OBJECTIVETo investigate variations and significance of plasma fibrinogen in patients with severe acute respiratory syndrome (SARS).

METHODSTotally 148 patients with SARS were divided into the following groups: initial stage group (44 cases) and after the initial stage group (104 cases), common type group (87 cases) and severe type group (61 cases), unilobar lung involvement group (49 cases), bilobar lung involvement group (53 cases) and diffuse lung involvement group (46 cases). The values of plasma fibrinogen of the 148 SARS patients were analyzed and compared among the different groups.

RESULTSThe mean value of plasma fibrinogen (x +/- SD, 522.29 +/- 154.87 mg/dl) of the 148 cases was higher than the normal value (p less than 0.01). There were significant differences between the initial stage and after initial stage groups, between the common and severe type groups, and among the unilobar, bilobar and diffuse lung involvement groups (p less than 0.05).

CONCLUSIONtheses results suggested that elevation of peripheral blood fibrinogen in SARS patients may play an important role in development and progress of the disease and its treatment.

OBJECTIVETo explore the operative method for the treatment of syndesmosis injury in ankle fractures.

METHODSA retrospective study was done on 21 ankles of 20 patients included male 11 and female 9;the range of age were from 27 to 52 years with an average of 36 years) with syndesmosis injury in closed ankle fractures from September 2005 to December 2007. All patients with ankle fractures and syndesmosis injury were diagnosed by the history, physical examination and radiology, then treated with open reduction, internal fixation, and syndesmotic stabilization with a three-cortices syndesmotic screw according to the Lauge-Hansen classification system. Radiological evaluation comprised tibiofibular overlap, total clear space and medial clear space. The clinical effects were evaluated according to modified Baird-Jackson standard.

RESULTSAll patients were followed up from 1.0 to 2.2 years with an average of 1.3 years. Radiographic measurements were detailed as follows: tibiofibular overlap averaged (0.46 +/- 3.56) mm in preoperative and (7.14 +/- 0.62) mm in postoperative; mean total clear space (5.69 +/-0.88) mm in preoperative and (3.28 +/- 0.39) mm in postoperative; medial clear space averaged (5.67 +/- 1.23) mm in preoperative and (3.12 +/- 0.33) mm in postoperative; tibiofibular overlap in mortise view averaged (-0.87 +/- 0.96) mm in preoperative and (2.91 +/- 0.30) mm in postoperative. There was significant difference above data between preoperative and postoperative (P < 0.01). Four cases were confirmed minor tibiofibular diastasis through CT scans during postoperative. The modified Baird-Jackson scoring was from 62 to 98 scores with an average of (86.24 +/- 13.26) score at the final review. Of them, 13 ankles had not pain; 16 ankles reported no instability complaints; 11 ankles gained normal walking ability; 8 ankles could run normally; 11 ankles could return work without any restrictions. Activity of ankle in dorsiflexion, plantar flexion, inversion and eversion were respectively (21.05 +/- 5.00) degrees, (33.57 +/- 5.76) degrees, (19.48 +/- 4.57) degrees and (24.05 +/- 4.86) degrees. Three cases had radiological and clinical manifestations of osteoarthritis, but no breakage of syndesmotic screw in all cases. There were excellent results in 12 cases, good in 2, fair in 4, poor in 3.

CONCLUSIONThe treatment for the syndesmosis diastasis with a three-cortices screw fixation in ankle fractures is effective. Good functional outcome can be obtained with anatomical restoration of the tibiofibular syndesmosis. The repair of deltoid ligament is important for stability of the lower tibiofibular syndesmosis. Removal of the screw before weight loading should be performed to avoid possible screw breakage.

OBJECTIVETo explore the clinical results of arthroscopy-assisted open reduction and internal fixation for the treatment of acute Lauge-Hansen stage IV ankle fractures.

METHODSA prospective cohort of study was done in 42 patients of acute ankle fractures treated with arthroscopy-assisted open reduction and internal fixation from January 2008 to December 2009. According to Lauge-Hansen classification, there were 26 supination-eversion stage IV fractures, including 11 females and 15 males; with an average age of (36.8 +/- 11.7) years; and there were 16 pronation-eversion stage IV fractures, including 6 females and 10 males, with an average age of (37.6 +/- 11.2) years. All the patients were treated with arthroscopy-assisted open reduction and internal fixation,and intra-articular disorders were observed. Syndesmotic diastasis was treated with three-cortices syndesmotic screw, and osteochondral injuries were disposed by Cheng-Ferkel staging system. The clinical effects were evaluated according to AOFAS scores.

RESULTSAll the patients were followed up for 1 year. At the final review,the mean AOFAS score was (92.00 +/- 9.32). Twenty-eight patients got an excellent result, 11 good, 3 fair. Lesions of the cartilage were found in 31 cases. The AOFAS scores of patients with osteochondral lesions were higher than those of patients without osteochondral lesions. The AOFAS scores of patients with osteochondral lesions below C grade were higher than those of patients with osteochondral lesions above C grade. The AOFAS scores of patients with osteochondral lesions were higher than those of patients with osteochondral lesions above C grade. The AOFAS scores of patients with syndesmosis fixation were lower than those of patients without syndesmosis fixation.

CONCLUSIONIntra-articular disorders are common in Lauge-Hansen stage IV ankle fractures, and osteochondral lesion and sydesmosis diastasis are the most important prognostic factor that leads to unsatisfactory ankle functions. Arthroscopy-assisted open reduction and internal fixation for the treatment of acute ankle fractures is not only helpful to anatomical reduction of the articular surface, but also can improve the clinical results with effective diagnosis and treatment of combined intra-articular disorders.

OBJECTIVESTo determine whether -238G/A and -857C/T polymorphisms of tumor necrosis factor-alpha (TNF-alpha) gene promoter were associated with outcomes of hepatitis B virus infection.

METHODSA total of 246 HBV self-limited infected subjects and 443 chronic hepatitis B (HB) patients were recruited in this case-control study. TNF-alpha-238G/A and -857C/T gene promoter polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSThe frequency of TNF-alpha-238 GG (90.7%) in chronic HB group was significantly lower than that (95.1%) in self-limited group (P = 0.041). The frequency of TNF-alpha-857 CC (79.7%) in chronic HB patients was significantly higher than that (70.9%) in self-limited infected subjects (P = 0.021). Multiple logistic regression analysis revealed that both TNF-alpha-238GA and -857CC were independently associated with chronic HB.

CONCLUSIONSTNF-alpha promoter variants are likely to play a substantial role in influencing the outcomes of HBV infection.

OBJECTIVETo explore whether the vitamin D receptor gene (VDR) polymorphisms are associated with the outcomes of hepatitis B virus (HBV) infection in Chinese Han population.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphisms of Fok I locus in exon 2 and Taq I locus in exon 9 of VDR gene. One hundred and eighty-four chronic hepatitis B patients and 205 asymptomatic HBV carriers were recruited to make the comparison of frequencies of genotype and haplotype of the VDR gene between the patients and the carriers.

RESULTSThe univariate analysis showed a significant difference in Fok I polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group. The FF genotype frequency in chronic hepatitis B patients group was 44.6%,higher than 31.7% in asymptomatic HBV carriers group (P<0.05). After adjusting the confounders by multiple logistic regression analysis, the result still showed a significant difference in Fok I site polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group (OR=1.95, P<0.05). The FT haplotype frequency in chronic hepatitis B patients group was higher than that in asymptomatic HBV carriers group (OR=1.45, P<0.05). The fT haplotype frequency in chronic hepatitis B patients group was lower than that in asymptomatic HBV carriers group (OR=0.72, P<0.05).

CONCLUSIONVDR gene polymorphism may be an influence factor of genetic susceptibility to HBV infection.

To establish a method for simultaneous determination of the contents of sesamoside, menthyl chloride, chlorogenic acid, caffeic acid, 8-O-acetyl-phloridzin methyl ester, forsythiaside B, luteolin, and ergosterol, the LIPLC analysis was performed on a Kinetex XB-C₁₈ (4.6 mm×50 mm,2.6 μm)column with acetonitrile (A)-0.1% phosphoric acid solution (B) as the mobile phase. The flow rate is 1.0 mL min⁻¹. The detection wavelength was 238, 320 and 350 nm and column temperature was 30 ℃. The results showed that the eight components could be completely separated with good linear relationships (r≥0.999 8) in the linear range. The average recoveries were 96.61%-100.4%. The method was simple with strong specificity and high precision. It can be used for the identification and quality evaluation of the Lamiophlomis rotate.The results also showed that there was a correlation between the various components, and the habitat was the main factor affecting the content of the eight components. However, the degradation gradient had no obvious effect on the contents, while the content of sesamoside was significantly decreased after one year of storage.

OBJECTIVETo accurately calculate the protein requirements in Chinese young adults using the indicator amino acid oxidation technique.

METHODSNine women and ten men received a restricted daily level of protein intake (0.75, 0.82, 0.89, 0.97, and 1.05 g/kg), along with L-[1-13C]-leucine. Subjects' protein requirement was determined by a biphasic linear regression crossover analysis of F13CO2 data. In doing so, a breakpoint at the minimal rate of appearance of 13CO2 expiration specific to each level of dietary protein was identified. This trial was registered with the Chinese clinical trial registry as ChiCTR-ONC-11001407.

RESULTSThe Estimated Average Requirement (EAR) and the Recommended Nutrient Intake (RNI) of protein for healthy Chinese young adults were determined to be 0.87 and 0.98 g/(kg•d), respectively, based on the indicator amino acid oxidation technique.

CONCLUSIONThe EAR and RNI of mixed protein are 5% and 16% that are lower than the current proposed EAR and RNI (0.92 and 1.16 g/(kg•d), respectively), as determined by the nitrogen balance method. The respective EAR and RNI recommendations of 0.87 and 0.98 g/(kg•d) of mixed protein are estimated to be reasonable and suitable for Chinese young adults.
