OBJECTIVETo explore the effect of moxibustion at Sanyinjiao (SP 6) on normal process of childbirth and safety of mothers and infants.

METHODSOne hundred and seventy-four cases of singleton primiparas, fetal head position were selected as the subjects and divided into three groups by single-blind randomized method: an acupoint group (n = 59), a non-acupoint group (n = 57) and a blank group (n = 58). When the cervix was dilated by 2 to 3 cm, DAJ-23 type multi-function moxibustion apparatus was used at Sanyinjiao (SP 6) in acupoint group, and at non-acupoint spot (the midpoint from the radial arterial pulse throbbing place on the radial side of the transverse crease of the wrist to the radial end of biceps tendon of the elbow) in non-acupoint group, 30 min for each one. The conventional labor care was adopted in blank group. The differences were observed in the first active stage, the second stage and the third stage of the labor as well as the safety of mothers and infants among three groups.

RESULTSThe durations of the first active stage of labor [(123.05 +/- 96.401) min] and the second stage [(37.407 +/- 22.390) min] in acupoint group were shorter than those [(171.40 +/- 94.339) min, (49.517 +/- 25.373) min] in non-acupoint group, as well as those [(178.79 +/- 97.231) min, (53.684 +/- 20.087) min] in blank group separately (all P < 0.05). It was discovered that the progressions of the first active stage and the second stage of labor were accelerated in acupoint group, and there was no statistically significant difference in the third stage of labor among the three groups (all P > 0.05). Bleeding amount after childbirth in acupoint group was less than those in non-acupoint group and blank group (both P < 0.05), and Apgar scores of newborns in acupoint group and non-acupoint group were higher than that in blank group (both P < 0.05).

CONCLUSIONMoxibustion at Sanyinjiao (SP 6) can shorten the process of childbirth, reduce postpartum bleeding and has no harmful impact on mothers and infants.

OBJECTIVETo observe the effects of Ganoderma lucidum spores on Cytochrome C (Cyt-C) and mitochondrial calcium in the testis of NIDDM rats.

METHODSFifty male Wistar rats were divided randomly into three groups: model, ganoderma and normal control, the first two groups injected with 2% STZ through vena caudalis, and the last one with half-and-half sodium citrate/citrate buffer solution. Two weeks after normal diet, glucose tolerance tests were performed and the rats with abnormal glucose tolerance from the model and ganoderma groups received high-fat and high-carbohydrate food, the ganoderma group given Ganoderma lucidum spores (250mg/[ kg x d] ) in addition, both for 10 weeks. Glucose tolerance tests were repeated 1 day before the end of the experiment and the rats were castrated and relevant indexes measured.

RESULTSThe NIDDM model was successfully constructed. In the model group, the levels of mitochondrial Cyt-C and mitochondrial calcium were significantly lower (P <0. 05) while that of the plasma Cyt-C was significantly higher than in the ganoderma and the control groups.

CONCLUSIONCyt-C and calcium ion are involved in the damage of the testis. Ganoderma lucidum spores can protect the testis of NIDDM rats.

OBJECTIVETo observe the effect of needling "Housanli" (ST 36) with different retaining-needle time on the pain threshold of mice using the hot water tail-flick test, and investigate the relationship between the retaining-needle time and the therapeutic effect.

METHODSTwenty-four healthy mice were randomly divided into four groups: no retaining-needle group (group A), retaining-needle 10 min group (group B), retaining-needle 20 min group (group C) and retaining-needle 30 min group (group D), with 6 mice for each group. After acupuncture "Housanli", the tail of mouse was put into the hot water at 50 degrees C, and the intervening time from the tail entered water to the tail flicked out of water was recorded and analyzed for each group.

RESULTSAfter acupuncturing "Housanli", the pain threshold was significantly improved with the hot water tail-flick test in both group A and group C (both P<0.01), however, there was no significant difference in both group B and group D (both P>0.05). Within 30 min of retaining-needle, the effect curve of acupuncture analgesia was showed in a waved line. In contrast, the maximum value of latent period on the tail-flick was detected in the group C that was the biggest effect of acupuncture analgesia among the four groups.

CONCLUSIONThe best retaining-needle time of hand-acupuncture for acupuncture analgesia is 20 min.

OBJECTIVETo investigate the function of apoptosis in esophageal cancer cells induced by soybean isoflavone, and the relation between this apoptosis and expression of bcl-2 and bax.

METHODSIn vitro experiments, MTT assay was used to determine the cell growth inhibitory rate. Transmission electron microscope and TUNEL staining method were used to quantitatively and qualitatively detect the apoptosis status of esophageal cancer cell line EC-9706 before and after the soybean isoflavone treatment. Immunohistochemical staining and reverse transcription-polymerase chain reaction were used to detect the expression of apoptosis-regulated gene bcl-2 and bax.

RESULTSSoybean isoflavone inhibited the growth of esophageal cancer cell line EC-9706 in a dose- and time-dependent manner. Soybean isoflavone induced EC-9706 cells to undergo apoptosis with typically apoptotic characteristics, including morphological changes of chromatin condensation, chromatin crescent formation, nucleus fragmentation and apoptotic body formation by transmission electron microscope and staining positive cells, using TUNEL assay. Soybean isoflavone reduced the expression of apoptosis-regulated gene bcl-2, and improving the expression of apoptosis-regulated gene bax.

CONCLUSIONSoybean isoflavone seemed to be able to induce the apoptosis in esophageal cancer. This type of apoptosis might be mediated by down-expression of apoptosis-regulated gene bcl-2 and up-expression of apoptosis-regulated gene bax.

The aim of this study is to investigate the critical factor affecting the properties of PLGA microspheres fabricated by a solid-in-oil-in-water (S/O/W) emulsion technique with BSA as a model protein. Prior to encapsulation, the BSA microparticles were fabricated by a modified freezing-induced phase separation method. The microparticles were subsequently encapsulated into PLGA microspheres by S/O/W emulsion method, then Motic BA200 biological microscope, confocal laser scanning microscope, scanning electron microscope were used to observe the structure of S/O/W emulsion and PLGA microspheres. The protein content extracted or released from BSA microspheres was measured by Bradford protein assay method. It was found that NaCl added in the outer aqueous phase effectively suppressed material exchange between the inner and outer phase of S/O/W emulsion. Then, the structure and permeability of obtained microspheres were influenced. As a result, with the increase of NaCl concentration in the outer aqueous phase, the encapsulation efficiency of microspheres significantly increased from 60% to more than 85%, the burst release of microspheres reduced from 70% to 20%, and the particle size decreased from 103 microm to 62 microm. Furthermore, the rehydration of encapsulated protein was also retarded and then integrity of BSA was successfully protected during encapsulation process. In vitro release test showed that BSA released from PLGA microspheres in a sustained manner for more than 30 days.

OBJECTIVETo measure levels of cytokines including IL-1β, IL-12, IL-18 and TNF-α in children with newly diagnosed type 1 diabetes and to analyze their correlation with clinical indices such as infection and onset time.

METHODSA total of 33 children with newly diagnosed type 1 diabetes were assigned to the case group, and 27 healthy children to the control group. The case group was further divided into increased white blood cell (WBC) and normal WBC subgroups according to peripheral WBC level. The serum levels of cytokines including IL-1β, IL-12, IL-18 and TNF-α were measured by enzyme-linked immunosorbent assay. Blood pH, blood sugar, blood lactate, fructosamine, peripheral leukocytes and neutrophils and some other clinical indices were also measured.

RESULTSThe level of IL-12 in the case group was higher than in the control group (P<0.001). In the case group, the level of IL-18 was negatively correlated with onset time (r=0.413, P=0.015), the neutrophil count was positively correlated with IL-1β level (r=0.413, P=0.023) and the WBC count was positively correlated with IL-18 level (r=0.352, P=0.038). IL-1β, IL-12 and IL-18 levels in the increased WBC subgroup were higher than in the normal WBC subgroup (P<0.05 for all comparisons).

CONCLUSIONSCytokine secretion disorders of Th1 cells exist in children with type 1 diabetes. Infections may induce cytokine secretion and might contribute to the early onset of diabetes.

BACKGROUNDThe gradually increasing changes in a human hyperlipidemic diet along with chronic stress might play an important role in the increased numbers of fatty liver. This study investigated the effects of Ilex asprella root decoction on related genes of lipid metabolism in chronic stress in hyperlipidemic fatty liver in rats.

METHODSForty-eight male Wistar rats were randomly divided into four groups: normal control group, model control group, simvastatin group, and Ilex asprella root group. To establish chronic stress and hyperlipidemic fatty liver models in rats, the levels of serum lipids, glucose, liver index, insulin (INS), insulin resistant (IR) index, adiponectin, superoxide dismutase (SOD), glutathione peroxidase (GSH-pX), glutathione (GSH), liver X receptor (LXR), and sterol responsive element binding protein (SREBP)-1c in rats were measured.

RESULTSWhen compared to the normal control group, the levels of serum lipids, glucose, liver index, INS, IR index, and GSH in the model control group significantly increased (P < 0.01). The protein levels of LXRα and SREBP-1c increased (P < 0.05), and the serum adiponectin and the SOD and GSH-pX decreased significantly (P < 0.01). When compared to the model control group, the levels of serum lipids, glucose, liver index, INS, IR index, SOD, and GSH-pX in the simvastatin group and Ilex asprella root group increased in varying degrees (P < 0.01 or 0.05); the serum adiponectin and GSH decreased (P < 0.05), while the protein levels of LXRα and SREBP-1c decreased in varying degrees (P < 0.01 or 0.05). When compared to the simvastatin group, the IR index and protein levels of LXRα in the Ilex asprella root group decreased (P < 0.05), and the serum adiponectin and SOD increased (P < 0.05).

CONCLUSIONThe Ilex asprella root decoction has some protective effects on regulating the related genes of lipid metabolism caused by chronic stress and hyperlipidemic fatty liver in rats.
