Objective:To compare the efficacy of intraluminal microwave ablation with radiofrequency ablation in the treatment of varicose veins of the lower extremities.Methods:The clinical data of 520 patients (522 affected limbs) who underwent lower extremity varicose vein surgery at the Department of Vascular Surgery of the First Affiliated Hospital of Anhui Medical University from Jun 2021 to Sep 2022 were collected. Patients were divided into endovenous microwave ablation group (EMWA group, n = 201) and radiofrequency ablation group (RFA group, n = 321). Follow-up was performed at 1 week, 1 , 6 and 12 months after surgery. The primary efficacy endpoint was the occlusion rate of the treated segment vein, the primary safety endpoint was the incidence of surgery-related and/or device-related complications, and the secondary endpoints were the venous clinical severity score (VCSS) and chronic venous insufficiency quality of life questionnaire (CIVIQ) scores at follow-up. Results:The technique success rate and the occlusion rate of the affected segment vein was 100% in both groups evaluated one week after surgery; Six and 12 months after surgery, the occlusion rate in the RFA group was 98.9%, and that in the EMWA group was 99.3% and respectively 97.8%, 97.2% ,without statically significant difference.During the follow-up period, there were no cases of reoperation due to vein recanalization. no serious events such as deep vein thrombosis, pulmonary embolism or death occurred in either group. The incidence of adverse events (induration, ecchymosis, skin burn, incision infection, limb numbness, hematoma, thrombotic superficial phlebitis, endovenous heat induced thrombosis, etc.) in both groups was compared, and the difference was not statistically significant. VCSS and CIVIQ scores improved significantly in both groups at 1 ,6 and 12 months after treatment, and the difference was statistically significant(all P < 0.01). Conclusion:EMWA and RFA have the advantages of simple operation, good clinical efficacy and high degree of improvement in quality of life.

The experiment was aimed to investigate the difference of plasma concentration and pharmacokinetic parameters between liposome and aqueous solution of toatal ginsenoside of ginseng stems and leaves in rats, such as ginsenosides Rg₁, Re, Rf, Rb₁, Rg₂, Rc, Rb₂, Rb₃, Rd. After intravenous injection of liposome and aqueous solution in rats, the blood was taken from the femoral vein to detect the plasma concentration of the above 9 ginsenoside monomers in different time points by using HPLC. The concentration-time curve was obtained and 3p97 pharmacokinetic software was used to get the pharmacokinetic parameters. After the intravenous injection of ginsenosides to rats, nine ginsenosides were detected in plasma. In general, among these ginsenosides, the peak time of the aqueous solution was between 0.05 to 0.083 3 h, and the serum concentration peak of liposome usually appeared after 0.5 h. After software fitting, the aqueous solution of ginsenoside monomers Rg₁, Re, Rf, Rg₂, Rc, Rd, Rb₃ was two-compartment model, and the liposomes were one-compartment model; aqueous solution and liposome of ginsenoside monomers Rb₁ were three-compartment model; aqueous solution of ginsenoside monomers Rb₂ was three-compartment model, and its liposome was one-compartment model. Area under the drug time curve (AUC) of these 9 kinds of saponin liposomes was larger than that of aqueous solution, and the retention time of the liposomes was longer than that of the aqueous solution; the removal rate was slower than that of the aqueous solution, and the half-life was longer than that of the water solution. The results from the experiment showed that by intravenous administration, the pharmacokinetic parameters of two formulations were significantly different from each other; the liposomes could not only remain the drug for a longer time in vivo, but also reduce the elimination rate and increase the treatment efficacy. As compared with the traditional dosage forms, the total ginsenoside of ginseng stems and leaves can improve the sustained release of the drug, which is of great significance for the research and development of new dosage forms of ginsenosides in the future.

OBJECTIVETo discuss the clinical characteristics of primary hyperparathyroidism (PHPT) with kidney stones.

METHODSThe clinical data of 23 cases undergoing diagnostic evaluation and surgery for PHPT combined with kidney stones between January 2004 and February 2012 was retrospectively analyzed. The 23 cases had undergone preoperative parathyroid neck color ultrasound, CT or (99)mTc-methoxy isobutyl isonitrile ((99)mTc-MIBI) diagnosis. The surgical treatment included parathyroid disease and kidney stones. The intravenous calcium, phosphorus and serum intact parathyroid hormone (iPTH) levels, 24 hours urinary calcium concentrations were measured 3 days before and 7 days after surgery.

RESULTSThere were 8 male and 15 female patients. The stone diameter were (3.2 ± 0.7) cm (range 2.1-4.0 cm). All patients did both parathyroid surgery and kidney surgery. The statistical discrepancy of serum calcium (there were (3.31 ± 0.39) mmol/L before surgery and (2.12 ± 0.18) mmol/L at 7 days after surgery, t = 11.26), serum phosphorus ((0.70 ± 0.09) and (1.21 ± 0.21) mmol/L in before and after surgery respectively, t = 10.53), iPTH (there were (28.8 ± 10.0) pmol/L before surgery and (3.6 ± 2.6) pmol/L after surgery, t = 12.83) and 24-hours urine calcium (there were (7.2 ± 3.1) mmol/d before surgery and (3.6 ± 2.5) mmol/d after surgery, t = 8.81) before and after the operation was significant (all P < 0.01). PTH concentration with serum calcium concentration correlation coefficient was r = 0.59 (P < 0.01). Eighteen patients (78.3%) had solitary parathyroid adenomas, two patients (8.7%) had multiple parathyroid adenomas, and three patients (13.0%) had multiglandular hyperplasia confirmed at surgery and histology. During follow-up, 8 patients had stone recurrence and 3 patients were did operation again to deal with renal stone within 2 years. Among them, 7 cases were normal, 1 case of parathyroid adenomas recurrence and reoperation.

CONCLUSIONSThe parathyroid operation may reduce the calculus recurrence remarkably. Early diagnosis and treatment of primary hyperparathyroidism is helpful to reduce the calculus recurrence and preserve the renal function.
