Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

BACKGROUND:Currently, there are large numbers of studies related to the association between colagen type I alpha1 (COL1A1) Sp1 polymorphism and bone mineral density and fracture risk, but the results are inconsistent. OBJECTIVE:To evaluate the impact of the COL1A1 Sp1 polymorphism on bone mineral density and fracture by using the Meta-analysis. METHODS:We comprehensively searched the eligible studies for the present meta-analysis through MEDLINE, PubMed, EMBASE databases. Pooled odds ratios and 95% confidence intervals of Sp1 polymorphisms for bone mineral density and fracture risk were obtained, with attention to study quality and publication bias. RESULTS AND CONCLUSION:A total of 32 studies met the inclusion criteria, among which, 22 studies evaluated the Sp1 polymorphism and fracture risk. Significant associations were found in five genetic models. In the stratified analysis by region, the same results were found in the Europeans but not Americans and Asians. Thirteen studies evaluated the Sp1 polymorphism and low bone mineral density risk. A similar result was obtained. However, the analysis of bone mineral density data showed an increased relation between Sp1 polymorphism and low bone mineral density in Europeans and Americans but not in Asians. Overal, the current meta-analysis concludes that the COL1A1 Sp1 polymorphism is associated with low bone mineral density and fracture risk, especialy in Europeans. However, susceptibility to them varies markedly among populations from different regions.

BACKGROUND:Several studies have attempted to apply mouse nerve growth factor to local lesions of peripheral nerve and found that local injection of mouse nerve growth factor can promote nerve recovery, which is superior to systematic application. OBJECTIVE:To evaluate the clinical effects of gelatin sponge infiltrated by mouse nerve growth factor in the repair of peripheral nerve injury. METHODS:Thirty-six patients with single peripheral nerve injury, including 16 males and 20 females, aged 18-48 years, were randomly divided into two groups: 18 patients in case group underwent debridement and neuroanastomosis, and then the injured nerve was wrapped by gelatin sponge which was infiltrated by mouse nerve growth factor and folowed by plaster fixation, anti-inflammatory therapy, neurotrophy and circulation improvement therapy; the other 18 patients in control group were treated only with debridement and neuroanastomosis and other conventional therapies. At 4 weeks after treatment, electrophysiological examination was performed. In addition, sensory and motor function of the distal end of injured nerve was evaluated at 6 months after treatment. RESULTS AND CONCLUSION: Sensory evoked potential and motor evoked potential showed that the recovery rate was 78% (n=14) and 83% (n=15) respectively in the case group, while 57% (n=10) and 66% (n=12) in the control group. There was significant difference between the two groups (P < 0.05). The total effective rate was 94.4% (n=17) in the case group and 83.3% (n=15) in the control group, which were statisticaly better in the case group than the control group (P < 0.05). These findings indicate that it is significantly effective to treat peripheral nerve injury by gelatin sponge infiltrated by mouse nerve growth factor that has good biocompatibility.

Objective To discuss the clinical value of Protein induced by Vitamin K Antagonist-Ⅱ (PIVKA-Ⅱ) and alpha-Fetoproteins (AFP) in diagnosing hepatocellular carcinoma (HCC) and monitoring the treatment effects.Methods Patients were recruited by the Affiliated Hospital of Qingdao University,from August 2013 to March 2014.Serum levels of PIVKA-Ⅱ and AFP were measured by both chemiluminescence assay (CLIA) and electrochemiluminescence assay (ECLA) in patients with HCC (n =148),intrahepatic cholangiocellular carcinoma (n =37),gastric cancer and colorectal cancer (n =44),cirrhosis (n =63),chronic hepatitis B (n =38) and healthy subjects (n =57).To analyze the areas under the receiver operating characteristic curves (ROC-AUC) and to compare the sensitivity and specificity of single PIVKA-Ⅱ or AFP assay,and the combined detection.To analyze the correlation of PIVKA-Ⅱ and both tumor size and TNM staging,so do AFP,respectively.To compare the serum level changes of the two indicators in HCC patients before and after treatment.Results The serum levels of both PIVKA-Ⅱ and AFP in HCC group were higher than that in intrahepatic cholangiocellular carcinoma,gastric cancer and colorectal cancer,cirrhosis,chronic hepatitis B and healthy subjects groups (PIVKA-Ⅱ:U =866.50,424.00,958.00,292.00 and 448.00 ; AFP:U=713.00,440.50,1 182.00,614.00 and 399.00,P ＜0.001).The ROC-AUCs of the single PIVKA-Ⅱ or AFP assay and the combined detection in HCC group were not statistically different (P ＞ 0.05).The sensitivity of PIVKA-Ⅱ (87.16％) was higher than that of AFP (68.92％,x2 =4.73,P ＜ 0.05) in diagnosing HCC ; the sensitivity of the combined detection of PIVKA-Ⅱ and AFP(93.24％) was higher than that of PIVKA-Ⅱ itself (87.16％,adjusted x2 =64.70,P ＜ 0.01) ;while the specificities among them did not show statistical significance (P ＞ 0.05).Tested by Spearman rank correlation,the serum levels of PIVKA-Ⅱ and AFP were both positively related to tumor size (r =0.716,0.475 respectively,P ＜ 0.001).The serum levels of PIVKA-Ⅱ and AFP in HCC patients increased gradually correlated with tumor size (H =72.70,37.02 respectively,P ＜ 0.001) and the positive rates of PIVKA-Ⅱ and AFP were gradually improved (x2 =26.74,21.62 respectively,P ＜ 0.01),too.Based on the International TNM Staging System,the serum levels of PIVKA-Ⅱ and AFP (H =46.63,21.38 respectively,P ＜0.001) and the positive rates of PIVKA-Ⅱ and AFP (PIVKA-Ⅱ:x2 =20.40,P ＜0.01 ;AFP:x2 =8.33,P ＜0.05) in HCC patients from Ⅰ-Ⅳ stages were increased as TNM stages elevated.The serum levels of PIVKA-Ⅱ and AFP in HCC patients were both dropped sharply compared with preoperative levels (Z =-4.59,-4.22 respectively,P ＜ 0.001) and also both dropped in each of the Ⅰ-Ⅳ TNM stages (PIVKA-Ⅱ:Z =-2.85、-2.98、-2.70 respectively,P ＜ 0.05 ; AFP:Z =-2.48、-3.82、-2.50 respectively,P ＜ 0.05) compared with serum levels before treatment.Conclusion PIVKA-Ⅱ and AFP both have high clinical application values in diagnosing HCC and monitoring treatment effects.The sensitivity of PIVKA-Ⅱ in diagnosing HCC is significantly higher than AFP,and the sensitivity can be elevated by the combined detection in diagnosing HCC without reducing the specificity.

Objective To investigate the effects of gabapentin on high-voltage-activated calcium currents in dorsal root ganglion (DRG) neurons in mice with oxaliplatin-induced neuropathic pain (NP). Methods Pathogen-free male Kunming mice aged 6 weeks weighing 20-25 g were used in this study. NP was induced by injection of intraperitoneal oxaliplatin 3 mg/kg. Successful induction of NP was defined as the mechanical paw withdrawal threshold (MWT) measured at 3 d after oxaliplatin administration decreased to 40% of the baseline ( before administration of oxaliplatin). Forty-one mice in which NP was successfully induced were randomly divided into 2 groups: NP group ( n = 20) and gabapentin group (group G, n = 21 ). Another 10 normal mice served as control group (group C). At 3 days after oxaliplatin administration, gabapentin 100 mg/kg was injected intraperitoneally once a day for 3 consecutive days in group G, while C and NP groups received the equal volume of normal saline.MWT to von Fray filament stimulation was measured immediately before and 1-3 days after gabapentin administration (T1-4). After the last measurement of MWT, bilateral L4.5 DRG was collected and neurons were isolated. The high-voltage-activated calcium currents were recorded using whole-cell patch-clamp technique. The peak current density and the voltage where half of the current was activated ( Va1/2 ) or inactivated ( Vi 1/2 ) were calculated. Results Compared with group C, MWT at T1-4 was decreased, the peak current density and Vi1/2 were significantly increased in group NP, and MWT at T1 was decreased in group G ( P ＜ 0.05). There was no significant difference in the peak current density, Vi1/2 and Va1/2 between C and G groups ( P ＞ 0.05). MWT at T2-4 was significantly increased, while the peak current density and Vi1/2 were significantly decreased in group G compared with group NP (P ＜ 0.05). Conclusion Gabapentin can reduce oxaliplatin-induced NP in mice through inhibiting high-voltage-activated calcium currents and promoting the inactivation of the channels in DRG neurons.
