OBJECTIVETo study the imaging findings outcome of the percutaneous laser disc decompression (PLDD) and evaluate the middle-term safety and efficacy of PLDD.

METHODSThe imaging data of 22 cases suffered cervical spondylosis or lumbar spondylosis and treated by PLDD more than 3 years were retrospectively reviewed. To observe the intervertebral space of the invasive disc and the intervertebral disc hernia before and after the operation on the lateral projection of X-ray and the axial view of the MRI. To make a statistical analysis of the data.

RESULTSThere was no obvious change of disc height involving the anterior disc height, the intermediate disc height and the posterior disc height after the PLDD at the final follow-up (P > 0.05). At last time follow-up, the Sagittal Index (SI) are 0.10 - 0.54 and 0.06 - 0.39 before and after the PLDD in the treatment of cervical vertebra. The statistical difference were significant (P < 0.05). In lumbar vertebra, the SI is 0 - 0.71 and 0 - 0.48 disc before and after the PLDD. The statistical difference were very significant (P < 0.01).

CONCLUSIONSThe PLDD will not destroy the intervertebral space of the cervical and lumbar vertebra obviously; moreover, it can effectively reduce the disk hernia. The PLDD is a safe and effective Mini-invasive surgery for cervical vertebra and lumbar vertebra diseases.

OBJECTIVETo explore the mechanism and feasibility of the supinator syndrome evoked embitterment test from anatomy and clinic.

METHODS25 cases of The supinator syndrome were reviewed. 18 of them were male and 7 were female. Drop finger deformation were apparent in 25 cases and The supinator syndrome evoked embitterment test was positive for All patients. Operative neurolysis was done in 8 cases, conservation treatment 17 cases; 92 cadaver upper extremities were dissected for a study the relationship between supinator tunnel and posterior interosseous nerve.

RESULTS22 cases had been followed up for an average of 9 months. 16 cases had a full recovery and 6 cases, a partial recovery. the anatomical study shows that The posterior interosseous nerve was compressed by Forhse arcade and the distal border of the supinator muscle during passive pronation forearm.

CONCLUSIONThe supinator syndrome evoked embitterment test was a new test for the diagnosis of supinator syndrome, it was found to be more sensitive and specific than the others test.

OBJECTIVETo explore the distribution and influence factors of protein C (PC), protein S (PS) and antithrombin (AT) activities and to determine the prevalence of their deficiencies in the Chinese Han healthy population.

METHODSHealthy volunteers including blood donors and individuals for routine check-up were recruited from 4 Chinese medical centers. The plasma levels of PC, PS and AT activities were measured. The plasma levels of activities were measured by chromogenic substrate assay (AT and PC) and clotting assay (PS).

RESULTSA total of 3493 healthy Chinese adults had been recruited in this study. Males had higher PS and PC activities than females, especially for PS (P < 0.01). PC activities increased with age in both sexes but decreased in men after 50 years old. There was no significant change with age were of PS in 50 years old, while there was a decline in males and a rise in females above 50 years old. AT tended to increase with age in women but decreased with age in men after 50 years old. Based on the age and gender, the general prevalence of PC, PS and AT deficiencies in the general Chinese Han population were 1.15%, 1.49% and 2.29%, respectively.

CONCLUSIONPC, PS and AT activities have correlation with age and gender in Chinese Han population. Reference range should be laid down and deficiencies should be identified

OBJECTIVE: To investigate the effect of Yinlai Decoction (YD) on the microstructure of colon, and activity of D-lactic acid (DLA) and diamine oxidase (DAO) in serum of pneumonia mice model fed with high-calorie and high-protein diet (HCD). METHODS: Sixty male Kunming mice were randomly divided into 6 groups by the random number table method: normal control, pneumonia, HCD, HCD with pneumonia (HCD-P), YD (229.2 mg/mL), and dexamethasone (15.63 mg/mL) groups, with 10 in each group. HCD mice were fed with 52% milk solution by gavage. Pneumonia mice was modeled with lipopolysaccharide inhalation and was fed by gavage with either the corresponding therapeutic drugs or saline water, twice daily, for 3 days. After hematoxylin-eosin staining, the changes in the colon structure were observed under light microscopy and transmission electron microscope, respectively. Enzyme-linked immunosorbent assay was used to detect the protein levels of DLA and DAO in the serum of mice. RESULTS: The colonic mucosal structure and ultrastructure of mice in the normal control group were clear and intact. The colonic mucosal goblet cells in the pneumonia group tended to increase, and the size of the microvilli varied. In the HCD-P group, the mucosal goblet cells showed a marked increase in size with increased secretory activity. Loose mucosal epithelial connections were also observed, as shown by widened intercellular gaps with short sparse microvilli. These pathological changes of intestinal mucosa were significantly reduced in mouse models with YD treatment, while there was no significant improvement after dexamethasone treatment. The serum DLA level was significantly higher in the pneumonia, HCD, and HCD-P groups as compared with the normal control group (P<0.05). Serum DLA was significantly lower in the YD group than HCD-P group (P<0.05). Moreover, serum DLA level significantly increased in the dexamethasone group as compared with the YD group (P<0.01). There was no statistical significance in the serum level of DAO among groups (P>0.05). CONCLUSIONS YD can protect function of intestinal mucosa by improving the tissue morphology of intestinal mucosa and maintaining integrity of cell connections and microvilli structure, thereby reducing permeability of intestinal mucosa to regulate the serum levels of DLA in mice.
