ObjectiveThis study focused on the marketed Chinese patent medicines for the treatment of Functional Diarrhea （FDr） in China and their prescription characteristics， in order to provide support for the clinical application and research and development of anti-FDr Chinese patent medicines. MethodsCollect the information of Chinese patent medicines that have been marketed to treat FDr， use Microsoft Excel 2021 software to conduct preliminary data collation and statistical analysis， and use the ancient and modern medical record cloud platform （V2.3.9） to analyze the standardized Chinese patent medicine prescriptions from the aspects of drug nature and taste， medication characteristics and prescription rules. Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective:To evaluate the differences in total effectiveness, Visual Analogue Scale (VAS) scores, and Cox Menstrual Symptom Scale (CMSS) scores among four non-invasive Traditional Chinese Medicine (TCM) techniques: moxibustion, massage therapy, acupoint application, and auricular acupressure, for the care of primary dysmenorrhea (PD) using network Meta-analysis, providing evidence-based guidance for clinical decision-making.Methods:Randomized controlled trials (RCTs) involving the four non-invasive TCM techniques for PD care were retrieved from databases including China National Knowledge Infrastructure, VIP, Wanfang, SinoMed, PubMed, Embase, Web of Science, and Cochrane Library up to November 30, 2023. Network Meta-analysis was conducted using RevMan 5.4 and Stata 17.0.Results:A total of 83 studies involving 8 370 PD patients were included. The network Meta-analysis showed that all four TCM techniques were superior to control measures in terms of total effectiveness and reducing VAS scores. Moxibustion, acupoint application, and auricular acupressure were also superior in reducing CMSS scores. Ranking of the effects of different interventions: total effectiveness: auricular acupressure > moxibustion > acupoint application > massage therapy > acupuncture > Chinese patent medicine > Western medicine > blank control > placebo treatment; VAS scores: moxibustion > auricular acupressure > acupoint application > acupuncture > placebo treatment > massage therapy > Western medicine > Chinese patent medicine > blank control; CMSS scores: auricular acupressure > moxibustion > acupuncture > placebo treatment > acupoint application > Western medicine > blank control.Conclusions:The four non-invasive TCM techniques have significant advantages in PD care, with auricular acupressure and moxibustion being the preferred choices for clinical care.

This paper reported a case of simultaneous twin pregnancy and successful delivery in each horn of uterus didelphys. The patient had a history of adverse pregnancies and was diagnosed with a uterus didelphys with double cervix through hysteroscopy, although the uterine cavity morphology was normal. This pregnancy was conceived naturally, with the last menstrual period on December 21, 2023. The patient underwent regular prenatal check-ups at Xi'an People's Hospital (Xi'an Fourth Hospital). Early pregnancy ultrasound confirmed simultaneous twin pregnancy in each horn of uterus didelphys. Multiple ultrasounds showed no fetal growth restriction or other abnormalities. At 37 weeks of gestation, the patient experienced chest tightness and shortness of breath due to polyhydramnios, and one fetus was in the cephalic position while the other was in the breech position, posing a high risk for vaginal delivery. Therefore, an elective cesarean section was performed at 37 weeks and one day of gestation, delivering a male infant weighing 3 260 g and a female infant weighing 2 400 g. The 1-,5-, and 10-minute Apgar scores were all 10 points, with favorable maternal and neonatal outcomes.

Objective To investigate the value of serum ribosomal biogenesis factor nucleolar protein53(NOP53)mRNA and fibronectin type Ⅲ domain containing 1(FNDC1)mRNA in evaluating the efficacy of neoadjuvant chemoradiotherapy(NACRT)in patients with locally advanced rectal cancer.Methods A total of 140 patients with locally advanced rectal cancer who received NACRT treatment in Yulin Hospital the First Affiliated Hospital of Xi'an Jiaotong University from January 2020 to January 2023 were selected as the study group.According to the efficacy of NACRT treatment,they were divided into good response group(99 cases)and poor response group(41 cases).At the same time,70 healthy people were selected as control group.Real-time fluorescence quantitative PCR was used to detect serum NOP53 mRNA and FNDC1 mRNA levels in the two groups.Logistic regression analysis was used to analyze the factors affecting the efficacy of NACRT.The value of serum NOP53 mRNA and FNDC1 mRNA in evaluating the efficacy of NACRT for rectal cancer was analyzed by receiver operating characteristic analysis.Results The expression of serum NOP53 mRNA(3.21±0.36)and FNDC1 mRNA(2.73±0.34)in the study group was higher than that in the control group(0.61±0.17,0.72±0.18),and the differences were statistically significant(t=57.267,46.287,all P<0.001).The expression of serum NOP53 mRNA(4.08±0.43,4.10±0.40)and FNDC1 mRNA(3.62±0.39,3.40±0.39)in patients with T stage T4 and N stage N1+N2 rectal cancer was higher than that in patients with T stage T3(2.52±0.30,2.02±0.29)and N stage N0(2.21±0.31,1.02±0.30),and the differences were statistically significant(t=25.241～40.106,all P<0.001).The proportion of T stage T4(73.17%),N stage N1+N2(75.61%),serum NOP53 mRNA(5.56±0.39)and FNDC1 mRNA(4.42±0.38)in the poor response group were higher than those in the good response group(32.32%,43.43%,2.24±0.31,2.03±0.29),and the differences were statistically significant(t=12.045～53.337,all P<0.001).T stage T4,N stage N1+N2,high serum NOP53 mRNA,high serum FNDC1 mRNA were risk factors affecting the efficacy of NACRT for rectal cancer(Wald χ2=9.463～15.589,all P<0.001).The AUC of serum NOP53 mRNA combined with FNDC1 mRNA in evaluating the efficacy of NACRT for rectal cancer higher than predicted by serum NOP53 mRNA and FNDC1 mRNA alone,and the differences were statistically significant(Z=4.645,4.321,all P<0.001).Conclusion The levels of serum NOP53 mRNA and FNDC1 mRNA in patients with locally advanced rectal cancer are increased,which are related to the poor clinicopathological features of patients.Combined with serum NOP53 mRNA,FNDC1 mRNA can effectively predict the clinical efficacy of NACRT in patients with rectal cancer.

Objective:To explore the clinical effects of sequential treatment of extensive skin and soft tissue injuries of the lower leg accompanied by large segmental tibial defects by free transplantation of anterolateral thigh perforator flap combined with bone transport.Methods:This study was a retrospective observational study. From April 2020 to January 2024, 8 patients with extensive skin and soft tissue injuries of the lower leg accompanied by large segmental tibial defects who met the inclusion criteria were admitted to Beijing Dawanglu Emergency Rescue Hospital. Among them, there were 6 males and 2 females, aged 17 to 58 years. After debridement, the area was 17 cm×8 cm to 30 cm×12 cm, and the length of tibial defect was 9 to 12 cm. Stage Ⅰ surgery was performed by free transplantation of anterolateral thigh perforator flap to repair the extensive skin and soft tissue injuries of the lower leg and using autologous skin graft from the thigh to repair the remaining wound. Stage Ⅱ surgery was performed after wound healing, the external fixation bracket was removed and replaced with an Orthofix unilateral external fixation lengthening frame (hereinafter referred to as external fixation lengthening frame) to transport the proximal tibial osteotomy for repairing the large segmental bone defects. The intraoperative arteriovenous anastomosis and the blood supply of the flap during stage Ⅰ surgery were documented, along with the survival status of the flap/skin graft in the donor and recipient areas postoperatively, and the wound healing time in the recipient area. The time required for bone transport completion, the duration of external fixation retention, and the occurrence of complications during this period were recorded after stage Ⅱ surgery. During follow-up, the occurrence of adverse events in the recipient area was recorded. At the final follow-up, fracture healing of the affected limb was evaluated according to the Paley score, and limb function was observed.Results:In 2 patients, the descending branch of the lateral circumflex femoral artery and the accompanying vein were end-to-end anastomosed with the proximal anterior tibial or posterior tibial artery and vein for antegrade blood supply and antegrade reflux; in 2 patients, the descending branch of the lateral circumflex femoral artery was end-to-end anastomosed with the distal anterior tibial artery for retrograde blood supply, and the accompanying vein of the descending branch of the lateral circumflex femoral artery was end-to-end anastomosed with the proximal anterior tibial vein for antegrade reflux; in 3 patients, the descending branch of the lateral circumflex femoral artery was end-to-end anastomosed with the distal posterior tibial artery for retrograde blood supply, and the accompanying vein of the descending branch of the lateral circumflex femoral artery was end-to-end anastomosed with the distal posterior tibial vein for retrograde reflux; one patient underwent repair of the injury in the affected lower leg using a free cross-leg vascular pedicle flap from the healthy limb. The flaps/skin grafts in the donor and recipient areas of all 8 patients survived, and the wound healing time in recipient area was 14 to 30 days. The bone transport duration of the patients in this group was 93 to 125 days, and the external fixation lengthening frame was continuously retained for 7 to 14 months after the bone transport was stopped; during the bone transport period, 1 patient had pin tract infection, which was controlled after dressing change and enhanced nursing. During the follow-up, there was no ulceration of the wound surface in recipient area, and no osteomyelitis or fracture developed in the affected limb. At the last follow-up, the bone healing evaluation was all excellent; the walking posture and function of the affected limb were basically normal.Conclusions:The application of free transplantation of anterolateral thigh perforator flap combined with bone transport in the sequential treatment of extensive skin and soft tissue injuries of the lower leg accompanied by large segmental tibial defecst can achieve wound healing and functional reconstruction of bone defects, and has great clinical application value.
