Objective To explore the diangostic value of serumhigh sensitive C-reaction prtein (hsCRP) serum amyloid a (SAA) and C-reaction protein (CRP) in patients who had HBV hepatopathy.Method 127 subjects with hepatopathy caused by HBV infection and 50 control subjects were incorporated in this research,and 47 cases with HBV hepatitis,35 cases with HBV cirrhosis and 45 cases with hepatic failure and SAA and CRP hsCRP of every sample was detected.Results ①Levels of CRP and hsCRP in cases were significantly higher than controls (Mann-Whitney U test,Z=-2.792,-8.458,P＜0.01).②The hsCRP levels in the three different groups of cases were different (Kruskal-Wallis test,x2=11.625,P＜ 0.01).③The hsCRP level of group 2 and 3 was significantly higher than group 1 in the hepatic damage groups (Mann-Whitney U test,Z=-2.849,-2.902,P＜0.01).④But the level of SAA had no statistically significant in any group.⑤The seropositivity of hsCRP in cases group was 76.29 ％ and it was higher than CRP (11.34 ％) and SAA(26.80 ％).Conclusion The diangosic value of CRP and hsCRP may better than SAA in the patients who got HBV hepatic damage which maybe caused by detection method as hsCRP is better than CRP.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).

METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.

RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.

CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

OBJECTIVETo study the impact of left varicocele (VC) and varicocelectomy (VCT) on the apoptosis of spermatogenic cells and the levels of nitrogen monoxidum (NO) and interleukin 1 (IL-1) in the rat testis.

METHODSWe randomly divided 60 adolescent male SD rats into four groups of equal number: sham operation control, VC model 1 (VC1), VC model 2 (VC2), and VCT. We determined the semen quality and levels of NO and IL-1 in the testis tissue, detected the apoptosis of spermatogenic cells by TUNEL, and compared the indexes obtained among different groups.

RESULTSAn experimental VC model was successfully established by partially ligating the left renal vein of the rats. Sperm concentration and motility were significantly decreased in the VC1 ([1.54 ± 1.16] x 10⁶/ml and [44.23 ± 15.46]%) as compared with those in the sham operation group ([2.80 ± 1.62] x 10⁶/ml and [72.34 ± 12.62]%) (P < 0.05), but remarkably higher in the VCT ([1.82 ± 1.34] x 10⁶/mI and [51.21 ± 12.62]%) than in the VC2 group ([1.04 ± 1.21] x 10⁶/ml and [39.23 ± 13.21]%) (P < 0.05). The levels of NO and IL-1 in the left testes were markedly elevated in the VC1 ([0.172 ± 0.030] ng/ml and [1.468 ± 0.080 ] mg/ml) in comparison with those in the sham operation group ([0.134 ± 0.021] ng/ml and [0.782 ± 0.079 ] mg/ml) (P < 0.05), and significantly higher in the VC2 ([0.198 ± 0.020] ng/ml and [1.994 ± 0.090] mg/ml) than in the VCT group ([0.141 ± 0.010] ng/ml and [0.781 ± 0.036] mg/ml) (P < 0.05). However, the NO and IL-1 levels in the right testis showed no statistically significant differences between the two groups, and the two levels were positively correlated (r = 0.492, P < 0.01). The rats of the VC1 group exhibited remarkable apoptosis of spermatogenic cells in the bilateral testes, with significant differences in the apoptosis index ( AL) between the two sides (P < 0.05) as well as in the same side in comparison with the sham operation group (P < 0.01). The Als of spermatogenic cells in the bilateral testes showed statistically significant differences in the VCT (P < 0.05) but not in the VC2 group (P > 0.05), and those in the same side manifested dramatic differences between the VCT and VC2 groups (P < 0.01).

CONCLUSIONVaricocele induces changes of the NO and IL-1 levels in the testis tissue and increases the apoptosis of spermatogenic cells, which might be one of the causes of testis damage and spermatogenic dysfunction.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.

METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.

RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).

CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.

AIM:To observe the application efficiency of 5g/L indocyanine green ( ICG ) staining technique for continuous circular capsulorhexis ( CCC ) during phacoemulsification in white cataract.
METHODS:Ninety-eight patients (98 eyes) with white cataract were randomly divided into staining group ( 50 cases, 50 eyes) and control group (48 cases, 48 eyes). The control group didn't do anterior capsule staining. The staining group was injected to fill the anterior chamber, 5g/L ICG 0.1mL was applied on the central surface of the anterior capsule, using a 27G blunt needle through the side-port after 30s, and the redundant ICG was replaced by BSS, and continuous curvilinear capsulorhexis was accomplished using capsulorhexis forceps.
RESULTS: In staining group: after ICG staining, the capsule, which presented uniform light green and visualization of the anterior capsule was significantly improved. There are 48 eyes capsulorhexis success. The rate of success was 96%. Meanwhile, in control group, there was 29 eyes capsulorhexis success. The rate of success was 60%. The difference was statistically significant (P<0. 05). During follow-up, no dye particle and the complications of iritis or high intraocular pressure were found in the eyes of staining group. Anterior chamber inflammation, corneal opacity compared with control group, the difference was not statistically significant.
CONCLUSION:Indocyanine green staining increases the visibility of anterior capsule in over mature cataract, and it should be an effective and helpful method which can increase the success rate of capsulorehxis. At the same time, it can reduce the incidence of intraoperative complications. This will help beginners quickly grasp continuous curvilinear capsulorhexis, and shorten the learning curve.

Objective To evaluate the protective effect of Yersinia pestis capsular antigen F1 and recombinant rV270 on mice after immunization with them.Methods According to body weight,40 female Balb/c mice aged 6 to 8 weeks were randomly divided into four experimental groups(Fl-10 μg + aluminum adjuvant,F1-20 μg + aluminum adjuvant,rV-10 μg + aluminum adjuvant,and rV-20 μg + aluminum adjuvant) and a control group,8 in each group.Mice in experimental groups were immunized with the natural antigen F1 and recombinant antigen rV270 adsorbed to 25％ aluminum adjuvant and the control group was immunized with the same amount of aluminum adjuvant.Each mouse was immunized at the hind leg muscle with 100 ml immunizing agent,then a booster immunization was done once on the 21st day after the first immunization.The blood of all mice was collected on the 8th week after the first immunization,serum antibody titers were detected by ELISA and the data of antibody titers were analyzed by t test for comparison between groups.At the same time the mice were injected subcutaneously with 2000-fold LD50 of Yersinia pestis virulent strain 141,after 14 days,the protective effect of immunization was analyzed.Results The control group did not produce antibody.Antibody geometric mean titers (GMT) of the F1-10 mg + aluminum adjuvant and F1-20 mg + aluminum adjuvant groups were 1 ∶ 30443.9,and 1 ∶21527.8,respectively,and compared between the two groups,the difference was not statistically significant (t =1.1282,P ＞ 0.05).The GMTs of the rV-10 μg + aluminum adjuvant and rV-20 μg + aluminum adjuvant groups were 1 ∶ 13957.3 and 1 ∶18100.9,respectively,and compared between the two groups,the difference was not statistically significant(t =0.9408,P ＞ 0.05 ).After subcutaneous injection with Yersinia pestis virulent strain 141,all mice died in the control group but all survived in the experimental group.Conclusion The immune activity of natural antigen F1 and recombinant rV270 is high,which can be used as the main component of subunit vaccine in the plague subunit vaccine study.

?AlM: To compare the clinical effect between small-incision cataract surgery and phacoemulsification.
?METHODS: Totally 93 patients ( 124 eyes ) with age-related cataract who received treatment in Mar 2010 and Feb 2013 were dicided into 2 groups randomly. Forty-two patients ( 59 eyes ) in group small - incision cataract surgery ( SlCS ) were treated by SlCS, while other 51 patients ( 65 eyes ) in group Phaco were treated by phacoemulsification. And then, postoperative visual acuity, corneal astigmatism, surgically induced astigmatism ( SlA ) and intraoperative and postoperative complications were contrasted between groups.
?RESULTS: After 1d and 1wk of postoperation, there were 38 eyes ( 64. 4%) and 41 eyes ( 69. 5%) having a better visual acuity of 0. 5 in the SlCS group, while there were 29 eyes (44. 6%) and 32 eyes (49. 2%) in the Phaco group. The vision of SlCS group was better than that of Phcao group (χ2 = 4. 877, 5. 242, P < 0. 05 ). On postoperative 1 and 3mo, with acuity of 0. 5 or better, eye numbers showed no statistically significant differences between two groups (χ2 = 0. 005, 0. 085, P>0. 05). The average corneal astigmatism used analysis of repeatedly measuring designing variance: Comparing the corneal astigmatism in intra - groups at different times, it was statistically significant (F=25. 624, P<0. 05), and had a tendency to decrease with time. However, there was no statistical significance for corneal astigmatism between groups (F=0. 986, P>0. 05). The coneal astigmatism of each group was higher at 1wk after the surgery than that of preoperation, and the contrast had statistical sigenficence (t=2. 906, 2. 427, P<0. 05). The Phaco group with SlA was lower than the SlCS group at 1wk and 1mo after the surgery (t=-4. 628, 2. 770, P<005). lt had no statistical significance in SlA by comparing with the two groups at 3mo after the surgery (t=0. 754, P>0. 05). There were statistical differences in SlA at different time both by intra-group comparison and group comparison ( F=26. 37, P<0. 05, F = 14. 29, P<0. 05). The comparison of posterior capsule rupture, the postoperative corneal edema and anterior chamber pigment membrane reaction in two groups showed no statistical significance.
?CONCLUSlON: Our research shows that small-incision cataract surgery and phacoemulsification had similar effect in the treatment of cataract. Phacoemulsification is not the only surgery option for the best treatment effect. Small- incision cataract surgery can be popularized in basic- level hospitals, achieving the effect similar to phacoemulsification.

Objective To evaluate the capability and accuracy of multi-shce spiral computed tomography(MSCT)in detecting atherosclerotic plaques in nonstenotic coronary arteries with reference to the findings of intravascular ultrasound(IVUS)in a segment analysis.Methods Both IVUS exams and 16-row MSCT scans were performed on 35 consecutive patients among whom 30 patients had successful MSCT scans.A total of 94 coronary segments without significant coronary stenoses were paired-analyzed both on IVUS and MSCT segment by segment.The plaques were classified as calcified,fibrotic and soft types according to the echogeneity on IVUS.Plaque attenuation on MSCT was measured and expressed by Hounsfield units(HU).Results When referred to IVUS,MSCT had a sensitivity of 82.1%(46/56)and specificity of 89.5% (34/38),respectively in detectiong any plaques.For the detection of calcified plaques,the sensitivity and specificity were 92.1%(35/38)and 96.4%(54/56),respectively.For the detection of mixed and noncalcified plaques,MSCT had sensitivity of 73.2%(30/41)and specificity of 88.7%(47/53).But for the detection of the noncalcified plaque,the sensitivity was 66.7%(12/18). According to the findings On IVUS,the plaques were classified as calcified(n=19),fibrotic(n=19)and soft(n=16).The CT attenuation of calcified plaques was(489?169)HU(196 to 817 HU),fibrotic plaques(69?21)HU(25 to 117 HU)and soft plaques(23?18)HU(-12 to 47 HU).Nonparametric Kruskal-Wallis test revealed a significant difference of plaque attenuation among the three groups(P

Objective To evaluate the efficacy and safety of acute ureteroscopy for the treatment of ureterie stones during middle and late pregnancy.Methods From June 1998 to March 2005,17 pregnant women(mean age,27 years;age range,21-35 years)with ureteric stones were treated by ureteroscopy when the fetus was at 20-36 weeks of gestation(mean,29 weeks).All the cases presented with urgent symptoms such as recurrent renal colic(11 cases),fever(4)or acute obstructive anuria(2).Among 17 cases,the stones(between 6 mm?7 mm and 13 mm?21 mm)were located in the upper(8 cases),middle(5)or lower ureter(4);and on the left side(5 eases),on the right(10)and on both(2)of the lower ureter. Mild hydronephrosis were observed in 6 cases and moderate hydronephrosis in 11,Of the 17 cases,14 under- went ureteroscopic pneumatic lithotripsy;in 1 case the calculi were pushed to the renal pelvis;and 2 cases were treated by Double-J catheter drainage.Results All the urgent symptoms in 17 cases were relieved after treatment.The stone-free rate of initial treatment was 82.4%(14 of 17).Three cases with residual stones were treated by Douhle-J catheters,which were replaced every 3 months until the calculi were re- moved.No abortion,premature delivery or complications such as ureter perforation occurred.Mild renal colic occurred in 1 case after insertion of Douhle-J catheter,and it was relieved 3d later;gross hematuria occurred in l case and disappeared 6 d later without treatment.All 17 patients had normal delivery and gave birth to healthy children.Conclusions Ureteroscopy is a safe and reliable method for the treatment of ureteric calculi during middle and late pregnancy.
