Objective To investigate the efficacy of transverse insertion of thick needles into the Du meridian in treating rat ischemic facial paralysis and preliminarily explore the possible mechanism by which it produces a therapeutic effect. Methods Sixty Wistar rats were randomly allocated to groups A (transverse insertion of thick needles), B (basic Western drugs), C (blank control) and D (sham operation), 15 rats each. A rat model of ischemic facial paralysis was made using a modified vascular occlusion method in all the rats. Facial nerve deficits were scored in every group of rats during treatment. At 1 day after model making, group A was treated by transverse insertion into point Shendao and 4-hour retention of needle, once daily, for a total of 14 days; group B was treated by an oral gavage of prednisone and intraperitoneal injection of vitamine B12, once daily, for a total of 14 days. Groups C and D were not treated. In 4 rats randomly chosen at 3, 7 or 14 days after model making, facial nerve concomitant intrinsic vascular tissue HIF-1αprotein was measured by an immunohistochemical method; serum NO, by enzyme-linked immunosorbent assay; serum ET content, by radioimmunoassay.Results After 7 days of treatment, the neurological deficit score increased gradually in groups A and B and there was a statistically significant difference compared with after model making in the two groups (P<0.01). After 7 days of treatment, there was a statistically significant difference in the neurological deficit score in groups A and B compared with groups C and D (P<0.05) and between groups C and D (P<0.05). After 14 days of treatment, there was a statistically significant difference in the neurological deficit score between group A or B and group C (P<0.05) and between group B or C and group D (P<0.05). In group A, there was a statistically significant difference in the neurological deficit score after 14 days of treatment compared with after 7 days of treatment (P<0.05). After 3, 7 and 14 days of treatment, there was a statistically significant difference in HIF-1αMOD value in groups A , B and C compared with group D (P<0.01). After 3 and 7 days of treatment, there was a statistically significant difference in HIF-1αMOD value between group A or B and group C (P<0.05). In groups A and B, there was a statistically significant difference in HIF-1αMOD value after 3 and 14 days of treatment compared with after 7 days of treatment (P<0.05). After 3 and 7 days of treatment, there was a statistically significant difference in serum NO content between group A or B and group D (P<0.01). In groups A and B, there was a statistically significant difference in serum NO content after 7 days of treatment compared with after 3 days of treatment (P<0.05). After 3 and 7 days of treatment, there was a statistically significant difference in serum ET content in groups A , B and C compared with group D (P<0.05). In groups A and B, there was a statistically significant difference in serum ET content after 7 days of treatment compared with after 3 days of treatment (P<0.05).Conclusions Transverse insertion of thick needles into the Du meridian can effectively promote rat’s recovery from ischemic facial paralysis. The mechanism by which it produces a therapeutic effect may be regulating the expression of tissue HIF-1α and the NO and ET contents of serum.

Objective:
To compare the safety between cervical conization (CC) alone and hysterectomy for patients with adenocarcinoma in situ (AIS) of the cervix.
Methods:
Patients diagnosed with AIS after CC during 2007–2021 were identified by computerized databases at Women’s Hospital of Zhejiang University School of Medicine. A total of 453 AIS patients were divided into 2 groups according to uterus preservation: hysterectomy group (n=300) and CC(s) alone group (n=153). The prevalence of residual disease and disease recurrence was compared between patients treated by CC(s) alone and hysterectomy. The prevalence of residual disease in specimens from women who had a hysterectomy and repeat CC were compared between positive and negative margins of CC. The factors influencing residual disease and disease recurrence were assessed.
Results:
Among 310 specimens from women who had a hysterectomy or repeat CC, the prevalence of residual disease was 50.6% (45/89) for a positive margin and 2.3% (5/221) for a negative margin (p=0.000). Four patients had recurrence of vaginal intraepithelial neoplasia in those treated by hysterectomy and one had recurrence of cervical squamous intraepithelial neoplasia in those treated by CC(s) alone. The prevalence of recurrence was 0.7% (1/153) for CC(s) alone and 1.3% (4/300) for hysterectomy (p=0.431). Hysterectomy did not influence residual disease or disease recurrence.
Conclusion
CC is an efficacious and safe option for patients with AIS of the cervix provided the margin is negative.

OBJECTIVETo investigate the protective effect of insulin on oxygen-radical induced hepatic injury in severely scalded rats in early stage of severe scald.
METHODSEighty-four male Sprague-Dawley rats were randomly divided into three groups: i. e, normal group, saline group, and insulin group, with 28 rat in each group. The rats in the latter two groups were subjected to 30% TBSA full-thickness scald on the back, and received intra-peritoneal injection of 40ml/kg isotonic saline, and subcutaneous injection of 3 IU/kg insulin, respectively. The total anti-oxygen capability (T-AOC), the expression of superoxide dismutase (SOD), reactive oxygen species (ROS) and intercellular adhesion molecule (ICAM-1) in hepatic tissue, and serum alanine transaminase (ALT) were determined in each group at 6, 12, 24, 48 post-scald hours (PSH) with corresponding methods.
RESULTSThe hepatic T-AOC and SOD content were obviously decreased, while the ROS content were markedly increased at 6 PSH in saline group compared with that in normal group (P < 0.05 or P < 0.01). The expression of ICAM-1 and serum content of ALT were significantly higher than that in normal group at 12 PSH and 48 PSH (P < 0.01). At 24 PSH, the hepatic T-AOC (386 +/- 75) U/g and SOD content (210 +/- 39 ) U/g were obviously higher in insulin group than those in saline group [(124 +/- 18), (111 +/- 9) U/g, respectively, P < 0.01), but the ROS content (154 +/- 29 ) U/g was much lower than that in saline group [(351 +/- 41) U/g, respectively, P < 0.01]. At 48 PSH, the serum content of ALT and hepatic expression of ICAM-1 in insulin group exhibited obvious difference when compared with those in saline group (P < 0.01). Meanwhile, Pathological examination showed that hepatic injury was alleviated by insulin administration after scald.
CONCLUSIONInsulin administration early after severe scald exhibits protective effect on liver function by improving anti-oxygen radical ability of rat liver.

OBJECTIVETo compare the in vitro inhibitory effect of expolysaccharides from Streptomyces, polysaccharides of Ganoderma lucidum and rice bran on six-alpha-helix bundle formation of HIV gp41 protein.
METHODSThe amount of six-alpha-helix bundle formed in the presence of N36 and C34 was tested by ELISA in response to treatments with different doses of polysaccharides.
RESULTSExpolysaccharides from Streptomyces potentially inhibited six-alpha-helix bundle formation with the effective concentration (IC(50)) of 145.48-/+7.25 mg /L. Polysaccharides of Ganoderma lucidum and rice bran showed no effect on the six-alpha-helix bundle formation.
CONCLUSIONExpolysaccharides from Streptomyces can inhibit the six-alpha-helix bundle formation of HIV gp41, whereas polysaccharides of Ganoderma lucidum and rice bran do not exhibit such activity.

Objective To investigate the impact of age on patients with metabolic syndrome (MS) and normal persons. Methods Data was gathered from 8280 persons including 4873 males and 3407 females who were randomly selected. All subjects were devided into normal group and MS group. According to the interval of ten years, the subjects were devided into seven age groups, to calculate the difference of impaired fasting glycaemia (IFG) between patients with diabetes mellitus (DM) and normal people, as well as the related portions. Results (1) The risk of IFG and DM appeared to be different among age groups among the target subjects as well as in the normal and the MS groups (P<0.05). (2) Among the whole subjects, the overall prevalence of IFG was increasing with age. The prevalence of DM had an increasing trend with age augment in 20-79 years group, whereas a decreasing trend appeared in people over 80 years of age. (3) For normal persons, the prevalence of IFG and DM were all increasing with age augment in 20-79 years group, and then decreasing with age augment in the over-80-years group. (4)For MS patients, the prevalence of IFG had an increasing trend with age augment in 20-69 years group, whereas a decreasing trend appeared in people over 70 years of age. There was no tendency of variation with age augment in DM.Conclusions (1) For normal persons, high prevalence rates of IFG and DM were correlated to age augment, especially in senior persons. (2) For MS patients, high prevalence of IFG was also correlated to age augment, but no association between prevalence of DM and age augment was seen. (3)Age from 70 to 79 years appeared to be in high risk with MS.

OBJECTIVETo investigate the Th17 cell and Treg cell levels in patients with sarcoidosis, and their relation to disease activation and glucocorticoids treatment.
METHODSTwenty-three sarcoidosis patients admitted in Yinzhou People's Hospital from January 2009 to December 2013 and 25 healthy subjects (controls) were included in this study. The blood samples and bronchoalveolar lavage fluid (BALF) samples were collected in all patients before and after glucocorticoids treatment. The serum angiotensin converting enzyme (SACE) levels were detected. The percentages of Th17 cells and Treg cells in peripheral blood and BALF were determined by flow cytometry, the concentrations of cytokines in serum and supernatants of BALF were measured by enzyme-linked immunosorbent assay (ELISA). The levels of ROR-γt and Foxp3 mRNA transcripts in peripheral blood mononuclear cells (PBMC) were determined by real-time quantitative PCR. The potential correlation between the percentages of Th17 or Treg cells and SACE levels was evaluated.
RESULTSCompared with healthy controls, significantly higher frequencies of Th17 cells (4.34%±0.89% vs 1.60% ± 0.42%), lower frequencies of Treg cells (1.28% ± 0.37% vs 3.39% ± 0.50%) in peripheral blood were observed. Higher level of ROR-γt mRNA (21.31 ± 3.55 vs 3.63 ± 1.00) and lower level of Foxp3 mRNA (1.60 ± 0.24 vs 3.12 ± 0.76) in peripheral blood were detected in sarcoidosis patients in active stage (before glucocorticoids treatment) (all P<0.01). After the treatment of glucocorticoids, these index in peripheral blood were significantly improved (Th17 cells 2.16% ± 0.68%,Treg cells 2.21% ± 0.42%, ROR-γt mRNA 10.15 ± 1.93, Foxp3 mRNA 2.44 ± 0.38) ( all P<0.05). The changing trends of Th17 and Treg cell cytokines levels in serum were consistent with two type cells. Meanwhile, the changing trends of above index in BALF of patients treated by glucocorticoids were consistent with those in sarcoidosis patients in active stage. The increased ratios of Th17 cells to Treg cells were positively correlated with the level of serum SACE (r= 0.781).
CONCLUSIONThe imbalance of Th17 cells and Treg cells in peripheral blood and airway may be involved in the pathogenesis of sarcoidosis, which was associated with the activity of disease, and the treatment of glucocorticoids may achieve a therapeutic effect by correcting the immune imbalance.

OBJECTIVE:
To quantify the purine concentrations of the acupoints along the pericardium and nonpericardium meridians under healthy and myocardial ischemia conditions to investigate the relationship between acupoint purine change and body functional status in rats.
METHODS:
A total of 70 rats underwent an operation for myocardial ischemia, while 40 of them survived. They were randomly assigned to the following 5 subgroups: Neiguan (PC 6), Quze (PC 3), Tianquan (PC 2), Quchi (LI 11), and Jianyu (LI 15). Simultaneously, another 40 healthy rats were also randomized into the same 5 subgroups as the control group. The tissue fluids at the acupoints were collected by microdialysis for 30 min. Subsequently, the concentration of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), and adenosine (ADO) were quantified using the high-performance liquid chromatography method.
RESULTS:
Compared with the healthy group, the ADO at PC 6 (P=0.012), PC 3 (P=0.038), PC 2 (P=0.024), and LI 15 (P=0.042) obviously increased in the model group, while no significant difference was observed at LI 11 (P=0.201). However, ATP, ADP, and AMP manifested no significant changes in these areas, except for ATP at LI 15 (P=0.036).
CONCLUSIONS
Myocardial ischemia could induce an increase in ADO at acupoints of the upper arm and shoulder area, suggesting that the body functional status could affect the responsiveness of acupoints. The status of these acupoints could be pathogenically activated by disease, and distribution following some specific courses.
