[Objective] To search a noninjurious detecting method of progestin level for the evaluation of TCM combined with western medicine for infertility with ovarian dysfunction. [ Methods] Forty - two cases of infertility were treated with clomiphene citrate (CC), human menopausal gonadotropins (HMG) and CC combined with TCM respectively. Progestin levels in saliva and serum of the above cases in luteal phase were detected by radioimmunoassay method and were compared with those in 21 normal women. [Results] Saliva progestin level in luteal phase of the three treatment groups ranged from (294.0?1.5) pg/mL to (499.0 + 75.0) pg/mL, which was similar to that of the normal volunteers. And the matched serum progestin level in luteal phase of the three treatment groups ranged from (28.6 ?4.6) ng/mL to (51.4 ?16.6) ng/mL. After treatment, progestin levels in saliva and serum of pregnant cases in the treatment groups were higher than those of unpregnant, progestin levels in saliva and serum of pregnant cases in the treatment groups were higher than those of unpregnant cases ( P 0.05). [Conclusion] Detecting method of saliva progestin level is practical, effective and convenient and can be used as an alternative of serum progestin level detection. The effect of TCM is similar to that of CC and HMG.

Objective: To investigate the expression level of antisense transcript of pseudogene, general transcription factor Ⅱi psedugen23 (GTF2IP23), in breast cancer and its effect on the host gene general transcription factor Ⅱi (GTF2I). Methods: The expressions of GTF2IP23 and GTF2I were detected in 40 cases of invasive breast cancer tumors and their counterparts by using quantitative real-time polymerase chain reaction (qRT-PCR). The effects of GTF2IP23 on the expression of GTF2I gene and cell proliferation and migration were analyzed by overexpression of GTF2IP23 in breast cancer cells. Results: The expression of GTF2IP23 mRNA in breast cancer tissues was significantly higher than that in adjacent tissues (P<0.001), while the expression of GTF2I mRNA was significantly lower than that in adjacent tissues (P=0.007). The expression of GTF2IP23 was negatively correlated with GTF2I (r=-0.335, P=0.025). The expression of GTF2IP23 in breast cancer cells was significantly higher than in normal breast cells (P<0.01), while GTF2I expression in breast cancer cells was significantly lower than that in normal breast cells (P<0.01). Overexpression of GTF2IP23 in ZR-75-30 cells significantly reduced the expression of GTF2I (P=0.034) and enhanced cell proliferation (P=0.017) and migration (P=0.026) capacity. Conclusions GTF2IP23 is distinctly upregulated in breast cancer, it inhibits the expression of real gene GTF2I and promotes the proliferation of breast cancer cells.

This study investigated the role of long non-coding RNAs (lncRNAs) in the development of the palatal tissues. Cleft palates in mice were induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Expression levels of long non-coding RNA H19 (lncRNA H19) and insulin-like growth factor 2 (IGF2) gene were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The rate of occurrence of cleft palate was found to be 100% by TCDD exposure, and TCDD could cause short upper limb, cerebral fissure, webbed neck, and short neck. The expression levels of lncRNA H19 and IGF2 gene specifically showed embryo age-related differences on E13, E14, and E15 in the palatal tissues. The expression levels of lncRNA H19 and IGF2 gene showed an inverse relationship on E13, E14, and E15. These findings demonstrated that lncRNA H19 and IGF2 can mediate the development of mouse cleft palate.

Blastocystis hominis is a parasite that parasitizes in the intestines of humans and animals, and is closely related to a variety of gastrointestinal diseases such as abdominal pain and diarrhea. B. hominis is distributed worldwide, and the prevalence of B. hominis infections and dominant subgenotypes vary in countries and in regions from the same country. This paper reviews the global prevalence of B. hominis human infections, its subtypes and geographical distribution, so as to provide insights into the understanding of the global epidemiology of B. hominis and the management of B. hominis infections.

Blastocystis hominis is a common parasitic protozoa in human and animal intestines; however, its pathogenicity remains controversial. Construction of animal models is of great significance to investigate the pathogenicity, pathogenic mechanisms and drug screening of B. hominis. Experimental animals, mode of infections, parasite strains and host immune status are important factors affecting the successful modeling of B. hominis infections in animals. Hereby, we review the progress of researches on animal models of B. hominis infections, and summarize the influencing factors and application of animal models of B. hominis infections, in order to provides insights into the selection of animals models of B. hominis infections.

Objective: To observe the clinical efficacy of Jieyu Tongluo decoction on post-stroke depression (PSD) and its regulatory effect on neurotransmitter. Method: One hundred and twenty-five patients with PSD were randomly divided into control group (62 cases) and observation group (63 cases) by random number table. Both groups got psychological support, health education, and sertraline hydrochloride tablets, 25-50 mg/time, 2 times/days. Patients in control group got Shugan Jieyu capsules, 2 grains/time, 2 times/days. Patients in observation group got Jieyu Tongluo decoction, 1 dose/day. And a course of treatment was 6 weeks. Before and after treatment, hamilton depression scale (HAMD-17), patient health questionnaire-9 (PHQ-9), national institutes of health stroke scale (NHISS),traditional Chinese medicine(TCM) syndrome and activity of daily living scale (ADL) were scored. And levels of 5-serotonin (5-HT), norepinephrine (NE), dopamine (DA), brain-derived neurotrophic factor (BDNF), serum S100-β and neuron enolase (NES) were detected. Result: By rank sum test, after treatment, the clinical efficacy of observation group was superior to that in control group (Z=2.384, P<0.01). Scores of HAMD-17 and PHQ-9 were lower than those in control group (P<0.01). Score of HAMD-17 was lower than that in control group (Z=2.266, P<0.05), and score of PHQ-9 was lower than that in control group (Z=2.817, P<0.05). And scores of NHISS, TCM syndromes, serum S100 β and neuron enolase (NES) were lower than those in control group (P<0.01), while levels of ADL, 5-HT, DA, NE and BDNF were all higher than those in control group (P<0.01). Conclusion: In addition to psychotherapy and SSRI, Jieyu Tongluo decoction can relieve degree of depression, depressive symptoms and degree of neurologic impairment, increase activities of daily living, regulate neurotransmitter expression, and improve the reparation of cranial nerve tissue, with obvious clinical effects, and is worthy to be used in clinic.

Angelicae Sinensis Radix， derived from a medicinal and edible plant Angelica sinensis， is one of the traditional bulk Chinese medicines. In addition to gynecological blood stagnation and deficiency， its indications also include dysmenorrhea， deficiency and cold-induced abdominal pain， and rheumatoid arthritis. With the in-depth study of Angelicae Sinensis Radix， its anti-inflammatory and analgesic activities have attracted widespread attention. However， there has been no systemic report. The present study comprehensively reviewed the anti-inflammatory and analgesic activities of Angelicae Sinensis Radix （including its compositions， extracts， and different processed products） and mechanisms published in recent 30 years. The anti-inflammatory effect of Angelicae Sinensis Radix was achieved mainly by blocking the expression of proteins and genes in nuclear factor-κB （NF-κB）， mitogen-activated protein kinases （MAPK）， and Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathways， inhibiting the release of inflammatory mediators including tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， nitric oxide （NO）， prostaglandin E₂ （PGE₂） and IL-1β， and maintaining the high sensitivity of immune cells in the host to external stimuli. The mechanism of analgesic effect may be related to the suppression of the production of algesic substances （such as inflammatory factors and chemokines） or blocking of the amplification and transmission of pain perception in cascade reaction. Furthermore， the study also pointed out some problems in modern research and proposed suggestions on its future research to provide references for investigation and clinical applications of Angelicae Sinensis Radix.

OBJECTIVE: To investigate the causes of poor incision healing after total knee arthroplasty(TKA) and to propose active preventive and therapeutic measures. METHODS: Total 284 patients undergoing unilateral TKA from September 2016 to June 2018 were enrolled in the study and divided into control group and observation group. Firstly, 150 patients with unilateral TKA from September 2016 to June 2017 were retrospectively analyzed and included in the control group. There were 41 males and 109 females, with an average age of(63.5±7.2) years old. The causes of poor incision healing were discussed about patients themselves and surgical techniques. After analyzing, improvement measures were proposed. Total 134 patients with TKA from July 2017 to June 2018 were included in the observation group. There were 36 males and 98 females, with an average age of(62.4±8.9) years old. The patients in the observation group were treated with improved treatment strategies. RESULTS: Nine patients(6%) had poor incision healing in the control group and 1 patient (0.75%) had poor incision healing in the observation group. The incidence of poor incision healing was significantly different between the two groups (²=5.750, <0.01). CONCLUSIONS In order to prevent the poor incision healing after TKA, perioperative management and the operation techniques including stable, accurate, rapid and clean skills should be improved, leading to reduce the complications of incision and improve the recovery rate of patients.

[Objective] To investigate the impacts of voiding positions on urinary flow measurement (UFM) and post voided residual (PVR) in young males, to explore a better voiding position, and to provide reference for the clinical application of UFM. [Methods] A total of 43 male medical students (22-28 years old, all healthy with no lower urinary tract symptoms) from the First Affiliated Hospital of Xinxiang Medical College were enrolled.UFM was recorded in standing position, forward-bentding sitting position and sitting position, respectively.PVR was determined with B-ultrasound immediately after each voiding.Voided volume (VV), maximum urine flow rate (Qmax), average urine flow rate (Qave) and PVR were compared. [Results] In the standing, forward-bending sitting, and seating positions the VV were 211.6 (169.5, 265.9) mL, 206.8 (173.5, 262.8) mL, and 203.7 (175.9, 260.0) mL, respectively, with no significant difference (P=0.486); the Qmax were (26.00±2.33) mL/s, (26.41±2.12) mL/s, and (23.50±2.52) mL/s, respectively; the Qave were (14.03±2.21) mL/s, (14.27±2.18) mL/s, and (11.77±1.89) mL/s, respectively; the PVR were (9.97±2.26) mL, (9.43±1.97) mL and (12.10±3.28) mL, respectively.The Qmax and Qave in standing position and forward-bending sitting position were significantly higher than those in the sitting position, while the PVR was lower than that in the sitting position, with statistically significant difference (P<0.05). There were no significant differences in Qmax, Qave and PVR between the forward-bending sitting and standing positions (P>0.05). [Conclusion] Standing position and forward-bending seating position are beneficial for emptying the bladder, and these two positions are recommended for young men to urinate as the first choice.
