OBJECTIVE: Yun Kang oral liquid is a listed proprietary Chinese Medicine. To further evaluate its efficacy, this experiment established a kidney deficiency and luteum inhibition threatened abortion rat model to observe the effects of Yun Kang oral liquid. METHODS: Sixty pregnant rats were randomly divided into normal control group (NC), model group (MG), dydrogesterone group (DT, 3.02 mg/kg), and Yun Kang oral liquid low-dose group (YK-L, 4 ml/kg), medium dose group (YK-M, 6 ml/kg), high dose group (YK-H, 9 ml/kg), 10 in each group. On the first day of pregnancy, each administration group was treated with the test drug at the prescribed dose every morning, and the NC group and the MG group were given an equal volume of purified water for 10 days; the rats were intragastrically administrated every afternoon, except for the NC group. In addition, the other groups were intragastrically administered with hydroxyurea at a dose of 450 mg/kg for 9 days, and mifepristone was administered at a dose of 4.0 mg/kg on the 10th day. On the 9th day of pregnancy, behavioral signs such as back temperature, grasping force, pain threshold, and autonomic activity were measured in each group. On the 11th day of pregnancy, blood was collected from the abdominal aorta in each group to determine serum levels of estradiol (E) , progesterone (P) and thromboxane B (TXB) . Ovary and fetal uterus were removed, the number and diameter of embryos were observed, and the ovary and uterus indexes were calculated. RESULTS: Compared with the NC group, the back temperature, grip, pain threshold, number of spontaneous activities, number of embryos, embryo diameter, uterus index and serum E, P, TXB levels in the MG group were decreased significantly (P＜0.05, 0.01). Compared with the MG group, the back temperature, grasping force, number of embryos, embryo diameter and serum E and P levels were increased significantly in each dose group (P＜0.05, 0.01); the pain threshold, autonomic activity, and uterus index of YK-M and YK-H group were increased significantly (P＜0.05); serum level of TXB in YK-H group were increased significantly (P＜0.05). CONCLUSION Yun Kang oral liquid has a clear kidney-filling effect on rats with threatened abortion caused by kidney deficiency-luteal suppression. The mechanism may be related to raising serum E, P, TXB levels, improving kidney deficiency and improving embryo quality.

In this study, the effects of high-intensity-focused ultrasound (HIFU) treatment on benign uterine tumor patients were examined. A total of 333 patients diagnosed with fibroids or adenomyosis using diagnostic sonography, treated with HIFU between February 4, 2010 and December 29, 2014 at a hospital in Korea, and followed up for three or six months were selected for this study. Their benign uterine tumor volume was measured, and the effects of HIFU treatment on the volume were analyzed according to age, disease, fertility, and treatment duration. The volume of benign tumors of the uterus changed by age in all age groups after conducting HIFU treatment for 3 and 6 months, respectively. The rate of decrease in individuals' in their twenties was the largest, at 64.9%. When the decreasing volume of benign tumors of the uterus was analyzed by type of disease, the treatment efficacy for adenomyosis was the best, with a decrease of 164.83 cm3 after 6 months. Myoma had the fastest decreasing rate, at 68.5%. When evaluated on the basis of fertility, the volume of benign tumors of the uterus continued to decrease until 6 months after completing all procedures. The volume has continued to decrease for 6 months after all procedures. This study showed that HIFU treatments for uterine fibroid and adenomyosis is an effective non-invasive therapy via reducing the benign uterine tumor volume. Therefore, the HIFU method might replace other conventional treatment methods.

The uterine tetanic contraction and uterine artery blood flow reduction are possible reasons for primary dysmenorrhea (PD). In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction (GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F2 alpha (PGF2α) and Ca(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF2α and Ca(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

OBJECTIVETo evaluate the roles or effects of oviductus ranae (OR) or oviductus ranae eggs (ORE) in preventing and treating postmenopausal osteoporosis.

METHODSIn vivo experiment: Sixty female adult Wistar rats were randomly divided into 5 groups of 12. To provide an osteoporosis model 4 groups of rats were ovariectomized (OVX), with the 5th being sham operated. Medication commenced 7 days after the operation and lasted continuously for 12 weeks. Sham operated and OVX groups were given equivalent volumes of 5% Tween-80. The other three groups intragastrically received conjugated estrogens (CE), OR or ORE of the corresponding doses. At the 12th week, serum estrogen, bone gla protein (BGP), serum calcium, phosphorus, and alkaline phosphatase (ALP) were assayed; bone mineral densities (BMD) were measured and bone scanning was conducted; uteri were weighed, and weight, volume and length of the femoral bones were determined; and cortical thickness of femoral heads and area of bone trabecula were measured by image analyzer. In vitro experiment: Eighty 10-month old SD rats, with equal numbers of males and females, were randomly divided into 8 groups. Osteoblasts were isolated from neonatal rat calvariae, and the cells were exposed to various concentrations of serum from OR and ORE groups to study the impact of these sera on osteoblastic proliferation, ALP activity and mineralization. Osteoclastic numbers were determined using tartrate resistant acid phosphatase (TRAP).

RESULTSIn vivo experiment: The body weight of the four OVX groups increased significantly (P<0.01). Uterine weight of the CE group was the highest (P<0.01); Compared with the model group, estrogen level, BMD, bone scanning/bone imaging index weight of the femoral bones, cortical thickness of femoral heads in the OR and ORE groups increased significantly (P<0.05, P<0.01); femoral volume in the ORE group increased significantly (P<0.05); and the content of osteocalcin, phosphorus, and ALP in serum decreased significantly (P<0.05, P<0.01). In vitro experiment: Sera from OR and ORE groups had notable effects on the proliferation of osteoblasts (P<0.05 and P<0.01, repsectively) and stimulated the formation of calcium nodes (P<0.05, P<0.01), while the enhancement of ALP activity in osteoblasts was significant (P<0.05, P<0.01). The number of TRAP-positive cells was significantly reduced as well (P<0.01).

CONCLUSIONSOR and its eggs could effectively suppress OVX-induced osteoporosis in rats, and increase bone turnover possibly by both an increase in osteoblastic activity and a decrease in osteoclastic activity. The present study provides evidence that OR and its eggs could be considered a complementary and alternative medicine for the treatment of postmenopausal osteoporosis.

OBJECTIVETo investigate the preventive effects and possible underlying mechanism of different extracts of Kanggushu () on osteoporosis in ovariectomized rats.

METHODSOne hundred and sixtyfive female SD rats were divided into 11 groups: control, sham, model, Xianling Gubao Capsule (), nilestriol, Kanggushu aqueous extract high-, medium-, and low-dose and suet extract high-, medium-, and low-dose groups. The osteoporosis model was made by ovariectomizing the rats. The latter 8 groups were administered intragastricly with Xianling Gubao Capsule, nilestriol, Kanggushu aqueous extract and suet extract for 12 weeks, respectively, while the other 3 groups were administered orally saline. The whole body bone mineral density, bone mineral content, organ coefficient of uterus, serum estradiol and alkaline phosphatase contents, blood calcium, phosphorus, interleukin 6 and bone Gla-protein levels after treatment were monitored. Additionally, three-point bending test of femur, HE staining, and scanning electron microscope were performed to explore the pharmacodynamics and underlying mechanisms.

RESULTSIn comparison with ovariectomized rats of model group, Kanggushu aqueous extract high-dose resulted in an increased bone mineral density, bone mineral content and organ coefficient of uterus, improved estradiol level, and improved maximum load and structural stiffness (P<0.05 or P<0.01). Two-dimensional and three-dimensional trabecular structure was also observed under HE staining and scanning electron microscopy, and the number and thickness of trabecular bone in Kanggushu aqueous extract high-dose group was significantly increased compared to the model group, while the lipid droplets in bone marrow cavity were significantly less. However, there were no significant differences in blood calcium, total serum alkaline phosphatase and bone Gla protein among different treatment groups. Overall, the osteoprotective effects of Kanggushu aqueous extract were comparable to those of nilestriol and were significantly more effective than those of Xianling Gubao Capsule.

CONCLUSIONThe preventive effects of Kanggushu aqueous extract might be partly due to the increased estradiol level, accelerated restoration of bone trabecular reticulate structure, and accordingly increased bone mineral density in osteoporosis rats.

OBJECTIVETo observe the curative effect of massage in the treatment of primary dysmenorrhea (PD), and its effect on hemodynamics parameters of uterine artery and serum prostaglandins.

METHODS60 PD patients were randomly assigned to the massage group and the control group, 30 in each. Patients in the massage group received massage, while those in the control group orally took ibuprofen sustained release capsule, both for three menstrual cycles. The pain degree was assessed using visual analogue scale (VAS). The hemodynamics parameters of uterine artery [including pulsatility index (PI), resistance index (RI), systolic to diastolic peak ratio (S/D)], the serum levels of prostaglandin F2alpha (PGF2alpha) and PGE2 in the menstruation were detected in the two groups before and after treatment.

RESULTSThere was no statistical difference in each index before treatment between the two groups (P>0.05). Compared with the control group after treatment, the scores of VAS (mm, 33. 17+/-7.93 vs 63.53+/-9.48), PI (2.18+/-0.18 vs 2.74+/-0.23), RI (0.67+/-0.09 vs 0. 86+/-0.27), S/D (5.44+/-0.47 vs 7.56+/-0.28), and serum PGF2a level (ng/L, 28. 10+/-2.41 vs 37.68+/-2.16) were lower and serum PGE, level (ng/L, 29.82+/-2.13 vs 26.43+/-1.42) higher in the massage group, showing statistical difference (P<0.05, P<0.01).

CONCLUSIONSMassage had favorable therapeutic effect on PD. Its effect might be achieved through improving the blood circulation of uterus, adjusting the abnormal levels of PGF2a and PGE2, thus exerting pain relief effect.
