Objective To seak a available way of evaluating morphology of filtering blebs after trabeculectomy is very important for forecasting the successful rate of surgery.At the present time,filtering blebs were commonly evaluated by using the slim lamp microscope,but it did not to exactly reflect the filtering passage.This study aimed to evaluate the morphology of filtering blebs after trabeculectomy with anterior segment optical coherence tomography (AS-OCT).MethodsThis was a prospective study.Sixty-nine eyes of 53 patients who had previously undergone trabeculectomy were selected in this study,including 25 eyes with open-angle glaucoma,38 eyes with close-angle glaucoma and 6 eyes with secondary glaucoma.These filtering blebs were classified into functional type (typeⅠandⅡ) and nonfunction type (type Ⅲ and Ⅳ) under the slit lamp microscope based on the van Buskirk grading scales.Intra-bleb morphology and structure were characterized as diffuse-like,cystic-like,encapsulating-like and flatten-like by AS-OCT in reference to the Leung method.The consistency between the two methods was evaluated by the Chi-Square test.Written informed consent was obtained from all the patients before surgery.ResultsThe average follow-up time was 10.78±11.0 months.All the patients finished the examination during the follow-up duration.The average intraocular pressure was(14.9±4.5)mmHg during the observation period.There were 38/69 (55.1%) functioning blebs and 31/69 (44.9%) non-function blebs under the slim lamp microscope.AS-OCT imaging showed diffuse-like blebs in 26 eyes (15.9%),cystic-like blebs in 11 eyes (27.5%),encapsulating-like blebs in 19 eyes (18.8%) and flatten-like in 13 eyes with the intraocular pressure of(13.16±3.77)mmHg,(15.36±2.92)mmHg,(15.77±5.07)mmHg and (16.62±5.33)mmHg,respectively,showing a significant difference among them (F=3.32,P＜0.05).These patterns of different OCT presented a good consistency with the clinical outcome (χ~2=0.03,P=0.86).ConclusionAS-OCT allows the observation of filtering blebs after glaucoma surgery.It is probably to visualize the internal structure of filtering bleb and deep sclerectomy.Functional and dysfunctional filtering blebs delivery gives different OCT patterns.This could be a new way to assess the postoperative healing process.

Objective To observe effect of abdomen compression on improvement of anal exsufflation for patients after abdomen operation. Methods Patients in the department of general surgery( 120 cases )after abdomen operations were randomly divided into the experimental group and the control group with 60 cases in each group.The control group adopted routine postoperative nursing,The experimental group received abdomen compression baaed upon routine nursing. Anal exsufflation time was compared between the two groups. Sults Anal exsufflation time of the experimental group undergoing different operations was earlier than that of the control group(P < 0.01 ). Conclusions Abdomen compression can bring forward anal exsufflation time,fa-cilitate the recovery of gastrointestinal function and normal diet, thus improve the rehabilitation of patients

BACKGROUND:Spine infection models are rarely reported in the literature. There are fewer reports on the imaging and histological observations of the animal model of spinal infection.
OBJECTIVE:To develop a canine model of pyogenic spinal infection.
METHODS:Twelve Chinese dogs were adopted in the study. The dogs were in the right arm recumbent. The surgery was conducted by retroperitoneal approach to expose T12/L1 intervertebral space. The intervertebral discs that exposed the intervertebral space were partial y removed, and the end plate of the adjacent two vertebrae was deliberately curetted out. Suspension with different concentrations of Staphylococcus aureus and sodium morrhuate were injected into the dog intervertebral space. The aim of removal of partial intervertebral discs and destruction of endplate was to make the vertebral body bone better in contact with the bacteria. The same operation was conducted in L5/6 clearance of the animal spine. At 14 days after surgery, animals were sacrificed. The infected intervertebral disc and adjacent vertebral bodies were taken out. Bacterial contents of specimens were quantitatively determined. During sacrificing, partial liver tissues and blood samples were col ected for bacterial culture. The occurrence of systemic infection was observed.
RESULTS AND CONCLUSION:(1) Spondylodiscitis of the lumbar spinal column was consistently produced in 90%(9/10) the sites chal enged with 102 colony-forming units (CFU) Staphylococcus aureus. Liver biopsy and blood culture did not show any signs of systematic infections. (2) Two out of four animals implanted the suspension with a concentration higher than 103 CFUs died within 3 days post-implantation. (3) These results suggested that a new canine model of pyogenic spinal infection was developed. This model could be used to test the efficacy of different anti-infection strategies.

Objective To investigate the potential association of Ghrelin(GHRL)gene polymorphisms susceptible to schizophrenia by case-control study.Methods Six hundred and thirty-four patients,six hundred and six healthy control subjects were recruited.Four SNPs rs696217,rs26802,rs27647 and rs26311 were detected by the polymerase chain reaction-based-restriction fragment length polymorphism analysis.Results No significant differences in genotype or allele frequencies of the four SNPs were observed between schizophrenic patients and healthy controls (Pvalues of genotype frequencies were 0.649,0.944,0.410,0.826;P values of allele frequencies were 0.773,0.992,0.301,0.723).However,seven haplotypes(GAAG,GAGC,GAGG,GCGC,GCGG,TAGC,TAGG)showed significant differences in frequency between schizophrenic and control groups(P values were 0.011,0.001,1.76×10-6,9.84×10-10,1.38×10-9,2.12×10-5,2.57×10-6).Conclusion These data suggest that the GHRL gene may not be associated with susceptibility to schizophrenia in the Chinese Han population.However,the haplotype of GA may be the susceptive factor of schizophrenia.

Objective To construct profiles of health status based upon physical,mental and social support items in adult twins of Qingdao.Methods Grade of Membership(GoM) model was applied to a set of 31 indicators to construct ideal profiles.Results Four health profiles were identified: pure type Ⅰ(healthy),pure type Ⅱ(personality disorders),pure type Ⅲ(psychological symptoms) and pure type Ⅳ(physiological symptoms).The most frequently occurring combination in this population was profile Ⅰ,Ⅱ,Ⅳ(14.74%),followed by profile Ⅰ,Ⅱ,Ⅲ,Ⅳ(13.44%),and then type Ⅰ(11.08%).Only 13.56% of subjects fell completely into one single pure type.Conclusions One healthy type and three non-healthy types are determined.Most individuals exhibit some of the characteristics of two or more types,holding partial membership in multiple categories.

Spillage of cyst contents during surgical operation is the major cause of recurrence after hydatid cyst surgery. Instillation of a scolicidal agent into a hepatic hydatid cyst is the most commonly employed measure to prevent this complication. SB202190 is a pyridinyl imidazole derivative and is known to be a specific inhibitor of p38 MAPK. In the present study, the scolicidal effect of SB202190 was investigated. Freshly isolated Echinococcus granulosus protoscolices were subjected to SB202190 treatment (10, 20, 40, and 80 microM), and the effects on parasite viability were monitored by trypan blue staining. Corresponding effects were visualized by scanning and transmission electron microscopy. Dose-dependent protoscolex death within a few days of SB202190 treatment was observed. Although the in vitro scolicidal effect of SB202190 was satisfactory, the in vivo efficacy of this drug and also possible side effects remain to be further investigated.

Objective Observation of the effects of Xinmailong injection on NGAL, hs-cTnT and RAAS in elderly patients with type 2 cardio-renal syndrome (CRS) , and EvaluatIon of the clinical efficacy and safety.Methods A total of 86 elderly patients who were collected from November 2015 to February 2017 were diagnosed as type 2 CRS in our department of geriatrics. According to the random number table method, they were randomly divided into two groups. Control group (43 cases) were treated with conventional medical therapy and xinmailong group (43 cases) were treated with xinmailong injection with a dose of 5 mg/kg twice a day for 15 days. The value of sneutrophil gelatin-associated apolipoprotein (NGAL) , hypersensitive troponin T (hs-cTnT) , brain natriuretic peptide (BNP) , plasma renin activity (PRA) , and angiotensin Ⅱ (Ang Ⅱ) , aldosterone (ALD) , left ventricular ejection fraction (LVEF) , six-minute walking test and other indicators were measured before and after treatment. Results After treatment, the value of NGAL, hs-cTnT, BNP, PRA, AngⅡ and ALD decreased in both groups, the value of LVEF and six-minute walking distance increased compared with those before treatment (P <0.05); The above indicators in the xinmailong group experienced a more significant alteration than in control group in the same period (P < 0.05); no side effect occurred in both two groups during the experiment. Conclusion Xinmailong injection can reduce the levels of NGAL, hs-cTnT and BNP in elderly patients with type 2 cardio-renal syndrome, improve heart and kidney function, and have curative positive effect and good safety. This study underlined the mechanism of Xinmailong injection may be related to the inhibition of RAAS activity.

OBJECTIVE: The medicinal mushroom Sanghuangporus vaninii produces pharmaceutically valuable hispidin polyphenols in natural habitats. However, due to the slow growth in nature, S. vaninii grown in the field (sclerotia) is not reliable for pharmaceutical purposes. Although higher biomass of fungal mycelia can be obtained in submerged cultures, the accumulation of hispidin polyphenols is rare. METHODS: In this study, the polyunsaturated fatty acids (PUFAs), linoleic acid (LA), linolenic acid (ALA), and methyl jasmonate (MeJa) were employed as the stimulant agents to coordinate the accumulation of biomass and hispidin polyphenols in its submerged cultures. RESULTS: The addition of LA and ALA promoted the mycelial accumulation, while the addition of MeJa inhibited the growth of S. vaninii concomitant with reduced total polyphenols. UPLC-Triple-TOF-MS analysis revealed an increased production of hispidin, phellinstatin, pinnilidine, and its derivatives upon the addition of LA and ALA, and hypholomine B and its isomer, 3,14'-bihispidinyl, and phelligridin E upon the addition of MeJa on day 13. Intriguingly, total polyphenols from the MeJa-supplementing cultures harbored a high capacity in scavenging free radicals. Chemical structural analysis showed that hispidin polyphenols had higher antioxidant activity due to more hispidin moieties induced by MeJa. CONCLUSION The supplement of PUFAs affects the synthesis and composition of hispidin polyphenols in S. vaninii. Our results provide a possibility to coordinate the production of hispidin polyphenols via submerged cultures of S. vaninii.

OBJECTIVETo investigate the correlation of apolipoprotein AI (ApoAI), ApoB, ApoB/ApoAI and the severity of brain white matter lesions (WML).

METHODSA total of 648 patients with WML confirmed by brain magnetic resonance imaging (MRI) were divided into mild WML group (=386) and moderate to severe WML group (=262) according to evaluations with the Fazekas scale. The demographic data, blood biochemical parameters and the levels of ApoAI, ApoB and ApoB/AI ratio were compared between the two groups to identify the risk factors of moderate to severe WML.

RESULTSUnivariate analysis showed that age, gender, hypertension, diabetes, coronary heart disease, previous stroke, homocysteine, HDL-C, ApoAI, and ApoB/AI ratio all differed significantly between the two groups ( < 0.05), but ApoB levels were similar between them ( > 0.05). Multivariate logistic regression analysis revealed that with ApoAI and ApoB/AI ratio as the continuous variables, after adjustment for the compounding factors, ApoB/AI ratio was an independent risk factor (OR=11.456, 95% : 3.622-36.229, < 0.001) and ApoAI was an independent protective factor for moderate to severe WML (OR=0.068, 95% : 0.018-0.262, < 0.001). With the upper quartiles of ApoAI level (1.38 g/L) and ApoB/AI ratio (0.58) as their respective cutoff values, patients with a high ApoAI level and a low ApoB/AI ratio were found to have the lowest incidence of moderate to severe WML ( < 0.001).

CONCLUSIONSAn increased ApoB/AI ratio is an independent risk factor and an increased ApoAI level is an independent protective factor for moderate to severe WML.
