OBJECTIVESTo investigate the changes of liver function during the course of serious acute respiratory syndrome (SARS) and to explore its possible influence factors.

METHODSThere were 91 patients with common SARS, and 23 patients with severe SARS, and 61 common pneumonia patients served as the controls. The liver functions of all the patients were measured.

RESULTSThe rate of anomaly liver function in the common SARS patients group was 68.1%, which was higher than that in the common pneumonia patients group (24.6%), chi2=27.7, P<0.01. The changes mainly existed in the mild to moderate elevation of alanine aminotransferase and aspartate aminotransferase. The severe SARS patients were older and the changing rate of liver function was as high as 95.7%.

CONCLUSIONSThe damage possibility of liver function in SARS patients is higher than that in common pneumonia patients. The damage is light and related to SARS itself. The damage of liver function in the severe SARS patients may have close relationship with age.

OBJECTIVETo investigate appropriate ways for screw placement of pedicle of vertebral arch in the horizontal plane.

METHODSFifteen preserved thoracolumbar spine specimens (T(11)-L(5)) were used and divided into three groups at random. Firstly four anatomic parameters indicating screw positions in the horizontal plane were measured. Secondly the methods of Roy-camille, Magerl, and authors' segmental differences were used to place successively the screws of the pedicles with 5 mm, 6 mm, and 7 mm in diameter. Coincidences between the drilling point, drilling direction and pedicle axis, and ruptures of the pedicle as well as the length of the screw in the vertebral body were observed.

RESULTSFour anatomic parameters at various segments showed significant differences (P<0.05). The drilling point by the Roy-camille's method deviated medial to pedicle axis in most segments, and its drilling direction did not coincide well with most E-angles of the pedicles. The drilling point by Magerl's method coincided relatively well with pedicle axis in lumbar vertebrae, but there were still some differences between its drilling direction and E-angles of the pedicles. The method of segmental differences coincided the best with the pedicle axis. The lengths of screw in the vertebra were relatively long by both Magerl and segmental difference methods. When 5 mm diametral screw was used by the three methods, the rupture rate was very low. When 6 mm and 7 mm diametral screws were placed, the rupture rate was accordingly increased. Of the three methods, Roy-camille's method showed a relatively high rupture rate, while the method of segmental differences a comparatively low rupture rate. Various degrees of rupture of the pedicle of vertebral arch were found at the juncture of the thoracic and lumbar vertebrae when 6 mm or 7 mm diametral screws was used by any screw placement method. In contrast, the rupture was seldom seen at the lower lumbar vertebrae when 7 mm diametral screws were used.

CONCLUSIONSThe segmental difference method is proved to have the anatomic safety and screw biomechanical stability. It is appropriate to choose different diametral screws, different drilling points and directions according to different segments of the vertebra.

Objective To understand the related factors of rabies epidemic and provide the basic data for rabies control and prevention in China by statistic and retrospective analysis of rabies surveillance data in 2010.Methods We used descriptive epidemiology method and statistic analysis to analyze the epidemiological characteristics of rabies in 2010 of China.Results 2048 rabies cases were rabies cases were reported in 817 counties (districts) in 2010,which dropped 7.46％ compares to 2009.The incidences in children and elder people were high; farmers are main occupation of the cases,the male to female ratio of the cases was 2.44:1.Children and older people are higher acquired rabies than other age population.640 cases reported through national rabies sentinel surveillance system,87.50％ cases were caused by exposed to dogs,bite was the main exposure reason.The situation of deposing wounds was poor,and the use of vaccine was still low in individual cases,but in the rabies clinic cases under surveillance,the vaccine usage can reach 98％,the usage of immunoglobulin (RIG) or anti-serum for category Ⅲ exposure in either group cases was not high.Conclusion The epidemic of the rabies in 2010 was eased,Out-patient post-exposure prophylaxis was in good station,but there are still lots of problem existed: post-exposure prophylaxis of individual case was not desirable yet.

To study the effects of glycosylation on survival of cold-storage human platelets by using rabbit model. (51)Cr-labeling platelets were used to detect the platelet storage survival. The human platelets (2.0 x 10(12)/L) treated with 5 g/L uridine diphosphate galactose (UDP-Gal) were stored in 4 degrees C refrigeratory up to 10 days. The survival of human platelets in rabbits whose reticuloendothelial system was inhibited by the administration of ethyl palmitate was monitored in blood drawn at various times after the platelet transfusion. The results showed that the survival rate of platelets was significantly increased in cold-storage human platelets by UDP-Gal treatment. The survival rates of platelets at 2 hours after transfusion into rabbits in groups of fresh platelets group, UDP-Gal + cold platelets group and cold platelets group were (68.9 +/- 8.5)%, (65.4 +/- 8.0)% and (5.0 +/- 2.6)%, respectively. Compared with cold platelets group, significant differences were seen among all groups (P < 0.01). UDP-Gal + cold platelets group had no significant differences compared with fresh platelets group (P > 0.05). It is concluded that UDG-Gal can provide the protective effect on cold-storage human platelets and prolong the survival time of refrigerated human platelets in rabbit model.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.
