200320-05). All the subjects were informed of the significance, purpose and method of the study.Written informed consent was obtained from each subject before any medical examination. Results:All subjects completed the treatment and follow-up, and the loss to follow-up rate was 0%.After 14 and 28 days of treatment, the Demodex count was significantly decreased in all groups compared with before treatment (all at P<0.05). After 28 days of treatment, the number of Demodex in tea tree oil group, okra oil group and metronidazole group were significantly lower than that in basal fluid control group, with statistically significant differences (all at P<0.05). The OSDI score, palpebral margin congestion score and cylindrical dandruff score on 14 and 28 days after treatment in tea tree oil group, okra oil group and metronidazole group were significantly lower than before treatment, showing statistically significant differences (all at P<0.05). After 28 days of treatment, the effective rates of tea tree oil group, okra oil group and metronidazole group were 71.4%, 71.4% and 62.9%, respectively, which were significantly higher than 25.7% in basal solution control group.No serious local or systemic adverse reactions were found during the treatment and follow-up. Conclusions:Eye patches containing tea tree oil, okra oil and metronidazole have significant effects on the treatment of Demodex blepharitis, which can improve the biological environment of the palpebral margin and eliminate the inflammation related to blepharitis.

Objective To investigate the therapeutic effect of traditional Chinese medicine (TCM) on portal vein thrombosis (PVT) in patients with liver cirrhosis and its medication characteristics. Methods A retrospective analysis was performed for 89 patients with liver cirrhosis and PVT who were hospitalized and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and according to whether TCM treatment was applied in combination, they were divided into TCM group with 59 patients and control group with 30 patients. Related data were collected for the two groups, including demographic data, laboratory examination, radiological examination, gastroscopy, history of surgery, portal hypertension-related complications, medication, and follow-up data. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. An ordinal polytomous Logistic regression analysis was used for multivariate analysis. TCM Inheritance Computing Platform (V3.0) was used to perform a drug effect cluster analysis of TCM prescriptions. Results The multivariate logistic regression analysis showed that esophageal and gastric varices (odds ratio [ OR ]=3.144, 95% confidence interval [ CI ]: 1.221-8.094), PVT involving the portal vein (PV) and the superior mesenteric vein (SMV) ( OR =51.667, 95% CI : 3.536-754.859), PVT involving PV+spleen vein (SV)+SMV ( OR =13.271, 95% CI : 2.290-76.928), cavernous transformation of the portal vein ( OR =11.896, 95% CI : 1.172-120.696), and TCM intervention ( OR =0.348, 95% CI : 0.129-0.938) were influencing factors for the outcome of PVT in liver cirrhosis. Follow-up results showed that compared with the control group, the TCM group had a significantly lower progression rate (16.95% vs 56.67%, P < 0.001) and a significantly lower incidence rate of variceal rupture and bleeding (8.47% vs 33.33%, P < 0.001). Effective TCM drugs with a relatively high frequency of use included deficiency-tonifying drugs (359 times, 34.6%), blood-activating and stasis-resolving drugs (202 times, 19.5%), and diuresis-inducing and dampness-draining drugs (180 times, 17.3%); the TCM drugs with a relatively high frequency of use included Astragalus membranaceus (57 times, 8.7%), Angelica sinensis (50 times, 7.6%), and leech (48 times, 7.3%); TCM drug combinations with a relatively high frequency of use included Astragalus membranaceus+Angelica sinensis, Astragalus membranaceus+leech, Angelica sinensis+leech, and Astragalus membranaceus+Angelica sinensis+leech. Conclusion Qi-tonifying, blood-activating, and stasis-breaking drugs, such as Astragalus membranaceus, Angelica sinensis, and leech, can promote the stabilization or recanalization of PVT in liver cirrhosis and reduce the incidence rate of bleeding events due to portal hypertension.

Objective:To use metagenomic sequencing to compare the differences in intestinal microbiota species and metabolic pathways in patients with hepatitis B cirrhosis with or without ascites and further explore the correlation between the differential microbiota and clinical indicators and metabolic pathways.Methods:20 hepatitis B cirrhosis cases [10 without ascites (HBLC-WOA), 10 with ascites (HBLC-WA), and 5 healthy controls (HC)] were selected from the previously studied 16S rRNA samples. Metagenome sequencing was performed on the intestinal microbiota samples. The Kruskal-Wallis rank sum test and Spearman test were used to identify and analyse differential intestinal microbiota populations, metabolic pathways, and their correlations.Results:(1) The overall structure of the intestinal microbiota differed significantly among the three groups ( R = 0.19, P = 0.018). The HC group had the largest abundance of Firmicutes and the lowest abundance of Proteobacteria at the genus level. Firmicutes abundance was significantly decreased ( Pfdr < 0.01), while Proteobacteria abundance was significantly increased ( Pfdr < 0.01) in patients with cirrhosis accompanied by ascites; (2) LEfSe analysis revealed that 29 intestinal microbiota (18 in the HBLC-WA group and 11 in the HBLC-WOA group) played a significant role in the disease group. The unclassified Enterobacteriaceae and Klebsiella species in the HBLC-WA group and Enterobacteriaceae in the HBLC-WOA group were positively correlated with the Child-Turcotte-Pugh (CTP) score, prothrombin time, and international normalized ratio score and negatively correlated with albumin and hemoglobin levels ( P < 0.05). Escherichia and Shigella in the HBLC-WA group were positively correlated with CTP scores ( P < 0.05); (3) The correlation analysis results between the KEGG pathway and 29 specific intestinal microbiota revealed that Enterobacteriaceae and arachidonic acid, α-linolenic acid, glycerolipid metabolism, and fatty acid degradation were positively correlated in the lipid metabolism pathway, while most Enterobacteriaceae were positively correlated with branched-chain amino acid degradation and negatively correlated with aromatic amino acid biosynthesis in the amino acid metabolic pathway. Conclusion:A significant increment of Enterobacteriaceae in the intestines of HBLC-WA patients influenced hepatic reserve function and was associated with amino acid and lipid metabolic pathways. Therefore, attention should be paid to controlling the intestinal microbiota to prevent complications and improve the prognosis in patients with hepatitis B cirrhosis, especially in those with ascites.

Type 2 diabetes mellitus results from a combination of genetic and lifestyle factors, and the prevalence of T2DM is increasing worldwide. At present, there are many drawbacks in the clinical treatment of T2DM, so there is an urgent need for a new treatment method for improvement. In recent years, gene therapy has been proved to reverse T2DM related symptoms such as insulin resistance at the animal level, and no obvious side effects such as hypoglycemia have been found. Therefore, gene therapy may be the main development direction of T2DM therapy in the future. This article reviews the role of fibroblast growth factor related genes such as fibroblast growth factor 21, glucagon like peptide-1, peroxisome proliferator activated receptor and insulin in glucose and lipid metabolism and the development of T2DM, and summarized the application of various viral vectors in gene therapy of T2DM. The significance and existing problems of gene therapy in T2DM are discussed, and the possible development direction of gene therapy T2DM in the future is prospected.

Osteoarthritis (OA) is a common degenerative disease. Its most significant pathological change is destruction of articular cartilage and the main clinical symptoms are pain and dysfunction of joints. Recent studies have shown that the expression of non-coding RNA (ncRNA) in chondrocytes can abnormally up-regulate or down-regulate and alter the activities of chondrocytes like their proliferation, migration and apoptosis, thus leading to the occurrence and development of osteoarthritis. Exosomes are extracellular vesicles with a diameter of 40-100 nm, which are secreted in intercellular fluid, act as medium of intercellular communication. They protect ncRNA, protein, lipid and other bioactive materials from enzymatic degradation by encapsulating them and transferring to sibling chondrocytes, due to their good tissue permeability. They can also improve communication between cells and regulate the activities of chondrocytes. Thus, exosomes behave like gene carriers. The ncRNA carried by exosomes can supplement or adsorb the abnormal ncRNA in chondrocytes, so as to regulate the activity of chondrocytes, and is therefore considered as a possible candidate with capabilities to repair cartilages. In this study we reviewed existing literatures related to the roles and effects of exosome miRNA, lncRNA and circRNA on osteoarthritis. We also reviewed the pathogenesis of exosome ncRNA in osteoarthritis.
