Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

The degQ gene, amplified from Bacillus subtilis by PCR, was cloned to pUBS (sucrose induced secretion vector). After transformed into DB403, recombination named DB403(pUBSD) was formed. The results of the fermentation showed that degQ gene enhanced the expression of B. subtilis fibrin enzyme. The activity of the enzyme was increased to 2.2 times as the original one. In this article, the effects of different conditions, such as different kinds of sugar, different concentration of sucrose and different induced time were also be investigated and compared.

Objective To investigate the efficacy and toxicity of postmastectomy hypofractionation radiotherapy in patients with high-risk breast cancer. Methods Postmastectomy radiation of 43.5 Gy in 15 fractions of 2.9 Gy over 3 weeks was delivered to 38 patients with breast cancer. The incidence of acute radi-ation toxicity and lecoregional recurrence was evaluated. Results With a median follow up of 13 months, all patients were alive. No patient had locoregional recurrence within radiation field. Five (13%) had dis-tant metastases. Five (13%) developed grade 3 radiation dermatitis at 2 to 3 weeks after the course of radia-tion. Three (8%) had grade 2 radiation pneumonitis. Conclusions Hypofractionation radiation of 43.5 Gy in 15 fractions of 2.9 Gy over 3 weeks is effective in the near time for patients with high-risk breast cancer after mastectomy, and the acute toxicities are tolerable.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

Objective: To study the effects of TNFα on wound healing. Methods: The skin lesion and incisions were made on mice and rhTNFα was applied in both skin lesion and incision. Tissue strips were evaluated for tensiometry and histologic features after healing. Results: It was found that rhTNFα markedly improved wound healing both in skin lesion and incision wound model, it also markedly enhanced the breaking strength of treated incision and increased wound cellularity in rh TNF α treated groups. Conclusion: The results suggest that TNFα play an important role in regulating inflammatory reactions of local injured tissues and it may improve the functions of fibroblasts, mononuclear phagocytes and endothelial cells. rhTNFα of suitable doses can promote wound healing. This shows that TNFα, as a wound healing promoter, has the potentials for clinical application.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.
