Irritable bowel syndrome(IBS)is one of the most common functional gastrointestinal disorders,which severely affects the life quality of patients. Currently,the pathogenesis of IBS has not yet been clarified. Visceral hypersensitivity and central algesia abnormality may be involved in the pathogenesis of IBS. Antidepressants can improve abdominal pain,abdominal discomfort,mental disorders and abnormal defecation and enhance the quality of life. This article reviewed the advances in study on antidepressants in treatment of IBS.

Objective To study the clinical outcomes of titanium-coated interbody fusion system in treating lumbar isthmic spondylolisthesis.Methods A retrospective study was made in 22 cases with lumbar isthmic spondylolisthesis including 15 with degree I spondylolisthesis and seven with degree II spondylolisthesis treated by posterior lumbar interbody fusion using titanium-coated fusion cages from June 2002 to December 2003 in our hospital.There were six males and 16 females,with age range of 41-68 years(mean 52.5 years).In all cases,double cages were implanted with additional posterolateral bone graft,supplemented with pedicle screw systems.The average preoperative and postoperative disc space height,foraminal height,segmental and lumbar lordosis,spondylolisthesis and domain of sagittal rotation on flexion-extension radiographs were measured and fusion state observed.The Oswestry disability index (ODI)was used to evaluate the clinical outcome.Results The fusion rate was 95.4%.There was significant recovery of disc space height,foraminal height and domain of sagittal rotation.ODI decreased significantly.Conclusion The anatomic titanium-coated fusion system is effective and safe in treatment of lumbar isthmic spondylolisthesis because it has advantages in restoring sagittal alignment and keeping bony endplate intact.

Objective To explore the clinical value and typing characteristic of prenatal ultrasonography for fetal cystic adenomatoid malformation of the lung(CAML).Methods Ultrasonographic features and typing of fetal CAML in 41 cases detected by prenatal ultrasonography were analyzed retrospectively.All cases were followed up until to the induction of labor or birth.Results (1)Site of tumor: in the 41 cases,there were 22 cases on the left side,15 on the right side and 4 on bilateral.(2)Typing diagnosis of prenatal ultrasonography: three cases were CAML type Ⅰ,14 were type Ⅱ,and 24 cases were type Ⅲ.(3)Pathology diagnosis: thirty two cases were induced abortion.CAML was confirmed in 29 cases by autopsy and the classifications were consistent with the prenatal diagnosis of ultrasonography.Three pulmonary sequestration cases were prenatally misdiagnosed as CAML type Ⅲ by ultrasonography.(4)The other nine cases were followed up to birth.Three masses decreased gradually and then disappeared.Six newborns were confirmed as CAML by CT.Their typings were consistent with the postnatal diagnosis.(5)The diagnostic accuracy rate of prenatal ultrasonography for CAML was 92.7%(38/41).Its misdiagnostic rate was 7.3%(3/41).Conclusions Prenatal ultrasonography has a high accuracy rate for the diagnosis and classification of CAML and is the first choice to detect CAML early in pregnancy.It has an important clinical value.Pulmonary sequestration should be distinguished from CAML type Ⅲ because they tend to be confused.

Objective To explore the change of apoptosis factor Caspase-3 and Bcl-2 in the injured segment of rat with spinal cord injury after inhibiting lentivirus expression of inflammation factor TNF-α. To study the relationship between Caspase-3, Bcl-2, Bax and TNF-α in spinal cord injury. Mthods Spinal cord contusion model was prepared by Allen method. The relation between tumor necrosis factor alpha and Bcl-2, was predicted by the method of GeneMANIA bioinformatics. The RNA which was packaged by lentivirus constructed the RNA interference model of tumour necrosis factor alpha. After interference of tumor necrosis factor alpha, we used the method of QRT-PCR to assays the mRNA expression of Caspase-3 and Bcl-2 in spinal cord and detect of the localization of Caspase-3 and Bcl-2 by immunohistochemistry. Statistical analysis with SPSS17.0. Results SD rats had paraplegia and urinate retentaion because of spinal cord injury. The result of QRT-PCR showed that in the seventh day after SCC, the expression of Caspase-3 reduced significantly (P < 0.05) and Bcl-2 did not change significantly (P > 0.05). Immunohistochemistry experiment results showed that Caspase-3 Bcl-2 and Bax immunoreactive cells were observed in the neurons and glial cells of both white matter and gray matter in the spinal cord. The results were the same with QRT-PCR.. Conclusion TNF-α in rats after SCC can effectively regulate the ratio of Bcl-2 and Bax , and then regulate the expression of Caspase-3 , which may affect the function of apoptosis and function recovery after spinal cord injury.

OBJECTIVEThere was consanguineous relationship between caspase-3 and early damage after hypoxia and ischemia. Caspase-3 plays a key role in the process of apoptosis in neuron. Magnesium sulfate could protect neuron from injuries, but the mechanism was not clear. The study was to investigate the expression of caspase-3 mRNA in the hippocampus of seven-day-old hypoxic-ischemic rats and the possible mechanism of neural protection with magnesium sulfate.

METHODSThe model of seven-day-old hypoxia-ischemia rats was established. The rats were divided randomly into 6 groups as follows: (1) normal control (n = 4); (2) sham surgery control (n = 4); (3) hypoxia-ischemia (n = 4); (4) sodium chloride injection with hypoxia-ischemia (n = 4); (5) magnesium sulfate pre-injection with hypoxia-ischemia (n = 4); (6)magnesium sulfate post-injection with hypoxia-ischemia (n = 4). The therapy groups received a bolus injection of 500 mg/kg magnesium sulfate intraperitoneally 0.5 hour before or after hypoxia-ischemia. Semi-quantitative RT-PCR was used to measure caspase-3 mRNA expression in the hippocampus 24 hours after hypoxia-ischemia.

RESULTSThe expression of caspase-3 mRNA was significantly increased in the hippocampus of the hypoxia-ischemia pups (1.88 +/- 0.36 vs 0.97 +/- 0.46, P < 0.05). The expression of caspase-3 mRNA in rats with magnesium sulfate pre-injection and post-injection decreased significantly (1.54 +/- 0.49, 1.65 +/- 0.48 vs 1.88 +/- 0.36, P < 0.05).

CONCLUSIONCaspase-3 was activated in the hippocampus of the seven-day-old rats 24 hours after hypoxia-ischemia. The suppression of the expression of caspase-3 mRNA in the hippocampus was probably related to the protective effect of magnesium sulfate on the brain injury of hypoxia-ischemia.

OBJECTIVETo establish a method for studying efficacious materials of traditional Chinese medicines from an overall perspective.

METHODCarthamus tinctorius was taken the example. Its major components were depleted by preparing liquid chromatography. Afterwards, the samples with major components depleted were evaluated for their antioxidant effect, so as to compare and analyze the major efficacious materials of C. tinctorius with antioxidant activity and the contributions.

RESULTSeven major components were depleted from C. tinctorius samples, and six of them were identified with MS data and control comparison. After all of the samples including depleted materials are compared and evaluated for their antioxidant effect, the findings showed that hydroxysafflor yellow A, anhydrosafflor yellow B and 6-hydroxykaempferol-3, 6-di-O-glucoside-7-O-glucuronide were the major efficacious materials.

CONCLUSIONThis study explored a novel and effective method for studying efficacious materials of traditional Chinese medicines. Through this method, we could explain the direct and indirect contributions of different components to the efficacy of traditional Chinese medicines, and make the efficacious material expression of traditional Chinese medicines clearer.
