Cervical cancer is the leading cause of cancer death in women in the developing countries.The treatment based on surgery,radiotherapy and chemotherapy is often accompanied by intolerable complications.Clinical practice has proved that TCM therapy has a positive effect on the complications related to the treatment of cervical cancer,but there is still a lack of scientific and standardized application reference opinions.Based on Delphi method,our research group constructed and formulated an expert consensus study on the complications related to the treatment of cervical cancer with TCM therapies,so as to provide a reference for clinical treatment of such diseases.

OBJECTIVE: To summarize the effectiveness of the temporal island flap pedicled with the perforating branch of zygomatic orbital artery for repairing defects after periocular malignant tumor resection. METHODS: Between January 2015 and December 2020, 15 patients with periocular malignant tumors were treated. There were 5 males and 10 females with an average age of 62 years (range, 40-75 years). There were 12 cases of basal cell carcinoma and 3 cases of squamous carcinoma. The disease duration ranged from 5 months to 10 years (median, 2 years). The size of tumors ranged from 1.0 cm×0.8 cm to 2.5 cm×1.5 cm, without tarsal plate invasion. After extensive resection of the tumors, the left defects in size of 2.0 cm×1.5 cm to 3.5 cm×2.0 cm were repaired with the temporal island flap pedicled with the perforating branch of zygomatic orbital artery via subcutaneous tunnel. The size of the flaps ranged from 3.0 cm×1.5 cm to 5.0 cm×2.0 cm. The donor sites were separated subcutaneously and sutured directly. RESULTS: All flaps survived after operation and the wounds healed by first intention. The incisions at donor sites healed by first intention. All patients were followed up 6-24 months (median, 11 months). The flaps were not obviously bloated, the texture and color were basically the same as the surrounding normal skin, and the scars at recipient sites were not obviously. There was no complication such as ptosis, ectropion, or incomplete closure of the eyelids and recurrence of tumor during follow-up. CONCLUSION The temporal island flap pedicled with the perforating branch of zygomatic orbital artery can repair the defects after periorbital malignant tumors resection and has the advantages of reliable blood supply, flexible design, and good morphology and function.

Objective:To analyze the difference of somatic mutation of DNA mismatch repair (MMR) protein deletion (dMMR) /integrity (pMMR) in colorectal cancer (CRC).Methods:A total of 93 cases of paraffin pathological tissue derived from CRC patients underwent surgical treatment and postoperative routine immunohistochemical diagnosed as dMMR in the Second Affiliated Hospital of Zhejiang University Medical College from January 2015 to January 2017 were collected and conducted the second-generation sequencing test. The expressions of 4 MMR proteins (MLH1, MSH2, MSH6 and PMS2) in CRC tissue were detected by immunohistochemistry method, and the immunohistochemistry results were re-interpreted according to the American Association of Pathologists (CAP) standard. Second-generation sequencing technology was used to detect somatic mutations of 41 genes in 93 cases of paraffin pathological CRC tissue, and Fisher′s exact test was used to analyze the gene mutation differences between groups.Results:After re-evaluation according to CAP standard, 31 cases were divided into pMMR group and 62 cases in dMMR group among the 93 CRC patients. The medium number of gene mutations in the dMMR group was 9.5, higher than 3.0 of the pMMR group ( P<0.001). Somatic mutation differences were found in 17 genes between the dMMR and pMMR groups, including breast cancer susceptibility genes 1 (BRCA1), BRCA2, MLH1, PDGFRA, PIK3CA, APC, ATM, KIT, MET, PMS2, MSH6, POLE, MSH2, PTCH1, epidermal growth factor receptors (EGFR), TP53 and ERBB2 genes. The pathogenic somatic mutation rates of BRAF, MLH1, MSH2 and MSH6 in the dMMR group were higher than those in the pMMR group [21.0% (13/62) vs 9.7% (3/31), 9.7% (6/62) vs 0 (0/31), 21.0% (13/62) vs 0 (0/31), 22.6% (14/62) vs 0 (0/31), P<0.05]. The mutation rate differences of BLM N515fs, BRAF V600E, PTCH1 R1308fs and KRAS G13D sites were statistically different between the dMMR group and the pMMR group [22.6% (14/62) vs 0 (0/31), 19.4% (12/62) vs 3.2% (1/31), 11.3% (7/62) vs 0 (0/31), 16.1% (10/62) vs 3.2% (1/31), P<0.05]. The mutation rates of 3 uncommon sites including BLM N515fs, MSH6 F1088fs and PTCH1 R1308fs were 28.2% (11/39), 15.4% (6/39) and 15.4% (6/39) in patients with dMMR who were missing MLH1 and PMS2 together, statistically different from all of 0 (0/31) in pMMR patients ( P<0.05). Conclusions:CRC Patients with dMMR have more related gene somatic mutations. The BRAF V600E mutation is closely related to dMMR. KRAS G13D, BLM N515fs and PTCH1 R1308fs mutation sites are also associated with the expression of MMR proteins.

Objective: To investigate the effects of free mini-flap on tibial side of third toe on repairing skin and soft tissue defect of finger pulp at the end of finger. Methods: From August 2013 to May 2017, 18 patients with skin and soft tissue defect of finger pulp at the end of finger were admitted to our unit, with 12 men and 6 women aged 16 to 54 years. As the skin and soft tissue defect sites, there were 3 cases of thumb, 8 cases of index finger, 4 cases of middle finger, and 3 cases of ring finger. The area of defects ranged from 2.0 cm×1.4 cm to 3.5 cm×2.4 cm. Free mini-flaps on tibial side of third toes were designed according to area and shape of defects, and the length and width of flaps were 0.1 to 0.2 cm longer than the length and width of the defects, respectively. The area of flaps ranged from 2.1 cm×1.5 cm to 3.7 cm×2.6 cm. The end-to-end anastomosis of subcutaneous veins of flaps and superficial veins of the finger-palm side or superficial dorsal digital vein, the end-to-end tension-free anastomosis of the base metatarsal arteries on tibial side of third toe and proper digital arteries of recipient finger were performed. Besides, anastomosis of base metatarsal nerve on tibial side of third toe and proper digital nerve of recipient finger was performed. The donor sites on feet were sutured directly or repaired with full-thickness skin grafts on medial upper leg of the same side. The survival of flaps after operation and the follow-up of patients were observed. Results: All flaps survived well, with good blood supply. Among the 18 patients, 2 patients lost to follow-up, and 16 patients were followed up for 4 to 36 months. The shape and texture of flaps were good. After reconstruction, finger pulps at the end of finger were plump, with fingerprint. Function of the finger restored well, and the two-point discriminatory distances of flaps were 5 to 10 mm. The donor sites on feet of 14 patients healed after the operation, the other 2 patients had necrosis on edge and central area of skin grafts, and the necrotic area healed after dressing change. The skin graft areas on feet were wear-resistant, with slight damage to donor sites and did not influence shoes wearing and walking. Besides, patients did not feel uncomfortable. Conclusions Skin and soft tissue defects of finger pulp at the end of finger repaired by free mini-flaps on tibial side of third toe are with good shape and slight damage to donor sites, and the operation is simple. It is worthy of popularization and application in clinic.

Objective: To explore the clinical effects of heel lateral flap in repair of skin and soft tissue defects at posterior heel region. Methods: From September 2007 to April 2016, 24 patients (17 males and 7 females, aged 16-70 years) with skin and soft tissue defects at posterior heel region were admitted to our department. The size of skin and soft tissue defects after debridement ranged from 3.0 cm×2.0 cm to 5.0 cm×4.0 cm. The defects were repaired with heel lateral flaps, with size ranging from 3.5 cm×2.5 cm to 6.0 cm×5.0 cm. The flaps were transferred to the donor sites through the loose subcutaneous tunnel. The donor site was repaired by full-thickness skin graft collected from inguinal region. The survival of flaps and the follow-up of patients were observed. Results: All flaps of 24 patients survived successfully. The recipient sites and donor sites were all healed. The patients all had follow-up of 6 to 24 months. At the last follow-up, the flaps were in good shape, with nearly normal color and soft texture. There were 6 cases of grade S3 sensation and 16 cases of grade S3⁺ sensation. The distance of two-point discrimination of flaps ranged from 6 to 11 mm. The lateral foot skin grafts healed well, and the skin of the lateral foot was numb in the range of 4.0 cm×2.0 cm to 9.0 cm×3.0 cm. Conclusions Heel lateral flap can not only repair the skin and soft tissue defects in the posterior region, but also reconstruct the sensory function of the posterior region. It is an ideal method to repair the skin and soft tissue defects in the posterior region.

Objective: To explore the effect of the perforator flap of the proper digital artery on the ulnar or radial side of the finger in the treatment of webbed scar contracture of the same finger in child. Methods: From January 2012 to January 2016, 26 children who were treated with dressing change after burn of finger and then had webbed scar contracture along with growth and development were hospitalized in our unit, involving a total of 50 fingers. There were 14 males and 12 females among the children aged from 2 to 14 years. After the scar was dissected and released, the wound area ranged from 1.6 cm×1.0 cm to 5.0 cm×2.6 cm. The perforator flap of the proper digital artery of the ulnar or radial side of the same finger was used to repair the wound. The flap area ranged from 1.8 cm×1.0 cm to 4.6 cm×1.8 cm. The donor sites were sutured directly. The residual wounds in donor and recipient sites were repaired by full-thickness skin graft collected from inguinal area/adjacent area or adjacent perforator flap. The postoperative development and function of the fingers were followed up and observed. The range of motion of the fingers was evaluated according to the Chinese Medical Association Hand Surgery Society′s upper limb functional evaluation trial standard, the Kantor Scar Cosmesis Assessment and Rating Scale was used to score the scar of finger, and the latest data were recorded. Results: The flaps and skin grafts survived successfully after operation. The patients were followed up for 6 to 24 months. The perforator flaps of the proper digital artery on the ulnar or radial side of the finger survived well at the latest follow-up, with good color and texture and a two-point discrimination distance of 9 to 12 mm. There was no contracture of the fingers, a little pigmentation in the skin graft area, no flexion deformity of the fingers, no lateral bending of the fingers to the flap-harvesting side, and no scar contracture at the webs of the fingers. Compared with that of healthy side, the development of finger was not obviously abnormal. The range of motion of the fingers was excellent in 38 fingers and good in 12 fingers, and the scar score of the fingers was 2-3 points in 31 fingers, 4-7 points in 15 fingers, and 8-10 points in 4 fingers. Conclusions The efficacy of perforator flap of the proper digital artery of the ulnar or radial side of finger in the treatment of the webbed scar contracture of the same finger in child is reliable, with high postoperative survival rate of the flap, better color and texture, and fewer complications, which can avoid the risk of re-contracture of the finger in a short period after operation, and does not affect the growth and development of the finger.

Objective: To explore the clinical effects of superior gluteal artery perforator island flap in repair of sacral pressure ulcer. Methods: From May 2012 to May 2017, 20 patients with sacral pressure ulcers (14 males and 6 females, aged 27 to 67 years) were admitted to our department. According to the consensus staging system of National Pressure Ulcer Advisory Panel in 2016, 6 cases were in 3 stages, 14 cases were in 4 stages, with the area of pressure ulcers ranging from 5.0 cm×4.0 cm to 10.0 cm×8.0 cm. After debridement and vacuum sealing drainage, the superior gluteal artery perforator island flaps were used to repair the pressure wounds, with the area of flaps ranging from 6 cm×5 cm to 13 cm×8 cm. The donor sites were sutured directly. The survival of flaps after operation, the healing of wounds, and the follow-up of patients were observed. Results: After surgery, flaps of 20 patients survived well without reoperation. The length of hospital stay of patients was 20 to 40 days, with an average of 25 days. Eighteen patients were followed up for 6 to 24 months, with an average of 12.2 months. The flaps were in good shape and elastic recovery. There were no complications such as seroma or hematoma in the donor sites. Both the patients and family members expressed satisfaction with the shape and texture of the flap and shape of hip. Conclusions The superior gluteal artery perforator island flap is reliable in blood supply and easy to rotate. The flap can carry a little muscle to increase the anti-infective ability. Moreover, the donor site can be directly sutured with slight damage. Thus, it is one of the good methods for repairing sacral pressure ulcers.

Objective: To explore the feasibility of preoperative designing for anterolateral femoral flap using three longitudinal and five transversal strategy. Methods: From September 2015 to January 2017, 71 patients (73 pieces) were treated using anterolateral thigh flap in the Affiliated Hospital of Zunyi Medical University. There were 48 males and 23 females, with the age of (36±18) years. The three longitudinal and five transversal designing was performed before operation. Portable Doppler ultrasound was used to detect the piercing-out position (P point) of perforators in Ⅰ, Ⅱ, Ⅲ, Ⅳ areas. The diameter, direction and length (lower subcutaneous segment of perforators) of perforators after leaving piercing-out position were observed during the operation. The piercing-in positions on superficial fascia and the dermis were observed. Results: The data of 71 adults (73 legs) were evaluated. Before and during the operation, all the perforations were found in Ⅰ, Ⅱ, Ⅲ and Ⅳ areas. The number of perforators in region Ⅰ was 1.32±0.33, with the diameter of perforator at the piercing-out position was (0.79±0.13) mm. The length of subfascial segment of perforators was (1.54±0.97) cm, and the direction was oblique superolateral. The number of perforators in Ⅱ region was 1.21±0.53, with the diameter of perforator at the piercing-out position was (0.63±0.13) mm. The length of subfascial segment of perforators was (2.25±0.54) cm, and the direction was oblique inferoanterior. The distance form piercing-in position to line L was (0.84±0.42) cm. The number of perforators in the Ⅲ area was 2.22±0.49, with the diameter of perforators at the piercing-out position was (0.53±0.12) mm. The length of subfascial segment of perforator was (1.96±0.44) cm, and the direction was oblique inferoanterior. The distance between piercing-in positions to line L was (0.74±0.51) cm. The number of perforators in region Ⅳ was 1.41±0.72, with the length of subfascial segment of perforators was (1.22±0.45) cm and the direction was oblique inferolateral. There were 27 cases with oblique perforators, accounting for 37% of the total number of thighs. Conclusions This three longitudinal and five transversal designing is helpful to detect the expenditure point in the anterolateral femoral region, and is assistant to skin flap designing.

Objective: To provide clinical guidance for clinical selection, through retrospective analysis for the advantages and disadvantages of superficial iliac circumflex artery and lateral circumflex femoral artery perforator flap in wound repair. Methods: From July 2016 to January 2018, 89 cases were repaired with superficial iliac circumflex artery or lateral femoral circumflex artery perforator flap, including 32 cases of superficial circumflex iliac artery perforator flap, 18 cases of upper limb, 6 cases of face and neck, and 8 cases of lower extremity. There were 52 cases of lateral circumflex femoral artery perforator flap, 21 cases of upper limb, 2 cases of neck, 3 cases of trunk, 26 cases of lower extremity, 5 cases of superficial circumflex iliac artery perforator flap combined with lateral femoral circumflex artery perforator flap, 3 cases of upper limb and 2 cases of lower extremity. The perforators of superficial circumflex iliac artery or (and) lateral circumflex femoral artery were detected by portable Doppler flow detector before operation. According to the wound size, the superficial circumflex artery perforator flap or (and) lateral circumflex femoral artery perforator flap was or (were) designed and resected. End-to-end or end-to-side anastomosis was performed in vascular pedicle. In the combined resection group, the end-to-end or end-to-side anastomosis of the perforator of the lateral circumflex thigh artery was performed, and the pedicled part of the superficial circumflex iliac artery was used for supercharging. Results: All the flaps survived successfully except one combined flap had tip necrosis on the superficial iliac circumflex artery perforator flap part. and healed after 2 weeks of dressing change. Venous crisis occurred on the first day after operation of superficial iliac circumflex artery perforator flap in 1 case.10 cases of lateral femoral circumflex artery perforator flap were slightly bloated and 3 cases returned to hospital for secondary thinning. All the flaps were soft in texture, satisfactory in shape and function, and numbed in the small area of the donor region of the perforator flap of lateral femoral circumflex artery in the early stage. All the patients had no severe complications after follow-up. Conclusions The perforator flap of superficial iliac circumflex artery and lateral femoral circumflex artery are ideal donor areas for wound repair. The perforator flap of superficial iliac circumflex artery is preferred for small area wound, hand wound and small bone defect. Lateral circumflex femoral perforator flap is suitable for all trunk and limbs with large or complex wounds.
