Objective To investigate the influence of nasal continuous positive airway pressure (nCPAP) treatment on cardiovascular risk factors in patients with obstructive sleep apnea-hypopnea Syndrome (OSAHS). Methods Thirty-one patients with newly diagnosed OSAHS were divided into 3 groups based on the status of nC-PAP treatment: group 1,10 patients with nCPAP > 4 hrs/night;group 2:9 patients with nCPAP < 4 hrs/night;group 3:12 patients without nCPAP treatment. Serum cardiovascular risk factors (i. e. ,C-reactive protein(CRP), total cholesterol, triglycerides, highdensity lipaprntein cholesterol (HDL-C), low-density lipoprotein cholesterol, apo-lipoprotein A-I (ApoA-1), and apolipoprotein B (ApoB) ) were measured at baseline and 6 months after nCPAP treatment. Results ① There was no significant difference on age,body mass index,blcod pressure,Epworth sleepi-ness scale (ESS) and saturation of blood oxygen (SPO_2) between the 3 groups (P>0.05). ②In group 1, ESS, SPO_2 minimum SPO_2 were significantly improved (3.20±2.80,93.80±2.01 and 84.10±6.17, respectively) compared to baseline (13.30±5.20,88.60±4.14 and 69.60±11.80, respectively) (P<0.01). Moreover, in group 2, there were significant improvement on ESS, SPO_2 and minimum SPO2 (4.95±2.67,94.20±1.46 and 85.20±4.97, respectively) compared to baseline (12.80±5.50,89.10±5.11 and 73.70±12.50, respectively) (P<0.01). ③In group 1 ,significant decreases in the levels of CRP,total cholesterol was observed (P=0.021 and 0.038). ④In group 2, group 3 there were slightly decrease of CRP after treatment, but the difference did not reach statistieal significance. Conclusions Good compliance to nCPAP treatment decreases the serum levels of cardiovas-cular risk factors, indicating a beneficial effect on the overall cardiovascular disease prevention and control.

A total of 185 hospitalized patients with chronic obstructive pulmonary disease (COPD) were recruited.And the questionnaire of COPD Assessment Test (CAT) was used to evaluate the CAT scores and Hamihon Depression Scale to evaluate HAMD scores.Lung function,body mass index,smoking and medication were measured and recorded in details.According to the HAMD scores,65 cases had depression and 120 cases no depression.Comparing with the no-depression group,the results show that HAMD and CAT scores were higher significantly in the depression group and there was a lower proportion of long-term domiciliary oxygen therapy.According to the logistic regression analysis,the CAT scores were associated with global initiative for chronic obstructive lung disease (GOLD) stages Ⅳ and HAMD scores.These results suggest that poor lung function and depression affect greatly the quality of life for stable COPD patients.

Dry eye is now one of the most common superficial disorders in ophthalmology at home and abroad, and more and more people attach importance to the study. The ideal approach for treatment of dry eye is to normalize the condition by rebuilding the superficial circumstance of the eye, and to make tear film work as well as possible so as to relieve the irritating symptoms in the eye. The authors are making a comprehensive discussion on the methods and curative effects of treating dry eye by traditional Chinese medicine and by integrative Chinese and Western medicine in recent years, so as to introduce the distinctive features of the traditional Chinese medicine and integrative Chinese and Western medicine in this field.

OBJECTIVETo objectively evaluate the therapeutic effect and safety of Runmushu Oral Liquid (RMS) for the treatment of xerophthalmia in postmenopausal women.

METHODSSeventy-two postmenopausal women (144 eyes) with xerophthalmia of aqueous tear deficiency type were assigned to two groups. Patients in the treated group were treated with RMS (consisted of prepared and crude rehmannia root, figwort, lilyturf root, dendrobium stem, wolfberry fruit, chrysanthemum and sticktight) orally combining with local applying of Hialid eye drops; while those in the control group were treated with Hialid eye drops alone. Changes of subjective symptoms and objective indices in the two groups were observed and compared before and after 1-month treatment.

RESULTSAfter 1 month of treatment, the total effective rate was 86.1% (62/72) in the treated group and 66.7% (48/72) in the control group, showing significant difference between them (P < 0.01). Significant differences between groups were also shown in improvements of total scores of subjective symptoms (P < 0.01), scores of tear film break-up time (BUT) and Schirmer I test, these indices in the treated group were better (P < 0.01). However, the improvement of cornea fluorescin staining scores was insignificant different between groups (P > 0.05).

CONCLUSIONRMS with artificial-tears can alleviate the eye symptoms, prolong the BUT, promote the secretion of tears in treating postmenopausal women xerophthalmia, showing a therapeutic effect superior to that by artificial-tears alone.

OBJECTIVETo investigate the epidemiological features of the pathogens responsible for prostatitis in the Changshu area, and offer some evidence for the clinical treatment of prostatitis.

METHODSThis study included 2 306 cases of prostatitis that were all clinically confirmed and subjected to pathogenic examinations in 3 hospitals of Changshu area from 2008 to 2012. Neisseria gonorrhoeae, mycoplasma urealyticum and chlamydia trachomatis were detected by nucleic acid amplification ABI 7500, the bacterial data analyzed by VITEK-2 Compact, the drug-resistance to antibacterial agents determined using the WHONET 5.6 software, and the enumeration data processed by chi-square test and curvilinear regression analysis using SPSS 19.0.

RESULTSThe main pathogens responsible for prostatitis were found to be Staphylococcus haemolyticus (30%), Staphylococcus epidermidis (12%), Enterococcus faecalis (9%), Escherichia coli (6%), Staphylococcus warneri and Staphylococcus aureus (3%), Mycoplasma urealyticum (8%), chlamydia trachomatis (5%) and Neisseria gonorrhoeae (6%). Statistically significant increases were observed in the detection rates of Escherichia coli (chi2 = 17.56, P<0.05), Mycoplasma urealyticum (chi2 = 8.73, P<0.05), Chlamydia trachomatis (chi2 = 8.73, P<0.05) and Enterococcus (chi2 = 8.22, P<0.05), but not in other pathogens. The resistance rates of Gram-positive bacteria to erythromycin and benzylpenicillin G were both above 45%, but with no significant difference between the two, those of Oxacillin (chi2 = 10.06, P<0.05) and Cefoxitin (chi2 = 9.89, P<0.05) were markedly increased, but those of quinolones, gentamycin and clindamycin remained low, except rifampicin (chi2 = 11.09, P<0.05). The resistance rates of Gram-negative bacteria to cefazolin and ampicillin were relatively high (mean 57.3%), and those to ceftriaxone (chi2 = 11.26, P<0.05) and trimethoprim sulfamethoxazole (chi2 =11.00, P< 0.05) significantly high; those to amikacin, cefepime, piperacillin/tazobactam and imipenem remained at low levels with no significant changes. However, the resistance rates of mycoplasma urealyticum to ciprofloxacin (chi2 = 11.18, P<0.05) and azithromycin (chi2 = 9.89, P<0.05) were remarkably increased.

CONCLUSIONGram-positive bacteria are the major pathogens responsible for prostatitis, but Escherichia coli, enterococcus and sexually transmitted disease pathogens are found to be involved in recent years. Quinolones and aminoglycosides are generally accepted as the main agents for the treatment of Gram-positive bacterial infection. However, rational medication for prostatitis should be based on the results of pathogen isolation and drug sensitivity tests in a specific area.

OBJECTIVEIn order to develop the diagnostic genechip for specific detection of Schistosoma japonicum (Chinese mainland strain).

METHODSProbe and primers were designed based on the Schistosoma japonicum 5D gene encoding an immunogenic miracidial antigen. The probe for the conservative and specific gene sequence was spotted onto the specially treated glass slides by pin-based spotting robot Pixsys 5500 and was employed to make genechips. A polymerase chain reaction (PCR) protocol was designed to effectively amplify the 5D gene fragment containing the probe sequence from cercaria, egg, adult worm and infected Oncomelania DNA as well as other flukes DNA, respectively. After 35 cycles by PCR, the products were then labeled with fluorescent Cy3-labeled primer, using dissymmetrical PCR. The labeled PCR products of the target genes were hybridized to the diagnostic genechips for detection of Schistosoma japonicum and a fluorescent scanner (ScanArray 3000) was used to observe and record the hybridization signals.

RESULTSThe result obtained from the study showed that a 262 bp DNA fragment was amplified from cercaria, egg and adult worm with the designed primers and enable the genechip be applied to detect a single cercaria, egg and adult worm. When the genechip was used to detect Clonorchis sinensis, Fasciolopsis busk, and Paragonimus westermani DNA, the results showed negative, indicating that the genechip had good specificity.

CONCLUSIONThe genchip technique for detection of Schistosoma japonicum was established successfully and having the characteristics of high sensitivity and specificity.

The aim of the present study is to investigate the effects of Panax notoginseng saponins (PNS) on pneumocyte apoptosis and apoptosis-related protein, as well as c-Jun N-terminal kinase (JNK) in lung ischemia/reperfusion (I/R) injury. Thirty Wistar rats were randomly divided into control group, I/R group and PNS group. The unilateral lung I/R model was replicated by obstruction of left lung hilus for 30 min and reperfusion for 120 min in vivo. The rats in PNS group were given intraperitoneal injection of PNS at 60 min before ischemia and 10 min before reperfusion. Some lung tissues sampled at the end of the experiment were assayed for wet/dry weight ratio (W/T). The expressions of phosphorylated JNK (p-JNK) and JNK protein were detected by Western blot. The expressions of Bcl-2, Bax and Caspase-3 protein were detected by immunocytochemistry techniques. The pneumocyte apoptotic index (AI) was detected by terminal deoxynuleotidy1 transferase mediated dUTP nick end labeling (TUNEL). The morphological and ultrastructure changes were observed under light microscope and electron microscope, and the injured alveolus rate (IAR) was counted as well. The results showed that compared to control group, I/R group showed increased expressions of p-JNK, Bcl-2, Bax and Caspase-3 protein (all P < 0.01), decreased ratio of Bcl-2/Bax (P < 0.05), and increased values of AI, W/T and IAR (all P < 0.01). Moreover, light microscope and electron microscope showed serious morphological and ultrastructure injury in I/R group. Compared to I/R group, PNS group showed markedly decreased expressions of p-JNK, Bax and Caspase-3 protein (all P < 0.01), increased expression of Bcl-2 protein and ratio of Bcl-2/Bax (both P < 0.01), and lower values of AI, W/T and IAR (all P < 0.01). Meanwhile, light morphological and ultrastructure injury was found to be alleviated in PNS group. These results suggest that PNS can protect lung tissue from I/R injury, and the mechanism may correlate with suppressing JNK signal pathway, up-regulating the ratio of Bcl-2/Bax which results in inhibition of Caspase-3 dependent apoptosis.

OBJECTIVETo investigate the protective effects and mechanism of SP600125-specificity inhibitor of c-Jun N-terminal kinase (JNK)on lung ischemia /reperfusion injury in rats.

METHODSThe unilateral lung ischemia/reperfusion model was replicated in vivo. Rats were randomly divided into three groups (n = 10): control group, ischemia/reperfusion group ( I/R group) and ischemia/reperfusion + SP600125 group (SP600125 group). The lung tissues sampled at the end of each experiment were assayed for wet/dry weight ratio (W/D),the injured alveoli rate (IAR), the expression of phosphorylation JNK (p-JNK) and JNK protein were detected by Western blot, the expression of Bcl-2, Bax, Caspase3 protein were detected by immunocytochemistry techniques, the pneumocyte apoptosis index (AI) was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end abeling(TUNEL), the ultrastructure changes were observed under electron microscope.

RESULTSCompared to I/R group, the expression of p-JNK, Bcl-2, Bax and caspase-3 protein were markedly decreased (all P < 0.01), the expression of Bcl-2 protein and the ratio of Bcl-2/Bax were markedly increased in SP600125 group(all P < 0.01). The value of AI, W/D, IAR showed significantly lower than those in I/R group (all P <0.01). Meanwhile, light morphological and ultrastructure injury were found in SP600125 group.

CONCLUSIONSP600125 can suppress JNK signal pathway, up-regulate the ratio of Bcl-2/Bax to inhibit Caspase-3 dependent apoptosis, so that it protects lung tissue from ischemia/reperfusion injury.
