Background Selective laser trabeculoplasty(SLT)has been widely accepted for the treatment of open-angle glaucoma.However,there are few reports about its application in treating angle-closure glaucoma so far.Objective This study was to clinically evaluate the safety and efficacy of selective laser trabeculoplasty for primary angle-closure glaucoma with opened anterior angle follow-up surgery.Methods A case-observational design was adopted in this study.A total of 33 eyes from 23 angle-closure glaucomatous patients with opened 180° angle were enrolled.All the patients understood this trial and written informed consent was obtained prior to the medical treatment.The average preoperative intraocular pressure(IOP)and number of medication were(23.07±4.01)mmHg and 1.52±0.66,respectively.A frequency doubled Q-switched Nd:YAG laser was used to irradiate the trabecular meshwork with 70-80 laser spots over 180°.The same preoperative anti-glaucoma drugs were topically administered during the follow-up period.Visual acuity,IOP,slit lamp examination,gonioscopy and the coefficient of outflow facility were regularly assessed and performed after laser surgery.Results The IOP values of the 33 eyes were(18.78±4.87)mmHg,(18.83±3.95)mmHg,(19.78±4.48)mmHg,(19.63±3.68)mmHg,(19.11±3.36)mmHg,and(21.17±3.14)mmHg 1 day,l week,and 1,3,6,9 months after operation,showing significant decline in comparison with preoperation(P＜0.01).The mean drug uses were 1.63±0.85,1.23±1.01,1.25±0.98,1.21±1.02,1.22±0.86,and 1.69±0.53 at the same time point after operation,respectively,and significant differences were found 1 week,1,3,6 months in postoperation in comparison with preoperation(P =0.020,0.026,0.020,0.031).Ciliary congestion and aqueous flare naturally disappeared 1 week after surgery.The coefficients of outflow facility were 0.11±0.09 and 0.23±0.15,respectively at pretreatment and 3 months after SLT with a statistically significant difference (P=0.002).Conclusions Selective laser trabeculoplasty is effective and safe for angle-closure glaucoma.However,it is essential to have 1/2 circle of anterior chamber open for SLT in angle-closure glaucoma.

OBJECTIVETo explore the characteristics of closed abdominal injury in pregnancy women and its treatment.

METHODSThe clinical data of 37 pregnancy patients with closed abdominal injury treated in our hospital from June 1993 to June 2003 were collected and analyzed.

RESULTSAll the 37 patients were treated with operation. Among them 2 early pregnancy patients with intestinal rupture and 1 patient with retroperitoneal hematoma were treated under laparoscope; in other 34 pregnancy patients laparotomy was performed. Of the 34 patients 8 used cesarean section because premature separation of placenta and enlarged womb interrupted the management of intra-abdominal organ injury. In the 37 patients 33 (89.1%) were cured, 4 (10.8%) die, postoperative complication rate was 16.2% (6/37). Two patients (5.4%) suffered from abdominal cavity infection, 3 (8.1%) from pulmonary infection, and 1 (2.7%) had multi-organ failure.

CONCLUSIONSFor pregnancy patients with closed abdominal injury, besides obsteric diseases intra-abdominal injury should be given much attention. Accurate diagnosis and timely treatment can gain the time to save the life of both mother and fetus.

OBJECTIVETo investigate the changes of thyroxin and monocyte human leukocyte antigen-DR expression in senior patients with sepsis and explore their clinical significance.

METHODSAccording to the 2001 SCCM/ESICM/ACCP/ATS/SIS international sepsis definitions, 125 senior patients with sepsis free of thyroid conditions were divided into non-severe sepsis group (n=86) and severe sepsis group (n=39), with another 30 healthy subjects as the control. Thyroid function was assayed by chemoluminescence method in these patients and monocyte HLA-DR expression was determined by flow cytometry.

RESULTSCompared with the control group and non-severe sepsis cases, the levels of free T3 (FT3), free T4 (FT4), T3, T4 and monocyte HLA-DR expression were significantly lower in severe sepsis cases (P<0.05), but the levels of thyroid stimulating hormone (TSH) were comparable between the 3 groups (P>0.05). The non-severe sepsis cases showed significantly lower levels of FT3, FT4, T3, T4, TSH and monocyte HLA-DR expression than the control group (P<0.05). In severe sepsis group, the levels of FT3, FT4, T3, T4 and monocyte HLA-DR expression showed significant differences between the fatal cases and surviving cases (P<0.05).

CONCLUSIONThe levels of thyroxin and monocyte human leukocyte antigen-DR expression are obviously lower in senior patients with severe sepsis, and their detection may well indicate the severity of the condition and help make prognostic judgment.

To investigate genetic mechanisms of high altitude adaptations of native mammals on the Tibetan Plateau, we compared mitochondrial sequences of the endangered Pantholops hodgsonii with its lowland distant relatives Ovis aries and Capra hircus, as well as other mammals. The complete mitochondrial genome of P. hodgsonii (16,498 bp) revealed a similar gene order as of other mammals. Because of tandem duplications, the control region of P. hodgsonii mitochondrial genome is shorter than those of O. aries and C. hircus, but longer than those of Bos species. Phylogenetic analysis based on alignments of the entire cytochrome b genes suggested that P. hodgsonii is more closely related to O. aries and C. hircus, rather than to species of the Antilopinae subfamily. The estimated divergence time between P.hodgsonii and O. aries is about 2.25 million years ago. Further analysis on natural selection indicated that the COXI (cytochrome c oxidase subunit I) gene was under positive selection in P. hodgsonii and Bos grunniens. Considering the same climates and environments shared by these two mammalian species, we proposed that the mitochondrial COXI gene is probably relevant for these native mammals to adapt the high altitude environment unique to the Tibetan Plateau.

OBJECTIVETo evaluate the efficacy and safety of Flos Abelmoschus manihot (Malvaceae) on type 2 diabetic nephropathy (DN).

METHODSThe Cochrane Library, PubMed/MEDLINE, Excerpta Medical Database, Chinese electronic literature databases, and the references of relevant articles were searched in March 2012 for randomized controlled trials (RCTs) that reported the effects of Flos A. manihot on type 2 DN patients with overt but subnephrotic-range proteinuria (500-3,500 mg/24 h). The quality of trials was evaluated using the Cochrane-recommended method. The results were summarized as risk ratios (RRs) for dichotomous outcomes or mean differences (MDs) for continuous outcomes.

RESULTSSeven trials (531 patients) were included. Flos A. manihot significantly decreased proteinuria [MD -317.32 mg/24 h, 95% confidence interval (CI) [-470.48, -164.17],P<0.01]. After excluding a trial that only included patients with well-preserved renal function, Flos A. manihot was associated with a significant decrease in serum creatinine (MD -11.99 μmol/L, 95% CI [-16.95, -7.04],P<0.01). Serious adverse events were not observed. The most common adverse event was mild to moderate gastrointestinal discomfort; however, patients receiving this herb did not have an increased risk for tolerated gastrointestinal discomfort (RR 1.48, 95% CI [0.39, 5.68],P=0.57).

CONCLUSIONSFlos A. manihot may be considered as an important adjunctive therapy with the first-line and indispensable therapeutic strategies for type 2 DN. High-quality RCTs are urgently needed to confirm the effect of Flos A. manihot on definite endpoints such as end-stage renal disease.

OBJECTIVETo explore efficacy of imatinib for patients with chronic myeloid leukemia(CML) and its resistance-related factors during the treatment.

METHODSThe clinical data of 214 CML patients received imatinib were analyzed respectively in our hospital from April 2005 to December 2010. The therapy history and efficacy of regular follow-up and factors influencing drug resistance were analyzed. COX regression analysis was used to perform the univariate and multivariate analysis.

RESULTSUntil the end of follow up, thirty-one patients (14.5%) occurred drug resistance. One of them was in accelerated phase(AP), and two in blast phase(BP); 69.2% of patients achieved a complete cytogenetic response(CCyR), and 31.3% of patients achieved a major molecular response(MMR). COX analysis was performed in 207 chronic phase(CP) patients. Univariate analysis showed that the course of disease before treatment, the hemoglobin count, the white blood cell count, whether achieved CCyR or not and whether achieved MMR or not were the influencing factors for imatinib resistance. Multivariate analysis showed that whether achieved CCyR or not was the independent factor for drug resistance.

CONCLUSIONWhether achieved CCyR or not is an independent factor and also a protective factor for imatinib resistance in patients with CML.

Objective:The aim of this study was to research the relationship between HPLC fingerprint and anti-inflammatory effect of Zhideke granules， and the substance basis of its anti-inflammatory effect was preliminary explored. Method:The fingerprint of 10 batches of Zhideke granules were determined by HPLC， the mobile phase was consisted of methanol-0.2% phosphoric acid solution for gradient elution with a detection wavelength of 254 nm. Similarity analysis， hierarchical cluster analysis （HCA）， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were used to evaluate the quality difference between batches of Zhideke granules. The correlation analysis between the common peaks and the inhibition rates of Zhideke granules on ear swelling and cotton ball granuloma in mice was carried out by partial least squares （PLS）， and the peaks greatly contributing to the anti-inflammatory effect were screened out. Result:There were 31 common peaks in the HPLC fingerprint of Zhideke granules. The similarities of 10 batches samples were ≥0.992. The HCA and PCA analysis results were consistent， and the samples were divided into 3 categories. Combined with the OPLS-DA results， 15 components were the main markers affecting the differences of different batches of samples. Different batches of Zhideke granules differed in anti-inflammatory effect. The chromatographic peaks being positively correlated with the anti-inflammatory effect were mainly from Belamcandae Rhizoma and Scutellariae Radix， Chromatographic peaks 3， 6， 19， 27-30 had significant contribution to anti-inflammatory effect， of which peaks 28 and 30 were irisflorentin and wogonin. Conclusion:HPLC fingerprint combined with chemical pattern recognition method can provide a reference for systematic evaluation of the overall quality of Zhideke granules. Zhideke granules has a certain inhibitory effect on acute and chronic inflammation in mice， and the anti-inflammatory effect is the result of the combined action of various ingredients， while Belamcandae Rhizoma and Scutellariae Radix have significant significance for the anti-inflammatory effect.
