OBJECTIVETo explore the effect of Shengjiang Xiexin Decoction (SXD) on the intestinal mucosal and functional cells of rats after irinotecan (CPT-11) chemotherapy.
METHODSTotally 24 healthy Sprague-Dawley (SD) male rats were divided into three groups, the normal control group, the CPT-11 group, the SXD combined CPT-11 group according to random digit table, 8 in each group. CPT-11 was injected at the daily dose of 150 mg/kg to rats in the CPT-11 group and the SXD combined CPT-11 group from the caudal vein on the 4th day, once daily for 2 successive days to duplicate delayed diarrhea model. Equal volume of normal saline was injected to rats in the normal control group from the caudal vein. SXD at 2 g/mL (10 g/kg body weight) was administered to rats in the SXD combined CPT-11 group by gastrogavage for 9 successive days. Deionized water was administered to rats in the CPT-11 group and the normal control group. Diarrhea was observed at 48, 60, 72, 84, 96, and 108 h to calculate the incidence rate of diarrhea. Meanwhile, scoring for diarrhea was performed by referring methods of Akinobu Kurita. Rats were killed on day 10, ileum, cecum, and colon tissues were collected and fixed in 10% formalin solution. HE staining was performed. Intestinal mucosa injuries were graded under light microscope according to the criterion of Chiu's score. The expressions of goblet cells and Paneth cells were observed by PAS stain. Enteroendocrine cells were observed by immunohistochemical CgA staining. Positive cells were counted and cumulative optical density (IOD) analyzed by Image-Pro-Plus 6.0.
RESULTSNo diarrhea occurred in rats of the normal control group at each time point. The incidence rate of diarrhea was 75.0% (6/8) at 48 h, 100.0% (8/8) at 60 h, 100.0% (8/8) at 72 h, 87.5% (7/8) at 84 h, 75.0% (6/8) at 96 h, and 75.0% (6/8) at 108 h in the CPT-11 group. The incidence rate of diarrhea was 25.0% (2/8) at 48 h, 50.0% (4/8) at 60 h, 12.5% (1/8) at 72 h, 0.0% (0/8) at 84 h in the SXD combined CPT-11 group. Compared with the same group at 60 h, scores for diarrhea at 48, 84, 96, and 108 h obviously decreased in the CPT-11 group, and scores for diarrhea at 48, 72, 84, 96, and 108 h obviously decreased in the SXD combined CPT-11 group (P < 0.05, P < 0.01). Compared with the same group at 72 h, scores for diarrhea at 84, 96, and 108 h obviously decreased in the CPT-11 group (P < 0.05, P < 0.01). Compared with the normal control group, scores for diarrhea increased in the CPT-11 group at each time point (P < 0.01); grading of ileum, cecum, and colon mucosal tissues increased (P < 0.05, P < 0.01); expressions of ileum and cecum mucosal epithelial goblet cells obviously decreased (P < 0.05); the number and expressions of ileum and cecum mucosal epithelial Paneth cells increased (P < 0.01). Expressions of ilium endocrine cells increased, while those of cecum and colon endocrine cells decreased in the CPT-11 group (P < 0.01). Compared with the CPT-11 group, scores for diarrhea were obviously lowered (P < 0.05, P < 0.01), grading of ileum, and cecum mucosal tissues decreased (P < 0.05, P < 0.01); expressions of ileum, cecum, and colon mucosal epithelial goblet cells obviously increased (P < 0.05, P < 0.01); the number and expressions of ileum cecum mucosal epithelial Paneth cells increased (P < 0.05); expressions of cecum and colon endocrine cells increased (P < 0.05, P < 0.01) in the SXD combined CPT-11 group.
CONCLUSIONSXD played roles in preventing and treating CPT-11 induced delayed diarrhea by improving CPT-11 chemotherapy induced apoptosis and necrosis of intestinal mucosal and functional cells.

Objective: To investigate the relationship between chemosensitivity to L-OHP and expressions of multidrug resistance (MDR) associated factors in lymph node metastases (LNMs) of gastric carcinoma. Methods: The chemosensitivity to L-OHP was measured by MIT assay, and the expressions of P-gp, GST-π, P53, Survivin and Bcl-2 were determined by immunohistochemistry in 54 paired primary tumor (PT) and LNMs of gastric carcinoma. Results: The inhibition rates of LNMs cells for L-OHP were lower than those of PT (P<0.05). The expressions of P-gp, GST-π and Bcl-2 were higher in LNMs than in PT (P<0.05), and no signifi-cant difference was found in the expression of P53 and Survivin between LNMs and PT (P>0.05). Positive cor-relations among P-gp, P53 and Bcl-2 were found in PT and LNMs (r=0.3424, 0.7123, 0.4548, P<0.05). There was no significant difference in the expression of GST-π and Survivin between PT and LNMs (P>0.05). There was statistically negative correlation between inhibition rates and expression of P-gp, GST-π, and Survivin in PT (P<0.05). In LNMs, only Survivin was negatively correlated with inhibition rates of L-OHP (P<0.05). Conclu-sion: The LNMs of gastric carcinoma are heterogeneous with PT in respect to chemosensitivity to L-OHP and expression of multidrug resistance associated factors. The main factors that affect chemosensitivity to L-OHP are also significantly different between PT and LNMs. Effective adjuvant chemotherapy after surgery and re-version to multidrug resistance (MDR) of gastric carcinoma depend on targeting the metastatic lesions of gas-tric carcinoma.

Objective: To investigate the changes of gene expression in CD34+ hematopoietic stem and progenitor cells (HSPCs) under different growth environments. Methods: Umbilical cord blood mononuclear cells (UCB MNCs) were cultured in static and stirred systems. After 7 days of culture, CD34+ cells were isolated and total RNA was extracted. Gene expression patterns of CD34+ cells from fresh, static and stirred cultures were compared using differential display (DD). Results: 30 gene fragments displayed differential expression levels based on the conditions of DD. One of differentially expressed genes was identified as RAN, which is a member of oncogene RAS family. This gene may be associated with proliferation of hematopoietic cells. Conclusion: Different growth environments induced differential gene expression patterns of CD34+ HSPCs. These differentially expressed genes would give new insights into optimizing in vitro environments for expanding hematopoietic cells.

Background and purpose:It was reported that zinc ifnger protein 139 (ZNF139) was expressed aberrantly in gastric cancer. But the relationship between ZNF139 and multidrug resistance (MDR) of gastric cancer is still not clear. The purpose of this research was to investigate the expressions and signiifcance of ZNF139, MRP-1, MDR1/P-gp, GST-π in human gastric carcinoma cell lines SGC7901 and SGC7901/ADR. Methods: The expressions of ZNF139, MRP-1, MDR1/P-gp, GST-πwere determined with RT-PCR and Western blot in SGC7901 and SGC7901/ADR cell lines. Then siRNA recombinant plasmid of targeting ZNF139 gene was constructed and imported into gastric cancer cell line SGC7901/ADR, and the expressions of MRP-1, MDR1/P-gp, GST-πwere tested simultaneously. Results:The expressions of ZNF139, MRP-1, MDR1/P-gp, GST-πwere higher in SGC7901/ADR than in SGC7901(P<0.05). ZNF139 was inhibited obviously after siRNA-ZNF139 was transfected into SGC7901/ADR, and expression of MRP-1, MDR1/P-gp, GST-πdecreased(P<0.05). Conclusion:ZNF139 may be invovled in multidrug resistance (MDR) of gastric cancer by up-regulating MRP-1, MDR1/P-gp and GST-π.

Objective To study the feasibility of using heat and moisture exchangers (HME)as an alternative to heated humidifiers (HH) in patients undergoing mechanical ventilation. Methods 266 pa-tients with mechanical ventilation admitted to our ICU over the recent 3 years were allocated to the experi-mental group (humidification with a heat and moisture exchanger) and the control group (with heated hu-midifier), and the effect of humidification, the reserved time of artificial airway, the time on mechanical yen-tilation, the time of stay in ICU, the ineidenee of ventilator-associated pneumonia (VAP) and the mor-tality rate were comparatively studied and analyzed. Results Significant differences were found between the experimental and the control group in effect of humidification, insufficiency of humidification or excessive hu-midification, airway spasm and time on mechanical ventilation and time of stay in ICU. The incidence of VAP in the control group was significantly higher than that in the experimental group. There were no significant dif-ference between the two groups in the reserved time of artificial airway and the mortality rate. There were no accident of humidification occurred in the experimental group while there were one case complicated with air-way burn and 11 eases complicated with choking with water in the control group. Conclusions We conclude that HH can be replaced by HME on mechanical ventilation while disease evolution and effect of humidification should be monitored closely and keep HME unobstructed.

OBJECTIVETo explore the feasibility and safety of radical mediastinal lymphadenectomy in thoracoscopic esophagectomy for esophageal cancer.
METHODSWe retrospectively analyzed the clinical data of a cohort of 147 patients with esophageal cancer who underwent thoracoscopic esophagectomy. Seventy-one patients received traditional lymphadenectomy for the periesophageal and subcarinal lymph nodes (traditional dissection group), while 76 patients received radical lymph node dissection for the bilateral recurrent laryngeal nerve lymphatic chains as well as the periesophageal and subcarinal nodes (radical dissection group). The number of retrieved lymph nodes, incidence of node metastasis, the operation time, estimated blood loss, complications, morbidity and mortality were compared between the two groups.
RESULTSThoracoscopic esophagectomy was completed in all patients with no conversion to thoracotomy. There were no significant differences of operational time and blood loss between the two groups [(89 ± 32) min versus (99 ± 32) min, P = 0.064; (152 ± 108) ml versus (107 ± 82) ml, P = 0.261]. In all patients, the total and average number of retrieved mediastinal nodes were 1644 and 11.2 ± 5.9/case, and the incidence of metastatic lymph nodes was 24.5%. The total and average number of retrieved mediastinal nodes were 999 and 13.6 ± 6.4/case in the radical dissection group, significantly higher than that in the traditional dissection group (645 and 9.1 ± 4.4/case) (P < 0.001). The average number of retrieved nodes and node metastasis rate in the radical dissection group were significantly higher than in the traditional dissection group (13.1 ± 6.4 versus 9.1 ± 4.4, P < 0.001; 35.5% versus 12.7%, P < 0.05). In the total group of 147 cases, the metastasis rates of periesophageal, subcarinal nodes and nodes along the recurrent laryngeal nerve lymphatic chains were 19.7%, 3.4% and 17.1%, respectively. There was thoracic lymph node metastasis in 27 cases with a metastasis rate of 35.5% in the radical dissection group, significantly higher than that in 9 cases and 12.7% in the traditional dissection group (P > 0.001). In the 1644 retrieved thoracic lymph nodes, there were 90 positive metastatic lymph nodes (metastasis ratio 5.5%). Among the 1644 lymph nodes, the metastasis ratio of periesophageal lymph nodes was 6.5%, subcarinal lymph modes 2.4% and the recurrent laryngeal nerve chain lymph nodes 7.5%. Among the 147 cases, complications occurred in 60 cases, with an overall morbidity rate of 40.8%. There were no significant differences of the incidence rates of overall complications, pulmonary complications and recurrent laryngeal nerve injury between the two groups (P > 0.05).
CONCLUSIONThoracoscopic esophagectomy with radical mediastinal lymphadenectomy is technically Safe and feasible.

Objective To research early pathological morphology and clinical significance of perforated duodenal ulcer (PDU) closed after non-surgical treatment. Methods Observed morphological changes of duodenal ulcer (DU) lesion with gastroscopy for 302 patients of PDU with non-surgical treatment in early period,when the perforation closed and measured up the clinical indicators during this hospitalization.Results There were 255 patients to be diagnosed with DU caused the perforation. These lesions were characteristic and shown the PDU closed at the bottom and the deep concave ulcers, except for 1 case which complicated by duodenal fistula. These ulcer types were diverse according to the time difference after treatment. No case of re-perforated ulcers or recurrence of peritonitis caused by gastroscopy. Conclusions Deep concave ulcer with A1 phase mainly is an early pathological manifestations of the DU after treated the PDU with non-surgical method characteristically. The wall of the closure of the serosal side is an original form closed perforated ulcer by non-surgical treatment. The risk of perforation associated with the following factors:( 1 )A single DU is located in the anterior wall region. (2)The shape of two kissing DU. (3)The diameter of DU ≥ 1.1 cm. In this case,early diagnosis by using endoscopy is a safe way.
