Background and purpose:Cancer is a common disease. Multidisciplinary approach is the best model for cancer treatment. Cancer staging is the basis for diagnosis, treatments and prediction of prognosis.The survey is to give an overview of the current application of cancer multidisciplinary approach and UICC or other international cancer staging in mainland China. We made inquiries to our Chinese oncologists’ experience of using these staging and share their comments and recommendations. For those cancers common in China, Chinese oncologists and academic societies should provide more information of staging, therapies, outcome, prognostic predictors of prognosis, etc. to make international stage systems, like UICC or AJCC, a more appropriate, accurate and acceptable guide to individual patients’ staging and treatment, to predict outcome and to facilitate clinical trials better. Methods: This survey was done from 2012 to 2013 by questionnaires. The questions were answered for 10 major cancers in China (liver cancer, esophageal cancer, nasopharyngeal carcinoma, lung carcinoma, breast cancer, gastric cancer, colorectal cancer, gynecologic cancer, prostate cancer and lymphoma). Thirty-three questionnaires have been answered by national wide hospitals including provincial cancer hospitals, district cancer hospitals and departments of oncology in general hospitals. We also site visited 7 grade B hospitals. Results:Multidisciplinary approach is not widely used in the hospitals. UICC or AJCC stages have been widely used for 10 cancers, but for cancers that were uncommon in the West;while common in China (nasopharyngeal carcinoma, liver cancer) the staging proposed by Chinese society have also been used to replace UICC/AJCC. Conclusion:We suggest a wild implementation of multidisciplinary approach. For those cancers common in China Chinese oncologists and academic societies should provide more information of staging, therapies, outcome, prognostic predictors of prognosis etc. to make international stage systems, like UICC or AJCC, a more appropriate, accurate and acceptable guide to individual patients’ staging and treatments, to predict outcome and to facilitate clinical trials better.

Objective To analyze risk factors and antimicrobial use for hospital-acquired pneumonia (HAP)due to multidrug-resistant organisms (MDROs)in an intensive care unit(ICU),so as to perform risk assessment and guide antimicrobial use.Methods From January 2012 to December 2013,HAP patients were conducted retrospective co-hort study,risk factors for MDRO-HAP and rationality of antimicrobial use were analyzed.Results A total of 110 cases of HAP occurred in ICU,63 cases (57.27%)were MDR-HAP.Logistic regression analysis revealed that re-cent hospital stay ≥5 days (OR=19.94),transference from other hospitals (OR =19.33),infection type of late-onset HAP (OR=7.98),and antimicrobial use in recent 90 days (OR =3.42)were independent risk factors for MDR-HAP.Initial empirical anti-infective treatment revealed that there were no significant difference in timing of antimicrobial administration within 24 hours after clinical diagnosis was confirmed,and rationality of antimicrobial selection between MDR-HAP group and non-MDR-HAP group (both P >0.05);The isolation rate of pathogens in MDR-HAP group was lower than non-MDR-HAP group (73.02% vs 91 .49% P <0.05 ).Targeted antimicrobial therapy revealed that there were no significant difference in selection,dosage,and frequency of antimicrobial use be-tween two groups(all P >0.05 );the rationality rate of therapy course in MDR-HAP group was higher than no-MDR-HAP group,but rationality rate of combination use of antimicrobial agents was slightly lower than the latter (both P < 0.05 ).Conclusion Patients in ICU should be conducted risk factor assessment,and according prevention and control measures should be formulated,so as to reduce the occurrence of MDR-HAP,health care workers should standardized the initial empirical anti-infective treatment.

Objective To evaluate the effect of plan-do-check-act (PDCA)cycle method in improving disinfection efficacy of object surface in intensive care unit (ICU).Methods On the basis of management of healthcare-associat-ed infection (HAI)and prevention of multidrug-resistant organisms,disinfection efficacy of object surface in an ICU was intervened,data about surface object specimens taken before,during,and after intervention,HAI in patients, as well as detection of MDROs were collected.Results The total qualified rate of specimens taken before,during, and after intervention was 58.24%,76.74%,and 88.71 %,respectively,there was an increased tendency,the difference was significant (χ2 =17.41 ,P =0.009);the incidence of HAI was 3.72%,2.42%,and 1 .78%,respec-tively,there was a decreased tendency(χ2 =6.03,P =0.039),case infection rate was 4.36%,2.75%,and 2.37%respectively,there was a decreased tendency (χ2 = 7.24,P = 0.046 );detection rate of MDROs was 34.03%, 27.45%,and 14.05%,respectively,there was a decreased tendency (χ2 =33.84,P =0.007),the percentage of pa-tients who were detected MDROs and HAI caused by MDROs showed a decreased tendency(χ2 =6.14,6.02,both P<0.05).Conclusion The implementation of PDCA cycle can effectively improve disinfectant efficacy of ICU object surface,and reduce the incidence of MDRO HAI.

Purpose To detect the incidence rate, average age and the expression of hMLH-1 and hMSH-2 of sporadic colorectal carci-noma ( SCC) with Han and Uygur patients. Methods The expression of hMLH-1 and hMSH-2 was detected in SCC for 60 cases of Uygur and 196 cases of Han by immunohistochemical method, including 60 Uygur and Han cases normal colorectal mucosa ( NCM) . Results The positive rate of hMLH-1 and hMSH-2 proteins expression in the NCM was 100%. There was a marked difference in the positive rate of hMLH-1 in SCC between Han (93. 4%, 183/196)and Uygur (75%, 45/60) (P<0. 05). There was no significance in the positive rate of hMSH-2 in NCM between Han (94. 4%, 185/196) and Uygur (91. 7%, 55/60) (P>0. 05). The average age of Han and Uygur SCC patients were 65. 64 years, 57. 63 years, respectively, and Uygur SCC cases were more likely to be diagnosed at less 40 years old (P<0. 05). The positive rate of hMLH-1 and hMSH-2 expression in the tubular adenoma was 100%. The positive rate of hMLH-1 and hMSH-2 expression in the tubulovillous adenoma in Uygur and Han were 66. 7%( 2/3 ) and 66. 7%( 2/3 ) , and 74. 2%(23/31) and 90. 3%(28/31), respectively, significantly lower than those of tubular adenoma (P<0. 05). The expression of hMLH-1 was positively correlated with that of hMSH-2 in SCC in Han(rs =0. 737, P<0. 05). The expression of hMLH-1 was positive-ly correlated with that of hMSH-2 in SCC in Uygur(rs =0. 383, P<0. 05). There exists marked difference in the positive rate of hM-LH-1 and hMSH-2 among difference age groups (P<0. 05). Conclusion There is a certain loss of hMLH-1 and hMSH-2 expression in SCC in Han and Uygur Chinese, which is related to adenoma and age. The expression of hMLH-1 in SCC tissue among Uygur pa-tients is not resemble to those of Han patients. The average age of Uygur SCC patients is younger than Han, and the positive rate of hMLH-1 is higher. Combined detection of hMLH-1 and hMSH-2 proteins may be used for judging the severity and prognosis of SCC in Xinjiang, which helps improve patients’ treatment program and rationalize their choices.

Objective To investigate the therapeutic effect of the meso-cavo-atrial shunt (MCAS) in the treatment of combined Budd-Chiari syndrome (BCS). Methods The clinical data of 17 cases of combined BCS with all or bilateral hepatic vein occlusion and long range occlusion or obstruction of inferior vena cava (IVC) were admitted to the Qilu Hospital from February 2000 to May 2004. All patients were treated by MCAS with artificial blood vessels. The pre- and postoperative clinical symptoms, the IVC and portal venous (PV) pressures, the incidence of postoperative complications and the patency rate of the artificial vessels were analyzed. The survival of patients was analyzed using the Kaplan-Meier analysis, and the data were analyzed using the chi-square test and t test. Results No patient died during the perioperative period, and the symptoms of 15 patients disappeared or were relieved after operation, with a significant difference compared with those before operation (χ2 =9.78, P <0. 05 ). Three patients had complications after the operation. The postoperative PV and IVC pressures were decreased by 1.2 cm H2O (1 cm H2O =0.098 kPa) and 18.5 cm H2O, respectively. There were significant differences in the decrease of IVC and PV pressures ( t = 2.38, 3.06, P < 0.05 ). The 1-, 3-, 5-year survival rates were 16/17, 15/17 and 14/17, respectively, and the 5-year patency rate of the artificial vessels was 14/17.Conclusions MCAS can simultaneously relieve IVC and PV hypertension for patients with combined BCS. The postoperative complication rate was decreased, the 5-year survival rate and the patency rate of the artificial vessels were improved after the treatment, so MCAS is an optional surgical method for treating combined BCS.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

Objective To observe the changes of abdominal oxygen saturation in very low birth weight infants (VLBWI)with feeding intolerance (FI)within 1 4 days after birth monitored by near infrared spectroscopy (NIRS).Methods VLBWI fitting entry criteria were enrolled into this study.NIRS monitoring was carried out to detect cerebral oxygen saturation (ScO2 )and abdominal oxygen saturation (SsO2 ).Data were analyzed between FI infants and feeding tolerance (FT)infants.FI was defined as follows:gastric residual of more than 50% of the previous feeding volume;emesis or abdominal distention or both;decrease,delay or discontinuation of enteral feedings. Results 93 VLBWI were enrolled.52 cases(55.91 %)presented with FI,including 29 cases(31 .1 9%)of gastric residual increasing and 23 cases(24.73%)of emesis with or without abdominal distention within 1 4 days after birth. The levels of SsO2 and SsO2 /ScO2 showed no differences in infants with FT and with FI within 24h after birth (P >0.05).The change rates of the median of SsO2 and SsO2 /ScO2 in FT infants were similar during 1 4 days (P >0.05).While both the change rates of SsO2 and SsO2 /ScO2 were markedly decreased 1 day before and the day of FI (P <0.01 ).The decreasing degree of SsO2 was similar between infants with gastric residual increasing and infants with emesis with or without abdominal distention[(1 6.2 ±5.1 )vs (1 7.4 ±3.6)%,t =0.733,P =0.476]. Conclusion Abdominal oxygen saturation measured by NIRS may be a useful method for infants adjusting the feeding plan.

Objective To investigate the effects of supernatant of cultured mesangial vcells with serum IgA1 from [gA nephropathy patients on apoptosis of podocyte. Methods Jacalin affinity chromatography and Sephacryl S-200 molecular sieve chromatography were used to isolate IgA1. Apoptosis rate of podocyte was assessed by flow cytometer. Monomeric IgA1 (mIgA1) was transformed to aggregated IgA1(aIgA1) by heating. IgA-mesangial cell supernatant was prepared by collecting spent medium in which growth-arrested mesangial cells were incubated with different aIgA1, then the medium with RPMI 1640 containing 0.5%FBS was cultured with growth-arrested podocyte. Real time PCR was used to detect the mRNA expression of Bcl-2, Bax, Fas and Fas-L. Results Apoptosis rate of podocyte by supematant of cultured mesangial cell with algal from IgAN patients was higher than that from healthy and control groups [(28.5±5.9 ) % vs (22.5± 5.8)%, (20.5±4.5)%, all P<0.05]. Fas mRNA expression of podocyte exposed to supematant of cultured mesangial cells with aIgA1 from IgAN patients increased significantly and was 1.89 folds of control (P<0.05), while Bcl-2 mRNA expression significantly decreased and was 72% of control (P<0.05). The concentrations of Ang Ⅱ and TGF-β in supernatant of cultured mesangial cells with IgA1 from IgA nephropathy were significantly higher than those from healthy control [(13.2±3.4) ng/L vs (8.2±2.3) ng/L, /'<0.05; (15.4±3.4) ng/L vs (10.8±3.2) ng/L, P<0.05]. Conclusion Supernatant of cultured mesangial cells with IgA1 from IgA nephroapthy patients can induce apoptosis of podocyte, which may play a role in the progression of IgAN.
