Objective: To observe the different effects between Mahuang (Herba Ephedra Sinicae) and Wuweizi (Fructus Schisandrae Chinensis) on the pathological changes of rats with bleomycin A(5)-induced pulmonary fibrosis. Methods: Ninety Wistar rats were randomly divided into sham operation group, model group, hydrocortisone group, Herba Ephedra Sinicae group, Fructus Schisandrae Chinensis group and Herba Ephedra Sinicae plus Fructus Schisandrae Chinensis group. There were 16 rats in each group except the sham operation group (10 rats). Pulmonary fibrosis was induced by a single intratracheal injection of bleomycin A5. Hematoxylin and eosin straining and immunohistochecical method were used after 7- and 28-day treatment to observe the pathology of lung injury, measure the inner diameter of pulmonary arterioles and the density of nuclear membrane. Results: Compared with the sham operation group at 7 and 28 d, alveolar inflammation level was significantly increased in the model group (P<0.01). Alveolar inflammation level was decreased obviously in the hydrocortisone group (P<0.05) after 7- and 28-day treatment as compared with the model group, and that in Herba Ephedra Sinicae plus Fructus Schisandrae Chinensis group was also decreased obviously (P<0.05) at 28 d. Compared with the sham operation group, nuclear density of the model group was increased, while its inner diameter was decreased (P<0.05). In the Fructus Schisandrae Chinensis group, Herba Ephedra Sinicae plus Fructus Schisandrae Chinensis group and hydrocortisone group, the nuclear density was decreased (P<0.05) as compared with the model group. Inner diameter in the Herba Ephedra Sinicae group, Herba Ephedra Sinicae plus Fructus Schisandrae Chinensis group and hydrocortisone group was higher than that in the model group (P<0.05). Microvessel density of the model group was obviously higher than that of the sham operation group (P<0.05). Compared with the model group, Herba Ephedra Sinicae plus Fructus Schisandrae Chinensis group and hydrocortisone group had lower microvessel density (P<0.05). Conclusion: Herba Ephedra Sinicae combined with Fructus Schisandrae Chinensis can restrain pulmonary artery injury. The nuclear density and microvessel density can be reduced by Fructus Schisandrae Chinensis, while Herba Ephedra Sinicae can increase the inner diameter.

BACKGROUND:Edaravone as an antioxidant protective effect on nerve cells injured by hydrogen peroxide has been confirmed, but its protective effect on oxidative damage to bone marrow stromal cells has not been reported in-depth. OBJECTIVE:To investigate the regulatory effects of edaravone on oxidative injury to bone marrow stromal cells. METHODS:Bone marrow samples were extracted from the long bone of New Zealand rabbits by the method of washing the pulp cavity, then subjected to the density gradient centrifugation and adherent screening to obtain bone marrow stromal stem cells in vitro. The bone marrow stromal cells at 3 passage were divided into five groups:blank group, treated with low-glucose Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum and 1%double antibody;dexamethasone group, treated with cellculture medium containing 1×10-7 mol/L dexamethasone;50, 100, 300 mg/L edaravone groups, cultured in cellculture medium containing 1×10-7 mol/L dexamethasone and 50, 100, 300 mg/L edaravone, respectively. After culture, MTT method and flow cytometry were used to detect the proliferative level and cellcycle of cells. RESULTS AND CONCLUSION:Compared with the control and dexamethasone groups, edaravone significantly enhanced the cellproliferation. Edaravone played a protective role in bone marrow stromal cells. When the concentration was 50 mg/L, edaravone began to play a regulatory role (P<0.05), and this effect was certainly associated with the concentration of edaravone. When the concentration was up to 100 mg/L, edaravone showed a better protective role (P<0.01). However, with increasing concentration, this protective effect was not further increased, but decreased slightly. Results indicated that high-concentration dexamethasone can induce oxidative injury to bone marrow stromal cells, and edaravone can protect the cells against this oxidative damage by antioxidant role.

Objective:To evaluate the clinical outcomes of neutral wedge osteotomy assisted by determination of the center of rotation of angulation (CORA) at the distal humerus anatomical axis for cubitus varus deformity in children.Methods:From 2016 to December 2019, 20 children with cubitus varus after supracondylar fracture of the humerus were treated at Department of Orthopeadics, Children's Hospital of Wujiang District. They were 8 boys and 12 girls, aged from 4 to 12 years (average, 7.0 years). Standard anteroposterior X-ray films of bilateral humerus were taken preoperatively for measurement of Baumann angle, proximal anatomical axis (PAA) and distal anatomical axis (DAA) of bilateral humerus to determine the CORA and the varus deformity angle. A lateral closed neutral wedge osteotomy was performed around the CORA to correct the varus deformity. All children were immobilized with elbow plaster cast after operation. Elbow flexion and extension function, postoperative scar, and body surface carrying angle were recorded. The carrying angle and Baumann angle were also measured on elbow X-ray films. Elbow function was evaluated according to the modified Flynn elbow score at 24 months after operation.Results:All patients were followed up for 24 to 36 months (mean, 29.3 months). Elbow hyperextension was close to normal in 18 cases, and 5° hyperextension existed in 2 cases. The flexion was greater than 130°, averaging 133.1° (from 130° to 138°), in 15 patients. The flexion ranged from 110° to 130° in 5 patients. The Baumann angle was 99.0°±1.0° preoperatively and 76.0°±1.0° postoperatively; the carrying angle was -14.0°±1.0° preoperatively and 13.6°±1.0° postoperatively. There were significant differences between the above items between preoperation and postoperation ( P<0.05). According to the modified Flynn elbow score at 24 months after operation, the elbow function was excellent in 16 and good in 4 cases. The varus of 40° was corrected during surgery in one child. Fixation failure or correction failure occurred in none of the children before removal of the plaster or the Kirschner wire. Conclusions:In neutral wedge osteotomy assisted by determination of the CORA at the distal humerus anatomical axis, the CORA and angulation of the distal humerus inversion can be accurately determined so that the osteotomy line and the angulation correction axis can pass through the CORA to restore the humerus alignment with no displacement of the broken ends.

Background:
Xylazole (Xyl) is a veterinary anesthetic that is structurally and functionally similar to xylazine. However, the effects of Xyl in vitro remain unknown.
Objectives:
This study aimed to investigate the anesthetic mechanism of Xyl using fetal rat nerve cells treated with Xyl.
Methods:
Fetal rat nerve cells cultured for seven days were treated with 10, 20, 30, and 40 μg/ mL Xyl for 0, 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min. Variations of amino acid neurotransmitters (AANTs), Nitric oxide-Cyclic GMP (NO-cGMP) signaling pathway, and ATPase were evaluated.
Results:
Xyl decreased the levels of cGMP and NO in nerve cells. Furthermore, Xyl affected the AANT content and Na+ -K+ -ATPase and Ca2+ -Mg2+ -ATPase activity in nerve cells. These findings suggested that Xyl inhibited the NO-cGMP signaling pathway in nerve cells in vitro.
Conclusions
This study provided new evidence that the anesthetic and analgesic effects of Xyl are related to the inhibition of the NO-cGMP signaling pathway.

AIM:To investigate the visual quality and stereopsis after the implantation of PanOptix trifocal intraocular lens(TFNT00).METHODS: A prospective clinical study was conducted. A total of 36 cataract patients(50 eyes)who underwent phacoemulsification combined with TFNT00 implantation in Jinan Mingshui Eye Hospital from November 2022 to April 2024 were selected. They were followed up until 3 mo after the operation. The uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA), uncorrected near visual acuity(UCNVA), objective scatter index(OSI), modulation transfer function cut off(MTF-cut-off), Strehl ratio(SR)and 100%, 20%, 9% contrast visual acuity(CVA)were observed. The binoptometer was used to collect the patients' far and near stereopsis acuities. The defocus curve was drawn after the operation; the Chinese version of the VF-14 Visual Function Index Scale was used to evaluate the visual quality and satisfaction after the operation.RESULTS: There were statistically significant differences in the UCDVA, UCIVA and UCNVA of the patients at different time after the operation(all P<0.05). The transition of the defocus curve was gentle between +0.5--3.0 D after the operation. The OSI value at 3 mo postoperatively after the operation was significantly lower than that before the operation(P<0.01), and the MTF-cut-off, SR, 100% CVA, 20% CVA and 9% CVA were significantly improved than those before operation(all P<0.01). The far and near stereopsis acuities of 34 patients were abnormal before the operation. The far stereopsis acuities of the patients who underwent bilateral eye surgeries were all normal after the operation, and the near stereopsis acuity of 12 patients was normal. Among the patients who underwent unilateral eye surgeries, the far stereopsis acuities of 13 patients were normal, and the near stereopsis acuities of 11 patients were normal. The far and near stereopsis acuities of the patients who underwent bilateral eye surgeries were significantly better than those patients who underwent unilateral eye surgeries.CONCLUSION: The PanOptix trifocal intraocular lens can provide patients with good full-range visual acuity. The stereopsis of the patients with bilateral implants is better than that of the patients with unilateral implants. The overall visual quality and satisfaction of the patients after the operation are relatively high.
