Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence， disability， mortality， and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang （DCQT） has a long history and proven efficacy in treating stroke. Clinically， DCQT is often used to treat stroke and its sequelae. However， the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research， the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage， reduce iron deposition， and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 （Nrf2）-mediated signaling pathway and p38 mitogen-activated protein kinase （MAPK） signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT， this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials， pharmacodynamic material basis， safety evaluation， and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT， 11 of which are currently confirmed absorbed components. Among them， emodin， rhein， chrysophanol， aloe-emodin， synephrine， hesperidin， naringin， magnolol， and honokiol can be used as quality markers （Q-markers） of DCQT. The mechanism of DCQT in treating stroke is complex， involving regulation of inflammatory responses， neuronal damage， oxidative stress， blood-brain barrier， brain-derived neurotrophic factor， and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Objective To evaluate the clinical efficacy of robot-assisted navigation with percutaneous lag screw treatment for Hangman's fracture.Methods We retrospectively analyzed the clinical data of 5 patients treated with robot-assisted C2 percutaneous lag screw for Hangman's fracture in our hospital from September 2021 to August 2023.Patients were positioned with moderate head-neck flexion in a Mayfield head clamp.After closed reduction with manual traction under general anesthesia,the C2 percutaneous lag screws were implanted under TINAVI orthopedic surgical robot assistance.Postoperative cervical CT scans were used to assess screw placement accuracy and fracture healing quality.Clinical efficacy was evaluated by the Odom grading system.Results All the 5 patients were operated successfully without vertebral artery injury or neurological complications.A total of 10 screws were implanted.According to the Gertzbein-Robbins standard,9 screws belonged to the grade A,and 1 belonged to the grade B,with an accuracy of 90％(9/10)and an excellent rate of 100％(10/10).The neck incision length ranged 20-30 mm(mean,27 mm).The operation time was 86-160 min(mean,112.8 min).The intraoperative blood loss was 10-50 ml(mean,30 ml).The postoperative hospitalization was5-18 d(mean,8 d).The patients were followed up for 12-34 months(mean,23.6 months).All fractures healed without screw breakage or loosening.According to the Odom grading,4 cases were excellent,and 1 case was good.Conclusion Robot-assisted navigation C2 percutaneous lag screw treatment for Hangman's fracture is accurate and minimally invasive,safe and effective.

Objective:To explore the feasibility and effect on the reconstruction of whole hand degloving injury by transfer of nerved tissue flaps in staged surgery.Methods:A retrospective study was conducted on the clinical data of 5 patients who suffered whole hand degloving injury and underwent staged reconstructive surgery with nerved tissue flaps, from December 2018 to December 2022 in the Department of Hand Surgery, Longgang Orthopaedics Hospital of Shenzhen. The patients were 4 males and 1 female, aged 22-45 years. Two of the whole-hand degloved injuries were left hands and 3 of right. Two patients had the whole-hand degloving injury combined with a fracture of distal phalangeal tuberosity, and 1 was complicated with partial rupture of the extensor tendon insertion. Areas of the whole hand degloving injury ranged from 215 cm 2 to 480 cm 2, the size of the hallux nail flaps for reconstruction of thumbs ranged from 54 cm 2 to 104 cm 2, the size of the hallux nail flaps for reconstruction of index fingers ranged from 65 cm 2 to 133 cm 2, and the size of the flaps for reconstruction of all the defects of hands ranged from 119 cm 2 to 255 cm 2. In primary surgery, the thumbs, index fingers and the first webs were reconstructed with bilateral hallux nail flaps to shape the appearance and gain the sensation function. Meanwhile, a single and large defect was created from the defects of hand by bundling up the middle, ring and little fingers together with the all the defects in both palmar and dorsal hand. Then an anterolateral thigh flap (ALTF) was used to have the created single defect wrapped together. Donor sites of the bilateral hallux nail flap were reconstructed with a lobulated ALTF from the other side or with bilateral peroneal artery perforator flaps. Donor sites of the ALTF and peroneal artery perforator flap were pulled and sutured. After the hallux nail flaps and ALTFs of the affected hands had survived and stabilised, multiple staged surgery were then carried out to firstly reconstruct the ring and little fingers, and followed by the middle and ring fingers in turns from the artificial syndactyly created in the primary surgery. In the final stage of surgery, skin of the radial side of middle and ring finger-pulps and the ulnar little finger-pulp were replaced by lateral toe flaps to reconstruct the sensations of the main sensory zones of middle, ring and little finger-pulps. Thereafter, the shape, TPD and finger extension and flexions were observed and evaluated through the postoperative follow-up, at the outpatient clinic according to the Evaluation Standard of Thumb and Finger Reconstruction Function of the Hand Surgery Society of the Chinese Medical Association. The appearance and function of the donor sites in both feet were evaluated with the Maryland foot score. Results:All flaps survived after surgery. Postoperative follow-up lasted up to 14 to 48 months after the last surgery. The appearance of fingers was satisfactory with good function. TPD of thumbs and index finger-pulps had achieved up to 6-8 mm, and 3-8 mm in the main sensory zones of middle, ring and little finger-pulps. TPD in the non-major sensory zones of middle, ring and little finger-pulps was found at 10-14 mm, which scored 13 to 14 and rated as excellent according to the Evaluation Standard of Thumb and Finger Reconstruction Function of the Hand Surgery Society of the Chinese Medical Association. Only a linear scar left in the donor site of thigh. As the appearance of the flaps on the feet was not bloated and there was no obvious abnormality in walking and running, therefore the function of feet scored up to 96 to 97 and rated excellent according to the Maryland foot score.Conclusion:A multi-staged reconstruction of a whole hand degloving injury with nerved tissue flaps not only achieves satisfactory digital and hand appearance, but also with good function. There is no obvious effect on the appearance and function of the donor sites. This surgical strategy is novel in the reconstruction of a whole hand degloving injury.

Objective:To evaluate the clinical efficacy and feasibility of the reversed fascial pedicled island flap with supercharged venous drainage in reconstruction of finger pulp defects.Methods:A retrospective study was conducted between June 2021 and October 2024 at the Department of Hand Surgery, the Eighth People's Hospital of Longgang District of Shenzhen, to evaluate 76 patients (76 digits) who had finger pulp defects and were treated by the reversed fascial pedicled island flap incorporating supercharged venous drainage. The patients were 62 males and 14 females, aged 12-66 (mean 29) years. All patients presented with pulp defects only (0.8 cm×1.2 cm - 1.9 cm×4.3 cm) without fracture or tendon injury. The surgical procedure involved a harvest of flap (1.0 cm×1.4 cm - 1.9 cm×4.5 cm in size) with 1-2 proximal veins and had the redundant veins ligated. Micro-anastomosis was performed between the veins carried by flap and the veins at recipient site. Donor sites were closed primarily or reconstructed with full-thickness skin grafting. Postoperative follow-ups were conducted through outpatient clinic and WeChat, including the evaluations of flap viability using the late-term hand flap evaluation criteria, the flap cold tolerance with the Cold Intolerance Symptom Severity (CISS) questionnaire and the digital motion with the Total Active Movement (TAM) system of the Evaluation Trial Standards of Replantation Functional of Hand Surgery of Chinese Medical Association.Results:All 76 flaps achieved complete survival without complication such as an arterial and venous compromise or an infection, except 1 flap that developed a local blister but it healed after dressing changes and removal of sutures. Over the 2 to 32 (mean 6) months of postoperative follow-up, outcomes of surgery were assessed. Sixty-seven flaps were rated as excellent and 9 as good based on the overall condition of the flap in this group. Cold tolerance was excellent for 65 flaps, good for 10 flaps and fair for 1 flap according CISS. Digital function evaluated by the TAM system showed 63 flaps of excellent, 10 of good and 3 of fair. All skin grafts at the donor sites survived well and in good appearance, without obvious depigmentation or pigmentation.Conclusion:Application of a revered fascial pedicled island flap with venous supercharging in reconstruction of finger pulp defect significantly enhances venous outflow, thereby it reduces postoperative complications such as venous occlusion, flap congestion and blistering.

Objective: To observed the effect of a curcumin-based vaginal gel combined with electroporation for the treatment of vulvovaginal candidiasis (VVC) caused by Candida albicans. Methods: Temperature-sensitive in situ gels (ISG) were prepared using poloxamers 407 and 188 as matrices. The mass ratio of poloxamer 407 and poloxamer 188 was 7:1 with a gelation temperature of approximately 29°C and gelation time of 2.5 min. Results: Electroporation increased the transmucosal permeability of the model drug, doxorubicin and improved the antifungal effects of curcumin. In vitro antifungal experiments showed that the number of fungal colonies in curcumin ISG combined with electroporation was lower than that in pure curcumin ISG. In vivo pharmacodynamic experiments showed that, compared to the model group, curcumin ISG with electroporation inhibited the growth of C. albicans, alleviated vaginal mucosal edema, and reduced the inflammatory response. Conclusion Curcumin ISG combined with electroporation has substantial potential for the efficient clinical treatment of VVC.
