Objective To investigate the relationship between the polymorphism of the tumor necrosis factor-αgene-308 promoter and bronchial asthma (BA)in Uighur and Kazakh population in Xinjiang.Methods PCR product sequencing method was used to detect the polymorphism distribution of TNF-αgene in 60 BA patients and 60 controls among Xinjiang Uighur and Kazakh population.Then we analyzed the association between different TNF-αgenotypes and BA in Uighur and Kazakh population.Results The distribution of GG,GA and AA genotype was significantly different between the two groups.Statistical analysis showed that BA group had a significantly higher TNF-αA allele frequency than that of the control one (P <0.05).After adjustment for sex and age,we found the A allele was a risk factor for BA pathogenesis (P <0.05).Conclusion The polymorphism of TNF-α gene-308 may be associated with the susceptibility to BA in Xinjiang Uighur and Kazakh population,so TNF-α gene-308 may be considered as a genetic marker for early identification of individuals at high risk for BA,which may play an important role in preventing the development of BA in clinical practice.

Objective:To study the effects of shenmai injection on postoperative delirium (POD) in patients undergoing off-pump coronary artery bypass graft (OPCABG).Methods:40 patients undergoing OPCABG from September 2019 to March 2020 in Linyi People's Hospital were randomly divided into (group S) and control group (group C), 20 cases in each group. Shenmai injection (0.6 ml/kg)was diluted to 150 ml with 5% glucose in group S, and pumped through the central vein at the beginning of the operation. In the group C, at the beginning of the operation, 5% glucose injection (150 ml) was pumped through central vein. The values of ejection fraction (EF), cardiac output (CO), stroke volume (SV), stroke volume variation (SVV), bispectral index (BIS), oxygen partial pressure (PO 2), central venous oxygen saturation (ScVO 2) and lactic acid (LAC) at anesthesia induction (T 0), at the beginning of operation (T 1), at the beginning of coronary artery bypass graft (T 2), at the end of coronary artery bypass graft (CABG) (T 3), and at the end of operation (T 4) were recorded. Patients were evaluated for delirium on the 3rd and 7th day after surgery. Results:The EF, CO in the patients of group C and group S at T 2 were found to be significantly lower than those at T 0 ( P<0.05). The ScVO 2, PO 2 in the patients of group C and group S at T 4 were found to be significantly lower than those at T 0 ( P<0.05). The EF, CO and SV in the patients of group S at T 3 to T 4 were found to be significantly higher than those in group C ( P<0.05). The incidence of postoperative delirium on the third day in the group S was significantly lower than that in the group C ( P<0.05). Conclusions:Shenmai injection can improve the cardiac function and reduce the incidence of POD in patients with OPCABG.

Objective To investigate the effects of hydrogen sulfide on autophagy and the apoptosis after acute spinal cord injury in rats. Methods Thirty-six adult male SD rats (250-300 g) were randomly divided into three groups (n=12 for each group):sham operation group (Sham group), spinal cord injury group (Model group) and hydrogen sulfide pre-treatment group (H2S group). Allen’s method was used to establish the rat model of spinal cord injury. Rats of sham operation group re?ceived only laminectomy. Rats of H2S group received sodium hydrosulphide injection intraperitoneally (50μmol/kg) 1h after spinal cord injury, and Model group was given the same amount of saline solution. Rats in the three groups were sacrificed 24 h after spinal cord injury, then the spinal cord was removed. The expressions of LC3, p70S6K and Cleaved caspase-3 were detected by Western blot assay. The expression of LC3 was also detected by immunofluorescence. The cell apoptosis was as?sessed by TUNEL stain. Results Compared with Sham group, the expression levels of LC3Ⅱ/LC3Ⅰand Cleaved caspase-3 were increased in Model group, but the expression of p70S6K decreased and cell apoptosis increased in Model group (P<0.01). Compared with Model group, the expression levels of LC3Ⅱ/LC3Ⅰand Cleaved caspase-3 were decreased significant?ly, while the expression of p70S6K increased and cell apoptosis decreased significantly in H2S group (P < 0.01). Conclu?sion Hydrogen sulfide can inhibit autophagy and reduce cell apoptosis after acute spinal cord injury in rats.

OBJECTIVETo discuss the impact of huolong moxibustion on pain degree in the patients of discogenic low back pain and the effect mechanism.

METHODSSixty-five patients were randomized into an observation group (33 cases) and a control group (32 cases). In the observation group, huolong moxibustion was applied along the distribution of the Governor Vessel, once a day. In the control group, the routine traction combined with massage therapy was adopted, once a day. In the two groups, the treatment was given 6 times a week, at interval of 1 day. In 3 weeks of treatment, pain score and serum tumor necrosis factor α (TNF-α) level were compared with those before treatment in the two groups.

RESULTSCompared with those before treatment, pain score and TNF-α level were reduced significantly after treatment in the two groups (both P < 0.05). The results in the observation group were lower than those in the control group (pain score: 1.95 ± 0.61 vs 2.11 ± 0.61; TNF-α: (1.33 ± 0.30) nmol/L vs (1.55 ± 0.48) nmol/L, (both P < 0.05).

CONCLUSIONHuolong moxibustion significantly alleviates pain in the patients of discogenic low back pain and its effect mechanism is possibly relevant with TNF-α reducing.

Objective To study the effect of Exendin-4 on oxidative stress and neural apoptosis following spinal cord injury (SCI). Methods Adult male SD rats, with weight between 200-250 g, were randomly divided into three groups (12 in each group):Sham group, SCI group and Exendin-4 group (Ex-4 group). Rats in Sham group achieved spinal cord exposure. SCI group and Ex-4 group were induced according to Allen′s test (using a weight-drop device). Rats in Ex-4 group were ad?ministrated with Exendin-4 (10 μg/rat) through intraperitoneal injection immediately after establishment of SCI models. Rats in Sham group and SCI group were given the same volume of normal saline solution instead. Level of malondialdehyde (MDA) and the activity of catalase (CAT) were assessed in spinal cord tissues 24 hour after drug administrations. Neural apoptosis was detected by TUNEL staining and the expression levels of caspase-9 and AIF were determined using Western blot. Results Compared with Sham group, the levels of MDA, caspase-9 and AIF as well as neuronal apoptosis rate in?creased obviously, while activity of CAT decreased markedly in SCI group(P<0.01). Compared with SCI group, the levels of MDA, caspase-9 and AIF as well as the neuronal apoptosis rate decreased obviously, while activity of CAT increased re?markably in Exendin-4 group(P < 0.01). Conclusion Exendin-4 restrain neural apoptosis following spinal cord injury through relieving oxidative damage.

Objective To study the significance of No12 lymphadenectomy in patients of advanced distal gastric cancer undergoing D2 distal or total gastrectomy.Methods Clinical and pathological data of 193 distal gastric cancer cases undergoing D2 gastrectomy and No12 lymphadenectomy during Jan 2012 and Jan 2013 were analyzed retrospectively.Results In Borrmann Ⅲ,Ⅳ No.12a LN metastasis was significantly higher than that in Borrmann Ⅰ,Ⅱ (x2 =4.841,P =0.028).In cases of multiple cancer 12a LN metastasis was significantly higher than that in gastric angle,gastric antrum (11.1％ 、9.7％ 、30.4％).High-differentiated cancer was lower in LN metastasis than that of low differentiated both in No.12a group (x2 =4.292,P =0.038),and in No.12b group (x2 =4.079,P =0.043).In cases with serosal invasion LN metastasis was higher than that without infiltration both in No.12a group (x2 =8.107,P =0.004),and in 12b group (x2 =3.836,P =0.050).In cases of N 0 ～ 1 the LN metastasis was lower than that in N 2 ～ 3 in 12a group (x2 =10.960,P=0.001),12b group (x2 =4.989,P =0.026),and in 12p group (x2 =4.433,P =0.035 respectively).In cases of tumor diameter ＜3 cm,3 ～5 cm and ＞5 cm,the 12a lymph node metastasis rate was 4.2％,10.0％,and 29.2％,respectively.Tumor size ＞ 5 cm has higher metastasis rate in No.12a group (x2 =6.464,P =0.011).Conclusions No.12 lymphadenectomy should be included routinely in D2 gastrectomy in patients of distal gastric carcinoma.

Objective To investigate the protective effect of Ebselen on mitochondrial damage and its influence to Cytochrome C expression and the neuronal apoptosis after spinal cord injury in rats. Methods Sixty adult SD rats were ran-domly divided into 5 groups (12 each group). Spinal cord injury model was made using Allen's method. Sham operation group received only laminectomy;SCI group received laminectomy and spinal trauma;Saline group received saline injection intraperitoneally (0.1%DMSO) after injury;methylprednisolone group received 30 mg/kg methylprednisolone injection intra-peritoneally, ebselen group received 10 mg/kg ebselen injection intraperitoneally. The malonaldehyde (MDA) and glutathi-one (GSH)level at the injured sites of the spinal cord were detected 24 hours after trauma, and the expression level of Cyto-chrome C was also observed. Finally, neuronal apoptosis was identified by TUNEL staining. Results MDA level in the Eb-selen group was significantly lower than that in the SCI group, and GSH level was significantly elevated in the Ebselen group compared with SCI group (P<0.01). Expression of Cytochrome C in Ebselen group was lower than that in SCI group shown by Western blot, and the neuronal apoptosis in Ebselen group reduced significantly too compared with SCI group (P<0.01). Conclusion Ebselen can alleviate peroxidation,prohibit expression of Cytochrome C and inhibit neuronal apoptosis,thus it shows a protective effect to experimental acute SCI.

Objective:To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty.Methods:From April to September 2016,patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed,and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery.Numeric pain rating scales (NPRS)pain scores in rest and activity 2,6,12,24 and 48 h after surgery were collected,and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed.Opioids consumption and anesthesia related adverse effects were also recorded.Results:In the study,40 patients were enrolled,with 20 patients in each group,male ∶female =7 ∶ 33,the age:(63.8 ± 10.1) years,and the body mass index (BMI):(28.5 ± 3.5) kg/ m2.The general conditions were comparable between the two groups.Though the rest pain 2 h after surgery [ACB =0.0(0,6),FNB =3.0(0,5),P=0.004] and activity pain 12 h post operation [ACB =3.0(3,0),FNB =5.5(0,10),P =0.004] were lower in ACB group compared with FNB group,there was no statistical difference in the other pain checking points between the two groups.The quadriceps strength 24 h and 48 h after surgery were (85.3-± 27.6) N and (80.0 ± 30.1) N in ACB group,(69.0 ± 29.4) N and (64.4 ± 32.0) N in FNB group,both of them were declined by time.The exact data were higher in ACB group,however,there was no statistical difference between the two group by repeated measurements variance analysis(F =2.703,P =0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h.And among them,three patients acquired once dolantin in ACB,two in FNB,from 24 to 48 h postoperation.There were five patients who suffered nausea postoperation in ACB group,and one who reported xerostomia.Four patients in FNB had nausea with vomiting,and three experienced xerostomia.Deep vein thrombosis appeared in 2 patients in FNB group,but no one in ACB group.Conclusion:Continuous ACB is not superior in pain control after TKA compared with FNB,and the quadriceps strength could be reserved more by this method,which performed early benefits in fast rehabilitation.

Objective To investigate the effects of edaravone (EDA) on cell apoptosis induced by endoplasmic reticu?lum stress (ESR) after spinal cord injury (SCI) in rats. Methods Thirty-six healthy adult SD rats were randomly divided in?to three groups (12 rats for each group):Sham group, SCI group and EDA group. The rat model of SCI was made by Allen’s method and the sham group was only received laminectomy and kept the spinal cord intact. Rats in sham group and SCI group accepted the same volume and frequency of saline injection as EDA group. The EDA group was given 10 mg/kg EDA once every 12 h intraperitoneally. Three days after injuring, the spinal cords were harvested, and the protein levels of C/EBP homologous protein (CHOP), Cleaved caspase-12 and Cleaved caspase-3 were detected by Western blot assay. Immunofluo?rescence staining was used to analyze the positive ratio of caspase-12 and CHOP in spinal cord of three groups. Meanwhile, TUNEL staining was used to identify cell apoptosis of spinal cord. Results Compared with sham group, the protein levels of CHOP, Cleaved caspase-12 and Cleaved caspase-3 were obviously higher in SCI group (P<0.01);the proportion of Cas?pase-12 and CHOP positive cells was significantly increased (P<0.01), and the apoptotic rates were also significantly in?creased in spinal cord (P<0.01). However, compared with SCI group, the protein levels of CHOP , Cleaved caspase-12 and Cleaved caspase-3 were significantly decreased in EDA group (P<0.01);the proportion of Caspase-12 and CHOP positive cells was significantly reduced (P<0.01), and the apoptotic rates were also significantly decreased in spinal cord (P<0.01). Conclusion EDA has neuroprotective potential to spinal cord injury. The mechanism of its neuroprotective effect may asso?ciate with its inhibitory effect to the cell apoptosis induced by endoplasmic reticulum stress after SCI.

Objective To explore the treatment experience of acute paraquat poisoning,thus to explore the prognostic factors and treatment measures.Methods The clinical data of 87 patients with paraquat poisoning who were treated with combined therapy in our hospital emergency department 2014-2015 were retrospectively analyzed.Results 49 cases survived and 38 cases were died in 87 paraquat poisoning patients,the survival rate was 56.32％.The average paraquat of the death group was 65.3mL,which was significantly higher than 41.2mL of the survival group(t =16.65,P ＜ 0.01).Conclusion Amount of poisoning is the key to the prognosis,white blood cells were significantly increased,early or large areas of lung disease is an important factor in poor prognosis;early gastric lavage,cathartic and timely blood purification,application of adrenal cortex hormones,antioxidant and other comprehensive treatment can reduce mortality.
