Objective To discuss the methods of treating diabetes merged oral and maxillofacial space infec-tion and their effects.Methods Clinical data of 20 patients with diabetes merged oral and maxillofacial space infec-tion were retrosepectively analyzed.Results All 20 cases of patients with diabetes merged oral and maxillofacial space infection were cured.The mean length of treatment was (18.4 ±2.8)days.There were 20 cases of positive results of bacterial culture,the positive rate was 100%,and there were 15 cases of streptococcal infection,4 cases of klebsiella pneumoniae infection,1 case of candida albicans infection.20 cases of patients was given incision and drainage,4 cases given incision of trachea.Conclusion It was easier for patients with diabetes having maxillofacial space infection,and more serious illness,more difficult for treating.Local infection should be treated,and systemic conditions should be improved as well.The risks of occurrence of serious complications should be reduced.

Objective To explore the effects of carbon monoxide(CO) on hydrogen sulfide(H_(2)S) / cystathionine-?-lyase(CSE) system in thoracic aorta of rats.Methods Twenty-seven thoracic aortae of 9 Wistar rats were divided into control group,hemin group(the final concentration of hemin was(10~(-4)mol/L)) and zinc protoporphyrin group(the final concentration of zinc protoporphyrin was(10~(-5)mol/L)).Sulfide electrode method was used to measure the content of hydrogen sulfide in supernatant and the production rate of hydrogen sulfide in homogenate.Results Compared with the control group,hydrogen sulfide in supernatant was significantly increased(P

The high-intensity interval training often consisted of groups of interval high-intensity exercise of exhaustion or above 90%maximal oxygen consumption, which can be applied to improve aerobic capacity. Adaption of skeletal muscles might be resulted from high-intensity interval training, including recruitment, glucose metabolism and activity of mitochondrial oxidase, etc., and improve maxi-mum oxygen uptake. It has been used for physical fitness, such as weight reduction, rehabilitation of heart diseases and diabetes mellitus, etc.

Neuroblastoma is the most common extra-cranial solid tumor in infants and children,which is very easy to metastasis and its malignant degree is very high.Because of its clinical differences,so far treatment of neuroblastoma is still difficult.Currently comprehensive therapies,including surgery,chemotherapy,radiation,stem cell transplantation,131 I-meta-iodobenzylguanidine therapy,biological therapy and immune therapy as well as target therapy dominant the treatment of this disease,and introduce the some of the treatment protocols for this disease.

ObjectiveTo evaluate the efficacy and safety of tolterodine tartrate in treating patients with early overactive bladder(OAB) symptoms after transurethral resection prostate (TURP).Methods Thirty-one patients who received TURP and were found OAB at recent follow-up were enrolled and divided by random digits table method into study group ( 16 cases) and control group ( 15 cases).The patients in study group were treated with 2 mg tolterodine tartrate twice a day for four weeks,while the changes of OAB in control group were observed.The OAB symptoms score (OABSS),maximum flow rate(Qmax),24 h urination and adverse reactions during the period of medication of two groups before and after treatment were recorded and observed.Results The second evaluation,all the indexes except Qmax in study group improved significantly compared with those of the first evaluation in study group and control group the second evaluation.The indexes included urination times[(6.8 ± 1.0) times vs.( 12.5 ± 1.5) times,(11.8 ± 1.2)times],urgency times[(1.4 ± 1.1) times vs.(4.1 ±2.2) times,(4.1 ±2.3) times],urine volume [(214 ±36) ml vs.( 177 ± 46) ml,( 178 ± 44) ml ],nocturia times [ ( 1.9 ± 0.7) times vs.(2.9 ± 1.3 ) times,(2.8 ±1.4) times ],urge incontinence times [ (0.6 ± 0.5 ) times vs.( 1.6 ± 1.0) times,( 1.5 ± 1.0) times ].OABSS in study group the second evaluation was significantly lower than that in the first evaluation in study group and the second evaluation in control group [ (3.6 ± 1.8 ) scores vs.( 7.6 ± 3.3 ) scores,(7.4 ± 3.2) scores,P ＜ 0.01 or ＜ 0.05 ].There was no statistical significance in all the indexes in control group between the first evaluation and the second evaluation (P ＞ 0.05).There were 2 cases with adverse reactions which performed as dry mouth which could be tolerant.ConclusionTolterodine tartrate is efficient and safe in treating patients with early OAB symptoms after TURP.

Objective To analyze the clinical value of sTNFR-1,sIL-2Ra and IGF-1 on depression in patients with esophageal cancer by comprehensive nursing intervention and explore the possibility of serum indicators to replace DSI and HAMD. Methods 120 patients with pathologically confirmed esophageal cancer were included in the study.Zung depression status inventory (DSI)and hamilton depression rating scale (HAMD)were used to assess depression.Serum sTNFR-1,sIL-2Ra and IGF-1were detected by enzyme-linked immunosorbent assay (ELISA).Results 69 patients were classified as anxiety and depression group,51 patients were as normal control group.There were 32 patients with depression.Serum sTNFR-1, sIL-2Ra and IGF-1 levels in study group was higher than that in the control group (P<0.05)and these serological indexs increased from the minimal depression,mild-to-moderate depression group to severe depression group (P<0.05).Conclusion Serum sTNFR-1,sIL-2Ra and IGF-1 levels may be used as evaluation index of nursing intervention,but need further clini-cal validation.

Objective: To explore the effects of ligustrazine on the secretion of hydrogen sulfide in the ventricular tissues of rats under physiological condition.Methods:32 rats were divided into control group,high dose group of ligustrazine(150?g/ml),medium dose group of ligustrazine(15?g/ml) and low dose group of ligustrazine(1.5?g/ ml) at random.The left and right ventricular tissues were incubated in 37℃ thermostatic water bath for 4 hours with Krebs solution as supernatant.After incubation of the ventricular tissues,the sensitive electrode-based method was used to detect the content of H2S in the supernatant.Results: In the left ventricular tissues,there were on dif-ference of the H2S level betweenthe 1.5?g/ml ligustrazine group(0.17?0.03),15?g/ml ligustrazine group(0.17?0.03)and control group.However,compared with control group, the H2S level in hige dose group of ligustrazine decreased obviously(P0.05),but the H2S level in the 150?g/ml ligustrazine group(0.46?0.09)was significantly lower than that in the control group(0.64?0.13)(P

Objective To explore the effect of hydrogen sulfide(H2S) on intercellular adhesion molecule-1(ICAM-1) in the pathogenesis of atherosclerosis in apoE knockout(apoE-/-) mice.Methods Six week-old C57BL/6J and apoE-/-mice were divided into control C57BL/6J group,apoE-/-group,apoE-/-+ sodium hydrosulfide(NaHS,a donor of H2S) group and apoE-/-+ DL-propargylglycine(PPG,an inhibitor of H2S synthase).There were 8 mice in each group.They were fed chow diet for 10 weeks.Serum H2S was measured by sulfide electrode-based method,serum ICAM-1 was determined by ELISA.Aortic ICAM-1 mRNA was detected by RT-PCR.The changes of atherosclerosis plaque size were observed by oil red O staining.Results Serum H2Slevel significantly decreased in apoE-/-mice(P

NG-nitro-D-arginine (D-NNA) produced pressor responses in rats by acting via chiral inversion intoNG-nitro-L-arginine (L-NNA), an inhibitor of nitro oxide synthase. The present investigation aimed to study the roleof the D-amino acid oxidase (DAAO) in chiral inversion of D-NNA and the relationship between DAAO activitieson various D-amino acids and their inversion rate. Benzoate (400 mg/kg) or creatinine (400 mg/kg), two inhibitorsof DAAO, blocked D-NNA-induced pressor responses in rats. Furthermore, the addition of the pure DAAOsignificantly potentiates L-NNA production rate in kidney homogenates by approximately 2-folds. The in vivo andin vitro results suggested that DAAO plays an essential role in the pressor responses elicited by D-NNA.Moreover, crude DAAO solution from the kidney showed marked selection (the maximal ratio of Kcat/Km wasnearly 15 times) on different D-amino acids that exhibited similar chiral inversion rate in vivo, suggesting that otherenzymes, such as transaminase, are also required for the entire process of D-NNA chiral inversion.
