Objective To compare the effects of Ephedrine and combined with small dose cisatracurium treatments on the onset time of cisatracurium and hemodynamics in elderly patients.Methods Sixty cases of elderly patients undergoing elective surgery under general anesthesia were randomly divided into 4 groups:E group (ephedrine pretreatment),P group (cisatracurium primin),PE group (cisatracurium priming and ephedrine pretreatment) and C group(control),and each group of 15 cases.Cisatracurium 0.15 mg/kg were given in P group and PE group,and then ephedrine 70 μg/kg were given in PE group and E group.Anesthesia was induced with target controlled infusion of propofol (target plasma concentration 3-5 pg/ml),fentanyl 3-4 pg/kg.Cisatracurium 0.015 mg/kg were given in E group and C group,and P group and PE group dose intravenous cannula remaining.Tracheal intubation was performed when the twitch height depressed to 0.Results The Onset time of PE,C,E and P group were (164±28) s,(306±61) s,(187±31) s and (193±40) s and there were significant differences(F=33.990,P＜0.01).The onset time of PE group was shorter than that in C,E,P group,and the difference was significant (P＜0.05).Systolic pressure (SBP) and mean arterial pressure (MAP) levels in four groups after induction were lower than those before induction (F =35.783,30.015,P =0.000).SBP,diastolic blood pressure (DBP),MAP in PE group and E group were significant higher than those in C group(P＜0.05).After inductions,heart rate(HR) in PE group was significant different form that in C group(P ＜0.05),and HR of C group was significantly decrease than before inductions(P＜0.05).After inductions,the cases with DBP were 11 patients(73.3％) in C group,10 patients(66.7％) in P group:,5 patients(33.3％) in E group,and 4 patients (26.7％) in PE group,the different were significant (x2 =9.867,P ＜ 0.05).After intubation,cases with increase blood press were 3 patients (20.0％) in C group,5 patients(33.3％) in E group,and 4 patients(26.7％) in E group and PE group(P＞0.05).Conclusion Ephedrine of 70 μg/kg can relief the circulatory depression and accelerate the onset time of cisatracurium in the elderly patients.Combined with cisatracurium priming can further shorten the onset time and be for elders.

Objective:To investigate the short-term therapeutic effect and long-term survival of multiple myeloma patients with extramedullary disease (EMD) in the new drug era.Methods:The data of 74 patients with multiple myeloma diagnosed and treated in Anhui Wanbei Coal and Electricity Group General Hospital from January 2015 to January 2020 were retrospectively analyzed, including 17 patients with soft tissue infiltration (EM-S), 9 patients with bone infiltration (EM-B), and 48 patients without EMD (No-EMD). The short-term efficacy, the 4-year progression-free survival (PFS) rate and overall survival (OS) rate, and their influencing factors in three groups of patients after receiving bortezomib regimen were analyzed.Results:After 3-4 courses of early induction therapy of bortezomib regimen, the overall response rate of patients in the EM-S group was lower than that in the No-EMD group and the EM-B group [58.8% (10/17) vs. 85.4% (41/48), 100.0% (9/9)], and the differences were statistically significant ( χ2 = 13.7, P = 0.036; χ2 = 26.5, P = 0.003), while the difference between No-EMD group and EM-B group was not statistically significant ( χ2 = 12.7, P = 0.211). Survival analysis showed that the 4-year PFS rate of No-EMD group was higher than that of the EM-S group and EM-B group (41.0% vs. 7.6%, 0), and the differences were statistically significant ( χ2 = 10.835, P < 0.01; χ2 = 8.276, P = 0.004). Meanwhile, the 4-year OS rate of EM-S group was lower than that of the No-EMD group and EM-B group (16.5% vs. 54.3%, 59.3%), and the differences were statistically significant ( χ2 = 9.146, P = 0.002; χ2 = 4.066, P = 0.044). Conclusion:The early treatment effect of bortezomib regimen, PFS and OS in multiple myeloma patients with EM-S are poor, while the EM-B has no effect on OS.

Objective To study the ultrasonographic features and differential diagnosis of fetal penoscrotal transposition.Two dimensional and three dimensional ultrasound were applied in the diagnosis of fetal penoscrotal transpositionto improve the detection rate. Methods Twenty cases of suspected penile scrotal transposition of the fetus in Shengjing Hospital affiliated to China Medical University fromJanuary 2015 to February 2017were included in present study. The ultrasound findings, fetal chromosome examination and clinical follow-up outcome were retrospectively summarized. Results Among the 20 suspected cases of penile scrotal transposition, 17 cases were diagnosed correctly. All the 17 cases were partial type of penile scrotal transposition. In the remaining 3 cases, 2 caseswere hermaphroditism with the karyotype of 46-XX, and the other 1 case was confirmed as normal female fetusesby clinical follow-up after birth. The ″tulip″signwas the typical ultrasonographic features offetal penoscrotal transposition. Conclusion 2D combined with 3D ultraosound is useful in diagnosis and differential diagnosis of fetal penile scrotal transposition.

OBJECTIVETo assess the association of neural precursor cell expressed developmentally down-regulated 4 (NEDD4) with schizophrenia.

METHODSFive single nucleotide polymorphisms (SNPs) of the NEDD4 gene were genotyped by TaqMan SNP genotyping assay in an independent sample of 464 individuals with schizophrenia and 487 healthy controls from eastern Han Chinese population. Clinical data were collected with a general information questionnaire and Positive and Negative Syndrome Scale (PANSS).

RESULTSFrequencies of rs3088077 (allelic: χ2=18.024, P=0.000; genotypic: χ2=16.634, P=0.000), rs7162435 (allelic: χ2=6.771, P=0.009; genotypic: χ2=7.352, P=0.025) and rs2303579 (allelic: χ2=11.253, P=0.001; genotypic: χ2=12.248, P=0.002) were found to be significant different between the two groups. Moreover, TT of rs7162435 was significantly correlated with scores of factors of excitement and hostility (14.53±3.925, F=3.551, P=0.029).

CONCLUSIONrs3088077, rs7162435 and rs2303579 of the NEDD4 gene may be associated with schizophrenia. Moreover, the TT genotype of rs7162435 may increase the severity of excitement and hostility. Our results may provide a clue for delineating the connection between the glutamate hypothesis of schizophrenia and ubiquitination.

BACKGROUND/AIMS: Gastrointestinal (GI) symptoms may develop when we fail to adapt to various stressors of our daily life. Central oxytocin (OXT) can counteract the biological actions of corticotropin-releasing factor (CRF), and in turn attenuates stress responses. Administration (intracerebroventricular) of OXT significantly antagonized the inhibitory effects of chronic complicated stress (CCS) on GI dysmotility in rats. However, intracerebroventricular administration is an invasive pathway. Intranasal administration can rapidly deliver peptides to the brain avoiding stress response. The effects of intranasal OXT on hypothalamus-pituitary-adrenal axis and GI motility in CCS conditions have not been investigated. METHODS: A CCS rat model was set up, OXT 5, 10, or 20 μg were intranasal administered, 30 minutes prior to stress loading. Central CRF and OXT expression levels were analyzed, serum corticosterone and OXT concentrations were measured, and gastric and colonic motor functions were evaluated by gastric emptying, fecal pellet output, and motility recording system. RESULTS: Rats in CCS condition showed significantly increased CRF expression and corticosterone concentration, which resulted in delayed gastric emptying and increased fecal pellet output, attenuated gastric motility and enhanced colonic motility were also recorded. OXT 10 μg or 20 μg significantly reduced CRF mRNA expression and the corticosterone concentration, OXT 20 μg also helped to restore GI motor dysfunction induced by CCS. CONCLUSION: Intranasal administration of OXT has an anxiolytic effect and attenuates the hypothalamus-pituitary-adrenal axis in response to CCS, and gave effects which helped to restore GI dysmotility, and might be a new approach for the treatment of stress-induced GI motility disorders.

Objective:To investigate the expression level of TRPM7 in breast cancer tissues and adjacent carcinoma tissues and to analyze its clinicalpathological characteristics.Methods:The expressions of TRPM7 in 87 breast cancer and 47 adjacent tissues were detected by immunohistochemistry, and then the relationship between expression and clinicopathological characteristics was analyzed.Results:The positive rate of TRPM7 in breast cancer tissues was 66.7%, significantly higher than that in para-cancer tissues (10.6%) ( P<0.001) . Meanwhile, TRPM7 expression was much higher in those with tumor diameter≥2 cm ( P=0.023) , TNM stage III ( P=0.001) and lymph node metastasis ( P=0.015) . The expression of TRPM7 has nothing to do with patients’ age ( P=0.455) or histological grade ( P=0.577) . Conclusions:High expression of TRPM7 is associated with the development of breast cancer. TRPM7 may become a potential biological indicator to monitor the prognosis of breast cancer in the future.

OBJECTIVETo evaluate the feasibility and efficacy of Zhu's trocar placement (ZTP) in laparoscopic appendectomy (LA) in the treatment of complicated appendicitis.

METHODSClinical data of 139 complicated appendicitis patients undergoing LA at the First Affiliated Hospital of Wenzhou Medical University from June 2013 to December 2017 were retrospectively analyzed. ZTP-LA group comprised 59 cases and its procedure was as follows: 10 mm umbilical trocar was used as lens port; 12 mm trocar at crossing point of umbilical hole horizontal line and right midclavicular line was used as main operating port; 5 mm trocar at the crossing point of horizontal line 0-3 cm below umbilicus and right anterior axillary line was used as assist operating port with the drainage function for Douglas fossa and right iliac fossa; The operator and the assistant stood on the right side and the left side of the patient respectively. Traditional three-port group comprised 80 cases (8 cases converted to laparotomy, 72 cases enrolled finally) and its procedure was as follows: 10 mm lens port below umbilicus; 10-12 mm main operating port at lateral border of left lower rectus abdominis; 5 mm assist operating port above pubis; The operator and the assistant stood on left side of the patient. The operative time, time to oral semi-fluid, postoperative hospital stay, cost during hospitalization, and postoperative morbidity of complication were compared between two groups.

RESULTSBaseline data such as gender, age, WBC count, percentage of leukocyte, pathological finding and type were not significantly different between two groups(all P>0.05). The conversion rate in ZTP-LA was significantly lower than that in traditional three-port group [0%(0/59) vs. 10.0%(8/80),χ²=4.552,P=0.033]. Compared with traditional three-port group, ZTP-LA group showed shorter operative time [(47.8±20.1) minutes vs. (66.0±27.3) minutes, t=4.383,P<0.001], shorter time to oral semi-fluid [(35.0±20.7) hours vs. (59.3±32.8) hours, t=5.158,P<0.001], shorter postoperative hospital stay [(4.1±1.6) days vs. (5.5±2.2) days, t=4.162, P<0.001], lower postoperative morbidity of complication [3.4% (2/59) vs. 18.1%(13/72), χ²=6.879, P=0.009], lower incidence of postoperative intra-abdominal abscess [0%(0/59) vs. 11.1%(8/72), χ²=5.179, P=0.023], lower incidence of paralytic ileus [1.7%(1/59) vs. 12.5%(9/72), χ²=3.946, P=0.047] and less cost during hospitalization[(13 585±2909) yuan vs.(16 861±5334) yuan, t=4.463, P<0.001].

CONCLUSIONZTP-LA is safe, feasible and effective with advantages of faster recovery and less cost in the treatment of complicated appendicitis.
