Citing the IT development of the General Hospital of Nanjing Military Region at Fuzhou as an example, the authors point out that emphasizing the role of the people and doing a good job of talent planning and cultivation is the key to the IT development of a hospital. They argue that a hospital must have leaders and managers that stress the IT development of the hospital; it must have a team of people with high IT expertise; it must have a large number of staff very familiar with the operation of the computer; and it must be able to integrate its human resources and give play to the overall efficiency.

Objective To study the effect of long-term salmon calcitonin on bone mineral density (BMD), bone metabolism biochemical indicators and subjective score of bone pain in maintenance hemedialysis (MHD) patients with osteopenia. Methods Thirty-four MHD patients diagnosed as osteopenia by dual-energy X-ray absorptiometry (DXEA) were enrolled in this study. All the patients were treated with hypodermic injection of salmon calcitonin (50 U, thrice a week) for 12 months. The detecting parameters were as follows: BMD with DEXA in lumbar spine (L1-L4), femoral neck, troch, inter, and Ward's triangle before and after the study;serum bone metabolism biochemical indicators before and 6 and 12 months after the study;subjective scores of bone pain before and 1, 6, and 12 months after the study. Results Thirty-two patients were followed-up successfully. As compared to BMD parameters before study, the total T-score (-1.98± 2.20 vs 1.26±1.88, P=0.009) and total Z-score (-0.90±2.15 vs 0.08±2.05, P=0.002) of lumbar spine, the total T-score (-1.72±1.53 vs 1.06±1.58, P=0.016) and totle Z-score (-0.66±0.80 vs 0.08±1.08, P=0.029) of hip, the T-score of L3 (-2.02±2.51 vs 1.24±2.02, P=0.033), the Z-score of L2 (-0.44±1.82 vs 0.06±1.63, P=0.016), the Z-score of femoral troch (-0.65±1.11 vs 0.48±1.12, P=0.034) and the Z-score of inter (-0.58±0.94 vs 0.02±1.12, P=0.006) were increased significantly after study. But there were no significant differences in other examined regions and serum biochemical parameters. The subjective scores of bone pain were decreased rapidly for 41.7% after 1 month (P<0.01) and 76.6% after 6 months (P<0.01). The subjective score of bone pain after 12 months was similar to 6 months. The side effects of salmon calcitonin included nausea and vomitting in 5 cases (14.71%, 5/34), dizziness, blushing and flustered in 1 case respectively (3.13%,1/32). Conclusions Long-term hypodermic injection of salmon calcitonin can improve BMD and bone pain for MHD patients with osteopenia but has no significant effect on serum bone metabolism biochemical indicators. Salmon calcitonin is safe for MHD patients with seldom side effects, such as nausea and vomitting.

Computer based patient records(CPR) are an inevitable trend in the process of building digital hospitals. The authors offer an analysis of the implications and functions of CPR, arguing that in essence computer based patient records are first of all "records", which must carry all the attributes of traditional records and that their "electronic" form of expression and means of implementation are only of secondary importance. The following viewpoints are set forth: ①management of CPR data by means of databases rather than the text mode; ②adoption of authorization by doctors and the scheme of security control; ③implementation of the supplementary subensemble scheme.

Objective:
To investigate the clinical effects of free superficial femoral artery femoral triangle perforator flap in the repair of skin and soft tissue defects in extremities.
Methods:
From January 2016 to November 2017, 14 patients (9 males and 5 females, aged 19 to 54 years) with skin and soft tissue defects in extremities accompanied with tendon and bone exposure were admitted to our unit. The size of skin and soft tissue defects after debridement ranged from 7 cm×3 cm to 10 cm×7 cm. The defects were repaired with free superficial femoral artery femoral triangle perforator flaps, with size ranging from 13.0 cm×2.0 cm to 20.0 cm×4.5 cm. The medial femoral cutaneous nerve was applied to the flap. The perforator flap was grafted onto the medial femoral cutaneous nerve in 6 patients. The donor sites were sutured directly. The survival of flaps and the follow-up of patients were observed.
Results:
All flaps of 14 patients survived successfully. The recipient sites and donor sites were healed completely in 13 patients, and 1 patient with partial skin necrosis at the edge of flap was healed after treatment. All patients were followed up for 6 months to 1 year after the operation. The flaps were in good shape, with nearly normal color and soft texture and no cicatrix contracture deformity. The flaps recovered protective sense in 6 patients who had medial femoral cutaneous nerve grafting, and the sensory recovery of the flap was slightly worse in the remaining 8 patients. There was no significant complications on the appearance and walking of the donor thigh in 14 patients, only a linear scar was left on the inner thigh, and no numbness was felt in the donor sites of patients.
Conclusions
The free superficial femoral artery femoral triangle perforator flap is an ideal therapy for repairing skin and soft tissue defects in extremities.

Autologous cancer vaccine that stimulates tumor-specific immune responses for personalized immunotherapy holds great potential for tumor therapy. However, its efficacy is still suboptimal due to the immunosuppressive tumor microenvironment (ITM). Here, we report a new type of bacteria-based autologous cancer vaccine by employing calcium carbonate (CaCO3) biomineralized Salmonella (Sal) as an in-situ cancer vaccine producer and systematical ITM regulator. CaCO3 can be facilely coated on the Sal surface with calcium ionophore A23187 co-loading, and such biomineralization did not affect the bioactivities of the bacteria. Upon intratumoral accumulation, the CaCO3 shell was decomposed at an acidic microenvironment to attenuate tumor acidity, accompanied by the release of Sal and Ca2+/A23187. Specifically, Sal served as a cancer vaccine producer by inducing cancer cells' immunogenic cell death (ICD) and promoting the gap junction formation between tumor cells and dendritic cells (DCs) to promote antigen presentation. Ca2+, on the other hand, was internalized into various types of immune cells with the aid of A23187 and synergized with Sal to systematically regulate the immune system, including DCs maturation, macrophages polarization, and T cells activation. As a result, such bio-vaccine achieved remarkable efficacy against both primary and metastatic tumors by eliciting potent anti-tumor immunity with full biocompatibility. This work demonstrated the potential of bioengineered bacteria as bio-active vaccines for enhanced tumor immunotherapy.

Objective:To analyze characteristics and trends of histopathological diagnosis of adult renal biopsy in Beijing from 2008 to 2020.Methods:A total of 4 652 cases of adult renal biopsy were collected from three hospitals in Beijing between 2008 and 2020. The patients were divided into three age groups: 18-40 years, 40-65 years and≥ 65 years; and also divided into three period: 2008-2011, 2012-2015, and 2016-2020. The pathological characteristics and changes of renal biopsy were analyzed in three age groups at different periods.Results:Among 4 652 cases primary glomerular disease accounted for 81.8%, the membranous nephropathy (MN, 32.4%, 1 509/4 652), IgA nephropathy (IgAN, 29.2%, 1 356/4 652) and minor glomerular abnormalities (MGA, 11.3%, 526/4 652) were the top three pathological types. The overall proportion of MN and diabetic nephropathy (DN) increased from 20.3% and 2.3% in 2008-2011 to 37.3% and 10.1% in 2016-2020) (χ2=99.9 and 96.1, both P<0.01), respectively. For age group 18-40 years, the MN and DN increased from 11.2% and 1.6% in 2008-2011 to 24.7% and 5.5% in 2016-2020 (χ2=32.7 and 20.7, both P<0.01), respectively. For age group 40-65 years the MN and DN increased from 26.6% and 3.2% in 2008-2011 to 41.5% and 13.1% in 2016-2020 (χ2=39.1 and 57.3, both P<0.01), respectively. For age group≥65 years the MN was the most common pathological type in the three periods, fluctuating between 41.3% and 55.0% (χ2=5.2, P=0.08); and DN increased from 0(0/63) in 2008-2011 to 7.5%(22/292) in 2016-2020 (χ2=8.1, P=0.02). Conclusion:The renal biopsy data show that membranous nephropathy and diabetic nephropathy are the most common primary and secondary adult glomerular diseases in Beijing recently.
