ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of bacterial lysates (OM-85BV) and all trans-retinoic acid (ATRA) on airway inflammation in asthmatic mice, and to investigate the immunoregulatory mechanism of OM-85BV and ATRA for airway inflammation in asthmatic mice.</p><p><b>METHODS</b>Forty female BALB/c mice were randomly divided into five groups: normal control, model, OM-85BV, ATRA, and OM-85BV+ATRA. A bronchial asthma model was established by intraperitoneal injection of ovalbumin (OVA) for sensitization and aerosol challenge in all mice except those in the normal control group. On days 25-34, before aerosol challenge, the model, OM-85BV, ATRA, and OM-85BV+ATRA groups were given normal saline, OM-85BV, ATRA, and OM-85BV+ATRA respectively by gavage. Normal saline was used instead for sensitization, challenge, and pretreatment before challenge in the normal control group. These mice were anesthetized and dissected at 24-48 hours after the final challenge. Bronchoalveolar lavage fluid (BALF) was collected from the right lung to measure the levels of interleukin-10 (IL-10) and interleukin-17 (IL-17) by ELISA. The left lung was collected to observe histopathological changes by hematoxylin-eosin staining. The relative expression of ROR-γT mRNA was measured by quantitative real-time PCR.</p><p><b>RESULTS</b>Compared with the normal control group, the model group showed contraction of the bronchial cavity, increased bronchial secretions, and a large number of infiltrating inflammatory cells around the bronchi and alveolar walls, as well as a significantly reduced level of IL-10 (P<0.05) and significantly increased levels of IL-17 and ROR-γT mRNA (P<0.05). Compared with the model group, the OM-85BV, ATRA, and OM-85BV+ATRA groups showed a significant reduction in infiltrating inflammatory cells around the bronchi and alveolar walls; the OM-85BV group showed a significant increase in the level of IL-10 in BALF (P<0.05) and significant reductions in the levels of IL-17 and ROR-γT mRNA (P<0.05); the ATRA group showed significant reductions in the levels of IL-17 and ROR-γT mRNA (P<0.05). Compared with the OM-85BV group, the OM-85BV+ATRA group had significantly increased relative expression of ROR-γT mRNA (P<0.05). Compared with the ATRA group, the OM-85BV+ATRA group had significantly increased levels of IL-10 and IL-17 in BALF (P<0.05).</p><p><b>CONCLUSIONS</b>Both OM-85BV and ATRA can reduce respiratory inflammation in asthmatic mice. However, a combination of the two drugs does not have a better effect than them used alone.</p>

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the possible influencing factors of pulmonary dysfunction in coal worker's pneumoconiosis (CWP).</p><p><b>METHODS</b>A total of 141 patients with CWP and 200 control miners with similar exposure histories but without apparent pulmonary disease or inflammation were interviewed with the detailed questionnaires (including histories of coal dust-exposure, smoking habits, alcohol consumption, protective mask uses, et al). Lung function examinations were performed at the same time. Predicted formula of lung function index were established by the local healthy residents characters and the pulmonary dysfunction was classified by the ratios between tested and predicted values.</p><p><b>RESULTS</b>All parameters of lung function were significantly lower in CWP cases when compared with that of control miners and the healthy controls (P < 0.05). The main types of pulmonary dysfunction were restrictive and mixed ventilation disorders in CWP patients. The factors such as the category of CWP, the mask worn, the smoking quantity and exposure to coal mine dust were included in the unconditional logistic regression model.</p><p><b>CONCLUSIONS</b>The category of CWP, the usage of mask, the smoking and long duration exposure to coal mine dust may be the main possible influencing factors of pulmonary dysfunction of CWP. Influencing factor analyses were given to inform choice of pertinence preventive measures.</p>

ABSTRACT
Objective To evaluate the efficacy of uterosacral ligament amputation in combination with lesion electrofulguration under laparoscope in the treatment of endometriosis-related dysmenorrhea. Methods A total of 86 patients with endometriosis-related dysmenorrhea were treated by uterosacral ligament amputation combined with electrofulguration of lesions under laparoscope from March 2000 to August 2004 in this hospital. Among the 86 patients, enucleation of ovarian endometriotic cysts and electrofulguration of pelvic endometriotic lesions were also simultaneously conducted in 37 patients, and electrofulguration of all visible pelvic endometriotic lesions was also performed in the rest of 49 patients. The operation was accomplished with the aid of the placement of an infrared ureteral detector in 3 patients because of the thickening of the uterosacral ligament and local adhesion. Results The 86 patients were followed for 6~48 months (median, 23 months). Dysmenorrheal completely disappeared in 36 patients, partially subsided in 29, and remained unchanged in 21, the effective rate being 75.6% (65/86). Conclusions Uterosacral ligament amputation combined with electrofulguration of lesions under laparoscope is effective for the treatment of endometriosis-related dysmenorrhea.
ABSTRACT
Objective To compare the therapeutic efficacy between laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty. Methods A total of 29 cases of congenital absence of vagina received either laparoscopic peritoneal vaginoplasty (Peritoneal Group, 14 cases) or sigmoid loop vaginoplasty (Sigmoid Group, 15 cases) from March 1998 to April 2003. Results The operation failed in 1 case in the Peritoneal Group, requiring a conversion to open sigmoid loop vaginoplasty. Both groups had no surgical complications or postoperative pyrexia. The operating time of the Peritoneal Group (118 9?19 0 min) was significantly shorter than that of the Sigmoid Group (202 0?18 6 min) ( t =-11 674, P =0 000). And the intraoperative blood loss of the former (36 2?12 6 ml) was significantly less than that of the latter (105 3?46 3 ml) ( t =-5 205, P =0 000). The conditions of reconstructed vagina of both groups were basically the same, but the vagina length of the Sigmoid Group (10 8?1 1 cm) was significantly greater than that of the Peritoneal Group (9 0?0 8 cm) ( t =-4 882, P =0 000). Among the Sigmoid Group, 3 cases had somewhat more amount of vaginal secretion and 4 cases had abnormal-smelling secretion. Patients in both groups reported the same satisfactory degree of sexual life. Conclusions Laparoscopic peritoneal vaginoplasty and sigmoid loop vaginoplasty present a similar therapeutic efficacy, but the former gives less surgical invasion than the latter.

Methods Clinical data of 21 cases of interstitial tubal pregnancy treated by laparoscopic operation were retrospectively studied. Results Operations in all the 21 cases were conducted successfully,without conversions to open surgery and intra- or post- operative complications.The operation time was 25 ～ 90 min (mean,40 min),and the postoperative hospital stay was 3 ～ 6 d (mean,4.5 d). Conclusions Laparoscopic operation for the treatment of interstitial tubal pregnancy is feasible.
ABSTRACT
Objective To investigate the feasibility of complicate myomectomy.Methods Six- seven patients with complicated uterine myomas undergoing laparoscopic myomectomy were retrospectively analyzed.The myomectomy was done using ureteral infravision imaging system or/and with self-made myoma segregate-stick.Among the total,there are 29 cases of multiple myomas(the number of myomas≥5)and 23 cases of single myoma(the diameter of myoma≥7cm,including 19 cases of intramural myoma,4 cases of subserous myoma),6 cases of myoma of broad ligament of uterus and 9 cases of cervical myoma.Results All cases were performed successfully laparoscopically.No intra-operative laparotomy or complications occurred.The average operating time and blood loss were(114?32)min and(114?78)ml respectively. The average time of hospital stay was 5.1 d.The average operating time and blood loss in the group (including multiple myoma group,intramural myoma group and cervical myoma)were significantly exceeded the other groups(including myoma of broad ligament of uterus group and subserous myoma group). Conclusions Laparoscopic complicate myomectomy can be performed and the operation indication is enlarged using Ureteral Infravision Imaging System.Advancement in surgical instruments and expert operating skills are the key to operation success.
ABSTRACT
s Objective To study the effect of HBV DNA of pregnant mothers on HBV intrauterine transmission. Methods Thirty one pairs of mothers and their newborn babies were detected for HBV by the HBV DNA qualitative PCR and HBV serology, as well as the concentration of HBV DNA in the blood by fluorescence quantitative PCR. Results There was a positive linear regression( r=0.5401, P=0.0017 ) between the concentration of HBV DNA in the infant and that in the mothers. Among the 31 infants, 19 showed abnormal by HBV DNA qualitative PCR and(or) HBV serology. It indicated that there was vertical transmission from the mothers to their infants. The transmission rate is 61%. The concentration of HBV DNA copies/ml(7.2?3.1) in mothers whose infants were abnormal was significantly higher than the others(5.8?1.3). Among the 31 mothers, 6 cases showed anti-HB positive and their babies were of much lower concentration of HBV DNA(4.2?1.8) than others(6.1?1.8). Conclusion The quantity of HBV in mothers reflected the strength of HBV vertical transmission and the chance of HBV transmission from mothers to infants have been decreased after mothers have obtained HbsAb.
