The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.

Objective:To study the feasibility and efficacy of pericranial flaps for the repairs of large anterior skull base defects.Methods:The average length of the pericranial flaps needed for skull base repair was determined with computed tomography measurements in 20 adults and anatomical dissections in 5 cadaver specimen. A series of patients who underwent endoscopic skull base surgeries and subsequent reconstructions with pericranial flaps at the Department of Otolaryngology Head and Neck Surgery, Shanghai Jiao Tong University School of Medicine Affiliated Sixth People′s Hospital from 2016 to 2022 were retrospectively reviewed. There were 19 males and 6 females, aged from 11 to 59 years, including 13 cases of cerebrospinal fluid (CSF) rhinorrhea (12 traumatic) and 12 cases of sinonasal skull base tumors. Descriptive statistical methods were used.Results:The mean areas of anterior skull base, sellar, and clival defects were 16.13, 14.03 and 13.12 cm 2, respectively, and the mean pericranial flap lengths were (18.77±3.44)mm, (133.99±5.08)mm, (181.76±6.31)mm, respectively. Among sinonasal skull base neoplasms, the pathologies included olfactory neuroblastoma ( n=6), squamous cell carcinoma ( n=3), chondrosarcoma ( n=1), osteosarcoma ( n=1), and invasive schwannoma ( n=1), in whom 8 patients underwent adjuvant radiotherapy after surgery. One patient (7.7%) had acoustic neuroma-related CSF leak before radiotherapy. All 25 patients successfully underwent skull base reconstruction without complications such as CSF leak, intracranial infection, forehead wrinkles disappearance, or scalp necrosis. All flaps survived well with no CSF leaks within the follow-up period of 2-4 years. Conclusion:Pericranial flap is a safe choice for large anterior skull base defects following resection of sinonasal skull base neoplasms and complex traumatic CSF leaks when endonasal flaps are not available.

Objective To evaluate the curative effect of transcatheter arterial chemoembolization (TACE)combined with Antike in the treatment of primary liver cancer. Methods The data of 72 patients with primary liver cancer(90 lesions in total)admitted to the First Affiliated Hospital of Hebei North University from August 2016 to December 2017 were retrospectively analyzed. All patients were divided into the observa-tion group(n = 36)and the control group(n = 36)according to the therapeutic schedule. The patients in the control group(40 foci)were treated with TACE only,and the patients in the observation group(50 foci)re-ceived TCAE treatment,oral Antike capsules were taken at the same time with the frequency of three times a day,two capsules each time,and six weeks were planned for one treatment cycle. A total of four cycles were completed. All patients underwent CT enhancement scans one week before TACE treatment and six months after treatment. According to Response Evaluation Criteria in Solid Tumors,complete remission and partial remission were deemed as effectivity. The imaging data of the change of tumor size,postoperative tumor residual,tumor capsule growth and new intrahepatic metastases were analyzed and used to evaluate the curative effect of patients in the two groups. Results After 6 months of treatment,there were 39 effective lesions in the observation group and 23 in the control group. The total effective rate of the observation group was higher than that of the control group(78. 0％ vs. 57. 5％ ),and the difference was statistically significant(χ2 = 4. 357,P = 0. 037). Twenty-three neoplastic capsule lesions were detected in the observation group and 9 in the control group. The detection rate of neoplastic capsule was higher in the observation group than that in the control group(46. 0％vs. 22. 5％ ),and the difference was statistically significant(χ2 = 5. 356,P = 0. 021). There were 27 residual tumors and 5 new intrahepatic metastases in the observation group,30 residual tumors and 13 new intrahepatic metastases in the control group. The residual tumor rate and neohepatic metastasis rate in the observation group were lower than those in the control group(54. 0％ vs. 75. 0％ ;13. 9％ vs. 36. 1％ ),and the differences were statistically significant(χ2 = 4. 220,P = 0. 040;χ2 = 4. 741,P = 0. 029). Conclusion TACE combined with Antike is safe and effective in the treatment of primary liver cancer. It can improve the total clinical effi-ciency,promote the growth of tumor capsule,and reduce the recurrence rate and metastasis rate of tumor. It is worthy of clinical application.

OBJECTIVE: The role of different local flaps in small external nasal skin defect reconstruction was discussed. METHOD: Forty-two cases of the small size nasal defects (diameter < 2 cm) were repaired with local external nose flap (includes the dorsal nasal flap, nasolabial flap and bilobed flap). The clinical and follow-up data were analyzed of patients with small external nasal skin defects, who accepted different local flaps reconstruction. Dorsal nasal flap, nasolabial flaps (includes island flap, slid flap and axial flap) and bilobed flap were tailored to reconstruct different external nasal defect. Twenty-seven patients were male and fifteen patients were female, the patients' age ranged from 28 to 74 years, the median age was 61 years. Thirty-eight cases resulted from resection of skin malignant tumor and four cases were benign lesions. The diameter of defects was 1-2 cm. The defects were reconstructed by single-stage dorsal nasal flap in 7 cases. There were 30 cases of caudolateral nasal defects were reconstructed by nasolabial flap, single-stage island nasolabial flap in 7 cases, axial flap in 18 cases and slid flap in 5 cases. Superior lateral defects were reconstructed by single-stage bilobed flap in 5 cases. RESULT: All defects were repaired successfully. All tissue flaps survived and had not necrosis. There was no tumor recurrence during 3 months to 2 years follow-up. CONCLUSION The dorsal nasal flap, nasolabial flap and bilobed flap can be used safely and effectively to repair the small external nasal defect and have satisfactory curative effect.
