Objective To discuss the surgical method of resection of petroclival tumors used temporal base transtentorial approach.Methods Analyzed 26 cases of petroclival tumors.All of them were surgically treated under intraoperative neurophysiological monitoring by temporal base transtentorial approach.Firstly the supratentorial part of tumors were resected by pieces,and then the tentorium was cut open,in order to resect residue of the subtentorial part of tumors.This surgical maneuver was applied to reduce the retraction to surrounding vessels,nerves and brain stem,as well to protect important structures and to finally achieve radical removal of the tumors.The efficacy and complications were observed.Results Among 26 cases,19 cases (73.1%,19/26) achieved total removal,5 cases (19.2 %,5/26) achieved subtotal removal and 2 cases (7.7%,2/26) achieved great partial removal.There was no surgery-related death.Eleven cases suffered from partial neurological deficit.All cases were followed up for 3 months to 4 years,3 cases underwent complete recovery,4 cases underwent partial recovery,and 4 cases underwent permanent deficit.Conclusions Using temporal base transtentorial approach to resect petroclival tumors is convenient,applicable,safe and with minimal injury and with high proportionality of total resection.Under intraoperative neurophysiological monitoring,this approach may be an ideal choice for surgical treatment of these tumors.

OBJECTIVETo evaluate the safety and clinical outcomes of the novel simplified no-flip surgical approach to Shang Ring male circumcision in adults.
METHODSA total of 528 adult males, aged 18 - 58 (mean 35) years, 63 with phimosis and 465 with redundant prepuce, underwent no-flip Shang Ring circumcision with or without removal of the outer ring. The operation time and intraoperative blood loss were recorded and observations were made on such complications as postoperative bleeding, infection, edema, and wound dehiscence.
RESULTSThe operation time, intraoperative blood loss, and 2-hour postoperative pain score were (3.8 +/- 0.3) min, (0.6 +/- 0.1) ml, and 7.3 +/-0.3, respectively. Spontaneous ring detachment occurred at 21.6 +/- 2.1 days postoperatively in 12.7% of the patients (67/528) who had chosen not to remove the rings. Of those who preferred removal of the outer ring (87.3% [461/528]), none experienced any pain at the ring removal 7 days after the operation. Postoperative complications included infection in 3 cases (0.56%) and mild edema in 9 (1.70%), but no bleeding and wound dehiscence. Totally, 518 (98.1%) of the patients felt satisfied with the postoperative penile appearance.
CONCLUSIONNo-flip Shang Ring circumcision, with no need for removal of the inner ring, is a safe and simple approach for adult males, which is superior to conventional Shang Ring circumcision for requirement of fewer surgical instruments, shorter operation time, lower incidence of complications, and better satisfaction with the penile appearance. However, these advantages are to be further demonstrated by more randomized controlled trials.

Objective To investigate the feasibility and efficacy of laparoscopic orchiopexy for inguinal palpable undescended testes. Methods Ninety patients with 103 inguinal undescended pal-pable testes were treated by laparoscopic orchiopexy performed by the same surgeon. There were 24 (26.7 %) left and 53 (58. 9%) right palpable cryptorchidism cases, plus 13 cases (14.4 % ) with bilat-eral undescended testes. The mean age of the patients was 17 months (range 8 months-6 years). The surgical procedures were described as following. First, the peritoneum was opened at the anterior sur-face of the spermatic vessels and vas deferens before the testis was pulled into the abdominal cavity so that the spermatic vessels and vas deferens were released and easily manipulated. Second, the inter-space between internal spermatic fascia (transversalic fascia) and processus vaginalis was divided so, that the testis could be pulled into the abdominal cavity. Finally, the trocar which was inserted from scrotum was placed through the outer ring. Finally, the testis was placed at position and fixed. Re-suits The mean operative time was 32.7±5.2 min. The processus vaginalis unclose was found in 93 (90.3%) cases; and contralateral process us vaginalis unclose were found in 12 (15.6%) cases of 77 unilateral undescended testes. The complication rate was 3(3.3%)cases, all in bilateral cases. All 103 testes were descended by laparoscopy. On follow-up ranging 6-12 months, all testes maintained good size and a proper position. Conclusions The laparoscopic approach may be a safe way to descend the inguinal palpable testes. Orchiopexy of palpable undescended testes can be done with advantages in the laparoscopic approach.

Co-processed excipients withgelatinized or non-gelatinized starch were prepared by spray drying. Powder and tablet properties of corocessed excipients prepared were compared with those of physical mixtures and spray-dried lactose. Their applicability in traditional Chinese medicine (TCM) powder tableting was tested on two TCM extracts, i.e., the gardenia extract and the Herba Sedi extract. It was shown that gelatinizing starch before co-spray drying with lactose could improve the performance and efficiency of starch as a binder, resulting in remarkable improvement in physicomechanical properties of co-processed excipients prepared. Conpared to self-made and commercially available spray-dried lactose, co-processed excipients achieved better compactability and higher drug loading for TCM extracts. In conclusion, the lactose-gelatinized starch co-processed excipient, with excellent physicomechanical properties, is promising to be explored as a new excipient for direct tableting.
