The paper described the framework for the hospital to compile its "12th Five-year Plan", including the introduction, status quo analysis, planned objectives, and implementation strategy.The introduction in which needs to pinpoint the strategic objectives of the hospital in five years; the status quo analysis to cover the strengths, weakness, and threats and opportunities faced by the hospital in terms of both internal and external conditions; the planned objectives need to clarify the vision,mission, general goals and targets; and the specific strategies in the end. A scientific and feasible development plan can only be compiled based on conditions of the hospital, scientific rules and framework.

Objective To study the biological characteristics of platelet-derived growth factor A and human beta defensin 2 (hPDGF-A/hBD2) gene-modified rat bone marrow mesenchymal stem cells (BMSCs). Methods By using liposome transfection technique, recombinant adenovirus vector expressing hPDGF-A/hBD2 (Adv-hPDGF-A-IRES-hBD2) labeled with GFP was transfected into 293T cells for virus packaging and amplification. BMSCs were isolated, cultured and infected by adenovirus-containing supernatant. The exogenous gene-modified BMSCs were comprehensively studied on their biological features, in terms of morphology, cell growth curve, cell cycle, and adipogenic, osteogenic and myogenic differentiation ability. Results hPDGF-A-IRES-hBD2 gene-modified BMSCs did not show obvious changes in cell viability, proliferation, cell cycle distribution or cell differentiation. Conclusion BMSCs were not only good carriers for exogenous hPDGF-A and hBD2 genes but also seed cells for cell therapy even after hPDGF-A/hBD2 modification.

Objective To explore the feasibility of mobilization circulating MSCs by G-CSF and observe the repairing effect of G-CSF mobilization in severe mouse traumatic brain injury(TBI) model.Methods MSCs-derived bone marrow and peripheral blood(PB) were cultured and its CFU-F were counted after mobilization by G-CSF.At 2,24,48,96,120,144,192,264,336 h after severe TBI in mice was establish,the neurobehavior of mice was measured by neurological examination and motor functional test,and mortality rate and pathologic changes were analyzed.Results MSCs-derived PB were successfully cultured.The CFU-F of mobilization group increased significantly than that of control group(P

Objective To further determine their possible synergistic effect on accelerating wound healing, adenovirus vector containing recombinant human hPDGF-A and hBD2 genes was constructed and the expression of exogenous genes in transformed mesenchymal stem cells derived from rat bone marrow was observed. Methods By putting IRES in the middle of hPDGF-A and hBD2, these two genes were expected to be expressed individually. The shuttle vector was named as pAdTrack-hPDGF-A-IRES2-hBD2, which homologously recombinated with Adeasy-1 in BJ5183 cells and formed the mammalian expression vector pAdeasy-hPDGF-A-IRES2-hBD2. Furthermore, the recombinant vector was packaged in 293 cells into infectious recombinant adenovirus, which were used to infect BMSCs. The expression of hPDGF-A and hBD2 in BMSCs was detected by RT-PCR. Results We successfully constructed recombinant adenovirus vector that simultaneously expressed hPDGF-A and hBD2. The expressions of hPDGF-A and hBD2 were confirmed by RT-PCR on transformed BMSCs. Conclusion The established BMSCs that overexpressed hPDGF-A and hBD2 provide a new strategy of combining cell therapy and gene therapy to promote wound healing, especially the chronic one.

Objective To explore the expression of HCCR, pERK and pELK1 in gastric cancer tissue and para-carci-noma tissue, and to explove its correlations. Methods In 60 human gastric cancers and their corresponding paraneo-plastic tissuses,the expression of HCCR, pERK and pELK1 were detected by immunohistochemistry. Results The ex-pression of HCCR was 75.0%(45/60), pERK, and pELK1 were 73.3%(44/60) and 71.7%(43/60), respectively, and the expression of proteins in gastric tumor were higher than that in paraneoplastic tissues (P<0.05). Conclusion The HCCR, pERK and pELK1 are higher expressed in tumor tissues, availably as a auxiliary index for clinical immunohis-tochemistry in gastric cancer.

Objective: To evaluate the safety and efficacy of tabularized urethral plate disassembly for epispadias repair in infant. Methods: From January 2016 to September 2018, 10 boys aged between 18 to 36 months old with mishaft epispadias were included. The main complaint was that the urethral opening was found on the dorsal side of the penis. Preoperative cystography revealed that 3 of them had unilateral vesicoureteral reflux (Grade Ⅰ), and white blood cells in routine urinary in all 10 patients were negative. Physical examination: the penis is short and flat, the width is 17-25 mm, average is 20.7 mm, the penis curvature is 15°-30°, average is 21.5°, and the urethral opening located on the dorsal side of the penis. The anesthesia method was selected for tracheal intubation, intravenous anesthesia combined with caudal anesthesia, and the surgical position was supine position. The surgical method: one stage of tabularized urethral plate disassembly urethroplasty: during the operation, the penile curve was corrected by free urethral plate and penile degloving. Two of them were unsatisfied with the correction of the curvature, and the ventral tunica folded was applicate. To avoid urethral plate ischemia, attention should pay to blood supply protection. The two corpus cavernosum are separated in the root, and the urethra is completely displaced to the ventral side of the cavernous body. The ventral side of the urethral under glans is shaped into a fissured that conforms to the anatomy. The prognosis and surgical choice of the midshaft epispadias were discussed combined with literature. Result: The operation time was 130-200 min with an average of 157 mins. Intraoperative hemorrhage 5-30 ml, average is 16 ml, 1 case of glans skin was black one day after surgery, with enhanced dressing change. After 1 month, the glans was local atrophy and scar formation. No skin incision infection case. After discharge from the hospital, the follow up through the internet and outpatients for 3-40 months, average is 21 months, 2 cases with urethral fistula, more surgery to repair the fistula successfully after 6 months. The penile curvature was corrected in 8 cases, and the residual curvature of 2 cases was about 10-15°, which was temporarily observed. Patients with unilateral vesicoureteral reflux preoperatively, they still suffered from vesicoureteral reflux in the 6-12 months regular review after surgery without any intervention due to white blood cell was negative in urine routine. All cases had urinary patency and no cases with urethral stricture. Conclusion Tubularized urethral plate disassembly is a effective and simple procedure that can correct the midshaft epispadias in infant.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.
