OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

Objective To study the method and clinical value of preservation of intercostobrachial nerve( ICBN) by fat dissolving meth-od during breast cancer operation. Methods The clinical data of 50 cases withⅠ~Ⅲa stage breast cancer from January 2013 to June 2013 were analyzed. Fifty patients were randomly divided into two groups,there were 26 patients in preservation group,whose ICBN were preserved by fat dissolving method during axillary lymph nodes dissection,and 24 patients in resection group,whose ICBN were not preserved by routine method during axillary lymph nodes dissection. Comparison of operation times,bleeding volume,the number of axillary lymph nodes dissection and upper arm sensory function of patients after operation between both groups was done. Results The mean time of operation was (102. 3 ± 15. 6) min in preservation group and(95. 6 ± 12. 4) min in resection group,while the number of axillary lymph nodes dissection was (19. 5 ± 8. 8 ) in preservation group and ( 19. 2 ± 9. 5 ) in resection group, with no significant difference between both groups (P>0. 05). Bleeding volume was (51. 2 ± 11. 5)mL in preservation group and (98. 5 ± 13. 4)mL in resection group,with significant differ-ences(P<0. 05). After postoperative one month,we observed upper arm sensory function of patients. It showed that 3 cases of sensory numb-ness or pain occurred in preservation group (11. 5%),20 cases of sensory abnormality occurred in resection group (83. 3%),mainly as sen-sory loss,numbness,pain or burning sensation,there was significant difference between both groups (P<0. 05). All patients were followed up half a year,patients with sensory abnormality in preservation group recovered,and recovery in resection group was not obvious,it still showed sensory abnormality in varying degrees. During the follow-up,no local recurrence or distant metastasis was found in both groups. Conclusion Preserving intercostobrachial nerve by fat dissolving method in breast cancer operation is based on conventional operation and made a few of improvements. It is simple and feasible. During the operation,we find that the axillary neurovascular is clearer,preservation of ICBN is easier. It does not affect the axillary lymph node dissection and operation time,while it can reduce incidence of postoperative sensory abnormality and improve the quality of life of patients,therefore it is worthy of clinical application.

Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

OBJECTIVETo study the effect of acupuncture on the immune function of sepsis patients.

METHODSNinety sepsis patients were assigned to the control group, the thymosin a1 group, and the acupuncture treatment group according to random digit table, 30 patients in each group. Patients in the control group were treated according to the guideline of Surviving Sepsis Campaign (SSC). Patients in the control group received routine treatment. Those in the thymosin alpha1 group additionally received subdermal injection of thymosin alpha1 (1.6 mg), once per day for 6 successive days. Needling at related points such as Zusanli (ST36), Yanglingquan (GB34), Neiguan (PC6), Guanyuan (RN4), and so on, was performed in patients of the acupuncture treatment group, once per day for 6 successive days. T cell subgroups (CD3+, CD4+, CD8+, CD4+ /CD8+) and immunoglobulin levels (IgG, IgA, IgM) were detected. The length of ICU hospital stay, hospital readmission rate, and 28-day mortality were compared among the three groups.

RESULTSAfter six days of treatment, CD3+, CD4+, CD8+, IgG, IgA, IgM, and CD4+ /CD8+ ratio of three groups were all significantly increased (P < 0.01). Of them, CD3+, CD4+, CD8+, IgG, IgA, and IgM increased more significantly in the thymosin alpha1 group and the acupuncture treatment group (P < 0.01). Compared with the control group, the ICU hospitalization length was significantly shortened, the hospital readmission rate and the 28-day mortality were lower in the thymosin alpha1 group and the acupuncture treatment group (P < 0.05, P < 0.01). There was no statistical difference in each index between the thymosin alpha1 group and the acupuncture treatment group (P > 0.05).

CONCLUSIONAcupuncture could adjust the immune function of sepsis patients, improve their immunological indicators and prognoses.

OBJECTIVETo observe the expression of urotensin II (UII) on the lung of patients with pulmonary hypertension (PH) with congenital heart disease and investigate the meaning of this phenomenon.

METHODThirty eight patients with CHD were divided into three groups according to pulmonary arterial systolic pressure (PASP) measured in cardiac catheterization and surgery: normal pulmonary pressure group (N group, PASP < 30 mm Hg, n = 10), mild PH group (M group, PASP ≥ 30 mm Hg, n = 15), severe or moderate PH group (S group, PASP ≥ 50 mm Hg, n = 13). The expression of UII protein and UII mRNA in pulmonary arterioles were measured separately by immunohistochemical (IHC) analysis and in situ hybridization (ISH) analysis.

RESULT(1) The results of UIIIHC staining: The UII protein expression of group M was higher than that of group N (20.22 ± 3.58 vs. 14.34 ± 2.18, P < 0.01), but less than group S (20.22 ± 3.58 vs. 28.92 ± 3.22, P < 0.05). (2) The results of UIIISH mRNA staining were similar to IHC staining, the A value of group M was higher than group N (12.51 ± 2.02 vs. 8.85 ± 1.41, P < 0.05), less than that of group S(12.51 ± 2.02 vs. 25.35 ± 4.33, P < 0.01). (3) Correlation study: there was a positive correlation between the A values of UIIIHC and pulmonary hypertension (r = 0.64, P < 0.01, n = 38), a positive correlation between the A values of UIIISH and pulmonary hypertension (r = 0.58, P < 0.01, n = 38).

CONCLUSIONThere was the expression of Urotensin II protein and mRNA in the lung of pulmonary hypertension patients with congenital heart disease, and these expression may involve the formation of pulmonary hypertension of congenital heart disease.

OBJECTIVETo evaluate the expression of epidermal growth factor receptor (EGFR) gene copy number and the expression of ERCC1 and BRCA1 proteins in patients with non-small-cell lung cancer (NSCLC) and the correlation between them.

METHODSThe status of EGFR gene copy number was determined by in situ hybridization (FISH), and the expression of ERCC1 and BRCC1 proteins was examined by immunohistochemistry (IHC). The relationship of EGFR gene copy number with the expression of ERCC1 and BRCA1 and the clinical pathologic features were analyzed.

RESULTSFISH-positive EGFR expression was identified in 40 of 166 samples (24.1%). More FISH-positive EGFR in the female than male patients (31.9% vs. 18.6%, P = 0.048), and non-smoker than smoker (32.8% vs. 16.7%, P = 0.045). FISH-positive EGFR was not associated with age, pathological type, clinical stage and metestasis status (P > 0.05). The expression of ERCC1 protein was identified in 60 of 132 samples (45.5%). The expression of ERCC1 protein varied significantly in tumors of different pathological types (P = 0.046), but not associated with age, gender, clinical stage, metestatic status and smoking status (P > 0.05). The expression of BRCA1 protein was identified in 46 of 131 samples (35.1%). The expression of BRCA1 was not associated with age gender, pathological type, clinical stage, metestatic ststus and smoking status (P > 0.05). There was a moderate correlation between the expressions of ERCC1 and BRCA1 (r = 0.449, P < 0.001), but EGFR gene copy number was not correlated with the expression of ERCC1 or BRCA1 protein.

CONCLUSIONSFISH-positive EGFR expression is associated with gender and smoking status, but not correlated with the expression of ERCC1 and BRCA1 proteins. There is a moderate correlation between the expressions of ERCC1 and BRCA1.

Objective To explore the expression of HR and Her?2 in breast cancer primary tumor and axillary lymph node metastasis. Methods Four hundred and twenty?eight female patients with unilateral breast cancer combined with axillary lymph node metastasis treated in the Affiliated Suqian Hospital of Xuzhou Medical University from January 2011 to January 2016 were selected in this study. Immunohistochemistry was used to detect the expression of ER,PR,Her?2 and Ki67 in primary tumor and axillary lymph node metastasis. Results The positive rates of ER expression were 75. 9% ( 325/428 ) and 70. 3% ( 301/428 ) respectively in primary tumor and axillary lymph node metastasis. The positive rates of PR expression were 61. 4% ( 263/428) and 56. 1% ( 240/428 ) respectively in primary tumor and axillary lymph node metastasis. The rates of Her?2 overexpression were 20. 1% ( 86/428) in primary tumor and the positive rate of Her?2 in axillary lymph node metastasis was 22. 7%( 97/428 ) . The positive rates of Ki67 expression were 45. 6%( 195/428 ) and 39. 7%(170/428) respectively in primary tumor and axillary lymph node metastasis. The expression of ER,PR,Her?2 and Ki67 in primary and axillary lymph node metastasis showed no statistical significance ( P>0. 05 ) . The molecular typing of primary tumor and axillary lymph node metastasis were not consistent in 31 patients ( 31/428,7. 24%) ,including 14 cases of primary tumor Luminal A,9 cases of Her?2 overexpression in axillary lymph node metastasis and 5 cases of triple negative breast cancer. Primary tumor Luminal B was detected in 10 cases, while 6 cases of Her?2 overexpression in axillary lymph node metastasis and 4 cases of triple negative breast cancer. Primary tumor Her?2 was overexpressed in 4 cases,while 1 case of Luminal A,3 cases of Luminal B in axillary lymph node metastasis. There were 3 cases of primary tumor triple negative breast cancer,while 2 cases of Luminal B in axillary lymph node metastasis and 1 case of Her?2 overexpression. Conclusion The expressions of ER, PR, Her?2 and Ki67 in primary tumor and axillary lymph node metastasis of some breast cancer were different. Immunohistochemistry for primary tumor and axillary lymph node metastasis of stage II?III breast cancer patients should be routinely carried out. Based on molecular typing of primary tumor and axillary lymph node metastasis,individualized treatment plan can be developed,so that patients will benefit from it.

OBJECTIVEPrevious studies have shown that hydrogen sulfide (H2S) plays key roles in a number of biological processes, including vasorelaxation, inflammation, apoptosis, ischemia/reperfusion and oxidative stress, which are involved in the pathogenesis of myocarditis. This study aimed to examine the expression of cystathionine-γ-lyase(CSE)/H2S pathway in mice with viral myocarditis.

METHODSSix-week-old inbred male mice were randomly assigned to control (n=25) and myocarditis group (n=30). The myocarditis and the control groups were inoculated intraperitoneally with 0.1 mL 10-5.69TCID50/mL CVB3 or vehicle (PBS) alone respectively. Ten mice were sacrificed 4 and 10 days after injection. Blood and heart specimens were harvested for measuring the content of serum H2S and the H2S production rates in cardiac tissues. Heart sections were stained with hematoxylin and eosin. Immunohistochemisty was used to detect the CSE protein expression in the heart.

RESULTSIn the myocarditis group, the serum H2S content and H2S production rates in cardiac tissues were significantly higher than those in the control group 4 and 10 days after injection (P<0.05). The expression of CSE protein in the heart in the myocarditis group was also significantly higher than that in the control group (P<0.05).

CONCLUSIONSCSE and its downstream production H2S increase in mice with acute viral myocarditis. The increased expression of CSE/H2S pathway might be involved in the pathogenesis of viral myocarditis.
