OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.

OBJECTIVETo explore the therapeutic effect of acupuncture combined with medication on continuing unovulation infertility.

METHODSFifty cases of continuing unovulation infertility were randomly divided into an observation group and a control group, 25 cases in each group. The observation group was treated with Chinese herbal decoction plus acupuncture. Culuanpao decoction, Cupailuan decoction and Cuhuangti decoction were respectively given according to different menstrual cycles and acupuncture and moxibustion at Guanyuan (CV 4), Zhongji (CV 3), Luanchao (ovary), etc. The control group was treated with oral administration of Clomiphene and intramuscular injection of Chorionic Gonadotropin. They were treated for 6 cycles and the ovulation rate and the pregnancy rate were observed.

RESULTSThere was no significant difference in the ovulation rate between the two groups (P > 0.05). The pregnancy rate of 44.0% in the observation group was significantly higher than 16.0% in the control group (P < 0.05). The observation group was superior to the control group in the score of mucus and the endometrial thickness.

CONCLUSIONBoth acupuncture combined with medication and oral administration of clomiphene plus intramuscular injection of chorionic gonadotropin have higher ovulation rate, and the former was higher than the latter in the pregnancy rate.

OBJECTIVETo study the effect of triangle drugs as ginseng, Trichosanthes kirilowii Maxim, and rhubarb on the levels of blood lipids as [total cholesterol (TC), triglyeride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)] and pro-inflammatory cytokines as intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and high sensitive C reactive protein (hs-CRP) during the process of treating atherosclerosis.

METHODSTwenty New Zealand rabbits were randomly divided into three groups after one-week adaptive feeding, i.e., the normal control group (n=6), the model group (n=6), and the triangle drugs group (n=8). High fat diet was fed to rabbits in the triangle drugs group and the model group at the daily dose of 100 g for six weeks. Iliac artery was injured in the model group and the triangle drugs group at the seventh week using balloon injury. High fat diet was successively fed to those after surgery for six weeks. At the same time of modeling, preventive medication (at the daily dose of dry ginseng 0.64 g/kg, Trichosanthes kirilowii Maxim 2.14 g/kg, and prepared Radix et Rhizoma Rhei with wine 0.43 g/kg, with the volume of 2 mL/kg) was administered by gastrogavage to rabbits in the triangle drugs group. Changes of blood lipids levels and related pro-inflammatory cytokines were dynamically observed.

RESULTSOn the 7th week (before surgery), the levels of TC, TG, HDL-C, and LDL-C in the model group, TC, HDL-C, and LDL-C in the triangle drugs group significantly increased, showing significant difference when compared with those of the normal control group (P < 0.05). The levels of pro-inflammatory cytokines in the model group and the triangle drugs group were significantly higher than those in the normal control group (P < 0.05). Levels of TC, TG, and LDL-C were lower in the triangle drugs group than in the model group, showing statistical difference (P < 0.05). After the 8th week the levels of blood lipids and ICAM-1 in the model group, and levels of TC, LDL-C, HDL-C, and ICAM-1 in the triangle drugs group were significantly higher than those of the normal control group, showing statistical difference (P < 0.05). After the 12th week levels of blood lipids in the model group, LDL-C and HDL-C in the triangle drugs group were significantly higher than those of the normal control group, showing statistical difference (P < 0.05). The LDL-C level was lower in the triangle drugs group than in the model group, showing statistical difference (P < 0.05). The levels of VCAM-1, ICAM-1, and hs-CRP in the model group were obviously higher than those in the triangle drugs group and the normal control group, showing statistical significance (P < 0.05). The hs-CRP level was higher in the triangle drugs group than in the normal control group, showing statistical difference (P < 0.05).

CONCLUSIONSThe triangle drugs may postpone the process of atherosclerosis by lowering blood lipids levels, especially by lowering the elevating levels of TC and LDL-C. Its roles in decreasing the level of pro-inflammatory cytokines might be associated with lipids lowering and anti-inflammation. Its roles may also be associated with improvement of the endothelial function and inhibition of the smooth muscle proliferation.

Objective To observe the state of endemic flurosis in Qinghai province in 2008 and to provide scientific basis for endemic flurosis control and prevention. Methods All the endemic fluorosis villages in Qinghai province was divided into slight,medium and heavy degree according to the water fluoride content before improving water,and 2,4,4 villages were collected from each degree,respectively. Water samples were collected from each direction of east,west,south,north and centre,and fluoride concentration were determined from each surveyed villages with unimproved-water. At the same time,3 copies of the peripheral water samples and a sample of source water were collected to determine fluoride concentration. In all the village children aged 8 to 12 were tested for dental fluorosis by Dean method. Six copies of the urinary fluoride were randomly sampled in different age groups. The fluorine content in urine was determined with F-ion selective electrode. The situation of clinical skeletal fluorosis of adults over 16 years of age was examined,and 20 adults in the villages of medium and heavy levels were filmed for skeletal fluorosis. Results The detectable rate of dental fluorosis of children aged 8-12 years old was 43.59% (245/562),that of skeletal flurosis of adults aged above 16 years was 50.32% (1582/3144) and detectable rate of X-ray was 29.45% (48/163). Fluoride content in urine was 1.52 mg/L. Conclusions Endemic fluorosis is still very serious in Qiaghai province in a rising trend,so the control measures need to be strengthen.

The nucleotide sequence and N-, C-terminal amino acid sequences of alpha,beta-subunit of glutaryl 7-ACA acylase C130 from Pseudomonas sp. 130 were determined. The alignment of the acylase C130 with the other acylases shows that it has high homology with the acylases from Pseudomonas sp. GK16 and C427, but low homology with the others. There is large difference in the N-terminal of alpha-subunit, while the N-terminal of beta-subunit has significant conservation.

In this paper, the author systematically summarized and explained the idea of Prof. JIANG Liang-duo for preventing and treating the coronavirus disease-2019(COVID-19). According to Prof. JIANG, in the early stage of the disease, dampness and heat injury to the lung is the main cause and pathogenesis, and the high-risk group can be protected by supplementing Qi and nourishing Yin, clearing away heat and penetration. The patients with mild disease can be treated with Chinese medicine. But the accurately treatment can be given only knowing the ratio of the dampness, heat, deficiency and excess. For the patients with severe disease, both strengthening and removing pathogenic factors are important. But the drug for Qi should be prescribed instead of drugs for blood. The prognosis of critical illed patients is very poor, and the method of Invigorating Qi and taking Jin is useful to strengthen the foundation, promot lung, remove dampness, clear heat and cool Ying. Clinical medication should be adjusted according to people, time and place in the different situations.

Objective: To explore the effect of down-regulation of retinol binding protein 2 (RBP2) expression on the biological characteristics of ovarian cancer cells and its mechanism. Methods: Knockdown of RBP2 and cisplatin (DDP)-resistant ovarian cancer cell line SKOV3/DDP-RBP2i was established, the negative control group and blank control group were also set. Cell counting kit 8 (CCK-8) was used to detect the cell proliferation ability, flow cytometry was used to detect cell apoptosis, scratch test and Transwell invasion test were used to detect cell migration and invasion ability, real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) and western blot were used to detect the expressions of molecular markers related to epithelial-mesenchymal transition (EMT). The effect of RBP2 on the growth of ovarian cancer was verified through experiment of transplanted tumors in nude mice, and the relationships between RBP2 expression and tumor metastasis and patient prognosis were analyzed using the clinical data of ovarian cancer in TCGA database. Results: After down-regulating the expression of RBP2, the proliferation ability of SKOV3/DDP cell was significantly reduced. On the fifth day, the proliferation activities of SKOV3/DDP-RBP2i group, negative control group and blank control group were (56.67±4.16)%, (84.67±3.51) and (87.00±4.00)% respectively, with statistically significant difference (P<0.001). The apoptosis rate of SKOV3/DDP-RBP2i group was (14.19±1.50)%, higher than (8.77±0.75)% of the negative control group and (7.48±0.52)% of the blank control group (P<0.001). The number of invasive cells of SKOV3/DDP-RBP2i group was (55.20±2.39), lower than (82.60±5.18) and (80.80±7.26) of the negative control group and the blank control group, respectively (P<0.001). The scratch healing rate of SKOV3/DDP-RBP2i group was (28.47±2.72)%, lower than (50.58±4.06)% and (48.92±4.63)% of the negative control group and the blank control group, respectively (P<0.001). The mRNA and protein expressions of E-cadherin in the SKOV3/DDP-RBP2i group were higher than those in the negative control group (P=0.015, P<0.001) and the blank control group (P=0.006, P<0.001). The mRNA and protein expression of N-cadherin in SKOV3/DDP-RBP2i group were lower than those in the negative control group (P=0.012, P<0.001) and the blank control group (P=0.005, P<0.001). The mRNA and protein expressions of vimentin in SKOV3/DDP-RBP2i group were also lower than those in the negative control group (P=0.016, P=0.001) and the blank control group (P=0.011, P=0.001). Five weeks after the cells inoculated into the nude mice, the tumor volume of SKOV3/DDP-RBP2i group, negative control group and blank control group were statistically significant different. The tumor volume of SKOV3/DDP-RBP2i group was smaller than those of negative control group and blank control group (P=0.001). Bioinformatics analysis showed that the expression of RBP2 in patients with metastatic ovarian cancer was higher than that without metastasis (P=0.043), and the median overall survival of ovarian cancer patients with high RBP2 expression was 41 months, shorter than 69 months of low RBP2 expression patients (P<0.001). Conclusion: Downregulation of the expression of RBP2 in SKOV3/DDP cells can inhibit cell migration and invasion, and the mechanism may be related to the inhibition of EMT.
