ABSTRACT

OBJECTIVE@#To evaluate the impact of a history of vaginal delivery on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation.@*METHODS@#Ninety-nine patients undergoing hysteroscopic surgery under intravenous general anesthesia were enrolled in this study, including 43 patients with (VD group) and 56 patients without a history of vaginal delivery (NVD group). For all the patients, blood pressure, heart rate (HR), blood oxygen saturation (SpO2) and bispectral index (BIS) were recorded before anesthesia (T1), after anesthesia (T2), after cervical dilation (T3), and at 3 min after cervical dilation (T4). Propofol and etomidate doses during anesthesia induction, the total dose of propofol administered, additional intraoperative bolus dose and times of propofol, intraoperative body movement, total operation time and surgeons' satisfaction feedback scores were compared between the two groups. The postoperative awake time, recovery time, VAS score at 30 min after operation, and postoperative nausea and vomiting (PONV) were also compared.@*RESULTS@#There was no significant differences in SBP, DBP, HR, SpO2, or BIS between the two groups at T1 and T2, but at T3 and T4, SBP and DBP were significantly higher in NVD group than in VD group (P < 0.01); HR was significantly higher in NVD group only at T3 (P < 0.01). The application of vasoactive drugs did not differ significantly between the two groups. The total dose of propofol, additional intraoperative dose and times of propofol were all greater in NVD group than in VD group (P < 0.01). More body movements of the patients were observed in NVD group (P < 0.01), which also had lower surgeons' satisfaction score for anesthesia (P < 0.01), higher postoperative VAS score (P < 0.05), and shorter postoperative awake time (P < 0.05) and recovery time (P < 0.01).@*CONCLUSION@#A history of vaginal delivery has a significant impact on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation in terms of hemodynamic changes, anesthetic medication, and postoperative recovery quality, suggesting the necessity of individualized anesthesia management for these patients.

ABSTRACT

Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

ABSTRACT

WRKY, a class of conserved transcription factors in plants, plays important roles in plant growth, development and secondary metabolism. In the present study, 65 WRKY members were identified from de novo transcriptome sequencing data of three different tissues (root, stems and leaves) of Baphicacanthus cusia. BcWRKY proteins contained from 221 to 706 amino acids and the isoelectric point is from 4.68 to 9.68. Molecular weights range from 25 711.8 to 75 475 Da. The main secondary structures of BcWRKYs protein are random coil. A subcellular localization prediction indicated that the putative BcWRKY proteins were enriched in the nuclear region. Phylogenetic analysis showed that BcWRKYs could be categorized into three groups and five subgroups (Group IIa, Group IIb, Group IIc, Group IId and Group IIe) in Group II. Structural analysis found that all BcWRKY proteins contained a highly conserved motif WRKYGQK. Finally, the transcriptional profiles of ten BcWRKY genes highly expressed in root, stem and leaf tissues under abscisic acid (ABA), methyl jasmonate (MeJA), or salicylic acid (SA) treatment were systematically investigated using qRT-PCR analysis. Results showed that a total of ten BcWRKY genes were differentially expressed in response to ABA, MeJA, and SA treatment. This work would be provided a basis for further elucidating the molecular mechanism of WRKY transcription factors in the biosynthesis of indole alkaloids in B. cusia.

ABSTRACT

Autophagy is a lysosome-mediated catabolic process that captures and degrades dysfunctional organelles and useless proteins during cellular stress process, which plays a dual role in cervical cancer. In the early stage of cervical cancer, autophagy inhibits the occurrence and development of cervical cancer by prohibiting the accumulation of oncogenic p62 protein. In the advanced stage of cervical cancer, inhibition of autophagy of cancer cells enhances the sensitivity of cancer cells to chemotherapeutic drugs, thus inhibiting their proliferation. In recent years, the research on Chinese medicine monomers regulating autophagy in the treatment of cervical cancer has attracted extensive attention from scholars at home and abroad. Chinese medicine monomers regulate the autophagy of cervical cancer cells through multiple pathways and multiple targets, so as to increase the apoptosis rate and reduce the resistance of cancer cells to chemotherapeutic drugs. Therefore, this paper reviewed the mechanism of Chinese medicine monomers in inhibiting cervical cancer through autophagy, expecting to find new breakthroughs in the discovery and development of preventive and therapeutic drugs for cervical cancer. By reviewing the literature, it was found that in the early stage of cervical cancer, Chinese medicine monomers activated autophagy to promote apoptosis of cancer cells, and the main mechanism was to increase lysosomal membrane permeability and chemotherapeutic sensitivity and activate intact autophagy flow. In the advanced stage of cervical cancer, inhibition of autophagy reduced the sensitivity of cancer cells to chemotherapy drugs by inhibiting the formation of autophagosomes and autolysosomes. The treatment of cervical cancer by Chinese medicine monomers regulating autophagy has achieved certain effect, but there are few clinical experimental studies and lack of reliable clinical theoretical basis. Therefore, it is essential to carry out more clinical experimental studies on Chinese medicine monomers regulating autophagy to treat cervical cancer, thus finding more reliable theoretical basis for the treatment of tumors.

ABSTRACT

Objective: To evaluate the effectiveness and safety of Pul-Stent as the treatment of postoperative branch pulmonary artery stenosis in children with congenital heart disease. Methods: This was a retrospective study. Thirty-three patients who underwent Pul-Stent implantation in Shanghai Children's Medical Center due to postoperative residual pulmonary artery stenosis from August 2014 to June 2015 were included. The immediate curative effect, follow-up and complications of Pul-Stent implantation were assessed. Comparisons between groups were performed with unpaired Student t test. Results: Pul-Stent implantation of 33 patients (19 males and 14 females) were performed successfully. Thirty-one patients underwent percutaneous stenting, and 2 patients underwent hybrid stenting. A total of 35 Pul-Stents were implanted (19 of model small, 15 of model medium and one of model large), 23 stents were planted in the proximal left pulmonary artery and 12 stents were in the proximal right pulmonary artery. The initial diameter of dilation balloon ranged from 6 to 16 mm, and the long sheath of percutaneous implantation ranged from 8 to 10 F in 29 patients (29/31, 94%). After stenting, the diameter of the narrowest segment of pulmonary artery increased from (4.0±1.7) mm to (9.1±2.1) mm in all patients (t=-21.60, P<0.001). The pressure gradient at the stenosis in 26 patients after biventricular correction decreased from (30.5±12.3) mmHg (1 mmHg=0.133 kPa) to (9.9±9.6) mmHg (t=12.92, P<0.001), and the right ventricular to aortic pressure ratio decreased from 0.57±0.14 to 0.44±0.12 (t=7.44, P<0.001). The pressure of the superior vena cava after stenting in 5 patients after cavopulmonary anastomosis decreased from (17.0±1.9) mmHg to (14.0±0.7) mmHg (t=2.86, P=0.046). Two patients died during reoperation for repairing other cardiac malformations. The remaining 31 patients were clinically stable during the follow-up period of (5.3±1.6) years, and one stent fracture was found on chest X-ray. Cardiac catheterization reexaminations in 16 patients showed that restenosis was found in one stent, while stent position and patency were satisfactory in the remaining stents. Nine children underwent post-dilation without stent fracture, displacement or aneurysm formation. Cardiac tomography showed no stent stenosis, fracture observed, or significant change in diameter of the stent in 8 patients. The inner diameter and pulmonary blood perfusion could not be accurately evaluated due to artifacts by cardiac magnetic resonance imaging in 4 patients. Conclusions: Pul-Stent has good compliance and adequate radial strength, and can dilate further over time to accommodate for somatic growth. It performs safely and effectively in treating post-operative branch pulmonary artery stenosis in children.

ABSTRACT

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

ABSTRACT

Objective:To observe and analyze the correlation between time within target glucose range (TIR) and hemoglobin A1c (HbA1c) and the risk of diabetic retinopathy (DR).Methods:A retrospective clinical study. From March 2020 to August 2021, 91 patients with type 2 diabetes mellitus (T2DM) who were hospitalized in Department of Endocrinology and Metabolic Diseases, Affiliated Hospital of Weifang Medical University, were included in the study. All patients underwent Oburg's no-dilatation ultra-wide-angle laser scan ophthalmoscopy, HbA1c and continuous glucose monitoring (CGM) examinations. According to the examination results and combined with the clinical diagnostic criteria of DR, the patients were divided into non-DR (NDR) group and DR group, with 50 and 41 cases respectively. The retrospective CGM system was used to monitor the subcutaneous interstitial fluid glucose for 7 to 14 consecutive days, and the TIR was calculated. Binary logistic regression was used to analyze the correlation between TIR, HbAlc and DR in patients with T2DM0. At the same time, a new indicator was generated, the predicted probability value (PRE_1), which was generated to represent the combined indicator of TIR and HbA1c in predicting the occurrence of DR. The receiver operating characteristic curve (ROC curve) was used to analyze the value of TIR, HbAlc and PRE_1 in predicting the occurrence of DR.Results:The TIR of patients in the NDR group and DR group were (81.58±15.51)% and (67.27±22.09)%, respectively, and HbA1c were (8.03±2.16)% and (9.01±2.01)%, respectively. The differences in TIR and HbA1c between the two groups of patients were statistically significant ( t=3.501,-2.208; P=0.001, 0.030). The results of binary logistic regression analysis showed that TIR, HbA1c and DR were significantly correlated (odds ratio=0.960, 1.254; P=0.002, 0.036). ROC curve analysis results showed that the area under the ROC curve (AUC) of TIR, HbA1c and PRE_1 predicting the risk of DR were 0.704, 0.668, and 0.707, respectively [95% confidence interval ( CI) 0.597-0.812, P=0.001; 95% CI 0.558-0.778, P=0.006; 95% CI 0.602-0.798, P=0.001]. There was no statistically significant difference between TIR, HbA1c and PRE_1 predicting the AUC of DR risk ( P>0.05). The linear equation between HbAlc and TIR was HbAlc (%) = 11.37-0.04×TIR (%). Conclusions:TIR and HbA1c are both related to DR and can predict the risk of DR. The combined use of the two does not improve the predictive value of DR. There is a linear correlation between TIR and HbAlc.

ABSTRACT

Objective:To observe any effect of supplementing continuous static stretching (CSS) with extracorporeal shock wave therapy (ESWT) in treating triceps surae spasm after a stroke.Methods:Sixty-four stroke survivors with triceps surae spasm were randomly divided into a conventional rehabilitation group, a shock wave group and a combined treatment group. In addition to conventional rehabilitation, the shock wave group received extracorporeal shock wave therapy twice a week and the combined treatment group received the shock waves during continuous static stretching. After 6 weeks of treatment all of the subjects were assessed using the Modified Ashworth Scale (MAS), the Fugl-Meyer Assessment (FMA) and Brunnstrom classification of their functional recovery stage.Results:Before treatment there was no significant difference among the three groups. After the 6 weeks of treatment the average triceps surae tension in all three groups had eased significantly. At that point the average MAS and FMA scores of the shock wave group and the combined treatment group were significantly better than those of the conventional group. The combined treatment group then showed significantly better therapeutic effect than the shock wave group.Conclusions:Applying extracorporeal shock waves during continuous static stretching can significantly improve the stretching′s ability to reduce spasticity and improve motor functioning, at least of the triceps surae. Combining shock waves with modern traction methods is recommended for clinical application.

ABSTRACT

Primary hypomagnesemia with secondary hypocalcemia(HSH) is a rare cause of hypoparathyroidism. This article presents a case of a 26-year-old male with recurrent generalized weakness and tetany, and a literature review of diagnosis and treatment of primary HSH. The biochemical tests revealed the patient had severe hypomagnesemia, mild hypocalcemia, hypokalemia, and hypoparathyroidism. Transient receptor potential melastatin-6(TRPM6) gene mutation were detected by gene test, which confirmed the diagnosis of primary HSH. The patient had been treated with long term oral magnesium supplementation, who remained asymptomatic during the follow-up. Primary HSH is a rare autosomal-recessive disorder caused by mutations in the TRPM6 gene which encoding a magnesium permeable channel expressed in the intestine and the kidney. The primary defect is impaired intestinal absorption of magnesium with secondary renal excretion, leading to a series of clinical symptoms. The treatment is mainly through lifelong magnesium supplementation.

ABSTRACT

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

ABSTRACT

Objective:To explore the clinical characteristics, therapeutic efficacy and prognosis of congenital coronary artery fistula (CAF) in children.Methods:Clinical data of 71 pediatric patients diagnosed with congenital CAF at Department of Cardiology and Department of Cardiac Surgery, Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine from January 2013 to June 2019 were retrospectively analyzed.The median age was 2.2 years (0.1-14.0 years), and the median body weight was 18.3 kg (3.2-55.8 kg), including 37 males (52.1%) and 34 females (47.9%). They were divided into the transcatheter closure group (30 cases) and surgical repair group (41 cases). The therapeutic effect and follow-up data of the 2 groups were compared by the Fisher′ s exact test. Results:Among the 71 congenital CAF children, 70 had heart murmurs, 2 had chest tightness after activity, and 5 were prone to recurrent respiratory tract infection.Transcatheter closure and surgical repair were successfully performed in 22/30 (73.3%) and 41/41 (100.0%) cases with a statistically significant difference ( P=0.001). However, in the surgical repair group, 1 (2.4%) case died after operation and 2(4.9%) needed further transcatheter closure due to large residual shunt during the follow-up period.At the last follow-up, there were 2 cases with minimal or small residual shunt in both groups ( P=0.567). There were 2/71(2.8%) cases suffering from postoperative thrombosis. Conclusions:Cardiac murmur is the main sign of congenital CAF in children, and some of them may have frequent respiratory tract infection due to increased lung blood caused by a large amount of shunt.A few children have chest tightness and chest pain due to myocardial ischemia caused by coronary steal.Both percutaneous closure and surgical repair are safe and effective with few complications.

ABSTRACT

This study aims to develop an HPLC-DAD method for simultaneous determination of 11 components(6 phenolic acids and 5 iridoids) in Lonicera japonica flowers(LjF) and leaves(LjL), and compare the content differences of LjF at different development stages, LjL at different maturity levels, and between LjF and LjL. One-way ANOVA, principal component analysis(PCA), and orthogonal partial least-squares discriminant analysis(OPLS-DA) were employed to compare the content of the 11 components. The content of total phenolic acids, total iridoid glycosides, and total 11 components in LjF showed an overall downward trend with the development of flowers. The content of total phenolic acids, total iridoid glycosides, and total 11 components in young leaves were higher than those in mature leaves. The results of PCA showed that the samples at different flowering stages had distinguishable differences in component content. The VIP value of OPLS-DA showed that isochlorogenic acid A, chlorogenic acid, and secologanic acid were the main differential components of LjF at different development stages or LjL with different maturity levels. LjF and LjL have certain similarities in chemical composition while significant differences in component content. The content of total phenolic acids in young leaves was significantly higher than that in LjF at various development stages. The content of total iridoid glycosides in young leaves was similar to that in LjF before white flower bud stage. The total content of 11 components in young leaves was significantly higher than that in LjF at green flower bud stage, before and during completely white flower bud stage. LjL have great potential for development. Follow-up research on the pharmacodynamic equivalence of LjF and LjL(especially young leaves) should be carried out to speed up the development and application of LjL.

ABSTRACT

Objective:To evaluate the effect of electroacupuncture (EA) on pyroptosis in renal tubular epithelial cells of rats with acute kidney injury (AKI) induced by endotoxin.Methods:Twenty-four healthy clean-grade Sprague-Dawley rats of either gender, aged 6-8 weeks, weighing 160-182 g, were divided into 4 groups ( n=6 each) using a random number table method: control group (group C), group AKI, EA plus AKI group (group EA), sham EA at non-acupoint plus AKI group (group SEA). The model of endotoxemia was established by intraperitoneally injecting 10 mg/kg lipopolysaccharide.Bilateral 30 min EA stimulation of Zusanli and Shenyu (according to atlas of animal acupoint) was performed starting from 5 days before establishing the model (once a day) and at 30 min before lipopolysaccharide administration on the day of establishing the model, with disperse-dense waves, frequency of 15 Hz, and the needle was kept until 6 h after injection of LPS in group EA.EA was performed at the points 0.5 cm lateral to the acupoints of Zusanli and Shenyu in group SEA.At 6 h after LPS injection, blood was taken from the heart, and the concentrations of serum blood urea nitrogen (BUN) and creatinine (Cr) were detected by an automatic biochemical analyzer, and the serum concentrations of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) by enzyme-linked immunosorbent assay.The rats were then sacrificed, and the left renal cortex was obtained for determination of pyroptosis rate of renal tubular epithelial cells (by TUNEL). The right renal cortex was obtained to detect the expression of caspase-1 and IL-1β by Western blot, and the expression of caspase-1 mRNA and IL-1β mRNA was detected by real-time polymerase chain reaction. Results:Compared with group C, the concentrations of BUN, Cr, NGAL, KIM-1, TNF-α, and IL-6 were significantly increased, the pyroptosis rate of renal tubular epithelial cells was increased, the expression of caspase-1 and IL-1β protein and mRNA in the renal cortex was up-regulated in group AKI ( P<0.05). Compared with group AKI, the concentrations of BUN, Cr, NGAL, KIM-1, TNF-α, and IL-6 were significantly decreased, the pyroptosis rate of renal tubular epithelial cells was decreased, the expression of caspase-1 and IL-1β protein and mRNA in the renal cortex was down-regulated in group SEA ( P>0.05). Conclusion:The mechanism by which EA reduces AKI may be related to inhibiting pyroptosis in renal tubular epithelial cells of rats.

ABSTRACT

Objective:To probe the influence of obstruction sleep apnea syndrome (OSAS) on cardiac function and serum cystatin-C (CC) levels in patients with chronic heart failure (CHF), and to discuss its clinical significance.Methods:129 CHF patients suspected of OSAS were selected and divided into observation group (with apnea) and control group (without apnea) according to sleep apnea hypopnea index (AHI). The observation group included mild, moderate and severe groups. After admission, the levels of left ventricular ejection fraction (LVEF), N-terminal forebrain natriuretic peptide (NT-proBNP) and CC were collected for further analysis.Results:The levels of NT-proBNP and CC in 99 patients with CHF complicated with OSAS were higher than those in the control group, while LVEF was lower than those in the control group ( P<0.05); The levels of NT-proBNP and CC in severe group were higher than those in mild and moderate group, while LVEF was significantly lower ( P<0.05); The level of CC in mild to moderate group was higher than that in control group, while LVEF was lower than that in control group ( P<0.05). Rank correlation analysis showed that CC was positively correlated with AHI ( r=0.726, P<0.01); However, there was no significant difference in NT proBNP between mild to moderate group and control group ( P>0.05). Conclusions:OSAS can lead to the deterioration of cardiac function. The CC of CHF patients with OSAS is higher and increases with the aggravation of obstruction. CC may participate in the progression of the disease. A high level of CC may aggravate the development of the disease, and the incidence and mortality of cardiovascular events may also increase.Early prevention and treatment should be given.

ABSTRACT

Objective:To investigate clinical features and prognosis of purulent meningitis in premature infants versus full-term infants and to better understand purulent meningitis and improve the diagnosis and treatment of purulent meningitis in infants. Methods:The clinical data of 54 infants with purulent meningitis who received treatment in Shanxi Children's Hospital, China between January 2017 and December 2019 were included in this study. The included infants were divided into preterm group (gestational age < 37 weeks, n = 11) and full-term group (gestational age 37-42 weeks, n = 43) according to different gestational ages. Clinical features and cerebrospinal fluid biochemical indexes (white blood cell count, protein concentration, glucose level) as well as total effective rate were compared between the preterm and full-term groups. Results:The main clinical features of neonatal purulent meningitis were fever, bradykinesia, low amount of milk intake, convulsion, lethargy, irritability, increased intracranial pressure, hypotonia or hypertonia. Hypotonia was the prominent manifestation in the preterm group, while fever, convulsion and bradykinesia were the prominent manifestations in the full-term group. White blood cell count and cerebrospinal fluid glucose level in the preterm group were significantly higher than those in the full-term group ( t = 2.215, 2.023, both P < 0.05), but cerebrospinal fluid protein level in the preterm group was significantly higher than that in the full-term group ( t = 2.437, P < 0.05). There was no significant difference in total effective rate between preterm and full-term groups [90.91% (10/11) vs. 90.70% (39/43), χ2 = 0.001, P > 0.05]. Conclusion:The clinical features of neonatal purulent meningitis are not specific, and the clinical features of premature infants with purulent meningitis are not typical. It is necessary to carefully observe the clinical manifestations of premature infants with purulent meningitis and detect the biochemical indexes of cerebrospinal fluid to strive for early diagnosis and treatment.

ABSTRACT

Objective:To explore the biochemical characteristics, virulence factors and other phenotypes of the strains of Yersinia pestis isolated in Jianchuan County Yunnan Province in 2017, and to analyze the nature and source of the new plague epidemic. Methods:Three strains of Yersinia pestis (JC109 rat, JC109 fleas and JC113) isolated from Daqing Village, Jinhua Town, Jianchuan County, Dali Prefecture, Yunnan Province in 2017, and 2 associated strains of Yersinia pestis (LJ01 in Yulong County, Lijiang City and LJ04 in Gucheng District of Lijiang City), 5 control strains ( Yersinia pestis JC1332, LJ485, BN2636, EV-76 and Yersinia pseudotuberculosis PST-1), preserved by the Central Laboratory of Yunnan Institute for Endemic Disease Control and Prevention were collected. The biochemical characteristics and ecotypes of Yersinia pestis were analyzed by using arabinose, rhamnose, denbiose, maltose and glycerol fermentation experiments and nitrate reduction experiments. Combining pigmentation factor (pgm), virulence antigen (VW) detection and nutritional requirements test results to determine the virulence of Yersinia pestis. Results:The Yersinia pestis JC109 rat, JC109 fleas and JC113 all fermented arabinose, maltose and glycerol, but didn't ferment rhamnose and denbiose; and the nitrate reduction test was positive. The ecological type belonged to the Himalayan Marmot plague strain of Qinghai-Tibet plateau. The virulence factors pgm and VW tests were positive, the nutritional requirement type was phenylalanine dependent and glutamate independent. It had the same phenotype as the LJ01 strain, but different from the JC1332 strain. Conclusions:The newly isolated strains in Jianchuan County are the same as those in the Lijiang Yulong wild rodent plague foci. This outbreak may have been imported from the Lijiang Yulong wild rodent plague foci to the south.

ABSTRACT

Objective:To observe the clinical effect of acupuncture treatment based on Tiaoshen theory for the patients with functional dyspepsia (FD) and depression with liver-stomach disharmony syndrome. Methods:A total of 76 FD patients from May 2018 to August 2019 were randomly divided into 2 groups with 38 patients in each group. In the routine group, acupoints were selected routinely, and in Tiaoshen group, acupoints were selected by Tiaoshen theory. Both groups were treated for 28 days. The results were evaluated by Nepean Dyspepsia Index (NDI), TCM Syndrome Score and Hamilton Depression Scale-24 (HAMD-24). Results:The total effective rate of both groups was 94.6% (35/37) in Tiaoshen group and 75.0% (27/36) in routine group. There was significant difference between the two groups ( χ2=6.125, P=0.011). The NDI in Tiaoshen group was significantly lower than that of routine group ( t=3.038, P=0.003). The scores of interference domain, control domain, food and beverage domain and sleep disturbance domain in Tiaoshen group were significantly higher than those in routine group ( t=3.096, 2.460, 2.225, 2.732, P<0.05); the TCM Syndrome Score in Tiaoshen group was significantly lower than that of routine group ( t=3.241, P=0.002), and that of HAMD-24 was significantly lower than that of routine group ( t=2.767, P=0.007). Conclusion:Treatment based on Tiaoshen theory can improve the quality of life of FD patients in the fields of interference, control, food and beverage and sleep disturbance, and reduce the patients’depression.
