Objective:To compare the differences of lung function parameters of the patients with congenital scoliosis (CS)or idiopathic scoliosis (IS),and to clarify their influence in respiratory function.Methods:Sixty-one patients of scoliosis undergoing operation were selected.According to the cause they were divided into 25 patients with CS and 36 patients with IS.The changes of lung function parameters and the differences in the patients with scoliosis were analyzed. Results:The ages,body weights, Cobb angles of the patients in two groups had no significant differences.There were 6 cases and 12 cases of ventilation disturbance in CS and IS groups,and 15 cases and 25 cases of ventilation dysfunction.The levels of residual volume (RV),ratio of residual volume to total lung capacity (RV/TLC),RV/TLC percent predicted (RV/TLC% pred )in two groups were higher than the normal. The percentage of forced vital capacity predicted (FVC%pred)and FEV1/FVC in CS group were both lower than those in IS group (P<0.05).Some pulmonary function parameters such as vital capacity (VC%pred),FVC%pred,forced expiratory volume in one second (FEV1%pred), maximal mid expiratory flow (MMEF%pred), maximal voluntary ventilation (MVV%pred),TLC%pred and diffusion capacity for carbon monoxide of the lung (DLCO%pred)were negtively correlated with Cobb angle (r=-0.54--0.35,P<0.05)in IS group and the TLC%pred was negtively correlated with Cobb angle (r=-0.047,P<0.05)in CS group.Conclusion:Different types of scoliosis have influence in the pulmonary function of the patients.The degree of pulmonary function injury of the patients with IS is worse than that of the CS patients.The IS patients need treatment in time.

Objective:To investigate the clinical efficacy of TiRobot-assisted minimally invasive percutaneous screw fixation for pelvic fractures.Methods:The clinical data of 44 patients with pelvic fracture were retrospectively analyzed who had undergone TiRobot-assisted minimally invasive percutaneous screw fixation from May 2018 to April 2021 at Department of Orthopedic Traumatology, The First Hospital of Jilin University. There were 30 males and 14 females, aged from 11 to 78 years (average, 40.6 years). According to the Tile classification, there were 20 type C1 fractures, 23 type C2 fractures and one type C3 fracture. The time from injury to operation averaged 8.2 days (from 1 to 41 days). The minimally invasive percutaneous screw fixation was assisted by the orthopaedic TiRobot in all patients. Operation time, fluoroscopy time, reduction quality, complications and functional recovery at the final follow-up were recorded and analyzed.Results:A total of 96 screws were implanted in this cohort. The total fluoroscopy time ranged from 17 to 66 s, with an average of 17.8 s for each single screw. The operation time ranged from 50 to 355 min, averaging 179.7 min. According to the Matta criteria, the reduction quality was rated as excellent in 36 cases, as good in 5 and as fair in 3, yielding an excellent and good rate of 93.2%(41/44). All the 44 patients were followed up for 6 to 42 months (average, 20.4 months). The fracture healing time ranged from 2 to 6 months, averaging 3.3 months. The Majeed scores at the final follow-up ranged from 51 to 100 points (average, 83.7 points); there were 28 excellent, 8 good, 7 fair and one poor cases, giving an excellent to good rate of 81.8% (36/44). Follow-up found no such complications as iatrogenic neurovascular injury, incision infection, malunion, implant loosening or fracture re-displacement in all the 44 patients.Conclusion:TiRobot-assisted minimally invasive internal fixation can result in fine clinical efficacy for pelvic fractures, showing advantages of accuracy, minimal invasion and safety.

Objective To explore the suitable human albumin infusion speed in the liver cirrhosis patients with portal hypertension .Methods Fifty-eight portal hypertension patients need to infusion human albumin(50 ml,20%) were chosen and divided into the control group (n =30) and the experimental group ( n=28) by using the coin toss method .The control group received the infusion speed of 25 gtt/min for 45 min, and the experimental group received the infusion speed of 33 gtt/min for 30 min.The portal vein inside diameter (Dpv), mean blood flow velocity (Vpv), blood flow volume (Qpv) and the portal vein pressure measured by the color doppler ultrasound diagnostic instrument were compared at different times between two groups .Results At the end of the infusion, the Dpv,Vpv,Qpv and the portal vein pressure in the control group were (13.03 ± 2.01)mm,(9.40 ±2.06)cm/s,(782.29 ±313.02)ml/min and (2.747 ±0.348)kPa respectively, compared with the experimental group, and the differences were not statistically significant (t=-0.04,0.81,0.46,0.55, respectively;P>0.05).Conclusions It is feasible to input 10 g human albumin (50 ml,20%) during 30 min for the portal hypertension patients .

Objective:To investigate the clinical efficacy of robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation in the treatment of pelvic fracture.Methods:A retrospective analysis was conducted on 28 cases with pelvic fractures treated with robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation from May 2018 to November 2022. There were 19 males and 9 females, with an average age of 43.4±16.9 years (range, 14-74 years). There was 1 case of B1 type, 1 case of B2 type, 4 cases of B3 type, 10 cases of C1 type, 9 cases of C2 type and 3 cases of C3 type by Tile classification. All the cases were treated with closed reduction, LC-II external fixation for the anterior lesions and robot-assisted minimally invasive sacroiliac screw fixation for the posterior lesions. The operation time, fluoroscopy time and excellent rate of screw placement were recorded. The quality of fracture reduction was evaluated by Matta's criteria, and the clinical effect was evaluated by Majeed score.Results:All the 28 cases successfully underwent the surgery. In 11 cases the fractures were reduced by the pelvic unlocking closed reduction device while in the other 17 cases manual reduction was applied. In this cohort, 43 screws were implanted. All the screw positions reached level I by Gras grading. The average fluoroscopy time was 16.3±5.2 s (range, 9-31 s) per screw. The average operation time was 154.9±54.7 min (range, 55-226 min). According to the Matta's criteria, the reduction was rated as excellent in 19 cases, good in 7 cases, fair in 2 cases, yielding an excellent or good rate of 93% (26/28). No iatrogenic neurovascular injury was found in all the 28 patients. The average follow-up was 18.3±7.3 months (range, 4-31 months). The fractures healed at 3.6±1.1 months (range, 2-6 months) after the surgeries. At the final follow-up, the results of the Majeed scores were rated as excellent in 13 cases, good in 11 cases, fair in 3 cases and poor in 1 case, with an excellent or good rate of 86% (24/28).Conclusion:The technique of robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation used in the treatment of pelvic fracture showed good clinical results.

Artemisia argyi (A. argyi), a plant with a longstanding history as a raw material for traditional medicine and functional diets in Asia, has been used traditionally to bathe and soak feet for its disinfectant and itch-relieving properties. Despite its widespread use, scientific evidence validating the antifungal efficacy of A. argyi water extract (AAWE) against dermatophytes, particularly Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, remains limited. This study aimed to substantiate the scientific basis of the folkloric use of A. argyi by evaluating the antifungal effects and the underlying molecular mechanisms of its active subfraction against dermatophytes. The results indicated that AAWE exhibited excellent antifungal effects against the three aforementioned dermatophyte species. The subfraction AAWE6, isolated using D101 macroporous resin, emerged as the most potent subfraction. The minimum inhibitory concentrations (MICs) of AAWE6 against T. rubrum, M. gypseum, and T. mentagrophytes were 312.5, 312.5, and 625 μg·mL^-1, respectively. Transmission electron microscopy (TEM) results and assays of enzymes linked to cell wall integrity and cell membrane function indicated that AAWE6 could penetrate the external protective barrier of T. rubrum, creating breaches ("small holes"), and disrupt the internal mitochondrial structure ("granary"). Furthermore, transcriptome data, quantitative real-time PCR (RT-qPCR), and biochemical assays corroborated the severe disruption of mitochondrial function, evidenced by inhibited tricarboxylic acid (TCA) cycle and energy metabolism. Additionally, chemical characterization and molecular docking analyses identified flavonoids, primarily eupatilin (131.16 ± 4.52 mg·g^-1) and jaceosidin (4.17 ± 0.18 mg·g^-1), as the active components of AAWE6. In conclusion, the subfraction AAWE6 from A. argyi exerts antifungal effects against dermatophytes by disrupting mitochondrial morphology and function. This research validates the traditional use of A. argyi and provides scientific support for its anti-dermatophytic applications, as recognized in the Chinese patent (No. ZL202111161301.9).
