Objective To investigate the diagnosis/misdiagnosis reason/treatment of residual gallbladder stone with choledocholithiasis.Methods The clinical data of 34 patients with residual gallbladder,16 cases of them suffered from choledocholithiasis additionally were retrospective analyzed.Results 14 cases were treated by residual cholecystectomy +choledochotomy +T -tube drainage,2 cases were were treated by choledochotomy + T -tube drainage.Preoperative misdiagnosis of residual gallstones rate was 56.3% (9 /16 ),7 cases were found residual gallstones during operation.The other 2 cases were misdiagnosed residual gallstones.The rate of intraoperative and postoperative misdiagnosis was 12.5% (2 /16 ).18 cases with residual gallstones,16 cases underwent residual cholecystectomy,2 cases who were suspected with choledocholithiasis underwent residual cholecystectomy +choledo-chotomy,T -tube drainage.18 cases had no preoperative and postoperative misdiagnosis.Conclusion The clinical symptom of residual gallbladder stone with choledocholithiasis was similar to residual gallstones,often characterized by upper abdominal pain,fever,chills,jaundice,abdominal distension and other symptoms.It is difficult for preoperative imageological diagnosis that less than 3 cm residual gallbladder and small stones.When choledocholithiasis at the same time,needing more intraoperative careful dissect cystic duct and common bile duct,completes the cystic duct and common bile duct exploration,reducing misdiagnose residual gallstones.

Objective:To investigate of AIDET communication model in caring for type 2 diabetes mellitus of hospitalized patients.Methods:A total of 113 patients with type 2 diabetes mellitus treated in our department from January 2018 to November 2019 were enrolled, and divided into the control group(receiving a conventional communication mode)and the observation group(receiving an AIDET communication mode)according to a time order in the selecting of the research patients.The changes of self-care behavior and glucose metabolism index were evaluated and analyzed between the two groups.Results:On admission, the fasting blood glucose, 2-h postprandial blood glucose and glycosylated hemoglobin were(9.1±1.7)mmol/L, (13.8±2.9)mmol/L and(8.4±3.5)% in the observation group, and(9.4±2.1)mmol/L, (14.1±3.2)mmol/L and(8.1±2.9)% in the control group, respectively, with no statistically significances( P>0.05). At discharge, the observation group versus the control group showed a statistically significantly improved levels in FPG of(5.9±1.5)mmol/L vs.(7.8±1.9)mmol/L, in 2h-PBG of(10.1±3.7)mmol/L vs.(12.8±3.9)mmol/L and in glycosylated hemoglobin of(6.3±1.2)% vs.(7.5±0.9)%, respectively( P<0.05). The scores of management of poor blood glucose, foot care, blood glucose monitoring, medication compliance, regular exercise and diet control were higher in the observation group than in the control group at discharge( P<0.05). Conclusions:The application of AIDET communication mode can effectively enhance the self-care behavior of patients and help improve the glucose metabolism in hospitalized patients with type 2 diabetes mellitus.It has very positive effects on controlling the development of type 2 diabetes mellitus and improving the quality of life.

OBJECTIVEThis work investigated mesenchymal stem cells (MSCs) modified with Runt-related transcription factor 2 (Runx2) therapy for bone regeneration in rabbit mandibular distraction osteogenesis.

METHODSForty-eight New Zealand mature white rabbits were randomly divided into three groups after the rabbit model of mandibular distraction osteogenesis was established: reconstruction plasmid modified with Runx2 (group A), plasmid without Runx2 (group B), and the same dose of saline as control (group C). At the fifth day of distraction phase, MSCs with reconstruction plasmid modified with adv-hRunx2-gfp were injected into the distraction gap of group A. MSCs with reconstruction plasmid modified with adv-gfp was injected into the distraction gap of group B, whereas group C was injected with the same dose of saline. At 8 weeks after injection, all animals were sacrificed, and the distracted mandibles were harvested. The general imaging histological observation and three-point bending test were used for evaluation.

RESULTSCT plain scan and histological analysis confirmed that the amount of new bone forming in the distraction gap of group A was significantly higher than those in groups B and C. Dual-energy X ray and three-point bending test results also showed that the bone mineral density, bone mineral content, and maximum load of the distraction gap of group A were significantly higher than those of groups B and C (P<0.01).

CONCLUSIONRunx2-ex vivo gene therapy based on MSCs can effectively promote the bone regeneration in rabbit mandibular distraction osteogenesis and shorten the stationary phase. Therefore, reconstruction of craniofacial fracture would be a valuable strategy

An ultra-high performance liquid chromatography-tandem mass spectrometry ( UHPLC-MS/MS ) method was developed and validated for the simultaneous determination of 9 kinds of trace endocrine disrupting chemicals in biological samples using ultrasonic-assisted extraction followed by purification with gel permeation chromatography ( GPC) and silica gel columns. The sample extracts were purified by Bio beads S-X3 GPC columns with cyclohexane/ethyl acetate (1:1, V/V) as mobile phase, and the target compounds were eluted in the fraction of 12-28 mL retention volume. Electrospray ionization source operated in positive mode and atmospheric pressure chemical ionization source operated in negative mode were used for mass spectrometric detection. Data acquisition was carried out in multiple reaction monitoring mode. Recoveries were predominately within 65 . 2%-118 . 0%. Method quantification limits were 0 . 1-9 . 7 ng/g dw ( dry weight ) . This method was successfully applied to the analysis of the target endocrine disrupting chemicals in carps collected from the Pearl River. with the exception of carbanilide and triclocarban, the rest analytes were detected in fish tissue samples, with the concentrations varied within the range of 0. 1-22. 6 ng/g dw.

BACKGROUND:During the healing of fractures, removal of sciatic nerve can result in insufficient mechanical rigidity of newborn woven bone. However, there are less reports concerning the denervation effects during distraction osteogenesis. OBJECTIVE:To observe the effect of removal of the sciatic nerve on bone regeneration and the expression of Runt-related transcription factor 2 (Runx2) protein during distraction osteogenesis in a rabbit model. METHODS:Twenty-four adult male New Zealand rabbits were selected and underwent left tibial osteodistraction to construct animal models of distraction osteogenesis. Before distraction, the animals were randomly divided into group R (resecting the left sciatic nerve) and group I (intact left sciatic nerve). Six weeks after completion of distraction, the animals were kil ed and the lengthened tibias were harvested for radiography, three-dimensional CT reconstruction, histological evaluation, connectivity density (Conn.D) evaluation. RESULTS AND CONCLUSION:New regenerated bone was present and Runx2 protein was expressed in the distraction gaps of al animals at the end of the study, as revealed by radiography, three-dimensional CT reconstruction, and histological observation. However, less new bone formation and a lower degree of mineralization and expression of Runx2 protein were observed in group R compared with group I. The results suggest that the denervation appears to have an inhibitory effect on bone formation and the expression of Runx2 protein during distraction osteogenesis.

Objective:To investigate the immune response characteristics of helper T cells Th1, Th2, Th17 and their related cytokines in acute, chronic and recovery phases after Brucella infection. Methods:Using prospective study, a total of 130 patients with brucellosis in the First Affiliated Hospital of Medical College of Shihezi University from January 2017 to December 2018 were selected as the research subjects, including acute phase group (49 cases), chronic phase group (44 cases), recovery phase group (37 cases), and 30 cases of healthy physical examination during the same period were included in the control group. The peripheral blood samples of all subjects were collected, and flow cytometry was used to detect Th1, Th2 and Th17 cells in the peripheral blood; the cytometry bead array (CBA) was used to detect the serum cytokines interferon-γ (IFN-γ), interleukin (IL)-4 and IL-17A expression levels.Results:In the control, acute phase, chronic phase and recovery phase groups, the differences of the expression ratios of Th1 [(1.03 ± 0.85)%, (5.46 ± 3.54)%, (4.48 ± 2.26)%, (2.29 ± 2.25)%], Th2 [(4.72 ± 2.36)%, (7.00 ± 3.14)%, (13.99 ± 9.14)%, (5.89 ± 4.69)%], and Th17 cells [(2.09 ± 0.48)%, (3.04 ± 2.17)%, (3.61 ± 2.67)%, (2.74 ± 2.58)%] were statistically significant ( F = 20.95, 21.15, 2.90, P < 0.05). Compared with the control group, the expressions ratio of Th1, Th2, Th17 cells in acute and chronic phase groups and Th1 cells in recovery phase group were significantly higher ( P < 0.05); compared with the recovery phase group, the expressions ratio of Th1, Th2 and Th17 cells in acute and chronic phase groups were significantly higher, but the expression ratio of Th2 cells in acute phase group was lower than that in chronic phase group ( P < 0.05). The expression levels of IFN-γ, IL-4, and IL-17A in serum of control group, acute phase, chronic phase and recovery phase groups were significantly different ( F = 7.79, 15.85, 7.55, P < 0.05); compared with the control group, the expression levels of IFN-γ, IL-4, IL-17A in acute and chronic phase groups and IFN-γ, IL-4 in recovery phase group were significantly higher ( P < 0.05); compared with the recovery phase group, the expression levels of IFN-γ, IL-4, IL-17A in acute phase group and IFN-γ, IL-17A in chronic phase group were significantly higher ( P < 0.05). The expression ratio of Th1 cells in recovery phase patients who finished treatment for less than 12 months was significantly higher than that of recovery phase patients who finished treatment for ≥12 months ( t = 2.26, P < 0.05). Conclusions:After patients are infected with Brucella, Th1 cell immunity is dominant in acute phase, Th2 cell immunity is dominant in chronic phase, and there is no significant difference in the response of Th17 cell immunity between acute and chronic phases. The immune function of patients in the recovery phase may still be abnormal when the treatment time is less than 12 months. Some clinically cured patients in the recovery phase still have a relatively high proportion of Th1 cells, suggesting that the patient's immune function has not fully recovered.

Objective To assess the effectiveness of traditional Chinese Medicine (TCM ) syndrome differentiation treatment for diabetic nephropathy in elderly patients. Methods A total of 96 elderly patients with diabetic nephropathy admitted to our hospital from January 2015 to December 2017 were recruited and divided into a regular care group (n= 48)and a TCM group(n= 48).Both groups received conventional treatment ,with TCM syndrome differentiation treatment added to the TCM group. The effectiveness of the treatment modalities was compared. Results In the regular care group ,significant effectiveness was observed in 12 patients ,effectiveness in 24 patients ,and ineffectiveness in 12 patients ,with a total effectiveness rate of 75％ .In the TCM group ,significant effectiveness was seen in 18 patients ,effectiveness in 27 ,and ineffectiveness 3 ,with a total effectiveness rate of 93％. The total effectiveness rate of the TCM group was higher than that of the regular care group(χ2 =6.400 ,P=0.011).After treatment ,fasting blood glucose ,2 h postprandial blood glucose , urea nitrogen ,creatinine ,and 24 h urine protein in the TCM group were significantly lower than in the regular care group and than pre-treatment levels(P<0.05). Conclusions TCM differentiation can not only significantly improve the treatment effectiveness in elderly patients with diabetic nephropathy ,but also relieve the clinical symptoms.

OBJECTIVETo study the clinicopathological features and prognosis of multifocal gastric cancer.

METHODSClinicopathological data of 30 cases with multifocal gastric cancer from January 2003 to March 2014 in our department were retrospectively analyzed. Random selection of 100 cases of single focal gastric cancer patients admitted in the same period was used as control group. Clinicopathological features and prognosis were compared between two groups.

RESULTSSix(20.0%) multifocal gastric cancer patients had 3 or more focuses with different differentiation degrees at the same time. The age of multifocal gastric cancer patients was younger than that of single focal gastric cancer [(56.8±16.4) year vs. (63.3±10.8) year, P<0.05]. The TNM stage of multifocal gastric cancer was mainly stage I((73.3%, 22/30), and the TNM stage of single focal gastric cancer was mainly stage III((64.0%, 64/100). As compared to single focal gastric cancer group, multifocal gastric cancer group had smaller tumors, lower ratio of nerve invasion and lymphatic vascular invasion(all P<0.01). Five-year survival rate was higher in multifocal gastric cancer group as compared to single focal gastric cancer group(76.0% vs. 48.8%, P<0.05). The prognosis of multifocal gastric cancer patients was associated with tumor size, nerve invasion, vascular invasion, depth of tumor invasion, lymphatic metastasis and TNM staging(all P<0.05), which was similar to single focal gastric cancer patients. Differences of 5-year survival rate under various clinicopathological conditions were not significant between two groups(all P>0.05).

CONCLUSIONMultifocal gastric cancer patients have earlier staging tumor and overall advantage as compared to those with single focal gastric cancer.
