OBJECTIVETo observe the therapeutic effect of supraclavicular island flap in repairing deep burn wound of neck.

METHODSSix patients with deep burn of neck hospitalized from January 2009 to June 2011 were enrolled in the study. Their total burn area ranged from 6% to 22% TBSA, of which full-thickness area ranged from 3% to 22% TBSA. The neck wound ranged from 12 cm x 5 cm to 15 cm x 8 cm in area, and they were all full-thickness in depth. One of the neck wounds was covered with granulation tissue. Patients underwent either debridement and escharectomy or excision of granulation tissue for the neck wound, and they were covered with supraclavicular island flap designed with the size corresponding to that of wound area. Four donor sites were sutured directly. The other two donor sites were covered with free skin graft. Survival of flaps and healing of donor sites were observed. The appearance and function recovery of operative regions were followed up.

RESULTSSupraclavicular island flaps of 6 patients survived as a whole. All the donor sites healed well. Flaps with satisfactory appearance and feeling sensation, accompanied by unlimited extension of neck were observed in the follow-up duration from 6 to 12 months. Scars observed in the flap edge and the donor sites were linear, and they did not affect the overall appearance and function of patients.

CONCLUSIONSSupraclavicular island flap is a good choice for repairing deep burn wound of neck, and it gives a good shape and function recovery of the neck.

AIM: To investigate the implication of respiratory microbiology on the efficacy of PD-1 inhibitors monotherapy for patients with NSCLC. METHODS: This study was designed as a retrospective study, fifty-eight patients with previously-treated advanced NSCLC who were received PD-1 monotherapy from October 2018 to October 2021 were included. The PD-1 inhibitors were consisted of camrelizumab, sintilimab and pembrolizumab. Additionally, the basic demographic data, therapeutic efficacy data, survival prognosis and adverse reactions during the PD-1 inhibitors treatment were collected and analyzed through the patients' medical records of the department and the electronic medical record system of the hospital. Furthermore, deep induced sputum specimens of the patients before treatment with PD-1 inhibitor were collected. And the respiratory microbiology of 58 samples were detected using 16S rRNA gene sequencing method. The index of respiratory microbiology α diversity was analyzed, and the correlation analysis was performed with the efficacy and prognosis of patients. RESULTS: A total of 58 patients with advanced NSCLC met the study's screening criteria and were evaluable for efficacy and safety profile. Efficacy data suggested that the objective response rate (ORR) and disease control rate (DCR) of the patients who received PD-1 inhibitors was 19.0%(95% CI: 9.9%-31.4%) and 55.2% (95% CI: 41.5%-68.3%). Furthermore, prognostic data obtained from follow-up indicated that the median PFS of the 58 patients with advanced NSCLC was 3.2 months (95% CI: 2.29-4.11) and the median OS was 10.5 months (95% CI: 5.58-15.43). Regarding the exploratory analysis between efficacy and respiratory microbiology, the 58 patients with NSCLC were divided into high α diversity group (group H) and low α diversity group (group L) according to Shannon diversity index of respiratory microecology detection. And the association analysis suggested that the ORR of patients with group H and group L was 23.3% and 17.9%(P c 0.380), respectively. Furthermore, prognostic analysis indicated that the median PFS of patients with group H and group L was 3.8 and 2.8 months, respectively, which was statistically significant (P c 0.034). CONCLUSION: PD-1 inhibitors monotherapy demonstrated preliminary efficacy and prognosis as subsequent line treatment for patients with advanced NSCLC. Patients with higher α -diversity of respiratory microbiology might confer a superior prognosis. And the conclusion should be validated in large sample prospective clinical trials subsequently.

BACKGROUNDTreatment of extensive post-traumatic composite bone and soft tissue defects remains a complicated therapeutic problem and a challenge for surgeons. We investigated the application of local flaps and Ilizarov osteogenesis in the reestablishment of severe combined defects of tibial bone and soft tissue.

METHODSSixteen patients with bone and soft tissue defects were included. The mean age of the patients was 31.5 years. The average time from injury to initial surgery was 14.4 weeks. The average soft tissue and bone defect sizes were 92.9 cm(2) and 8.7 cm, respectively. Local flaps were created to reconstruct the soft tissue defects. The Ilizarov external fixator or the Orthofix Limb Reconstruction System was used to reconstruct bony defects using delayed distraction osteogenesis.

RESULTSTwo myocutaneous flaps and 14 reverse island flaps were applied. All transferred flaps survived. Fifteen patients healed with equal leg length, and one healed with a residual leg-length discrepancy of 1.5 cm. One patient with an Ilizarov external fixator developed ankle joint stiffening and a pin-track infection that was successfully treated with oral antibiotics. No patient developed pin loosening. All patients walked without assistance. Fifteen patients returned to their work, and one lost her job. The results were evaluated using the Paley bone and functional assessment scores. The bone assessment results were excellent in 14 and good in two patients. Functional assessment scores were excellent in 13, good in two, and fair in one patient.

CONCLUSIONThe combination of local flaps and sequential distraction osteogenesis can be used for successful reconstruction of defects of incorporated bone and soft tissue.

OBJECTIVETo explore the mechanism of electroacupuncture therapy on Parkinson's disease (PD).

METHODSFifty Wistar rats were randomly divided into a normal group, a sham-operation group, a model group, a Fengfu-Taichong group and a Shuanggu Yitong group. PD model was duplicated by microinjection of 6-Hydroxyl-Dopamine into right corpora striata, and by microinjection of normal saline in sham-operation group. Rats in normal group, sham-operation group and model group were not treated. In Fengfu-Taichong group, the rats were treated by electroacupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) on the basis of the PD model, and by electroacupuncture at "Fengfu" (GV 16), "Taichong" (LR 3), "Guanyuan" (CV 4) and "Zusanli" (ST 36) in Shuanggu Yitong group, once daily for 2 weeks. GDNF and Ret expression were detected by immunohistochemistry and western blotting, respectively.

RESULTSThe number of GDNF positive cells and the content of Ret receptor increased significantly in the two electroacupuncture groups compared with those in the other groups (all P < 0.01), and the expression of GDNF increased significantly in Shuanggu Yitong group compared with that in Fengfu-Taichong group (P < 0.01).

CONCLUSIONElectroacupuncture can not only increase the expression of GDNF, but also enhance its effect. "Shuanggu Yitong" method is better than simple acupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) in increasing expression of GDNF.
