Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

The data of patients of both sexes, aged ≥ 18 yr, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, underwent thoracoscopic lung surgery under general anesthesia from January 2017 to December 2017, were retrospectively collected.The patients were divided into 2 groups according to whether they received thoracic paravertebral block (PVB) before operation: general anesthesia group (group G) and thoracic PVB combined with general anesthesia group (GP group). T 3/T 4 and T 6/T 7 double point thoracic PVB was performed under ultrasound guidance before anesthesia induction in GP group.Anesthesia was induced with sufentanil, propofol/etomidate and cisatracurium and maintained with propofol, remifentanil, cisatracurium and dexmedetomidine during operation.According to whether sufentanil was added before skin incision, patients received thoracic PVB combined with general anesthesia were divided into 2 subgroups: increment of sufentanil group and non-increment of sufentanil group, and a 1∶1 propensity score matching was performed in two groups.The usage of vasopressor drugs, amount of opioids consumed, volume of fluid infused, urine volume, blood loss and operation time were recorded.Compared with group G, the intraoperative urine volume, volume of fluid infused, and requirement for vasopressor drugs after skin incision were increased, and the intraoperative consumption of remifentanil was reduced in group GP ( P<0.05). Before matching, compared with non-increment of sufentanil group, the consumption of sufentanil at induction, intraoperative blood loss, volume of fluid infused and urine volume were significantly increased, and the operation time was prolonged in increment of sufentanil group ( P<0.05). After matching, compared with non-increment of sufentanil group, the requirement for vasopressor drugs was significantly increased in increment of sufentanil group ( P<0.05). In conclusion, thoracic PVB can increase the incidence of intraoperative hypotension in the patients undergoing thoracoscopic lung surgery under general anesthesia, and the reason may be related to the thoracic PVB-induced direct inhibition of sympathetic nerves and to opioids usage.

BACKGROUNDQuantitative T2 mapping has been a widely used method for the evaluation of pathological cartilage properties, and the histological assessment system of osteoarthritis in the rabbit has been published recently. The aim of the study was to investigate the effectiveness of quantitative T2 mapping evaluation for articular cartilage lesions of a rabbit model of anterior cruciate ligament transection (ACLT) osteoarthritis.

METHODSTwenty New Zealand White (NZW) rabbits were divided into ACLT surgical group and sham operated group equally. The anterior cruciate ligaments of the rabbits in ACLT group were transected, while the joints were closed intactly in sham operated group. Magnetic resonance (MR) examinations were performed on 3.0T MR unit at week 0, week 6, and week 12. T2 values were computed on GE ADW4.3 workstation. All rabbits were killed at week 13, and left knees were stained with Haematoxylin and Eosin. Semiquantitative histological grading was obtained according to the osteoarthritis cartilage histopathology assessment system. Computerized image analysis was performed to quantitate the immunostained collagen type II.

RESULTSThe average MR T2 value of whole left knee cartilage in ACLT surgical group ((29.05±12.01) ms) was significantly higher than that in sham operated group ((24.52±7.97) ms) (P=0.024) at week 6. The average T2 value increased to (32.18±12.79) ms in ACLT group at week 12, but remained near the baseline level ((27.66±8.08) ms) in the sham operated group (P=0.03). The cartilage lesion level of left knee in ACLT group was significantly increased at week 6 (P=0.005) and week 12 (P<0.001). T2 values had positive correlation with histological grading scores, but inverse correlation with optical densities (OD) of type II collagen.

CONCLUSIONThis study demonstrated the reliability and practicability of quantitative T2 mapping for the cartilage injury of rabbit ACLT osteoarthritis model.

This article describes the preparation of the N-tert-butyl-alpha-phenylnitrone (PBN) liposomes and their related characteristics. The PBN liposomes were prepared by film dispersion-supersonic method and the formula of liposomes was optimized by orthogonal uniform design. RP-HPLC was used to qualify the amount of PBN that entered into the hepatoma cells. Necrosis rate was also investigated by fluorescence activated cell sorter (FACS) after PBN liposomes transfection. Result showed that the mean particle size, entrapment efficiency, and polydispersity of the resulting PBN-liposome were 137.5 nm, 71.52% and 0.286, respectively. PBN liposomes can enter into the tumor cell stably and they have higher affinity to hepatoma cell compared with free PBN resulting in a higher necrosis rate after transfection. These results provide a potential method for early diagnosis and treatment of cancer using specific spin trapping probe targeting tumor cells.

Objective To explore the efficacy of blunt separation method in midline catheter intubation in elderly patients with coagulation dysfunction.Methods A total of 80 elderly patients with coagulation dysfunction were selected in the convenience sampling method from October 2022 to April 2023 in our hospital,and they were randomly divided into an experimental(blunt)group and a control(routine)group,with 40 patients in each group.The differences in the degree of bleeding and exudation at the puncture site,the pain score and the incidence of complications(including bleeding and exudation,phlebitis,symptomatic catheter-related thrombus,catheter blockage,catheter pulling-off)were compared between 2 groups.Results In the experimental group,the degree of bleeding and exudation at the puncture point immediately after the operation,degree of bleeding and exudation at the puncture point 24 hours after the operation,pain score 1 day after the catheterization,pain score 3 days after the catheterization,incidence of bleeding and exudation,total incidence of complications and maintenance times were significantly lower than these in the control group(P＜0.05).In terms of the pain score immediately after the operation,pain score 5 days after the operation,incidence of phlebitis,incidence of symptomatic catheter-related thrombosis,incidence of catheter blockage,incidence of catheter pulling-off,incidence of catheter related skin injury,incidence of unplanned extubation,success rate of one-time sheath delivery and the indwelling time,the differences between the experimental group and control group were not significant(P＜0.05).Conclusion The application of blunt separation method in midline catheter indwelling can significantly reduce the incidence and degree of bleeding at the puncture point,decrease the maintenance times and relieve the pain in elderly patients with coagulation dysfunction.

Background: Right upper lobectomy (RUL) for lung cancer with different dissecting orders involves the most vari-able anatomical structures, but no studies have analyzed its effects on postoperative recovery. This study compared the conventional surgical approach, VAB (dissecting pulmonary vessels first, followed by the bronchus), and the alter-native surgical approach, aBVA (dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients. Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into aBVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop-erative outcomes. Results: Three hundred one patients were selected (109 in the aBVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the aBVA cohort than in the VAB cohort (164 vs. 221 min, P < 0.001), and less blood loss occurred in the aBVA cohort (92 vs. 141 mL, P < 0.001). The rate of conversion to thoracotomy was lower in the aBVA cohort than in the VAB cohort (0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the aBVA cohort than in the VAB cohort (3.6 vs. 4.5 days, P = 0.001). The rates of postoperative complica-tions were comparable (P = 0.629). The median overall survival was not arrived in both cohorts (P > 0.05). The median disease-free survival was comparable for all patients in the two cohorts (not arrived vs. 41.97 months) and for patients with disease recurrences (13.25 vs. 9.44 months) (both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences (6.4% vs. 7.8%), distant metastases (10.1% vs. 8.3%), and both (1.8% vs. 1.6%) (all P > 0.05). Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the aBVA approach during RUL would promote surgical feasibility and achieve comparable postoperative recovery for lung cancer patients.

Objective To assess the effectiveness of the Mulliken's method in bilateral complete cleft lip patients with 3dMD system and anthropometric landmarks.Methods Thirty-one infants with bilateral complete cleft lip received treatment in Hospital of Stomatology,Wuhan University between January 2014 and December 2016.Patients underwent primary cheiloplasty and nasoplasty by the same senior surgeon.Periodic review was taken to measure and record the 7 items in the nasolabial area with three-dimensional (3D) images.Results The labial and nasal deformities were restored after primary surgery.The upper lip and nose were corrected and obtained the symmetric shape.The columella was elongated to acquire favorable nasal tip.The arc of nasal fornix was upward.The ridge of the white lipwas continuous and integrated with full vermilion tubercle.Total length of upper lip (Sn-Sto),thickness of the vermilion tubercle (Ls-Sto),protrusion of the nasal tip (Nh) and columellar height (Ch) were markedly improved and there were no significant difference between the observation group and the control group.The significant differences between two groups occurred in values of the nostril width (Nw),which was greater than control group and white lip height (Sn-Ls) and lower than that of control group.Conclusions Mulliken's method during the primary cheiloplasty of the bilateral complete cleft lip shows better results in correction the nasal deformity and the ideal effects are achieved during follow-up.
