BACKGROUND:In recent years, minimal y invasive percutaneous plate fixation has been a selectable method to repair fracture of lower limbs, especial y complex fracture of lower limbs. Its advantages are to reduce the damage to soft tissues, and do not destroy bone nutrient supply vessels. However, there is no unified criterion to select which method in the repair of distal tibial fractures. OBJECTIVE:To observe clinical effects of minimal y invasive percutaneous plate fixation versus open reduction and plate fixation in the repair of distal tibial fractures. METHODS:A total of 60 cases of distal tibial fractures treated with minimal y invasive percutaneous plate osteosynthesis (n=35) and open reduction and plate fixation (n=25) were selected. The time of surgery was identified by evaluating soft tissue. We should pay attention to the protection of soft tissue in surgery and reasonable fixation method should be selected. After fixation, we guided patients to do active early functional exercise. They were fol owed up and regularly received X-ray reexamination. Operation time, weight loading time, healing time and functional recovery were observed and the clinical therapeutic effects of the two methods were compared. RESULTS AND CONCLUSION:Al patients were fol owed-up after surgery. They were fol owed up for 3 to 15 months. No significant difference in healing time of type A fracture was detected between minimal y invasive percutaneous plate fixation and open reduction and plate fixation. The healing time of types B and C fracture was better in minimal y invasive percutaneous plate fixation group than in open reduction and plate fixation group. These results indicated that minimal y invasive percutaneous plate fixation in repair of tibial fractures, especial y distal complex tibial fractures, is an effective method. The healing rate of fracture was high, but postoperative complications were less.

Objective:To know the situation of continuing education for the hospital pharmacists in partial medical institutions of Guizhou province. Methods:An acquired questionnaire was designed and the investigation on partial hospital pharmacists in 91 medi-cal institutions was obtained, the times of participating in different medical conferences and continuing education programs in a year were recorded, and the interested continuing education programs were analyzed. Results:Totally 121 copies of questionnaires showed that 85. 95% hospital pharmacists had less than 5 times of participating in different kinds of medical conferences in a year, and less than 5 continuing education programs were held in 76. 03% medical institutions. The continuing education programs pharmacists inter-ested in were clinical pharmacy, clinical pharmacist training, pharmaceutical affairs management, basic knowledge, technology and practice training, and at the same time, 60 copies of questionnaire showed that there was a clinical pharmacist training plan in their hospital. Conclusion:The level of continuing education for the hospital pharmacists in Guizhou province is still low, and further edu-cation chances for the pharmacists are lacking. Therefore, it is necessary to increase the continuing education chances for the hospital pharmacists in Guizhou province and enhance the education level in order to improve the level of pharmaceutical care.

OBJECTIVETo explore the effect of Qingyi Granule (QYG) on high mobility group box-1 (HMGB1) expressions in liver and renal tissues of severe acute pancreatitis (SAP) rats.

METHODSFifty-four Sprague-Dawley (SD) rats were divided into the sham-operation (SO) group, the SAP group, and the QYG group according to random digits table. Rats in the SAP group were induced by injecting 5% sodium taurocholate (STC). Liver and renal pathological changes were observed by HE staining. Serum contents of amylase (AMS), MDA, IL-1, and HMGB1 were detected by ELISA. HMGB1 protein expressions in liver and renal tissues were tested by immunohistochemistry. HMGB1 mRNA expressions in liver and renal tissues were detected by reversed transcription PCR.

RESULTSThe pathological scores, serum levels of AMS, MDA, IL-1 and HMGB1, and protein and mRNA HMGB1 expressions in liver and renal tissues were increased more obviously in the SAP group than in the SO group (P < 0.05, P < 0.01). All of them could be down-regulated by QYG intervention, with the most significant effect seen at 72 h (P < 0.05, P < 0.01) in a time-effect relationship.

CONCLUSIONSHMGB1 participated in SAP complicated liver and renal injuries. QYG could effectively inhibit HMGB1 expressions, thereby attenuating SAP complicated liver and renal injuries.

Objective To compare the MRI features of hepatic neuroendocrine tumors (NET G1,G2) and neuroendocrine carcinomas (NEC G3),as well as to improve the accuracy in hierarchical diagnosis.Methods Twenty patients with histopathologically proven NET and nineteen patients with histopathologically proven NEC were retrospectively analyzed.The morphological and MR signal features were compared.Results The morphological features of vascular invasion (P ＜ 0.05) and lymphadenectasis or necrosis (P ＜ 0.05),as well as the MR signal features on portal phase (P ＜ 0.05) and delayed phase (P ＜0.05) were different between the NET group and the NEC group;contrast to noise ratios (CNR) were also different between the two groups (x2 =5.14,P ＜ 0.05),CNR of the NEC group on both arterial phase (Z =121.75,P ＜ 0.05) and portal phase (Z =139.31,P ＜ 0.05) were significantly lower than the NET group;ROC analysis of CNR demonstrated an area under the curve of 0.729 (P ＜ 0.05) on portal phase,when the optimal cut-off value of-61.38 was used,a sensitivity of 90.0％ and a specificity of 63.2％ can be achieved.Conclusions MRI plays an important role in the hierarchical diagnosis of hepatic neuroendocrine neoplasms.The signs of vascular invasion,lymphadenectasis or necrosis as well as the MR signal features during dynamic enhanced scanning are of great value in differentiating NETs from NECs.

Chronic pancreatitis (CP) is a kind of disease with the sustainable and irreversible damage of the tissue structure and function of pancreas,which may be caused by alcohol,gene,gallstone,metabolism,deformity and other factors.The clinical manifestations are intractable abdominal pain and disorder of the internal and external secretion of pancreas.At present,the main purpose of the treatment for chronic pancreatitis is to relieve patients' pain,and to maintain the secretion function of pancreas as far as possible.The main surgical procedures for chronic pancreatitis includes the pancreatic resection,nerve block and decompression drainage of the pancreatic duct.In recent years,people hve paid more attenntion to the whole pancreas resection combined autologous transplantation due to retaining some functions of the islet cells.After whole pancreas resection combined autologous transplantation,the abdominal pain will relieve and the life quality will improved significantly.At the same time,it will effectively reduce the occurrence of pancretogenic diabetes since the surgery retains some function of the islet cells.

Objective:To study the expression of miRNA-7 in B lymphocytes of primary Sj?gren's syndrome (pSS) and its relationship with phosphatase andtensin homolog deleted (PETN) and disease activity.Methods:Twenty newly diagnosed outpatient and inpatient pSS patients were used as case group collected from January 2017 to December 2019 of Qinghai Provincial People's Hospital. Twentyhealthy persons were used as the control group. Disease-related indicators of the case group were collected. Quantitative polymerase chain reaction (RT-qPCR)was used to detect miRNA-7 and PETN mRNA expression in B lymphocytes of the two groups and the consistency between miRNA-7 expression in the plasma and B lymphocytes of the case group was analyzed. Western Blotting method was used to detect the PETN protein in B lymphocytes of the two groups. Correlation analysis was used to analyze the relationship between miRNA-7 expression in B lymphocytes and disease activity in the case group. Linear regression analysis was performed between miRNA-7 and PETN mRNA.Results:The expression of miRNA-7 (0.53±0.17) in the B cells increased and the expression of PTEN mRNA (0.88± 0.24) and protein (0.51±0.12) in the case group were reduced compared with that of miRNA-7(0.39±0.11), PTEN mRNA(2.32±0.30) and protein(1.03±0.21) of the control group. The above differences were statistically significant ( t=2.990, P<0.05; t=16.98, P<0.05; t=8.41, P<0.05). Linear regression showedthat PTEN miRNAwas negatively correlated with miRNA-7 ( b=-0.78, P<0.01), the expression of miRNA-7 in the case group was positively related with EULAR Sj?gren′s syndrome Disease Activity Index (ESSDAI), IgG, IgA, anti-SSB and was negatively correlated with C4 and WBC. Conclusion:There is a certain relationship between miRNA-7 and disease activity. MiRNA-7 may participate in the pathogenesis of pSS byregulating PETN in B cells of pSS. MiRNA-7 has certain clinical value for disease activity evaluation.

Three osmotolerant yeasts were isolated from three batches of "swollen can" soy sauce produced by a Guangdong condiment plant. These strains grew faster in the media containing 50%～60% glucose or 15% NaCl than in common yeast media. The three yeasts were identified as Pichia etchellsii by using morphological characteristics, physiological and biochemical tests.

Objective To evaluate the therapeutic effects of taurine combined with silybin meglumine in patients with non-alcoholic steatohepatitis (NASH). Methods One hundred patients with NASH were divided into two groups with 50 for each. The patients in the control group received polyene phosphatidyl choline (456 mg) combined with silybin meglumine (100 mg) 3 times daily for 24 weeks. While those in the treatment group received taurine (2 g) combined with silybin meglumine (100 mg) 3 times daily for 24 weeks. All patients were asked to take up basic therapy including drinking without alcohol, restricting sugary and fatty intake, improving food structure, carrying moderate aerobics and lightening body weight. Results At the end of 24 weeks, the clinical symptoms and the liver function ameliorated in two groups. Ultrasonic or CT examination showed that the steatohepatitits was improved significantly in two groups. Additionally, the levels of blood glucose, serum triglyceride and cholesterol as well as BMI decreased simultaneously (all P value <0. 05). Whereas the treatment group was superior to control group in aspect of amelioration of inappetite, nausea and vomiting as well as lever of serum triglyceride (all P value <0. 05). There was no side effect in the treatment group. Conclusion Based on the basic therapy, taurine combined with silybin meglumine can mitigate the degree of NASH, improve the metabolism of blood glucose and lipid with few side-effects.
