Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To estimate the hospitalization rate of Haemophilus ( H.) influenzae associated community-acquired pneumonia in children under 5 years in Suzhou. Methods:From 2010 to 2014, medical records and bacteriology results of children under 5 years hospitalized with community-acquired pneumonia in Children's Hospital of Soochow University were collected, retrospectively. Detection rate of H. influenzae was describe. The hospitalization rate of H. influenzae associated community-acquired pneumonia was estimated using the number of local children in urban area of Suzhou, which was obtained from the immunization platform of Suzhou Center for Disease Prevention and Control. Results:A total of 28 043 hospitalized pneumonia cases were included from 2010 to 2014, in which 19 526 (69.63%) had bacteriological examination. The overall detection rate of H. influenzae was 11.06% (2 160/19 526), and children aged 12-23 months had the highest positive rate (14.29%, 550/3 850), and the rate was higher during winter-spring than during summer-autumn ( χ 2=455.11, P<0.01). The average hospitalization rate of H. influenzae associated pneumonia in children under 5 years was 760.36/100 000 (95% CI: 733.70/100 000-787.01/100 000), which was higher in winter and spring (898.79/100 000 and 1 249.52/100 000) than in summer and autumn (514.35/100 000 and 359.04/100 000), and the hospitalization rate was higher in boys (942.12/100 000) than in girls (563.76/100 000), the differences were all significant ( P<0.01). The highest hospitalization rate was observed in children aged 1-5 months (2 478.31/100 000) and the hospitalization rate decreased with age ( χ 2=2 129.80, P<0.01). Conclusion:There was a considerable burden of H. influenzae associated community-acquired pneumonia in children under 5 years in Suzhou, especially in children under 6 months.

Objective To evaluate the efficacy of pregabalin combined with nerve block on postherpetic neuralgia (PHN). Methods 60patients were assigned into group A (n=30), who received pregabalin orally, and group B (n=30), who received nerve block (trigeminalnerve, intercostal nerve, lumbar nerve block) in addition. They were assessed with visual analogue scale (VAS) of pain, sleep score fromHamilton Rating Scale for Depression before and 3 d, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, and 8 weeks aftertreatment. The incidence of pain decreased >50% and >30% were compared. Results The scores of VAS and sleep significantly reduced inboth groups 1~8 weeks after treatment (P<0.01), and decreased significantly 3 d after treatment in group B than in group A (P<0.05). The incidenceof pain decreased >50% and >30% were more in group B than in group A (P<0.05). Conclusion Nerve block combined with oralpregabalin is more effective on PHN.

Objective To observe clinical efficacy of intra-articular injection of sodium hyaluronate(SH) and betamethasone accompanied with Bulleyaconitin A or diclofenac sodium administration for severe knee osteoarthritis(KOA).Methods60 patients with severe KOA from 580 subjects with KOA were selected as observational subjects in the experiment. All patients were treated by intra-articular injection of sodium hyaluronate 2.5 ml and betamethasone administration once a week for five consecutive weeks as a therapeutic course, betamethasone only once. Bulleyaconitin A group was accompanied with Bulleyaconitin A 0.4 mg, t.i.d, p.o.; diclofenac sodium group was accompanied with diclofenac sodium 75 mg, b.i.d, p.o. According to knee joint comprehensive score table (Tegner rating systems), the function comprehensive scores for all the patients pre-treatment and post-treatment knee joints were assessed.ResultsThe function comprehensive scores improved significantly after treatment in two groups(P＜0.001). The side effects in Bulleyaconitin A group decreased significantly than in diclofenac sodium group(P＜0.01).ConclusionThe intra-articular injection of SH and betamethasone accompanied with Bulleyaconitin A administration was an effective and less side-effect therapeutic measure for the treatment of knee osteoarthritis, especially for the old patients with severe knee osteoarthritis.

OBJECTIVE: To explore the distribution of cells infected by AD5-EGFP infused in different ways in the cochlea of guinea pig. METHOD: AD5-EGFP was infused into the endolymphatic system through a hole on the lateral wall of the scala media or into the extralymphatic system through the round window membrane respectively. The infected cochlear cells confirmed by expression of EGFP were examined on the whole mount or cryostat sections. RESULT: In the cochleae in which AD5-EGFP was infused into the extralymphatic system through the round window membrane, expression of EFGP could be found in the type I, IV and V fibrocyte of the stria vascularis, superlimbal cells of the spiral lip, cells in Ressenal membrane, spiral ganglion neurons in Rosenthal hole and cells lining the inner wall of scala vestibular and scala tympani, indicating that these cells were infected by adenovirus. None of the inner, outer hair or supporting cells was found to be infected in these cochleae. In the cochleae in which AD5-EGFP was infused into the endolymphatic system through a hole on the lateral wall of scala media, expression of EFGP could be found in supporting cells in the organ of Corti and lining cells of the scala media. CONCLUSION Adenovirus5 is a good and effective vector for delivering genes into cells in guinea pig's cochlea. The scope of infected cells will be very different when the vector is applied to the cochlea through different infusion ways. No cells in the endolymphatic system would be infected if the vector is infused into the extralymphatic system.

Objective To evaluate the efficacy of nerve block combined with oral administration drugs on postherpetic neuralgia (PHN). Methods 40 patients were assigned into 2 groups: group A (n=20) accepted carbamazepine, doxepin, diclofenac sodium, and vitamin B compound; while group B (n=20) combined with intercostal nerve block. The pain was assessed with visual analogue scale (VAS) before, 3 weeks and 6 months after treatment. Results The scores of VAS decreased significantly after treatment compared with the baseline in groups B (P<0.01), but only 3 weeks after treatment in group A, and it decreased more in group B than in group A (P<0.01) at any time after treatment. Conclusion Nerve block combined with oral administration drugs is effective on PHN.
