Objective To investigate the clinical application of the combined the anterior malleolus flap and anterior tibia flap. Methods Based on the dissection of the perforating branches of anterior tibial artery on the middle and inferior section, the combined the anterior malleolus flap and anterior tibia flap was designed to repair the necrotic skin of anterior foot for 5 patients. The sizes of the flaps ranged from 17 cm×10 cm-10 cm× 5 cm. And the area of the flap was from tibial tuberosity(upper bound) to the line between internal malleolus and external malleolus (lower bound), and from the median line of one side of leg to the other side. Results Postoperatively, all flaps survived, and the primary healing of transplanted skin in donor site was achieved. The texture of flaps were excellent, the phenomenon of abrasion did not happen, and the clinical therapeutic efficacy was satisfactory after a follow up of 2-24 months. Conclusion It's a good method that combined the anterior malleohls flap and anterior tibia flap, which not only could enlarge the area of the flap but also has reliable blood supply, in repair of large size skin defect of anterior foot.

ObjectiveTo observe the effects of Chinese Traditional Medical therapy of supplementing Qi, nourishing Yin and strengthening genuine Qi on hemiplegia after stroke.Methods102 cases of hemiplegic patients were divided into 2 groups randomly, observational group (52 cases) and control group (50 cases), who were all treated with routine medicine and early rehabilitation. Observational group accepted Shenqi Fuzheng Injection or Shengmai Injection according to their syndrome for 28 days. Before and after treatment (within 3 days), simple Fug-Meyer Assessment Scale, modified Barthel index and gait analysis were used to evaluate the function of motor, activity of daily living (ADL) and walking.ResultsBoth groups improved their function of upper and lower limb's movement, ADL and walking significantly (P<0.001) after treatment. Compared with the control group, except for motor of upper limps, the patients in observational group improved their function more significantly (P<0.05).ConclusionChinese Traditional Medical therapy of supplementing Qi, nourishing Yin and strengthening genuine Qi may help the recovery of hemiplegia after stroke.

Objective: To compare tea polysaccharides(TPS) characteristics and their role in scavenging free radicals and reducing blood glucose(BG) in diabetic mice(DM). Methods: TPS was extracted from green,Oolong and black tea which were made from the same fresh leaves from Hubei,Fujian and Yunnan. Then the recovery rate of TPS, contents of neutral sugar, uronic acid and protein were analysed, and scavenging rate of -2Oand 稯H in vitro and hypoglycemic effect were also determined. Results: 1. The yield and contents of neutral sugar, uronic acid and protein of green tea TPS were the highest, and those of black tea TPS were the lowest. Oolong tea TPS acted the best in scavenging-2O and 稯H . 2. The hypoglycemic effect of TPS from Hubei tea was the best . The effect of TPS extracted from semi-fermented Oolong tea and fermented black tea was better than that of non-fermented green tea. 3. There were obvious differences in yield, free radical scavenging rate and effect of reducing BG among TPS extracted from tea in different regions. TPS extracted from Fujian tea had the best effect in reducing BG,but that from Yunnan tea had not. Conclusion: There was remarkable effect of region and process on physico-chemical characteristics,effect of scavenging radical and reducing blood sugar TSP.

In this study, hydrophilic matrix sustained release tablets of total lactones from Andrographis paniculata were prepared and the in vitro release behavior were also evaluated. The optimal prescription was achieved by studying the main factor of the type and amount of hydroxypropyl methylcellulose (HPMC) using single factor test and evaluating through cumulative release of three lactones. No burst drug release from the obtained matrix tablets was observed. Drug release sustained to 14 h. The release mechanism of three lactones from A. paniculata was accessed by zero-order, first-order, Higuchi and Peppas equation. The release behavior of total lactones from A. paniculata was better agreed with Higuchi model and the drug release from the tablets was controlled by degradation of the matrix. The preparation of hydrophilic matrix sustained release tablets of total lactones from A. paniculata with good performance of drug release was simple.

Objective To investigate the development,prevention and treatment of primary or secondary acute adrenal hypofunction with hyponatremia. Methods Forty-eight cases of acute adrenal hypofunction with hyponatremia from 1970 to 2006 were collected and divided into groups of hydrocephalus(n=23) and non-hydrocephalus(n=25).The causes,inducing factors,clinical manifestations,laboratory indexes,treatment and outcomes of the two groups were retrospectively analysed.In addition,another 48 patients with chronic adrenal hypofunction and 48 normal controls were included in the study. Results Infection constituted the most common inducing factor for the 48 cases of acute adrenal hypofunction with hyponatremia.Both natremia and urine cortisone were significantly lower in hydrocephalus and non-hydrocephalus patients than those in chronic adrenal hypofunction and controls(P

OBJECTIVEGas chromatography (GC) was used to investigate the cellular fatty acid (CFA) composition of 141 Acinetobacter baumannii and 32 A. calcoaceticus isolates from different locations in China and to find chemical markers to differentiate these two closely related bacteria.

METHODSWhole cell fatty acid methyl esters (FAMEs) were obtained by saponification, methylation, and extraction for GC analysis, followed by a standardized Microbial Identification System (MIS) analysis.

RESULTSAll A. baumannii and A. calcoaceticus strains contained some major fatty acids, namely, 18:1 ω9c, 16:0, Sum In Feature 3, 12:0, 17:1ω8c, 3-OH-12:0, 17:0, Sum In Feature 2, 2-OH-12:0, and 18:0 compounds. Although most of the total CFAs are similar between A. baumannii and A. calcoaceticus strains, the ratios of two pairs of CFAs, i.e., Sum In Feature 3/18:1 ω9c versus 16:0/18:1 ω9c and Sum In Feature 3/18:1 ω9c versus unknown 12.484/18:1 ω9c fatty acids, could differentiate these two closely related bacteria. A. baumannii could be easily classified into two subgroups by plotting some ratios such as Sum In Feature 3/16:0 versus 17:0 and Sum In Feature 3/2-OH-12:0 versus 17:0 fatty acids.

CONCLUSIONThe ratios of some CFAs could be used as chemical markers to distinguish A. baumannii from A. calcoaceticus.

OBJECTIVETo evaluate application of the sponge of demineralized bone matrix (SDBM) in tissue engineering of bone.

METHODSSDBM was prepared from long bone of rabbits. Bone marrow cells were flushed from the bone shaft of femurs of a two-month-old New Zealand white rabbit. After the cells were cultured for 9 days, the flasks were added into dexamethasone (10(-8) mol/L), beta-glycerophosphate sodium (10 mmol/L) and L-ascorbic acid (50 micrograms/ml). After 5 weeks, the cultured cells were collected and marked by 5-Bromo-2'-dexyouridine (BrdU). The grand sum of cells seeded on a piece of SDBM was about (4-6) x 10(6). The composites of cells and SDBM (tissue engineered chip, TEC) were implanted into muscles and bone defects of radius in rabbits. A standard procedure was applied to make a 10 mm long defect bilaterally in the radius of nine skeletally mature male New Zealand white rabbits. All of the 18 defects were randomly divided into three groups: group I, six defects were grafted by TEC; group II, six defects were grafted with SDBM alone; group III, six defects were empty.

RESULTSThe results of radiographic and histological evaluation showed that all of the defects were repaired in group I and group II at 6 weeks, none of the defects was repaired in group III. The results of BrdU staining showed that the staining was positive in group I, but negative in group II. Biomechanical test showed that the compressive ultimate strength (CUS) of new bone in TEC implanted group was comparable with normal radius (P = 0.623) and in SDBM implanted group was significant lower than normal radius (P = 0.038).

CONCLUSIONSThe TEC can form cartilage and bone tissue in muscles and repair segmental bone defects. SDBM is a kind of effective natural scaffold in tissue engineering of bone.

Objective To determine the urinary iodine level of people in Yunyang and Bishan County of Chongqing and explore into its influencing factors. Methods Using multistage cluster stratified simple random sample method, Yunyang and Bishan County were chosen as research spots, then thirty children aged 8-10 in each 3 primary school of the 2 counties were selected using stratified randomization sampling method to inspected their urine and household salt for iodine and the iodine content in drinking water. Results Five hundred and seventy-one urine samples were inspected and the urinary iodine median was 261.47 μg/L. 5.78% (33/571) and 37.48%(214/571) of samples had an urinary iodine median less than 100 μg/L and more than 300 μg/L. The urinary iodine median of Yunyang County was higher than that of Bishan (H = 7.42, P < 0.01). The iodine salt coverage rate, the qualified rate and edible qualified iodine salt rate respectively were 99.64%(554/556), 94.22% (522/554) and 93.88% (522/556) in 556 samples of family table salt. Eighty-seven samples of drinking water were inspected, resulting an averaged iodine content of 8.81 and 2.97 μg/L, respectively in the 2 counties. Conclusions The 2 counties are all the area of iodine deficiency. The urinary iodine level, although meeting the demand of eliminating iodine deficiency diseases, is a little bit higher given that iodized salt of present doage has been taken for a long time. The content of iodized salt should be adjusted accordingly.
