Objective:To observe the improvement of facial weakness in patients with peripheral facial palsy treated with needling the muscle regions of meridians plus Da Qin Jiao Tang[decoction of Qin Jiao(Radix Gentianae Macrophyllae)],and the effects on facial paralysis injury function and mimetic muscle atrophy and motor conduction. Methods:A total of 120 patients with peripheral facial palsy were randomized into a Chinese medication group and an acupuncture medication combined group by the random number table method,with 60 cases in each group.The Chinese medication group was treated with Da Qin Jiao Tang,and the acupuncture medication combined group was treated with needling the muscle regions of meridians based on oral Da Qin Jiao Tang.After treatment,the clinical efficacy was compared between the two groups.The changes in the facial symptom score,facial muscle thickness,facial muscle strength,facial nerve function,and facial disability index were observed. Results:The total effective rate in the acupuncture medication combined group was 98.3%,which was higher than 85.0%in the Chinese medication group(P<0.05).Each facial symptom score in the acupuncture medication combined group was lower than that in the Chinese medication group(P<0.05).The muscle thickness of the depressor anguli oris,frontalis,and depressor labii inferioris in the acupuncture medication combined group was thicker than that in the Chinese medication group(P<0.05).The scores of physical function and social/behavioral function in the acupuncture medication combined group were lower than those in the Chinese medication group(P<0.05),while the scores of manual muscle test(MMT)and Sunnybrook facial nerve were higher than those in the Chinese medication group(P<0.05).The facial nerve motor latency of the upper lip quadrate muscle,frontalis,and orbicularis oculi in the acupuncture medication combined group was lower than that in the Chinese medication group(P<0.05),while the M-wave amplitude was higher than that in the Chinese medication group(P<0.05). Conclusion:Needling the muscle regions of meridians plus Da Qin Jiao Tang can improve facial muscle strength,mimetic muscle atrophy,facial paralysis function injury,and facial nerve motor conduction in the treatment of peripheral facial palsy and enhance clinical efficacy.

Objective:To systematically review the predictive model for de novo stress urinary incontinence (de novo SUI) after pelvic organ prolapse (POP) surgery, with the aim of providing reference for preventing the occurrence of de novo SUI.Methods:Literature on the prediction model of de novo SUI after POP surgery was electronically retrieved in PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, WanFang, and VIP. The search period was from the establishment of the database to December 31, 2023, and the language was limited to Chinese and English. Two researchers independently screened literature, extracted data, and used the prediction model risk of bias assessment tool (PROBAST) to evaluate the quality of the models.Results:A total of 13 articles were included, including 13 de novo SUI risk prediction models. One literature was a prospective study, one literature was a secondary analysis of data, and the rest were retrospective studies. The area under the receiver operating characteristic curve in nine models ranged from 0.595 to 0.842, and the C-index of three models ranged from 0.710 to 0.738. Five models were not validated or only internally validated after construction. Six models were validated in one external population. The predictive performance of one model was validated in six external populations. The overall applicability of the 13 prediction models was good, but there was a certain risk of bias in all of them. Conclusions:There is a significant difference in the predictive performance of the de novo SUI risk prediction model after POP surgery, and the number is relatively small, indicating that it is still in the development stage. Future research should continuously optimize existing models and conduct external validation, and construct predictive models suitable for postoperative de novo SUI in POP patients in China.

Objective:To explore the clinical effects of parallel combined flow-through perforator flaps in the treatment of circular hot crush injuries in limbs with blood supply disorder.Methods:The study was a retrospective observational study. From April 2016 to December 2022, 4 cases with circular hot crush injuries in limbs with blood supply disorder were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 3 males and 1 female, aged from 24 to 48 years. Among them, 2 cases were injured in the calf and 2 cases were injured in the forearm. After emergency debridement, the area of skin and soft tissue defects was from 20 cm×20 cm to 44 cm×20 cm. The patients had defects in tibialis anterior and posterior tibial arteries with a length of 13 to 18 cm, and in ulnar and radial arteries with a length of 9 to 12 cm. Flaps were designed and cut, including a flow-through anterolateral thigh perforator flap with area of 20 cm×9 cm to 24 cm×21 cm carrying the descending branch of the lateral circumflex femoral artery and the accompanying veins of 8 to 18 cm in length; and a flow-through posterior tibial artery perforator flap with area of 21 cm×13 cm and 20 cm×14 cm carrying the posterior tibial artery, the accompanying veins with a length of 14 and 17 cm respectively, and the great saphenous vein with a length of 22 and 21 cm. The circular hot crush injury wounds in the calf with blood supply disorder were repaired by a parallel combination of flow-through posterior tibial artery perforator flap and flow-through anterolateral thigh perforator flap, and the circular hot crush injury wounds in the forearm with blood supply disorder were repaired by a parallel combination of bilateral flow-through anterolateral thigh perforator flap, and the injured main vessels were reconstructed. The donor site wounds of flap were closed directly or treated with split-thickness skin grafts from abdomen. After surgery, the blood supply and survival of the flap and distal affected limb, the healing of wounds in the donor and recipient sites, the survival of the skin graft in the flap donor site were observed. During follow-up, the condition of flaps, the appearance, blood supply, and function of affected limbs were observed. At the last follow-up, the foot and ankle functions were evaluated according to the scoring standards of American Orthopedic Foot and Ankle Association, and the wrist and hand function was evaluated according to the trial standard of replantation of amputated upper limb function assessment of the Hand Surgery of Chinese Medical Association. Results:The flaps and distal affected limbs of 4 patients had good blood circulation and successfully survived after surgery. The wounds of 3 cases successfully healed, while one patient with circular hot crush injury in the forearm experienced exudation in the recipient site in the later stage, and the wound healed after re-expansion and suturing. The donor site wounds healed smoothly, and the skin grafts successfully survived. During follow-up of 12 to 24 months after surgery, the flaps were slightly swollen, the limbs had good appearance, normal blood circulation, and fine functional recovery. At the last follow-up, the foot and ankle function of 2 patients with circular hot crush injuries in the calf was evaluated as good in 1 case and commonly in 1 case; the wrist and hand function of 2 patients with circular hot crush injuries in the forearm was evaluated as excellent in 1 case and good in 1 case.Conclusions:The parallel combined flow-through perforator flap can reconstruct the damaged main blood vessels and repair the wound at the same time. It can not only effectively save the limb, but also restore part of the function of the affected limb. It is one of the effective methods to treat the circular hot crush injuries in limbs with blood supply disorder.
