Chinese Journal of General Surgery 2017;32(7):553-556
Objective To evaluate the clinical characteristics,pathology,treatment and prognosis of gastrointestinal stromal tumors.Methods A retrospective analysis was made on clinical data of 469 patients with gastrointestinal stromal tumors (GIST) admitted between January 2010 and August 2016.Results There were 231 males and 238 females,the median age was 57 years old.The tumor was located in the esophagus in 6 cases (1.3%),in the stomach in 295 cases (62.9%),in the duodenum in 23 cases (4.9%),in the small intestine in 69 cases(14.7%),in the colorectum in 26 cases (5.5%).There were altogether 50 cases (10.6%) in this group with a final diagnosis of extra-gastrointestinal stromal tumors.Tumor invasion depth,risk of ulcer caused bleeding and NIH classification varied with its locations (all P < 0.05).Conclusions The clinical characteristics of gastrointestinal stromal tumors can be used to preliminarily predict its malignant degree.Surgical resection is the treatment of choice,and postoperative recurrence or metastases of gastrointestinal stromal tumors can be treated by imatinib.

Mixed saponin molecules in the extraction of Panax notoginseng(PNE) can be effectively desorpted into the molecular ionization for measurement and analysis by mass analyzer from matrix assisted laser desorption ionization-time of flight-mass spectrometry(MALDI-TOF MS). The saponin samples with chromatography purity were directly analyzed by MALDI-TOF MS, which indicated that the sensitivity of the method was higher than that of RP-HPLC. A technology of MALDI-TOF MS was directly employed to analyze the saponin kinds and their relative contents in Panax notoginseng(PN) while the saponins were perfectly extracted from the Chinese traditional medicine of PN. It was indicated that there were at least 20 saponins consisting of different molecular structure and that the content of both ginsenoside Rg1 and notoginsenoside R1 in PNE was relative high. R1 saponin was extracted and identified to follow its metabolism pathway by both thin layer chromatography and MALDI-TOF MS, respectively. The saponin fingerprinting maps in PNE can be established to evaluate the quality of PE and to study both metabolism pathway and mechanism of extra minim saponins in vivo.

Objective To discuss influence of early rehabilitation nursing on rehabilitation effect of patients after heart valve replacement.Methods 60 patients with heart valve replacement were divided into the rehabilitation group and the control group with 30 patients in each group.The control group was given normal nursing and self-exercise ad libitum.Based upon the above,the rehabilitation group was given systemic and normative rehabilitation nursing according to programs established for each individual.The incidence of complications,guardianship time and hospitalization time were compared between the two groups.Results The incidence of complications of the patients in the rehabilitation group was much lower than the patients in the control group.And the time of the patients in the rehabilitation group in ICU and hospitalization time was shorter than the patients in the control group.Conclusions Early rehabilitation care can effectively reduce the incidence of complications after cardiac surgery,promote recovery of cardiac function,also can improve the quality of life of patients.

Objective To develop infant thermal container with forced protection circuit so as to ensure its security. Methods Temperature database was set in thermal container and Cygnal F005 was used as intelligent controller. The state of the sensor was judged by comparison precisely. Double temperature controller was adopted to ensure normal working temperature. When the container went wrong, it could automatically switch to protection circuit to keep the temperature for infant. Results With precise temperature control and steady working station, the new type thermal container for infant could provide a safe and comfortable condition with clean air and fitting temperature and humidity. Conclusion The container is steady, accurate, safe and convenient.

Background Studies showed that inflammation is associated with the pathogenesis and development of dry eyes,and tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) are key inflammatory factors.Thymosin β4 (Tβ4) plays a promoting effect on the migration of epithelial cells and anti-inflammatory action.However,the influences of Tβ4 on the repair of ocular surface in dry eyes are unelucidated.Objective This study was to investigate the regulation of Tβ4 to the expressions of TNF-o and IFN-γand its effect on the recovery of ocular surface in rat dry eye models.Methods The dry eye models were induced by topically administered of benzalkonium chloride (BAC) for consecutive 7 days in the left eyes of 50 SPF male SD rats,and 36 successful models were used in the experiment.Tβ4 solution (9 μg/ml),recombinant human epithelial growth factor (rhEGF)and sterile PBS at 5 μl was topically administered three times for consecutive 7 days in the Tβ4 group,rhEGF group and PBS group,and no drug was used in the model control group.The normal right eyes of rats served as the normal control group.The break-up time of tear film (BUT),corneal fluorescein staining score and Schirmer Ⅰ test (S I t)were examined and evaluated in the rats on the seventh day after administration of drugs.Then the rats were sacrificed by excessive anesthesia and the sections of the ocular surface were prepared.The morphology of the specimens was examined by hematoxylin and eosin staining,and the number of conjunctival gobelt cells was counted by periodic acidschiff staining.The ultrastructure of the corneal and conjunctival cells was examined under the transmission electron microscope.The expressions of TNF-α mRNA and IFN-γ mRNA and their proteins in conjunctiva tissue were quantified by quantitative real-time PCR and Western blot,respectively.The use and care of the animals followed by Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The BUT was (10.42±0.66),(7.46±0.49),(8.71±0.50),(9.59±0.35) and (8.63± 0.68) seconds in the normal control group,model control group,rhEGF group,Tβ4 group and BUT group,showing a significant difference among the groups (F =5.65,P =0.00),and the BUT was evidently shortened in the model control group compared with the normal control group,while the BUT was significantly extended in the rhEGF group and Tβ4 group in comparison with the model control group (all at P<0.05).No significant differences were found in the corneal fluorescence score and S I t among the groups (F =0.42,P =0.79;F =136.77,P =0.00).The corneal and conjunctival epithelium defect and corneal stromal edema were seen in the model control group,and the proliferation of the epithelial cells were found in the rhEGF group and Tβ4 group,with the irregulated arrangement of the cells.A considerable difference was seen in the number of conjunetival goblet cells among the groups (F=3.16,P =0.04),and the number of eonjunctival goblet cells in the rhEGF group and model control group was significantly less than that in the normal control group (all at P<0.05),and no statistically significant difference was seen between Tβ4 group and normal control group (P > 0.05).The swelling,mergence,crispation,rupture and decrease of the microvilli and micro fold were found in the model control group,and the repair of the cell microvilli was seen in the Tβ4 group.The expressions of the TNF-α mRNA,IFN-γ mRNA and their proteins in the conjunctiva were significantly different among the groups (F =43.08,371.69,34.27,43.52,all at P =0.00),the expressions of the inflammatory factors were significantly higher in the model control group compared with the normal control group,and these expressions were evidently lower in the Tβ4 group in comparison with the model control group and rhEGF group (all at P<0.05).Conclusions The topical administration of Tβ4 solution can promote the repair of ocular surface by down-regulating the expression of TNF-α and IFN-γ in conjunctiva and stablize the tear film in rat dry eyes.

At present, the existing problem in nasal feeding perfusion apparatus is laborious and instability. Designing the rolling type perfusion apparatus by using a roller pump, the problem is solved. Compared with the traditional perfusion apparatus, the advantage lies in liquid carrying only need once and simulating human swallowing process. Through testing and verification, the apparatus can be used in nasal feeding perfusion for elderly or patients.
