Objective　To study the role of α1-antichymotrypsin(α1-ACT)in the pathogenesis of childhood asthma for providing a theoretical base for prevention and treatment of childhood asthma. Methods　Levels of plasma α1-ACT in 30 asthmatic children and 30 healthy children were determined by rocket immunoelectrophoresis. Results　Plasma α1-ACT levels were higher in acute phase than in paroxysmal phase ［（0.4178±0.0815）vs(0.2865±0.0799), t=6.301,P<0.001］ and also higher in asthma group than in control group ［（0.4178±0.0815）vs(0.2876±0.0496),t=7.474,P<0.001］. The plasma α1-ACT levels in asthma group and control of paroxysmal phase were similor ［(0.2865±0.0799) vs (0.2876±0.0496),t=0.064, P>0.05］. The levels of plasma α1-ACT were higher in moderate and heavily attacked patients than that in mild attacked patients ［(0.4553±0.0758) vs (0.3249±0.0926),t=4.187,P<0.001］ and those in control group ［(0.4553±0.0758) vs (0.2865±0.0799),t=9.38,P<0.001］. Conclusion　α1-ACT is involved in pathophysiological course of childhood asthma. Measurement of plasma α1-ACT levels may be helpful in determining the state of the illness and to evaluate the severity and treatment of childhood asthma.

ObjectiveTo investigate long-term effect on radiofrequency heat-coagulation (RF)endometrial ablation in treatment of anovulatory dysfunctional uterine bleeding (DUB). MethodsFrom Jul.2001 to Nov. 2009, 1 196 patients with DUB who were failed by medical treatment( including 127 patients with dysmenorrheal) were enrolled into this study in Jinan Millitary General HospitaL Those patients were divided into two groups according to age:427 patients at age of or more than 45 years (average age 48 years) in Group A who were treated by RF procedure for amenorrhea;769 patients at age of less than 45 years old (average 37 years) in group B were treated by RF for controlling excessive menstrual bleeding. All the patients had the results of menstrual score (pictorial blood loss assessment chart, PBAC), hemoglobin (Hb) ,endometrial curettage pathology and hysteroscopy examination immediately after RF procedure; Some patients still had another endometrial curettage pathology and clinical results in 6 months after RF. The mean follow-up time was 72 months ( range:6 to 100 months). The evaluation criterion for RF treatment was to use optimal and significant effect measurements. For group A, the optimal treatment effect (cure) was defined as bleeding cessation and achieving amenorrhea that continued for more than 12 months after treatment. For group B, the optimal treatment effect (cure) was also defined as bleeding cessation and resuming normal menstruation which continued for more than 12 months after treatment. Significant treatment effect was defined as irregular, minor bleeding, but PBAC score less than 100 within 12 months. If patient symptoms and PBAC scores did not change compared with those before treatment, the treatment was defined as failure. For dysmenorrhea, the optimal treatment effect was disappearance for more than 12 months, the significant treatment effect was remission, and treatment failure was not changed from the pre-treatment baseline. The effective rate was the sum of that of the optimal and significant effect. One hundred and twentyfive patients with DUB treated by agents at the same time were chosen as control group. Results( 1 ) The recent and long-term effective rates for bleeding cessation by RF: the total recent effective rates within 1 months were 94. 82％ ( 1134/1196), including 96. 5％ (412/427) in group A and 93.9％ (722/769) in group B. The total curative rates for dysmenorrheal were 82. 7％ ( 105/127 ), including 86. 4％ ( 38/44 ) in group A and 80. 7％ ( 67/83 ) in group B. Pathology examination after hysteroscopy immediately after RF showed a completely and whole destroyed endometrium in group A, and a little rested endometrium in group B. The long-term effect rates for bleeding cessation by RF after 12, 24 and 36 months were 92. 55％ (969/1047), 93.9％ (866/922) and 93.7％ (609/650), respectively. PBAC and Hb in group A and group B within 12, 24, 36 and more than 36 months were improved significantly ( P ＜ 0. 05 ). (2) Complications : the major complication was irregular minor bleeding in 1 to 2 months after treatment, the rate was 8.03％ (96/ 1196). The second one was menorrhea in 3 months after RF, the rate was 5. 18％ (62/1 196 ). This condition was corrected by the second RF. No hysterectomy was performed on those patients. Conclusion RF is the safe, efficient and minimal invasive procedure in treatment for DUB. The mechanism of keeping longterm curative effect and preventing recurrence is due to endonetrium inactivation and fibrosis by thermocoagulation.

OBJECTIVETo observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2.

METHODSTotally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1β and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week.

RESULTSCompared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1β and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1β and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01). Compared with the control group at the same time point,HAMD scores decreased in the treatment group at weekends of the 1st, 2nd,3rd,and 4th week after treatment (P < 0.01),serum levels of 5-HT, IL-4, and IL-10 increased (P < 0.05, P < 0.01), serum levels of IL-6 decreased (P < 0. 01).

CONCLUSIONAcupuncture could accelerate early onset of SSRIs in treating acute phase depressive disorder, and effectively regulate serum 5-HT levels and inflammatory cytokines secreted by TH1/TH2.

OBJECTIVES: Some changes are found in the labyrinth anatomy during postnatal development. Although the spatial orientation of semicircular canals was thought to be stable after birth, we investigated the age-related orientational changes of human semicircular canals during development. METHODS: We retrospectively studied the computed tomography (CT) images of both ears of 76 subjects ranged from 1 to 70 years old. They were divided into 4 groups: group A (1-6 years), group B (7-12 years), group C (13-18 years), and group D (>18 years). The anatomical landmarks of the inner ear structures were determined from CT images. Their coordinates were imported into MATLAB software for calculating the semicircular canals orientation, angles between semicircular canal planes and the jugular bulb (JB) position. Differences between age groups were analyzed using multivariate statistics. Relationships between variables were analyzed using Pearson analysis. RESULTS: The angle between the anterior semicircular canal plane and the coronal plane, and the angle between the horizontal semicircular canal plane and the coronal plane were smaller in group D than those in group A (P<0.05). The JB position, especially the anteroposterior position of right JB, correlated to the semicircular canals orientation (P<0.05). However, no statistically significant differences in the angles between ipsilateral canal planes among different age groups were found. CONCLUSION: The semicircular canals had tendencies to tilt anteriorly simultaneously as a whole with age. The JB position correlated to the spatial arrangement of semicircular canals, especially the right JB. Our calculation method helps detect developmental and pathological changes in vestibular anatomy.

Background Macular hole retinal detachment(MHRD) causes severe decrease of vision.Pars plana vitrectomy has been applied for MHRD.Silicone oil and C3F8 have been used as intraocular tamponade materials,while there are still controversity on their efficacy.Objective This trial was to evaluate the efficacy of vitreous surgery combined with silicone oil or C3F8 tamponade for patients with MHRD in highly myopic eyes.Methods A retrospective case-controlled study was designed.Fifty-one patients who underwent vitrectomy with intraocular tamponade were retrospectively analyzed.The best corrected visual acuity(BCVA) before and after surgery were examined and campared between two groups.The rate of recurrent RD and macular hole closed were analyzed.Results There was no significant difference in BCVA between silicone oil group and C3F8 tamponade group before and after surgery(U=266.000,P =0.286 ; U =205.000,P =0.029).The BCVA after surgery was elevated in both groups (Z=-2.729,P =0.006 ; Z =-3.273,P =0.001).The rates of recurrent RD and macular hole closed were no difference between two groups(P=0.894,1.000).There were no other complications but cataract.Conclusions C3F8 tamponade of MHRD in high myopic eyes show the same efficacy as silicone oil tamponade.

To observe the expression of drebrin in the distal cerebrospinal fluid contacting neurons (dCSF-CNs) of rats with chronic constriction injury (CCI) of sciatic nerve by immunofluorescence technique, male Sprague-Dawley rats were randomly divided into three groups: control group, sham surgery group and CCI group. The behavior of rats was scored. After choleratoxin subunit B-conjugated horseradish peroxidase (CB-HRP, 3 muL) was injected into the lateral cerebroventricle to trace dCSF-CNs, the expression of drebrin was observed in the dCSF-CNs through immunofluorescence double staining and laser scanning confocal microscopy technique. The results showed that only the pain threshold of CCI group was decreased. The dCSF-CNs were clearly displayed in three groups. No drebrin expression was observed in the control and sham groups. In CCI group, drebrin was markedly expressed in intracytoplasm. It is suggested that the technique displaying dCSF-CNs with immunofluorescence is successful and the dCSF-CNs are possibly involved in the transmission of nociceptive information under the neuropathic pain state.
