AIM: To study the effects of neuregulin-1β (NRG-1β) on the nervous behavioral function, cerebral infarction volume, brain water content (BWC), neuroal apoptosis and aquaporin-4 (AQP-4) expression in astrocytes after cerebral ischemic reperfusion in mice. METHODS: Intraluminal thread methods were applied to establish the middle cerebral artery occlusion reperfusion (MCAO/R) model in mice. Neuregulin-1β (2 μg/kg) was injected into the internal carotid artery for treatment. The nervous behavioral function was evaluated by Bedersons test. The cerebral infarction volume was observed with tetrazolium chloride (TTC) staining. The BWC was measured by calculating the dry-wet weight ratio. The apoptotic positive cells were counted by immunofluorescence assay. The expression of AQP-4 was determined by immunohistochemical method. RESULTS: Nervous behavioral malfunction appeared in all the mice with left middle cerebral artery occlusion (MCAO) and/or reperfusion. The infarction focus showed in the ischemic hemisphere following the injury. The BWC, the numbers of neuroal apoptotic cells and AQP-4 expression in astrocytes were higher than those in sham control group. In MCAO/R+NRG-1β treatment group, the nervous behavioral function at ischemia 24 h significantly improved, the numbers of apoptotic positive cells reduced and the infarction volume decreased significantly than those in MCAO/R group (P<0.05). The BWC and AQP-4 expression in astrocytes showed no significant difference compared with MCAO/R group (P>0.05). In the reperfusion 22 h, 46 h and 70 h groups, the five indexes mentioned above were significantly different from those in the corresponding MCAO/R groups (P<0.05). CONCLUSION: NRG-1β might reduce cerebral edema and infarction volume, and improve the nervous behavioral function via down-regulating the expression of AQP-4 in astrocytes and inhibiting the neuronal apoptosis induced by ischemia reperfusion injury.

Objective To compare the curative efficacy and safety of subcutaneous immunotherapy (SCIT) versus sublingual immunotherapy (SLIT) for allergic rhinitis.Methods A total of 127 cases of patients with allergic rhinitis in the outpatient department of our hospital from June 2009 to March 2016 were retrospectively analyzed,including 79 cases treated with SCIT and 48 cases treated with SLIT.The curative effects and adverse reactions were compared between the two groups.Results After 3-year treatment,the total effective rate in the SCIT group was 75.9%,which was higher than 72.9% in the SLIT group,but the difference was not statistically significant (χ2=0.15,P>0.05).The incidence rate of adverse reactions in the SCIT group was 26.6%,which was higher than 10.4% in the SLIT group,the difference between the two groups was statistically significant (χ2=4.79,P<0.05).Conclusion The two desensitization treatment methods all gain better effect,but SLIT has lower occurrence rate of adverse reactions.

Objective To investigate the pain-relieving effectiveness of persistent epidural anesthesia and its influence on mothers and infants.Methods 40 pregnant women without any obstetric complications and anesthetic contraindications were selected as the observation group,and persistent epidural anesthesia were applied when the cervicis opened to be larger than 3cm.40 cases with similar obstetric conditions were regarded as the control group without using any anesthesia.We compared the degree of labor pain,duration,delivery mode,the incidence of postpartum hemorrhage,intrauterine distress,neonatal asphyxia between the two groups.Results There were significantly difference in the rate of oxytocin utilization,vaginal delivery and the time of stageⅡ labor.There were no obvious difference in the active phase of labor course,the incidence of cesarean birth,intrauterine distress,neonatal asphyxia and postpartum hemorrhage between the two groups.Conclusions The results indicate that epidural anesthesia could affect the length of stageⅡ labor time and have merits of simple,obvious analgetic effect,but inflecencing delivery mode,therefore it to be improve.

OBJECTIVE: To investigate the effects of Wenyang Huoxue Recipe (WRHXR), a compound traditional Chinese herbal medicine for warming yang and promoting blood flow, on the expression of angiopoietin mRNA in rats with chronic aristolochic acid nephropathy induced by Caulis Aristolochia Manshuriensis (CAM) decoction, and to explore the protection mechanism of WYHXR against kidney damage. METHODS: Twenty-eight male SD rats were randomly divided into normal control group, CAM group and WYHXR-treated group. Rats in the normal control group (n=8) and CAM group (n=10) were intragastrically administered with normal saline 10 ml/(kg.d) or CAM decoction 10 ml/(kg.d) respectively. Rats in the WYHXR-treated group (n=10) were intragastrically administered with WYHXR 30 g/(kg.d) and CAM decoction 10 ml/(kg.d). The expressions of Ang-l and Ang-2 mRNAs were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) after 20-week treatment. RESULTS: Compared with the normal control group, the expression of Ang-l mRNA was significantly decreased, and the expression of Ang-2 mRNA was significantly increased in the CAM group (P<0.01). Compared with the CAM group, the expression of Ang-l mRNA was increased in the WYHXR-treated group (P<0.01). The expression of Ang-2 mRNA had no significant difference between the CAM group and the WYHXR-treated group (P>0.05). Renal pathology showed that renal damage in WYHXR-treated group was significantly reduced as compared with the CAM group. CONCLUSION: WYHXR can up-regulate the expression of Ang-l mRNA, which may be its action mechanism in protecting the kidneys.

OBJECTIVE:To explore clinical efficacy and safety of Ulinastatin injection combined with Xingnaojing injec-tion in the treament of severe craniocerebral injury(CCI). METHODS:A total of 120 severe CCI patients selected from our hospital during Sept. 2014-Nov. 2015 were divided into ulinastatin group,Xingnaojing group and combination group according to therapy plan,with 40 cases in each group. Three groups were given routine treatment timely after admission. On the basis of routine treatment,Ulinastatin group additionally received Ulinastatin injection 200 000 U,ivgtt,bid;Xingnaojing group addi-tionally received Xingnaojing injection 20 mL,ivgtt,qd;combination group additionally received Ulinastatin injection com-bined with Xingnaojing injection,same usage as above(with 1 h intervals). Three groups received therapy for consecutive 14 d. Serum inflammatory factors(CRP,IL-1,IL-6,TNF-α),serologic indexes of craniocerebral injury [neuron specific enolase (NSE),myelin basic protein(MBP),S100B protein(S100B)] and GCS scores before and after treatment as well as GOS scores after treatment were all observed in 3 groups. The occurrence of ADR was recorded during treatment. RESULTS:Before treatment,there was no statistical significance in serum inflammatory factors,serologic indexes of craniocerebral injury or GCS scores among 3 groups(P>0.05). Compared to before treatment,inflammatory factors of 3 groups were decreased signifi-cantly after treatment,the ulinastatin group was significantly lower than the Xingnaojing group,combination group was signifi-cantly lower than two single drug groups,with statistical significance(P<0.05). Levels of serologic indexes of craniocerebral injury and GCS scores of 3 groups were improved significantly,and the combination group was significantly better than the two single drug groups,with statistical significance(P<0.05). There was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). Six months after treatment,GOS score of combination group(4.17±0.81)was significantly better than those of ulinastatin group(3.05±0.97)and Xing-naojing group(2.97 ± 0.89),with statistical significance (P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). During treatment,the incidence of ADR in combination group(27.50%)was significantly lower than ulinastatin group(50.00%)and Xingnaojing group(42.50%),with statistical significance(P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). CONCLUSIONS:Ulinastatin injection combined with Xingnaojing injection can sig-nificantly decrease serum inflammatory factor levels,relieve craniocerebral injury,protect cerebral tissue and improve short-term prognosis with good safety.

Objective:To investigate the clinical features of patients with maintenance hemodialysis (MHD) infected with SARS-CoV-2 and analyze the risk factors of death after SARS-CoV-2 infection, and to provide clinical data for early detection of critically ill patients and timely intervention.Methods:It was a cross-sectional investigation study. MHD patients in the hemodialysis centers of four tertiary hospitals with geographical representation in Shanxi province from December 1, 2022 to January 31, 2023 were enrolled, and the demographic data, dialysis-related indicators, laboratory test results and clinical features of SARS-CoV-2 infection were collected by distributing the questionnaires on SARS-CoV-2 infection, and consulting the hospital medical record system and the outpatient hemodialysis information system. SARS-CoV-2-infected patients were divided into survival group and death group according to whether all-cause death occurred and the differences of baseline data between the two groups were compared. Multivariate logistic regression analysis method was used to analyze the risk factors of mortality in MHD patients infected with SARS-CoV-2.Results:A total of 519 MHD patients were included in this study, with 508 patients (97.88%) infected with SARS-CoV-2, 474 patients in the survival group and 34 patients in the death group. The clinical symptoms of MHD patients infected with SARS-CoV-2 were diverse, and the most common initial symptom was fever (314/508, 61.81%). Other initial symptoms included cough and phlegm in 66 patients (12.99%), fatigue in 66 patients (12.99%), poor appetite in 20 patients (3.94%), dyspnea in 20 patients (3.94%), muscle pain in 14 patients (2.76%) and diarrhea in 8 patients (1.57%). Compared with the survival group, the death group had older age ( t=5.229, P<0.001), high proportions of males ( χ2=12.319, P<0.001) and diabetic nephropathy ( χ2=49.423, P<0.001), and lower levels of red blood cells ( t=-5.060, P<0.001), lymphocyte ( t=-2.614, P=0.011), neutrophil ( t=-5.117, P<0.001), serum albumin ( t=-2.940, P=0.012), serum prealbumin ( t=-3.519, P=0.001), blood phosphorus ( t=-3.309, P=0.002), serum creatinine ( Z=-3.607, P<0.001), total triglyceride ( Z=-2.486, P=0.013), total cholesterol ( Z=-3.291, P=0.001) and low-density lipoprotein cholesterol ( Z=-3.292, P=0.001). Among 508 SARS-CoV-2-infected patients, 194 patients (38.19%) were treated with nonsteroidal anti-inflammatory agents, 154 patients (30.31%) were treated with antibiotics, and 98 patients (19.29%) were treated with antiviral drugs. There were 225 (43.29%) vaccinated patients against SARS-CoV-2. Multivariate logistic regression analysis showed that low red blood cells ( OR=0.256, 95% CI 0.014-0.429), low lymphocytes ( OR=0.487, 95% CI 0.193-0.826), low serum albumin ( OR=0.613, 95% CI 0.329-0.917), older age ( OR=1.227, 95% CI 1.066-1.412) and diabetes mellitus ( OR=1.126, 95% CI 1.025-1.235) were the independent influencing factors of all-cause mortality in MHD patients infected with SARS-CoV-2. Conclusions:The clinical manifestations of SARS-CoV-2 infection in MHD patients are varied. Low red blood cells, low lymphocytes, low serum albumin, elder age and diabetes mellitus are the independent risk factors of death after SARS-CoV-2 infection in MHD patients. Strengthening management of MHD patients especially in the elderly, and improving and correcting anemia and malnutrition in time, may reduce the death risk of SARS-CoV-2 infection in MHD patients.
