Results The volatile oil and constituent content of Pogostemon cablin Benth. reproduced by cuttage was 14.2 mL/kg and 81.31 %,respectively. The volatile oil and constituent content of Pogostemon cablin reproduced by tissue culture was 12.2 mL/kg and 82.98 %,respectively. Conclusion The volatile oil content and constituent content of Pogostemon cablin Benth. reproduced by tissue culture are similar to which reproduced by cuttage.

Objective To compare the effect of ultrafiltration method and activated carbon absorbance method on aconitine-type alkaloid (AA) content in the preparation of Yiqi Huiyang Injection (YHJ) and to evaluate the safety of YHJ by limited detrmination of diester alkaloids (DEA).Methods Acid dye colorimetry was used to detect AA content and reverse phase high performance liquid chromatography (RP-HPLC) was applied to determine the limited content of DEA. Mesaconitine, aconitine, hypaconitine were separated on a Hypersil BDS-C?18?column, with methanol and 0.05% triethylamine (70∶30) as mobile phase, wavelength at 240 nm and external standard for quantitative analysis.Results Compared with activated carbon absorbance method, the loss of AA was reduced, limited content of aconitine was within the pharmacopoeia standard method and the other two kinds of DEA were also low in YHJ prepared by ultrafiltration method.Conclusion Ultrafiltration was superior to activated carbon absorbance in the preparation of YHJ as with AA as the parameter, and the contents of DEA were very low which indicates that the toxicity of YHJ may be also low.

Objective To explore the influence of different injection techniques on the quality of bolus in 99mTc-DTPA renal dynamic imaging.Methods 395 patients accepted 99mTc-DTPA renal dynamic imaging were retrospectively analyzed.All patients were divided into three groups according to injection techniques:direct injection group (187 cases),intravenous route injection group (84 cases)and venous indwelling needle injection group (124 cases).The three groups were injected by each technique.Areas of interest (ROI) were drawn on abdominal aorta by Xeleris workstation in blood flow perfusion imaging.The time-radioactivity curves of ROI were got.The patients whose ROI curve formed a peak was successfully injected,and did not formed was unsuccessfully injected.The number of patients in three groups who were successfully or unsuccessfully injected was respectively calculated.The data of three groups was taken Chisquare test by SPSS17.0 software.Results 174 patients of the direct injection group,46 of the intravenous route injection group and 115 of the venous indwelling needle injection group were injected successfully.The successful rate respectively was 93.0％,54.8％ and 92.7％.The successful rate of the direct injection group and venous indwelling needle injection group were higher than intravenous route injection group.The difference had statistical significance.The successful rate of the direct injection group and venous indwelling needle injection group hadn't statistical significance.Conclusions The successful rates of the direct injection group and venous indwelling needle injection group were similar.The venous indwelling needle injection technique can be chosen.The successful rate of the intravenous route injection group was lower than the other two groups.The intravenous route injection technique should be chosen prudently.

Objective:To observe the pathological changes of levator palpebrae superiors muscle in patients with different severities of simple congenital ptosis (SCP).Methods:Levator palpebrae superiors muscle specimens from 102 eyes of 68 patients with SCP who received levator palpebrae superiors muscle shortening surgery at Wuhan Aier Hankou Eye Hospital from August 2018 to October 2019 were collected as the observation group.According to the severity of ptosis, the specimens were divided into three groups, coverage ≤4 mm group (n=35), coverage >4 mm to ≤6 mm group (n=30), and coverage >6 mm group (n=37). Fresh levator palpebrae superiors muscle tissues from 8 normal donors in Aier Eye Bank of Wuhan Red Cross were selected as the control group.All specimens were performed with Masson trichrome staining and immunohistochemical staining for α-smooth muscle actin (α-SMA), and ImageJ software was used to measure the collagen fiber area ratio, skeletal muscle fiber area ratio and the integrated absorbance (IA) value of α-SMA.Seventeen specimens (2 from the control group, 5 from coverage ≤4 mm group/coverage >4 mm to ≤6 mm group/coverage >6 mm group) were observed with a transmission electron microscope (TEM). This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Wuhan Aier Hankou Eye Hospital (No.HKAIER2018IRB-005-01). All patients and their legal guardians were well informed about the treatment method and the purpose of sampling and voluntarily signed informed consent.Results:Compared with the control group, the skeletal muscle fiber was reduced in number and was in disordered arrangement, and the striation of some muscle fibers disappeared, and hyperplastic fibrous connective tissue was found in intercellular substances in the observation group.The collagen fiber area ratio of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group were significantly higher than that of the control group, and the skeletal muscle fiber area ratio of the three groups was significantly lower than that of the control group (all at P<0.008 3). There were more smooth muscle fibers and positive expression of α-SMA found in the specimens of the observation group.The IA value of α-SMA of the coverage ≤4 mm group, coverage >4 mm to ≤6 mm group, coverage >6 mm group was 7 195.28(5 935.69, 14 058.29), 55 584.18(33 861.88, 80 419.32), 166 507.76(119 121.95, 187 890.86), respectively, which were all higher than 5 543.03(4 867.67, 8 312.02) of the control group, among which, there were statistically significant differences between the control group and the coverage >4 mm to ≤6 mm group, coverage >6 mm group (both at P<0.008 3). Abundant organelles and some damaged mitochondria were found in smooth muscle cytoplasm in the observation group with a TEM.But no characteristic structure of smooth muscle cells such as dense patch and dense body was detected.Conclusions:There are abnormal smooth muscle cells in the levator palpebrae superiors muscle of SCP patients, and the dysgenesis of the levator palpebrae superiors muscle may be related to this abnormal muscle cell.

Objective To investigate the causes, diagnosis, treatment and prognosis of misdiagnosing metastatic liver cancer as liver abscess. Methods Clinical data of 4 patients with metastatic liver cancer misdiagnosed as liver abscess in Department of General Surgery, the Third Hospital of Shenzhen from April 2012 to April 2013 were retrospectively analyzed. The informed consents of all patients were obtained and the ethics committee approval was received. There were 1 male and 3 females with age ranging from 44 to 67 years old and a median age of 54 years old. All the patients received tests such as blood routine, liver function, alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9) and so on, and examinations of hepatobiliary ultrasonography, computed tomography (CT) scan of the upper abdomen, gastroscope and colonoscope after admission to hospital. Results The mean temperature of patients was (37.8±0.8)℃when admitted in hospital. Two cases got fever and shivering, and 4 cases suffered upper abdominal pain or discomfort. There were 2 cases with increasing white blood cell (WBC) and increasing alkaline phosphatase (ALP), 3 cases with increasing CA19-9, 2 cases with increasing CEA and 1 case with increasing AFP. By ultrasound examination and CT , multiple lesions were observed in 3 cases and single lesion in 1 case, including 2 cases of cystic lesions. Obvious edge enhancement was found in 3 cases by CT scan, heterogeneous internal enhancement in 2 cases, no internal enhancement in 2 cases, and 3 cases were found with lymphadenectasis in the porta hepatis or retroperitoneum. By pathological examination, 2 cases were diagnosed with liver metastasis of colon cancer, 1 case with liver metastasis of gastric cancer. And 1 case was clinically diagnosed with liver metastasis of gastrointestinal tract or extrahepatic bile duct cancer. Two cases received anti-infection treatment after admission to hospital. One case received liver tumor biopsy+catheter drainage of liqueifed necrotic tissues, and 1 case received colon cancer resection for intestinal obstruction. All the 4 patients received chemotherapy. One case died of multiple organ failure 3 months after being diagnosed and 1 case who had undergone colon cancer resection still received chemotherapy and lived well till the date of paper submission. The other 2 cases were in poor condition. Conclusions Some patients with metastatic liver cancer are usually misdiagnosed as liver abscess because of the untypical clinical features. The tumor marker detection is helpful for the differential diagnosis. Comprehensive treatments with the main of surgical resection should be employed in the patients but the prognosis is poor.

Objective:To explore the effect of sliding tarso-conjunctival flap combined with allogeneic scleral transplantation for one-stage reconstructing posterior eyelid defect.Methods:The clinical data of eyelid tumor patients who admitted to Hankou Aier Eye Hospital from January 2015 to March 2019 were collected. The lesions crossed the gray line and the tarsal plates were involved. The benign tumor was removed from the margin by 1-2 mm and the pathological examination was performed. Mohs method (intraoperative delivery of frozen sections to control the cut edge) resection was performed for malignant tumor. The residual tarsal plate in the vertical direction after tumor was removed (upper eyelid≥3 mm, lower eyelid ≥2 mm). The posterior defect reconstruction was performed by sliding the residual tarsal conjunctival flap to the eyelid margin, and the posterior tarsal defect was repaired with allogeneic sclera. The anterior defect was reconstructed with sliding flaps, rotating flaps and free skin grafts. The postoperative follow-up was performed to observe the morphology of the eyelid margin, the repair of the eyelid defect area, the degree of movement of the eyelid and the function of opening and closing, and lifting.Results:A total of 8 cases were included, 3 males and 5 females, aged 31-76 years, with an average of 42 years old. 2 cases of eyelid intradermal nevi, 1 case of eyelid basal cell carcinoma, 4 cases of eyelid adenocarcinoma, and 1 case of eyelid squamous cell carcinoma. All patients were followed up for 6 to 24 months. All of the 8 patients had no tumor recurrence. Aside from the absence of eyelashes in the reconstructed area, the eyelids were in good shape. The movement of eyelid was good, the functions of opening and closing and lifting were normal. Patients did not complain about foreign body sensation. No allogeneic sclera dissolution or rejection.Conclusions:For the residual tarsal plate in the vertical direction after tumor resection (upper eyelid≥3 mm, lower eyelid≥2 mm). The use of the sliding tarso-conjunctival flap combined with allogeneic scleral transplantation to reconstruct the posterior layer of the eyelid defect can achieve satisfactory result in both appearance and function.

Objective? To evaluate the effects of the intelligent nursing and transfusion system on transfusion management in patients with growth hormone adenoma complicated with cardiomyopathy. Methods? The patients with growth hormone adenoma complicated with cardiomyopathy treated in the Department of Neurosurgery in a ClassⅢ Grade A hospital from January 2018 to May 2019 were selected. Totally 78 patients receiving conventional transfusion management from January to October 2018 were included into the control group, while 70 patients admitted from November 2018 to May 2019 after the intelligent nursing and transfusion system was applied were included into the experimental group. The incidence rate of adverse effects in transfusion, correct rate of transfusion speed, incidence rate of arrhythmia and patients' compliant rate in terms of transfusion were evaluated between the two groups. Results? The incidence rate of adverse effects in transfusion in the experimental group was 5.7%, lower than 16.7% in the control group. The correct rate of transfusion speed was 97.0% in the experimental group, higher than 89.3% in the control group, and there was statistically significant difference between the two groups (P＜0.05). The incidence rates of arrhythmia in the experimental and control groups were 3.6% and 6.7%, respectively, and there was no statistically significant difference between the two groups (P＞0.05). The compliant rate about transfusion was 5.7% in the experimental group, lower than 16.7% in the control group, and there was statistically significant difference between the two groups (P＜ 0.05). Conclusions? The intelligent nursing and transfusion system can improve transfusion management in clinical practice, which not only reduce the incidence rate of adverse effects in transfusion and improve the transfusion safety in patients with growth hormone adenoma complicated with cardiomyopathy, and also reduce the compliant rate about transfusion and improve patients' satisfaction.
