OBJECTIVEThere is little knowledge on whether there is clustering of inflammatory biomarkers, such as C-reactive protein (CRP), soluble intracellular adhesion molecule1-1 (sICAM-1), and angiotensin II (Ang II), in individuals with hypertension in the Mongolian population. In the present study, we investigated this relationship in a Mongolian population in China.
METHODSA total of 2589 adult Mongolians, aged 20 years and older, were recruited as study participants. Data on demographics, lifestyle, family history of hypertension, blood pressure, and blood chemistry were collected, and inflammatory biomarkers were measured in all participants.
RESULTSThe proportion of subjects with increased levels of two or three biomarkers was significantly higher in those with hypertension (21.0% and 6.0%, respectively) than in those with prehypertension (12.7% and 0.5%, respectively) or normotension (8.1% and 0.2%, respectively). The multivariate adjusted odds ratios (95% confidence interval) of hypertension associated with increased levels of one, two or three biomarkers were 0.94 (0.72-1.22), 1.42 (0.93-2.16), and 11.08 (1.45-84.80), respectively, compared with subjects with no increase in any biomarker.
CONCLUSIONHypertension was associated with a cluster of inflammatory biomarkers in the Mongolian population.

PURPOSE: The purpose of this study was to construct a fetal animal model of congenital diaphragmatic hernia in a lamb under domestic environments. METHODS: Left-sided diaphragmatic hernias were created in seven fetal lambs at about 85 days' gestation (experimental group). Three other fetal lambs did not receive any surgical procedure and served as control group. Four of these lambs (3 in the experimental group and 1 in the control group) were delivered after a sufficient intrauterine period. The morphological changes of lung development were compared between the two groups. RESULTS: Creation of diaphragmatic hernia resulted in marked hypoplasia in fetal lung development. In this experiment, the maternal mortality was 33.3%, and the fetal mortality was 60% which are relatively high as compared with previous reports. CONCLUSION: From this data, the authors concluded that experimental fetal diaphragmatic hernia can be established although the technique for the measurement of gestational age, anesthesia and postoperative care should be improved to overcome domestic inexperience in using the lamb as an experimental animal.

Spontaneous renal subcapsular hematoma is a rare, life-threatening condition that is usually caused by benign and malignant renal tumors, vascular diseases, inflammatory disorders, blood dyscrasias, and seldom suspected clinically. The characteristic clinical features are abdominal pain, a mass in the flank and signs of internal bleeding. Severe preeclampsia is also a major contributing factor of the renal hematoma. Because renal function is decreased in spontaneous renal subcapsular hematoma, physicians should be aware of the clinical symptoms and signs, appropriate investigation and management may be life-saving. This case of spontaneous renal subcapsular hematoma and acute renal failure complicated by severe preeclampsia, which occurred after delivery and was treated conservatively.

Complete mannanase gene with two introns was cloned from Trichoderrna reesei by PCR. The two introns were then removed by overlap extension PCR. The gene encoding the mature mannanase protein was inserted into the expression vector pPIC9K, downstream of a alpha-factor signal peptide sequence. The resultant recombinant vector was named pM242. After linearized with Sac I , pM242 was transformed to Pichia pastoris GS115 by electroporation. After screening, the recombinant strain Gpmf25 that expresses the secretory protein at high level was obtained. The activity of the recombinant mannanase reached 12.5 IU/mL. Optimum pH and temperature for the recombinant enzyme were 5.0 and 80 degrees C, respectively. The enzyme was stable at pH 5.0-6.0 and maintained over 50% of original activity after incubation at 70 degrees C for 30 min.

OBJECTIVETo improve the diagnostic accuracy of primary salivary gland-type lung cancer on CT.
METHODSThe CT findings of 13 pathologically proven primary salivary gland-type lung cancers (mucoepidermoid carcinoma, n = 8, adenoid cystic carcinoma, n = 5) were retrospectively analyzed.
RESULTSThree mucoepidermoid carcinomas were located in the main bronchus, 4 in segmental bronchus, and 1 in peripheral lung. Intrabronchial nodule or mass with smooth or lobulated margin and punctuate or strip calcification (n = 2) was the main CT feature. The tumor showed moderate to significant enhancement after the administration of contrast medium. Three adenoid cystic carcinomas involved trachea, and 2 involved the main and lobular bronchi. The main CT features were diffuse or circumferential irregular thickness of the wall, distorted lumen, and nodule protruding into the lumen, and the longitudinal extent of the tumor was greater than its transverse axis.
CONCLUSIONThe CT findings of primary salivary gland-type lung cancer are rather specific and may provide helpful information for the clinical diagnosis and treatment.

OBJECTIVETo evaluate the prevalence of infection with Borna disease virus (BDV) in Chinese patients with chronic fatigue syndrome (CFS) and control subjects, and to discuss the etiological association between CFS and infection with BDV.
METHODSThe CDC (1994) diagnostic criteria for CFS were used for case definition. Sixty-one patients suffered from CFS were from 11 Provinces in China. To detect the antibody against BDV-p24 on the plasma samples from all cases and 73 healthy control subjects by Western-blotting analysis.
RESULTS7 of the sixty-one cases and 0 of the controls were sero-positive for BDV-p24 antibody, there was a statistical significant difference between the two groups (11.48% vs 0%; P less than 0.010).
CONCLUSIONChinese patients with CFS showed sero-positive identifying BDV infection, by comparison, anti.BDV-p24 antibody prevalence in patients was significantly higher than in controls. An etiological association may exist between CFS and BDV infection.

OBJECTIVETo access the efficacy of posterior short-segment fixation for single level thoracolumbar burst fractures without spinal injury using CYL-pedicle screw.
METHODSFrom September 2007 to December 2009, 74 cases who underwent posterior short-segment fixation for single level thoracolumbar burst fractures (Denis burst fracture type A, B, C) without spinal injury were analyzed retrospectively. There were 53 male and 21 female, mean age was (39 ± 15) years. Neither of them treated with direct decompression, grafting or fusion. Changes in the anterior vertebral height ratio, vertebral wedge angle, Cobb angle, regional angle were measured preoperatively, postoperatively, before implant removal, and at final follow-up to find the statistic difference. Pain status and work status were evaluated using Denis criterion. The incidence of incision infection, screw breakage, iatrogenic spinal injury were recorded as well.
RESULTSThe time of follow-up was (20 ± 11) months, no significant change was noted in anterior vertebral height ratio and vertebral wedge angle (P > 0.05). A significant loss was noted in Cobb angle and regional angle, which were 9.8° ± 5.1° and 9.1° ± 4.8° respectively (t = 2.48 and 3.41, P < 0.05). Comparing with the patients with Cobb angle > 20°, the patients with Cobb angle ≤ 20° had better pain scale rate (χ(2) = 4.16, P = 0.04) and work scale rate (χ(2) = 24.34, P < 0.01). There were incision infection in 1 case, screw breakage in 1, screw loose in 1, and no iatrogenic spinal injury.
CONCLUSIONSCYL-pedicle screw could be successfully used in posterior short-segment fixation for single level thoracolumbar burst fractures without spinal injury based on radiographic and clinic outcomes.
