Clinical value of serum BNP,TNF-α,MMP-9 and IL-6 detection in CHF patients with different heart function grades / 国际检验医学杂志

Objective To discuss the clinical value of serum brain natriuretic peptide (BNP) ,tumor necrosis factor‐α(TNF‐α) , matrix metalloproteinase‐9(MMP‐9) and interleukin‐6(IL‐6) detection in chronic heart failure (CHF) patients with different heart function grades and their correlation with CHF .Methods Totally 67 cases of CHF in our hospital from Jan .2013 to Jun .2015 were selected as the observation group and the NYHA classification was performed :gradeⅠ in 15 cases ,gradeⅡ in 21 cases ,gradeⅢ in 23 cases and grade Ⅳ in 9 cases .Other 30 individuals undergoing the healthy physical examination were chosen as the control group at the same period .The venous blood samples were collected for detecting serum BNP ,TNF‐α,MMP‐9 and IL‐6 .LVEDD ,LVESD and LVEF were measured by echocardiography .Then the obtained data were analyzed by using the SPSS 21 .0 software .Results The serum BNP ,TNF‐α,MMP‐9 and IL‐6 levels in the observation group and various cardiac function groups were higher ,the differences between them were statistically significant (P< 0 .05);LVEF in the observation group and various cardiac function groups were obviously declined ,while LVEDD and LVESD were obviously increased ,the differences were statistically significant (P<0 .05) .The linear regression was adopted to analyze the correlation between serum BNP ,TNF‐α,MMP‐9 and IL‐6 with the left ventricular echocardiographic parameters in the CHF patients ,the results showed that serum BNP ,TNF‐α,MMP‐9 and IL‐6 levels were negatively correlated with LVEF (P<0 .05) ,while positively correlated with LVEDD and LVESD (P<0 .05) .Conclusion The serum BNP ,TNF‐α,MMP‐9 and IL‐6 levels are the good indexes for diagnosing CHF ,moreover can accurately reflect different heart function status in the CHF patients with different cardiac function grades ,which are closely related to the occurrence and de‐velopment process of CHF .

The anatomy study of the frontal beak approach of Draf II b frontal sinusotomy / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the possibility and anatomy landmark of the frontal beak approach of endoscopic frontal sinusotomy to the frontal sinus lesions.@*METHOD@#(1)Twenty cases of frozen cadaveric head underwent spiral computed tomography scans. Then data were transferred into the Mimics image workstation to reorganize CT images in the coronal, sagittal, and axial planes. The anatomic parameters related to surgical approach points were measured, such as the distance between vertical plate of the middle turbinate and lamina papyracea and the thickness of the frontal beak. (2) 3D visual model of the frontal cell and the drainage way of the frontal sinus was produced with the application of Sinuses Trachea I software. (3)The endoscopic frontal sinus surgery were performed on 20 cases of subjects (objects)to find out the anatomy landmarks of the frontal beak approach, measure the parameters such as the distance between middle turbinate and lamina papyracea, and evaluate the potential surgical complications during operation.@*RESULT@#(1)The frontal beak is a white bony arcs located at the attachment point of middle turbinate front inserted to the skull base. Its position was relatively constant, before frontal sinus above. (2)The distance between the middle turbinate vertical plate and lamina papyracea was (7. 61 ± 1. 34) mm. The thickness of the frontal beak in surgical approach was (3. 27 ± 0. 91) mm. (3) 3D visual structure of the frontal sinus and its ventilation pathway: the shape of unilateral frontal sinus looked like the cone, which was transited by the drainage pathway of the frontal sinus. The front part of the frontal sinus ostium is surrounded by the frontal beak. The upper part the frontal beak connected to the floor of the frontal sinus. (4) Frontal beak can be used as an landmark of frontal beak approach in the endoscopic frontal sinus surgery. But the lateral view of frontal sinus still was limited in the operation.@*CONCLUSION@#The endoscopic frontal sinus surgery with the approach of the frontal beak is easy to operate and learn. In this area between the double "L", the operation is safe.

TNF-α Expression in the Peritoneum of Curcumine Pretreated Acute Peritonitis Rat / 中国医科大学学报

Objective To investigate the effects of curcumine treatment on the expression of TNF-α in the peritoneum of acute peritonitis rats. Methods The rats were intrapertoneally injected Staphylococcus epidemidis (S.epidermidis) for the mixlelization of acute peritonitis. After a survival time of 3,6,12,24 and 48 hours,TNF-α expression in the peritoneum was detected by Western blot and RT-PCR in the rats of curcumin treatment group and non-curcumin treatment group. Results TNF-a expression showed time-dependent increase at 6,12,24 hours after the infection in the non-curcumin treatment group. In curcumin treatment group,TNF-α expression decreased at 6,12,24 hours after infection compared to non-curcumin treatment group. Conclusion Curcumin may be a protective agent in acute peri-tonitis induced by S.epidermidis.

Report on skin-sparing mastectomy with immediate breast reconstruction in 15 cases / 中国组织工程研究

BACKGROUND: Recently the prevalence rate of mass in mammary gland increases significantly than before. To use which kind of technology is not only related with the post-operation recurrence, but also related with the reconstruction of their confidence. Therefore, how to reduce the trauma physically and psychologically in patients to the maximal degree has become the chief factor to choose technology by surgeons.OBJECTIVE: To observe the effects of transverse rectus abdominis musculocutaneous (TRAM) flap, latissimus dorsi musculocutaneous flap with breast prothesis, local flap and simple breast prothesis after skin-sparing mastectomy with immediate breast reconstruction.DESIGN: Case analysis.SETTING: Department of Plastic Surgery, Shenzhen People's Hospital,Second Clinical Medical College of Jinan University.PARTICIPANTS: A total of 15 ductal carcinoma in situ (DCIS) and huge breast benign tumor patients were enrolled into Shenzhen People's Hospital between October 1997 and May 2004, aged from 20 to 46 years. They all got disease in single breast, and 8 of them had preoperative diagnosis of DCIS, T1N0M0 and 7 of them had huge breast benign tumor. Operation program was informed to the patients before operation so as to gain their agreement.METHODS: Skin-sparing mastectomy was performed with circular shape incision at areola and using TRAM flap, latissimus dorsi musculocutaneous flap with breast prothesis, local flap and simple breast prothesis to fill breast. Slight skin of musculo-cutaneous flap could compensate the nipple and areola when performing reconstruction. At the reoperation, nipple was made at the transferred flap.MAIN OUTCOME MEASURES: To observe the patients with or without recurrence or transfer after operation and local healing of wound.RESULTS: With the cooperation of general surgeons the operation was done in 15 cases and 14 cases of them were followed up for more than 1 year. The reconstructed breasts were with good symmetry with the opposite one, normal skin sensation, natural shape and inconspicuous scar.CONCLUSION: This is an excellent alternative method for mastectomy and breast reconstruction based on the avoidance of recurrence of breast cancer in severe operation.
