Objective:To compare the mental health between the urban mothers and rural mothers of children with cleft lip and pal-ate.Methods:1 68 mothers(including 1 24 rural and 44 urban)of the children with cleft lip and palate were included in the trial group and 82 mothers of normal children were included in the control group.The subjects were tested by the self-assessment symptom lists of SCL-90 for the evaluation and comparison of mental health.Results:The scores of nine dimensions of trial group in somatization, forcing symptoms,depression,anxiety,etc were significantly higher than those of the control group(P <0.05).The scores of nine di-mensions of rural group in somatization,forcing symptoms,depression,anxiety,etc were higher than those of the urban group,the ri-val,psychotic and total scores showed significant differences(P <0.05);Conclusion:The mental health status of mothers of children with cleft lip and palate is poorer than that of those of normal children.That of the rural mothers is poorer than that of the urban ones. Special attention should be paid to the mental health status of the parents of children with cleft lip and palate.

AIM: To study the effect of cGMP-dependent protein kinase (PKG) on the pathogenesis of burn shock. METHODS: Confluent endothelial cells were disintegrated and centrifugated to obtain cell lysates after being treated with 10% burn serum or PKG activator 8-Br-cGMP. PKG activity of lysates was measured with radioactive isotope label method in a reaction system of phosphorylation of specific substrate H2B by PKG, and the shape and the distribution of intracellular filamentous actin were detected by specific fluorescence staining. For the control study, the PKG specific inhibitor KT5823 were used to pretreat the endothelial cells before the administration of burn serum or PKG activator 8-Br-cGMP. RESULTS: Exposures to burn serum and 8-Br-cGMP led to a rapid time-dependent increase in endothelial PKG activity and the polar distribution of intracellular filamentous actin, and preincubation with KT5823 abolished those effects. CONCLUSIONS: The results suggest that burn serum induces PKG activation and the stress variety of filamentous actin in the vascular endothelial cells, which probably contributes to the endothelial hyperpermeability after burn shock.

Purpose To investigate the expression and significance of epiderma1 growth factor receptor( EGFR)mutation-specific anti-bodies in 1ung adenocarcinoma. Methods Immunohistochemica1( IHC)technique was used to detect the expression of EGFR muta-tion-specific antibodies(EGFR-19,EGFR-21)and EGFR tota1 protein antibody(EGFR-P)in 171 cases of 1ung adenocarcinoma with resected specimens,and EGFR gene mutation was a1so performed by amp1ification refractory mutation aystem-PCR( ARMS-PCR). The expression of EGFR-19,EGFR-21 and EGFR-P mutant proteins was compared with EGFR gene mutation and their re1ationship with histo1ogica1 c1assification and c1inica1 characteristics were ana1yzed. Results The expression of EGFR mutant protein was corre1ated with the poor differentiation group inc1uding micropapi11ary and so1id predominant types( P=0. 021 ). EGFR-21 high expression was re1ated to p1eura1 invasion(P=0. 005). The coherence of IHC(with EGFR-19/21 antibodies)and ARMS-PCR was existed(Kappa>0. 4 ). Taking ARMS-PCR as a standard,the sensitivity and specificity of EGFR-19 and EGFR-21 were 65. 0% and 89. 4%, 70. 0% and 97. 6%,respective1y. Conclusions Expression of EGFR mutation-specific antibodies is associated with poor differentia-tion and p1eura1 invasion. It suggests a worse prognosis indicator in 1ung adenocarcinoma. Because of the coherence with ARMS-PCR, using IHC with mutation-specific antibodies to detect the mutant proteins of EGFR-19/21 may act as a pre1iminary screening method of EGFR gene mutation.

OBJECTIVETo explore the feasibility and the effect of free chimeric perforator flap with deep inferior epigastric artery for the soft tissue defect on the lower extremity with deep dead space.

METHODSFrom Mar. 2010 to Aug. 2011, 8 patients with soft tissue defects on the lower extremities combined with dead space, bone or joint exposure were reconstructed with free hinged perforator flaps with deep inferior epigastric artery. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The defects on the donor sites were closed directly.

RESULTSAll the flaps survived with primary healing. Good color and texture was achieved. The patients were followed up for 12-24 months, with an average of 16 months. 2 over-thick flaps were treated by flap-thinning surgery. Only linear scar was left on the donor site on abdomen with no malfunction.

CONCLUSIONSThe free chimeric perforator flap with deep inferior epigastric artery can simultaneously construct the dead space and superficial defect with only anastomosis of one set of vascular pedicle. It is an ideal method with good results on recipientsites and less morbidity on donor sites.

Objective To explore the optimization of intubations for severe brain injury patients in ICU. Methods Seventy-six severe brain injury patients were divided into research group and traditional group through the envelop method, with 38 patients in each group. Patients in research group was induced by dexmedetomidine, while patients in traditional group was induced by midazolam or propofol. Throat and intratrachea surface anesthesia was taken with 3 ml of 1%lidocaine on two groups before intubation, and they were intubated through direct laryngoscope. Patients were connected with breathing machines after intubation, and the arterial carbondioxide partial pressure was maintained at 30-35 mmHg (1 mmHg=0.133 kPa). Intubations time, one-time success rate, cardiovascular reaction index, myocardial damage and heart failure biomarkers, adverse reaction, patients comfort and intubationists satisfaction of the two groups were compared. Results The intubation time on research group was significantly shorter than that on traditional group [(27.1 ± 14.2) s vs. (42.2 ± 18.7) s], and there was statistical significance (P<0.01). The one-time success rates in two groups was not statistically significant (P>0.05). The heart rates and mean arterial pressure (MAP) at pre-intubation, post-intubation, 5 min after intubation and 10 min after intubation in research group were significantly lower than those in traditional group:heart rate:(77.8 ± 8.5) bpm vs. (85.1 ± 7.6) bpm, (85.3 ± 9.1) bpm vs. (106.4 ± 12.5) bpm, (84.4 ± 10.4) bpm vs. (96.4 ± 11.9) bpm, (80.5 ± 12.1) bpm vs. (89.0 ± 10.5) bpm;MAP: (82.6 ± 10.1) mmHg (1 mmHg = 0.133 kPa) vs. (93.2 ± 14.3) mmHg, (88.3 ± 13.2) mmHg vs. (113.7 ± 15.1) mmHg, (85.4 ± 14.0) mmHg vs. (101.3 ± 9.9) mmHg, (83.7 ± 10.7) mmHg vs. (90.3 ± 13.4) mmHg, and there were statistical significances (P<0.05). There was no statistical significance of SpO2 between groups at every time point (P>0.05). For 6 and 12 h after intubation, creatine kinase isoenzyme MB (CK-MB), cardiac troponin T (cTnT) and brain natriuretic peptide (BNP) levels in research group were significantly lower than those in traditional group:CK-MB:(30.5 ± 7.2) U/L vs. (35.2 ± 10.1) U/L, (25.7 ± 5.7) U/L vs. (27.7 ± 6.5) U/L;cTnT:(0.6 ± 0.2) μg/L vs. (0.8 ± 0.1) μg/L, (0.5 ± 0.2) μg/L vs. (0.6 ± 0.2) μg/L;BNP:(152.6 ± 13.7) pg/L vs. (189.4 ± 19.3) pg/L, (89.7 ± 27.5) pg/L vs. (111.8 ± 20.4) pg/L, and there were statistical significances (P<0.05). There were no significant adverse reactions in two groups after topical anesthesia. The comfort and intubationists satisfaction scores in research group were significantly higher than those in traditional group: (2.5 ± 0.4) scores vs. (1.8 ± 0.5) scores and (8.8 ± 1.1) scores vs. (7.1 ± 0.9) scores, and there were statistical significance (P<0.01). Conclusions Combining dexmedetomidine induction with topical anesthesia to intubate is safe and effective, which is the optimization of tracheal intubations to severe brain injury patients.

Objective To explore the safety and clinical effect of the human acellular nerve allograft (hANG) for repairing peripheral nerve defects.Methods During November,2009 to October,2010,6 patients with 3 digital nerve defects and 3 radial nerve defects were repaired with hANG.During postoperation period,safety was evaluated by local wound response and laboratory testing,while the efficacy was evaluated by British Medical Research Council sensory function assessment standards,static 2-point discrimination (2PD) and Semmes-Weinstein monofilament testing.Results Three patients with 6 digital nerve defects received hANG transplant.The length of nerve graft was 20-50 mm(mean 30.8 mm).After followed up for 31-40 months,the excellent rate of 2PD was 66.7％.Two of 3 patients rahabilited as well as the normal.Three patients with radial nerve defects,whose length of nerve graft was 35-60 mm(mean 48.3 mm).The strength of extensor carpiradialis longus muscle had restored Ⅲ in 1 case,and other 2 cases had no restoration.Conclusion hANG is safe and effective for repairing peripheral nerve defects,especially for digital nerve defects.

Objective To explore the clinical effect and experience of separating deep circumflex iliac artery osteocutaneous perforator flap (DCIAP) from the bone flap.Methods According to local applied anatomy of groin,vascularized chimerical flaps of deep iliac circumflex artery was designed and applied.From May,2008 to June,2012,12 patients who combined bone and composite skin and soft-tissue defects were positioned by color dopplar ultrasound before operation and treated with vascularized chimerical flaps of deep iliac circumflex artery.The deep circumflex iliac perforator flaps was 8 to 19 cm in length and 2 to 6 cm in width,and the iliac bone grafts ranged from 5 to 8 cm in length.Results All flaps were fully survival.After 8-10 months postoperative followed-up,all the bone defect gained healing.The function and appearance of cutaneous flaps were satisfactory.There was no serious complication in donor sites of groin.The average time of healing was 9 (8-10) months.Conclusion Vascularized iliac bone graft and a perforator flap are nourished by the same deep circumflex iliac artery.There is more mobile scope and only 1 blood vessel between the bone graft and skin flap,which should be called chimeric perforator flap based on the deep iliac circumflex artery,and is a kind of good method to repair bone and soft-tissue defects of limbs.

Objective To investigate the clinical results,indications and precautions of a variety of special forms of the perforator flap for reconstructing limb soft-tissue defect.Methods From January 2008 to December 2013,480 cases suffering from limb soft-tissue defect were treated with special forms of the perforator flap.Types of special forms of the perforator flap included flow-through perforator flaps,micro-dissected perforator flaps,conjointed perforator flaps,polyfoliate perforator flaps and chimeric perforator flaps.Derivative types combined two or three technologies used in basic types.Results Venous crisis of the flap was shown in 10 cases.Through a second surgical exploration,5 cases were diagnosed with anastomotic thrombosis,2 with vascular torsion and 3 with hematoma.After appropriate treatments,flaps survived in 4 cases,but partial necrosis occurred in 6 cases.Twelve cases were found to have infection,which led to arterial crisis followed by total flap necrosis in one of them at postoperative day 5.Other flaps survived and wounds healed by first intention.Donor sites were repaired by skin flap transfer in 8 cases,skin grafting in 3 cases and direct suture in the rest cases.Conclusion Special forms of the perforator flap are optimal for repair of soft-tissue defect of extremities.

Objective To describe a technique to achieve primary donor-site closure, extend applications and minimize donor-site morbidity by applying the double skin paddle principle.Methods All 16 cases of the double skin paddle anterolateral thigh perforator flap reconstruction from May, 2008 to June, 2014 were reviewed.Defects locations included calf, dorsum pedis or planta pedis.A long anterolateral thigh perforator flap was marked out using standard points of reference.At least two separate cutaneous perforator vessles were identified on hand-held Doppler.Separating and dissecting flap at superficial layer of fascia lata was adopted in all cases.Then skin paddle was then divided between the two cutaneous perforators to give two separate paddles with a common vascular supply which was the descending branch of the lateral circumflex femoral artery.The skin paddles could be used to cover complex skin defects, whilst still allowing for primary donor-site closure.Results Fifteen patients were successfully treated with the double skin paddle anterolateral thigh perforator flap with no major complications.One case was suffered with partial skin flap necrosis.The type A dumbbell-like flaps was used to cover defects involving two different units of the foot.The type B pattern were stacked side by side on a flap inset, effectively doubling the width of the flap, to resurface a large defect of a single unit of the calf.The type C pattern was used to repair adjacent skin defects.In all cases, the donor site was closed directly.All patients were satisfied with their outcomes.Conclusion The double skin paddle anterolateral thigh perforator flap is an excellent method of resurfacing large defects of the extremity involving multiple subunits with improved morbidity and cosmesis of the donor site.

Objective To explore the feasibility and clinical effect of modified peroneal artery perforatorbased propeller flap which excludes small saphenous vein and sural nerve for coverage of the soft tissue defects of the ankle and foot.Methods From January,2009 to August,2013,20 patients with soft tissue defects of the foot or ankle underwent the procedures of reconstruction.After the proper perforators being identified with doppler sonography,the propeller flap was designed,which selected the location where terminal perforator vessels perforate deep fascia as the pivot point,the line from this point to the point where the second perforator near the wound around the line from the midpopliteal point to the midpoint of the achilles tendon and lateral malleolus perforated the deep facia as the axis.The flap was raised above the level of the deep fascia.The small extrinsic vessels around the sural nerve and small saphenous vein were contained in the flap,while the small saphenous vein and sural nerve were kept in the original position.The donor site was closed directly.The skin flaps measured from 7 cm × 4 cm to 21 cm × 7 cm.Results All 20 flaps survived completely without complications.During 10-28 months' followed-up (average 13 months),all flaps showed good texture matches and contour.All patients recovered walking and shoe wearing function.No one showed sensory disturbances at the lateral foot.Conclusion The modified peroneal artery perforator-based propeller flap excluding small saphenous vein and sural nerve still has stable blood supply,which is an idea way for covering skin and soft tissue defects in foot and ankle.
