INTRODUCTION A 56-year-old Chinese female patient with A （H1N1） influenza pneumonia accompanied by acute disseminated encephalomyelitis （ADEM） of the Central Nervous System （CNS） is described in this article. The patient had typical clinical manifestation, and the diagnosis was reached after MRI and other examinations. From this case, we can conclude that the virus of A （H1N1） influenza can infect CNS, and we should pay more attention to patients of A （H1N1） influenza pneumonia with neurological complications.

BACKGROUND This case-control study compared the short-term clinical efficacy of natural orifice specimen extraction surgery(NOSES) using a prolapsing technique and the conventional laparoscopic-assisted approach for low rectal *** To further explore the application value of the transanal placement of the anvil and to evaluate the short-term efficacy of NOSES for resecting specimens of low rectal cancer, as well as to provide a theoretical basis for its extensive clinical *** From June 2015 to June 2018, 108 consecutive laparoscopic-assisted low rectal cancer resections were performed at our center. Among them, 26 specimens were resected transanally using a prolapsing technique(NOSES), and 82 specimens were resected through a conventional abdominal wall small incision(LAP). A propensity score matching method was used to select 26 pairs of matched patients, and their perioperative data were *** The baseline data were comparable between the two matched groups. All 52 patients underwent the surgery successfully. The operative time, blood loss,number of harvested lymph nodes, postoperative complication rate,circumferential margin involvement, postoperative follow-up data, and postoperative anal function were not statistically significant. The NOSES group had shorter time to gastrointestinal function recovery(2.6 ± 1.0 d vs 3.4 ± 0.9 d, P= 0.006), shorter postoperative hospital stay(7.1 ± 1.7 d vs 8.3 ± 1.1 d, P = 0.003),lower pain score(day 1: 2.7 ± 1.8 vs 4.6 ± 1.9, day 3: 2.0 ± 1.1 vs 4.1 ± 1.2, day 5: 1.7± 0.9 vs 3.3 ± 1.0, P < 0.001), a lower rate of additional analgesic use(11.5% vs61.5%, P = 0.001), and a higher satisfaction rate in terms of the aesthetic appearance of the abdominal wall after surgery(100% vs 23.1%, P < 0.001).CONCLUSION NOSES for low rectal cancer can achieve satisfactory short-term efficacy and has advantages in reducing postoperative pain, shortening the length of postoperative hospital stay, and improving pat

AIM: To study the criterion-reference of endotamponades in pars plana vitrectomy for metallic intraocular foreign body (MIOFD) associated with endophthalmitis. METHODS:Thirty-six patients of MIOFD with endophthalmitis accorded with Exclusion and inclusion criteria were retrospectively analyzed. A detailed analysis of the patients' natural factors, preoperative examinations, intraoperative endotamponades choice, postoperative complications and therapeutic effects was performed. RESULTS: BSS was used in 4 eyes without obvious retinal damage. There was no postoperative complication and their visual acuity (VA) was improved. Sixteen eyes that had mild retinal damage filled with C3F8 gas. The postoperative VA improved in 10 eyes (62.5%), 4 eyes (25.0%) remained unchanged and 2 eyes (12.5%) decreased. Only 2 cases occurred postoperative retinal detachment in gas group. Another 16 eyes with serious retinal damage were treated with silicone oil. Postoperative VA of 9 eyes (56.3%) improved, 3 eyes (18.8%) remained unchanged and 4 eyes (25.0%) decreased. The silicone oil group had higher incidence of postoperative complications, but the incidence of secondary treatment had no significant different between silicone oil and gas group. CONCLUSION: An appropriate choice of endotamponades in vitrectomy surgery for MIOFB with endophthalmitis is important for prognosis.

Three new Keggin polyoxometalates, [Zn（phen）3]2[SiW12O40]＇5H2O（1）, [Co（phen）3]2[SiW12O40]（2） and [Ni（phen）3]2[SiW12O40].2H2O（3）（phen=1,10＇-phenanthroline） have been hydrothermally synthesized and characterized by elemental analysis, IR, crystal X-ray diffraction, thermogravimetric analyses（TGA） and fluorescence tech- niques. Complex 1, crystallized in the triclinic space group Pi, consists of one [SiW12O40]4 anion, two discrete [Zn（phen）3]^2＋ cations and five crystal water molecules. Complexes 2 and 3 have the similar configuration to complex 1, but they crystallized in the monoclinic space group C2/c. Variable-temperature magnetic susceptibilities of complexess 2 and 3 reveal antiferromagnetism and ferromagnetism, respectively.
