Early diagnosis of sepsis helps make effective clinical decisions and improve the survival rate of patients with severe infection. However, the timely and accurate diagnosis of sepsis is still a great challenge in clinic. In order to settle the very problem, the scientists in the world have made a lot of exploration and research in the field of rapid molecular identification of pathogens. Nowadays, the nucleic acid detection of sepsis is mainly composed of 3 types of methodological strategies, either based on positive blood culture, single colonies, or directly on blood specimens. This paper presents a comprehensive overview of advances in the research of early detection of bacterial nucleic acid as molecular diagnosis of sepsis.

OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.
METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.
RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).
CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

OBJECTIVETo study the blood pressure (BP) changes in the liver transplant recipients.
METHODSA total of 206 patients without preoperation hypertension received liver transplantation in our hospital from February 2001 to July 2005. The BP level and serum immunosuppressant concentration at preoperation and various time points post operation were determined.
RESULTSCompared with the preoperation, the average systolic and diastolic pressure was significantly increased at the 2 week, 1, 2, 4 and 6 months post operation. The mobility of hypertension increased significantly after liver transplantation, with the highest mobility (46.49%) at the 1st month post operation. There was no linear correlation between the immunosuppressant (FK506) concentration and the BP level at any time point.
CONCLUSIONThere was a high hypertension incidence after liver transplantation. Although the use of immunosuppressive drugs accompanied with the BP increase, there was no linear correlation between the immunosuppressant concentration and the BP level post operation.

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.

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.
