ABSTRACT
Objective:To compare serum procalcitonin and fibrinogen degradation product levels between type 2 diabetes mellitus patients with Escherichia coli bloodstream and urinary tract infections. Methods:The clinical data of 82 type 2 diabetes mellitus patients with Escherichia coli infections who received treatment between December 2014 and December 2019 in the First Affiliated Hospital of Datong University (The Fifth People's Hospital of Datong) were retrospectively analyzed. These patients were assigned to bloodstream infection ( n = 40) and urinary tract infection ( n = 42) according to the way of Escherichia coli infection. Serum procalcitonin and fibrinogen degradation product levels, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, C-reactive protein, white blood cell count, D-Dimer level, antithrombin III activity, and electrolytes were determined and compared between the two groups. Correlation between procalcitonin and other variables was analyzed. Multiple linear regression analysis was performed with procalcitonin level as a dependent variable and other relevant indexes as independent variables. Results:Body temperature, white blood cell count, neutrophil count, monocyte count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, procalcitonin level, C-reactive protein level, fibrinogen degradation product level, and D-Dimer level in the bloodstream injection group were (39.49 ± 0.64) ℃, (14.92 ± 11.78) × 10 9/L, (13.39 ± 11.60) × 10 9/L, (0.72 ± 0.36) ×10 9/L, (14.86 ± 10.52), (199.15 ± 160.69), (22.81 ± 17.86) μg/L, (133.44 ± 63.63) mg/L, (49.71 ± 41.44) mg/L, (16.56 ± 12.20) mg/L, respectively, which were significantly higher than those in the urinary tract infection group [(37.12 ± 1.20) ℃, (9.04 ± 3.95) × 10 9/L, (6.25 ± 4.02) × 10 9/L, (0.42 ± 0.29) × 10 9/L, (3.67 ± 3.34), (120.01 ± 44.08), (4.46 ± 8.69) μg/L, (39.22 ± 22.16) mg/L, (3.81 ± 3.41) mg/L, (0.84 ± 0.75) mg/L), t = 7.356, 2.578, 3.162, 2.958, 5.538, 2.591, 2.810, 4.825, 2.902, 2.375, all P < 0.05]. Platelet count, lymphocyte count, blood sodium level and antithrombin Ⅲ activity in the bloodstream infection group were (167.50 ± 104.93) × 10 9/L, (1.06 ± 0.58) × 10 9/L, (130.89 ± 6.50) mmol/L, (57.88 ± 16.28)% , which were significantly lower than those in the urinary tract infection group [(239.40 ± 82.52)× 10 9/L, (2.14 ± 0.71) × 10 9/L, (138.46 ± 5.96) mmol/L, (90.11 ± 8.90)%, t = -2.853, -6.313, -4.046, -7.350, all P < 0.05]. Correlation analysis revealed that serum procalcitonin level was positively correlated with body temperature ( r = 0.387), white blood cell count ( r = 0.355), neutrophil count ( r = 0.368), C-reactive protein ( r = 0.605), fibrinogen degradation product level ( r = 0.616), D-Dimer level ( r = 0.486) (all P < 0.05), and it was negatively correlated with sodium level ( r = -0.319) and antithrombin Ⅲ activity ( r = -0.465) (both P < 0.05). Multiple linear regression analysis results revealed that fibrinogen degradation product level and body temperature were greatly correlated with procalcitonin level. Conclusion:Inflammatory indicators procalcitonin level, body temperature, white blood cell count, neutrophil count, C-reactive protein, fibrinogen degradation product level and D-Dimer level were remarkably higher in type 2 diabetes mellitus patients with Escherichia coli bloodstream infection than those in type 2 diabetes mellitus patients with Escherichia coli urinary tract infection. Procalcitonin level was greatly correlated with body temperature and fibrinogen degradation product level.

Objective:To investigate the clinical characteristics of different stages of type 2 diabetic nephropathy(DN), and to explore the possible factors affecting visceral fat area (VFA).Methods:From September 2018 to March 2019, 464 patients with type 2 diabetes who were hospitalized in the First Affiliated Hospital of Datong University were selected.Among them, 315 patients with urinary albumin/creatinine ratio(UACR)<30 mg/g were selected as normal proteinuria group, 72 patients with UACR 30-299 mg/g were selected as microalbuminuria group, 45 patients with UACR>300 mg/g were selected as massive proteinuria group, and 32 patients with serum creatinine higher than the reference value were selected as renal failure group.The serum creatinine of the first three groups was in the normal range.The clinical data of these patients such as blood pressure, body mass index(BMI), VFA, subcutaneous fat area(SFA), brachial-ankle pulse wave velocity(BAPWV), blood lipid, renal function and blood sugar were collected and compared among the four groups.Using VFA as strain and other indicators as independent variables, multivariate linear regression analysis was carried out.Results:There were statistically significant differences among the four groups in age, height, weight, BMI, head circumference, neck circumference, waist circumference, hip circumference and waist-hip ratio ( F=15.580, 4.679, 6.186, 3.553, 3.153, 2.689, 5.170, 3.114, 3.535, all P<0.05). The VFA of the normal proteinuria group, microalbuminuria group, massive proteinuria group and renal failure group were (102.25±37.09)cm 2, (104.12±40.93)cm 2, (119.63±48.82)cm 2, (110.54±41.58)cm 2, respectively, and the BAPWV were (1 546.97±330.18)cm/s, (1 595.52 ±381.27)cm/s, (1 459.63±285.61)cm/s, (1 703.89±318.64)cm/s, the differences were statistically significant among the four groups( F=3.344, 4.020, all P<0.05). There were statistically significant differences in alanine aminotransferase, creatinine, uric acid, total cholesterol, red blood cell, hemoglobin, ratio of neutrophils to lymphocytes (NLR) and ratio of platelets to lymphocytes (PLR) among the four groups ( F=3.405, 15.535, 6.552, 2.803, 6.158, 15.580, 3.764, 3.262, all P<0.05). With VFA as strain, multivariate linear regression analysis showed that waist circumference, BMI, TG and BAPWV were risk factors for VFA. Conclusion:DN is associated with multiple obesity-related indicators and inflammatory indicators such as NLR, PLR; VFA is associated with BAPWV.
ABSTRACT
Objective:To investigate the relationship between procalcitonin(PCT) and insulin resistance in diabetic foot infection.Methods:Sixty patients with diabetic foot infection hospitalized in the Fifth People's Hospital of Datong from March 2015 to March 2017 were selected and divided into three groups according to the value of PCT: slightly elevated group(L group, n=18), moderately elevated group(M group, n=21), highly elevated group(H group, n=21). Another 20 patients with type 2 diabetes mellitus were collected as control group.The PCT, C-reactive protein(CRP), white blood cell count(WBC), fasting and postprandial blood glucose, fasting insulin and insulin resistance index(HOMA-IR) were calculated and compared. Results:In the control group, the levels of PCT, HOMA-IR, CRP and WBC were (0.14±0.12)μg/L, (17.70±8.86), (32.90±24.19)mg/L, (8.01±2.21)×10 9/L, respectively, which in the L group were (0.31±0.14)μg/L, (20.42±9.71), (50.85±27.81)mg/L, (9.95±3.35)×10 9/L, respectively, which in the M group were (1.11±0.52)μg/L, (24.08±14.09), (64.31±40.21)mg/L, (10.86±2.25)×10 9/L, respectively, which in the H group were (5.31±3.04)μg/L, (31.73±14.13), (72.29±50.26)mg/L, (12.51±5.51)×10 9/L, respectively, and there were statistically significant differences among the four groups( F=50.744, 5.195, 4.303, 5.252, all P<0.01). With the increase of PCT, the levels of WBC, CRP and HOMA-IR were increased, and HOMA-IR was positively correlated with PCT( r=0.265, P=0.017). Conclusion:Serum level of PCT has correlation with infection degree of diabetic foot and is positively correlated with insulin resistance.

ABSTRACT
Objective To observe the local field potential activity of dorsomedial and dorsolater striatal (STR) neurons in rats with exercise-induced fatigue,so as to explore the regional characteristics of those neurons.Methods Thirty-six male Wistar rats were randomly divided into a control group(CG),a single fatigue group(SFG)and a repeated fatigue group(RFG),each of 12.The exercise-induced fatigue model was established according to a load-increasing treadmill running protocol.The CG did not do any treadmill running,SFG finished one-time exhaustive exercise while the RFG repeated exhaustive exercise 6 times.The extracellular glass microelectrode technique was used to record the spontaneous firing of dorsomedial(n=6)and dorsolateral(n=6)STR neurons in vivo to observe the discharging frequency,characteristics and types.Results (1)Spontaneous firing frequencies of striatal neurons in SFG were significantly higher than those of CG(P＜0.01),while those of RFG were significantly lower than SFG.(2) After repeated fatigues,there were significant decreases in the irregular firing pattern and significant increase in the explosive firing of striatal neurons compared with CG(P＜0.05).(3)After the single fatigue and repeated fatigue,the discharging frequency of dorsomedial medium spiny-like neurons increased significantly(P＜0.05),and that after repeated fatigue significantly higher than that of the dorsolateral(P＜0.01).The discharge frequency of the dorsomedial and dorsolateral fast-spiking neurons decreased significantly after repeated fatigues.The discharge frequency of dorsolateral large aspiny-like neurons of RFG was significantly higher than SFG,while that of the latter was significantly lower than CG(P＜0.05).Conclusions (1)Striatal neurons mediate exercise-induced fatigue and present regional characteristics,which might be due to dorsomedial and dorsolateral striatal neurons receiving different types of projection neurons.(2) Striatal fast-spiking neurons may play an important role in mediating the exercise-induced fatigue.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the changes of anticancer efficiency of 5'-deoxy-5-fluorouridine (5'-DFUR) and 5-fluorouracil (5-Fu) in colorectal cancer cell line HT29 and LS174T cells after transfection of thymidine phosphorylase (TP) cDNA with a lentiviral vector.</p><p><b>METHODS</b>TP cDNA was transfected into human colorectal cancer cell lines HT29 and LS174T with the lentiviral vector pLenti6.3-MCS-IRES2-EGFP, and the transfection efficiency of the two cell lines passed 5 generations was analyzed by flow cytometry. The expression of TP protein and the relative quantitative expression of TP mRNA in these 2 cell lines were detected by Western blot and RT-PCR, respectively. The 50% inhibitory concentration (IC50) of 5'-DFUR and 5-Fu in both HT29 and LS174T parent cells and TP-transfected cells were assessed by MTS assay. Finally, the concentration of converted 5-Fu was detected by high performance liquid chromatography (HPLC) either in the medium containing a series of concentrations of 5'-DFUR, in which HT29/HT29-TP or LS174T/LS174T-TP cells were cultured, or in the cell culture lysates.</p><p><b>RESULTS</b>The HT29 and LS174T cells transfected with human TP cDNA were monitored for 5 generations, and their transfection efficiency was about 95.0%. Immunohistochemical staining showed that both the parent cells and TP-transfected HT29 and LS174T cells were TP-positive, while vector-transfected cells were TP-negative. Western blotting showed that the TP protein expression in HT29-TP and LS174T-TP cells were significantly increased compared with that in their parents cells. The relative quantity (RQ) values of TP mRNA in HT29-TP and LS174T-TP cells were 8.45 ± 0.15 and 2 615.02 ± 253.97, respectively, which were significantly higher than that in their parents cells (P < 0.01). The IC50 values of 5'-DFUR on HT29-TP cells and its parents cell were (14.33 ± 0.74) µmol/L and (707.66 ± 5.66) µmol/L, respectively (P < 0.05), while (0.59 ± 0.11) µmol/L in LS174T-TP cells and (239.20 ± 21.83) µmol/L in its parent cells, respectively (P < 0.05). The IC50 values of 5-Fu of HT29-TP cells and its parents cells were (5.42 ± 0.75) µmol/L and (14.19 ± 0.97) µmol/L, respectively (P < 0.05), while (4.41 ± 0.96)µmol/L in LS174T-TP cells and (16.42 ± 2.12)µmol/L in its parents cells, respectively (P < 0.05). The HPLC results showed that the 5-Fu concentration detected from media contained a series of concentrations of 5'-DFUR for culturing HT29-TP and LS174T-TP cells were 12.2 to 28.7-folds and 13.1 to 23.6-folds, respectively, higher than that in their parents cells, (P < 0.01 for all). Otherwise, just a little of 5-Fu was detected in the two TP-transfected cells lysate, about 0.9% to 4.2% of 5-Fu detected in the media of the same cultured cells, whereas no 5-Fu was detected in the two parent cell lysates.</p><p><b>CONCLUSIONS</b>Transfection of TP cDNA into colorectal cancer cell lines HT29 and LS174T with lentiviral vector can improve the expression of both TP mRNA and TP protein levels in passaged cells, enhance the conversion of 5-Fu from 5'-DFUR in the medium, and result in an enhanced anticancer effect on these two cell lines.</p>

ABSTRACT
This study is to screen the Chinese herbal compounds which could inhibit the production of Abeta and investigate the underlying mechanism. Ten types of compounds which have potential value in the treatment of AD were selected as initial screening trial. The cell models which used could overexpress Abeta and beta-secretases or Abeta and gamma-secretases. Extracellular Abeta was determined by ELISA after the cell models treated with different concentrations of compounds (0.5-100 micromol x L(-1)), separately. Then the compounds were selected which could inhibit extracellular Abeta and their best concentration ranges were decided, too. Furthermore, the cell viability and apoptosis rate, the level of intracellular Abeta, beta and gamma-secretases were determined after the cell models treated with different concentrations of selected compounds. The results showed that 4 of the 10 compounds could reduce the level of extracellular Abeta; they were cryptotanshinone, astragalosides, gastrodin and paeoniflorin, and their best concentration ranges were 0.5-5.0, 0.5-5.0, 5.0-50, 1.0-25 micromol x L(-1), respectively. Further study indicated that the 4 selected compounds were nontoxic to the cellular models and lowering intracellular Abeta were more effective compared with extracellular; of which astragalosides and gastrodin showed dose-dependent inhibition to the activities of beta and gamma-secretases, with the maximum inhibiting rates of 78.2% and 80.3%, respectively. In conclusion, cryptotanshinone, astragalosides, gastrodin and paeoniflorin could inhibit the expression and secretion of Abeta, and the underlying inhibiting mechanism of astragalosides and gastrodin were related with the reduction of the beta and gamma-secretase activities, respectively.

ABSTRACT
ObjectiveTo evaluate the anticancer activity of 5'-dexoxy-fluorouridine on colon cancer experimental models in BALB/C mice,compared with 5'-fluorouracil,an anticancer agent widely used in clinic,meanwhile,examined the conversion of 5'-Dexoxy-fluorouridine to 5' -fluorouracil in cancer tissues and serum of mouse models.MethodsThe xenografts of mouse colon cancer cell line CT 26 were transplantated to cecum in 60 male BALB/C mice.Three days lated,these mice were divided into 3 groups and intro- peritoneally injected:( 1 ) 5' - dexoxy- fluorouridine 0.1 mg/g,(2) 5' - Fluorouracil 0.02 mg/g,(3)0.9％ sodium chloride 0.4 mL (as a control),respectively.Two and three weeks later,6 mice were sacririced in every group respectively to measure the weight of tumors and bodies,to examine the Hb,RBC,WBC,PLT,AST,ALT,UREA,and CREA in blood.The rest 8 mice in each group were fed generally,and the survival time from operation to natural death was recorded.In addition,14 mice with xenografts of CT 26 about 2 weeks,were divided into 2 groups averagely,5' -dexoxy-fluorouridine 0.1 mg/g and 5' -fluorouracil 0.02 mg/g were intro-peritoneally injected respectively.Fifteen min later,the converted 5' -fluorouracil was detected from the blood and tumor tissues in sacrificed mice.ResultsThe lest tumor average weight was found in the mice injected 5 '-dexoxy-fluorouridine,being (0.07 ± 0.12) g and (0.24g ±0.29) g for the mice sacrificed at 2 and 3 weeks later,respectively.The average survival time for rest mice was ( 32.6 ± 8.9) d.The average tumor weight in 5' - fluorouracil group was (0.74 ± 0.43 ) g and ( 1.13 ±0.75) g at 2 and 3 weeks later,and the average survival time for the rest was (22.8 ±5.9)d,respectively.The average tumor weight in the control group was (0.70 ±0.47) g and ( 1.93 ±0.83) g at 2 and 3 weeks,and the average survival time for the rest was ( 17.5 ± 2.8 ) d.Either the average tumor weight or average survival time in the mice of 5 ' -dexoxy-fluorouridine group was significantly differen from either 5' -fluorouracil group or control (P ＜ 0.05 ).However,there was no significant difference for the numbers of WBC,PLC,Hb,and some function examination of liver and kidney among 3 group mice,besides the loss of weights in 5'-fluorouracil group mice after operation and medicine therapy which was significantly obvious than that in 5' -deoxy-fluorouridine and control groups ( P ＜ 0.05 ).In addition,( 54.71 ± 12.82) μg/g 5' -fluorouracil was detected in xenografts of mice injected 5' -dexoxy-fluorouridine 15 min later,which was the 6.20 folds of 5' -fluorouracil detected in serum from sthe ame group,P ＜0.05.However,( 133.35 ±20.69) μg/m 5'-fluorouracil were detected in serum of mice after 5' -fluorouracil were injected 15 min later,which was the 1.55 folds of 5' -fluorouracil detected in the xenografts from same group ( P ＜ 0.05 ).ConclusionsIn colon cancer tissues of mouse experimental models,5' - dexoxy- fluorouridine could be converted effectively to 5'-fluorouracil,an obvious high concentration being detected in serum of mice than in cancer tissues.The anticancer effect of 5'-dexoxy-fluorouridine on mouse colon cancer models was more effective than 5'-fluorouracil,resulting in a longer survival duration,less side effect and no significant injury on liver and kidney functions.However,the mechanism of 5' -dexoxy-fluorouridine converted to 5' -fluorouracil in cancer tissue is needed further investigation.
ABSTRACT
Objective To compare the efficacy of the radical resection by laparoscopy versus open approach in perioperative period on the patients with rectal carcinoma,and investigate the feasibility,safety and oncological clearance of the laparoscopy.Methods The clinical data of 44 patients who underwent radical resection of rectal carcinoma by laparoscopy in our hospital were reviewed and compared with another 53patients who underwent an open approach in the same period.The surgery-related data,postoperative recovery status,tumor radical resection index,and postoperative complications by laparoscopy were analyzed by statistics,and compared with those by open approach,and evaluated the deference of too kinds of operation.Results This study showed a longer surgical time (260.45 ± 67.46) min vs ( 179.25 ± 40.92) min,P ＜0.05,a less intra-operative blood loss( 125.20 ±61.80) mL vs ( 198.02 ± 131.24) mL,P ＜0.05,in laparoscopic group compared with open approach.Meanwhile,it also showed an earlier recovery of bowel functions for discharge gas from anus,taking in food,and out-of-bed activity (4.34 ± 1.55) d vs(5.45 ± 1.55) d,P ＜0.05,in the laparoscopic group compared with open approach.There was no statistical difference of incidence of post-operative complications (5 cases vs 11 cases,P ＞0.05) between the two groups and the laparoscopic approach was also equal to the open approach as regard to post-operative stay (15.34 ±6.62) d vs (16.82±5.73) d,P ＞0.05,and demand of intra-operative blood transfusion (4 case vs 8 cases,P＞0.05 ).Conclusions Compared with open surgery,the radical resection of rectal carcinoma by laparoscopy has shown obvious advantages in smaller incision,less blood loss,less pain,earlier recovery of bowel and bladder functions,and earlier out-of-bed activity.And it is also possible by laparoscopy approach to decrease the post-operative complications and post-operative stay.Meanwhile,there is no significant deference on oncological clearance for laparoscopy compared with open approach during perioperative period,while the long term follow-up data is still needed to support the results.
ABSTRACT
Objective To detect the tbymidine pbospborylnse (TP) expression in metastatic liver cancer tissues from human colorectal cancer by immunohistochemistry, and analyze the correlation between TP ex-pression and the tumor-associated macrophages (TAM), and the prognosis of patients. Methods Twenty-eight metastatic liver cancer specimens resected from patients with colorectsl cancer, were immunohistochem-ically stained by 654-1, an anti-TP monoclonal antibody, IC6-203, another anti-TP monoclonal antibody, PG-M1, anti-macrophage marker CD68 monoclonal antibody. Morphometrical analysis and positive cell counting were performed, and the correlation of TP expression with the patient's prognosis was evaluated. Results In normal liver tissues, the hepatic cells apart from cancer nests were weakly positive for 654-1 as well as for 1C6-203. The most TP-positive cells were distributed mainly along the invasive margin of cancer or around the cancer nests. In the corresponding areas, CD68-positive macrophages were also increased. The distribution patterns of CD68-positive cells were similar to those of TP-pesitive cells. The numbers of the TP-positive cells stained by 654-1 were significantly correlated with numbers of 1C6-203 positive cells (r=0.697, P<0.01), also correlated with the numbors of CD68-positive cells (r=0.703, P<0.01). While the numbers of 1C6-203 positive cells had no significant differences with the numbers of CD68-positive cells (r=0.359, P>0.05). The TP-pesitive cancer cells both for 654-1 and for 1C6-203 were detected only in 2 of 28 specimens. Both the number of TP-pesitive cells for 654-1 and 1C6-203, and the number of CD68-positive cells had no correlation with the survival period of patients. Conclusions In the metastatic liver cancer tissues of human colorectsl cancer, the TP-expreasinn stained by 654-1 was coincidence with 1C6-203, and the most important source of TP-expreasion is the TAM in stromal tissues around cancer nests, while the cancer cells are little expressed. The numbers of TP-positive cells stained by 654-1 are significantly related with CD68-pesitive macrophages, but not with the post-operation survival period of patients.
ABSTRACT
OBJECTIVE@#To study the changes of vestibular function in patients with diabetes mellitus and its clinical significance.@*METHOD@#Electronystagmography (ENG) was used to examine 76 patients with diabetes mellitus and 60 healthy adults subjects. After clinical detection of vestibular function including spontaneous nystagmus, positional test, head shaking nystagmus, neck torsion test, caloric test, and sensory organization tests which consist of gaze, saccade and smooth pursuit test, the results of these two groups were recorded for qualitative and quantitative statistical analysis.@*RESULT@#The rate of vestibular dysfunction in patients with diabetes mellitus were 68.4%. and that of the controls were 8.3%. There was significant difference between these two groups (chi2 = 15.472, P < 0.01).@*CONCLUSION@#Vertigo or dizziness occurred in patients with diabetes mellitus might be related to vestibular dysfunction. ENG test could be used as one of the objective clinical examinations in patients with diabetes mellitus.
