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 effects of Rubiae Radix et Rhizoma (RRR) and carbonized Rubiae Radix et Rhizoma (CRRR) on the acute blood stasis rat model, and reveal their differences in efficacy.

METHODThe acute blood stasis model was induced by subcutaneously injecting adrenaline hydrochloride and soaking in ice water. Yunnan Baiyao was used as the positive control drug, and administered for consecutively seven days. This model was adopted to observe the effect of high, middle and low dose RRR and CRRR groups on hemorheology, thrombin activity, and blood platelet system.

RESULTRRR could significantly reduce the wholeblood viscosity and plasma viscosity of blood stasis rats under different shear rates, and showed certain two-way regulating function in hemostasis. It also showed certain effect on ADP-induced platelet aggregation rate, but which was lower than CRRR. CRRR achieved the main hemostatic mechanism by stimulating intrinsic and extrinsic blood coagulation and fibrinogen, and could significantly enhance the platelet aggregation rate of rats in the acute blood stasis model (P <0. 01).

CONCLUSIONRRR had the effect of removing blood stasis and hemostasis, while CRRR mainly has the hemostatic effect. This further demonstrates the traditional processing theory of "promoting blood circulation with crude herbs and stopping bleeding with processed herbs".

Fatty acids of Ralstonia solanacearum cultured under different temperatures, times, pH values and cultural media were detected by using gas chromatography (GC) method. Rs-J.1.4-010704-01v, a viru- lent strain of R. solanacearum isolated from ginger was chosen for the experiment. The results showed that the kind of fatty acid of Rs-J.1.4-010704-01v fluctuated from 14 to 33. The contents of its three plentiful fatty acids, C16:1?7c/C15:0 ISO 2OH, C16:0 and C18:1?7c (with retain times of 10.644, 10.950 and 14.177 min, respectively), also varied in a range of 55.66% to 75.69%. The diversification of the bacterium’s fatty acids at various cultural conditions was clustered into four groups by cluster analysis, according to the kinds and percentage contents of the fatty acids detected. The pathogenicities of Rs-J.1.4-010704-01v under 20?C and 25?C were deduced to be mid-virulent, with C16:0 less than C16:1?7c/C15:0 ISO 2OH. The bac- terium showed as a virulent strain under the other cultural conditions including 30?C~40?C, 24 h~96 h, pH 5~9 and four cultural media (LB、NA、TTC and TSB), with C16:0 more than C16:1?7c/C15:0 ISO 2OH.However, the difference between C16:0 and C16:1?7c/C15:0 ISO 2OH raised significantly from 2.35 to 13.23 under 40?C and 48 h~96 h. Meanwhile, the kind of fatty acid increased more than 30 as the cultural time increased. It was concluded that temperature and cultural time had more significant effects on the fatty acid composition of R. solanacearum than pH value and cultural medium.

Abstract: Objective　To analyze the emergency response and long-term intervention effects after the detection of infectious snails epidemic by loop-mediated isothermal amplification (LAMP) assays in Hannan District, Wuhan City, and to explore the application of LAMP in early surveillance and early-warning of schistosomiasis transmission. Methods Snails picked up by the risk monitoring system in Hannan District were examined by anatomical microscopy and LAMP technology to identify the schistosomiasis infection. Emergency response and intensive intervention were initiated in the environment where positive snails appeared, and the long-term effects were evaluated. Results In May 2018, the infectious snails were detected by LAMP technology in Hannan District, and the positive snails were located in Zhujiacha, Dongzhuang Village, Obstacles and weeds were removed and buried by machine in Zhujiacha. 12 700 m2 of snails were killed by drugs, and the mortality rate of snails was more than 80%; no new seropositive persons were found in the emergency examination within 500 m of the positive snail sites. 506 people were examined in Dong Zhuang Village at the end of the year, and 30 positive IHA cases were detected with a blood positive rate of 5.93%, no positive fecal test was found, and all positive blood test patients took preventive medication. The monitoring results of sentinel rats and wild feces were all negative. Health education was carried out, 7 warning signs were deployed and refreshed, and 500 publicity brochures were distributed. After nearly three years of intensified intervention and monitoring in the villages where the positive environment is located, and the density of snails on the stubborn snail has dropped from 0.094/frame to 0.027/frame, and the positive rate of blood test in Dongzhuang Village has steadily dropped from 5.93% to 3.74%. Conclusions The infected snails missed by microscopy were detected by LAMP in Hannan District, which created conditions for the rapid emergency treatment of environment and elimination of positive snail and improved the sensitivity of the surveillance and early warning system in transmission-interrupted areas.

OBJECTIVETo investigate the effects of the tension skin flap with different shapes on the transplantation of the reverse neurocutaneous island flap.

METHODSFrom January 2006 to January 2012,there were 21 patients in the study (including 15 males and 6 females), and aged from 14 to 58 years old (35 years old on average). Tension skin flaps with different shapes (triangle ,round and ellipse) were used to improve the blood supply of the reverse neurocutaneous island flap. The tension skin flaps in the pedicle were designed triangularly (10 patients), spherically (8 patients) or elliptically (3 patients). There were 5 patients with defects in the hand (the size from 5.0 cm x 2.0 cm to 8.0 cm x 5.0 cm), and 16 patients with defects in the foot and inferior segment of leg, or around the ankle (the size from 6.0 cm x 4.0 cm to 13.0 cm x 7.0 cm). And all the patients were with the tendon and bone exposed. All the flaps were reversal transplanted, including 5 dorsal neurocutaneous flaps of foot, 4 superficial peroneal neurocutaneous flaps, 4 saphenous neurocutaneous flaps, 3 sural neurocutaneous flaps, 2 superficial radial neurocutaneous flaps, 3 lateral neurocutaneous flaps of forearm. And the survival rate, appearance and sensory recovery of the flaps were analyzed.

RESULTSThe distant part of the reversed sural neurocutaneous island flap in 1 case necrosized and healed after dressing change. The other flaps survived entirely, and the donor site all healed primarily. The follow-up time was from 3 months to 2 years (averaged 7 months), and all the flaps had recovered pain and warm sensation with perfect appearance.

CONCLUSIONThe tension skin flap in the pedicle can enhance the blood supply and promote survival rate of the reverse neurocutaneous island flap, and can also improve its appearance.

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.

OBJECTIVETaking Chinese compound medicine Yuchangning as a research model, prepared the pH and time dependent Yuchangning tablets for colon-specific delivery (PT-YT-CSD), and evaluated the releasing property in vitro.

METHODThe coating prescription is filtered by the release extent of matrine and oxymatrine in vitro and the wicking rate of the tablet, which including the category and proportion of film forming agent and porogen, the sort and dosage of fluidizing agent, the increment of weight after coating and so on. The releasing property of the preparation is evaluated by the dissolution tests in vitro through measuring the content of matrine and oxymatrine content.

RESULTThe preparation method of the PYTCSD: After prepared plain tablets, the 95% alcoholic solution of EC and Eudragit II are mixed in a 7:3 EC: Eudragit II ratio and then added in DEP up to 10% of the coating amount, reduced the alcohol concentration to 4% by diluting with ethonal. Tablet was coated by the alcohol solution and the weight of the plain tablet was increased by 3%. The dissolution tests in vitro indicated that matrine and oxymatrine were not dissolved in the simulated gastric juice after 2 h. The accumulative quantities of matrine and oxymatrine were less than 10% in the simulated intestinal juice after 4 h. The quantities of matrine and oxymatrine are 75.7% and 76.8% in the simulated colon juice after 1 h.

CONCLUSIONThe PYTCSD was prepared and the preparation could fulfil the aim of delivering in the specific colon in vitro.

BACKGROUND AND OBJECTIVEThe platinum-based chemotherapy combined with 5-fluorouracil (5-FU) is most frequently used for nasopharyngeal carcinoma (NPC), but the efficacy has been maintained at 50%-60%. Docetaxel is an effective drug for head and neck tumors, its administration is simple, and the administration time is short. This study was to compare the short-term efficacy and toxicity between TC regimen (inductive chemotherapy with docetaxol plus carboplatin) and FC regimen (5-FU plus carboplatin) in local advanced NPC so as to provide a new chemotherapeutic regimen for NPC.

METHODSFifty-eight local advanced NPC patients without previous treatment in Sun Yat-sen University Cancer Center were randomly assigned to receive either TC or FC regimen inductive chemotherapy, followed by concurrent chemoradiotherapy with two cycles of carboplatin (AUC=6) plus radiotherapy of 60-78 Gy to the nasopharynx and 60-70 Gy to the neck. The short-term efficacy and adverse events were observed.

RESULTSMore chemotherapy cycles were finished in TC group than in FC group (3.31 vs. 2.83, P = 0.043). There was no significant difference in short-term efficacy and 1-year survival rate between the two groups (P > 0.05). More grades 3-4 neutropenia appeared in TC group than in FC group (72.4% vs. 37.9%, P < 0.05) , whereas less thrombocytopenia and emesis occurred in TC than in FC group (P = 0.013 and 0.018, respectively).

CONCLUSIONSThe short-term efficacy of TC regimen in local advanced NPC is similar to that of FC regimen with tolerable adverse events. But the long-term outcomes and toxicities need to be further investigated.
