Parathyroid hormone-related protein (PTHrP) and its receptor type 1 (PTH1 R) are extensively expressed in the kidney,where they are able to modulate renal function.Animal and human studies have shown that PTHrP acts as an important mediator of diabetic renal cell hypertrophy by a meehanism which involves the modulation of cell cycle regulatory proteins and TGF-β1.Furthermore,angiotensin Ⅱ (Ang Ⅱ) appears to be responsible for PTHrP upregulation in these conditions.These findings provide novel insights into the well-known protective effects of Ang Ⅱ antagonists in renal diseases,paving the wav for new therapeutic approaches.

With the development of surgical techniques, the use of nipple-areola complex (NAC)-sparing mastectomy (NSM) has been increasing. Except for oncologic safety, the aesthetic outcome of surgery is greatly concerned by clinicians and patients. So far, there has been no consensus on the incision of NSM. This article reviewed the literature so as to provide some evidence for the selection of NSM incision.

Mesenchymal stem cells (MSCs) have been found to home to tissues/organs with irflammation,the sites of growing tumors,as well as to participate in the formation of the tumor micro-environment,suggesting that MSCs play important roles in tumor growth and metastasis.To study the roles and mechanisms of MSCs in tumor growth and metastasis will provide new insights into tumorigenesis and tumor target therapy.

Objective To explore the influence of blocking B7/CD28 co-stimulatory pathway by RNA interference on the rejection response in mice heterogeneous heart transplantation and its mecha- nism.Methods siRNA of which sequence specified to CD80 and CD86mRNA was synthesized in vitro respectively and transfected into donor derived myeloid dendritic cells (DCs).The expression levels of CD80 and CD86 mRNA and surface antigen CD80,CD86 were assayed by semi-quantitative reverse transcription polymerase chain reaction and flow cytometry before and after CD80siRNA and CD86siRNA transfection.Seven days prior to heterogeneous heart transplantation in mice,DCs modi- fied by siRNA were transfused into recipients intraveneously (DC interference group).At the same time,group of allograft transplantation,cyclosporine A (CsA)-treated (CsA injected subcutaneously postoperatively,5 mg.kg~(-1)?d~(-1)) group,group of isograft transplantation,and non-interference DC group (transfusion of non-interfered DCs pre-transplanting) were assigned.The graft survivals were individually recorded and the graft rejection grading was pathologically evaluated.Interleukin 2 (IL- 2),interferon?(IFN-?),and IL-10 mRNA expression levels in grafts tissue were determined.Results After siRNA transfected into DC,the expression levels of CD80 and CD86 mRNA were down- regulated significantly and the the antigen CD80~+ and CD86~+ reduced from 84%,67% to 35% and 30% respectively.As compared with groups of allograft and non-interference DC,survival of the grafts was significantly longer in DC interference group (P＜0.01),pathological grade of rejection significantly lower (P＜0.01),IL-2 and IFN-?mRNA expression levels lower,and IL-10 mRNA ex- pression levels higher in grafts tissue (P＜0.01).Conclusion Knocking down the molecule B7 expres- sion level in donor-derived myeloid DCs through RNAi,which could block B7/CD28 co-stimulatory pathway,could exhibit inhibitive effect on rejection response in mice heart transplantation.The mechanism might be due to induction of T lymphocyte anergy and Th cell differentiation deviating to T_H2.

Objective To summarize the nursing key points in nursing ovarian cancer patients with early postoperative inflammatory intestinal obstruction after non-surgical treatment value. Method The nursing data of 32 ovarian cancer patients with early postoperative inflammatory intestinal obstruction in our department in January 2010 to October 2016 were retrospectively analyzed. Results About 32 patients were treated with non-surgical treatment, cure time within 2~30d, averaged (7.80 ±5.98)d. No intestinal obstruction happened after resuming to normal exhaustion, defecation and dieting. Conclusion Such nursing measures as psychological nursing, gastrointestinal decompression nursing, nutrition support nursing and auxiliary therapy like promoting peristalsis recovery are key to the increase of cure rate of early postoperative inflammatory intestinal obstruction.

Objective To compare the disadvantages and advantages of open thyroid surgery when using the harmonic scalpel (HS) vs conventional hemostasis (CH). MethodsOne hundred and fifty-one patients and 70 patients underwent thyroid surgery with HS or CH respectively. The tumor diameter, incisional length, the total operative time, thyroidectomy time, intraoperative bleeding volume, postoperative drainage volume and surgical complications were compared. The incisional length and the surgical complications in and after learning curve with harmonic scalpel were compared. ResultsThere was no significant difference between the HS and CH group at baseline. Incisional length, total operative time, thyroidectomy time, intraoperative bleeding volume and postoperative drainage volume in HS group were significantly lower than those of CH group (P0.05); the incisional length after learning curve was shorter than that in learning curve in HS group (P

Objective To assess the value and usage of real-time monitoring of the recurrent laryngeal nerve (RLN) during thyroid reoperation by RLN monitor. Methods One hundred and one patients were under general anesthesia and thyroidectomy. NIM-Response electromyographic (EMG) monitor system was used for assistant of dissection,exposure and protection of the RLN during the surgical procedures. Results There were 192 RLN were exposed during the surgeries in all 101 patients. The unilateral RLN injured in 10 patients was not specially explored the same side nerve. Among them 190 nerves were confirmed intact,the rest 2 nerves were resected because of tumor involving. Conclusion s NIM-Response electromyographic monitor system is sensitive and accurate for preserving the integrity of RLN during the thyroid reoperations. It is valuable for protecting RLN against iatrogenic injury. This system deserves general utilization for thyroid surgery,especially reoperation.

Objective:To investigate the effect of ulinastatin(UTI) on the changes of IL-6,TNF-?,IL-10 and IL-4 expression during perioperative period of surgical correction of adolescent idiopathic scoliosis(AIS).Methods: Twenty patients with AISⅠ-Ⅱ scheduled to receive surgical correction of spinal deformities were equally randomized into 2 groups-UTI group and control group.Patients in UTI group received intravenous infusion of 10 000 U/kg UTI with 250 ml normal saline just before operation and every 4 h thereafter if necessary;patients in control group received same amount of normal saline.ECG,CVP,SpO_(2)and P_(ET)CO_(2) were continously monitored during operation in both group.Mean arteral pressure(MAP) was maintained at(60?5) mmHg(1 mmHg=0.133 kPa).Venous blood samples were collected immediately before induction of anaesthesia(T_(1)),10 min after induction(T_(2)),1 h after UTI administration(T_(3)),30 min after extubation(T_(4)) and 24 h postoperatively(T_(5)).The plasma levels of IL-6,TNF-?,IL-10 and IL-4 were measured by enzyme-linked immunosorbent assay(ELISA),and their mRNA expression was assayed by real-time quantitative reverse transcription polymerase chain reaction.Results: At T_(3),T_(4) and T_(5),plasma levels of IL-6 and TNF-? and their mRNA copies in control group were significantly higher than that at T_1(P
