ABSTRACT

Since December 2019, a pneumonia caused by a new coronavirus, i.e. COVID-19 occurred in Wuhan, Hubei Province, China. Although the epidemic in China has been bought under control, the global COVID-19 situation is still grim. Severe traumatic brain injury (TBI), as one of critical conditions in the department of neurosurgery, requires an early and effective treatment, especially surgery. There were currently no reliable guidelines on how to perform perioperative protection in TBI patients with suspected or confirmed coronavirus infection. According to the corresponding treatment regulations and guidelines issued by the authorities, we summarized the management strategy of TBI patients in perioperative period during the COVID-19 outbreak based on medical and nursing practice, in order to provide a reference for clinicians.

ABSTRACT

Bile acids( BAs),the major constituents of bile,are also known to be potential biomarkers of various diseases,especially liver disease. The systematic analysis of BAs is believed to be of great importance towards the clarification of the effective material basis for bile-type medicines,and the diagnosis and therapy of related diseases as well. As a part of systematic study on bile-type medicine ongoing in our group,this study lays emphasis on the isomer discrimination,and the improvement of analytical method of BAs. Further,this method was subsequently applied to elucidate in depth the chemical profile of BAs in yak bile. Regarding isomer discrimination for BAs,we constructed relative response-collision energy curves( RRCECs) by high performance liquid chromatographyion trap-time of flight-mass spectrometry( HPLC-IT-TOF-MS) in combination with high performance liquid chromatography-triple quadrupole-linear ion trap mass spectrometry( HPLC-Qtrap-MS). As a result,both the optimum collision energy( OCE) and CE_(50) exhibited great correlations with structural characteristics,thus enabling the isomer distinguishing,such as unconjugated BAs,glycine-conjugated BAs,and taurine-conjugated BAs. According to information provided by mass spectrometry,the comparison of OCE and CE_(50),retention time matching,combined with reference substances and database retrieval,a total of 30 bile acid derivatives were observed and identified in yak bile. The newly developed method could serve as a feasible tool for the in-depth characterization of BAs in bile and biological samples.

ABSTRACT

Objective: To explore the lipid-lowering effect and potential mechanism of the couplet medicines of Flastem Milkvetch Seed and Tribulus terrestris on hyperlipidemia rats. Methods: Forty-eight Sprague-Dawley rats were randomly divided into 6 groups, normal control group, high-fat model group, simvastatin group, Tribulus terrestris group, Flastem Milkvetch Seed group, and couplet medicines of Flastem Milkvetch Seed and Tribulus terrestris group, with 8 rats in each group. The normal control group was fed with basal diet, and the other groups were fed with high-fat diet to establish a hyperlipidemia rat model. At the same time, different group rats were treated with different drug respectively. 6 weeks later, the body weight and visceral index of the rats were measured. Levels of serum cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were detected by automatic biochemical analyzer. The mRNA and protein expression of HMG coenzyme A reductase (HMGCR), cholesterol 7-alpha hydroxy-lase (CYP7A1) and low density lipoprotein receptor (LDL-R) were detected by RT-PCR and western blot. Results: Compared with model group, the serum levels of TC, TG, and LDL-C were significantly decreased in all Chinese medicine groups, and the serum level of HDL-C was significantly increased in Flastem Milkvetch Seed group and couplet medicines of Flastem Milkvetch Seed and Tribulus terrestris group. Moreover, the mRNA and protein expression of HMGCR, CYP7A1, and LDL-R in rat liver also significantly increased in all Chinese medicine treatment groups. And couplet medicines of Flastem Milkvetch Seed and Tribulus terrestris group shows more significantly effect. Conclusion: Couplet medicines of Flastem Milkvetch Seed and Tribulus terrestris significantly regulate the serum lipid levels on hyperlipidemia rat model, and its mechanism may be related to the regulating expressions of HMGCR, CYP7A1, LDL-R gene.

ABSTRACT

AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation. METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed. RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation. CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

ABSTRACT

<p><b>BACKGROUND</b>The prevalence of malnutrition is very high in patients with cancer. The purpose of this study was to investigate whether or not a nutrition support team (NST) could benefit esophageal cancer patients undergoing chemoradiotherapy (CRT).</p><p><b>METHODS</b>Between June 2012 and April 2014, 50 esophageal cancer patients undergoing concurrent CRT were randomly assigned into two groups: The NST group and the control group. The nutritional statuses of 25 patients in the NST group were managed by the NST. The other 25 patients in the control group underwent the supervision of radiotherapy practitioners. At the end of the CRT, nutritional status, the incidence of complications, and completion rate of radiotherapy were evaluated. Besides, the length of hospital stay (LOS) and the in-patient cost were also compared between these two groups.</p><p><b>RESULTS</b>At the completion of CRF, the nutritional status in the NST group were much better than those in the control group, as evidenced by prealbumin (ALB), transferrin, and ALB parameters (P = 0.001, 0.000, and 0.000, respectively). The complication incidences, including bone marrow suppression (20% vs. 48%, P = 0.037) and complications related infections (12% vs. 44%, P = 0.012), in the NST group were lower and significantly different from the control group. In addition, only one patient in the NST group did not complete the planned radiotherapy while 6 patients in the control group had interrupted or delayed radiotherapy (96% vs. 76%, P = 0.103). Furthermore, the average LOS was decreased by 4.5 days (P = 0.001) and in-patient cost was reduced to 1.26 ± 0.75 thousand US dollars person-times (P > 0.05) in the NST group.</p><p><b>CONCLUSIONS</b>A NST could provide positive effects in esophageal cancer patients during concurrent CRT on maintaining their nutrition status and improving the compliance of CRF. Moreover, the NST could be helpful on reducing LOS and in-patient costs.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of application of percutaneous radiofrequency ablation (RFA) with artificial hydrothorax for liver cancer in the hepatic dome.</p><p><b>METHODS</b>Thirty-two patients with 43 lesions of hepatic malignant tumors in the hepatic dome underwent ultrasound-guided percutaneous radiofrequency ablation (RFA) with artificial hydrothorax. Artificial hydrothorax was created by infusion of saline via an intrathoracically placed 14-G central venous catheter, which was ultrasound-guided percutaneously inserted before RFA, separating the right lung from the hepatic dome. The adverse reaction and therapeutic efficacy were also analyzed.</p><p><b>RESULTS</b>In the 32 patients with 43 lesions in the hepatic dome (4 tumors in segment IV 21 tumors in segment VII and 18 tumors in segment VIII), 18 lesions of 14 patients were not observed by ultrasound before the operation. Thirty-two patients received the ultrasound-guided placement of intrathoracical catheter, and (1606.3 ± 485.9) ml (1000 - 2500 ml) saline solution was infused successfully. After obtaining an image of the whole tumor, 31 patients received percutaneous RFA therapy on schedule, and 22 patients received percutaneous transdiaphragmatic RFA therapy. One patient with 2 lesions gave up the treatment, because one of his tumors was not detectable by ultrasound. Diaphragmatic muscle hemorrhage was seen in two patients, subcutaneous edema in two patients, and pneumothorax in one patient. All the complications were cured, and no serious complications or related death occurred. 1-month follow-up with contrast-enhanced CT/MRI images showed that 29 patients had complete ablation, and the effective rate of this technique was 93.5% (29/31).</p><p><b>CONCLUSIONS</b>Artificial hydrothorax helps us not only to visualize the whole tumor in the hepatic dome, but also offers a transdiaphragmatic route for therapy. Ultrasound-guided percutaneous RFA with artificial hydrothorax is a feasible, safe, and effective technique for treating liver cancer in the hepatic dome and worthy of being promoted.</p>

ABSTRACT

Objective To compare the effect of percutaneons coronary interventions (PCI) combined with polydanshinolate on myocardial reperfusion with PCI combined with regular medicine in patients with acute myocardi-al infrarction ,and whether polydanshinolate would decrease no-reflow,improve the myocardial micro-circulation and the ventricular remodeling and clinical end-point events at the sixth month. Methods Random,parallel control and prospective clinical design was used in the current study. Sixty eligible patients for PCI, who were diagnosed as first-time acute myocardial infrarction with ST stage increasing,were recruited in the study with informed consent. All par-ticipants were divided into two groups randomly. Group A was treated with PCI combined with polydanshinolate, group B was treated with PCI combined with regular medicine. The participants were followed up for six months. The resolution of the sum of ST segment elevation (sum STR) ,corrected TIMI frame count (CTFC) and myocardial con-trast echocardiography (MCE) were used to assess myocardial perfusion. Bleeding events, heart function and major adverse cardiac events (MACE) were observed during hospitalization and follow-up visit. Results No significant difference was observed between two groups on the clinical condition and the results of emergency CAG and PCI. Compared to group B,the incidence of TIMI grade 3 was significantly higher in group A (90.0% vs 63.3% ,χ~2 = 4.565, P=0.0326). Sum STR one hour after PCI in group A was siguificanfly higher than that in group B (80.0% vs 50.0%, χ~2=4.689, P=0.0304). CTFC after PCI also differed significantly between the two groups (24.1±8.3 vs 33.4±15.9 respectively,P=0.0062). Localized myocardial blood flow 48 hours after PCI showed no significant difference between the two groups (P>0.05), whereas both increased at the 7th day after PCI (5.85±1.26 vs 2.09±1.85,t=9.2008,P<0.0001 ;3.95±1.35 vs 1.95±1.29,t=5.8666,P<0.0001) ,and there were signifi-cant difference between the two groups (P<0.05). No significant difference of LVEF, LVEDV, LVESV were found between the two groups during the hospitalization and follow-up visit after 6 months (P>0.05). The incidences of cardiovascular events and severe heart failure during hospitalization and follow-up visit in group A were significantly lower than that in group B (P<0.05 ). Conclusions Polydanshinolate addition to PCI could reduce no reflow phe-nomenan in patients of acute myocardial infrarction, improve myocardial reperfusion, and furthermore, decrease cardi-ovascular events and ameliorate prognosis.

ABSTRACT

<p><b>OBJECTIVES</b>Ventricular remodeling is an important pathologic progress in almost all end stage heart failure (HF), and it is characterized by ventricular thickening and cardiac fibrosis with poor prognosis. The connective tissue growth factor (CTGF), a new growth factor with multi-function, has an important role in fibrosis of tissue and organs. It has been demonstrated that angiotensin-converting enzyme inhibitor (ACEI) can prevent the development of cardiomyocyte from remodeling and improve cardiac function. Researchers try to test the hypothesis that cardiac function improvement attributable to ACEI is associated with inhibiting expression of CTGF in patients with HF. The aim of this study was to observe changes in CTGF expression in cardiomyocyte of young rats with HF and effect of benazepril on CTGF.</p><p><b>METHODS</b>The animal model of HF was established by constriction of abdominal aorta. Five weeks old rats were randomly divided into 3 groups after 6 weeks of operation: (1) HF group without treatment (n = 15); (2) HF group where rats were treated with benazepril (n = 15); (3) sham-operated group (n = 15) where rats were administered benazepril through direct gastric gavage. After 4 weeks of treatment, the high frequency ultrasound was performed. The expression of CTGF was detected by immunohistochemistry and semi-quantative reverse transcription-polymerase chain reaction.</p><p><b>RESULTS</b>Compared with the sham-operated group, left ventricular diastolic dimension (LVEDD), left ventricular systolic dimension (LVESD), interventricular septal thickness at end-diastole (IVSTd), interventricular septal thickness at end-systole (IVSTs), left ventricular posterior wall thickness at end-diastole (LVPWTd), left ventricular posterior wall thickness at end-systole (LVPWTs), left ventricular relative weight (LVRW), and right ventricular relative weight (RVRW) were all increased (P < 0.01), but ejection fraction (EF) and fractional shortening (FS) were decreased (P < 0.01). CTGF positive cells and expression of CTGF mRNA (0.609 +/- 0.065 vs 0.117 +/- 0.011, P < 0.01) were increased in HF group without treatment. LVESD, IVSTd, IVSTs, LVPWTd, LVPWTs, LVRW and RVRW were all decreased (P < 0.01), but FS and EF were increased (P < 0.01) in cases of HF treated with benazepril when compared with HF group without treatment. LVESD, IVSTd, IVSTs, LVPWTd, LVPWTs, LVRW and RVRW were higher (P < 0.01), EF and FS were lower (P < 0.01), CTGF positive cells and expression of CTGF mRNA were higher (P < 0.01) in HF group treated with benazepril than those of sham-operated group.</p><p><b>CONCLUSION</b>The expression of CTGF was increased in the cardiomyocyte of young rats with HF and benazepril could prevent left ventricular from remodeling partly and improve cardiac function by inhibiting the expression of CTGF in cardiomyocyte in cases of HF.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the impact of Foxp3 expression and CD(4)(+)CD(25)(+) regulatory T cells on pathogenesis of childhood asthma.</p><p><b>METHODS</b>Totally 15 patients with acute asthma exacerbation, 15 children with asthma remission and 10 children who were hospitalized for skeleton deformity without atopic disorders or history of allergic diseases or respiratory infections within a month as controls were recruited in this study from Sep. 2004 to Mar. 2005. The percentage of CD(4)(+)CD(25)(+) T cells were detected by 2-color flow cytometry. The levels of interleukin (IL)-4, IL-10, interferon (IFN)-gamma, transforming growth factor (TGF)-beta in plasma and supernatant were assayed by ELISA. Both the asthmatic children and the control children were selected to induce sputum by hypertonic saline. Sputum was processed for detecting the expression of Foxp3-mRNA. The expression of Foxp3-mRNA in both sputum and PBMC was detected by semi-quantitative RT-PCR with beta-actin as internal control.</p><p><b>RESULTS</b>The percentage of CD(4)(+)CD(25)(+) regulatory T cells in exacerbation and remission asthmatic children was significantly lower than that of the control children both prestimulation [(10.1 +/- 2.1)% vs. (15.5 +/- 2.7)%, (11.7 +/- 2.5)% vs. (15.5 +/- 2.7)%, P < 0.05] and poststimulation with PHA [(12.4 +/- 2.3)% vs. (26.9 +/- 3.8)%, (17.3 +/- 3.2)% vs. (26.9 +/- 3.8)%, P < 0.05]. The percentage of CD(4)(+)CD(25)(+) regulatory T cells was significantly higher after PHA stimulation in normal children [(15.5 +/- 2.7)% vs. (26.9 +/- 3.8)%, P < 0.01]. The expression of Foxp3-mRNA (Foxp3/beta-actin) in asthmatic children was significantly lower than that in the control children in both PBMC and induced sputum. The expression of Foxp3-mRNA in PBMC was significantly higher after PHA stimulation in the control children (0.77 +/- 0.22 vs. 1.07 +/- 0.21, P < 0.05). However, there was no significant difference in Foxp3-mRNA expression in asthmatic children pre and post PHA stimulation. A significant positive correlation between the Foxp3-mRNA expression and the percentage of CD(4)(+)CD(25)(+) regulatory T cells was detected. The levels of IFN-gamma and TGF-beta were significantly lower in asthmatic children than those in the control children, and the levels of IFN-gamma and TGF-beta correlated positively with Foxp3-mRNA expression and the percentage of CD(4)(+)CD(25)(+) regulatory T cells. The level of IL-4 both in plasma and supernatant was higher in asthmatic children. The levels of IL-10 was higher only in exacerbation than in control children, the levels of IL-4 and IL-10 had no correlation with Foxp3-mRNA expression and the percentage of CD(4)(+)CD(25)(+) regulatory T cells.</p><p><b>CONCLUSION</b>Insufficient secretion of TGF-beta, decreased Foxp3 expression, insufficient number of CD(4)(+)CD(25)(+) regulatory T cells and the defective ability of converting CD(4)(+)CD(25)(-) T cells to CD(4)(+)CD(25)(+) regulatory T cells might play an important role in pathogenesis of asthma.</p>
