Objective To investigate the bioactivities of controlled release bFGF microspheres (Ms) and their effects on the cultured osteoblasts. Methods The secondary cultured osteoblasts were divided into four groups according to the different ingredients being added to the DMEM culture medium, ie, control group,bFGF group, bFGF-PLGA-Ms group and bFGF-PELA-Ms group. The proliferation of the cultured osteoblasts was measured with cell counting method, MTT method and flow cytometry. The content of bone BGP secreted by osteoblast was also measured with RIA method. Results The in vitro cellular study showed no significant difference in the cell number and cell viability of four groups one day after plate culture.The cell number and cell viability in the bFGF-PLGA -Ms group were more than those in other three groups four and six days after plate culture. The cell number and cell viabilitythose in the bFGF group were more than those in the bFGF-PELA-Ms group six and eight days after plate culture with insignificant difference. The flow cytometrical examination showed that the G 2/M+S percentage in the bFGF group reached the highest two days after plate culture and the G 2/M+S percentage in the bFGF-PLGA-Ms group went the highest four and eight days after plate culture. Among four groups, the content of BGP in the bFGF-PLGA-Ms group was the highest and the bFGF-PELA-Ms group the next. Conclusions The effect of bFGF-PELA-Ms is not satisfactory,as indicates that the manufacturing method needs improving. However,the bFGF-PLGA-Ms can promote the proliferation and differentiation of the osteoblasts through a long period of controlled release of bFGF.

AIM: To observe the effect of crocetin on the apoptosis and the changes of its related regulating proteins caspase-3 and Bcl-2 expression induced by hydrogen peroxide (H_2O_2) in cultured cardiomyocytes. METHODS: Changes of cellular morphology were detected under microscope. Apoptosis rates of the cells were analyzed by PI staining with flow cytometry. Expressions of caspase-3 and Bcl-2 proteins in the cells were determined by immunofluorescence with flow cytometry. RESULTS: In the concentrations used, more severe morphological changes with higher apoptosis rate of the cultured myocardial cells were seen in each H_2O_2 group than that in control group. When treated with 1?10 -4 mol?L -1 H_2O_2, the caspase-3 was increased and Bcl-2 protein decreased remarkably in the cells. But each dosage of crocetin, especially the highest one (5?10 -5 mol?L -1, P

Objective To present our experience of dealing with complete penile amputation.Methods Two cases of penile complete amputation were reported.The first case was a 34-year-old man,suffered amputation of the penis approximately 2.5 cm distal from the pubic area with a sharp knife.3.5hours later,the patient was transferred to our hospital.The urethra mucosa and corpus spongiosum were anastomosed.The cavernous body of the penis was reattached by suturing the tunics albuginea of each corpus cavernosum to the corresponding proximal segment.One dorssl artery,two dorsal veins,and dorsal nerve were anastomosed under a 10 × microscope with interrupted 9-0 nylon nonabsorbable sutures.The second case was a 25-year-old man,presented to the emergency room 15 hours after distal penile amputation,which had 2 wounds as a result of self-mutilation caused by psychiatric problems.The urethra mucosa and corpus spongiosum were anastomosed.The cavernous body of the penis was reattached by suturing the tunics albuginea of each corpus cavemosum to the corresponding proximal segment using 4-0 polyglactic acid sutures.Results In the first case,the tourniquet was released after replantation,and the distal penis appeared to revascularize,as noted by the gradual increase in redness and size.An arterial pulse was detected,and the superficial penile veins displayed normal turgor,and no bleeding was found.On postoperative day 3,the penile skin started to necrotize.On day 12,the necrotic skin was superficially debrided,and a fistula was observed in the corresponding urethral segment.Two weeks later,the fistula was sutured with 4-0 interrupted synthetic absorbable suture,and a transposition flap to embed the whole injured penis shaft was created from the proximal scrotal skin.The glans was exposed.Two months after the second operation,the embedded penis was released from the scrotum.After follow-up of two years,the patient had glans re-epithelialization with normal voiding,sensation,and erections.In the second case,the glans was still pink,but the penile skin started to necrotize on postoperative day 3.On day 14,serious infections were noted,the necrotic skin was superficially debrided,and the amputated penis was relieved.Conclusions Prompt diagnosis and early treatment are essential to avoid the potential complications of ischemic necrosis and autoamputation.Venous outflow is a critical factor for success of replantation.Microsurgical reanastomosing of the dorsal penile vein,penile arteries,and dorsal nerves can be identified as the standard method for penile replantation.The bipedicled scrotal flap can provide adequate skin cover for penis defects.

Objective To investigate the effects of antithyroid drug(ATD) on oxidative stress in Graves disease patients with and without infiltrative ophthalmopathy.Method The levels of superoxide dismutase(SOD),glutathione peroxidase(GPx) and catalase(CAT) in erythrocytes of Graves disease patients(18 with and 20 without infiltrative ophthalmopathy) were measured before and after treatment with ATD.Results Compared with the normal control group,the levels of SOD,GPx and CAT were significantly higher in Graves disease patients with and without infiltrative ophthalmopathy.After euthyroidism was achieved with the treatment of ATD,the levels of SOD,GPx and CAT were normalized in the patients without infiltrative ophthalmopathy,but oxidative stress was still present in the patients with infiltrative ophthalmopathy.Conclusion The oxidative stress is obvious in patients with Graves ophthalmopathy,which suggests that oxidative stress is involved in orbital inflammation.

Despite recent clinical guidelines, the optimal therapeutic strategy for the management of refractory chronic cough is still a challenge. The present systematic review was designed to assess the evidence for efficacy and safety of gabapentin in the treatment of chronic cough. A systematic search of PubMed, Embase, Cochrane Library databases, and publications cited in bibliographies was performed. Articles were searched by two reviewers with a priori criteria for study selection. Seven relevant articles were identified, including two randomized controlled trials, one prospective case-series designed with consecutive patients, one retrospective case series of consecutive patients, one retrospective case series with unknown consecutive status, and two case reports comprising six and two patients, respectively. Improvements were detected in cough-specific quality of life (Leicester Cough Questionnaire score) and cough severity (visual analogue scale score) following gabapentin treatment in randomized controlled trials. The results of prospective case-series showed that the rate of overall improvement of cough and sensory neuropathy with gabapentin was 68%. Gabapentin treatment of patients with chronic cough showed superior efficacy and a good safety record compared with placebo or standard medications. Additional randomized and controlled trials are needed.

Objective To investigate the clinical characteristics and therapeutic methods of bac-terial colonization and infection of Acinetobacter baumannii on the wound of earthquake induced patients. Methods A retrospective study was done on 42 Wenehuan earthquake induced patients with positive wound germiculture of Acinetobacter baumannii. There were 24 males and 18 females, at mean age of 37 years (12-96 years). Open injury was located at the upper arm in one patient, at the forearm in four, at the thigh in 12, at the calf in 23 and at the trunk in two. The time between injury and treatment varied from 3 to 7 days. The clinical characteristics including the bacteria identification and drug sensitivity test were studied to compare drug resistance to 15 antibiotics. Results Bacterial colonization of Acineto-bacter baumannii was found in 31 patients (8.2%) and infection of Acinetobacter baumannii in 11 (2.9%). After debridement, pruphylactic antibiotics and nutrition support, 15 patients with bacterial colonization were managed with Ⅱ stage suture or skin grafting. The other 16 patients were transferred to hospitals of other provinces after germiculture turned negative. Through debridement and drainage, antibi-otic therapy and nutrition support, the infection was controlled and the wound eliminated in six patients through Ⅱ stage suture but four were concomitant with pulmonary infection and one with septicemia. Drug sensitivity test showed that sensitive rate to imipenem, amikacin, levofloxacin, ticarcillin-clavulanic acid, tobramycin were 59.5%, 21.4%, 21.4%, 19.5% and 19.0% respectively. Conclusions The risk factors of infection of Acinetobacter baumannii include severe tissue trauma, severe wound contamination, delayed treatment and weak body resistance. During treatment, the bacterial colonization and infection of Acinetobacter baumannii should be distinguished and treated respectively. Correct wound treatment, suit-able antibiotic therapy and increased body resistance are key to improvement of clinical curative effect.

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.
