Objective: To prepare a composite membrane by chitosan/β-sodium glycerophosphate(CS/β-GP) thermosensitive hydrogel combined with stromal cell derived factor-1(SDF-1) and observe its biological characteristics in vitro. Methods: Different doses of SDF-1 were added into CS/β-GP solution and then the thermosensitive gel time was measured. The SDF-1/CS/β-GP solution was membrane paved and dried to prepare composite membranes. The morphological characteristics were observed by scanning electron microscope(SEM). Composite membranes were placed into cell culture medium, and the supernatant(n=3) was extracted after standing at 6, 12, 24, 36, 48, 60 h, respectively. The concentration of SDF-1 in the solution was measured. Bone mesenchymal stem cells(BMSCs) were cultured in the Transwell room, and the composite membranes containing different concentrations of SDF-1 were placed in the lower chamber. There were four groups(n=3): Group M0 used CS/β-GP membrane(control group), Group M1, M2, M3 used SDF-1/CS/β-GP membrane(SDF-1 was 100, 200, 400 ng/mL respectively). After culture for 6, 12 and 24 h, the cells under the membrane were preserved and Giemsa stained and counted. The absorbance(OD) value was measured by MTT method to calculate the cell proliferation rate. SPSS 19.0 was used for multi-factor analysis of variance. Results : After adding a certain amount of SDF-1 into CS/β-GP solution, the gel time did not change significantly(P>0.05). The SDF-1/CS/β-GP membrane was translucent and porous at 37 ℃. In this experiment, the volumic mass of SDF-1 released by SDF-1/CS/β-GP composite membrane increased gradually with the experimental time(P<0.01). Transwell cell chemotaxis test showed that the number of BMSCs cells with directional migration increased with the prolongation of observation time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). In MTT test, the OD value of migration cell solution increased with the prolongation of time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). Conclusion The SDF-1/CS/β-GP composite membrane has a porous structure and biological activity of chemotactic BMSCs directional migration. It is a potential membrane for guided tissue regeneration.

Objective To investigate the effects of Rehmannia and Storesin (RS) on early hepatic encephalopathy (HE) in rat model.Methods HE rat model was induced by CCl4 intragastric administration. The effects of RS on serum nitric oxide (NO) and nitric oxide synthase(NOS) as well as hippocampal tumor necrosis factor α (TNF-α) level of animals were evaluated in 3 dose groups. Lactulose was usedas the positive group. Results The serum NO and NOS as well as hippocampal TNF-α level of the model rats were significantly increasedcompared with that in control animals (P<0.01). The RS high dosage treatment could significantly decrease the levels of those indexes (P<0.01). Conclusion Rehmannia and Storesin is effective on early HE by decreasing the level of serum NO and NOS as well as hippocampalTNF-α.

Objective To assess the effects of Rehmannia and Storesin (RS) on peripheral-type benzodiazepine receptors (PBRs) in early hepatic encephalopathy (HE) rats. Methods CCl4 was used to induce the HE model. The benzodiazepine binding sites of PBRs in rats cortex were studied using the specific ligands [3] PK11195. Lactulose was used in the positive medicine group, and the treatment groups received different dosages of RS. Results The specific binding and the Bmax value of [3] PK11195 both significantly increased in the model group than in the control group (P<0.01). The specific binding decreased in the medium dosage group and the high dosage group than in the model group (P<0.05), and the Bmax value of [3] PK11195RS-H decreased in the high dosage group than in the model group (P<0.01).

Objective: To evaluate the safety and feasibility of Da Vinci robot in the treatment of thyroid cancer with hyperthyroidism via bilateral axillo-breast approach (BABA). Methods: The clinical data of 21 patients with thyroid cancer complicated with hyperthyroidism who received thyroidectomy + central lymph node dissection and(or)neck lymph node dissection using the Da Vinci through axillo-bilateral-breast approach in the thyroid and breast surgery of the 960th Hospital of the PLA Joint Logistics Support Force, from February 2014 to February 2019 were analyzed retrospectively. The clinical data of 21 patients were used as observation group, including 5 males and 16 females, aged (46.03±3.08) years. At the same period, 19 patients with the thyroid cancer complicated with hyperthyroidism who underwent traditional open surgery were selected as the control group, including 5 males and 14 females, aged (47.06±2.03) years. The t test, rank sum test, and χ² test were used to compare the operation time, postoperative hospital stay, postoperative drainage volume, postoperative pain (VAS), cosmetic outcome satisfaction, and related surgical complications between the two groups. Results: All the patients of the two groups completed the operation successfully. The operation time of the observation group was longer than that of the control group [(191.12±3.17) vs (145.37±6.37) min, P<0.05]; The postoperative pain degree score of the observation group was lower than that of the control group [(3.40±1.12) points vs (5.10±1.19) points, P<0.05]. The cosmetic effect score of the observation group was better than that of the control group [(9.10±3.03) points vs (5.05±1.02) points, P<0.05]. There were no significant differences in the amount of intraoperative blood loss, mean postoperative drainage, postoperative hospital stay, central lymph node metastasis and complication rate between the two groups (P>0.05). There was no significant difference in Tg level and recurrence rate between the two groups (P>0.05). Conclusion Da Vinci robotic assisted treatment for thyroid cancer with hyperthyroidism is safe and feasible, which with good cosmetic and privacy protection effects.

Recombinant plasmid pICG was constructed by replacing the internal fragment of a-acetohydroxyacid synthase (AHAS) gene (ILV2) with a copy of gamma-glutamylcysteine synthetase gene (GSH1) and copper chelatin gene (CUP1) from the industrial brewing yeast strain YSF31. YSF31 was transformed with plasmid pICG linearized by Kpn I and Pst I. A recombinant strain with high-glutathione and low-diacetyl production was selected. The results of fermentation in 100-L bioreactor showed that the lagering time of beer produced for recombinant strain T2 was shortened by 3 days and the shelf life of the beer was prolonged about 50%. It may be more acceptable for the commercial application, as it does not contain foreign DNA.

OBJECTIVETo observe the difference in the efficacy on the symptoms of bronchial asthma at the chronic persistent stage between acupoint heat-sensitive moxibustion and western medicine with Seretide.

METHODSSixty-four cases were randomly divided into a heat-sensitive moxibustion group (32 cases) and a western medication group (32 cases). In the heat-sensitive moxibustion group, the sensitized points located between Feishu (BL 13) and Geshu (BL 17) or in the region 6-cun lateral from the 1st and the 2nd intercostal spaces of the chest were selected. The heat-sensitive moxibustion was adopted, continuously for 8 days, once per day. In the later 22 days of the 1st month, 12 treatments should be ensured. Two months later, 15 treatments should be guaranteed each month. The time of each treatment was 30 to 90 min. Totally 50 treatments were required. In the western medication group, Seretide inhaler was adopted, one inhalation each time, twice per day, for 3 months totally. The asthmatic symptoms were scored for the patients in two groups and the comparison was made between the two groups.

RESULTSAfter 3 months of treatment, the asthmatic symptom scores were all improved for the patients in the heat-sensitive moxibustion group and the western medication group as compared with those before treatment (both P < 0.05). In 6 months of follow-up visit, the asthmatic symptom scores in the heat-sensitive moxibustion group were stable, but those in the western medication group were reduced, there was significant difference between the two groups (P < 0.05).

CONCLUSIONThe acupoint heat-sensitive moxibustion effectively relieves the clinical symptoms for the patients with bronchial asthma at the chronic persistent stage. Its efficacy is similar to that of Seretide inhaler. But the long-term efficacy of the heat-sensitive moxibustion is much better.

OBJECTIVE: To determine the therapeutic effect of spirulina platensis in allergic rhinitis (AR). METHODS: Ovalbumin sensitized white rats used as AR animals were treated with spirulina platensis (SPP). At the end of the treatment, the differences in the behavior science were observed; the changes in the nasal mucosa and mast cell degranulation were studied pathologically; and the levels of serum histamine and total immunoglobulin (Ig) E were determined by enzyme-linked immune sorbent assay. RESULTS: The behavior science score of the SPP treatment group was lower than that of the negative control group (P < 0.01 ) ; inflammatory reaction of nasal mucosa in the SPP treatment group were remarkably relieved; the number of nasal mucosa mastocyte and mast cell degranulation in the SPP treatment group were lower than that of the negative control group (P <0.01 ). The levels of serum histamine and total IgE in the SPP treatment group were lower than that of the negative control group (P <0.01 ). It had no significant difference in the positive control group and the SPP treatment group and the blank control group (P > 0.05 ). CONCLUSION Spirulina platensis can prevent and treat AR in rats, which implies the possibility of using spirulina platensis for AR patients in the future.
