To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To investigate the efficacy and safety of laparoscopic repair in children with congenital esophageal hiatal hernia. Methods From September 2001 to December 2008,seven children with congenital esophageal hiatal hernia,including 4 boys and 3 girls,were treated by laparoscopic repair and Nissen's fundoplication in our hospital. One of them received laparoscopic pyloroplasty in the meanwhile because of delayed gastric emptying (confirmed by preoperative gastrointestinal angiography); one child underwent laparoscopic high ligation due to right oblique inguinal hernia; spleneolus was found in one patient,no further treatment was carried out. Results The procedures were completed in all of the patients without conversion to open surgery. The mean operation time was 94.2 min (75-150 min) in this series,and the average blood loss was 5 ml (2-10 ml). No patient received blood transfusion after the surgery. The children began to intake milk or regular diet in 24-48 hours after the operation. They were discharged from hospital in a mean of 4.5 days (ranged from 3 to 7 days). Then,the children were followed up for 6 to 20 months (mean,12.6 months). One of the patients suffered from vomiting on the 10th day after the operation,1 patient showed recurrence in 1 year postoperation and then was cured by a second operation. The other five patients were healthy during the follow-up. Conclusions Laparoscopic repair of congenital esophageal hiatal hernia is a safe,effective,and minimally invasive procedure. It is feasible for patients complicated with other diseases. The indications for the surgery must be strictly selected.

Objective To explore the value of laparoscopic partial nephrectomy for children with duplex kidney.Methods Between June 2006 and February 2009,we performed laparoscopic partial nephrectomy on totally 21 children with duplex kidney.Three or four trocars were used for the operation.Through transabdominal approach the peri-renal tissues were freed and the vessels supplying the duplicated kidney were ligated.Afterwards,we resected the duplicated kidney,as well as the ureter,and a subperitoneal drainage tube was indwelt.Results The operation was completed in all of the 21 cases without conversion to open surgery.The mean operation time for laparoscopy was 190 min(range,130 to 210 min).The intraoperative blood loss ranged from 5 to 10 ml.No patient received blood transfusion.Liquid diet was given in 8 to 10 hours after the operation.In this series,the postoperative hospital stay ranged from 5 to 7 days with a mean of 6.2 days.Follow-up was available for 3 to 28 months in the cases(mean,20.2 months).During the period,the clinical symptoms disappeared and B ultrasonography showed no abnormalities.Conclusions Providing larger operation space and better exposed surgical field,laparoscopic partial nephrectomy for children with duplex kidney is feasible and safe with quicker recovery.

Objective To investigate the effect of integrated traditional Chinese and western medicine in the treatment of postoperative pain in patients with anorectal diseases. Methods From November 2015 to October 2017, 70 patients with anorectal diseases underwent surgical treatment in the First People 's Hospital of Yongkang were selected. The simple western medicine treatment was performed in 35 patients with anorectal diseases in the control group,and 35 patients in the observation group were given combined Chinese and western medicine. The total effective rate of the two groups was observed and calculated. The pain score at 2 h,6 h,12 h and 24 h after operation,the incidence rate of postoperative complications were observed. Results The total effective rate of the control group (80. 00％ ) was lower than that of the observation group (97. 14％ ),the difference was statistically significant(χ2 =5. 080,P < 0. 05). The pain scores at postoperative 2h,6h,12h,24h in the control group were (2. 0 ± 0. 5) points, (3. 6 ± 1. 0)points,(4. 5 ± 1. 0)points,(5. 0 ± 1. 2)points,respectively,which in the observation group were (1. 4 ± 0. 2)points,(2. 0 ± 0. 6)points,(2. 4 ± 0. 5)points,(2. 3 ± 0. 4)points,respectively,the differences were statistically significant(t = 6. 591,8. 116,11. 112,8. 116,all P < 0. 05). The incidence rate of postoperative complications in the control group (17. 14％ ) was higher than that in the observation group (2. 86％ ),the difference was statistically significant(χ2 = 3. 968,P < 0. 05). The total satisfaction rate of the control group (74. 29％ ) was lower than that of the observation group (94. 29％ ),the difference was statistically significant(χ2 = 5. 285,P < 0. 05). Conclusion The combination of traditional Chinese and western medicine is effective in the treatment of postoperative pain in patients with anorectal diseases,which can increase the effective rate and improve the quality of life of the patients, and it is worthy of clinical application.

Objective To investigate the value of high-frequency ultrasound in diagnosis of thyroid carcinoma by comparative analysis of high-frequency ultrasound and spiral CT imaging results. Methods The imaging results of patients with thyroid carcinoma proved by postoperative pathology or biopsy results were reviewed.High-frequency ultrasound and spiral CT were used to examine the 35 patients in The Tumor Hospital of Harbin Medical University between 2007 and 2009. Results Diagnosis of thyroid carcinoma by application of Highfrequency ultrasound were 27 cases, diagnosis rate was 77.1%(27/35);by spiral CT were 25 cases, diagnosis rate was 71.4% (25/35);comparison of the two methods showed no significant difference (x2= 0.3, P ＞ 0.05). Combined application of high-frequency ultrasound and spiral CT diagnosed 33 patients with thyroid carcinoma, diagnosis rate was 94.3%(33/35), which was significantly higher than that of high-frequency ultrasound alone or that of spiral CT alone(compared with high-frequency ultrasound, x2 = 4.2, P ＜ 0.05;and spiral CT, x2 = 6.4, P ＜ 0.05). Conclusion Combined application of high-frequency ultrasound and spiral CT can improve the diagnosis rate of thyroid carcinoma.

Background Tight junctions are thought to play a significant role in the maintenance of the corneal epithelial defense for the eye,and the restoration of the tight junctions is critical during epithelial wound healing after refractive surgery.However,there are few reports about this study. Objective The aim of this study was to investigate and compare the expression of occludin in corneal epithelium following flap-free epipolis laser insitu keratomileusis (Epi-LASIK) and laser-assisted subepithelial keratectomy ( LASEK ). Methods Forty-eight clean New Zealand white rabbits were randomized into 2 groups,and 24 rabbits for each group.Flap-free Epi-LASIK and LASEK were performed in the right eyes of the rabbits in two groups,and other 2 age matched normal rabbits were as normal controls.The animals were sacrificed and the corneal samples were obtained at 1,2,3,5 days after surgery.Immunofluorescence staining was used to detect the expression of occludin in the corneal epithelium,and RT-PCR was used to identify the level of occludin mRNA in the central cornea. Results Occludin protein was expressed innormal corneal epithelium and showed the green fluorescence with the regular arrangement.The fluorescence intensity was lower in 1 -2 days in LASEK group with the irregular arrangement;while the fluorescence signal in corneal epithelium was stronger in flap-free Epi-LASIK group.3-5 days after surgery,the fluorescence intensities were bothenhanced in two groups.RT-PCR showed that the relative expression of occludin mRNA in corneal epithelium was 0.11 ±0.02,0.25 ± 0.03,0.43 ± 0.04 in LASEK group 1,2,3 days after surgery,respectively,and was lower than those of flap-free Epi-LASIK group ( 0.20± 0.04,0.44 ± 0.04,0.76 ± 0.04 ),showing significant differences between these two groups ( t =6.476,12.898,17.315,P＜ 0.05 ).No significant difference was seen in the expression of occludin mRNA in 5 days after surgery between two groups( t=-0.733,P＞0.05).The relative values of occludin mRNA expression in corneal epithelium were gradually increased with time prolongation,presenting a significant difference among various time points ( Ftime =768.903,P =0.000). Conclusions The reformation of occludin in flap-free Epi-LASIK group is faster than that in LASEK group.Therefore,flap-free Epi-LASIK is prominant in reducing the stimulated symptoms and complication after the surgery.

To ascertain the optimal harvest period of Lonicera Flos (Lonicera macranthoides) the configuration yield and quality of L. macranthiodes bloom verity and bud verity flower at different develop periods were Observed. The quality of L. macranthiodes which harvested at different times of the day was Compared. The configuration was significant difference between different develop period of L. macranthiodes flower. As bud growth, yield increased. Bloom verity of L. macranthoides chlorogenic acid content was significantly lower after opening (silver flower stage, golden flower stage), before opening (young bud stage, green-white stage) have no significant difference of the quality. Bud verity of L. macranthoides macranthoidin B is significant lower at yellow-white stage, young bud stage and green-white stage have no significant difference of the quality. The chlorogenic acid and isochlorogenic acid A content is significant difference between L. macranthoides harvested at different time of the day. The optimal harvest period of bloom verity is the white stage, picking time for 10:00 before and after 18:00. The optimal harvest period is the green-white stage, picking time is 8:00 before and after 18:00.
