The prevalence rate of eye symptoms(51.98%), nasal symptoms(58.91%), throat symptoms(48.02%), nausea and vomiting, psychiatric symptoms(68.32%) and cold liability (60.89%) in the exposed group was higher than those in the control group(P

Objective To observe the efficacy of melbine combined with clomifene citrate in treatment of patients with polycystic ovarian syndrome ( PCOS) .Methods 60 patients aged 20 to 39 with PCOS were randomly divided into observation group and control group, 30 patients in each group.In the menstrual cycle of 3~7 d, the control group received clomifene citrate orally (50 mg per time, qd), and the observation group received melbine (2.5 mg per time, qd)combined with clomifene citrate (50 mg per time, qd), with a course of 5 days.Results The number of mature follicles and score of cervical mucus in obsercation group was significant higher than that in control group, respectively(P<0.05).The rate of follicular development and ovulation rate of single follicle in obsercation group was significant higher than that in control group, respectively(P<0.05), but there were no significant differences of pregnancy rate, first trimester abortion rate and periodic ovulation rate between two groups.The rate of endometrial thickness<7 mm patients in observation group was significantly lower and positive rate of three line was higher than that in control group, respectively ( P<0.05).The follicle stimulating hormone level in observation group was significantly lower than that in control group(P<0.05), but there was no significant difference of luteinizing hormone between two groups.Conclusion Melbine combined with clomifene citrate has a good effect on mature follicles number and endometrial thickness in anovulatory infertility women caused by polycystic ovary syndrome.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ￥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.

Objective:To propose a method to evaluate the total body water (TBW) of patients on hemodialysis with urea kinetic model (UKM), and compare it with body surface bio-impedance spectrum (BIS) analysis. Methods:We enrolled 24 adult patients with end stage renal disease (ESRD) without hyper-catabolism in our dialysis center. All of them had been on hemodialysis for more than 3 months. TBW was measured with BIS analysis immediately before and after dialysis session, and one hour after hemodialysis session. Spent dialysate was collected; blood samples were taken before and one hour after hemodialysis session, TBW before hemodialysis session were calculated by UKM. Results:Patients were 6 men and 18 women, the average age was (51.2?13.5) years and the average time on dialysis was (33.2?36.7) months. Causes of ESRD included chronic glomerulonephritis (8 patients), diabetic nephropathy (1 patients), hypertensive renal damage (1 patients), interstitial nephritis(two patients), chronic pyelonephritis (two patients). The average ultrafiltration volume was (2.7?1.0) L (0.5-4.4 L) . Plasma urea concentrations were (23.06?5.76) mmol/L and (8.15?2.06) mmol/L before and one hour after hemodialysis session, respectively. There was no significant difference between TBW measured immediately after and one hour after hemodialysis session with BIS analysis [(29.9?8.8) L and (29.8?8.6) L, respectively; average difference was (0.1?0.9)L, P=0.70]. These two measurements correlated very well (Pearson r=0.99, P

Objective To investigate the expression of integrin β1 and VEGF in gastric carcinoma and evaluate its correlation with invasion and metastasis.Methods Immunohistochemistry techniques were used to study the expression of integrin β1 and VEGF in 63 gastric carcinoma specimens.We analyzed the variance with histological grade and stage and classification of clinical date.Results No significant relationship was observed among age,sex and histological classification of the expression of integrin β1 in the gastric cancer group (P>0.05).With the depth of invasion and lymphatic metastasis increasing,integrin β1 expression improved.The positive rate of integrin β1 among tubular adenocarcinoma,papillary carcinoma,mucinous carcinoma and undifferentiated carcinoma was 70.00 %,55.56 %,57.14 % and 64.86 %.No significant relationship was observed in it.Integrin β1 in cases with lymphnode metastasis was significantly higher than those without lymph node metastasis (P<0.05).No significant relationship was observed among VEGF expression and age,sex,histological classification and depth of invasion (P>0.05).Significant relationship was observed among VEGF expression and lymphatic metastasis.VECF in cases with lymph node metastasis was significantly higher than those without lymph node metastasis (P<0.05).Conclusion Immunohistochemistry techniques indicated that integrin β1 participated in the procession of invasion and metastasis.The expression of integrin β1 and VEGF are important factor,forecasting the invasion and metastasis.VEGF is an important factor for lymphnade metastasis of gastric carcinoma.VEGF in cases with lymphnode metastasis was significantly higher than those without lymphnode metastasis(P<0.05).The usage of integrin β1 and VEGF will improve the rightness in forecasting the invasion and lymph node metastasis of gastric carcinoma.

Objective This study intends to explore the impacts of the establishment of chest pain center(CPC) on the door-to-balloon(D-to-B) time in patients with ST-elevation myocardial infarction (STEMI) by different transfer ways to hospital. Methods A regular CPC and a regional cooperative network were established based on the pre-hospital transmitted real-time 12-lead electrocardiogram system. The STEMI patients were divided into the following three groups by the different transfer ways to hospital before and after the establishment of chest pain center:self-referral groups (group A1, n=52, and group A2, n=65), EMS (emergency medical service ) groups (group B1, n=31, and group B2, n=92) and transfer PCI groups (group C1, n=23, and group C2, n=552). The mean D-to-B time and the rate of D-to-B below 90 minutes were compared between before and after the establishment of CPC and the reasons of reperfusion delay were analyzed. Results There were no statistical differences of the average D-to-B time [(123±78) min vs.(140±123)min, P > 0.05] and the rate of D-to-B time below 90 min (44.2%vs. 46.2%) between group A1 and group A2. The average D-to-B time was significantly shortened in group B2 [(89±66)min] while compared with that in group B1 [(155±115)min, P<0.05] and the rate of D-to-B time below 90 min was remarkably elevated in group B2 compared with that of group B1 (69.6%vs. 32.3%, P<0.05). The average D-to-B time was significant shorter in group C2 than in group C1 [(77±43)min vs. (337±662)min, P<0.05] and the rate of D-to-B time below 90 min was remarkable higher in group C2 than in group C1 (75.7%vs. 21.7%, P<0.05). The longer D-to-B time in self-referral groups was mainly due to the delay of getting informed consent before PCI when occupied catheterization laboratory was the major cause of reperfusion delay in EMS groups and transfer PCI groups. Conclusions The establishment of CPC may significantly shorten the D-to-B time and increase the rate of D-to-B time below 90 min for these patients admitted by EMS and transferred from non-PCI hospitals. However, the pathway for the self-referral patients should be further modified.

Objective To evaluate the pre-hospital diagnostic reliability of real-time tele-transmission of 12-lead electrocardiogram of patients with ST-segment elevated acute myocardial infarction (STEMI).Methods The 12-lead electrocardiogram was simultaneously recorded with real-time tele-transmission system and a conventional electrocardiograph in 40 STEMI cases.The width and amplitude of each wave,the deviated amplitude of ST-segment in the same leads were compared by t-test and rank-sum test.Results There were no statistical differences in the width and amplitude of P wave,QRS wave and t wave as well as the deviated altitude of ST-segment between the two separate electrocardiographs (P ＞0.05).There was a significant positive correlation between the two ECG devices in respect of ST-segment elevated altitude (r =0.912,P =0.000).The differential ability of ST-segment elevation between two separate ECG devices kept highly consistent (Kappa value:0.976).Conclusions Real-time tele-transmission of 12-lead electrocardiogram is reliable for the pre-hospital diagnosis of STEMI.

Objective: To observe and compare the clinical effects of different electroacupuncture waveforms on primary dysmenorrhea. Methods: This was a prospective, randomized, three-group, parallel-controlled trial. Participants with primary dysmenorrhea were randomly divided into dense-sparse wave, continuous wave, and discontinuous wave groups in a 1:1:1 ratio. Two lateral Ciliao (BL 32) points were used. All three groups started treatment 3–5 days before menstruation, once a day for six sessions per course of treatment, one course of treatment per menstrual cycle, and three menstrual cycles. The primary outcome measure was the proportion with an average visual analog scale (VAS) score reduction of ≥50% from baseline for dysmenorrhea in the third menstrual cycle during treatment. The secondary outcome measures included changes in dysmenorrhea VAS scores, Cox Menstrual Symptom Scale scores and the proportion of patients taking analgesic drugs. Results: The proportion of cases where the average VAS score for dysmenorrhea decreased by ≥50% from baseline in the third menstrual cycle was not statistically significant (P > .05). Precisely 30 min after acupuncture and regarding immediate analgesia on the most severe day of dysmenorrhea, there was a statistically significant difference in the dense-sparse wave group compared with the other two groups during the third menstrual cycle (P < .05). Additionally, there was a statistically significant difference between the dense-sparse wave and discontinuous wave groups 24 h after acupuncture (P < .05). Conclusions Waveform electroacupuncture can alleviate primary dysmenorrhea and its related symptoms in patients. The three groups showed similar results in terms of short- and long-term analgesic efficacy and a reduction in the number of patients taking analgesic drugs. Regarding achieving immediate analgesia, the dense-sparse wave group was slightly better than the other two groups.

Objective To explore the effects of target value management for quality control indexes in chest pain center on the efficiency and effectiveness of in-hospital treatment for STEMI patients.Methods The database of Chest Pain Center in General Hospital of Guangzhou Military Command was retrospectively analyzed.STEMI patients who visited our hospital from March 2011 to March 2018 were selected as the research subjects.During the review period,the target values of quality control indexes were adjusted 4 times.Before and after the 4 adjustment,the efficiency indexes of in-hospital treatment STEMI patients were compared,including the first medical contact to the first electrocardiogram (FMC2ECG) time,catheter lab activation time and Door-to-Balloon (D2B) time.Length of hospital stay,in-hospital mortality and hospitalization cost were compared as well.Results A total of 332 STEMI patients were included in the study.As the quality control target values became stricter,the median and the average value of FMC2ECG time,catheter lab activation time and D2B time showed a downward trend.Among these data,the D2B time decreased from 95 (74,134.5) min to 50 (44.5,71) min,and its differences were of the most significance.However,there is no significant difference in the hospitalization cost,length of hospital stay and in-hospital mortality of STEMI patients.Conclusions The target value management of quality control indexes can improve the in-hospital treatment efficiency for STEMI patients,but the improvements of treatment efficiency and effectiveness cannot be immediately revealed.It takes a certain amount of time and needs enough cases to reach a significant difference.
