Objective To explore the clinical effects of laparoscopic combined with gastroscopic surgery for the gastric stromal tumors (GSTs) from the muscularis propria.Methods The clinical data of 25 patients with GSTs from the muscularis propria who were admitted to the Qianfoshan Hospital Affiliated to Shandong University between January 2011 and January 2014 were retrospectively analyzed.Patients received the general anaesthesia by endotracheal intubation.The pneumoperitoneum was done by an arc incision of 0.5 cm above margin of the umbilical cord and then laparoscopy was placed for exposing and gastroscopy was placed for confirming the location of the tumor.A laparoscope was placed in the cavity via the trocar at the navel,and the other two trocars penetrated both the abdominal and stomach walls.With gastroscopic monitoring,the operation was carried out in the gastric lumen using laparoscopic instruments and the tumor was resected.The tumor tissue was removed orally using a gastroscopic basket,and puncture holes and perforations were sutured using titanium clips.The proton pump inhibitor and antibiotics were used as the conventional therapy for 3 days,while adjuvant therapy with a usage of imatinib was applied to patients who were confirmed with the high-risk GSTs by pathological examination after tumors resection,and the other patients did not receive adjuvant therapy.Gastroscopic reexamination was done every 3 months within postoperative 1 year and then every 6 months after 1 year.Abdominal CT reexamination was done every 6 months within postoperative 1 year and then every 1 year after 1 year.The followup was done till December 2014.Results All the 25 patients received successfully modified laparoscopic combined with gastroscopic surgery without conversion to open surgery and postoperative complication.The operation time,volume of intraoperative blood loss,diameter of tumor,duration of postoperative abdominal pain and duration of hospital stay were (79 ± 4) minutes,(28 ± 3) mL,(2.6 ± 0.3) cm,(2.8 ± 0.3) days and (6.3 ± 0.3) days,respectively.GSTs were confirmed by postoperative pathological examination.The mitotic count was (3.3 ± 0.3) /50 HPF and reached R0 resection.Extremely low risk was detected in 3 patients,low risk in 19 patients,intermediate risk in 3 patients and no high risk was detected.Two of 3 patients with intermediate risk took the medicines following instructions without the adverse drug reaction,and 1 of 3 patients refused to take the medicines due to low income.All the patients were followed up for 12-36 months without the recurrence or metastasis of tumors.Conclusion Modified laparoscopic combined with gastroscopic surgery is feasible and effective for the treatment of gastric stromal tumors (GSTs) from the muscularis propria.

ObjectiveTo evaluate the quality of life and treatment of patients with primary biliary cholangitis (PBC) using the PBC-40 scale. MethodsThe PBC-40 scale was used to perform an investigation of 37 patients who were diagnosed with PBC and received continuous treatment in Department of Gastroenterology, The First Affiliated Hospital of Air Force Medical University, from January 2017 to December 2018. With reference to patients’ baseline biochemical parameters and pathological staging, the scores of the six domains of the PBC-40 scale, i.e., “symptom”, “pruritus”, “weakness”, “cognitive function”, “social function”, and “emotional function”, were analyzed. The two-independent-samples t test was used for comparison of normally distributed continuous data between two groups, and an analysis of variance was used for comparison between multiple groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The paired-samples Wilcoxon signed rank sum test was used for comparison of pruritus score before and after treatment, and the paired samples t-test was used for comparison of weakness score before and after treatment. A Spearman analysis was used to investigate correlation. ResultsIn the PBC-40 scale, the scores of symptom, pruritus, weakness, cognitive function, social function, and emotional function were 16.5±4.3, 5.2±3.3, 26.4±8.3, 15.3±5.1, 25.4±8.4, and 8.1±2.7, respectively. A stratified analysis was performed for the patients aged ＜50 years, 50-60 years, and ＞60 years, and the results showed that there was a significant difference in the score of pruritus between the different age groups (χ2=8.290, P=0.016). The PBC patients with a body mass index of ≥24 kg/m2 had significantly lower scores of symptom and cognitive function than those with a body mass index of ＜24 kg/m2 (symptom: Z=-2.222, P=0025; cognitive function: t=2.255, P=0.030). The patients with positive anticentromere antibody had a significantly higher score of weakness than those with negative anticentromere antibody (t=3.453, P=0.001). The score of pruritus was positively correlated with alkaline phosphatase (ALP) (R2=0.325, P=0.049) and gamma-glutamyl transpeptidase (GGT) (R2=0.402, P=0.014). ConclusionThe PBC-40 scale can be used to evaluate the quality of life of Chinese patients with PBC. High levels of ALP and GGT may predict low quality of life.

Objective:To explore the feasibility and safety of CT-guided hookwire localization of small lung nodule in video-as-sisted thoracic surgery. Methods: Preoperative localization of small lung nodule was performed using the CT-guided hookwire tech-nique, followed by video-assisted thoracic surgery in the wedge resection. The next mode of operation depends on the results of frozen biopsy. Results:Preoperative localization with CT-guided hookwire was performed in 34 patients between February 2012 and March 2014. The diameter of lung nodule ranged from 5 mm to 22 mm. CT-guided hookwire localization was successful in all patients, with a median positioning time of 23 min. Puncture needles were detached from two of the total patients during the surgery, and three other pa-tients showed pneumothorax by CT scan after localization. Conclusion:Preoperative hookwire localization of small lung nodule is an accurate and safe approach to improve the rate of wedge resection in video-assisted thoracic surgery.

Objective To explore the affect of acupuncture cooperating with Bobath approach on the spasticity after stroke.Methods 83 patient were divided into treatment group (42 cases) and control group (41 cases). On basis of conventional treatment, the treatment group accepted acupuncture and Bobath approach while the control group accepted a Bobath approach only. They were assessed with Modified Ashworth Scale before and 8 weeks after treatment. Results 8 weeks after treatment, the spasticity reduced in both groups, but more in the treatment group (P<0.05).Conclusion Acupuncture can facilitate the efficacy of Bobath approach on spasticity after stroke.

Objectives To conduct a research on the possibility and effect factors of latent fingerprints development in clothing objects after vacuum coating, and extracting fingerprints DNA and to probe in the relation among DNA template quantity and genetic loci numbers tested, and the rfu value after coating. Methods To select two groups that are free sweat hands and sweat hands and have them press their fingerprints on the cloth, after coating, and to analyze the effect of time, to quantify and test the targeted fingerprints DNA, to compare the locus numbers tested between white and black cloth. Results As the time is prolonged, the locus numbers tested decrease. The locus numbers tested on the group of sweat hands using the same method after the same placed time are lager than the free sweat hands. When the value of rfu is 600 above, the ratio of the locus numbers tested is more than 90% and the threshold of templates is 0.013ng. The locus numbers tested of white cloth is larger, comparing with black cloth when using the same method. What is more, there exists an prohibitive influence of pigments of the dyed cloth over the PCR amplification, to put it further, the loci numbers tested will be trimmed. Conclusion The technology of vacuum coating can be well used in the area of detecting fingerprint DNA.

Objective To evaluate the efficacy and safety of anticoagulant therapy with low-molecularweight heparin after cerebral hemorrhage combined with deep vein thrombosis of lower extremity.Methods One hundred and fifty-three cases of deep vein thrombosis of lower extremity after intracerebral hemorrhage were collected of Beijing Tiantan Hospital,Capital Medical University from June 2014 to June 2016.According to whether accepted anticoagulant therapy with low-molecular-weight heparin,the patients were divided into treatment group (n =79) and control group(n =74).Compared the head CT images and the ultrasound of lower extremity venous in the day when admissed to hospital and in the 7th day after treatment.The measurement data was adopted by t test,Chi-square test was adopted in the count data.Results Before the low-molecular-weight heparin therapy,the average bleeding volume in intracerebral was (1.38 ± 0.45) ml for the anticoagulant therapy group.After 7 days of low-molecular-weight heparin therapy,the average bleeding volune in intracerebral was (1.01 ± 0.54) ml,there was no increasing cerebral hemorrhage,with a statistically significant difference (P =0.000).The bleeding volume in intracerebral was(1.47 ± 0.47) ml of control group cases,and after 7 days it became (1.17 ± 0.52) ml,with a statistically significant difference (P =0.000),all these showed that cerebral hemorrhage had significantly absorbed.There was no statistically significant difference between the treatment group and the control group (P =0.123).It explained that anticoagulation was not increased intracranial hemorrhage with low-molecular-weight heparin.ultrasound showed that the lower extremity venous thrombosis was stable or decreased before and after anticoagulant therapy,and the difference was statistically significant (P =0.000),indicating that the anticoagulant therapy was effective.Conclusions It is safe and effective in low-molecular-weight heparin anticoagulant therapy for deep vein thrombosis of lower extremity after intracerebral hemorrhage.But patients need strict screening,and follow the individualized treatment.

Objective To study the causes of restenosis after endovascular treatment of long segment superficial femoral artery occlusion.Methods The clinical data of 38 patients with long segment superficial femoral artery occlusion were retrospectively analyzed,and the patients were treated with balloon dilatation and stent implantation.The patients were followed up 6 and 12 months after operation.The changes of claudication distance were observed,and the patients underwent color Doppler vascular ultrasound examination.The patients were divided into patency group and restenosis group according to the results of follow up, and the clinical data were compared between 2 groups.Results The follow-up result showed that patency was in 24 cases(patency group),and restenosis or occlusion was in 14 cases(restenosis group).The ankle brachial index(ABI)in restenosis group was significantly lower than that in patency group: 0.47 ± 0.41 vs.0.50 ± 0.48, and there was statistical difference (P<0.05).The data were classified according to the actual situation.Results showed that the lengths of occlusion segment >30cm, lengths of stent >30cm and age>70 years were the risk factors of restenosis after endovascular treatment in patients with long segment superficial femoral artery occlusion (P<0.05).Conclusions The endovascular treatment of long segment superficial femoral artery occlusion is safe and effective.The lower ABI,lengths of occlusion segment>30cm,lengths of stent>30cm and age>70 years are the risk factors of restenosis after endovascular treatment in patients with long segment superficial femoral artery occlusion.
