Objective To observe the clinical efficacy of comprehensive muscle-region therapy based on Chuang Medicine in treating cervical spondylosis of neck type.Method A hundred patients with cervical spondylosis of neck type were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by the comprehensive muscle-region therapy based on Chuang medicine (muscle-region tuina, fire-needle acupuncture of Chuang medicine, and cupping), while the control group was by regular acupuncture treatment. The Visual Analogue Scale (VAS) score and symptoms and signs scores were observed before and after intervention, and the clinical efficacies were compared.Result The VAS scores respectively after 1 and 2 treatment courses were significantly different from that before intervention in the treatment group (P<0.05,P<0.01). The VAS score after 2 treatment courses was significantly different from that before intervention in the control group (P<0.05). After 2 treatment courses, the VAS score in the treatment group was significantly different from that in the control group (P<0.05). After treatment, the symptoms and signs scores (pain intensity, pain-affected area, number of tender points, limited motion, and general score) were significantly different from that before intervention in the treatment group (P<0.01, P<0.05). In the control group, the pain intensity, limited motion and general score after treatment were significantly different from that before intervention (P<0.05,P<0.01). After treatment, the symptoms and signs scores in the treatment group were significantly different from that in the control group (P<0.05,P<0.01). The total effective rate was 100.0% in the treatment group versus 84.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Comprehensive muscle- region therapy in Chuang medicine is an effective approach in treating cervical spondylosis of neck type.

OBJECTIVE：To optimize the water extraction and ethanol precipitation technology of Zhuang medicine Baijin granules. METHODS ：HPLC method was adopted to determine the content of bergenin in Baijin granules extract. The extraction routes of Baijin granules （water decoction ，70％ ethanol reflux extraction ，water decoction combined with 70％ ethanol reflux extraction）was screened primarily with the yield of extract and the experiment of reducing uric acid of mice. The orthogonal test was adopted to optimize water extraction technology of Baijin granules with water multiple ，extraction time and extraction times as factors，taking the extraction yield and the bergenin content as index ，then the validation test was carried out. The orthogonal test was adopted to optimize the alcohol precipitation process of Baijin granules including the relative density of medicinal materials ， alcohol content and the alcohol precipitation time ，then the validation test was carried out. By the experiment of reducing uric acid ， the effects of medicinal materials extract of Baijin granules extract were compared before and after ethanol precipitation. RESLUTS：Established method for content determination of bergenin with linearity range of 0.007 2-0.288 mg/mL，had good precision，reproducibility，stability and accuracy. The initially chosen extraction process of Baijin granules was water decoction extraction. The optimal water extraction technology was soaked for 0.5 h，then decocted for 3 times with 14-fold water （mL/g）and 1.0 h each time. The optimal ethanol precipitation process was to concentrate the water extract to a relative density of 1.0 g/mL with alcohol content of liquid at 60％ and precipitated for 12 h. Validation tests showed that RSDs of extract yield and beragenin content were all lower than 2％（n＝3）. The experiment of pharmacodynamics showed that water extract （before ethanol precipitation ）and water extract after alcohol precipitation could significantly decrease the level of uric acid in hyperuricemia model mice （P＜0.01）. There was no statistical significance in the reduction of uric acid between 2 groups（P＞0.05）. CONCLUSIONS ：The optimized water extraction technology can obtain good extract yield and bergenin content ，and combined with ethanol precipitation technology for removing excess impurities would not affect the pharmacodynamics. The water extraction and ethanol precipitation technology is feasible，and can be used for extracting the medicinal materials of Baijin granules and its edulcoration.

ObjectiveTo investigate effect of lyophilized powder of modified Huangqi Gancaotang on proliferation， apoptosis， invasion， migration， and epithelial-mesenchymal transition of human non-small cell lung cancer cells （A549， PC9） and possible mechanism. MethodEffect of 1.0， 2.0， 4.0， 8.0， 12.0 g·L^-1 modified Huangqi Gancaotang on the proliferation of non-small cell lung cancer cells was detected by cell counting kit-8 （CCK-8） assay. A549 and PC9 cells were classified into the blank group and the low-， medium-， and high-dose Huangqi Gancaotang groups （2.0， 4.0， 8.0 g·L^-1）. Plate cloning assay was used to examine the effect of modified Huangqi Gancaotang on cell cloning ability. Hoechst 33342 staining and flow cytometry were employed to detect the apoptosis， and scratch assay and Transwell migration assay were applied to examine cell migration and invasion abilities， respectively. Mammosphere assay was used to examine the sphere-forming ability of tumor cells， and real-time polymerase chain reaction （Real-time PCR） to detect the mRNA expression of stemness-related molecules octamer-binding transcription factor 4 （Oct-4）， human sex-determining region Y-box 2 （Sox2）， and homeobox transcription factor （Nanog） to assess cancer stem cell activity. The protein expression of B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated death promoter （Bad）， Bcl-2-associated X protein （Bax）， cleaved Caspase-3， Caspase-3， E-cadherin， N-cadherin， vimentin， matrix metalloproteinase-2 （MMP-2）， β-catenin， c-Myc， Cyclin D₁， and zinc-finger transcription factor （Slug） was determined by Western blot. ResultThe proliferation ability of A549 and PC9 cells was significantly inhibited after 24 h and 48 h treatment with 1.0， 2.0， 4.0， 8.0， and 12.0 g·L^-1 lyophilized powder of modified Huangqi Gancaotang compared with that in the blank group and the inhibition was dose- and time-dependent （P<0.05， P<0.01）. Compared with the blank group， the low-， medium-， and high-dose modified Huangqi Gancaotang suppressed the cloning ability of A549 and PC9 cells （P< 0.05， P<0.01）， and high-dose modified Huangqi Gancaotang induced apoptosis of A549 and PC9 cells （P<0.01）. In comparison with the blank group， the low-， medium-， and high-dose modified Huangqi Gancaotang inhibited the invasion and migration of A549 and PC9 cells （P<0.05， P<0.01）. Compared with the blank group， the low-， medium-， and high-dose modified Huangqi Gancaotang significantly decreased volume of the microspheres of A549 cells and the mRNA expression of Oct-4， Sox2， and Nanog in A549 and PC9 cells （P<0.05， P<0.01）. Compared with the blank group， the medium- and high-dose modified Huangqi Gancaotang down-regulated the expression of the anti-apoptotic protein Bcl-2 （P<0.05， P<0.01）， up-regulated the expression of pro-apoptotic proteins Bad， Bax， and cleaved Caspase-3/Caspase-3 （P<0.05， P<0.01） in A549 and PC9 cells， decreased the expression of MMP-2， N-cadherin， and vimentin （P<0.05， P< 0.01）， and raised the E-cadherin expression （P<0.05， P<0.01）. Moreover， the medium-dose and high-dose modified Huangqi Gancaotang all reduced the expression of β-catenin， c-Myc， Cyclin D₁， and Slug in A549 and PC9 cells （P<0.01）. ConclusionModified Huangqi Gancaotang can inhibit the proliferation， invasion， migration， activity of cancer stem cells， and epithelial-mesenchymal transition of human non-small cell lung cancer （A549， PC9） cells and induce apoptosis， and the mechanism is the likelihood that it regulates Wnt/β-catenin signaling pathway.

OBJECTIVE: To review the development of adult and pediatric liver transplantation in Tianjin First Center Hospital, and to enhance academic exchanges, improve technological innovation, and jointly promote the progress and maturity in the field of liver transplantation. METHODS: The development of liver transplantation in Tianjin First Center Hospital was analyzed. The clinical data of adult and pediatric liver transplantation from September 1998 to September 2018 were collected. The important events and technological innovation achievements of liver transplantation during the 20 years were summarized. RESULTS: The first clinical liver transplantation was attempted in Tianjin First Central Hospital in April 1980. The first long-term survival adult liver transplantation in China was completed in 1994 (11 years survival after the operation). The specialized team of liver transplantation was formally established in September 1998. The 20-year clinical exploration and progress reflected the characteristics of era changes and technological innovation during the rapid development of liver transplantation in China. Our center performed liver re-transplantation in January 1999, reduced-size pediatric liver transplantation in August 2000. In May 2001, we organized the formulation for the preventive and treatment plan for hepatitis B recurrence after liver transplantation. We performed combined liver and kidney transplantation in July 2002, split liver transplantation (SLT) in April 2004, the first domino liver transplantation (DLT) in August 2005. Pediatric living donor liver transplantation (LDLT) was initiated in October 2006, adult LDLT was carried out in August 2007. In September 2007, the first living donor combined liver and kidney transplantation from the same donor in Asia was performed. The first domino+living donor double grafts liver transplantation in the world was performed in January 2009. In March 2011, we performed laparoscopically assisted right hepatic lobe liver transplantation (LDLT) with middle hepatic vein. In May 2014, living donor laparoscopic left lateral lobe procurement was successfully established. In April 2016, simultaneous liver, pancreas and kidney multi-organ transplantation was completed. Domino donor-auxiliary liver transplantation was performed in February 2017. In December 2017, extracorporeal membrane oxygenation (ECMO)-supported liver transplantation in a patient with severe pulmonary hypertension was successfully completed. Liver transplantation combined with partial splenectomy was established in April 2018. Cross-domino liver transplantation (hypersensitive kidney transplantation with auxiliary liver transplantation+pediatric liver transplantation) was performed in May 2018. During the 20 years, the team has performed or assisted other centers in Beijing, Shanghai, Guangzhou and Shenzhen to carry out more than 10 000 cases of liver transplantations. A total of 7 043 cases of various types of liver transplantation were performed in the single center of the hospital (6 005 adult liver transplantations and 1 038 pediatric liver transplantations). Concerning adult liver transplantation, the cumulative 1-year, 3-year and 5-year survival rate from September 1998 to March 2003 were 83.1%, 73.0% and 69.0%, from April 2003 to March 2009 were 85.3%, 76.2% and 72.1% and from April 2009 to September 2018 were 87.5%, 79.2% and 75.1%, respectively. The cumulative 1-year, 3-year and 5-year survival rate for pediatric liver transplantation were 93.5%, 92.2% and 90.2%, respectively. The nucleoside (acid) analogue combined with low dose hepatitis B immunoglobulin (HBIG) was developed to prevent the recurrence of hepatitis B after liver transplantation, this plan has reduced the recurrence rate of hepatitis B and the 5-year re-infection rate of hepatitis B virus (HBV) after liver transplantation significantly. The risk assessment system for tumor recurrence after liver transplantation was established and individual treatment method was established based on this assessment system. Continuous exploration and improvement of liver transplantation for liver cancer, liver re-transplantation, liver transplantation with portal vein thrombosis, SLT, DLT and multi-organ combined transplantation have significantly improved the clinical efficacy of patients and the post-operative survival rate. CONCLUSIONS The liver transplantation team of Tianjin First Center Hospital has carried out a scientific and technological exploration on the key problems and technical difficulties of clinical liver transplantation. This work strongly has initiated and promoted the rapid development of liver transplantation in China. The restrictive barrier of hepatitis B recurrence after liver transplantation has been overcome. The risk prevention and control system of tumor recurrence after liver transplantation has been established. A series of innovative achievements that can be popularized have been achieved in the field of complex liver transplantation and expansion of donor liver source. The iterative progress and sustainable development of liver transplantation have been realized.
