Under the serious inadequate circumstances of government’s input on public hospitals, how public hospitals can ensure the public welfare and guarantee a reasonable return is the task for managers. Based on the total cost accounting of the hospitals , the patient costs are solved into the cost structure with the same structure of accounting , combined with average profit rates of accounting units, to calculate single patient profit, to summarize diseases and calculate disease profit rate and related indexes on this basis, to provide references for hospital management from new prospective.

Objective: To explore the major factors which influence the hospitalization expense of fibroid operation,provide references for the effective control of the increasing medical expense and ease the burden of patients. Methods: From January 2011 to December 2012, 1 837 cases of fibroids in our hospital were investigated, and pathway analysis method was used to analyze the factors which influence the hospitalization expense. Results: Operation method, whether use hysterectomy, the year of medical treatment, complication, medical group and nosocomial infection are the critical influencing factors which can directly effect on the hospitalization expense, and these factors not only have direct effects but also have indirect effects on hospitalization expense. Conclusion:Government and medical institutions should take comprehensive measures to decraease hospitalization expense, including the reasonable treatment options, rational drug use, active treatment and prevention of infection.

Objective: Our aim was to investigate the alteration of p16 gene in human pancreatic carcinoma. Methods: A total of 66 human pancreatic tissue specimens, comprising 51 with pancreatic carcinomas and 15 normal pancreatic tissue specimens, were examined for homozygous deletion and mutation of p16 gene by using PCR-SSCP method. Results: No mutation and deletion was detected in 15 normal pancreatic tissue samples. Of 51 pancreatic carcinoma specimens, only one was found mutation for p16 gene in PCR-SSCP assay, and the deletion of the p16 gene in 23 samples were confirmed by using PCR, with a 45% p16 gene deletion rate. Conclusion: These data suggest that p16 gene alterations may play a role in the progression of human pancreatic carcinoma.

Objective:To clarify the differences of host immune responses at different stages of HBV infection. Methods:We constructed three HLA-A*0201/HBV tetramers with immunodominant epitopes of core18-27,polymerase 575-583 and envelope 335-343,and analyzed antigen specific CD8+ T cells and the expression of CD127 in peripheral blood mononuclear cells ( PBMCs) from patients infected with HBV using these HLA-A*0201/HBV tetramers. Results: The frequencies and expansion ability of antigen specific CD8+ T cells in most self-limited HBV infected individuals were higher than that in chronically HBV infected patients. In low copy period the frequencies of antigen specific CD8+ T cells were similar to those in immune clearance phase at a high viral load and liver damage and in immune clearance phase, which had no significant correlation with virus quantitation and ALT level. In chronic infection the ability of antigen specific CD8+ T cells proliferation was inversely proportional to the viral titer. In most self-limited HBV infected individuals the IFN-γsecretion functions of antigen specific CD8+ T cells were higher than in chronic infection,but in immune tolerance phase these cells lost the ability. HBsAg level was different at different stages after HBV infection:it was highest in immune tolerance phase,but in immune clearance phase,activity period and low copy period the correlation with HBV DNA replication gradually declined. The frequency of CD8+ CD127+ T cells in chronic HBV infection was lower than the control group and self-limited infection group,especially in immune tolerance with HBeAg+ and immune clearance phase. Conclusion: The frequencies of antigen specific CD8+ T cells are not the main determinant of immune-mediated protection in chronic HBV infection,memory antigen specific CD8+ T cells are not clear or missing,which provides the possibility for therapeutic vaccines and immunization therapy.

Objective To study incidence of deep vein thrombosis (DVT) in the acute phase and follow-up period after stroke, and to investigate risk factors of DVT. Methods This was a prospective study at multi-centers. Ultrasonography was used for detecting DVT on both lower extremities in all patients at 10-14 days after the onset of stroke. All patients were followed up for 6 months after discharge. The incidence of DVT was examined in the acute phase and in the follow-up period of stroke. A variety of patient and treatment related factors were compared between stroke patients with DVT and without DVT to identify DVT risk factors. Results The incidence of DVT in the acute period of stroke was 4. 49%. Among DVT patients, 51.6% patients presented clinical DVT symptoms. By multiple factors logistic regression analysis,age ( ≥70 years, OR = 1.63, 95% CI 1.08-2. 84), bedridden( OR =4. 85, 95% CI 2.65-9. 68 ), wells score ≥ 2 ( OR = 3.96, 95% CI 1.86-7. 86 ), lower limbs NIHSS score ≥ 3 ( OR = 4. 56, 95% CI 2. 07-8. 85 ), high D-dimer ( OR = 3.45, 95% CI 2. 01-8. 52 ), low BI scores ( OR = 2. 98, 95% CI 1.52-6. 47 ), rehabilitation therapy ( OR = 1.82, 95% CI 1.22-3.43 ) and anticoagulant therapy ( OR =1.91,95% CI 1. 34-4. 92 ) were independent risk factors of DVT in the acute phase of stroke. Among them, the rehabilitation therapy and anticoagulant therapy were protective factors. The incidence of DVT in the follow-up periods was 1. 51%. Age ( ≥ 70 years, OR = 1.82, 95% CI 1.21-3.98 ), bedridden after discharge( OR = 5. 12, 95% CI 2. 82-11.32), lower limbs NIHSS score ≥3 ( OR = 4. 25, 95% CI 2. 11-7. 87), low BI score( OR = 2. 18, 95% CI 1.18-6.23 )at the time of discharge and DVT in acute period (OR =3.81,95%CI 1.87-7.48)were independent risk factors of DVT in the follow-up period of stroke.Conclusions Stroke patients, particularly old-aged stroke patients, are a high-risk group of developing DVT. 48.4% DVT patients had no clinical DVT symptoms but were diagnosed only by ultrasonography.There are multiple independent risk factors of DVT after stroke. It is necessary to monitor and prevent DVT in the stroke patients with the risk factors. The rehabilitation therapy and anticoagulant therapy may decrease incidence of DVT.

OBJECTIVETo investigate the effect of epidermal stem cells from human hypertrophic scar (HS-ESCs) on the skin wound healing in nude mice.

METHODS40 mice were randomly divided into two groups as experimental group (n = 20) and control group (n = 20). Wounds, 1 cm in diameters, were made on every mouse back. The wounds were treated with HS-ESCs and erythromycin ointment in experimental group, or only with erythromycin ointment in control group. The wound healing was observed during the following 14 days. The expression of collagen-I, collagen-III, epidermal growth factor (EGF), fibroblast growth factor (FGF2) , transforming growth factor (TGFbeta1, and TGFbeta2) were studied.

RESULTSThe wound healing time in the experimental group was (20.8 +/- 0.84) d, which was (25.6 +/- 0.89) d in the control group. HE staining revealed that the extent of vascularization in the experimental group was 11.60 +/- 0.55, while it was 8.04 +/- 0.33 in the control group. Immunochemistry analysis showed the expression of collagen-I, collagen-III, EGF, FGF2, TGFbeta1, and TGFbeta2 in the experimental group were significantly higher, compared with those in control group (P < 0.05).

CONCLUSIONHS-ESCs may promote wound healing through enhancement of the vascularization of the wound tissue and the expression of growth factors.

Objective To evaluate the diagnostic value of US, ECT, CT and MRI in primary hyperparathyroidism (PHPT). Methods Data of 34 PHPT patients with diagnosis confirmed by postoperative pathology were retrospectively reviewed from January 1, 1990, through March 31, 2004. Results The preoperative diagnosis in 22 out of 25 cases (88%) undergoing preoperative ultrasonography of the neck with a positive result was verified by intraoperative findings. For 99m Tc-MIBI, CT and MRI, the positive results were 95%, 69% and 100% respectively. Conclusion Ultrasonography and 99m Tc-MIBI should be considered as the first choice for preoperative loci localization in patients with PHPT. Ultrasonography and 99m Tc-MIBI in combination is more sensitive and accurate for the localization of PHPT.

5 years, 1 for 3 years, 4 for less than 1 year. In addition, metastatic tumors to the spleen were found in 5 patients, splenectomy with or without combined resection of other organs was performed in all 5 patients. Conclusions Imaging examination is the main method of diagnosis for splenic tumors. Partial splenectomy is recommended for benign tumors. For malignant splenic tumors, surgery, as the main aspect of combined therapy, is required.

OBJECTIVEOn the basis of the concept of adhesive deformity from upper eyelid fold formation, the clinical results after using various methods to correct the adhesive deformities are summarized.

METHODSA total of 33 cases of adhesive deformity from upper eyelid fold formation have been treated using various corrective methods including taking off the sutures, shifting of the septal fat or the pre-septal orbicularis muscle, transferring of pretarsal orbicularis muscle, grafting of autogenous fat tissue, and repairing or/and shortening of the palpebral levator. Postoperative follow-up ranged from 3 months to 2 years.

RESULTSThe effective results have been got with the used methods except shifting of the pre-septal orbicularis muscle or transferring of pretarsal orbicularis muscle.

CONCLUSIONSThe suitable methods to correct the adhesive deformity from upper eyelid fold formation must be chosen according to the causes and the local situations.
