Chronic inflammatory demyelinating polyneuropathy (CIDP) with positive anti-contactin-associated protein-1 (Caspr1) antibody is a rare autoimmune antibody mediated peripheral neuropathy. A 62-year-old male patient was reported in this article, whose clinical manifestations were subacute onset, abnormal distal limb motor sensation, and increased cerebrospinal fluid protein level. The patient had a good response to plasma exchange. Electromyography of lower limbs showed that motor involvement was dominant, motor conduction velocity slowed down, compound motor active potential (CMAP) and sensory nerve active potential amplitude decreased, and F wave was not elicited; electromyography of upper limbs without symptoms showed that CMAP amplitude of median nerve decreased, and conduction velocity was normal. There are few reports of anti-Caspr1 positive CIDP in the world. The article summarized the characteristics of the patient and reviewed the relevant literature, in order to improve clinicians′ understanding and diagnosis and treatment ability of the disease.

Objective To describe the single needle running suture method for the urethrovesi-cal anastomosis during laparoscopic radical prostatectomy(LRP). Methods Forty-five patients of prostate cancer underwent LRP with the single needle running suture method. The technique was initi-ated by performing a fixing suture at the posterior lip of bladder neck at 4 o' clock and tying the first knot. Another suture at the nearby position of the first suture was performed to leave the first knot outside. From 5 o' clock to 8 o' clock, sutures were performed every one o' clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were per-formed every 3 sutures. After completing the full circumference, the needle was drawn at the 2 o' clock for the second knot. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. Any remaining leakage could be closed with additional interrupted su-tures. Results All urethrovesical anastomosis were completed successfully. The mean anastomosis time was 16 rain(from 12 to 25 min), and mean operative time was 132 rain (112 to 185 rain). The mean catheterization time was 9 d(7 to 14 d). Three temporal urinary leaks requiring prolonged cathe-terization were identified. Forty-four patients had total urinary control in 1 year postoperatively and no other short-term or persistent complication was found with a mean follow-up of 21 months. Conclu- sion The single needle running suture method could be a simple and safe method for urethrovesical anastomosis during LRP.

The single needle method for urethrovesical anastomosis with strengthened posterior fixation during laparoscopic radical prostatectomy was explored. The method was initiated by performing a fixing suture with a knot at 4 o'clock of the posterior lip of bladder neck, and another suture at nearby position was performed to leave the knot outside. From 5 o'clock to 8 o'clock, sutures were performed every one o'clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were performed every 3 sutures. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. After completing the full circumference, the needle was drawn near the 4 o'clock and tied at the tail end. Any leakage could be closed with additional interrupted sutures. The clinical data of 89 patients who underwent this method were retrospectively compared with those of 23 patients who underwent the single knot method. The results showed that the anastomosis, operative and catheterization time was 17.6+/-4.7 min, 134.0+/-10.7 min and 6.5+1.6 days respectively. There were 3 temporal urinary leakages identified in 89 cases requiring prolonged catheterization. No urinary leak and anastomotic stricture was confirmed, and 95.2% patients had total urinary control. It was concluded that this method was simple and safe for urethrovesical anastomosis.

The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (P<0.05), but no correlation was found between MRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (P<0.05). Meanwhile, the correlation between the KAI1/CD82 expression and MRP-1/CD9 expression was statistically significant (r=0.316, P<0.05). It was concluded that KAI1/CD82 and MRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.
