A large number of studies showed that hairy leukoplakia,pseudomembranous candidiasis,Kaposi' sarcoma,non-Hodgkin's lymphoma,linear gingival erythema,necrotizing ulcerative periodontitis and necrotizing ulcerative gingivitis were the most common lesions in patients with HIV infection and AIDS,and their higher prevalence and incidence rates correlated with the falling CD4 counts and higher virus load of the patients.The use of highly active antiretroviral therapy(HAART) was associated with decreases in the prevalence of oral diseases.Oral manifestations may represent early signs of AIDS di-sease and call attention to disease progression.Oral fluid has been shown to possess superior sensitivity for HIV antibody detection as serum.Abstract:SUMM ARY A large number of stud ies showed that hairy leukoplakia,pseudomembranous cand id iasis,decreases in the prevalence of oral d iseases.Oral manifestations may represent early signs of AIDS d i-sease and call attention to d isease progression.Oral fluid has been shown to possess superior sensitivity forHIV antibody detection as serum.Kaposi’sarcoma,non-Hodgkin’s lymphoma,linear gingival erythema,necrotizing ulcerative periodonti-tis and necrotizing ulcerative gingivitis were the most common lesions in patients with HIV infection and AIDS,and their higher prevalence and incidence rates correlated with the falling CD4 counts and higher virus load of the patients.The use of highly active antiretroviral therapy(HAART) was associated with

Objective To investigate effect of propofol total intravenous anesthesia and sevoflurane inhalation anesthesia on perioperative inflammatory response in patients with lung cancer.Methods Forty patients with simple resection of lung cancer were selected in our hospital.They were divided into observation group and control groups according to random sampling method (n=20).Observation group was given propofol total intravenous anesthesia while control group received sevoflurane inhalation anesthesia.The serum concentrations of MMP-9,TNF-α,IL-6 were compared at the T0 (immediately before the induction of anesthesia) , T1 (1 hour after surgery) , T2 (end of the surgery immediately) , T3 (24 hour after surgery) . Results Compared with the T0 period,the serum concentrations of MMP-9,TNF-αand IL-6 at the T1,T2,T3 periods were increased significantly in the both groups(P<0.05);the concentrations of TNF-α, IL-6 were lower significantly in observation group compared with control group (P<0.05) . Conclusion Propofol anesthesia for resection of lung cancer patients can significantly reduce the inflammatory response.

Objective To investigate the clinical manifestations and inlfuencing factors in the newborns with coagulant function abnormality in the ifrst 24 hours after birth. Methods The coagulation test results and clinical data of 169 newborns in our hospital were studied. Children receiving anticoagulant therapy were assigned as coagulation abnormalities group (n=76) and other healthy newborns were assigned as control group (n=93). The differences of coagulation function between the two groups were analyzed and the inlfuencing factors of coagulation abnormalities were explored. Results The proportions of fetal distress, pneumonia, acidosis and hypothermia of coagulation abnormalities group were signiifcantly higher than that of the control group (χ2=6.18–38.01, P<0.05). Logistic regression analysis showed that fetal distress (OR=12.06, 95%CI:3.71–39.25), pneumonia (OR=4.10, 95%CI: 1.43–11.74) were the high risk factors for coagulant function abnormality, and the differences were statistically signiifcant (both P<0.05). Conclusions Fetal distress, pneumonia were the high risk factors for coagulant function abnormality. Early prevention can help to reduce the incidence of neonatal hemorrhagic disease.

The NYHA class of heart function was improved from Ⅲ-Ⅳ to Ⅰ-Ⅱ. Six-minute hall walk distances were also improved. Conclusion For patients with NYHA class Ⅲ to Ⅳ heart failure and ventricular conduction delay, cardiac resynchronization therapy could reverse left ventricular remodeling and improve heart function.

Objective To study the diagnostic significance of whole blood sample index in the severity of hand, foot and mouth disease, and to analyze its pathogenesis. Methods 194 cases of severe cases of hand, foot and mouth disease were selected as the case group,and 193 cases of mild hand, foot and mouth disease were selected as the control group. Blood samples were collected after admission to study the whole blood samples, including white blood cells, erythrocytes, platelets, medium cell ratio, lymphocyte ratio, mononuclear cell ratio, C-reactive protein test; The patient's immune system, the nervous system were also tested. Results Compared with patients with mild group, the white blood cell level of the patients in the severe group was higher and the albumin level was higher, the difference was statistically significant (P<0.05), the monocyte ratio, the T cell ratio was lower, the difference was statistically significant (P<0.05). Conclusion The white blood cell level and monocyte ratio of patients with severe hand, foot and mouth disease have changed. The whole blood sample has a certain sensitivity to the diagnosis of severe hand, foot and mouth disease.

Objective To study the characteristics of toe-to-thumb transplantation in a group of infants who completely lacked the thumb.The mean age was 24.6 months,and the youngest was 10 months old,The operative technique and rehabilitation were studied.Methods In two infants with Ⅲ-Ⅳ? defects of the thumb together with multiple injuries of fingers,the wounds were debrided and toe-to-thumb transplantation was done later.In case 3 Ⅲ? defect of the thumb together with palm injury,one-stage toe-to-thumb transplantation and the palm injury was covered with an abdominal flap were done at the same time.Considering the characteristic physiological structure of a dorsalis pedis and the first metatarsal arteries.In the infant,minimally invasive operation under 10? microscope was employed.A series of early functional exercises was given for the reconstructed thumbs.Results The reconstructed thumbs completely survived,hand function was recovered 3-6 months after the operation.With follow-up for longer than 2 years in 2 cases,it was noted that the reconstructed thumb grew consistent with the wounded hand.The appearance and function thumb were satisfactory.Conclusion Toe to thumb transference was successful in infancy,with the combined technique of minimally invasive and plastic surgery.Reconstruction of the thumbs can be completed in two stages on immediately after injury.The appearance and function can be restored.[

Objective To establish an effective technique in reservation and function reconstruction of a leg, in which all the muscles except gastrocnemius necrosed induced by the delayed necrosis of all the intermuscular vessels, the foot was linked only by skin, fascia and tibia. Methods The leg was linked with foot only by the skin, fascia, caput mediale of gastrocnemius and tibia when all the muscles, intermuscular vessels and fibula were removed. The direct island flap of tibialis posterior artery was cut from the healthy limb and used to cover the 4/5 length and 1/3 circumference of bone-fascia raw surface, then to anastomose the both arteries of the flap and the caput lateral gastrocnemius when dividing the pedicles. As soon as the raw surface healed, fuse the ankle in the functional situation and fix the flexor and extensor tendon in the proper situation. Results With sufficient blood supply from the skin and fascia of the flap, the raw surface healed soon, the severe ischemia pain relieved, and the circulation and sensation recovered gradually. The crutching and walking function of the leg reconstructed at last. Conclusion When all the necrotic intermuscular vessels and muscles except caput mediale of gastrocnemius were removed, the necrosis may be delayed by means of reticular collateral circulation among skin, deep and superficial fascia and tibia of the injured limb. However, the blood supply is very little, the severe ischemia wound and ischemia pain can't be healed. Through the tibialis posterior artery direct island skin flap of the healthy leg to cover the dystrophic wounds, the blood supply of the leg can be improved. As a result, the leg survives and its function is reconstructed, and an eternal axial-pattern artery for the wound leg through arteries anastomosis is rebuilt.

Since the first reported case of swine influenza A in Mexico,a total of 15 510 cases have been confirmed in 53 countries by May 29,2009.On April 29,2009,the World Health Organization(WHO)raised its pandemic alert from grade 4 to grade 5.The virus is described as a new subtype of A/H1N1 and is not detected in pigs or humans previously.The virus is sensitive to oseltamivir and zanamivir,but resistant to amantadine and rimantadine.The genetics of the virus are so novel that humans are unlikely to have much immunity to it.The virus can transmit from human to human;therefore it is necessary to enforce quarantine measure for close contactors because the virus transmits during latency.Precaution methods like covering noses and mouths with a tissue when coughing or sneezing can reduce the transmission opportunity.Hands should be washed frequently with soap,especially after coughing or sneezing.Public places with ventilation conditions,personal health behavior and health condition are critical for the prevention and control of this epidemic.

Objective To probe the pathogenesis of long bone defects and damage to epiphysis as the result of postoperative infections following fractures in the childhood of patients, and to look for ideal ways to prevent and repair the defects and damages. Methods The treatment of the infected bone defect of a tibia had been continued for one year following fracture in one four-year old patient, and the treatment of the infected bone defect of a humerus had been continued for ten years following fracture in another seven-year old patient, but all the treatments had failed. The injured limbs developed bone infection, bone defect, bone exposure, shortening, and pseudoarthrosis deformities at last. Then the lesions were completely cleaned, and the deformities of the infected bones were corrected in one stage, with reconstruction of the bone and the repair of the wounds by transplantations of fibular free flaps. Results Both fibular free flaps survived in one stage transplantation. The bones of the injured limbs healed half a year after the operations, and weight-bearing and walking functions of the injured limbs recovered as well. Conclusion Transplantation of fibular free flap was an ideal way to treat a long bone defect as a result of postoperative infection following fracture in the childhood. The early appropriate treatment of postoperative infection following fracture is very important to avoid bone and epiphysis damages.
