Objective: To examine the preliminary clinical efficacy of Chinese magnetic sphincter augmentation (MSA) in the treatment of gastroesophageal reflux disease (GERD). Methods: According to the enrollment criteria for the MSA developed by ShengJieKang Co. and Shanghai Chest Hospital (SS-MSA) clinical trial, a total of 19 GERD patients were treated with SS-MSA from August 2018 to January 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University. The majority of registered cases were male patients with age of (32.2±7.3) years (range: 22 to 50 years), height of (170.7±6.2) cm (range: 160 to 179 cm) and weight of (65.2±10.3) kg (range: 47.5 to 90.0 kg). SS-MSA was implanted via laparoscopy. The major evaluation indexs of postoperative efficacy were the total time of acid exposure within 24 hours and the total number of reflux. Secondary efficacy indicators included: (1) evaluation of the average daily dose of proton pump inhibitor medications; (2) the score of GERD health related quality of life questionnaire (GERD-Q) before and after MSA implantation. Paired design t-test was used to evaluate the efficacy of the SS-MSA. Results: A total of 19 patients underwent SS-MSA surgery successfully. The history of the GERD were 19 (54) months (M(Q(R))). The operation time was 63 (22) minutes and the in-hospital stay was 3 (2) days. No obvious surgical complications occurred. Postoperative adverse events included 14 cases with mild to moderate dysphagia exited after surgery, gradually eased within 1 to 3 months, 1 case with the removal of the device after 1 month of severe swallowing difficulties, 1 case of diarrhea. No corrosion, perforation, displacement occurred. The GERD-Q score (11.0(4.5) vs. 6(1.0), t=4.274, P=0.013), 24-hour acid exposure time (6.2(4.8)% vs. 0.1(0.9)%, t=5.814, P=0.004), and Demeester score (23.72(16.20) vs. 0.96(3.10), t=6.678, P=0.003) were significantly decreased 1 year after surgery(n=5). Proton pump inhibitor reuse rates were 6/18, 5/15, 3/10, and 1/5 in 1, 3, 6 and 12 months after the operation, respectively. Conclusions: SS-MSA implantation is feasible and safe with short hospital stay and rare perioperative complications. The preliminary results is good after 1 year follow-up. It could be expected to be an ideal substitutive for future GERD treatment.

Algae is a well-known organism that its characteristic is prominent for biofuel production and wastewater remediation. This critical review aims to present the applicability of algae with in-depth discussion regarding three key aspects: (i) characterization of algae for its applications; (ii) the technical approaches and their strengths and drawbacks; and (iii) future perspectives of algae-based technologies. The process optimization and combinations with other chemical and biological processes have generated efficiency, in which bio-oil yield is up to 41.1%. Through life cycle assessment, algae bio-energy achieves high energy return than fossil fuel. Thus, the algae-based technologies can reasonably be considered as green approaches. Although selling price of algae bio-oil is still high (about $2â¯L-1) compared to fossil fuel's price of $1â¯L-1, it is expected that the algae bio-oil's price will become acceptable in the next coming decades and potentially dominate 75% of the market.

AIM: To explore the therapeutic effect and the mechanism of Chinese herbs on antiphospholipid syndrome (APS) by observing the effect of Salvia miltiorrhiza Bunge injectio (SmBI) on anticardiolipin antibody (aCL) induced by beta2 glycoprotein I (beta2-GP I). METHODS: Sixty female mice randomly fell into 6 groups: group A, B, C, D was injected through abdominal cavity with different dosage of SmBI daily; after 14 d, group A, B, C, E was immunized with 150 microg of purified human beta2-GP I in complete Freund's adjuvant subcutaneously; group F as control. The titre of aCL were detected by enzyme linked immunosorbent assay; subsets of T cell were grouped by streptavidin-biotin complex technique; and the activity of IL-2 was measured by MTT chromatometry. RESULTS: (1) Compared with group E, the absorbance (A) of aCL in group A, B, and C was decreased (P < 0.05 or P < 0.01). By linear correlation, the dosage is negatively correlated with the A values of aCL in 1, 2, and 3 weeks (P < 0.01). (2) Compared with group E, TH/TS ratio was reduced in group A, B, and C (P < 0.05 or P < 0.01); there is no significant differences between group D and F (P>0.05). By linear correlation, the dosage is negatively correlated with TH/TS ratio (P < 0.01). (3) Compared with E, the activity of IL-2 in group B and C decreased significantly (P < 0.01). By linear correlation, there is negative correlation between dosage and IL-2 activity (P < 0.01). There is no significant difference between D and F (P > 0.05). (4) There is positive correlation between TH/TS ratio and IL-2 activity in different dilutions (P<0.01). CONCLUSION: The mechanism of suppressive effect of SmBI on aCL induced by beta2-GP I may be realized by resuming the elevated TH/TS ratio and IL-2 activity. The state that SmBI have no effect on normal mice indicates that SmBI has selective immunoregulative functive.
