Objective To investigate the depressive disorders in patients with respiratory diseases and analyze the countermeasures against it to provide reference for improving clinical treatment compliance. Methods 80 cases was selected according to the screening and exclusion criteria from 262 patients with respiratory diseases from January, 2014 to December, 2015. Then divided them randomly into treatment group and control group. The SDS and SAS show no statistical signiifcance before treatment (P>0.05). The control group with clinical disease symptomatic and supportive treatment, the treatment group combined with anti-anxiety treatment on the basis of clinical symptomatic and supportive group. Then compare the SDS, SAS and dyspnea improvement between the two groups before and after treatment. Results The SDS and SAS scores showed no significant difference before treatment (P>0.05). While after treatment, the SDS and SAS scores in treatment group were signiifcantly lower, and lower than the control group, the difference was statistically signiifcant (P<0.05). The condition of dyspnea of the two groups show no difference before treatment (P>0.05). After treatment, the condition of dyspnea improved greater in treatment group than the control group, the difference was statistically signiifcant (P<0.05). Conclusions Because the respiratory disease of patients suffered leads to psychological burden, negative emotional depression anxiety appears not well with the clinical work, by using Deanxit improve patient confidence and compliance, there is a certain positive to improve the clinical symptoms with good clinical value.

Methods Perforating branch flap (muscle branch) of medial vastus muscle was designed by using the surface projection of the medial vastus muscle artery as flap anxial line and the given point of direct cutaneous artery as flap center to repair skin and soft tissue defects of the knee in seven patients.Results All flaps survived well with primary healing in all patients, with one stage healing. After a follow-up for 1-18 months, all flaps turned out to be with good texture and satisfactory appearance and function of the flaps. Conclusion The surgery of perforating branch flap of medial vastus muscle is simple,safe and easy handling and provides a new feasible surgical procedure to repair skin and soft tissue defects of medial femur and around the knee.

Objective To provide anatomical basis for lateral antebrachial neurocutaneous flap pedi-cled with inferior cubital artery perforator in repairing tissue defects around elbow joint. Methods Thirty embalmed upper limbs of adult cadavers perfused with red latex were used for this study, and followings were observed:①The course and distribution of lateral antebrachial cutaneous nerve; ②Anastomoses between inferior cubital artery and nutrient vessels of lateral antebrachial cutaneous nerve. Mimic operation was performed on other side of fresh specimen. Results ①The main trunk of lateral antebrachial cutaneous nerve (LACN) lined in the radial forearm and distributed in the 1/3 region of lateral forearm. ①The nutritional vessels of the flap were plurisegmental and polyphyletic. The inferior cubital artery which was relatively constant reached to skin through "V"-shaped peak formed by communicating branches of cephalic vein and deep venous system. They also gave off large number of small veins, which closely aligned with perineural branches and neural stem vascular chain of lateral antebrachial cutaneous nerve. Conclusion The lateral antebrachial neurocutaneos flap pedicled with inferior cubital artery perforator can be formed to repaire tissue defects around elbow joint.

AIM:Mesenchymal cells migrating towards fracture site and differentiating into chondrocytes and osteoblasts is the key process during fracture healing. This article is aimed to observe the changes of the expression of bone morphogenetic protein(BMP)-2 in the early stage of tibia fracture in osteoporotic rats so as to evaluate the reason of delayed fracture healing in osteoporotic rats. METHODS:The experiment was conducted at the Key Laboratory for Oral Biomedical Engineering of Ministry of Education from August 2005 to October 2006. ①Sixty-four 6-month-old female SD rats were randomly divided into ovariectomized(OVX) group and control group with 32 in each group. ②The rats in the OVX group underwent ovariectomy to establish type Ⅰ osteoporotic models. A small quantity of fat tissues was removed in the control group. Three months later,standardized tibia fracture was introduced. ③Eight rats were selected at days 7,14,21 and 28 after operation in the two groups. Some soft tissues around tibia and broken ends of fractured bone,bony callus,cortical bone and medullary canal were collected and treated with histological analysis,immunohistochemical staining,semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR),respectively. RESULTS:①Histological analysis showed membrane bone formation and endochondral bone. A mass of chondrocytes appeared in bony callus of the OVX group at days 21 and 28 after operation. ②The results of immunohistochemical staining showed that mean absorbance(A) of BMP-2 was higher in the control group than the OVX group at days 7 and 14,but lower at day 21. ③The findings of RT-PCR revealed that BMP 2 level was higher in the control group than the OVX group at day 7,but lower at day 14. CONCLUSION:BMP-2 plays a key role in the early phase of bone callus formation during fracture healing. The declined and delayed expression of BMP-2 in osteoporotic rats may be an important reason for delayed fracture healing in osteoporotic rats.

Objective The clinical features of elderly patients with severe acute pancreatitis (SAP) were atypical and these patients were often misdiagnosed as having paralytic ileus. The clinical presentations of elderly patients with SAP whose first diagnosis as paralytic ileus were analyzed. Methods 18 patients of elderly SAP who were misdiagnosed as having paralytic ileus were included and the clinical data were compared with 58 elderly patients with SAP. Results Among the misdiagnosis group, the first symptom onset were fleus, abdominal distension, vomiting, constipation, abdominal pain, diarrhea for 5, 4, 3, 3, 2, 1 case, respectively. Among SAP group, the first symptoms onset were 2, 31, 9, 3, 11, 2 cases, respectively. For misdiagnosis group, 13 cases were correctly diagnosed by CT scan, 3 cases by ultrasound and 2 cases by serum amylase test. For SAP group, 32, 15, 11 cases were diagnosed by CT scan, ultrasound and serum amylase, respectively (P < 0.05). 4 and 13 patients died in misdiagnosis and SAP group, respectively; among these 13 patients, 10 were female and 3 were male. Conclusions The elderly patients with paralytic ileus should consider the possibility of SAP, and CT scan was valuable for correct diagnosis.
