AIM: To evaluate the effect of hyaluronate based gel (HAbg) in prevention of pleural thickening and adhesion in patients with tuberculous pleural effusions. METHODS: 52 patients with middle amount of tuberculous thoracic fluid accumulated, fluid bound, and pleura thickened more than 2 mm were divided into two groups at random. The patients of two groups were all given standard treatments with anti tuberculous drugs. HAbg was injected into intra thoracic cavity in treatment group (27 patients), while saline (NS) was introduced into intra thoracic cavity in control group (25 patients). Before and after HAbg injection, thoracic fluid routine and protein quantification were tested respectively. Pulmonary functions were measured after 2 weeks and 3 months of thoracic fluid absorption. RESULTS: Patients treated with HAbg showed significantly thinner pleura, lower proteins and white blood cell count in thoracic fluid, and higher FEV1% and FVC% for their pulmonary function in comparison with the control group. CONCLUSION: Intrathoracic injection of HAbg can prevent pleural thickening and improve the lung function in patients with excess fluid of tuberculous thoracic cavity.

Objective To assess the efficacy of alginate dressing in fat liquefaction of abdominal incision. Methods 76 patients with fat liquefaction of abdominal incision in our hospital were divided into the experimental group (42 patients) and the control group(34 cases). Both groups were given preventive antibiotics. The penetration, times of dressing change, interval of dressing change, healing cost, wound infection, period Ⅱ wound healing, time for the medicine to start working, time of healing were observed in the two groups. All results underwent t test and χ2 test. Results No distinct difference of healing cost between the two groups was observed. The experimental group treated with alginate dressing was better than the control group in other clinical indexes after treatment. Conclusions Application of alginate dressing is beneficial to management of fat liquefaction of abdominal incision and reduce time of healing and hospital stay.

Objective To explore the role of ubiquitin-proteasome pathway for the gelsolin protein degradation in pancreatic cancer.Methods Pancreatic cancer cell lines BxPC-3 and PANC-1 were first treated with specific 26s proteasome inhibitor lactacystin.Immunoblots of cell lysates were probed for gelsolin expression.To determine whether gelsolin was conjugated to ubiquitin,proteins extracted from the cells with or without lactacystin were immunoprecipitated with anti-gelsolin antibody,followed by Western blot analysis.Results The expression of gelsolin protein increased obviously after treatment with lactacystin in BxPC-3 cells for 12 h.Using anti-gelsolin antibody to immunoprecipitate gelsolin protein and followed by Western blot using anti-ubiquitin monoclonal antibody,it was found that inhibition of proteasome pathway by lactacystin resulted in accumulation of ubiquitylated forms of gelsolin protein.In PANC-1 cell line,there was no significant changes of gelsolin after treatment with lactacystin.Conclusion Ubiquitin-proteasome dependent degradation may be an important regulatory mechanism for gelsolin down-regulation in pancreatic cancer cells.

Objective Stathmin, a microtubule-destabilizing protein , has high expression in esophageal squamous cell carci-noma(ESCC), while taxol is a common chemotherapy microtubule-targeted drug for esophageal cancer .This study aimed to investigate the impact of stathmin expression and its influence on taxol sensitivity in ESCC . Methods We established 2 cell models with ST-MN1 gene overexpression in KYSE 510 and KYSE 170 cell lines, including KYSE 510-Stathmin, KYSE 170-Stathmin, KYSE 510-Control and KYSE 170-Control.MTT assay and colony formation were applied to compare the taxol sensitivity between experimental group and control group .Flow cytometry was used to measure the apoptosis of KYSE 510-Stathmin and KYSE 510-Control after taxol treatment.Western blot was used to test the changes of related factors to apoptosis and autophagy . Results ①Stathmin protein ex-pressions in KYSE 510-Stathmin and KYSE 170-Stathmin cells were higher than those of control cells (P<0.01).② The percentages of inhibition were significantly decreased in KYSE 510-Stathmin and KYSE 170-Stathmin cells 24 h after 50, 100,250 nmol/L taxol treat-ment compared with KYSE 510-Stathmin cells(P <0.01).③The percentages of inhibition were significantly reduced in KYSE 510-Stathmin and KYSE 170-Stathmin cells after 250 nM taxol treatment for 24, 48, 60 h (P<0.01).④After taxol treatment,the number of colony formation in KYSE 510-Stathmin cells was higher com-pared with KYSE 510-Control cells (P<0.01).⑤The percentage of cell apoptosis in KYSE 510-Stathmin was significantly lower than that of KYSE 510-Control cells by flow cytometry (11.90%±0.78%vs 29.63%±3.26%, P<0.05).Western blot showed the ap-optosis of associated proteins such as the activation of Caspase 8 and Caspas9. Conclusion The result indicates that overexpression of stathmin inhibits taxol sensitivity in ESCC cell lines .

Objective To understand the relationship between the infants′iron-deficiency anemia and the dependents′KAP (knowledge,attitude,practice)of iron nutrition,and to provide a theoretical support for the prevention and cure of the infants′iron-eficiency anemia.Methods A total of 960 infants,aging from 6 months to 36 months,were randomly chosen as samples at the child care clinics in Wuhan while they were doing their routine health check-up there.Their hemoglobin was examined.Their dependents were asked to fill in questionnaires about KAP of iron nutrition.Results The ratio of anemia in infants in Wuhan is 26.6%.The ra-tio difference of different age groups has statistical significance(P <0.05).The dependents′KAP of iron nutrition is in direct pro-portion to their educational level and family income.The ratio of anemia in infants is in inverse proportion to their dependents′edu-cational level and family income.The dependents′knowledge,attitude and practice of iron-intake were positively related.The aver-age score of guardian nutrition knowledge(K)was (11.96±3.77)points,the average score of attitude(A)was (7.09±2.80)points while the average score of feeding practice(P)was (18.05±3.60)points.Conclusion Much publicity should be given to the knowl-edge of iron nutrition and it should be conducted from various perspectives,in order to improve the cognitive level of the depend-ents′knowledge of iron nutrition and to lower the ratio of anemia in infants.

Objective:To compare the volatile constituents in mugwort leaves produced in Qichun, Hubei Province and Nanyang, Henan Province.
Methods:The volatile constituents were extracted using headspace heating and analyzed using gas chromatography-mass spectrometry (GC-MS). Then a qualitative analysis was made according to the standard database provided by the National Institute of Standards and Technology (NIST) and the relative contents of each constituent were calculated using the peak area normalization method.
Results:A total of 59 compounds were identified from the mugwort leaves from Qichun and 51 compounds were identified from the mugwort leaves from Nanyang. These mainly include monoterpenoids, sesquiterpenoids, CxHyOz and other compounds involving the aldehyde, ketone, alkane and benzene. The mugwort leaves from Qichun and Nanyang share 32 common volatile constituents. The chromatographic peak area of identified compounds accounting for 96.38% of GC-MS total chromatographic peak areain Qichun mugwort leaves, versus 95.54% of that in Nanyang mugwort leaves.
Conclusion:The headspace heating extraction combined with GC-MS technology can evidently display similarities and differences of volatile constituents in mugwort leaves produced in different areas and thus provide scientific basis for the quality and screening of mugwort leaves.

To obtain higher potency and specificity, a series of 7-alkoxy analogues of illudalic acid was synthesized on the base of structure-activity relationship (SAR). All of these compounds exhibited submicromolar inhibition of the enzyme when tested against human leukocyte common antigen-related phosphatase (LAR) (for example, for 15e, IC50 = 180 nmol x L(-1)). They represent the most potent small-molecule inhibitors of LAR so far. These analogues also display excellent selectivity for LAR over other protein tyrosine phosphatases (PTPs) except for the highly homologous PTPsigma. The compound 15f is of 120-fold selectivity for LAR versus PTP-1B inhibition. The development of potent enzyme-specific inhibitors is so important that they may serve both as tools to study the role of LAR and as therapeutic agents for treatment of type II diabetes.
