Diagnosis related groups (DRGs)have been widely used in many countries and regions.The versions of DRGs in different regions are modified according to the local circumstances and conditions.Beijing version DRGs (BJ-DRGs)is the first DRGs system in Chinese,which was developed locally based on the conditions of medical information system and health relative policies in Beijing.This paper introduced the grouping principles,logic and methodology of BJ-DRGs.Taking“ear,nose,mouth and throat disorders”for example,this paper demonstrated the grouping process of BJ-DRGs.

Objective Beijing plans to run a DRGs-PPS pilot.The relative height of each DRG group produced by the price of charge categories.Because of serious distortions of medical services prices,DRGs'weight must be adjusted.Methods Dividing medical service into 5 major class-medical,nursing,technique,drugs and consumables,management,a conversion with currency were established to produce the cost.Results The weight of groups involve intervention from MDCF are drop.ConclusionThe weight regulated can optimize resources allocation and reflect the ture value of medical service.

Objective To compare the effect of allograft and autograft of bone-patellar tendon- bone (B-PT-B) under arthroscopy in reconstruction of anterior cruciate ligament (ACL).Methods The injured ACL was reconstructed under arthroscopy by using autograft of B-PT-B in 30 cases and al- lograft of B-PT-B in 28 cases from January 2000 to August 2003.After over twelve months follow up,a comparison was done on rehabilitation of quadriceps femoris,knee stability,the Lysholm's score of knee and the enlargement of tunnel in both groups.Results Both groups obtained marked improvement of knee stability and symptoms after operation.But in the early time,the rehabilitation of quadriceps femoris in the ailograft group is faster than that in the autograft group.The rehabilitation of quadriceps femoris, knee stability and the Lysholm's score of knee were similar at 12th month (P＞0.05).There could be seen enlargement of tunnel in both groups,with more in the allograft group (P＞0.05).Conclusion For arthroscopic reconstruction of anterior crucial ligament (ACL),allograft of B-PT-B is good substitute, for it is characterized by effectiveness,convenience and minor side effect.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.

Objective To investigate the mechanism of pulmonary fibrosis induced by paraquat (PQ),and the effect of Xuebijing injection in treatment of PQ poisoning.Methods Seventy-two male Wistar rats were randomly divided into control group,PQ poisoning group,and Xuebijing intervention group,with 24 rats in each group.Pulmonary fibrosis was induced by single garage at the dosage of 50 mg/kg of PQ,while 1 mL of distilled water was given by gavage in control group.Xuebijing injection at the dosage of 4 mL/kg were given intraperitoneally at 30 minutes after exposure to PQ in Xuebijing group,and it was repeated every 12 hours; same amount of physiological saline was given intraperitoneally in PQ group and control group.The experiment lasted for 14 days.Six rats in each group were sacrificed on 1,3,7,14 days,respectively,after insult,and 30 minutes after the last intervention.The lung tissues were harvested,the changes in pathology in lung tissue and the degree of pulmonary fibrosis were observed with optical microscope with hematoxylin-eosin (HE) staining and Masson stain.The ultrastructure changes in lung tissues were observed with transmission electron microscopic,and the content of hydroxyproline (HYP) in the lung tissue was determined by alkaline hydrolysis.The expression of mitochondrial fusion protein 2 (Mfn2) was determined by Western Blot.Results ① HE staining:in PQ group,inflammation was most marked on the 3rd day.On the 7th day,exudates in the alveoli started to be organized,and hypertrophic fibroblasts were seen to secrete slim collagen fibers,and fibrosis could be seen in alveoli.On the 14th day,intensive hyperplasia of fibroblasts could be observed,and the alveolar structure was destroyed and collapsed,with deposition of collagen deposited with formation of pulmonary fibrosis.At the same time,pathologic changes were milder in Xuebijing group than those in PQ group.② Masson staining:the degree of inflammation in alveoli and pulmonary fibrosis were less marked in Xuebijing group than those of PQ group on the 14th day.③ Under the transmission electron microscopy,it was found that the mitochondria of lung tissue cells was relatively less in number on the 14th day in PQ group,and the majority of them underwent degeneration,swelling and damage.Basement membrane became folded,alvcoli were collapsed,and fibrosis was obvious.These changes were less serious in Xuebijing group.④ Content of HYP (μg/g):contents of HYP in lung tissues on the 3rd day in PQ group and Xuebijing group were significantly higher than those in control group (743.3 ± 50.2,718.1 ± 34.0 vs.665.8± 6.6,both P＜0.05),it then increased gradually,but the contents of HYP in Xuebijing group were significantly lower on the 7th day and 14th day than those in PQ group (790.5 ± 23.8 vs.876.7 ± 42.0,812.9 ± 72.3 vs.931.3 ± 33.0,both P＜0.05).⑤ Expression of Mfn2:the expression of Mfn2 in control group was relatively lower.The expression of Mfn2 in PQ group was increased gradually under stress,but its rate was low.The expression of Mfn2 (A value) in Xuebijing group was significantly higher than that in PQ group on the 1st day (0.731 ±0.035 vs.0.618 ±0.029,P＜0.05),and it was elevated steadily,reaching the peak on the 7th day (0.732 ± 0.037 vs.0.669 ± 0.034,P＜0.05),but it was lower than that of PQ group on the 14th day (0.708 ± 0.034 vs.0.765 ± 0.041,P＜0.05).Conclusions Xuebijing reduces lung inflammatory reaction and pulmonary fibrosis as a result of PQ poisoning.The mechanism is that Xnebijing regulates and increases expression of Mfn2 in lung tissue.

Objective To study the effect of Zusanli and Guanyuan electroacupuncture ( EA) on inflammatory reaction in patients with sepsis. Methods A prospective and randomized trial was carried out in 58 sepsis patients, and the patients were randomly divided into EA group and control group. Patients in both groups were given conventional western medicine treatment, and EA group received EA at acupoints of Zusanli and Guanyuan additionally. The hospitalization time in intensive care unit ( ICU) of the two groups was compared. The changes of serum lactic acid (LA) level and inflammatory indexes including white blood cell and neutrophil count, C- reactive protein (CRP), erythrocyte sedimentation rate (ESR) and procalcitonin (PCT) of the two groups were observed before and after treatment. Results The hospitalization time in ICU of EA group was less than that of the control group, and the difference was statistically significant ( P<0.05) . On the seventh day after treatment, the serum LA level of EA group was significantly lower than that of the control group ( P<0.05) . Inflammatory indexes of EA group were decreased after treatment compared with those before treatment ( P<0.05) , and on seventh day after treatment, the inflammatory indexes of EA group were significantly lower than those of the control group ( P<0.05) . Conclusion EA at acupoints of Zusanli and Guanyuan is effective for the treatment of sepsis through reducing the inflammatory reaction of sepsis patients.
