Objective To observe the effect of heat needle treatment on the inflammatory reaction in the damaged tissues of rats with the third lumbar transverse process syndrome. Methods Ninety Sprague-Dawley rats were randomly divided into 6 groups, namely normal group, model group, drug group, heat needle group, conventional acupuncture group and warming acup-moxibustion group, 15 rats in each group. The rat model of the third lumbar syndrome was established by embedding gelatin sponge. Two weeks later, the rats in various groups were given corresponding treatment respectively. Before treatment and on the 7th, 14th and 28th day of treatment, the blood samples were collected from jugular vein, and then the serum inflammatory cytokines of tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β and IL-6 were detected by enzyme-linked immunosorbent assay (ELISA). On the 28th day of treatment, all of the rats were sacrificed, the expression levels of TNF-α, IL-1βand IL-6 mRNA in the muscle tissue were detected by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR), and the pathological changes in local muscle tissue were observed by HE staining method. Results The serum contents of the inflammatory cytokines of TNF-α, IL-1β and IL-6 in the model group and treatment groups after modeling were significantly higher than those in the normal group (P < 0.05). After treatment, the contents of TNF-α, IL-1β and IL-6 in various treatment groups were decreased significantly as compared with those in the model group, and the decrease was most obvious in the heat needle group. The expression levels of TNF-α, IL-1β and IL-6 mRNA in muscle tissues of drug group, heat needle group, conventional acupuncture group and warming acup-moxibustion group were lower than those of the model group (P < 0.05), and the heat needle group had the lowest levels. HE staining results showed that heat needle group had milder inflammatory reaction and better muscle fiber structure than the model group. Conclusion Heat needle treatment can improve the local inflammatory response and promote the repair of tissue damage through decreasing the expression levels of inflammatory cytokines of TNF-α, IL-1βand IL-6.

Objective:
To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP).
Methods:
Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats.
Results:
The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC.
Conclusion
SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity.

Regarding every 5 years as a research stage, the whole period was divided into 7 stages to analyze the pathological features and variation of renal biopsies. The first stage (P1) started from August 1986 to December 1990. The second stage (P2) started from January 1991 to December 1995. The third stage (P3) started from January 1996 to December 2000. The fourth stage (P4) started from January 2001 to December 2005. The fifth stage (P5) started from January 2006 to December 2010. The sixth stage (P6) started from January 2011 to December 2015. The seventh stage (P7) started from January 2016 to December 2020.Results:The age was (36.47±14.86) years old (18-83 years old) in 5 652 renal biopsies. There were 2 961 males (52.39%). There were 5 636 cases of autologous kidney biopsy and 16 cases of transplanted kidney biopsy. The descending order of incidence classified by disease types were primary glomerular disease (PGD, 4 470 cases, 79.31%), secondary glomerular disease (SGD, 994 cases, 17.64%), tubular-interstitial disease (160 cases, 2.84%), and hereditary nephropathy (12 cases, 0.21%). IgA nephropathy (IgAN, 1 573 cases, 35.19%) was the most frequent pathologic type of PGD, followed by membranous nephropathy (MN, 1 028 cases, 23.00%), mesangial proliferative glomerulonephritis (MsPGN, 878 cases, 19.64%), minimal change disease (MCD, 427 cases, 9.55%), and focal segmental glomerulosclerosis (345 cases, 7.72%). Lupus nephritis (LN, 251 cases, 25.25%) was the most common type of SGD, followed by hypertension nephropathy (193 cases, 19.42%), diabetic kidney disease (168 cases, 16.90%), purpura nephritis (138 cases, 13.88%), and ischemic nephropathy (90 cases, 9.05%). IgAN was the most common type of primary glomerulonephritis and mainly occurred in the age group of 18-59 years old. PGD was the most common glomerular disease in Han nationality (78.33%), Uygur nationality (81.72%) and other ethnic (77.15%) groups. Using Bonferroni correction method, the incidence of PGD in Uygur nationality was higher than that in Han nationality ( P<0.017). From P1 to P7, the detection rates of MN and MCD were increased in common renal pathological types, meanwhile, the ratio of MsPGN was decreased (all P<0.05). From P5 to P7, the detection rates of MN in Han nationality and Uygur nationality increased in the common pathological types of PGD, meanwhile, the ratio of MsPGN decreased (all P<0.05). LN was the most common SGD. The incidence of LN in females was higher than that in males ( P<0.001). Using Bonferroni correction method, the incidence of SGD in Uygur nationality was lower than that in Han nationality ( P<0.017). There was no significant variation in the common pathological type of SGD in Han and Uygur nationalities. Chronic rejection was the main pathological type of transplanted kidney biopsies. Conclusions:PGD is the main type of kidney disease spectrum in People's Hospital of Xinjiang Uygur Autonomous Region. IgAN is the most common PGD and mainly occurrs in the age group of 18-59 years old. As time goes by, the proportion of MN and MCD is increased, meanwhile the proportion of MsPGN is decreased significantly. LN is the most common SGD.

Because the work of administrative and logistics personnel in public hospitals is difficult to quantify and evaluate, its performance reform is difficult. A large public hospital in Wuhan has explored and established a distribution incentive mechanism that combines department performance appraisal, individual classification and grading, and secondary distribution within the department. Taking into account the completion of performance appraisal indicators of the national tertiary public hospital in the department, the results of the institutional " Excellent Management Team Ranking" , personal job grades, working years and other factors, a relatively mature and operable system has been formed, which could provide reference for the performance reform of other hospitals.

OBJECTIVETo explore the role of µ-opioid receptors (MOR) in the central nucleus of the amygdala (CeA) in modulating sucrose solution intake in rats.
METHODSSprague-Dawley rats received intra-CeA injection of MOR agonist DAMGO or saline, and then underwent two bottle choice test between sucrose solution and distilled water. After intake of sucrose solution or distilled water, activated neurons in the CeA were labeled and identified with MOR/Fos-double labeling immunohistochemistry.
RESULTSCompared with saline injection, intra-CeA injection of DAMGO significantly increased sucrose solution intake in rats over a 3-h period. Sucrose solution intake induced significantly more c-Fos and MOR/Fos double-labeled neurons in the CeA than distilled water intake.
CONCLUSIONSThe CeA participates in modulation of sucrose intake in rats, and MOR may partly mediate this mechanism.
