Objective To observe the efficacy of comprehensive strategies in treating diabetic foot.Methods Thirty five cases with diabetic foot were treated by comprehensive strategies,including antiinfection,strict blood sugar control,vasodilatation,improvement of microcirculation,never nutrition,debridement and supportive care,etc.Results Among the 35 patients with diabetic foot,24 were recovered satisfactorily,7 cases were recovered with improvement,2 cases underwent amputation and 2 cases gave up further treatment.Conclusion Diabetic foot can be treated by comprehensive measures satisfactorily,with improved cure rate and low amputation rate.

The serum suppressive activity on PHA-induced lymphocyte transformation of healthy individuals was evaluated in 76 serum samples from 55 patients with systemic lupus erythematousus(SLE).The serum suppressive activity seemed well correlated with the activity of SLE. The highest levels of suppressive rate (55.02+29.62％) and positive rate(88.33％)were found in patients with active disease. Once disease improved, both suppressive rate and positive rate were reduced (22.17?51.28％ and 51.85％ respectively), when the patients entered into stationary stage, the serum suppressive activity were not observed. The correlation between suppressive activity and lymphocyte transformation test, E-rosett inhibition factor, the levels of serum CIC, IgG, IgA, IgM. C3 and ANA titers were analysed. Stepwise discriminant analysis indicated that the serum suppressive activity was more closely related to disease activity than other immunological indexes. The nature of suppressive factor was discussed.

The paper analyzes the status of hospital websites construction in Jiangau province, which would provide useful evidence for further development. Surfing on the hospital wehaites covering both third and second class hospital in Jiangsu province, it reveals that the websites of third-class hospital are much better than the second-class ones. However, both of them have problems on contents, domain names and interactive parts. The paper suggests that we should constantly explore the methods and ways to solve those existing prob-lems, focus on strengthening informafization construction in hospital and play its advantages.

Fourteen critical patients were treated by total parenteral nutrition(TPN) or en- teral nutrition(EN) and good results were achieved.Among the1 4patients,1 0 cases were suffered from MSOF.The results suggest thatnutritional support is very im- portant for the critical patients,especially for their rehabilitation and prognosis.The use of TPN is not limited by the gastroin- testinal function.TPN should be sellected preferably when a patient is critical and se- rious.EN should be used when gastroin- testinal function have recovered in order to reduce the translocation of bacteria and en- dotoxin in the gut and decrease gastroin- testinal bleeding.

Objective To investigate the effects of titanium nitride(TiN) coating on corrosion resistance of dental Co-Cr alloy in the simulated oral environment. Methods The Co-Cr alloy commonly used was casted with specimen sized of 10 mm× 10 mm×3 mm. Then the specimen was coated with a thickness of 2.5 μm TiN coating on the surface by multi-arc physical vapor deposition. The Tafel polarization curves of the specimen before and after coating titanium nitride in artificial saliva were measured by electrochemical station. Results From the Tafel polarization curves, the specimen after coating TiN showed that both anodic polarization curve and cathodal polarization curve were fiat, natural corrosion potential moved to the positive way, and passivation interval got longer. From the annular anodic polarization curves, the specimen after coating TiN had almost no "delay area". Conclusion TiN coating can improve corrosion resistance of Co-Cr alloy.

Recent studies about stem cells show that the formation of portal vein tumor thrombus(PVTT)is closely relative to the metastasis of liver cancer stem cells induced by portal vein microenvironment.Liver cancer stem cells first detach from the primary tumor,extravasate to extracellular matrix,stimulate angiogenesis or intravasate and migrate through the systemic circulation,evade host defense mechanisms,migrate to specific blood vessel sites through chemo-taxis and attach to blood vessel wall,then extravasate through blood vessel and home to specific microenvironment and to form PVTT.

Osteoporosis is a disease that threatens human health seriously.Orthopedics plays a very important role in the prevention and treatment of osteoporosis.Teachers of orthopedic department should pay more attention to the teaching of osteoporosis and establish specialized courses to make medical students to learn more about osteoporosis in clinical teaching process

[Objective]To propose new strategies on enhancing effectiveness of accidental damage and pioneer new realms for disease prevention strategy, this paper emphasized on analyzing the way and function of disease prevention strategy in therapeutic process of accidental damage.[Method]Literature review was applied to summarize and discuss the effect of some approaches guided by disease prevention strategy, including relieving the emotional tension and none-drug treatment.[Result]Three psychological defense lines were constructed during the therapeutic process which were under the guidance of disease prevention strategy, resulting in contribution to improve cognitive evaluation of patients, improve mood and relieve stress disorder. [Conclusion]Disease prevention strategy plays an important role in the psychosomatic recovery of injured students.

Improving the efficiency of occupational disease diagnosis and verification is conducive to protecting the rights and interests of workers, better realizing the legislative value pursuit of the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases, and truly demonstrating the spirit of legal fairness and justice. In 2021, the Administration Measures for the Diagnosis and Verification of Occupational Disease was revised and implemented. The working procedures of occupational disease diagnosis are adjusted and optimized, and the efficiency of diagnosis of occupational disease is greatly improved. They include items such as new provisions specifying working time limits; optimize the working mode; the diagnosis of occupational disease attribution applies to presumptive causality is emphasized and the logical thinking of inversion of burden of proof is carried out. However, the work efficiency of occupational disease diagnosis does not make a great breakthrough in quality, mainly manifests in three aspects: difficult to confirm labor relationships, raising the threshold of occupational disease diagnosis, the administrative field investigation is empty and the diagnosis of occupational disease is complicated. There are many pre-procedures in occupational disease diagnosis, which restrict the efficiency of diagnosis. In the future, attention needs to be paid to promote the independent work of occupational disease diagnosis institutions, and through the revision of the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases. Occupational disease diagnosis institutions should be empowered to confirm labor relationship, so as to lower the threshold of diagnosis of occupational disease and maximize the protection of the rights and interests of workers.
