OBJECTIVE: To evaluate the clinical effectiveness and safety of the Chinese medicine (CM) Qixiong Zhongzi Decoction (, QZD) in the treatment of patients with idiopathic asthenozoospermia. METHODS: A total number of 66 patients with idiopathic asthenozoospermia were included and randomly divided into treatment and control groups by SAS-generated code from January 2015 to August 2016, 33 patients in each group. Patients in the treatment group were administered with 150 mL of QZD twice a day, whereas those in the control group were given 1 g of levocarnitine oral liquid twice a day. The two groups received the indicated medication for 12 weeks and were then followed up for 4 weeks. The primary outcome was sperm motility, and the secondary therapeutic indices were sperm volume, density, pregnancy probability, and CM syndrome score. The comparison between groups was carried out at 4, 8 and 12 weeks, respectively. The safety was determined before and after treatment. RESULTS: (1) Drop-off: 5 cases (7.58%) were lost after treatment (2 from the treatment group and 3 from the control group). (2) Primary outcomes: after 8- and 12-week treatment, the progressive sperms in the two groups were significantly higher than the baseline (all P<0.05); however, the treatment group showed greater improvement compared with the control group at 12-week treatment (22.7% ± 9.0% vs. 14.1% ±8.8%, P<0.05). The increasement of non-progressive grade sperms at both groups was observed at 8- and 12-week treatment with statistical difference (all P<0.05), however, the treatment group showed remarkable improvement compared with the control group at 12-week treatment (38.7% ±14.1% vs. 26.2% ±15.4%, P<0.05). (3) Secondary outcomes: no significant statistical differences were found in semen volume and density (4, 8, and 12-week treatment) and pregnancy probability of patients' wives (12-week treatment) between two groups (all P>0.05), however, the CM syndrome score of the treatment group significantly declined compared with baseline level at each time points (all P<0.05). (4) Safety: no obvious side reactions were found during the treatment in both groups. CONCLUSION QZD could improve the progressive and non-progressive grade sperm in the treatment of idiopathic asthenozoospermia. It is safe with no obvious side effects.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) improving pregnancy outcomes after surgery for endometriosis-associated infertility. METHODS: A multicenter, randomized, double-blind placebo parallel controlled clinical trial was designed. A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017, 101 patients in each group. The two groups received continuous intervention at 1-5 days after surgery, for 6 menstrual cycles. Before ovulation, the CM group was treated Huoxue Xiaoyi Granule (); after ovulation, Bushen Zhuyun Granule ( was involved. The control group was treated with placebo. Transvaginal ultrasonography was performed every menstrual cycle during the treatment, and female hormone levels in the follicular and luteal phases were measured during the 1st, 3rd and 6th menstrual cycles. The analysis was continued until pregnancy. The primary outcomes were clinical pregnancy rate and pregnancy outcome, and the secondary outcomes were follicular development and endometrial receptivity. Safety evaluations were performed before and after treatment. RESULTS: (1) Clinical pregnancy and live birth rates: the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group [44.6% (45/101) vs. 29.7% (30/101), 34.7% (35/101) vs. 20.8% (21/101), both P<0.05]. (2) Follicle development: the incidence of dominant follicles, rate of cumulative cycle ovulation, and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group [93.8% (350/373) vs. 89.5% (341/381), 80.4% (275/342) vs. 69.1% (253/366), 65.8% (181/275) vs 56.1% (142/253), P<0.05 or P<0.01]). The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group [11.7% (40/342) vs. 17.8% (65/366), P<0.05). (3) Endometrial receptivity: after treatment, both endometrial types and endometrial blood flow types in the CM group were mainly types A and B, while those in the placebo group were mainly types B and C, with a significant difference between the two groups (both P<0.05). (4) Adverse events: the incidence of adverse events between the two groups was not significantly different (P>0.05). CONCLUSION Strategies for activating blood circulation-regulating Gan (Liver)-tonifying Shen (Kidney) sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy, improve follicular development, promote ovulation, improve endometrial receptivity, while being a safe treatment option.

OBJECTIVE: Mandibular condyle injury usually results in malocclusion and disharmony of facial growth in growing children. This study aimed to evaluate the long-term effects of autogenous coronoid grafts on the facial growth of children with unilateral temporomandibular joint (TMJ) ankylosis who underwent mandibular condyle reconstruction. METHODS: Ten growing patients with unilateral bony TMJ ankylosis admitted in West China Hospital of Stomatology, Sichuan University between January 1st, 2008 and December 31st, 2016 were followed up and evaluated. These patients include three males and seven females with ages ranging from 5 years to 12 years at the time of surgery. Each patient underwent gap arthroplasty, condyle reconstruction with ipsilateral coronoid, and interposition of the pedicled temporalis fascial flap in a single operation. The postoperative follow-up ranged from 3 years to 8 years with an average of 4.9 years. Postoperative panoramic radiographs determined the growth of the mandibular height and length on the affected side and compared it with those of the healthy side. RESULTS: All patients recovered uneventfully after surgery. At the end of follow-up period, the maximal mouth opening ranged from 32 mm to 41 mm with an average of 35.6 mm. Mandibular height and length continued to grow after the successful treatment of ankylosis using autogenous coronoid grafts for condyle reconstruction. However, growth deficit still existed. The final ramus height and mandibular length of the affected side at the end of follow-up increased by 25.3% (P<0.05) and 26.1% (P<0.05), respectively, compared with the initial values measured immediately after surgery. Growth rates of ramus height and mandibular length of the affected side were 47.1% and 27.2% lower (P<0.05) than those of the healthy side, respectively. CONCLUSIONS Mandibular height and length continued to grow after the successful treatment of ankylosis by using autogenous coronoid grafts for condyle reconstruction. However, growth deficit still existed. The growth rate of the affected mandible was reduced compared with that of the undisturbed side even after treatment of ankylosis.

OBJECTIVE: To study the expression level of TGFβ1 and VEGF gene in patients with acute myeloid leukemia (AML) and its clinical prognostic value. METHODS: Seventy-eight AML patients treated in our hospital from July 2016 to September 2018 were selected. After isolation of bone marrow mononuclear cells from the patients, the levels of TGFβ1 and VEGF genes were detected by RT-PCR, and the correlation of TGFβ1 with VEGF genes and clinical characteristics of AML patients was analyzed. OS and EFS of the patients were evaluated by Kaplan-Meier, and Cox risk ratio model was used to analyze the prognostic risk factors of AML patients. RESULTS: The relative expression level of TGFβ1 gene in AML patients was 0.32±0.04, which was significantly lower than that in control group (P<005). The relative expression level of vascular endothelial growth factor(VEGF) gene in the patients was 2.65±0.15, which was significantly higher than that in the control group (P<0.05). The levels of TGFβ1 and VEGF genes significantly correlated with leukocyte count, hemoglobin, platelet and peripheral blast levels in AML patients (P<0.05). The level of TGFβ1 in AML patients with complete remission was higher than that in patients with partial remission or non-remission (P<0.05). The level of TGFβ1 in AML patients with partial remission was significantly higher than that in patients with non-remission (P<0.05). The level of VEGF in AML patients with complete remission was lower than at in patients with partial remission or non-remission (P<0.05). The level of VEGF in AML patients with partial remission was significantly lower than that in patients with non-remission (P<0.05). Kaplan-Meier survival analysis showed that OS and DFS in AML patients with high expression of TGFβ1 were better than those in patients with low expression of TGFβ1 (P<0.05), OS and DFS in AML patients with low expression of VEGF were better than those in patients with high expression of VEGF (P<0.05). Multivariate Cox regression analysis showed that platelet, TGFβ1 and VEGF gene were independent influencing factors of OS (P<0.05). Leukocyte, TGFβ1 and VEGF gene were independent influencing factors of DFS (P<0.05). CONCLUSION Decreased expression of TGFβ1 and increased expression of VEGF gene in AML patients closely relate to the poor prognosis of AML patients, which can provide reference for improving clinical efficacy of AML patients.

OBJECTIVE: To study the protective effect of asiaticoside against hyperoxia-induced bronchopulmonary dysplasia in neonatal rats based on the microRNA-155 (miR-155)/suppressor of cytokine signaling-1 (SOCS1) axis. METHODS: Neonatal rats were randomly divided into a control group, a model group, a low-dose asiaticoside group (10 mg/kg), a middle-dose asiaticoside group (25 mg/kg), a high-dose asiaticoside group (50 mg/kg), and a budesonide group (1.5 mg/kg), with 12 rats in each group. All rats except those in the control group were exposed to a high concentration of oxygen for 14 days to establish a neonatal rat model of bronchopulmonary dysplasia. The low-, middle-, and high-dose asiaticoside groups were given asiaticoside at different doses by gavage, and those in the budesonide group were given budesonide aerosol treatment. Hematoxylin and eosin staining was used to observe lung tissue development and measure radial alveolar count (RAC) and mean linear intercept (MLI). Superoxide dismutase (SOD) and malondialdehyde (MDA) detection kits were used to measure the levels of SOD and MDA in lung tissue. ELISA was used to measure the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Quantitative real-time PCR was used to measure the mRNA expression of miR-155 and SOCS1 in lung tissue. Western blotting was used to measure the protein expression of SOCS1 in lung tissue. RESULTS: Compared with the control group, the model group had the symptoms of bronchopulmonary dysplasia such as a disordered structure of lung tissue, enlargement of alveolar fusion, uneven alveolar septa, enlargement of average alveolar space, and a reduction in alveolar number. The model group also had significant increases in MLI, MDA level in lung tissue, serum levels of IL-6 and TNF-α, and miR-155 level in lung tissue (P<0.05) and significant reductions in RAC, SOD level, and mRNA and protein expression of SOCS1 in lung tissue (P<0.05). Compared with the model group, the low-, middle-, and high-dose asiaticoside groups and the budesonide group had significant improvement in the above symptoms of bronchopulmonary dysplasia, significant reductions in MLI, MDA level in lung tissue, serum levels of IL-6 and TNF-α, and miR-155 level in lung tissue (P<0.05), and significant increases in RAC, SOD level, and mRNA and protein expression of SOCS1 in lung tissue (P<0.05). Asiaticoside improved the above symptoms and indices in a dose-dependent manner. There were no significant differences in the above indices between the high-dose asiaticoside and budesonide groups (P>0.05). CONCLUSIONS Asiaticoside can alleviate inflammation injury induced by hyperoxia in neonatal rats and improve the symptoms of bronchopulmonary dysplasia in a dose-dependent manner, possibly by down-regulating the expression of miR-155 and up-regulating the expression of SOCS1.

OBJECTIVE: To study the effect and mechanism of action of irisin on hypoxic-ischemic brain damage in neonatal rats. METHODS: A total of 248 7-day-old Sprague-Dawley rats were randomly divided into a sham-operation group, a model group, and low- and high-dose irisin intervention groups (n=62 each). The rats in the model and irisin intervention groups were given hypoxic treatment after right common carotid artery ligation to establish a model of hypoxic-ischemic brain damage. Those in the sham-operation group were given the separation of the right common carotid artery without ligation or hypoxic treatment. The rats in the high- and low-dose irisin intervention groups were given intracerebroventricular injection of recombinant irisin polypeptide at a dose of 0.30 µg and 0.15 µg respectively. Those in the model and sham-operation groups were given the injection of an equal volume of PBS. The water maze test was used to compare neurological behaviors between groups. TTC staining, hematoxylin-eosin staining and TUNEL staining were used to observe histopathological changes of the brain. Western blot was used to measure the expression of the apoptosis-related molecules cleaved-caspase-3 (CC3), BCL-2 and BAX. RESULTS: Compared with the sham-operation group, the model group had a significant increase in latency time and a significant reduction in the number of platform crossings (P<0.05). Compared with the model group, the high-dose irisin intervention group had a significant reduction in latency time and a significant increase in the number of platform crossings (P<0.05). Compared with the sham-operation group, the model group had massive infarction in the right hemisphere, with significant increases in karyopyknosis and karyorrhexis. Compared with the model group, the high-dose irisin intervention group had a smaller infarct area of the right hemisphere, with reductions in karyopyknosis and karyorrhexis. The model group had a significantly higher apoptosis rate of cells in the right cerebral cortex and the hippocampus than the sham-operation group. The high-dose irisin intervention group had a significantly lower apoptosis rate than the model group (P<0.05). At 24 and 48 hours after modeling, the sham-operation group had a significantly lower level of CC3 than the model group (P<0.05). Compared with the model group, the high-dose irisin intervention group had a significantly lower level of CC3 and a significantly higher BCL-2/BAX ratio (P<0.05). The low-dose irisin intervention group had similar laboratory markers and histopathological changes of the brain to the model group. CONCLUSIONS Irisin can alleviate hypoxic-ischemic brain damage in neonatal rats in a dose-dependent manner, possibly by reducing cell apoptosis in the cerebral cortex and the hippocampus.

OBJECTIVE: To calculate the imbalance degree (IBD) of left-right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot meridians (IBD-HFM) of impedance in extracellular fluid of cells in twelve meridians of healthy subjects, so as to provide foundation for meridian diagnosis. METHODS: A total of 31 healthy volunteers were enrolled and bioelectrical impedance spectroscopy (BIS) was applied. The constant current (from 1 to 100 kHz, 200 μA) was connected into the bilateral twelve meridians through two excitation electrodes with a distance of 10 cm. Two measuring electrodes, with an interval of 5 cm, were set in between the two excitation electrodes to collect the voltage amplitude and phase. The Cole-Cole curve fitting was used to calculate the impedance of extracellular fluid of cells in the twelve meridians; the IBD-LRM, IBD-EIM and IBD-HFM as well as their absolute values were calculated. RESULTS: The impedance of extracellular fluid in the left side was higher than that in right side in the large intestine meridian, the small intestine meridian and the bladder meridian (<0.05, <0.01). The mean value of IBD-LRM of extracellular fluid was (4.0±1.4) %; the mean value of absolute value of IBD-LRM was (15.0±1.1) %; the maximum absolute value of IBD-LRM was the bladder meridian. The mean value of IBD-EIM was (3.3±1.0) %; the mean value of absolute value of IBD-EIM was (17.9±1.6) %; the maximum absolute value of IBD-EIM was the bladder meridian and the kidney meridian. The impedance of extracellular fluid of hand meridian, hand meridian and hand meridian were lower than those of foot meridians. The mean value of IBD-HFM was (-2.6±1.1) %; the mean value of absolute value of IBD-HFM was (19.7±1.7) %; the maximum absolute value of IBD-HFM was meridian; the imbalance of meridians was greater than meridians. There were significant differences in impedance of extracellular fluid between left and right and between hands and feet (<0.05, <0.01). CONCLUSION The extracellular fluid of left-right meridians of healthy subjects is different, but the absolute value of IBD is low; the mean value of exterior meridian and interior meridian is very close, and the absolute value of IBD is medium; the impedance of the foot meridians are greater than the hand meridians, and the absolute value of IBD is relatively high.
