Traditional Chinese medicine has accumulated rich experience in treating dysfunction of gastrointestinal peristalsis. In recent years, a large number of studies have been made on the mechanism and effects of traditional Chinese medicines on the gastrointestinal peristalsis, and the concept of "gastrointestinal promoting Chinese medicine" has been advocated. These traditional Chinese medicines can be divided into three types: promoting the gastrointestinal peristalsis, inhibiting the gastrointestinal peristalsis, and bi-directional modulating. The in vivo and/or in vitro experiments showed that some of the traditional Chinese medicines for activating blood or regulating qi could promote the stomach peristalsis, and the traditional Chinese medicines for moistening intestines to relieve constipation or invigorating spleen to promote digestion could accelerate the intestinal peristalsis. The mechanism lies in the neuroregulation and gut-peptide regulation. Further research on multi-regulation and of multi-target should be done, for the mechanism of the traditional Chinese medicines in regulating the gastrointestinal peristalsis is far more complicated.

Objective To carried out rat as deep inferior epigastic perforator (DIEP) flap necrosis model,to reveal the continuous blood fluid change in process of flap necrosis.Methods Seven SpragueDawley rats of male were used.The designed DIEP flap model was pedicled on the right-sided cranial perforator.Near-infrared fluorescent angiography was performed using SPY imaging system pre-and-aft operation and all angiography videos were compared and analyzed.Results Using SPY imaging system could observe the process of the blood fluid scattered from perforator through choke anastomoses to next vascular territories in living body.The study could clearly observe sequence change of blood fluid pr-and-aft operation,which could give the important information in revealing the reason of necrosis in DIEP flap.Cross-midline traffic vascular sparse and eventually could no longer wear through the contralateral abdominal wall vessel area and open in the region of lateral thoracic vascular occlusion of blood vessels to reach the flap to the far left side,and showed no blood flow in the dark zone.Conclusion The reasons of necrosis of contralateral distal zone of the flap model,are the choke anastomoses across the midline to the contralateral side appeared small,less intensity and the blood supply to contralatral distal zone should through twice choke anastomoses.

OBJECTIVETo introduce the application of pedicled anterolateral thigh (ALT) flap for total penile reconstruction and to investigate its feasibility and effect.

METHODSFrom May 2011 to May 2015, 12 male patients presented with absence of the penis or congenital malformation received phalloplasty with the pedicled ALT flap. Of them, the median age was 35 years old (range, 20-57 years). The size of the flaps ranged from 11 cm x 11 cm to 12 cm x 15 cm. 8 patients underwent urethra reconstruction with tube-in-tube flaps and other 4 patients with scrotal septal flaps. In this series, we performed one-stage urethral anastomosis in 4 cases and second-stage urethral anastomosis 6 months after the phalloplasty in 8 cases.

RESULTSAn acceptable reconstructed phallus was achieved in 10 patients. These flaps were primarily healed with satisfactory functional and cosmetic results. The reconstructed penis was completely necrosis because of the flap failure in one case. The distal half of the phallus was lost due to infection in one case. Both of them were treated with pedicled ALT flap from the other side. Reliable results were achieved. At a median follow-up of 1.5 year (range 1 to 4 years), 9 patients (90%) were fully satisfied with phallic cosmesis and size, and 4 patients who was married had successful sexual intercourse. 8 patients had normal urinate function. Fistula was developed in 2 patients (20%) which was treated with delayed repair at 6-12 months with local scrotal flaps.

CONCLUSIONSThe pedicled ALT flap can be simply used to reconstruct an entire penis as well as a urethra. It has several advantages including a less conspicuous donor site, greater bulk, better color match and no necessary for microsurgery.

Objective To investigate a new method and to observe the clinical effect of repairing the lower eyelid ectropion assisted with the subcutaneous pedicle flap from temporal region. Methods Since 2007, 24 patients with lower eyelid ectropion were treated with the subcutaneous pedicle flap from temporal region which was the donor area without hairs, including 8 cases of scar infection, 6 cases of trauma, and 10 cases of tumor removal. Among the 24 cases of the flap, the maximum area was 5. 5 cm× 1. 5 cm,and the minimum was 4. 0 cm × 1.0 cm. Results All patients were followed up for 6 months to 3 years.All flaps survived completely with excellent texture and appearance. The donor site was hidden and no obvious malformation of the donor site was observed. Conclusions Because the blood supply of flap is reliable and the incision in the donor site is hidden, the subcutaneous pedicle flap from temporal region pedicled with arterial network of the outer canthus is an ideal donor site for repairing the lower eyelid ectropion with full thickness defects.

OBJECTIVETo discuss the methods for urethral external meatus and glanuloplasty after correction of hypospadias.

METHODSThe V shape flap on the dorsal side of glan, combined with the bilateral glan flaps were moved to the ventral side. The flap at the ventral side of urethral external meatus was turned over. Then the urethral external meatus was repositioned to the top end of glan with the ventral defects covered by the dorsal flaps. Then the coniform glan was reconstructed.

RESULTSFrom January 2008 to December 2013, 28 cases were treated, including glandular hypospadias, postoperative retraction of external urethral meatus and meatal stenosis. 21 patients were followed up for 1 -12 months (average, 1 month) with marked improvement of glan appearance and retraction of external meatus. No meatal stenosis happened.

CONCLUSIONSPostoperative retraction of urethral external meatus and meatal stenosis can be corrected by V shape flap on the dorsal side of glan combined with the bilateral glan flaps. The flat appearance of glan can be improved. It is an ideal method for glandular hypospadias.

Objective To investigate the application of the repeated expanded bilateral deltopectoral flap for resurfacing severe facial cervical scar, with review of relating articles to discuss issue of repeated expanding flap.Methods Nine patients suffered from hyperplastic facial and cervical scar.Two soft tissue expanders were implanted into the anterior chest region at both sides of sternum.The center of inner border of the expander was at the cross of second intercostal and parasternal line, and the lengthways axe of the expander was located at the ligature of the second intercostals and mammary areola.After two weeks when the expander was filled, expanded flap was transferred to cervical defect.The transferred flap was repeated expanded after half a year and transferred to resurface facial defect.Results In the first expansion stage, 600 or 800 ml expander were implanted in each side of sternum.In the second stage, 400 or 500 ml were used.The first stage of expanding process was smooth, and 2 of the expanding flaps were ruptured during the second expansion period.400-520 cm2 (average 440 cm2) additional expanded flap was acquired during two stages of expanding.Conclusions The repeated expanded bilateral deltopectoral flap gives us greater opportunity to repair severe facial-cervical scar.The best interval time of the two-stage expansion is over half a year.The speed of second expansion should be lower than that in the first stage, and protecting the expanding flap carefully from external force compression is needed during the second expasion.

AIM: To observe the changes of glycemia and serum cholesterol and triglyceride in diabetic nephropathy rats and therapeutic effects of Xiaoke Keli Ji. METHODS: 3/4 nephrectomy was adopted firstly, three weeks later streptozotocin(STZ) was administered intraperitoneally to establish diabetic nephropathy model in rats. Animals were divided into four groups:model group, Xiaoke Keli Ji treatment group, positive control group and sham group. Changes of serum sugar and serum creatinine, cholesterol and triglyceride were examined at 1, 2, 3, 4, 5 weeks after STZ injection. Renal tissue samples were adopted at 6th week and studied by light microscopy. RESULTS: Model group demonstrated different degree of glomerular sclerosis. Lesions in treatment group were alleviated. Serum creatinine, serum sugar and serum cholesterol were higher at 1, 2, 3, 4, 5 weeks after STZ injection in model group than that of the sham group ( P

OBJECTIVETo investigate the application of pedicled expanded flaps for the reconstruction of facial soft tissue defects.

METHODSThe expanded skin flaps, pedicled with orbicularis oculi muscle, submental artery, the branch of facial artery, superficial temporal artery, interior upper arm artery, had similar texture and color as facial soft tissue. The pedicled expanded flaps have repaired the facial soft tissue defects.

RESULTSBetween Jan. 2003 to Dec. 2013, 157 cases with facial soft tissue defects were reconstructed by pedicled expanded flaps. Epidermal necrosis happened at the distal end of 8 expanded flaps, pedicled with interior upper arm artery(4 cases), orbicularis oculi muscle(3 cases) and submental artery(1 case), which healed spontaneously after dressing. All the other flaps survived completely with similar color and inconspicuous scar. 112 cases were followed up for 8 months to 8 years. Satisfactory results were achieved in 75 cases. 37 cases with hypertrophic scar at incisions need secondary operation.

CONCLUSIONSIsland pedicled expanded flap with similar texture and color as facial soft tissue is suitable for facial soft tissue defects. The facial extra-incision and large dog-ear deformity could be avoided.

OBJECTIVETo compare the effect of three methods for penile reconstruction.

METHODSFrom Sept. 2000 to Dec. 2012, penile reconstruction was performed in 48 cases with free scapular flap transplantation, or pedicled superficial circumflex iliac artery skin flap, or anterolateral thigh skin flap pedicled with lateral circumflex femoral artery. The flaps were 12.0-14.5 cm in length, 10-12 cm in width and the urethra perimeter was about 2-3 cm.

RESULTSFree scapular flaps were used in 21 cases, with flap failure in 3 cases due to insufficient blood supply. Malleable penile prosthesis was implanted in 11 cases, which was exposed in 3 cases. Groin skin flaps were used in 21 cases, with flap failure in 8 cases due to insufficient blood supply. Malleable penile prostheses were implanted in 7 cases, which was exposed in 3 cases. Anterolateral thigh skin flaps were used in 6 cases, with flap failure in 2 cases due to necrosis and infection. No prosthesis was implanted in this group. All the failure cases underwent secondary reconstruction with successful results. 37 cases were followed up for 1-6 years, avevage 2.5 years. 26 cases were satisfied with the results of appearance and function.

CONCLUSIONSAmong these three methods, the free scapular flap is most recommended for its high survival rate, low complication rate and high patient satisfaction.

Objective: To investigate the therapeuctic effect of one-stage reconstruction of distal urethra with free graft of tublar oral mucosa. Methods: Two strips of oral mucosa graft( 0.4—0.6 cm in width), were harvested and sutured around an oiled silk roll to form mucosa tube. The mucosa tube was used to reconstruct distal urethra. Postoperative pressure dressing and earlier urination were recommended. Results: From May 2007 to October 2015, 16 cases with distal urethra defect or stenosis were treated with this method. The urethra defect was 2—4 cm in length. Urethral fistula happened in 3 patients. All the other 13 cases healed primarily. 10 cases were followed up for 1—5 years by telephone with normal function. Conclusions One-stage reconstruction with free graft of bulbar oral mucosa is suitable and reliable for distal urethra defect less than 4 cm in length.
