AIM: To find a more efficient and accurate method for medical image enhancement to resolve the problem of low local contrast, which often appears in magnetic resonance (MR) images.METHODS: Based on the investigation into the previous methods, a new algorithm was presented. The main features were as follows: Non-dual was used in the morphological operations and addition instead of multiplication was used in the contrast stretching operations. To avoid some gray-level bias, the method of normalized gray-level under condition was proposed.RESULTS: The new algorithm was tested by real MR images and simulated experiments. Compared with the previous method, the new method is more accurate, faster and less sensitive to noise.CONCLUSION: Non-dual morphological operations can achieve local contrast enhancement in a more accurate way, and the gray level bias can be eliminated by normalization.

Objective To explore the effect of psychological counseling skills on medical treatment and satisfaction degree of patients in hospital.Methods Toally 60 discharged patients during December 2015 were assigned as the control group and another discharged one during January 2016 as the intervention group.Training on psychological counseling skills was done for the nurses by the psychological counselor in the intervention group while the control group was not.The two groups were compared on the basis of investigation with the patient's consultation experience scale as well as the medical satisfaction questionnaire.Result The satisfaction levels of consultation experience and medical consultation satisfaction in the intervention group were both higher than those of the control group (all P＜0.01).Conclusion Psychological counseling skills used in the nurse patient communication can enhance the patient's medical experience and their satisfaction with medical treatment.

Objective To investigate the complications of minimally invasive percutaneous nephrolithotomy (PCNL) and their countermeasures.Methods The datum of 265 cases who underwent PCNL in our hospital.Among the 265 cases of PCNL,serious complications occurred in 13 cases.Of the 13 cases,4 cases had massive hemorrhage,2 case had colon perforation,1 case had serious urinary extravasation,6 cases had febricity.Results The incidence of serious complications was 4.91％(13/265),all patients were cured by corresponding treatment and no death in the cases.Conclusions Adequate preoperative preparation in PCNL and strict surgical indications were good for complications reduction.Serious complications should be detected early and treated correspondingly.

Objective To investigate the effects of preoperative parecoxib on the levels of inter-leukin 6 (IL-6)and postoperative analgesia for breast surgery.Methods Sixty breast cancer patients undergoing mastectomy were randomly divided into two groups:parecoxib group (group P)and con-trol group (group C),n=30 in each group.All patients received sevoflurane and fentanyl anesthesia. Group P was injected parecoxib 40 mg at 10 minutes before induction of anesthesia,meanwhile group C was injected saline 5 ml.All patients received postoperative patient-controlled intravenous analgesia (PCIA)with fentanyl.VAS scores for pain were assessed at postoperative 2,4,8,12,24 hours. The serum levels of IL-6 were measured by ELISA at 10 minutes before induction,4 h,8 h,and 24 h after surgery.Results Group P had lower VAS scores than group C at 2-12 h after surgery (P <0.05).Compared with 10 minutes before induction,the levels of IL-6 increased significantly at post-operative 4,8,24 h in two groups (P<0.01),while group P had lower levels of IL-6 than group C (P <0.01).Conclusion Preoperative administration of parecoxib has a stronger analgesic effect in breast cancer patients after mastectomy,and decreases the levels of IL-6.

Objective Investigation of the Hexi Corridor in Gansu Province in the pathogenesis of esophageal cancer risk factors, prevention and treatment for esophageal cancer provide the basis. Methods Based on the hospital case control study, a survey of the region' s incidence of esophageal cancer risk factors. Results The single factor, multi factors and Logistic regression analysis found that Large quantities of alcohol, eating less fresh vegetables and less meat,eggs and fish, hot drink and diet, family history of esophageal cancer, history of significant mental trauma and low education level factors and esophagus cancer incidence closely related to the incidence of esophageal cancer in the Hexi Corridor is the main risk factors. At the same time, smoking, eating fast, eating sauerkraut was not related to the incidence of esophageal cancer. Conclusion After the investigation discovered this local esophagus cancer morbidity dangerous factor and locality special living conditions factor related, mainly displays in diet aspects and so on habits and customs and energetic factor. These factor function is by no means independent, but is affects mutually, affects mutually forms.

OBJECTIVE:To provide reference for the realization of normalization and standardization of quality control and management of Pharmacy intravenous admixture service(PIVAS). METHODS:The management and effectiveness of PIVAS quali-ty control in our hospital were introduced from aspects of the establishment of internal quality control system,the key indicators and effects of quality control. RESULTS:According to checking items from aspects of examining once in a month,on prescription checking,preparation,infection control,equipments,drugs,consumable materials,sanitation;holding 1 monthly quality control reviews;and analyzing unqualified indexes and existing security risks,the quality control of PIVAS had achieved good results. The qualified percentage of quality control index was increased from 84%(Jan. 2016)to 90%(Jun. 2016),error rate in the same peri-od was decreased from 0.579‰ to 0.099‰. CONCLUSIONS:Developing quality control of the implementation of detailed quality control key indexes for the whole process of intravenous infusion in PIVAS can effectively regulate the position working process,re-duce preparation error and ensure the quality of infusion preparation.

Objective To understand the e ff ectiveness of parasite ova sediment and non-hazardous treatment of two-grille la trines. Methods Two-grille latrines were recon n oitered in the field according to the non-hazardous treatment criteria, and th e sediment of parasite ova, the value of fecal coliform bacteria, NH 3-N, CODcr of the samples from the Grille 1 and Grille 2 of latrines were detected.Results The structure of some two-grille latrines was n o t in accord with the non-hazardous treatment criteria.Parasite ova were detecte d from the Grille 2 of one latrine. Six of 16 latrines were not eligible for non -ha zardous treatment according to the value of fecal coliform bacteria in Grille 2. Conclusion It is not suggested to popularize th e two-grille latrine yet, but it can be used as an interim form for excrement n on-hazardous treatment in rural areas. [

Objective: The aim of this study was to explore the correlation between the clinicopathological characteristics of colorectal adenocarcinoma and the growth pattern, tumor budding, and CD8+T lymphocyte infiltration in anterior invasive margins, and to assess their value as prognostic indicators. Methods: Paraffin embedded samples were collected from 126 patients with primary colorectal adenocarcinoma who underwent surgical resection in Zhangye People's Hospital Affiliated to Hexi College from January 2008 to December 2019. A total of 126 pathological sections were stained by immunohistochemistry. Anti-cytokeratin antibodies were used to mark tumor cell budding and anti-CD8 antibody markers T lymphocytes were evaluated. Results: In colorectal adenocarcinoma, infiltrative growth patterns and high-grade tumor budding in invasive margins were significantly associated with pathological stage of tumor size (pT) (P=0.029 and P<0.001, respectively), pathological stage of lymph node metastasis (pN) (P<0.001 and P=0.023, respectively) and vessel infiltration (P<0.001 and P<0.001, respectively). Furthermore, high-grade CD8+T lymphocyte infiltration was associated with the absence of lymph node metastases (P=0.050). Conclusions: Infiltrative growth patterns and high-grade tumor budding in colorectal adenocarcinoma invasive margins were correlated with patient prognosis. Importantly, these two features are easily detectable (with the help of pan-cytokeratin immunohistochemistry staining), in a reproducible manner. Therefore, we propose that they could be used as prognostic indicators in colorectal adenocarcinoma patients.

Objective To develop two-grille latrines with the effect of non-hazardous treatment. Methods According to the result of the pretest, one type of two-grille latrines was selected and constructed and its effect of non-hazardous treatment was evaluated. Results The faces-treatment pool, with cement-prefab structure and obturation, had a total cubage of 1.32 m3. The average total amount of faces in the pool was 1.05 m3 per family per month, and the pool could store the faces for over 34 days. The “reaching criteria rate” of the parasite ova sediment and the value of the fecal coliform bacteria were 100% among the excrement in the outlet. Conclusions The prefab two-grille latrines can reach the criteria of non-hazardous treatment, and they can be used in well-off rural areas without the usage of manure.
