Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Da Chengqitang in Treatment of Sepsis： A Review / 中国实验方剂学杂志

Sepsis is a systemic inflammatory syndrome induced by infection and other factors， with the number of patients worldwide exceeding 10 million each year. The pathophysiological mechanism is of this disease complex. Sepsis is often accompanied by endotoxin translocation， gastrointestinal dysfunction， inflammatory cytokine activation， immune dysregulation， coagulation disorder， multiple organ function impairment and many other body imbalances， as well as systemic inflammation， apoptosis， oxidative stress injury and other cell damage mechanisms. This disease causes a heavy medical burden due to the difficult diagnosis and treatment and the poor prognosis. Great progress has been achieved in the diagnosis and treatment of sepsis with traditional Chinese medicine （TCM） and western medicine. The value of western medicine in the diagnosis and treatment of sepsis is limited due to antibiotic resistance， hormone abuse， and high medical costs. Sepsis is classified as a warm disease or typhoid fever in TCM. Da Chengqitang is a classical formula in the Treatise on Typhoid Fever to deal with the excess syndrome of Yang brightness Fu-organ. Modern medicine has proved that Da Chengqitang has the effect of inhibiting oxidative stress， reducing inflammation， and delaying apoptosis by improving gastrointestinal dynamics and regulating intestinal microecology. On the basis of the previous theoretical basis and the rich experience in the medication， medical practitioners have proposed a new therapeutic concept of using Da Chengqitang in combination with western drugs from a holistic view involving both bacteria and toxicity for treating both the symptoms and the root cause， which has a wide range of application. The article reviews the classical research and latest findings of Da Chengqitang in the treatment of sepsis， with a view to clarifying the mechanism and advantages of this formula in the adjuvant treatment of sepsis， exploring its potential efficacy， and providing timely， adequate， and scientific theoretical support for the promotion of this formula in the clinical practice.

Methods     The clinical data of patients aged≥70 years with coronary artery disease complicated with moderate mitral regurgitation, and undergoing OPCABG from January 2009 to January 2020 in Beijing Anzhen Hospital were retrospectively analyzed. The echocardiographic indicators of the patients were compared preoperatively, postoperatively before discharge and during the follow-up. Results     Finally 239 patients were enrolled. There were 136 males and 103 females, aged 74.1±3.2 years. Before postoperative discharge, 49 (20.5%) patients had no mitral regurgitation, 144 (60.3%) mild regurgitation, 46 (19.2%) moderate regurgitation, and 0 severe regurgitation. The area of mitral regurgitation was significantly improved (2.5±1.8 cm2 vs. 5.6±1.0 cm2, P<0.001). There were 10 (4.2%) patients of hospital death, 23 (9.6%) of low cardiac output, 3 (1.3%) of myocardial infarction, and 8 (3.3%) of nervous system injury after operation. As a result, 208 (90.8%) patients were followed up and the mean follow-up time was 3.4 years (range 1-9 years). The cumulative survival rates at postoperative 2, 4, 6, and 8 years were 95.8%, 88.0%, 78.4%, and 73.1%, respectively. Postoperative follow-up showed significant improvements compared with those before surgery in the area of mitral regurgitation, left ventricular ejection fraction, left ventricular end-diastolic and left ventricular end-systolic diameters (all P<0.05).

Effect of CDM3 on the co-culture of human induced pluripotent stem cells with matrigel-coated polycaprolactone to make cardiac patch / 中国胸心血管外科临床杂志

@#Objective    To provide experimental data and theoretical support for further studying the maturity of cardiac patches in other in vitro experiments and the safety in other in vivo animal experiments, through standard chemically defined and small molecule-based induction protocol (CDM3) for promoting the differentiation of human induced pluripotent stem cells (hiPSCs) into myocardium, and preliminarily preparing cardiac patches. Methods    After resuscitation, culture and identification of hiPSCs, they were inoculated on the matrigel-coated polycaprolactone (PCL). After 24 hours, the cell growth was observed by DAPI fluorescence under a fluorescence microscope, and the stemness of hiPSCs was identified by OCT4 fluorescence. After fixation, electron microscope scanning was performed to observe the cell morphology on the surface of the patch. On the 1st, 3rd, 5th, and 7th days of culture, the cell viability was determined by CCK-8 method, and the growth curve was drawn to observe the cell growth and proliferation. After co-cultured with matrigel-coated PCL for 24 hours, hiPSCs were divided into a control group and a CDM3 group, and continued to culture for 6 days. On the 8th day, the cell growth was observed by DAPI fluorescence under a fluorescence microscope, and hiPSCs stemness was identified by OCT4 fluorescence, and cTnT and α-actin for cardiomyocyte marker identification. Results    Immunofluorescence of hiPSCs co-cultured with matrigel-coated PCL for 24 hours showed that OCT4 emitted green fluorescence, and hiPSCs remained stemness on matrigel-coated PCL scaffolds. DAPI emitted blue fluorescence: cells grew clonally with uniform cell morphology. Scanning electron microscope showed that hiPSCs adhered and grew on matrigel-coated PCL, the cell outline was clearly visible, and the morphology was normal. The cell viability assay by CCK-8 method showed that hiPSCs proliferated and grew on PCL scaffolds coated with matrigel. After 6 days of culture in the control group and the CDM3 group, immunofluorescence showed that the hiPSCs in the control group highly expressed the stem cell stemness marker OCT4, but did not express the cardiac markers cTnT and α-actin. The CDM3 group obviously expressed the cardiac markers cTnT and α-actin, but did not express the stem cell stemness marker OCT4. Conclusion    hiPSCs can proliferate and grow on matrigel-coated PCL. Under the influence of CDM3, hiPSCs can be differentiated into cardiomyocyte-like cells, and the preliminary preparation of cardiac patch can provide a better treatment method for further clinical treatment of cardiac infarction.

Objective:To study the clinical effects of portal vein embolization (PVE) with N-butyl cyanoacrylate copolymer (NBCA) and with gelatin sponge (GS) as embolization materials in patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 90 patients with initial unresectable HCC who underwent PVE treatment at the Third Affiliated Hospital of Naval Medical University from November 2014 to April 2020 were included. There were 77 males and 13 females, aged 48 (25, 67) years old. Patients were divided into two groups according to the embolization materials selected in PVE: NBCA group ( n=60) and GS group ( n=30). Forty-eight and 18 patients finally underwent secondary hepatectomy in NBCA group (resectable NBCA group) and GS group (resectable GS group), respectively. Clinical data including future liver remnant (FLR) growth rate and secondary hepatectomy rate were analyzed. Survivals after hepatectomy was followed up by telephone, WeChat, and outpatient review. Results:The secondary hepatectomy rate in NBCA group was higher than that in GS group [80%(48/60) vs. 60%(18/30), P=0.043]. The waiting time from primary intervention to secondary hepatectomy in resectable NBCA group was 15 (7, 96) d, which was shorter than that in resectable GS group [40 (28, 118) d, P<0.001]. The FLR growth rate of resectable NBCA group was 9.03 (1.24, 29.64) ml/d, which was faster than that in resectable GS group [3.76 (0.08, 8.03) ml/d, P<0.001]. The recurrence-free survival (RFS) rates of patients in resectable NBCA group were 69.1%, 62.0% and 44.7% at 1, 2 and 3 years after surgery, and the overall survival (OS) rates were 76.4%, 69.5% and 59.6%, respectively. The RFS rates of patients in resectable GS group were 60.6%, 48.5% and 35.4% at 1, 2 and 3 years after surgery, and the OS rates were 66.7%, 60.6% and 42.4%, respectively. There were no significant differences in RFS and OS between two groups (all P>0.05). Conclusions:PVE with NBCA and GS as embolization material showed good efficacy in patients with initially unresectable HCC. The FLR growth rate and secondary hepatectomy rate of patients using NBCA were better than those of patients using GS.

Objective To evaluate the effect and mechanism of terminal fucosylation inhibitor 2-deoxy-D-galactose (2-D-gal) on ciclosporin (CsA)-induced renal epithelial-mesenchymal transition (EMT). Methods Fifteen male C57BL/6 mice aged 8-10 weeks were randomly and evenly divided into the control group (Ctrl group), CsA group and CsA+2-D-gal group (n=5). The expression levels of fucosyltransferase 1 (FUT1), EMT-associated proteins including E-cadherin, Vimentin, α-smooth muscle actin (α-SMA) in the kidney tissues of the Ctrl and CsA groups were detected by Western blot. The expression levels of terminal fucose in the kidney tissues of Ctrl and CsA groups were determined by immunofluorescence. The renal fibrosis of mice in each group was evaluated by Masson staining. The blood urea nitrogen and serum creatinine levels of mice in each group were detected. The in vitro EMT model of renal tubular epithelial cell HK2 was induced by CsA. HK2 cells were stimulated with 0, 2.5, 5.0 and 10.0 μmol/L CsA for 24 h, respectively. In addition, HK2 cells were divided into the Ctrl, 2-D-gal, CsA and CsA+2-D-gal groups. The morphology of HK2 cells after stimulation with different concentrations of CsA and in each group was observed. The expression levels of FUT1, E-cadherin, Vimentin and α-SMA in HK2 cells after stimulation with different concentrations of CsA and in each group were detected by Western blot. The expression level of terminal fucose in HK2 cells of the Ctrl and CsA groups was measured by immunofluorescence. Results Compared with the Ctrl group, the relative expression of E-cadherin protein was down-regulated, those of FUT1, Vimentin and α-SMA proteins were up-regulated (all P < 0.05), and that of terminal fucose in the mouse kidney tissues was up-regulated in the CsA group. Compared with the Ctrl group, the blood urea nitrogen and serum creatinine levels in the CsA and CsA+2-D-gal groups were up-regulated (all P < 0.05). Compared with the CsA group, the blood urea nitrogen and serum creatinine levels in the CsA+2-D-gal group were down-regulated (both P < 0.05). Compared with the Ctrl group, the collagen fiber deposition was increased and the relative expression of α-SMA protein was up-regulated in the mouse kidney tissues of CsA and CsA+2-D-gal groups (all P < 0.05). Compared with the CsA group, the collagen fiber deposition was decreased and the relative expression of α-SMA protein in the mouse kidney tissues was down-regulated in the CsA+2-D-gal group (both P < 0.05). With the increase of CsA concentration, the morphology of HK2 cells gradually became longer and thinner from original normal cobblestone shape, the relative expression levels of FUT1, Vimentin and α-SMA protein in HK2 cells were up-regulated, and that of E-cadherin protein was down-regulated in a concentration-dependent manner. Compared with the Ctrl group, the expression level of terminal fucose of HK2 cells was up-regulated in the CsA group. After CsA treatment combined with 2-D-gal intervention, the morphology of HK2 cells in the CsA+2-D-gal group was restored to resemble that of normal HK2 cells. Compared with the CsA group, the relative expression of E-cadherin protein in HK2 cells was up-regulated, whereas those of Vimentin and α-SMA proteins were down-regulated in the CsA+2-D-gal group (all P < 0.05). Conclusions CsA may induce EMT both in vivo and in vitro, and the terminal fucosylation is increased. 2-D-gal may inhibit CsA-induced EMT by suppressing the terminal fucosylation.

The function of circular RNA-encoded polypeptide or protein in the proliferation mechanism of human malignant tumors / 肿瘤研究与临床

Circular RNA (circRNA) is considered to be non-coding RNA due to the deletion of the 5' cap structure and lacks the function of encoding proteins or polypeptides. With the development of high-throughput transcriptome sequencing, ribosome sequencing and other technologies, researchers have discovered that there were short open reading frames (sORF) and internal ribosome entry sites (IRES) in the sequence of some circRNAs which can encode polypeptides or protein and play important roles in the proliferation of malignant tumors such as glioma, hepatoma, gastric cancer, breast cancer, and colon cancer. This paper reviews the coding function of circRNA and analyzes the role of its encoded production-polypeptides or protein in the proliferation mechanism of human malignant tumors.

ObjectiveTo explore the relationship between mental health and sleep quality of high-level shooting athletes and its significance to psychological rehabilitation. MethodsIn March, 2021, 21 high-level shooting athletes were investigated using Pittsburgh Sleep Quality Index (PSQI) and Profile of Mood State (POMS). They were divided into normal sleep group (n = 9) and sleep disorder group (n = 12). The psychological state of athletes with different sleep quality was calculated and the correlation was analyzed. ResultsThe scores of tension, anger, fatigue, and total of motional disturb (TMD) in POMS were higher in the sleep disorder group than in the normal sleep group (t > 2.18, P <0.05). The total of PSQI postively correlated with tension, anger, fatigue, depression, panic, and TMD of POMS (r > 0.454, P < 0.05). After step regression, fatigue was the main variable related to PSQI (P = 0.001). ConclusionThe sleep quality of high-level shooting athletes is affected by mental state, and the mental fatigue is the most important factor. The follow-up psychological rehabilitation professionals should pay more attention to the negative emotions and psychological fatigue of shooting event athletes.

Organ transplantation and parasitic infection / 器官移植

Parasitic infection is manifested with the characteristics of both endemic and infectious diseases, and the onset of parasitic infection is regional and infectious. The incidence of parasitic infection after organ transplantation is relatively low, primarily occurring in single case or case series in developing countries and regions. With the development of social economy and a gradual increasing number of organ transplantation, the risk of parasitic exposure is increased when the recipients travel among different countries or regions. In addition, immunosuppression is the risk factor of parasitic infection. Consequently, the risk of parasitic infection in organ transplant recipients cannot be ignored. In this article, epidemiological characteristics, clinical manifestations, diagnosis, treatment and prevention of parasitic infection after organ transplantation were classified and summarized according to literature review, aiming to provide reference for the prevention and treatment of parasitic infection in organ transplant recipients.

Risk factors of early death and long-term outcomes in myocardial infarction complicated with ventricular septal rupture / 中华老年医学杂志

Objective:To analysis the risk factors of early death and long-term outcomes of myocardial infarction complicated with ventricular septal rupture.Methods:A total of 135 patients with myocardial infarction complicated with ventricular septal rupture in Beijing Anzhen Hospital from January 2008 to December 2020 were retrospectively analyzed.According to the survival or death within 30 days after ventricular septal rupture, the patients were divided into the early survival group(n=71)and the early death group(n=64). The clinical characteristics of the two groups were observed, and the risk factors for early death group were analyzed.The long-term outcomes of the surgery group(n=69)and the non-surgery group(n=66)was analyzed.Results:The early mortality rate of patients with myocardial infarction complicated with ventricular septal rupture was 47.4%(64/135). Univariate analysis showed that age, sex, white blood cell count, platelet count, C-reactive protein level, left ventricular end-diastolic diameter, abnormal liver function, pulmonary infection, no surgery repair and Killip grade ≥3 were associated with early death as compared with the early survival group(all P<0.05). Multivariate regression analysis showed that no surgery repair( OR=16.103, 95% CI: 4.400-58.930, P<0.001)and Killip≥3 grade( OR=9.014, 95% CI: 2.506-32.428, P=0.001)and abnormal liver function( OR=5.171, 95% CI: 1.388-19.264, P=0.014)were independent risk factors for early death in patients with myocardial infarction complicated with ventricular septal rupture.During follow-up of 1.0 to 11.8(median 3.2)years, the 2-year and 10-year cumulative survival rates were significantly higher in the surgery group than in the non-surgery group(76.7% vs.16.7%, P<0.001; 73.1% vs.16.7%, P<0.001). Conclusions:No surgical repair, Killip grade ≥3 and abnormal liver function are independent risk factors for early death in patients with myocardial infarction complicated with ventricular septal rupture.The long-term outcomes of surgical treatment for myocardial infarction complicated with ventricular septal rupture is good.

Classification of lower leg osteofacial compartment syndrome / 中华创伤杂志

Osteofacial compartment syndrome (OCS) is one of the serious complications in traumatic orthopedics. If not treated in time, OCS may result in irreversible damage to nerve and muscle,even amputation or death in serious condition. 5P presents to be the classic clinical diagnosis of OCS, but it is highly subjective and cannot timely and accurately judge the progression of the disease. Intracompartment pressure manometry is the main auxiliary method for the diagnosis of OCS. Although there are many manometry methods, there is still no authoritative pressure threshold as the diagnosis standard. Clinicians often aggressively perform fasciotomy to avoid serious complications, leading to unnecessary fasciotomy. The authors retrospectively reviewed the data of patients with OCS treated at Air Force Hospital of Eastern Theater of PLA from March 2010 to March 2020 and found that some patients with OCS had gradual alleviation of clinical symptoms after appropriate conservative treatments such as brace releasing, limb stabilization and swelling subsidence, with no need of fasciotomy. However, the symptoms of some patients progressively aggravated after the above-mentioned traditional treatments and timely fasciotomy was required. The authors graded the severity of OCS and proposed for the first time the OCS grading criteria according to quantitative clinical results and quantitative indicators such as ratio of mean blood flow velocity of bilateral arteries and pulse wave changes, aiming to take corresponding intervention measures for patients with different OCS classifications, carry out more precise treatment and avoid unnecessary fasciotomy.

Based on plasma metabonomics and network analysis to research the mechanisms of Chaigui granules for treating depression / 药学学报

The purpose of this study was to systematically analyze the antidepressant mechanism of Chaigui granules from the perspective of biological metabolic network by using integrated metabolomics and biological network analysis tools. The model of chronic unpredictable mild stress (CUMS) depression rat was established, and LC-MS-based plasma metabolomics was used to identify the key metabolites and analyze metabolic pathways underlying the antidepressant effects of Chaigui Granules. The key metabolites regulated by Chaigui granules was integrated with biological network analysis tools to further focus on the key metabolic pathways and explore the potential targets of the antidepressant effect of Chaigui granules. The results showed that there were significant differences in the plasma levels of 20 metabolites in the model group compared with the control group (P < 0.05), Chaigui granules significantly regulated 12 metabolites including docosatrienoic acid, 3-hydroxybutyric acid, 4-hydroxybenzaldehyde, chenodeoxycholic acid, cholic acid, L-glutamine, glycocholic acid, linoleyl carnitine, L-tyrosine, N-acetylvaline, palmitoylcarnitine, arachidonic acid. Further network analysis of the key metabolites regulated by Chaigui granules indicated that plasma arachidonic acid metabolism might be the core pathway for the antidepressant effect of Chaigui granules, with 10 proteins were potential targets for the antidepressant effect of Chaigui granules, including CYP2B6, CYP2E1, CYP2C9, CYP2C8, PLA2G6, PTGS2, ALOX15B, PTGS1, ALOX12 and ALOX5.
