Objective To investigate the effect of one-lung ventilation (OLV) on the occurrence of subcutanous emphysema during retroperitoneal laparoscopic urologic surgery (RPLUS).Methods Twenty-seven ASA Ⅰor Ⅱ patients,aged 29-64 yr,with body mass index 19-25 kg/m2,scheduled for elective RPLUS,were randomly divided into 2 groups:two-lung ventilation (TLV) group (group Ⅰ,n =15) and OLV group (group Ⅱ,n =12).In group Ⅰ,the patients were tracheal intubated and TLV was performed.In group Ⅱ,the left-sided double lumen endobronchial tube was inserted and TLV was performed,OLV on the non-operated side was performed starting from 10-15 min before pneumoperitoneum and TLV resumed at the end of pneumoperitoneum.The end-tidal CO2 partial pressure and minute ventilation volume were measured before pneumoperitoneum (T1),at 30 and 60 min of pneumoperitoneum (T2,3),and at 30 min after the end of pneumoperitoneum (T4).The CO2 absorption capacity was calculated.The degree of pneumoderma was assessed and the occurance of pneumoderma was recorded at the end of pneumoperitoneum.Results Compared with group Ⅰ,the CO2 absorption capacity was significantly reduced,and the degree and incidence of pneumoderma were significantly decreased in group Ⅱ (P ＜ 0.05).Conclusion OLV on the non-operated side can reduce the CO2 absorption capacity,decrease the degree of subcutaneous emphysema and reduce the occurrence of subcutanous emphysema during pneumoperitoneum in patients undergoing RPLUS.

Objective To observe the influence of low protein diet with α-keto acid on kidney sclerosis and renin-angiotensin system in renal ablation rats. Methods Chronic renal failure rat model was established by renal ablation in 30 male SD rats,then the animals were randomly assigned to the following diet groups:normal protein group (NPD:18%casein protein),low protein group (LPD:6%casein protein) and supplemented low protein group (LK:5%casein protein+1%α-keto acids).Ten male SD sham-operated rats received 18%casein protein as control.All the rats were killed at the end of the 12th week.Pathologic changes were assessed by PAS staining.Ang II in homogenate and plasma were measured by radioimmunoassay and ELISA respectively.Immunohistochemistry and Western blotting were used to detect the protein expression of TGF-β1,renin and AT1R.Real-time PCR was used to detect the gene expression of renin and ATla,the main subtype of AT1 receptor. Results Body weight,total protein and serum albumin had not significant difference among the four groups(all P>0.05).Serum creatinine and proteinuria of nephrectomized rats were significantly higher compared to the control group (all P<0.05).Proteinuria of the LK group was lower than that of NPD and LPD groups (all P<0.05).Pathological results indicated fibrosis indices were significantly improved after LPD and LK intervention.Expressions of renin,Ang II and AT1R in LK group were significantly lower than those in NPD group (all P<0.05). Conclusions Low protein diet with α-keto acids supplement therapy exhibits renal protective effects of reducing urine protein excretion and improving renal fibrosis,which might be related to the attenuation of local renin-angiotensin system in activity nephrectomized rats.

Retinoblastoma(RB)is the most common intraocular malignancy of children with extremely poor prognosis. MicroRNAs are small non-coding single-stranded RNAs in eukaryotic cells, which regulate the expression of gene by mRNA degradation or translation inhibition. MicroRNAs, acting as oncogenes or tumor suppressor genes, are associated with the occurrence and development of RB directly, which is vital for the early diagnosis and clinical targeted therapy of RB. This review summarized the expression of microRNAs in RB and the related mechanism.

Objective To investigate the change of indications of emergency obstetric hysterectomy and the clinical application of intraoperative interventions. And to provide evidence for prevention of hysterectomy and improvement of obstetric quality. Methods Clinical data were collected from 97 patients who received emergency obstetric hysterectomy at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. The patients were divided into two groups by the time point of January 1st, 2009: the first group was cases treated between January 1st, 2004 and December 31st, 2008, while the second group was cases treated between January 1st, 2009 and December 31st, 2013. The clinical indicators, surgical indications, intraoperative interventions, and blood loss between the two groups were analyzed retrospectively. Results (1) Incidence:54 857 women delivered at Shengjing Hospital of China Medical University between January 1st, 2004 and December 31st, 2013. Of them, 97 patients received emergency obstetric hysterectomy, with an incidence of 0.177% (97/54 857). (2) The 17 patients delivered vaginally (18%,17/97) and 80 by caesarean section (83%,80/97). Forty-nine patients experienced repregnancy with scar uterus (51%, 49/97). About 41 patients underwent abdominal total hysterectomy (42%,41/97) and 56 received subtotal hysterectomy (58%,56/97). (3) The number of patients were comparable between the two groups (50 vs 47;P>0.05). (4) The main surgical indication was uterine inertia (45%, 44/97). The main causes of uterine inertia were excessive uterine tension (45%, 20/44) and placental abruption due to gestational hypertension (32%, 14/44). Of all the indications, 29 patients in the first group (58%, 29/50) and 15 patients in the second group (32%, 15/47) suffered from postpartum hemorrhage. Pathological placenta embedment occurred in 15 patients in the first group (30%, 15/50) and 25 patients in the second group (53%, 25/47). The incidences of postpartum hemorrhage due to uterine inertia or pathological placenta embedment were significantly different between the two groups (both P<0.05), respectively. (5) In the first group, the average preoperative blood loss was (2 900±1 900) ml, and the average intraoperative amount of infused white&red blood cells was (5.9±3.5) U, with the average operation time of (2.2 ± 1.8) hours and the average in-hospital duration of (7.8 ± 2.3) days. In the second group, the average preoperative blood loss was (3 100± 2 200) ml, and the intraoperative amount of infused white&red blood cells was (6.2± 5.2) U, with the average operation time of (2.5± 2.1) hours and the average in-hospital duration of (7.9 ± 2.9) days. There was no significant difference between the two groups in any of these indicators (P>0.05). Postpartum hemorrhage was usually treated with uterine packing in the first group, but was preferentially treated with potent uterine contraction agents, arterial ligation, uterine balloon compression or B-Lynch suture in the second group. The therapeutic effects of these new treatments were significantly better than uterine packing (P<0.05). Conclusions The incidence of emergency obstetric hysterectomy did not change significantly in the past decade. However, the indications and intraoperative interventions have changed significantly in the second five years compared with the first five years. The main surgical indications were uterine inertia and postpartum hemorrhage due to pathological placenta embedment. Therefore, strict control of caesarean section indications was important to reduce emergency obstetric hysterectomy.

Objectives:To observe the effect of metabolic intervention of anti TNF antibody on the hypermetabolism occurred in intra abdominal infection(IAI) complicated by multiple organ dysfunction syndrome(MODS). Methods:Twenty rabbits were operated on with cecal ligation plus puncture(CLP) inducing IAI and MODS and were randomly divided into two groups, one receiving the anti TNF serum raised against TNF ?(anti TNF group) at 0.5?h after CLP and another receiving the non specific serum (control group). All animals were placed in metabolic cages and maintained with intravenous infusion for the observation period of one week. Serum levels of cytokines(TNF, IL 6), hormones (cortisol, insulin, glucagon), biochemical indexes (glucose, cholesterol, triglyceride, albumin) and daily excretions of urea nitrogen (UN),creatinine (Cr) and 3 methylhistidine (3 MH) were dynamically determined for 7 days. The death of animals was also recorded. Results:Compared with the control group, the levels of serum TNF, IL 6 and cortisol were significantly decreased and the levels of insulin and glucagon were kept normal after the injection of immune serum in anti TNF group, with significant improvements of biochemical indexes and decreased excretions of UN, Cr and 3 MH in urine. The survival rate was significantly increased in the anti TNF group. Conclusions:The anti TNF antibody can attenuate the metabolic abnormalities of IAI and MODS, being of the metabolic intervention on the hypermetabolism.

Objective To analyze the correlationship of ACE I/D gene polymerphisms with the anti-hypertensive efficacy of irbesartan among essential hypertension (EH) patients in Yunnan han people.Methods One hundred EH patients hypertension were treated with irbesartan 150mg once daily for 4 weeks,and anti-hypertensive efficacy were monitored during the treatment.Results There was a significant difference between anti-hypertensive efficacy of irbesartan among different genotype groups,DD group ＞ID group ＞Ⅱ group (P ＜ 0.05) Conclusions There is different therapy responsiveness in diffenent genotypes.ACE I/D polymorphism may be an important hereditary factor that impacts the efficacy of irbesartan.

AIM:To detect the expression of basic fibroblast growth factor (bFGF) and matrix metalloprotei-nase 9 (MMP9) in nasopharyngeal carcinoma (NPC) and its correlation with clinicopathological features and prognosis of the patients.METHODS:The expression of bFGF and MMP9 was detected by the method of SP immunohistochemical staining in biopsy tissues of NPC patients.The relationship between the expression and the clinical significance was analyzed as well.RESULTS:In 289 cases of NPC patients, the positive rates of bFGF and MMP9 were 71.3% and 61.6%, respectively.Correlation analysis demonstrated that the expression rates of bFGF and MMP9 were both positively associated with N stage and clinical stage in NPC patients.The high expression rates of both bFGF and MMP9 were associated with poor overall survival and progression-free survival of NPC patients.Furthermore, the positive rate of bFGF was positively correlated with that of MMP9, and over-expression of both bFGF and MMP9 was correlated with the poorest survival outcomes in NPC patients.CONCLUSION:bFGF and MMP9 are over-expressed in NPC tissues and significantly associated with NPC recurrence and poor outcome.The combined interpretation of bFGF and MMP9 expression levels leads to refinement of the risks for the NPC patients and could be chosen as the prognostic biomarkers.

OBJECTIVETo investigate the expressions of the stem cell antigen-1 (Sca-1), Mucin1 (Muc1) and CD24 in quiescent mammary glands of female rats.

METHODSThe expressions of CD24 and Sca-1 were detected in 6- and 9-week-old female rat mammary gland by Western blotting. Sections (4 microm) of 6- and 9-week-old female SD rat mammary gland were prepared to observe the expressions of Sca-1, Muc1 and CD24 by immunohistochemical labeling and immunofluorescence labeling.

RESULTSCD24 and Sca-1 in the mammary glands were expressed at lower level in 6-week-old female rats than in 9-week-old female rats. Sca-1 expression was detected in the mammary gland ductus, branching ductus, and areas surrounding the gland alveolus; CD24 was expressed in the mammary gland branching ductus and fat pads, and also the regions surrounding the gland alveolus. Muc1 expression was localized in the mammary gland ductus and branching ductus.

CONCLUSIONSSca-1-, CD24- and Muc1-positive cells may represent mammary gland progenitor cells, mammary gland stem cells, and mammary gland mature epithelium cells, respectively. This study provides some morphological evidences for identifying these cells, but they still need further verifications in cellular transplantation experiments.
