Objective: To seek the optimal acupuncture time for primary dysmenorrhea and provide clinical basis for optimal acupuncture treatment protocol. Methods:A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan (CV 4), bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for patients in all three groups, with a different treatment duration: 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results:As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups (allP<0.05); coupled with statistically significant inter-group differences between group B and the other two groups (bothP<0.05). As for clinical efficacy, there were statistical differences between group B and the other two groups (bothP<0.05), indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion:With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.

Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.

Objective To establish a uremic apoE-/- mouse model to observe serum biochemical parameters and features of aortic root atherosclerosis (AS) in the model. Methods A uremic model was induced surgically in apoE-/- mice: electrocautery of the right kidney at 8 weeks of age and nephrectomy (NX) of the left one 2 weeks later. Control mice were sham-operated. Two weeks after NX, renal functions were detected in the uremic and control mice to evaluate the efficiency of the model. After 10 weeks of NX, blood samples were taken to determine serum biochemical parameters, and aortic root was collected for frozen sections to investigate the lesion features of AS. Results Two weeks after NX, renal functions declined significantly in the uremic mice compared with the control ones, and remained stable 8 weeks later either in males or in females. Ten weeks after NX, serum levels of TCH, TG and LDL-C were dramatically higher in the uremic mice than in the controls, whereas no differences in serum HDL-C or glucose concentration were found between the two groups. Aortic root plaque relative area increased significantly in the uremic mice compared with the controls either in males or in females; more-over, the lesion area was larger in female mice than in male ones. Conclusion We established a uremic apoE-/- mouse model successfully, and this model is characterized by accelerated atherogenesis which is associated with an increase in serum lipid profile. This experimental model can be a useful tool to study the pathogenesis and therapeutic strategies of uremic AS.

AIM: To evaluate the efficiency and complications of single lacrimal duct intubation versus annular lacrimal duct intubation with 5-fluorouracil and tobramycin/dexamethasone eye ointment injection in lacrimal duct obstruction treatment.METHODS:A total of 74 patients (92 eyes) with lacrimal duct obstruction who received surgical treatment by Department of Ophthalmology in Qinhuangdao Haigang Hospital were consecutively recruited between August 2015 and September 2016.They were randomly allocated to Group A or Group B.After probing of lacrimal passage, Group A (46 eyes) were treated by using single lacrimal duct intubation.Group B (46 eyes) were treated by using annular lacrimal duct intubation combined with 5-fluorouracil and tobramycin/dexamethasone eye ointment injection.Between the two groups, Mann-Whitney Rank sum test was used to comparing the operative effect, and Chi-square test was used to comparing the occurrence of complications.RESULTS:The cure rate was 61% in Group A and 89% in Group B;the improvement rate was 22% in Group A and 4% in Group B.Group B had better effect and less complications (2 cases) than Group A (8 cases),the differences between the two groups were significantly(P<0.05).CONCLUSION: Compared with single lacrimal duct intubation, annular lacrimal duct intubation combined with 5-fluorouracil and tobramycin/dexamethasone eye ointment injection has better operative effect and less complication in lacrimal duct obstruction treatment.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

The clinical analgesic effect of electro-acupuncture (EA) stimulation (EAS) on breakthrough pain induced by remifentanil in patients undergoing radical thoracic esophagectomy, and the mechanisms were assessed. Sixty patients (ASAIII) scheduled for elective radical esophagectomy were randomized into three groups: group A (control) receiving a general anesthesia only; group B (sham) given EA needles at PC4 (Ximen) and PC6 (Neiguan) but no stimulation; and group C (EAS) electrically given EAS of the ipsilateral PC4 and PC6 throughout the surgery. The EAS consisting of a disperse-dense wave with a low frequency of 2 Hz and a high frequency of 20 Hz, was performed 30 min prior to induction of general anesthesia and continued through the surgery. At the emergence, sufentanil infusion was given for postoperative analgesia with loading dose of 7.5 μg, followed by a continuous infusion of 2.25 μg/h. The patient self-administration of sufentanil was 0.75 μg with a lockout of 15 min as needed. Additional breakthrough pain was treated with dezocine (5 mg) intravenously at the patient's request. Blood samples were collected before (T1), 2 h (T2), 24 h (T3), and 48 h (T4) after operation to measure the plasma β-EP, PGE2, and 5-HT. The operative time, the total dose of sufentanil and the dose of self-administration, and the rescue doses of dezocine were recorded. Visual Analogue Scale (VAS) scores at 2, 12, 24 and 48 h postoperatively and the incidence of apnea and severe hypotension were recorded. The results showed that the gender, age, weight, operative time and remifentanil consumption were comparable among 3 groups. Patients in EAS group had the lowest VAS scores postoperatively among the three groups (P<0.05). The total dose of sufentanil was 115±6.0 μg in EAS group, significantly lower than that in control (134.3±5.9 μg) and sham (133.5±7.0 μg) groups. Similarly, the rescue dose of dezocine was the least in EAS group (P<0.05) among the three groups. Plasma β-EP levels in EAS group at T3 (176.90±45.73) and T4 (162.96±35.00 pg/mL) were significantly higher than those in control (132.33±36.75 and 128.79±41.24 pg/mL) and sham (136.56±45.80 and 129.85±36.14 pg/mL) groups, P<0.05 for all. EAS could decrease the release of PGE2. Plasma PGE2 levels in EAS group at T2 and T3 (41±5 and 40±5 pg/mL respectively) were significantly lower than those in control (64±5 and 62±7 pg/mL) and sham (66±6 and 62±6 pg/mL) groups. Plasma 5-HT levels in EAS group at T2 (133.66±40.85) and T3 (154.66±52.49 ng/mL) were significantly lower than those in control (168.33±56.94 and 225.28±82.03) and sham (164.54±47.53 and 217.74±76.45 ng/mL) groups. For intra-group comparison, plasma 5-HT and PGE2 levels in control and sham groups at T2 and T3, and β-EP in EAS group at T3 and T4 were significantly higher than those at T1 (P<0.05); PGE2 and 5-HT levels in EAS group showed no significant difference among the different time points (P>0.05). No apnea or severe hypotension was observed in any group. It was concluded that intraoperative ipsilateral EAS at PC4 and PC6 provides effective postoperative analgesia for patients undergoing radical esophagectomy with remifentanil anesthesia and significantly decrease requirement for parental narcotics. The underlying mechanism may be related to stimulation of the release of endogenous β-EP and inhibition of inflammatory mediators (5-HT and PGE2).

AIM: To evaluate the operative effect and time effectiveness of the conventional surgery versus retrograde gas injection under nasal endoscope combined 5-Fluorouracil for lacrimal canalicular rupture.
●METHODS:A total of 67 patients (67 eyes) with lower lacrimal canalicular rupture who received surgical treatment by Department of Ophthalmology in Qinhuangdao Haigang Hospital were consecutively recruited between Jan. 2009 and Dec. 2015. They were randomly divided into Group A or Group B. Group A (33 patients, 33 eyes) were treated by conventional surgery, and Group B ( 34 patients, 34 eyes ) were treated by retrograde gas injection under nasal endoscope combined 5-Fluorouracil. Time for finding out the cute end of the lower lacrimal canaliculus and postoperative effect were recorded. Comparisons between the two groups were done with lndependent sample t-test and Mann-Whitney Rank sum test.
●RESULTS: Time for finding out the cute end of the lower lacrimal canaliculus of Group A was (44. 42±10. 66) min, and the time of Group B was ( 30. 06 ± 6. 21 ) min. There was significant difference between the two groups (t=6. 72, P<0. 05). Lacrimal ducts flush was done at the 6mo after the survey, Group B had better effect than Group A, the difference between the two groups were significant (Z=2. 47,P<0. 05).
●CONCLUSION: Compared with conventional surgery, retrograde gas injection under nasal endoscope combined 5-Fluorouracil for lacrimal canalicular rupture can make the operation time shorter and has better effect.

The metabolic characteristics of ligustrazin (TMPz) in liver microsomes were investigated in the present study. The reaction phenotyping of TMPz metabolism was also identified by in vitro assessment using recombinant human cytochrome P450 enzymes (CYP) and UDP glucuronosyltransferases (UGT). TMPz was incubated at 37 degrees C with human (HLM) and rat liver microsomes (RLM) in the presence of different co-factors. The metabolic stability and enzyme kinetics of TMPz were studied by determining its remaining concentrations with a LC-MS/MS method. TMPz was only metabolically eliminated in the microsomes with NADPH or NADPH+UDPGA. In the HLM and RLM with NADPH+UDPGA, t1/2, K(m) and V(max) of TMPz were 94.24 +/- 4.53 and 105.07 +/- 9.44 min, 22.74 +/- 1.89 and 33.09 +/- 2.74 micromol x L(-1), 253.50 +/- 10.06 and 190.40 +/- 8.35 nmol x min(-1) x mg(-1) (protein), respectively. TMPz showed a slightly higher metabolic rate in HLM than that in RLM. Its primary oxidative metabolites, 2-hydroxymethyl-3, 5, 6-trimethylpyrazine (HTMP), could undergo glucuronide conjugation. The CYP reaction phenotyping of TMPz metabolism was identified using a panel of recombinant CYP isoforms (rCYP) and specific CYP inhibitors in HLM. CYP1A2, 2C9 and 3A4 were found to be the major CYP isoforms involved in TMPz metabolism. Their individual contributions were assessed b) using the method of the total normalized rate to be 19.32%, 27.79% and 52.90%, respectively. It was observed that these CYP isoforms mediated the formation of HTMP in rCYP incubation. The UGT reaction phenotyping of HTMP glucuronidation was also investigated preliminarily by using a panel of 6 UGT isoforms (rUGT). UGT1A1, 1A4 and 1A6 were the predominant isoforms mediated the HTMP glucuronidation. The results above indicate that the metabolism of TMPz involves multiple enzymes mediated phase I and phase II reactions.
