Objective:To analyze the clinical characteristics of functional esophagogastric junction outflow obstruction (EGJOO) and to improve the knowledge of functional EGJOO.Methods:From January 2015 to December 2019, at the Gastrointestinal Motility Center of The First Affiliated Hospital with Nanjing Medical University, 91 patients who underwent high resolution esophageal manometry (HREM) and met the EGJOO criteria of Chicago Classification for esophageal motility disorders, 3rd edition and excluded organic diseases by examination such as gastroscopy or upper gastrointestinal radiography were collected. The clinical manifestations, treatment methods, effect and clinical outcome of patients with functional EGJOO, the HREM parameters of patients with different clinical manifestations as well as symptoms and HREM parameters of patients with different treatments were analyzed. Least significant difference test or Tamhanes T2 test, Mann-Whitney U or Wilcoxon test, chi-square test or Fisher exact test were used for statistical analysis. Results:The most common symptom of 91 functional EGJOO patients was dysphagia (34/91, 37.4%). The lower esophageal sphincter pressure (LESP) and the intrabolus pressure during relaxation of the lower esophageal sphincter (IBP LESR) of patients with dysphagia were both higher than those of patients without dysphagia (30.95 mmHg (26.27 mmHg, 39.37 mmHg) (1 mmHg=0.133 kPa) vs. 27.35 mmHg (24.60 mmHg, 34.87 mmHg); (8.25±4.64) mmHg vs. (5.69±4.65) mmHg), and the differences were statistically significant ( Z=2.076, t=2.539; P=0.038, 0.013). Thirty patients (33.0%) had no special treatment, 52 patients (57.1%) were treated with medication, and nine patients (10.0%) underwent peroral endoscopic myotomy (POEM). The incidence of dysphagia before treatment and maximum intrabolus pressure of patients who underwent POEM were both higher than those of patients without special treatment and medication treatment (8/9 vs 43.3%, 13/30 and 25.0%, 13/52; 21.80 mmHg (15.45 mmHg, 28.95 mmHg) vs. 12.20 mmHg (10.00 mmHg, 18.10 mmHg) and 13.70 mmHg (11.07 mmHg, 17.82 mmHg)), and the differences were statistically significant (Fisher exact test, Fisher exact test; Z=2.814, 2.390; P=0.023, P<0.01, P=0.005, 0.017). The incidences of delayed esophageal emptying or esophageal dilation of patients who underwent POEM, without special treatment and with medication treatment was 6/9, 5/14 and 3/18, respectively, and the differences were statistically significant among three groups (Fisher exact test, P=0.039). Among them, the incidence of delayed esophageal emptying or esophageal dilation of patients received POEM before treatment was higher than that of patients with medication treatment (Fisher exact test, P=0.026). The symptoms of 24.2% (22/91) was spontaneously relieved, and two patients (2.2%) developed type Ⅱ achalasia during follow-up. Conclusions:The main manifestation of patients with functional EGJOO is dysphagia. Patients with significantly increased LESP and IBP LESP are more likely to have dysphagia. Patients with obvious signs of esophageal gastric junction obstruction are more inclined to choose POEM treatment. Some patients with functional EGJOO can relieve themselves, and a few patients can develop achalasia.

OBJECTIVE To compare two different observed data from Nov 2003 to Apr 2004 and from Jan 2005 to Dec 2005 on hospital-acquired infection in our hospital and put forward the counterned measures.METHODS The bacteria samples from clinic were cultured.RESULTS The Pseudomonas aerugonosa,Acinetobacter baumannii and Escherichia coli were common strains of bacteria according to the two years data in our hospital.They were 30.35%,18.41% and 8.46% vs 19.74%,17.11% and 14.04%,respectively.The P.aerugonosa infective constituent ratio was decreased(30.35% vs 19.74%,P

Objective To observe the trend of temperature changes after ventriculoperitoneal shunt and its relation with postoperative infection.Methods A retrospective cohort study was conducted on 272 patients underwent ventriculoperitoneal shunt in our hospital from January 2015 to December 2018.Patients were divided into infected group and non-infected group according to whether intracranial infection occurred after surgery.According to the occurring time of postoperative intracranial infection,patients were divided into early infection group and delayed infection group.Temperature levels of all patients were monitored on the surgery day,and on the first,yd,5th and 7th d of surgery,and the temperature changes and fever rate of the two groups were compared.Results Among 272 patients,intracranial infection occurred in 25 (9.19％),including 21 with early infection and 4 with delayed infection,and un-infection in 247 (90.81％).As compared with those in the non-infected group,the fever rate and body temperature of the infected group were significantly higher on the 3rd,5th and 7th d after surgery (P＜0.05).There was no significant difference in fever rate and body temperature changes between the early infection group and the delayed infection group on the surgery day and on the first,3rd,5th and 7th d of surgery (P＞0.05).Conclusions The fever rate is higher and the body temperature decreases faster after ventriculoperitoneal shunt.The fever since the third d of surgery is closely related to postoperative intracranial infection,which has a certain predictive significance for postoperative infection,so we should consider anti-infection treatment in time.

Objective To explore the effect of propagating and educating (planning, doing, checking, and acting) circulation combined with neuronavigation system on improving surgical coordination at perioperative nursing in patients with pituitary tumors. Methods One hundred and sixteen patients with pituitary tumors, admitted to and accepted neuronavigation assisted microsurgery in our hospitals from August 2016 to August 2018, were chosen in our study; these patients were randomly divided into experimental group and control group (n=58). Patients from the control group accepted traditional perioperative propagating and educating circulation, while patients from the experimental group accepted perioperative propagating and educating (planning, doing, checking, and acting [PDCA]) circulation. Awareness rate of surgical preparation knowledge, self-rating anxiety scale (SAS) scores, degrees of operation coordination, length of hospital stays, hospitalization cost and postoperative complications were compared between the two groups. Results As compared with patients in the control group, patients in the experimental group had significantly higher knowledge of surgical preparation, statistically lower SAS scores and statistically lower proportion of patients with poor surgical coordination (P<0.05). As compared with those in the control group, the hospitalization cost, length of hospital stays and incidence of surgical complications (5.1％ vs. 12.1％) in the experimental group were statistically decreased (P<0.05). Conclusions PDCA circulation combined with neuronavigation system can be used as a kind of brand-new education mode for patients with pituitary adenomas. As compared with traditional perioperative mode, the new mode can significantly improve the awareness rate of surgical preparation knowledge, relieve anxiety level, improve cooperation degree, and reduce the postoperative complications, length of hospital stays, and hospital expenses, which means great clinical significance.

Objective To compare the Barcelona clinic liver cancer staging classification (BCLC), the Japan integrated staging score (JIS), the cancer of the liver Italian program score (CLIP) and Chinese staging system in terms of their ability to predict outcomes and to guide option of therapy in patients with hepatocellular carcinoma (HCC) in China.Methods Clinical data of 861 HCC patients from Zhongshan Hospital between 2001 and 2002 were retrospectively analyzed. Patients were classified acccording to different staging systems. Survival for patients in different stages and the effects of therapeutic methods on survival time were compared. Results BCLC, JIS and Chinese staging system showed the ability in predicting survival for patients in different staging. CLIP failed to show significant difference in survival rates for each subgroup. There was no significant difference in survival rate between surgery and transarterial chemoembolization (TACE)/transarterial embolization (TAE) for patients classified as BCLC stage C, CLIP scores more than 3 or Chinese stage Ⅲ a.The survival rate, however, was higher in patients received operation than those received TACE/TAE if they were classified as earlier stages. Conclusions The BCLC, JIS and Chinese staging systems show prospective ability for Chinese HCC patients in prediction outcomes, whereas the BCLC and the Chinese staging systems are better at both predicting outcomes and guiding the option of treatment.

Objective To explore the effectiveness of a myoelectricity-driven hand robot on the recovery of hand motor function early after a stroke.Methods Thirty stroke survivors were randomly assigned to either a control group (n=15) or an experimental group (n =15).Both groups received routine rehabilitation exercises,while the experimental group additionally received hand training using a robotic hand exoskeleton.Before and after 4 weeks of treatment,the motor function of the wrist and fingers in both groups were measured using the Fugl-Meyer assessment.Spasticity in the index,middle,ring and little fingers was quantified using the modified Ashworth scale.The muscle force of the fourth finger,thumb and all of the fingers during maximum voluntary extension and flexion were recorded using the robot's surface electromyography system.Results Significant increases in the average Fugl-Meyer scores in both groups were observed after 4 weeks of treatment,but the experimental group's average score was by then significantly higher than that of the control group.The experimental group's average Ashworth score and the average sEMG amplitudes were also significantly better than those of the control group.Conclusion Supplementing routine rehabilitation exercises with a hand robot can improve hand motor function and muscle force significantly,as well as relieving hand spasticity early after a stroke.

Objective To investigate the correlation between interleukin-6 (IL-6) and future liver remnant (FLR) growth after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 15 patients who underwent ALPPS at the First Affiliated Hospital of Guangxi Medical University between March 2017 and May 2018 were collected.Observation indicators:(1) intraoperative situations in the first staged ALPPS and the second staged ALPPS;(2) postoperative situations:① postoperative complications and duration of hospital stay,② results of pathological examination;(3) IL-6 concentration in the peripheral blood before and after operation;(4)follow-up situations.Follow-up using outpatient examination,telephone interview and internet was performed to detect life quality and survival of patients.Imaging examination was done to detect tumor recurrence and metastasis.Follow-up was done up to May 2018.Measurement data with normal distribution or similar normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (range).Repeated measures data were analyzed by the repeated measures ANOVA.Correlation comparison was done using Pearson bivariate correlation test.Results (1) Intraoperative situations.① The first staged ALPPS:15 patients had liver parenchymal transection via anterior approach combined with selective hepatic vascular exclusion,without allogenic blood transfusion.The operation time,volume of intraoperative blood loss,FLR at postoperative 16 days,interval time to the second staged ALPPS,growth rate of liver volume,ratio of FLR and standard liver volume (SLV) were respectively 324 minutes (range,240-387 minutes),356 mL (range,200-600 mL),(582± 134) cm3,24 days (range,9-34 days),35％±20％ and 53％±7％.② The second staged ALPPS:of 15 patients,13 underwent the second staged ALPPS successfully including 11 undergoing middle hepatic vein preserved right hepatectomy and 2 undergoing expanded right hemihepatectomy or right trisegmentectomy,1 underwent transcatheter arterial chemoembolization (TACE) due to FLR/SLV =31％,1 was detected yellow-white nodules at left lobe and confirmed as hepatocellular carcinoma by frozen section pathological examination,and then improved and discharged after 5-FU abdominal local chemotherapy combined with postoperative TACE.The operation time,volume of intraoperative blood loss of 13 patients undergoing the second staged ALPPS were 324 minutes (range,140-515 minutes) and 639 mL(range,100-1 400 mL).Two patients had blood transfusion including 1 with 800 mL of fresh frozen plasma and 4.0 U of red cells and 1 with 600 mL of plasma and 9.5 U of de-leucocytes and red cells.(2) Postoperative situations.① Postoperative complications and duration of hospital stay:15 patients had no perioperative death,9 and 6 were detected grade A and grade B liver failure respectively,15 had grade Ⅰ complications of Clavien-Dindo classification and no patient had grade Ⅱ and above complications,10 had pleural effusion including 1 with volume of effusion ＞500 mL.Of 13 patients undergoing the second staged ALPPS,4 and 9 were detected grade A and grade B liver failure respectively,8 and 5 had grade Ⅰ and Ⅱ complications of Clavien-Dindo classification and no patient had grade Ⅲ and above complications,11 had few pleural effusion with volume of effusion ＜500 mL.Patients with grade B liver failure and grade Ⅱ complications were recovered and discharged after treatments of liver protection,gastric protection,reinforced dressing change,continuous use of Alb,fresh frozen plasma transfusion.The patient with volume of pleural effusion ＞ 500 mL was improved after closed thoracic drainage and other patients with pleural effusion were improved after symptomatic and supportive treatment.Duration of total hospital stay was 31 days (range,22-49 days) in 15 patients.② Results of pathological examination:13 patients undergoing complete ALPPS were diagnosed as hepaticocellular carcinoma with R0 resection and without cancer cells involving surgical margin,including 7 with grade Ⅱ portal vein tumor thrombus.Ishak score for postoperative pathological fibrosis and liver cirrhosis was 7.7±1.4 in 15 patients,including 1 case of 5,1 case of 6,2 case of 7,6 case of 8,5 case of 9.(3) IL-6 concentration in the peripheral blood before and after operation:IL-6 concentration in the peripheral blood before surgery was (8±3)ng/L in 15 patients,and (207±150)ng/L,(104±65)ng/L,(45±38)ng/L,(26±9)ng/L,(18±10)ng/L at 1,3,5,7,10 days after the first staged ALPPS,showing a statistically significant difference in changing trend before and after surgery (F=25.877,P＜0.05) and statistically significant differences in paired comparison between 1,3,5,7,10 days after the first staged ALPPS and before surgery respectively (P＜0.05).There was correlation between IL-6 concentration in the peripheral blood at 1,3 days after the first staged ALPPS and growth of FLR (r=0.766,0.881,P＜0.05),and also between IL-6 concentration in the peripheral blood at 1,3 days after the first staged ALPPS and growth rate of FLR (r =0.810,0.879,P＜ 0.05).(4) Follow-up:15 patients were followed up for 1-14 months with a median time of 7 months.Of the 15 patients,1 without the second staged ALPPS died of multiple organ dysfunction syndrome at 7 months after the first staged ALPPS,14 survived and took care of theirselves in daily life during follow-up with improved life quality,including 1 detected multiple lung metastases at 12 months after complete ALPPS with mild increased AFP and 13 undetected new lesions in the remnant liver on contrast-enhanced CT and liver contrast-enhanced ultrasonography with normal AFP.Conclusion The peak of IL-6 concentration in peripheral blood at 1,3 days after the first staged ALPPS is significantly correlated with the hyperplasia of FLR,which may be used to predict the hyperplasia of FLR.

Objective:To observe the clinical characteristics of pressure regulation frequency of shunt pump in patients with hydrocephalus after ventriculoperitoneal shunt, and explore the correlation between frequencies of shunt pump and prognoses of these patients.Methods:One hundred and one patients underwent ventriculoperitoneal shunt in our hospital from January 2018 to December 2018 were selected. According to the frequencies of postoperative pressure regulation of these patients, they were divided into non-pressure regulation group, low-frequency pressure regulation group (1-2 times) and high-frequency pressure regulation group (2 times or more). The relations of high-pressure hydrocephalus/normal pressure hydrocephalus with pressure regulation frequency, and relation between causes of pressure regulation and pressure regulation frequency were compared, and the prognoses of patients with different pressure regulation frequencies were analyzed.Results:Among the 101 patients with implanted adjustable pressure shunt, 34 had no pressure regulation after surgery, 52 had low-frequency pressure regulation, and 15 had high-frequency pressure regulation. The percentages of patients accepted low-frequency pressure regulation and high-frequency pressure regulation in patients with high-pressure hydrocephalus were significantly higher than those with normal pressure hydrocephalus ( P<0.05). The proportions of patients with insufficient shunt, excessive shunt or magnetic field interference in the low-frequency pressure regulation group were significantly higher than those in the high-frequency pressure regulation group ( P<0.05), while the proportions of patients with abnormal shunt (stagger of insufficient shunt, excessive shunt) in the low-frequency pressure regulation group were significantly lower than those in the high-frequency pressure regulation group ( P<0.05). There were 7 patients with poor curative effect, including 4 patients from the low-frequency pressure regulation group and 3 from the high-frequency pressure regulation group. The prognoses of patients with different pressure regulation frequencies were statistically different( P<0.05), the good prognosis rate of patients in the non-pressure regulation group, low-frequency pressure regulation group and high-frequency pressure regulation group decreased successively. Conclusion:About 66.3% patients need pressure regulation treatment again after hydrocephalus-ventriculoperitoneal shunt; the rate of poor efficacy in patients accepted high-frequency pressure regulation is obviously higher than that in patients accepted low-frequency pressure regulation, which needs clinical attention.
