Application value of ventricular intracranial pressure monitoring in the treatment of unilateral temporal lobe cerebral contusion / 中华创伤杂志

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

Research progress of SLC1A2 gene and essential tremor / 中国医师杂志

Essential tremor (ET) is a common dyskinesia disease characterized by tremor. ET is clinically heterogeneous. In addition to the motor symptoms with tremor as the main manifestation, it also includes non-motor symptoms such as neuropsychiatric symptoms (anxiety, depression), personality changes, sleep disorders, etc. Among them, anxiety and depression are the most common, and gradually worsen as the disease progresses, causing adverse effects on the quality of life of patients. Therefore, the early clinical full text of looking for ET psychiatric symptoms seems to have no content of the evaluation scale and is irrelevant. It is suggested that removing biomarkers plays an important role in the diagnosis and treatment of ET patients. Genome-Wide Association Studies (GWAS) describes the SLC1A2 gene associated with ET, and the EAAT2 or GLT1 encoded by this gene is associated with the anxiety and depression phenotypes of ET patients in non-motor symptoms. Up to now, the pathogenesis of ET patients is not clear, but many reports confirm that genetic factors play an important role in the pathogenesis of ET. Among them, SLC1A2 is expected to become a biomarker of the neuropsychiatric phenotype of the disease, providing a basis for clinical workers to take corresponding intervention measures in time. This article reviews SLC1A2 gene and essential tremor.

Research progress of olfactory dysfunction in Parkinson′s disease / 中国医师杂志

Parkinson′s disease (PD) is the second most common neurodegenerative disease in middle-aged and elderly people. In addition to motor symptoms, PD also has many non motor symptoms, such as dysosmia, constipation, cognitive impairment, etc. Among them, dysosmia is a common non motor symptom of early Parkinson′s disease. Research has confirmed that olfactory dysfunction (OD) can appear before the typical clinical symptoms of PD, which is of great significance to the diagnosis and treatment of diseases. However, at present, the pathogenesis of OD is still unclear, and the inspection methods have not been unified, and there is no complete cure. This article reviews the latest research progress of dysosmia in Parkinson′s disease.

Objective:To investigate the efficacy of probiotics, mesalazine and Kangfuxin liquid in combination on ulcerative colitis and its effects on inflammatory factors. Methods:A total of 106 patients with ulcerative colitis admitted to Zhejiang Sian International Hospital from November 2021 to May 2022 were included in this study. They were randomly assigned to receive treatment with either probiotics, mesalazine and Kangfuxin liquid in combination (combined therapy group, n = 53) or mesalazine alone (monotherapy group, n = 53) for 30 days. Clinical efficacy, inflammatory factor level and Rachmilewitz endoscopic score pre- and post-treatment as well as the incidence of adverse reactions were compared between the two groups. Results:Total response rate in the combined therapy group was significantly higher than that in the monotherapy group [98.1% (52/53) vs. 79.3% (42/53), χ2 = 9.40, P < 0.05]. After treatment, tumor necrosis factor-a, interleukin-8, and interleukin-17 levels were significantly decreased, and interleukin-10 level was significantly increased (all P < 0.05). Tumor necrosis factor-a, interleukin-8, and interleukin-17 levels as well as Rachmilewitz endoscopic score in the combined therapy group were significantly lower than those in the monotherapy group ( t = -2.22, -5.85, -14.08, -2.62, all P < 0.05). The interleukin-10 level in the combined therapy group was significantly higher than that in the monotherapy group ( t = 3.91, P < 0.05). The incidence of clinical symptoms in the combined therapy group was significantly lower than that in the monotherapy group [11.3% (6/53) vs. 54.7% (29/53), χ2 = 22.57, P < 0.001]. There was no significant difference in the incidence of adverse reactions between the two groups ( P = 0.540). Conclusion:Probiotics, mesalazine and Kangfuxin liquid in combination for the treatment of ulcerative colitis can improve clinical efficacy, decrease inflammatory factor levels, reduce clinical symptoms, and have a few adverse reactions.

Application value of CT and MRI radiomics based on machine-learning method in diagnosing pancreatic cancer / 中华胰腺病杂志

Objective:To investigate the application value of CT and MRI imageomics based on machine learning method in the diagnosis of pancreatic cancer.Methods:The clinical data of 62 patients with surgically resected and pathologically confirmed pancreatic cancer, who underwent enhanced CT scan, MRI plain or enhanced scan in Shanghai General Hospital between January 2014 and December 2021 were collected. According to the chronological order of surgery, 49 patients from January 2014 to December 2020 were enrolled in the training set and 13 patients from January 2021 to December 2021 were enrolled in the validation set. 3D-slicer 4.8.1 software was used to draw the region of interest in each layer of CT and MRI images for cancerous and paracancerous tissue segment. Image features were extracted by Python and the optimal feature set from the training set data was obtained by using Lasso regression model. The machine learning decision tree model was constructed. The receiver operating characteristic curve(ROC) curve was drawn, and the area under the curve (AUC) was calculated to evaluate the value of these three kinds of imageomics models in the diagnosis of pancreatic cancer.Results:The 1 767 CT features and 1 674 MRI features were obtained from enhanced CT scan, MRI plain scan and enhanced MRI scan, respectively. For the differential diagnosis model of cancerous tissue and paracancerous tissue, the enhanced CT scan data model obtained the optimal feature set involving 6 features, the MRI plain scan model obtained the optimal feature set involving 16 features, and the enhanced MRI scan model obtained the optimal feature set involving 15 features. The diagnostic model based on enhanced CT scan had an AUC of 0.98 in the training set and 1 in the verification group. The AUC of the MRI plain scan and enhanced MRI scan models in both the training set and the validation set was 1. The specificity and sensitivity of machine learning decision tree model based on the three kinds of imageomics models in the diagnosis of cancerous tissue and paracancerous tissue were 100%. For the differential diagnosis model of splenic artery wrapping, the enhanced CT scan model didn′t obtain the optimal features and had no diagnostic efficacy. The MRI plain scan model and enhanced MRI scan model obtained the optimal feature set involving 5 and 4 features, respectively. The AUC of the MRI plain scan model in the training set and the validation set were 0.862 and 0.750, respectively, with diagnostic sensitivity of 93.8% and 50.0%, and specificity of 78.6% and 100%, respectively. The AUC of the enhanced MRI scan model in the training set and the validation set were 0.950 and 0.861, respectively, with diagnostic sensitivity of 90.0% and 93.6%, and specificity of 100% and 78.6%, respectively.Conclusions:Based on the radiomics of CT enhanced, MRI plain scan and enhanced MRI scan, the machine learning diagnostic model has an accuracy of more than 90% in differentiating pancreatic cancer from paracancerous tissue. For the differentiation of splenic artery wrapping in pancreatic cancer, the diagnostic model based on enhanced MRI scan haS the best diagnostic efficiency.

Inflammatory myofibroblastic tumor of the bladder combined with cystitis glandularis: a case report / 中华泌尿外科杂志

This article reported a case of Inflammatory myofibroblastic tumor of the bladder combined with cystitis glandularis. The patient was admitted to the hospital after hematuria for more than 20 days and occasionally accompanied with dysuria.Preoperative imaging examination showed a space-occupying lesion on the anterior bladder wall, with a size about 7.7 cm×6.1 cm×4.4 cm, considering the possibility of bladder cancer. Laparoscopic robot-assisted partial cystectomy was performed, and the postoperative pathological diagnosis was cystitis myofibroblastic tumor combined with cystitis glandularis. Cystitis myofibroblastic tumor is a true tumor originating from the bladder parenchyma, which is a rare clinical disease, and it combined with cystitis glandularis has not been reported. Because its clinical manifestations and imaging manifestations are difficult to distinguish from bladder malignant tumors, the diagnosis mainly depends on pathology and immunohistochemistry stain.

The National Medical Center for Major Public Health Events invited experts in fields of infectious diseases, respiratory medicine, intensive care, pediatrics and fever clinic to develop this quick guideline based on the current best evidence and extensive clinical practices. This quick guideline aims to standardize the diagnosis and treatment of novel coronavirus Omicron infection, and to improve the disease management abilities of clinicians.

Comparison of mouse models of depression induced by different modeling methods / 生理学报

The present article was aimed to compare the effectiveness of different induction methods for depression models. Kunming mice were randomly divided into chronic unpredictable mild stress (CUMS) group, corticosterone (CORT) group, and CUMS+CORT (CC) group. The CUMS group received CUMS stimulation for 4 weeks, and the CORT group received subcutaneous injection of 20 mg/kg CORT into the groin every day for 3 weeks. The CC group received both CUMS stimulation and CORT administration. Each group was assigned a control group. After modeling, forced swimming test (FST), tail suspension test (TST) and sucrose preference test (SPT) were used to detect the behavioral changes of mice, and the serum levels of brain-derived neurotrophic factor (BDNF), 5-hydroxytryptamine (5-HT) and CORT were detected with ELISA kits. Attenuated total refraction (ATR) spectra of mouse serum were collected and analyzed. HE staining was used to detect morphological changes in mouse brain tissue. The results showed that the weight of model mice from the CUMS and CC groups decreased significantly. There was no significant change in immobility time of model mice from the three groups in FST and TST, while the glucose preference of model mice from the CUMS and CC groups was significantly reduced (P < 0.05). The serum 5-HT levels of model mice from the CORT and CC groups were significantly reduced, while the serum BDNF and CORT levels of model mice from the CUMS, CORT, and CC groups showed no significant changes. Compared with their respective control groups, the three groups showed no significant difference in the one-dimensional spectrum of serum ATR. The difference spectrum analysis results of the first derivative of the spectrogram showed that the CORT group had the greatest difference from its respective control group, followed by the CUMS group. The structures of hippocampus in the model mice from the three groups were all destroyed. These results suggest that both CORT and CC treatments can successfully construct a depression model, and the CORT model is more effective than the CC model. Therefore, CORT induction can be used to establish a depression model in Kunming mice.

AIM: To analyze the clinical characteristics and antibiotic sensitivity of traumatic endophthalmitis caused by Bacillus cereus and discuss the early diagnosis and treatment measures.METHODS: The data of 15 patients(15 eyes)with Bacillus cereus endophthalmitis admitted to the Eye Trauma Center of Shaanxi Provincial Eye Hospital from January 2019 to December 2021 were collected. The injury time, injury condition, preoperative visual acuity, corrected visual acuity in the last follow-up, operation method, bacterial culture and drug sensitivity test results were recorded.RESULTS: Among the 15 patients(15 eyes), 5 eyes with simple corneal perforating wound were treated with wound debridement and suture combined with intraocular antibiotic injection. And another 10 eyes with penetrating injuries combined with traumatic cataract and intraocular foreign bodies were treated with debridement, cataract extraction, removal of intraocular foreign bodies, vitrectomy combined with silicone oil tamponade and intraocular antibiotic injection. Among the 15 patients, 11 patients(73%)were treated effectively and the eyeball was preserved, and 4 patients(27%)were treated ineffectively and ocular evisceration was performed. Among the 11 patients with eyeball retention, 1(9%)had decreased vision, 1(9%)had unchanged vision, 4(36%)had improved vision by 1 level, and 5(45%)had improved vision by 2 levels, and the postoperative visual acuity was significantly improved. Correlation analysis showed that the course of disease was negatively correlated with corrected visual acuity(rs=-0.762, P=0.001). The cultures of vitreous humor and aqueous humor samples of patients were all grown in Bacillus cereus, and susceptibility tests were sensitive to vancomycin.CONCLUSIONS: Vancomycin is an effective drug for the treatment of Bacillus cereus endophthalmitis. Vitrectomy combined with silicone oil tamponade and intravitreal injection of vancomycin are effective method for the treatment of Bacillus cereus endophthalmitis.

Mechanism of Fructus Lycii against dry eye: an analysis based on network pharmacology and experimental verification / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the mechanism of fructus lycii in treating dry eye based on network pharmacology and experimental verification.METHODS: Taking “fructus lycii” as key words, the active ingredients and target of fructus lycii were searched by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Gene targets related to dry eye(DE)were searched by GeneCards and OMIM databases. The target genes of fructus lycii and DE were imported into Venn software to obtain the intersection target map of them. After that, the data were imported into the String database to obtain the PPI protein-protein interaction network diagram. Using Cytoscape3.7.2 software, the PPI protein-protein interaction network diagram was constructed for active ingredients, target sites and related diseases of fructus lycii. The Bioconductor platform and R language were used for gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis. And the key targets in the pathogenesis of DE were verified by experiments.RESULTS: Through TCMSP, 45 types of effective chemical components of fructus lycii, 174 target genes corresponding to active components and 131 common target genes with DE were screenedout. In accordance with the network topology of “drug-composition-disease-target”, 27 main effective components of fructus lycii were found in the treatment of DE. The PPI network was analyzed according to the high degree value, which is the key targets of fructus lycii for DE treatment, mainly including AKT1, VEGFA, CASP3, IL1B, JUN, PTGS2, CXCL8, etc. According to GO enrichment analysis, 166 biological functions and processes of fructus lycii for DE treatment were obtained. KEGG enrichment analysis showed that 31 signaling pathways were involved. Additionally, experimental verification displayed that the protein expressions of AKT1, interleukin-6(IL-6), tumor necrosis factor(TNF-α)and IL-17 in conjunctiva tissue of the DE model group were significantly increased.CONCLUSIONS: Through network pharmacology, this study confirmed that the treatment of DE by fructus lycii is a complex process involving multi-components, multi-targets and multi-pathways, and that the treatment of DE by fructus lycii is mainly regulated by anti-inflammatory and apoptosis-related molecules.

Effect and Mechanism of Cinobufotalin Against Gastrointestinal Malignant Tumors： A Review / 中国实验方剂学杂志

Digestive tract diseases， especially digestive tract tumors， including liver cancer， pancreatic cancer， and colorectal cancer， have high incidence in China. Digestive tract tumor is one of the top 10 cancers in terms of the number of new cases and deaths in the world， and the incidence and mortality of tumor diseases have been increasing year by year. Therefore， the prevention and treatment of tumors is particularly important. With the application and promotion of traditional Chinese medicine in the medical field and the rapid development of molecular biology and pharmacology， more and more potential active components of Chinese medicinal materials have been extracted and studied. These active components can inhibit tumor cells in a multi-target and multi-pathway manner. Cinobufotalin is an effective component extracted from the skin of Bufo bufo gargarizans. It has been prepared into a variety of agents with anti-tumor， immunomodulatory， cardiac boosting， pain-easing， anti-inflammatory， and swelling-relieving activities. In clinical practice， cinobufotalin is mainly used to assist the treatment of liver cancer， lung cancer， colorectal cancer， gastric cancer and other malignant tumors， which can reduce the adverse reactions of patients in the middle and late stages and improve the quality of life and five-year survival rate of patients. The available studies of molecular mechanism have demonstrated that cinobufotalin can play a therapeutic role by inducing cell apoptosis， regulating cell cycle， inhibiting cell proliferation and angiogenesis， modulating immune response， reversing multidrug resistance， enhancing radiochemotherapy sensitivity， inhibiting tumor inflammation， invasion， and metastasis， etc. This review focuses on the clinical application and mechanism of cinobufotalin against digestive tract tumors in recent years， aiming to provide a theoretical basis for the anti-tumor research of cinobufotalin， promote the application of cinobufotalin in tumor treatment， and facilitate the further research and development of this compound.

There were 80 family members of patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June 2021 to December 2022 being selected as subjects. All patients underwent laparoscopic radical resection of gastric cancer. Based on random number table, all subjects were allocated into the control group and the experiment group. Subjects in the control group performed routine surgical conversation and subjects in the experiment group performed surgical conversation based on mixed reality technology. Observation indicators: (1) baseline data of the subjects; (2) anxiety assessment of the subjects. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for inter-group comparison. Repeated measurement data were analyzed using the repeated ANOVA. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. Results:(1) Baseline data of the subjects. A total of 80 subjects were selected for eligibility, including 40 subjects in the control group and 40 subjects in the experi-ment group. There were 44 males and 36 females, aged (40±9)years. The gender (male, female), age, education background (primary school education, middle school education, high school education, junior college education, undergraduate education, postgraduate education) were 23, 17, (39±9)years, 1, 3, 9, 16, 9, 2 in subjects of the control group, versus 25, 15, (42±10)years, 0, 8, 6, 11, 14, 1 in subjects of the experiment group, showing no significant difference in the above indicators between the two groups ( χ2=0.20, t=?1.64, Z=?0.10, P>0.05). (2) Anxiety assessment of the subjects. The scores of self-rating Anxiety Scale (SAS) and Hospital Anxiety Scale (HADS) before surgical conversation, after surgical conversation, after surgery were 41±10 and 26±5, 49±11 and 32±3, 40±13 and 15±8 in subjects of the control group, versus 44±9 and 23±3, 66±16 and 28±6, 34±14 and 8±3 in subjects of the experiment group, showing significant differences in the above indicators between the two groups ( FSAS组间=8.83, FSAS时间=40.41, FSAS交互=12.21, FHADS组间=32.42, FHADS时间=321.28, FHADS交互=6.15, P<0.05). Conclusion:Compared with traditional surgical conversation, mixed reality technology based surgical conversation can relieve the postoperative conxiety of subjects.

OBJECTIVE To establish a method for simultaneous determination of 15 bile acids in Tongren niuhuang qingxin pills， and to determine the contents of 15 batches of samples. METHODS Using dehydrocholic acid as internal standard， the determination was performed by ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） method. The determination was performed on Hypersil GOLD C18 column with methanol-0.1% formic acid solution as the mobile phase by gradient elution at the flow rate of 0.2 mL/min. The column temperature was 40 ℃ ， and the sample size was 2 µL. Using heated electrospray ion source， parallel reaction monitoring mode scanning was performed in negative ion mode. SPSS 24.0 software was used for chemical pattern recognition analysis of content determination results. RESULTS The 15 bile acid components had a good linear relationship with peak area （all R2≥0.998 9）； their precision， repeatability and stability were all good （all RSD≤5.49%）； the average recoveries were 93.8%-105.7% （RSD was 0.5%-5.8%）. The average contents of taurocholic acid， 7-oxodeoxycholic acid， 12-dehydrocholic acid， glycocholic acid， 3-oxo-7α， 12α-hydroxy-5β-cholanoic acid， taurochenodeoxycholic acid， 3α-hydroxy- 7-oxo-5β -cholanic acid， hyocholic acid， taurodeoxycholic acid sodium salt hydrate， hyodeoxycholic acid， cholic acid， glycochenodeoxycholic acid， glycodeoxycholic acid， chenodeoxycholic acid and deoxycholic acid were 670.56， 25.97， 10.54， 280.12， 4.04， 29.81， 182.98， 813.55， 120.95， 220.31， 797.37， 18.37， 68.59， 30.13， 59.82 μg/g， respectively.

Spatial and temporal distribution characteristics of seasonal A(H3N2) influenza in China, 2014-2019 / 中华流行病学杂志

Objective: To analyze the spatial and temporal distribution characteristics of seasonal A(H3N2) influenza [influenza A(H3N2)] in China and to provide a reference for scientific prevention and control. Methods: The influenza A(H3N2) surveillance data in 2014-2019 was derived from China Influenza Surveillance Information System. A line chart described the epidemic trend analyzed and plotted. Spatial autocorrelation analysis was conducted using ArcGIS 10.7, and spatiotemporal scanning analysis was conducted using SaTScan 10.1. Results: A total of 2 603 209 influenza-like case sample specimens were detected from March 31, 2014, to March 31, 2019, and the influenza A(H3N2) positive rate was 5.96%(155 259/2 603 209). The positive rate of influenza A(H3N2) was statistically significant in the north and southern provinces in each surveillance year (all P<0.05). The high incidence seasons of influenza A (H3N2) were in winter in northern provinces and summer or winter in southern provinces. Influenza A (H3N2) clustered in 31 provinces in 2014-2015 and 2016-2017. High-high clusters were distributed in eight provinces, including Beijing, Tianjin, Hebei, Shandong, Shanxi, Henan, Shaanxi, and Ningxia Hui Autonomous Region in 2014-2015, and high-high clusters were distributed in five provinces including Shanxi, Shandong, Henan, Anhui, and Shanghai in 2016-2017. Spatiotemporal scanning analysis from 2014 to 2019 showed that Shandong and its surrounding twelve provinces clustered from November 2016 to February 2017 (RR=3.59, LLR=9 875.74, P<0.001). Conclusion: Influenza A (H3N2) has high incidence seasons with northern provinces in winter and southern provinces in summer or winter and obvious spatial and temporal clustering characteristics in China from 2014-2019.

Proposal and thoughts on establishing and improving multi-level dental insurance in China / 中华口腔医学杂志

Oral diseases are highly prevalent in China, while oral health services are generally underutilized and public health resources are wasted. Lacking oral insurance may be one of the leading causes. The basic medical insurance of China does not cover dental care in most cities, which is worthy to further discuss. To better understand the experience of dental insurance from international dental care practice, the dental coverage scope, content, co-pay ratio, and effects of oral insurance on oral health improvement from the abroad countries with typical health insurance systems were summarized by using scoping review. Then, we discussed the coverage scope for dental health of basic medical insurance and private insurance in China. We also analyzed the current issues of dental care coverage and cost-share. At last, we proposed thoughts and suggestions to establish and improve a multi-level oral health insurance system with Chinese characteristics under the basic medical insurance frame. In particular, we gave suggestions on increasing the coverage for high dental care xpenditure by ebasic medical insurance, supplying children and teenagers with preventive dental care, and encouraging private insurance companies to cover dental care expenditure.
