Objective To investigate the protective effects of G CSF on lungs of rats with acute cholangitis and changes in blood TNF and TXA 2/PGI 2 by treating the rats with G CSF. Methods Seventy two Wistar rats were randomized into the control, infected and treated groups. We established the model of cholangitis in the rats with injection of E. coli 25922 into the bile duct. The animals in the treated group were pretreated with G CSF 500 ng/day bid) for 5 days before the E. coli injection. The levels of blood TNF and TXA 2/PGI 2 were measured at the 3rd, 6th and 12th h after the injection. Meanwhile, the morphological changes in lungs of the rats were observed. Results The morphological changes in lungs were milder and levels of blood TNF and TXA 2/PGI 2 were significantly lower in the treated group than in the infected one (P

Objective:Clinicopathological features, treatment and prognosis of urinary and male reproductive system soft tissue sarcoma (STS) and sarcomatoid carcinoma in adults were compared.Methods:A retrospective analysis was performed on the clinical data of 73 patients with STS and 15 patients with sarcomatoid carcinoma in adult urinary and male reproductive system in the First Affiliated Hospital of Zhengzhou University. There were 59 males and 14 females in STS group, with a median age of 41 (18-78)years old. The maximum tumor diameter ranged from 0.5 to 19.0 cm. The primary tumors were located in testis and peritesticular (23 cases), kidney (23 cases), prostate (15 cases), bladder (8 cases), ureter(3 cases), other parts(1 case). There were 18 cases of lymph node metastasis and 8 cases of distant metastasis. Among 73 patients with STS, 66 patients underwent surgical resection, of which 31 patients underwent radical resection. Among the 66 patients who underwent surgery, 3 patients received neoadjuvant chemotherapy; 22 patients received adjuvant chemotherapy; 5 patients were treated with adjuvant radiotherapy. Among 7 patients with STS did not receive surgical treatment, 2 patients received radiotherapy combined with chemotherapy, 2 patients received chemotherapy alone, and 3 patients received symptomatic support treatment.There were 11 males and 4 females in sarcomatoid carcinoma group, with a median age of 65 (23 - 84)years old. The measurable tumor diameter ranged from 0.4 to 16.9 cm. The primary tumors were located in kidney (6 cases), bladder (5 cases), ureter(2 cases) and prostate(2 cases). There were 2 patients of lymph node metastasis and 4 patients of distant metastasis. Of the 15 patients with sarcomatoid carcinoma, 12 patients underwent surgical resection, of which 5 patients underwent radical resection. 2 patients were treated with adjuvant therapy after operation. Among the 12 patients who received surgical treatment, 2 patients had distant metastasis before operation, all of which originated from the kidney. Among the 3 patients without surgical treatment, 1 patients received systemic chemotherapy and 2 patients received symptomatic supportive treatment. There was no significant difference in gender, tumor maximum diameter, distant metastasis and operation, chemotherapy, radiotherapy and operation combined with chemotherapy ( P>0.05) and there were significant differences in age, tumor primary location and lymph node metastasis ( P<0.05) between STS and sarcomatoid carcinoma patients.The categorical variables of the two groups were compared by χ2.With Kaplan-Meier method for univariate survival analysis, the Cox was used for multivariate analysis. Results:The median follow-up time was 18.3(0.3-90.4) months.In STS group, there were 14 patients of synovial sarcoma, 11 patients of liposarcoma, 15 patients of rhabdomyosarcoma, 16 patients of leiomyosarcoma, 10 patients of other types, and 7 patients of spindle cell sarcoma without specific classification. Among 66 patients with STS, 8 patients recurred, 14 patients metastasized after operation, 4 patients recurred and metastasized after operation. The 7 patients without surgical treatment all progressed. Among the 10 patients of sarcomatoid carcinoma without distant metastasis before operation, 3 patients recurred and 3 patients metastasized after operation. Two patients of renal sarcomatoid carcinoma with distant metastasis were treated with nephrectomy and chemotherapy. One of them had overall survival (OS) up to 2 years, and one recurred 2 months after operation. The 3 patients without surgical treatment all progressed without remission. The median OS of STS patients were 59.3 (95% CI 24.1-94.5) months and that of sarcomatoid carcinoma patients were 8.7 (95% CI 6.1-11.2) months. The OS of STS patients were better than those of sarcomatoid carcinoma patients ( HR=2.874, 95% CI 1.118-7.386, P=0.022). Conclusions:The onset age of STS in adult urinary and male reproductive system was lower than that in sarcomatoid carcinoma. The primary lesions of STS were mainly in testis, peritesticular and kidney. The primary lesions of sarcomatoid carcinoma were mainly in kidney. Among STS, leiomyosarcoma was the most common type.STS and sarcomatoid carcinoma should be diagnosed and treated with surgery quickly, and systemic therapy should be performed for patients who cannot be treated with surgery.

OBJECTIVETo investigate the cardiac effect of QT interval prolongation in the treatment of acute promyelocytic leukemia (APL) with arsenic trioxide (As(2)O(3)), and the relationship between QT and serum arsenic concentration.

METHODSBlood serum arsenic concentrations of thirty APL patients were determined at 2 hours, 4 hours, 8 hours, and 24 hours after As(2)O(3) injection using atomic fluorophotometry. Cardiac functions were measured simultaneously using a 12-lead body-surface electrocardiogram (ECG). Q-T intervals were manually measured, and then corrected using Bazett's formula (QTc). QT dispersion (QTd) was also calculated. In order to assess the effects of arsenic on the symptoms of anemia, twenty-four anemia patients were divided into two groups on the basis hemoglobin concentration: Group 1 (Hb > or = 90 g/L), and Group 2 (60 g/L < or = Hb < 90 g/L). QTc and QTd of these patients were also manually measured.

RESULTSAll QT intervals of APL patients treated with As(2)O(3) injection were prolonged [32.2 ms (27, 41 ms); P < 0.05], but the changes of QTd were not prominent [3 ms (-8, 7 ms), P > 0.05]. There was a delay of 2 hours in maximum QTc following peaks in serum arsenic concentration. Changes in QTc and QTd of the two anemic groups were not prominent.

CONCLUSIONSAs(2)O(3) can prolong QTc intervals in APL patients, but the effects are delayed compared to peak serum arsenic concentrations. As(2)O(3) has no prolongation effect on QTd. Mild and moderate anemia do not effect QTc and QTd.

OBJECTIVETo investigate the effects of early enteral nutrition supplemented with immune nutrient on intestine immune function in mice with severe burn.

METHODSTwenty-four BALB/c mice were inflicted with 20% TBSA full-thickness scald, then they were randomly divided into EN(with oral administration of common enteral nutrition after 2 hours) and EIN (with oral administration of common enteral nutrition and glutamine, arginine after 2 hours) groups. Another 10 mice were used as the normal control (NC) group. The supplied energy ratio( carbohydrate: fat: protein)in former 2 groups was 82:3:15, and the ratio of energy to nitrogen was 150: 1. The energy requirement of each mouse was calculated according to 732.2 kJ x kg(-1) x d(-1), one third of the requirement was administrated on 1st day, and one half of it on 2nd day, and full energy requirement was started on the 3rd day,and the requirement was divided into 4-6 portions every day. The feed was isocaloric, isonitrogenous, and isovolumic for the 2 experimental groups. All mice were sacrificed and entire small intestine was harvested for determination of intestinal IgA level by ELISA, total Peyer's patches (PP) lymphocytes and their apoptosis ratio, and changes in PP lymphocytes (CD3+, CD4+, CD19+) on 7th day of the experiment.

RESULTSCompared with those in NC group [(4.5 +/- 0.6) x 10(6), (42 +/- 7) microg/cm, respectively], total PP lymphocytes and intestinal IgA levels in EN and EIN groups obviously decreased [(2.3 +/- 0.4) x 10(6), (35 +/- 6) microg/cm, (3.8 +/- 0. 5) x 10(6), (38 +/- 6), microg/cm, respectively, P < 0.05] , among which the values in EIN group were higher than EN group (P < 0.05). The changes in PP lymphocytes were similar to that of total PP lymphocytes. Compared with that in NC group [(4.8 +/- 2.1)%], the apoptosis ratio of PP lymphocytes in EN and EIN groups significantly increased [(12.7 +/- 2.4)%, (8.0 +/- 1.7)%, respectively, P < 0.05], however the ratio in EIN group was lower than that of EN group (P < 0.05).

CONCLUSIONSEarly enteral nutrition supplemented with immune nutrient can improve intestinal immune function in mice with severe burn.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.

This article reports the clinical and genetic features of two cases of cerebral creatine deficiency syndrome I (CCDSI) caused by SLC6A8 gene mutations. Both children were boys. Boy 1 (aged 2 years and 10 months) and Boy 2 (aged 8 years and 11 months) had the clinical manifestations of delayed mental and motor development, and convulsion. Their older brothers had the same symptoms. The mother of the boy 1 had mild intellectual disability. The genetic analysis showed two novel homozygous mutations, c.200G>A(p.Gly67Asp) and c.626_627delCT(p.Pro209Argfs*87), in the SLC6A8 gene on the X chromosome, both of which came from their mothers. These two novel mutations were rated as possible pathogenic mutations and were not reported in the literature before. This study expands the mutation spectrum of the SLC6A8 gene and has great significance in the diagnosis of boys with delayed development, and epilepsy.

【Objective】 To study the impact of lupus flares on pregnancy outcomes in pregnant patients with systemic lupus erythematosus(SLE), and analyze the risk factors of adverse pregnancy outcomes. 【Methods】 Data were obtained from 95 pregnancies of 89 patients with SLE between January 1, 2013 and December 31, 2018 at The Third Affiliated Hospital of Sun Yat-sen University and its Lingnan Branch. The relationship between lupus flares and pregnancy outcomes, and the risk factors for adverse pregnancy outcomes were analyzed. 【Results】 ①The disease changes were evaluated by SLEDI and divided into two groups. Lupus flares occurred in 39 pregnancies(group A), and stable lupus disease was observed in 56 pregnancies(group B). The activity rate of lupus flares was 41.05%, compared with pregnancies in patients with stable lupus disease before pregnancy, pregnancies in patients with first onset pregnancy and unplanned pregnancy before pregnancy had higher lupus flares during pregnancy(100% vs. 28.21%, P < 0.05). ②Adverse pregnancy outcomes: the incidence of fetal loss, preterm labor, intrauterine growth retardation, preeclampsia and active lupus nephritis in group A was 20.51%, 35.90%, 43.59%, 17.95% and 41.02%, respectively, which was significantly higher than those of the group B(1.8%, 14.29%, 17.86%, 3.57% and 0, respectively) (P < 0.05). There was no difference in fetal distress, neonatal asphyxia and neonatal lupus between the two groups(10.26% vs. 1.79%, 7.69% vs. 1.79%, 2.56% vs. 0, respectively; P > 0.05). ③The Logistic regression analysis showed that unplanned pregnancy before pregnancy, active lupus nephritis during pregnancy, aPL positive and antiSSA positive were risk factors for adverse pregnancy outcomes(P < 0.05) . 【Conclusions】 Conception timing for pregnant women is crucial to lupus flares during pregnancy. Lupus flares during pregnancy increase the incidence of fetal loss, preterm labor, intrauterine growth retardation, preeclampsia and active lupus nephritis. Unplanned pregnancy before pregnancy, active lupus nephritis during pregnancy, aPL positive and antiSSA positive are associated with adverse pregnancy outcomes.

Ulcerative colitis (UC) is a chronic non-specific inflammatory bowel disease, listed as a modern refractory disease by the World Health Organization, which is difficult to recover, whereas it is easy to be attacked repeatedly. UC pathogenesis is closely related to gut microbiota dysbiosis. The gut microbiota interacts with bile acids (BAs), short-chain fatty acids (SCFAs), tryptophan, and other metabolism, immune system, intestinal barrier, etc., which regulate each other and affect the occurrence and development of UC. The active ingredients of traditional Chinese medicine (TCM), single herb and its extracts, and formulae can effectively alleviate UC symptoms by regulating the diversity, structure, composition, and metabolites of gut microbiota. In this review, the TCM based on the regulation of gut microbiota in the treatment of UC and its related mechanism for nearly three years was summarized.
