ABSTRACT
This study aimed to evaluate the efficacy and safety of Chaihuang Granules in the treatment of upper respiratory tract infection in children. The databases such as CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, Web of Science, Chinese Clinical Trial Registry, and ClinicalTrials.gov were searched for randomized controlled trial(RCT) of Chaihuang Granules for the treatment of upper respiratory tract infection in children, and supplemented by manual searching of gray literature. Two investigators independently screened the literature, extracted data, and assessed the methodological quality. Meta-analysis was performed using RevMan 5.4 software, trial sequential analysis was conducted using TSA 0.9.5.10 Beta software, and evidence quality evaluation was carried out using GRADE profiler 3.6.1 software. Eighteen RCTs involving 2 459 patients(1 262 in the treatment group and 1 197 in the control group) were included. Meta-analysis showed that compared with conventional therapy alone, Chaihuang Granules significantly improved the total effective rate(RR=1.18, 95%CI[1.15, 1.22], P<0.000 01), reduced the disappearance time of symptoms/signs(MD=-1.39, 95%CI[-1.66,-1.12], P<0.000 01), improved cytokine levels(MD=-2.40, 95%CI[-3.80,-1.00], P=0.000 8), improved humoral immune levels(MD=0.75, 95%CI[0.60, 0.90], P<0.000 01), and reduced the recurrence rate(MD=-2.11, 95%CI[-2.98,-1.25], P<0.000 01). However, the incidence of adverse reactions was not increased(RR=0.94, 95%CI[0.59, 1.49], P=0.78). Subgroup analysis showed that:(1) both Chaihuang Granules used alone(RR=1.19, 95%CI[1.11, 1.27], P<0.000 01) and in combination with other therapies(RR=1.18, 95%CI[1.14, 1.22], P<0.000 01) effectively improved the total effective rate.(2) In terms of symptoms/signs disappearance time, Chaihuang Granules effectively reduced the duration of fever(MD=-1.18, 95%CI[-1.78,-0.58], P=0.000 1), cough with sputum(MD=-1.82, 95%CI[-2.38,-1.25], P<0.000 01), cough(MD=-1.31, 95%CI[-1.89,-0.74], P<0.000 01), sore throat(MD=-1.57, 95%CI[-2.25,-0.89], P<0.000 01), and lung rales(MD=-1.49, 95%CI[-2.06,-0.92], P<0.000 01).(3) Regarding cytokine levels, Chaihuang Gra-nules effectively improved the levels of interleukin(IL)-2(MD=-0.94, 95%CI[-1.16,-0.72], P<0.000 01), IL-6(MD=-4.71, 95%CI[-6.39,-3.03], P<0.000 01), and tumor necrosis factor-α(TNF-α)(MD=-2.07, 95%CI[-2.43,-1.71], P<0.000 01).(4) In terms of cellular immune levels, Chaihuang Granules effectively improved the levels of CD3~+(MD=4.11, 95%CI[1.53, 6.69], P=0.002), CD4~+(MD=4.21, 95%CI[1.69, 6.73], P=0.001), CD8~+(MD=-2.65, 95%CI[-3.93,-1.37], P<0.000 1), and CD4~+/CD8~+(MD=0.25, 95%CI[0.14, 0.37], P<0.000 1).(5) In terms of humoral immune levels, Chaihuang Granules effectively improved the levels of IgA(MD=0.44, 95%CI[0.23, 0.64], P<0.000 1), IgM(MD=0.31, 95%CI[0.15, 0.46], P=0.000 1), and IgG(MD=2.02, 95%CI[1.60, 2.43], P<0.000 01). Trial sequential analysis showed that the cumulative Z-curve of the total effective rate crossed the boundary value, further confirming its clinical efficacy. The GRADE evidence quality evaluation showed that the evidence quality of the above outcome indicators was low or very low, and the recommendation strength was weak. Compared to conventional therapy alone, Chaihuang Granules can effectively improve the total effective rate of treatment, alle-viate symptoms and signs of upper respiratory tract infection in children, improve inflammatory conditions, enhance immune function, and reduce the recurrence rate. Due to the limited quality of the included studies, high-quality RCT is still needed to provide evidence support for the above conclusions.

This study aims to evaluate the efficacy and safety of Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. Computer-based online searching of CNKI, VIP, SinoMed, Wanfang, ChiCTR, ClinicalTrials.gov, Cochrane Library, PubMed, EMbase, and Web of Science was performed to retrieve the randomized controlled trial(RCT) regarding Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. In addition, manual searching of gray literature was conducted. After two evaluators independently selected articles, extracted data, and evaluated the quality of methodology included in the studies, Meta-analysis was carried out in RevMan 5.4 and trial sequential analysis(TSA) in TSA 0.9.5.10 Beta. GRADE profiler 3.6.1 was employed to evaluate the evidence quality. A total of 21 RCTs were included in this study, involving 2 651 patients(1 330 patients in the observation group and 1 321 patients in the control group). Meta-analysis showed that compared with conventional western medicine alone, Compound Qinlan Oral liquid improved the total response rate(RR=1.15, 95%CI[1.12, 1.19], P<0.000 01) without increasing the incidence of adverse reactions(RR=0.77, 95%CI[0.47, 1.25], P=0.16). The results of subgroup analysis are described as follows:(1) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid improved the total response rate(RR=1.10, 95%CI[1.05, 1.14], P<0.000 01) and shortened the time to symptom relief(SMD=-0.76, 95%CI[-1.02,-0.51], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=1.16, 95%CI[0.54, 2.47], P=0.71).(2) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid + conventional western medicine improved the total response rate(RR=1.20, 95%CI[1.15, 1.25], P<0.000 01), decreased traditional Chinese medicine(TCM) syndrome scores(MD=-0.58, 95%CI[-0.75,-0.41], P<0.000 01), shortened the time to symptom relief(SMD=-2.44, 95%CI[-3.09,-1.80], P<0.000 01) and physical sign improvement(MD=-2.57, 95%CI[-4.11,-1.04], P=0.001), lowered the serum levels of inflammatory cytokines(SMD=-2.16, 95%CI[-2.61,-1.70], P<0.000 01), improved respiratory function indicators(SMD=1.48, 95%CI[1.00, 1.96], P<0.000 01), and enhanced the humoral immunity(MD=0.94, 95%CI[0.69, 1.18], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=0.57, 95%CI[0.29, 1.09], P=0.09). TSA showed that the cumulative Z curve of total response rate crossed the traditional threshold and TSA threshold, further confirming the clinical efficacy of Compound Qinlan Oral Liquid. The GRADE graded the evidence of the above outcome indicators as low or extremely low, and yielded weak recommendation. Compared with conventional western medicine alone, Compound Qinlan Oral Liquid can improve the total effective rate and reduce the time to symptom relief. The combination of Compound Qinlan Oral Liquid and conventional western medicine can improve the total response rate, mitigate the symptoms and improve the physical signs, reduce inflammation, and improve respiratory function and immunity of the patients with acute upper respiratory tract infection. In view of the limited number and quality of the included studies, the above conclusions still require high-quality RCT to provide evidence support.

The discovery of small-molecule drugs for the treatment of COVID-19 is one of the most concerned research fields in drug discovery. Different kinds of small-molecule drugs approved or being developed are currently under clinical studies for the treatment of COVID-19. At present, the design of most clinical trials for the treatment of COVID-19 is lack of rationality. Moreover, the efficacy of drugs is controversial. High-quality results of clinical research are urgently needed. There is no small-molecule drugs in clinical studies that have specific effects on SARS-CoV-2. To find more drug candidates, artificial intelligence, structure-based drug design and other methods are applied to discover pre-clinical small molecule compounds against important protein targets of SARS-CoV-2 and virus host. Resources should be further integrated to discover drugs with specific effects to treat COVID-19.

Seeds of Bupleurum chinense cultivar, Zhongchai No. 1, were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15, 20, 25, 15-25 degrees C) and light (8,12 h) to germinate, respectively. The lower constant temperature (15 degrees ) and the higher constant temperature (25 "C) were not conducive to the sprouting characteristics of B. chinese. While they were able to enhance root activity to some extent; The seeding growth of B. chinese was significantly better in the variable temperature than correspondence in the constant temperature, significantly. The emergence speed, emergence index, vigor index and root activity of Bupleurum were improved under the 12 h of light-time, but the germination rate was not improved. The sprouting of Bupleurum's seeds could be improved to some extent by soaking with hormone, such as gibberellin, cytokinin, salicylic acid. Gibberellin promoted seeds' sprouting and seedings's root activity of Bupleurum, while salicylic acid increased the root activity of seeding. There is a significant influence of light, temperatures and hormone treatment on the germination of Zhongchai No. 1 seeds, and all three are remarkably interacted; It is beneficial to promote seed germination by the temperature (20 + 5) degrees C, lighting (8 h) and gibberellin concentration (10 x 10(-6)).

<p><b>OBJECTIVE</b>To discuss the relevant factors of biliary complications after liver transplantation and to investigate the value of comprehensive management for the complications.</p><p><b>METHODS</b>The data of 366 patients undergoing liver transplantation from October 2000 to March 2012 was analyzed retrospectively, and the risk factors were analyzed by univariate analysis and Stepwise Logistic regression. The cases with biliary leak were administered thorough drainage. The cases with anastomotic biliary stricture were administered sacculus dilatation through percutaneous transhepatic cholangiography (PTC) and endoscopicretrograde cholangiopancreatography (ERCP). If necessary, some cases were placed biliary tract brackets. The patients with nonanastomotic biliary stricture were treated with PTC plus choledochoscope.</p><p><b>RESULTS</b>All the 366 patients were followed up for 58.5 (10 to 129) months. Biliary complications after liver transplantation were diagnosed in 42 cases among these patients. The incidence for biliary complications was 11.5%. The univariate analysis and multivariate Logistic regression analysis showed that the second warm ischemia period and the blood loss and the damage of blood supply and the diameter of biliary anastmosis were significantly associated with biliary complications after liver transplantations (Wald = 9.474 to 17.208, P < 0.05). Twelve cases with biliary leak were cured through abdominal and nasobiliary drainage. Twenty-two cases with anastomotic biliary stricture were administered sacculus dilatation through ERCP or PTC and were cured, including 6 cases were placed biliary tract brackets. Among 8 cases with nonanastomotic biliary stricture, 6 cases were cured through PTC associating with choledochoscope. One case was treated second liver transplantation and another case got worse.</p><p><b>CONCLUSIONS</b>Ischemic injury and the diameter of anastmosis are risk factors for biliary complications after liver transplantations. The interventional management of biliary stricture and bile leakage after liver transplantation is safe and effective.</p>

<p><b>OBJECTIVE</b>To study the clinicopathologic and immunohistochemical features, biological behavior, diagnosis and treatment of solid pseudopapillary tumor of the pancreas (SPTP).</p><p><b>METHODS</b>A retrospective clinical and clinicopathologic analysis was made on 33 cases of SPTP admitted from May 2001 to 2010 July. There were 7 male and 26 female patients, aging from 13 to 66 years with a mean of 34.3 years.</p><p><b>RESULTS</b>The tumor was located in pancreatic head of 10 patients, in pancreatic neck of 5 patients, in pancreatic body and tail of 18 patients. Of the 33 patients treated with surgery, 8 underwent simple resection of pancreatic tumor, 6 underwent pancreaticoduodenectomy, 3 underwent tumor resection plus pancreaticojejunostomy, 1 underwent tumor resection plus pancreaticogastrostomy, 11 underwent distal pancreatectomy, 4 underwent distal pancreatectomy plus spleen resection (1 underwent mesohepatectomy for hepatic metastasis). Sixteen of the 33 operations were completed by laparoscopy. Histologically, tumors were composed of papillary and microcystic solid structures, with uniformed population of cells. The pancreas and blood vessels invasion were identified in 3 cases, one of them was combined with liver metastasis, and they are male. Immunohistologically, the tumors were positive for α1-antitrypsin, α1-antichymotrypsin, β-catenin, CD10, CD56 and vimentin (all cases), neuron-specific enolase (3 cases), synaptophysin (6 cases), chromogranin A (4 cases), progesterone receptor (28 cases), estrogen receptor (3 cases), S-100 (6 cases). Totally 33 cases were followed up with a median period of 49 months without tumor recurrence.</p><p><b>CONCLUSIONS</b>SPTP is of low graded malignancy. It primarily affects young women. It may be located in any part of pancreas. Immunohistochemistry is very important for the diagnosis and differential diagnosis of SPTP. Surgical resection is recommended as the treatment of choice. Laparoscopic distal pancreatectomy or tumor resection is feasible and safe for some selected patients, and the prognosis is good.</p>

<p><b>OBJECTIVE</b>To analyze the risk factors for acute renal failure (ARF) early after liver transplantation.</p><p><b>METHODS</b>The data of 362 patients undergoing liver transplantation from August 2000 to December 2010 were retrospectively analyzed, including 71 patients with ARF (ARF group) and 291 without ARF (non-ARF group). Thirty-six variables, including clinical and experimental variables, were analyzed by t test for continuous variables and χ(2) test for discrete variables. The variables with significance (P < 0.05) were then analyzed with Stepwise logistic regression.</p><p><b>RESULTS</b>Twelve variables, including pretransplant serum creatinine, hemoglobin, thrombinogen activity, total bilirubin, MELD scores, total operation time, intraoperative blood loss, intraoperative blood transfusion, preoperative urine output, preoperative hepatic encephalopathy, intraoperative low blood pressure and postoperative infection, had significant difference between two groups (F = 10.30 - 182.70, P = 0.000 - 0.041). The Stepwise logistic regression analysis for 12 variables demonstrated that the high level of pretransplant serum creatinine, the low pretransplant thrombinogen activity, the high MELD scores, the large volume of intraoperative blood loss, postoperative infection were the independent risk factors of ARF complicated to orthotopic liver transplantation (P < 0.05).</p><p><b>CONCLUSIONS</b>Early ARF is a key negative factor for the survivors after orthotopic liver transplantation. The reason for ARF complicated to OLT is multiple. The high level of pretransplant serum creatinine, the low pretransplant thrombinogen activity, the high MELD scores, the large volume of intraoperative blood loss, postoperative infection were the independent risk factors of ARF complicated to orthotopic liver transplantation.</p>

<p><b>BACKGROUND</b>The coagulation function in patients with pancreatic carcinoma is abnormal and the reason is not very clear. In this study, we retrospectively analyzed the coagulation function in patients with pancreatic carcinoma.</p><p><b>METHODS</b>From June 2004 to December 2007, 132 patients received diagnosis and treatment in our hospital. The coagulative parameters including the prothrombin time, activated partial thromboplastin time, and fibrinogen levels were collected and studied retrospectively.</p><p><b>RESULTS</b>The average fibrinogen levels in patients with pancreatic carcinoma, (476.21 +/- 142.05) mg/dl, were significantly higher than in patients with cholangiolithiasis, (403.28 +/- 126.41) mg/dl (P < 0.05). In patients with pancreatic carcinoma, the levels of fibrinogen in the group with jaundice were significantly higher than in patients without jaundice (P < 0.05). In patients who received Pancreaticoduodenectomy, Whipple's operation, the level of fibrinogen in the group with local invasiveness was significantly higher than in the group without invasiveness. The group with lymphatic metastasis had higher levels than the group without lymphatic metastasis (P < 0.05). There was no significant difference of intraoperative blood loss between patients with vitamin K, (748.27 +/- 448.51) ml, and those without vitamin K, (767.31 +/- 547.89) ml (P > 0.05).</p><p><b>CONCLUSIONS</b>The level of fibrinogen in patients with pancreatic carcinoma was elevated. The elevated fibrinogen level may be associated with invasiveness and lymphatic metastasis. Using vitamin K in perioperation management did not reduce intraoperative blood loss.</p>
