Objective:To explore the differences in clinical efficacy between Co-Cr-Mo guided multidirectional sliding growing rod technology (CMSG) and traditional growing rod in the treatment of neurofibromatosis type 1 dysplastic early-onset scoliosis.Methods:A retrospective analysis was conducted on the data of 20 patients with neurofibromatosis type 1 dysplastic early-onset scoliosis who underwent surgical treatment in the Scoliosis Department of Zhengzhou Orthopaedic Hospital Affiliated to Henan University from January 2010 to July 2022. There were 10 patients in the traditional rod group (treated with traditional growing rod surgery) and 10 patients in the CMSG group (treated with CMSG technology). All patients were ≤10 years old and had a Cobb angle ≥45°. The number of surgeries and the occurrence of complications were recorded. The Cobb angle of the main scoliotic curve, the Cobb angle of kyphosis from T 5 to T 12, and the height from T 1 to S 1 were measured from the imaging data to evaluate the correction of deformity and spinal growth. Results:There were no significant differences in age, gender, follow - up time, preoperative Cobb angle, and preoperative Cobb angle of kyphosis from T 5-T 12 between the CMSG group and the TGR group ( P>0.05). The number of surgeries 1.3±0.67 and the total medical cost 91, 100±34, 700 yuan in the CMSG group were lower than those in the TGR group (5.3±1.77 times and 155, 800±45, 900 yuan], and the differences were statistically significant ( t=6.687, P<0.001; t=3.558, P=0.002). The Cobb angles of the main curve before surgery, after the first surgery, and at the last follow - up in the CMSG group were 69.7°±17.8°, 19.8°±9.7°, and 24.4°±9.0° respectively, while those in the TGR group were 62.0°±11.1°, 32.1°±11.4°, and 33.3°±11.6° respectively. The differences in Cobb angles after the first surgery and at the last follow-up between the two groups were statistically significant ( t=2.633, P=0.017; t=2.313, P=0.033). The Cobb angles of kyphosis from T 5 to T 12 before surgery, after the first surgery, and at the last follow - up in the CMSG group were 40.0°±24.2°, 21.0°±6.0°, and 33.6°±9.3° respectively, while those in the TGR group were 31.3°±14.5°, 26.3°±10.5°, and 32.3°±17.2° respectively. There were no significant differences in the Cobb angles of kyphosis from T 5 to T 12 after the first surgery and at the last follow-up between the two groups ( t=1.383, P=0.184; t=0.243, P=0.811). The heights from T 1 to S 1 before surgery, after the first surgery, and at the last follow-up in the CMSG group were 30.5±3.4 cm, 33.7±3.3 cm, and 37.9±4.8 cm respectively, with an annual increase of 1.18±0.39 cm. The heights from T 1 to S 1 in the TGR group were 29.1±3.0 cm, 31.4±2.9 cm, and 36.3±3.5 cm respectively, with an annual increase of 1.25±0.23 cm. There was no significant difference in the annual growth height of T 1-S 1 between the two groups ( t=1.367, P=0.189). During the follow-up period, 3 patients in the CMSG group had 3 complications: 1 case of coronal plane trunk decompensation, 1 case of rod fracture, and 1 case of distal junctional kyphosis. In the TGR group, 7 patients had 8 complications: 2 cases of wound rupture, 3 cases of screw loosening, 1 case of distal addition phenomenon, 1 case of proximal addition phenomenon, and 1 case of rod fracture. Conclusion:The Co-Cr-Mo guided multidirectional sliding growing rod technique is safe and effective in treating type 1 neurofibromatosis with malnutrition type early-onset scoliosis. It can effectively control the progression of spinal deformities,preserve the growth ability of the spine, and have a low overall incidence of complications.

Objective:To evaluate the effect of ciprofol on intraoperative hypotension in patients undergoing bronchoscopy procedures.Methods:In this randomized controlled study, 112 adult patients of either sex, aged 18-64 yr, with a body mass index of 19.8-28.3 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with estimated operation time of ≥1 h, undergoing elective bronchoscopy procedures, were assigned to one of two groups ( n=56 each) using a random number table method: ciprofol group (C group) and propofol group (P group). All the patients received total intravenous anesthesia. The induction dose of ciprofol was 0.1-0.3 mg/kg, and the maintenance dose was 0.4-1.2 mg·kg -1·h -1 in group C. The induction dose of propofol was 1-3 mg/kg, and the maintenance dose was 4-12 mg·kg -1·h -1 in group P. The primary outcome was the incidence of intraoperative hypotension, and the secondary outcomes were the time of emergence from anesthesia, sleep quality, patients′ and surgeons′ satisfaction with anesthesia, and the incidence of complications within 30 days after surgery. Results:Compared with group P, the incidence of intraoperative hypotension was significantly decreased, and the time of emergence from anesthesia was shortened in group C ( P<0.05). There was no statistically significant difference in secondary outcomes between the two groups ( P>0.05). Conclusions:Ciprofol is superior to propofol in reducing the risk of intraoperative hypotension and facilitates a more rapid emergence from anesthesia in patients undergoing bronchoscopy procedures.

Hepatitis B virus (HBV) infection is a global public health problem, which mainly causes a series of liver diseases such as hepatitis, liver cirrhosis, and hepatocellular carcinoma. However, recent years' studies have shown that the occurrence of multiple extrahepatic malignancies may also be associated with HBV infection. For example, studies have found that patients with HBV infection have a significantly higher risk of developing digestive system tumors such as gastric cancer, colorectal cancer, and pancreatic cancer, as well as an increased risk of other systemic malignancies such as lymphoma, leukemia, and oral cancer. Although the liver is the primary target organ of HBV, the presence of the virus in non-hepatic tissues suggests that it may play an impact in the development of other extrahepatic tumors. The findings of these associations have important implications for public health policies and cancer prevention strategies, emphasizing the need for multisystem tumor screening in patients with HBV infection.

Objective:To explore the effect of free transplantation of composite tissue flap from the anterior lateral aspect of the femur in repairing head skin defects with artificial dural exposure infection.Methods:A retrospective study was conducted on 13 patients admitted to the First Affiliated Hospital of Air Force Military Medical University from April 2018 to August 2020 with craniotomy complications, including craniotomy skin and soft tissue defects combined with artificial dural exposure and infection. After preoperative anti infection treatment, the neurosurgery department participated in debridement and removed the artificial dura mater as much as possible during the operation. A composite tissue flap carrying the fascia lata was designed for the anterior lateral aspect of the thigh, and the flap artery and vein were anastomosed with the superficial temporal artery and superficial temporal vein/middle temporal vein respectively. The defect of the dura mater was repaired with the fascia lata with blood supply. The flap was used to seal the wound, and the donor site was directly sutured or transplanted with autologous medium thick skin graft. The postoperative blood supply and survival of the flap, the presence of cerebrospinal fluid leakage, and the healing of the donor site were observed; The observation of dural integrity and postoperative effects of skull reconstruction using cranial magnetic resonance imaging was followed up.Results:Among the 13 patients in this group, 11 patients had their artificial dura mater completely removed, while 2 patients were not completely removed due to severe adhesion. Among them, 1 patient had a residual area of 0.8 cm×1 cm, and the other had 3 residual areas, with a maximum area of 0.5 cm×0.7 cm; All transplanted skin flaps survived, with 12 cases achieving primary healing and 1 case of partial wound rupture after suture removal, which healed after conservative dressing change; All patients had no cerebrospinal fluid leakage; There was one case of partial necrosis of the graft in the donor site, which healed after supplementing the graft; Thirteen patients underwent cranial magnetic resonance imaging at 3-6 months postoperatively, all of which showed intact dura mater; Among them, 8 patients have completed skull reconstruction surgery, and all of them have healed well after reconstruction, with a good appearance of the surgical area.Conclusions:For wounds with head skin defects and exposed artificial dura mater infection, free transplantation of the anterior lateral composite tissue flap carrying the fascia lata can effectively cover the wound and repair the dura mater defect, achieve good function and appearance, and create favorable conditions for later skull reconstruction.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.
